1       EXECUTIVE SUMMARY

1.1     Background

     The Regional Airport System Plan (RASP) is an appendix to the
Metropolitan Transportation Commission's (MTC's) long-range
Regional Transportation Plan (RTP) and provides an assessment of
future aviation requirements and suggested improvements for the
nine-county San Francisco Bay Area.  The current update is the
first significant revision to the Regional Airport Plan in a number
of years, and will provide recommendations to be incorporated into
MTC's 1994 Regional Transportation Plan update.  There is also an
environmental study that describes the impact of aviation
development on community noise, regional air quality, the Bay, and
other important environmental impact areas.

     Statutory authority for MTC to prepare the RASP is contained
in California Government Code Section 65080(a), requiring that each
Regional Transportation Plan include aviation facilities.  In
addition, California Government Code Section 65081.1 provides that
an updated regional transportation plan must include an airport
ground access improvement program" for the "development and
extension of mass transit systems".

Purpose of the Plan

The purpose of the Regional Airport System Plan is threefold:

   1.   To assess the long-range requirements for new and improved 
        aviation facilities in the region, both air carrier and
        general aviation.
   2.   To evaluate tradeoffs in terms of optimizing system 
        capacity, managing the airport ground access system, 
        minimizing adverse environmental impacts, and maintaining
        compatibility of land uses around airports.
   3.   To develop public consensus behind proposed improvements.

Goals and Objectives

   A.   Improve Regional Access to Air Service

   1.   Provide air passenger facilities that will be convenient in
        terms of their location  and accessibility for regional air
        travelers and airport employees.
   2.   Provide general aviation facilities that will be convenient
        in terms of their location and accessibility for both
        business and non-business aircraft owners.
   3.   Provide improved transit and highway connections to air 
        carrier and general aviation airports to enable air
        travelers, airport employees, cargo shippers, and other 
        airport users to quickly and reliably make ground access
        trips to and from Bay Area airports.

Chapter 1: Executive Summary                       September 9, 1994

   B.   Improve System Safety and Efficiency

   1.   Support measures to increase runway and airspace 
        utilization as a means to maximize the use of existing
        airfield capacity (e.g., larger aircraft, higher load 
        factors, better scheduling of airline flights to reduce 
        runway overload, and technological improvements in the air
        navigation system).
   2.   Ensure that airport system improvements do not compromise
        air safety.
   3.   Ensure that runways, taxiways, and other critical airport 
        facilities are well maintained.
   4.   Provide facilities at the airports that improve efficiency
        of operation for airport  users (e.g., expanded terminals
        and additional gates, internal airport  circulation  roads, 
        modem cargo facilities, new hangar facilities for general
        aviation, etc.).

   C.   Promote Equity for System Improvements

   1.   Seek an equitable distribution of airport system benefits
        (access to air service in terms of destinations, frequency,
        fares, etc.) and impacts (local traffic congestion, noise,
        air pollution, and other land use impacts).
   2.   Develop an airport access system that provides efficient 
        and affordable ground access from all parts of the Bay Area.
   3.   Provide an equitable decision-making process in developing 
        the Regional Airport System Plan.

   D.   Promote Sensitively to the Environment

   1.   Minimize regional (and, to the extent possible, local)
        community noise exposure.
   2.   Minimize air pollution from auto and aircraft activity.
   3.   Minimize energy consumption from auto and aircraft activity.
   4.   For projects requiring Bay fill or taking of wetlands, seek
        solutions that result in no net impact and, further, that
        enhance these resources.
   5.   Ensure safety for people on the ground.

   E.   Promote Economic Vitality

   1.   Support air service improvements in domestic and 
        international markets as a means to stimulate commerce
        (business and tourism).
   2.   Support airport improvements consistent with the regional
        plan as a means to foster local economic vitality for
        communities around airports.
   3.   Reduce runway and airspace delays that generate airline
        costs and lead to higher air fares for air passengers and
        cargo shippers.
   4.   Maintain land use compatibility around airports to avoid
        adverse impacts on future airport operational capabilities.

1.2     Critical Aviation Issues for the Region

     The Need for New Capacity, The defining issue for the Bay
Area's airport system is the adequacy of the existing runways and
airspace to accommodate future growth in air carrier and general
aviation activity.  The forecasts of future activity represent the
"best estimate" of probable activity levels, and are usually
presented as a range of values to hedge against inherent
uncertainties in the underlying assumptions.  Expansion of existing
air carrier airport runways presents numerous policy issues related
to environmental constraints (community noise impacts, Bay fill,
wetland impacts, endangered species impacts, local traffic impacts,
etc.) that must be carefully weighed in relation to overall
regional benefits.  In contrast, development of an entirely new
airport (e.g., in the North Bay) will take years of planning and
public input, will certainly face some amount of public opposition,
will be costly, and may have an equally difficult set of
environmental concerns to address.  In contrast to the air carrier
system, reduced activity at the region's general aviation airports
will result in these airports having adequate runway and parking
capacity to meet projected demand over the 20-year planning
horizon.  The chief need at these airports is a high level of
demand for enclosed hangar space for based aircraft.

     Airport Master Plans.  The Regional Airport System Plan has
used existing airport master plans, either adopted or currently
under development, as the basis for much of the planning that has
been undertaken in this update.  Proposals from these plans can be
compared to regional goals and objectives as outlined above.

     San Francisco Airport's Master Plan was completed and adopted
by the Airports Commission on November 3, 1992; it would add, among
other things, a new international terminal; a new ground
transportation center; a light rail system; and a new access road
system.  No new runways are planned.  BART has also proposed, and
MTC has programmed partial funding for, a BART extension to the
airport.

     Oakland Airport's Master Plan is under way and extends to the
year 2002; the plan does not anticipate the need for a second
parallel air carrier runway in this time frame; several regional
airport plan alternatives presented in the RASP Environmental
Impact Report include a second runway for analysis purposes.

     San Jose Airport is also in the midst of a master planning
study, which proposed further terminal expansion, but no new
runways or general aviation facilities; air cargo handling
capability may be restricted due to a lack of space at the airport;
relocation of general aviation is being considered due to runway
capacity constraints.

     Travis Air Force Base (AFB) has joint use potential, but it is
not currently necessary to activate this potential; military
operations may increase at Travis in the future as other military
bases are closed around the country and in California; a joint use
agreement with the Air Force has lapsed

and would need to be renegotiated if civilian air carrier service
is desired in the future.

     General Aviation Airports: The general aviation segment of
aviation has been declining, but it is unlikely this trend will
continue; most airports have completed an Airport Master Plan, but
given the aforementioned decline, the impetus to do long range
planning has diminished; priority concerns for most general
aviation airports will be to maintain existing facilities, to
protect against further development encroachment, to provide a
supporting role to air carrier facilities in terms of accommodating
based aircraft and itinerant flight activity, and to add new hangar
space to protect aircraft from weather.

     Military Airports: the prospective need for Hamilton (Army)
and Moffett (Navy) airfields have been prominent concerns in
development of the regional airport plan.  While Moffett's future
use as an aviation facility is secure under National Aeronautics
and Space Administration (NASA) ownership, the remaining aviation
portions of Hamilton Army Airfield will likely be relinquished to
local jurisdictions for non-aviation uses due to a lack of a local
airport sponsor.  Alameda Naval Air Station (NAS), just surplused
by the Department of Defense (DOD), may have an aviation niche, but
its preservation is not critical to the functioning of the regional
airport system.

     Ground Access Constraints: Each of the major air carrier
airports will face critical ground access constraints in the
future, which will result in passenger delays, potentially missed
flights, disruption to air cargo delivery, and parking overload. 
The regional plan addresses this issue by assessing ways to balance
use of the three major airports, shorten vehicle trips, provide
better transit connections, and improve roadways for more efficient
airport access.

     Environmental issues: A detailed assessment of community noise
exposure, air quality, and other environmental impacts associated
with the recommended Regional Airport System Plan is provided in a
separate Environmental Impact Study.  Additional environmental
review will also be conducted where required for specific airport
development projects that are described in the Draft RASP. 
Generally speaking, technological advancements in aircraft engines
and private automobiles will result in reduced airport community
noise exposure and reduced airport ground access pollution under
all alternatives.  Regional noise exposure and ground access
emissions will be further influenced by the regional distribution
of air travel demand around the Bay Area air carrier airports.  The
general aviation airport system will not experience significant
changes in noise exposure since the noise characteristics of the
piston powered general aviation fleet is not expected to change
appreciably in the future.  In addition, the RASP environmental
study addresses potential environmental impacts on a regional
level. Subsequent analyses for individual airports are expected to
focus more specifically on impacts  unique to those local
environments.

1.3     General Conclusions

     The following sections discuss the key findings from the
regional study of aviation requirements and present the background
for the major recommendations.

Aviation Forecasts

     For the period 1990 to 2010 projected growth rates and maximum
activity levels for the regional airport system were developed as
follows:

System Component                 %Growth        Max. 2010 Volume

Air Passengers                        67-100%   84 million travelers
Air Carrier Aircraft Operations        54-78%     933,000 operations
Air Cargo Volume                      108-230%     3.1 millions tons
General Aviation Based Aircraft         -3-25%       8,700 aircrafts
General Aviation Aircrat Operations      6-37%  4 million operations


These projections were developed for the purpose of regional
airport system policy planning.  Project level planning or design
at individual airports will utilize forecasts developed as part of
the airports' master plans.  Individual airport master plans that
are developed subsequent to this Regional Airport System Plan will
contain forecasts that may supersede these.

Air Carrier Airport Capacity

The comparison of existing airport system capacity with future
activity levels is the basis for developing airport system
improvement alternatives and recommendations.  The evaluation of
the adequacy of future airport system capacity is contingent on a
number of factors that have been assumed in the analysis and that
represent favorable conditions in terms of optimum use of airport
and airspace capacity.  These factors include the following:

   1.   Significant redistribution of flights between airports
   2.   Significant growth in aircraft seating capacity and airline
        load factors, resulting  in  the following increases in
        passengers per airline operation at each airport:


   SFO            78-120 (54%)
   OAK            45-75 (67%)
   SJC            47-75 (60%)
   Travis AFB     75

   3.   A six percent reduction in demand at the three major air 
        carrier airports due to a combination of the following:
        continuation of limited airline service at Concord and
        Sonoma County general airports, new service at Travis AFB
        and/or introduction of California intercity high speed rail
        service between Los Angeles and the Bay Area.

   4.   Diversion of some general aviation flights from air carrier
        to other non-air carrier airports.

   5.   Exhibit 1.1 shows that, under the assumptions discussed
        above, the primary air carrier airports (San Francisco,
        Oakland, San Jose) can accommodate annual demand in 2010,
        except that San Jose Airport will operate at 'unacceptable'
        levels of delay. During peak hours, both Oakland and San
        Francisco will operate at 'unacceptable' levels of delay
        'under Visual Flight Rule (VFR) conditions, Under 
        Instrument Flight Rule (EFR) conditions, all airports will
        operate at "unacceptable" levels of delay during the peak
        hours.

   6.   The primary means for alleviating airport system capacity
        shortfalls would be through addition of new runways; some
        examples of possibilities include:

        a.   A new parallel runway at OAK with 700 to 800 ft of 
             separation from the existing runway would increase 
             annual capacity by 100,000 operations and VFR/EFR
             capacity by 43 and 10 operations per hour,
             respectively; this option would affect about 135 acres
             of wetland (inboard runway option) or 57 acres of Bay 
             fill (outboard runway option).

        b.   New parallel runway at Oakland with 2,500 ft of 
             separation from the existing runway would increase 
             annual runway capacity by some 100,000 operations and
             peak hour VFR/IFR capacity by 52 and 25 operations 
             (this options would require 387 acres of Bay fill or
             impact 68 acres of freshwater wetland).

        c.   A new air carrier instrument runway in the North Bay 
             serving predominantly air carrier activity would
             increase annual capacity in the range of 200,000-
             250,000 annual operations and VFR/IFR capacity by 
             between 51 and 50 operations per hour, respectively.

   7.   Implementation of new FAA procedures and demand management
        measures could potentially increase runway capacity by 6-7 
        percent and decrease peak hour airline operations by 9-10
        percent; however, these estimates represent the outer bound
        of what can be assumed to be reasonably achievable.

Airport Convenience

     If passengers could choose among regional airports based on
access distance alone (assuming equal flight availability), the
following shares would result*:

   Airport             Market Share

   SFO                      48.1%
   OAK                      20.8%
   SJC                      22.9%
   Travis AFB                7.7%
   Concord, Sonoma Co.       0.5%

* Based upon the results of MTCs "ACCESS" model.

1-7

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


     If a more realistic flight schedule is assumed for OAK and
SJC, (i.e., passengers only have selected flight destination
options from these airports, generally in the larger air travel
markets), then airport passengers shares would be expected to be as
shown below:

   Airport             Market Share

   SFO                        59%
   OAK                      16.0%
   SJC                      19.0%
   Travis AFB/Rail           5.5%
   Concord, Sonoma Co.       0.5%


Air Carrier Airport Terminal Capacity

Total airline gates required at the region's air carrier airports
will increase from 142 in 1990 to between 162 and 210 gates in the
year 2010.

General Aviation Airport Capacity

As a system, Bay Area general aviation airports are currently
operating at about 46 percent of their annual runway capacity and
about 79 percent of based aircraft parking capacity; 2010 forecasts
indicate the region's general aviation airports would operate at
about 59 percent of their annual runway capacity and 87 percent of
their aircraft parking capacity.

Since general aviation facilities are not expected to operate near
their capacity, most airports have the capability to accommodate
additional activity.  One key role of these airports will be to
complement the capacity of the air carrier airports by providing
alternative facilities for general aviation users, i.e., to serve
as "reliever" airports for the air carrier airports.  Accommodating
a portion of the general aviation activity at these airports will
effectively increase runway capacity by 3.6 million passengers (at
20 passengers per operation); diversion of 21,000 general aviation
operations at Oakland's South Field would effectively increase
runway capacity by 2 million annual passengers (at 90 passengers
per operation).  San Jose Airport will require significant
diversion of general aviation based aircraft and VFR/IFR operations
to meet its regional air passenger share.  Strategies to achieve
high levels of diversion include airport pricing and development of
attractive and convenient reliever facilities.

A related issue is the need to provide new IFR runway capacity for
the Bay Area airport system, including general aviation airports. 
Absent additional IFR capacity, general aviation aircraft will
continue to rely on the air carrier airports for all-weather
operations, aggravating already significant delay problems at these
facilities.  A promising trend is the growing number of corporate
general aviation aircraft being equipped with new navigational aids
(Loran C and

Global Positioning System).  This equipment could enable airports
not currently equipped with instrument landing systems to accept
some level of IFR operations.

     In the longer term, the region's general aviation airports
could provide suitable sites for selected air cargo activity,
Tiltrotor passenger aircraft for short haul scheduled airline
service, or remote ground access terminals with parking and baggage
check in for the shuttle services to SFO, OAK, or SJC airports.

Airport Ground Access

     Daily vehicle trips by air passengers to Bay Area air carrier
airports will increase by 90 percent between 1990 and 2010, and
daily vehicle miles travelled (VMT) by approximately 100 percent. 
Accommodating a higher share of regional air travel demand at
Oakland and San Jose airports would result in about 4-8 percent
reduction in airport access vehicle trips and distances.  The
higher range of reduction includes the effect of an "tension of
mass transit (BARL) to San Francisco Airport.

Environmental Issues

Environmental factors are generally favorable with respect to
accommodating additional air passenger and general aviation
activity at Bay Area airports under the Plan proposal:

1.      Airline fleet changes will reduce community noise exposure
        in the Bay Area from 42.1 acres in 1990 to 18.6 acres in
        2010.

1-9


MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994

   2.   Air quality impacts will decline, primarily due to the
        reduced automobile emissions for airport access journeys
        resulting from the use of lower emitting passenger vehicles.

   3.   The Bay and its wetlands would not be affected as the plan
        does not propose new facilities affecting these natural
        resources; the Plan does propose a reevaluation of the need
        for a second runway at Oakland Airport at Stage 3 levels of
        regional passenger activity, and this runway would have Bay
        or wetland impacts.

   4.   Airport access traffic measured in total vehicle miles of
        travel will increase; freeway levels of service adjacent to
        each airport would be expected to decrease due to added
        airport trips being served by these new airport facilities
        (passenger terminal, General Aviation facilities, runways,
        etc.).

     Site-specific impacts to the Bay and its wetlands, air and
water quality, traffic, and other issues, will be the subject of
subsequent environmental analyses for individual projects.

   5.   Preserving land use compatibility for air carrier, general
        aviation, and  military  airports is contingent on the
        success of the local decision-making  process involving 
        airport land use commissions ("ALUC's") and local 
        jurisdictions; further residential infill and encroachment
        of tall structures into the airspace near airport runways
        are  key  concerns.

Airport Improvement Costs

     Air carrier airports generally have the financial capacity to
undertake major expansion programs from user revenues, concessions,
and FAA airport trust fund monies; smaller general aviation
airports rely more on federal and state grants for improvements.  A
summary of major airport improvement costs for each airport is
contained in Chapter 9 of the main report.

1.4     General Plan Recommendations and Policy Basis

Air Carrier Airports

   1.   The Plan supports a redistribution of regional air passenger
        activity among the air  carrier airports to better balance
        system demand with  capacity,  provide  more  convenient 
        access to air service for  Bay  Area  residents,  and 
        minimize environmental  impacts  associated with a 67-100
        percent increase in passenger demand between 1990 and 2010.

   2.   The Plan recognizes the uncertainty in  determining  when 
        forecasted  levels  of  passenger activity will actually
        occur, and therefore proposes that airport traffic  shares 
        be  keyed to specific levels of activity for the Bay Area 
        as  a  whole;  this  approach  will  enable airport
        operators to understand the Plan's expectations for improved
        facilities,  given  the overall level of demand being
        experienced by Bay Area airports as a group.

Regional Airport Passenger Shares

     The Regional Airport System Plan recommends the following
desired airport traffic shares at each level (stage) of air travel
growth in the Bay Area; the intent of these policy allocations is
to achieve greater passenger convenience, minimize airspace delay,
reduce the number and average length of surface access trips to
airports and resulting vehicle emissions, and minimize total noise
exposure for Bay Area residents.  Exhibit 1.4 below displays the
regional airport assignments for the air carrier airports. 
Exhibits 1.5 and 1.6 display the entire spreadsheet analysis for
the year 2010 air carrier airport system plan for both the high and
the low passenger forecasts.  Stage I is the base activity level
for the regional airports, and represents 1990 conditions.

RECOMMENDED AIRPORT TRAFFIC SHARES
(Annual Air Passenger Demand, Millions of Passengers)

*  Refers to the time frames for plan implementation, eg.,
   immediate, short, medium, long term.

     The traffic shares for Oakland and San Jose reflect the shares
that each airport could achieve given a realistic flight schedule
to major California, other domestic, and international
destinations; it is specifically noted that San Francisco Airport
would continue to provide air service to a number of destinations
that would not be served by Oakland or San Jose airports.

     Initiation of new airline service at outlying airports, like
Travis AFB, will depend on actions by local communities to secure
airline commitments and to develop new facilities.  The most likely
markets for satellite airport service would be to cities in
Southern and Central California.  Initiation of some air service in
the North Bay would result in a more equitable distribution of air
carrier service benefits and impacts compared to the current
situation.

     California high speed rail does not yet have an investment
plan that will generate competitive rail service, and major
diversion of air passengers to rail cannot be expected in the
foreseeable future.

     The existing Bay Area air carrier airport system is only
marginally capable of handling forecasted peak period demand (given
the planning assumptions discussed above) and will experience
unacceptable VFR and IFR delays during the planning period.  As
suggested in this Plan further analysis will be required to
determine the timing and location of new air carrier runways. 
Specifically, the Plan calls for a reevaluation of the second
runway option at Oakland Airport at Stage 3 levels of regional
demand.  Policies relating to passenger convenience, airspace
management, regional noise exposure and economic benefit would
support development

1-12




MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


of a second runway at Oakland Airport to provide the next major
increment of airport system capacity.  Clearly other policies in
the plan would also need to be concurrently addressed, such as
those relating to environmental impacts.

     In order to help alleviate traffic congestion on the freeways
and connecting roads to the airport terminals, the three major air
carrier airports should each have an efficient mass transit
connection to provide air travelers with alternatives to use of the
automobile.  Because of regional rail agreements and regional
funding constraints identified in the 1994 Regional Transportation
Plan, a connection would first be made to the San Francisco Airport
(BART/CalTrain), and connections to Oakland and San Jose airports
would be dependent on new transportation funding.

General Aviation

     Overall, the Plan endorses the Airport Master Plan Alternative
with comments and modifications as explained below.  Under the
"high" general aviation forecast of based aircraft, only airports
would reach their based aircraft capacity by 2010 (Concord, San
Carlos, San Jose).  No significant runway capacity improvements are
required as airfield capacity would be adequate to meet future
demand.  The Master Plan alternative would encourage a proportional
shift of based aircraft and aircraft operations to outlying general
aviation airports; this outcome is desirable in that it creates a
system that directs more flight activity to the least congested
portions of the Bay Area's airspace.  The Plan also supports
greater use of these outlying airports for flight training, again
as a means to promote air safety.  Another outcome of the Master
Plan alternative would be the fulfillment of a large part of the
demand for enclosed hangar space.  Additional issues are discussed
below:

     Hamilton Army Air Field (AAF) would be deleted from the Plan
as a regional general reliever airport.  Recent solicitations
related to the Army's surplus process show that there is no local
sponsor willing to operate the airport as a general aviation
reliever facility.  If the airfield is flooded or developed as
wetlands, the Plan proposes that the acreage created in this manner
be 'banked" as mitigation for possible development of airport
projects elsewhere in the Bay Area subject to agreements between
the Bay Conservation and Development Commission (BCDC), MTC, the
Federal Aviation Administration (FAA), and federal resource
agencies.

     Moffett Field.  In recognition of the continuing NASA
operation of this facility for the benefit of federal agencies and
defense contractors, the Plan does not propose any civilian use of
this facility at this time.  There is a continuing regional
interest in potential civilian use of Moffett, and this interest
would be activated if and when NASA no longer requires exclusive
use of the facility.  'The context for the regional interest in
Moffett is for a reliever airport or for other civilian uses as
described above under the discussion of general aviation capacity.

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994

     Reid Hillview should be retained as part of the South Bay
general aviation system in that it serves a large population of
users and provides relief to San Jose Airport; alternatively, a
replacement facility with comparable capabilities and more
compatible land use could be developed at another location in Santa
Clara County.

     South County could be developed to serve substantially greater
activity than contemplated in the existing Airport Master Plan.  As
runway constraints become more critical at San Jose Airport, South
County's Master Plan should be revisited to determine if this
facility could provide for the needed diversion of operations and
based aircraft from San Jose Airport.

1.5     Detailed Airport-Specific Recommendations 

San Francisco International (SFO)

     SFO would develop additional ground access and passenger
terminal facilities to serve projected passenger and air cargo
growth.  This development would take place according to the Airport
Master Plan (adopted November 3, 1992), and would be accommodated
with existing runways.  The Regional Airport System Plan supports
the following SFO Airport Master Plan projects:

   1.   A new international terminal (26 gates). Total airport gates
        would increase from 80 to 103.

   2.   Air cargo development to accommodate cargo associated with
        both domestic and international passenger activity.

   3.   An airport Ground Transportation Center (GTC) served by the 
        airport Light Rail System (LRS) to reduce terminal area
        vehicle congestion.

   4.   Construction of the Airport Light Rail System to connect 
        BART and CalTrain to the airport terminals and other sectors
        of the airport. In addition, San Francisco International
        Airport (SFIA) is committed to fund up to $120 million  for 
        certain transportation improvements contained in an 
        agreement between SFIA, San Mateo County, and certain
        cities.

   5.   Additional on-airport passenger and employee parking 
        facilities, with emphasis on accommodating future airport 
        traffic by mass transit and high-occupancy vehicles (HOVs).

   6.   Incentives for passengers and employees to use HOVs for
        access to the airport. Incentives could include increased
        parking fees, and preferential treatment for public transit
        and HOVs on airport roadways and at the terminal curbs.

Chapter 1: Executive Summary                       September 9, 1994


   7.   Further reduction in airport noise levels below current
        exposure levels will occur by the year 2003 due to a
        complete transition to Stage 3 aircraft together with an 
        off-airport residential sound insulation program as 
        proposed by the airport.  Total area within the 65 CNEL
        (Community Noise Equivalent Level) noise contour will shrink
        from 14.9 square miles in 1990 to 7.6 square miles by the
        year 2010.  Total residential units within this noise
        contour will decrease from 5,210 in 1990 to 2,660 in the 
        year  2010. Support airport funding for the sound insulation
        program for nearby homes as specified  in  current
        agreements.

   8.   Annual runway capacity would be adequate to meet demand;
        however, peak hour demand would continue to exceed both
        IFR/VFR capacity. Depending on the growth in aircraft size 
        and passenger load factors, existing delay problems during 
        IFR/VFR weather may or may not be exacerbated. If growth in 
        passengers at SFO can be accommodated with nearly the same
        number of operations (as forecasted in the plan for 2010), 
        delay will not significantly increase. If these conditions
        are not realized, airlines may hold aircraft at the
        originating airport or flights may be delayed enroute by the
        air traffic control system. Overall, service could become
        less reliable during these weather conditions.

In addition, the RASP supports the following projects that are not
part of the SFO Airport Master Plan but which would support its
ground access and capacity enhancement programs:

   1.   A BART extension to SFO.

   2.   Initiate multiple actions to increase  VFR  and  IFR 
        capacity, including incentives for airlines to increase
        aircraft size, and to spread peak-period arrivals  and 
        departures, and consider capacity controls (such as slots)
        for California Corridor traffic. In addition, the following
        FAA initiatives? are supported in the Regional Airport 
        System Plan, but only to the extent that they can be 
        pursued without any compromises to airport or aircraft
        safety:

        a.   staggering aircraft for dependent converging arrivals
             so that air traffic controllers can verify instrument
             approach arrival spacing using a converging  runway 
             display aid;

Chapter 1: Executive Summary                       September 9, 1994


Oakland International (OAK)

   1.   Accommodate demand with existing runways; reassess  the 
        need for development of a second parallel air carrier runway
        when the airport reaches Stage 3 demand levels (10.6 million
        annual passengers).

   2.   Terminal expansion from 21 gates to 34 gates, as outlined in
        the 2002 Development Plan, with 40 gates required by the
        year 2010.

   3.   IFR capacity problems during peak hour would occur  sometime
        after Stage 2 demand levels are reached if no new air
        carrier runway is built.

   4.   Develop additional air cargo capacity according to the 2002
        Development Plan.

   5.   Improve the North Field runway system to serve as a reliever
        airfield if  South  Field  is unavailable.

   6.   Reduction in noise exposure compared to today's levels will
        occur. Total area within the 65 CNEL noise contour will
        shrink from 13.1 square miles in 1990 to between 4.4 and 5.2
        square miles in the year 2010. Total residential units
        within this noise contour will decrease from 590 units in
        1990 to 200 units in the year 2010.

   7.   Improve the terminal curbs and airport roadway system  to 
        accommodate future  traffic demands.  Provide additional 
        passenger and employee parking both on and off the airport.

   8.   Construct a fixed guideway transit system to connect Oakland 
        Airport with the Coliseum BART station. This system should
        be planned, designed, and developed consistent with the 2002
        Development Plan, and should be undertaken subject  to  the 
        approval of the parties to the MTC Regional Rail Extension
        Program.

   9.   Improve off-airport roadways to provide more convenient and
        predictable access for passengers, employees, air cargo
        traffic, and general aviation users.  These would include
        the 98th Avenue Improvement Project and the Airport Roadway
        Project. 

   10.  Consider high-speed ferry service between Oakland and San
        Francisco airports to provide greater passenger flight
        choices and scheduling convenience.

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


San Jose International (SJC)

   1.   Expand terminals as considered in Master Plan Alternative 6
        from 31 gates to up to 51 gates.

   2.   Improve ground access to San Jose Airport per Santa Clara 
        County T2010 Transportation Plan  recommendations, 
        including: Rte 87 highway improvements and a new   Skyport
        interchange; improve connections  between  airport 
        terminals  and  the Santa Clara  LRT (Light Rail Transit)
        system and CalTrain. Also, evaluate  the  feasibility  of 
        connecting Central Expressway and De La Cruz Boulevard  to 
        the  airport parking lots  for  airport users to bypass US-
        101 and to provide public transit more direct  access  from 
        the  Santa Clara CalTrain station; and identify locations
        within Santa Clara County with the  highest -concentration
        of airport users for public transit  and/or  private 
        service  options.  In addition, provide additional employee 
        and  passenger  parking  as  considered  in  Master Plan
        Alternative 6.

   3.   San Jose will have significant IFR airfield capacity 
        problems  due  to  the  presence  of general aviation
        activity at the airport.

   4.   Annual operations (air carrier and general aviation)  exceed 
        runway  capacity,  requiring that a portion of GA traffic be
        relocated to a reliever airport elsewhere in  Santa  Clara
        County. (Higher performance  general  aviation,  eg., 
        corporate,  etc.,  which  comprises some 25 percent of the
        general aviation airport activity at SJC, will remain).

   5.   At a minimum, approximately  210,000  annual  operations 
        and  600  based  aircraft  would need to be relocated to
        ensure adequate runway capacity for  air  carrier  use. 
        Providing reliever airports with  IFR  capacity  would 
        represent  the  most  optimum  form  of  new capacity.

   6.   Develop additional  air  cargo  facilities  as  considered 
        in  the  Airport  Master  Plan Alternative 6.

   7.   Develop airspace management strategies similar to those
        outlined above for SFO.

   8.   Total area within the 65 CNEL noise contour  will  decrease 
        from  11.8  square  miles  in 1990 to 3.0 square miles by
        the year 2010.  Total  residential  units  within  this 
        noise contour will decrease from 1,600 units in 1990 to 400
        units in  the  year  2010.  Continue neighborhood sound
        insulation program.

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


Sonoma County and Concord (Buchanan Field) - Air Carrier Service

     Preserve existing facilities and airline access agreements to
enable continuation of limited commercial service.

High-Speed Rail / Tiltrotor

   1.   High-speed rail may become  an  alternative  to  air 
        travel,  primarily  in  the  California Corridor.  Existing 
        air  passenger  traffic  in  this  corridor  (some  12 
        million   annual passengers) constitutes about 30 percent of
        the total Bay Area regional  air  travel  market. The
        passenger capacity provided by this rail system would  help 
        balance  air  travel  demand with Bay Area airport system
        capacity.

   2.   If a high-speed rail system is found to be feasible, support
        the  planning  for  conveniently located intermodal air
        passenger stations for the high speed rail system to tie
        into the  Bay Area's regional transit systems (BART and
        CalTrain).

   3.   While tiltrotor technology is still being discussed, its 
        future  application  to  commercial airline service is
        problematic. Nevertheless, the system  plan  supports  the 
        monitoring  of tiltrotor development.


Military Airfields and General Aviation Airports

     The following system plan actions refer to the four existing
military airfield facilities and specified general aviation
airports:

Travis AFB / New Air Carrier Airport

   1.   Based on the regional air passenger forecasts  prepared  for 
        this  plan,  the  region  could reach critical activity
        levels approaching peak-hour  airfield  capacity  between 
        the  years 2000 and 2005. Additional runways will  need  to 
        be  considered  at  existing  airports,  or Travis AFB or a
        new fourth air carrier airport will need to begin at  least 
        limited  service in that time frame in order to provide some
        air traffic relief for SFO, OAK, and SJC.

   2.   Determine the level of community and airline  interest  in 
        establishing  limited  commercial airline service (e.g.
        California Corridor) at Travis  AFB.  Also  examine  its 
        potential  as an IFR reliever airport  for  SFO  and  OAK 
        commercial  airline  flights  during  instrument conditions.

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


3.      If sufficient interest is demonstrated, update the Travis
        AFB Joint  Use  Feasibility  Study (1976) to address the
        following:

        a.   The listing and future Department of Defense (DOD)
             status of Travis
        b.   Potential effects on Travis' mission
        C.   Market analysis and refined air travel forecasts
        d.   Airfield and airspace capacity
        e.   Landside capacity
        f.   Local and regional access
        g.   Noise impacts and compatible land use
        h.   Operational issues related to military/civil joint use
        i.   Future property requirements (if any)
        j.   Generalized construction impacts
        k.   Airspace interactions with other airports (e.g.,
             Buchanan Field)
        l.   Identification and analysis of alternative methods for
             developing and operating  the civil portion of the
             airport
        M.   Military-civil airport joint use agreement

4.      The overall intent of the above mentioned actions is to
        explore  joint  use  of  the  Travis AFB facility, not to
        displace any existing or possible future military activity.

5.      As currently envisioned in the regional airport plan, a
        joint  use  airport  at  Travis  AFB would have an annual
        capacity to initially serve I million to 2 million  annual 
        passengers, and eventually up to 3  million  annual 
        passengers  or  more.  This  volume  of  passengers would be
        attainable well within the current airfield's operational 
        capacity  (approximately 340,000 operations) allowing for a
        continuation of the  current  level  of  annual  military
        operations (140,000) combined with an  initial  25,000 
        annual  civil  aircraft  operations. Even with 3 million
        annual passengers, the current  airfield  at  Travis  would 
        still  have significant unused annual capacity, and  could 
        accommodate  additional  military  or  civil operations.
        Transit access to other parts of  the  Bay  Area  for 
        Travis  passengers  could include the Capitol Corridor
        intercity rail  service,  "press  bus  service,  and 
        dedicated shuttle service to major North Bay communities.

6.      Preserve   and   strengthen   current   land   use  
        controls   necessary   for   compatible military/commercial
        operations.


7.      Skaggs Island has been proposed as a potential site for  a 
        new  air  carrier  airport.  The site, which lies along
        state Highway 37 near the north shore of  San  Pablo  Bay, 
        has  both opportunities and constraints. This Regional
        Airport  System  Plan  has  not  undertaken  an exhaustive
        study of the Skaggs Island site, nor has it attempted to
        locate  other  potential new airport sites.

1-20




MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


Moffett Field

   1.   The Naval Air Station at  Moffett  Field  has  been 
        declared  excess  by  the  Department  of Defense and has
        been taken over by NASA.

   2.   Other  non-NASA  tenants  using  the  airfield  will 
        continue   to   include   several   high technology  
        companies   performing   work   for   NASA,   the   Army,  
        Navy    and    National Reserves, the National Guard,  and 
        other  government  agencies.  The  use  of  Moffett  Field
        will likely be limited to these users in the foreseeable
        future.

   3.   As a reliever airport for San Jose, Moffett Field  does  not 
        appear  to  offer  any  enhanced instrument capability
        during IFR conditions because  of  airspace  conflicts 
        associated  with its proximity to San Jose airport.

   4.   Use of Moffett Field for a  broader  spectrum  of  aviation 
        activity,  including  GA,  should be left open for
        consideration in the future to the extent  that  it  does 
        not  significantly conflict with the nature or requirements
        of federal operations at Moffett.

   5.   Moffett Field is retained in this plan as a general aviation
        reliever airport.  As  such,  the BCDC should also retain
        the site's designation as an "airport priority use area"  in 
        its  San Francisco Bay Plan.  In  implementing  this 
        policy,  MTC  will  discourage  any  action  that would
        interfere with the airfield's ability to fulfill this role.

Alameda Naval Air Station (NAS)

   1.   As a result of  recent  Base  Closure  Commission  action, 
        Alameda  NAS  has  been  surplused by the Navy,  which  will 
        vacate  the  site  in  1997.  Although  it  offers  some 
        potential opportunities for civil aviation use, there are
        also constraints to its potential  development to provide
        passenger, air cargo, or general aviation service.

   2.   Alameda NAS has the potential to become a site for tiltrotor
        airline service if this  aircraft becomes viable for
        commercial use in the future, or as  a  heliport  for 
        corporate  or  other use.

   3.   Expanded use of Alameda NAS for  civilian  operation  could 
        create  airspace  conflicts  with Oakland due to the
        proximity of the two airfields.

Hamilton Army Air Field (AAF)

   1.   Hamilton  AAF  was  identified  in  the  1990  Regional 
        Airport  System  Plan  as  a  general aviation reliever
        airport, largely due to the instrument capabilities of the
        existing  runway,

1-21




MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


        which  could  augment  the  much-needed  IFR  capacity  of 
        the  Bay  Area  airport   system.  The use of Hamilton AAF
        for future general aviation  activity  has  been  envisioned 
        as  one strategy for diverting general aviation instrument 
        operations  away  from  overly  congested air carrier
        airports during the 7-12 percent of the year when the air
        carrier airport  system experiences  a  critical  capacity 
        shortage  during  poor  weather.  Substantial  investment
        would be needed to upgrade the airport  for  civilian  use 
        at  this  time,  considering  the limited infrastructure
        that actually is usable for airport purposes.

   2.   Hamilton  AAF  is  not  needed  to  provide  general 
        aviation  aircraft  parking  or  runway capacity for the 
        Bay  Area  general  aviation  system,  as  this  system 
        will  have  excess capacity in 2010.

   3.   Hamilton AAF has been proposed as an  alternative  to 
        further  development  of  Gnoss  Field by some aviation
        interests based on the belief that  the  airport  offers 
        superior  aviation capability; however, Marin County
        continues to invest in Gnoss Field.

   4.   Under current Department of Defense plans, the  airfield 
        will  be  surplused  in  1995,  and no entity has applied to
        use Hamilton as an airport.

   5.   There is active consideration of restoring the liked portion
        of the airfield to wetland.

   6.   Given the  above  considerations,  it  is  appropriate  to 
        consider  revising  the  Regional Airport  System  Plan, 
        and  consider  alternative  means  by  which   Hamilton  
        AAF   might benefit the regional airport system, which will
        continue to  experience  capacity  shortfalls in the future.
        In this context, this airport system plan proposes that if
        all or portions  of the airfield are returned to Bay or
        wetlands,  this  restored  area  should  be  'banked"  as
        mitigation for future enhancements to regional airport
        system capacity.  These enhancements  have  not  been 
        defined,  but  could  take  the  form  of  a  new  runway  
        at Oakland Airport, a new  airport  runway  in  the  North 
        Bay,  or  construction  of  a  crosswind runway at Gnoss
        Field for purposes of  safety.  Because  of  the  large 
        area  involved, the mitigation proposal would create more
        Bay or  wetland  than  would  likely  be  required  for the 
        actual  airport  improvement  projects.  Such  an   approach 
        would   require   further discussion  between  MTC,  BCDC, 
        the  U.S.  Army   Corps of  Engineers,   and   potential
        airport project sponsors, to define the nature of such an
        agreement.

Reid-Hillview Airport

     Preserve Reid-Hillview Airport as a general aviation reliever
airport or develop equivalent airport capacity elsewhere within
Santa Clara County.

MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


1.6     Plan Implementation

     This section lists actions that need to be taken for
implementation of the Regional Airport System Plan.  Some of these
actions can be undertaken by MTC, while others will require the
cooperation and actions of other agencies.  In addition, the
section includes recommended future planning studies that will
assist the region in implementing the system plan.

     To review MTC's responsibilities: MTC prepares a long-range
Regional Transportation Plan for the Bay Area that includes the
Regional Airport System Plan.  This airport system plan outlines
the long term development requirements of the general aviation and
air carrier airports in the region.  MTC is required by statute to
review and ensure that airport ground access projects that are
seeking federal and state funding assistance are consistent with
the Regional Transportation Plan before approving grants for these
funds.  MTC also programs funds for various highway and transit
projects through the federal Transportation Improvement Program
(TIP) after reviewing, scoring, and prioritizing projects submitted
by the county congestion management agencies (CMA s).  Also, for
general aviation airports, MTC assists the state in prioritizing
projects that are to be funded using federal and state aviation
funds.

     The Bay Area airport operators determine priority projects
necessary to implement their airport master plans, and generate
funding for these programs through airport revenues and federal and
state grants.  Noise abatement programs are also developed for each
airport under state law.

     Planning for ground access and public transportation to
airports is a joint responsibility of the airports, congestion
management agencies, local jurisdictions, Caltrans, transit
agencies, and MTC.

     The air traffic control system is operated by the FAA, which
manages the use of Bay Area airspace.

     The quantity, quality, and price of air service are determined
by the airlines.  Also, changes in airline fleet composition are
dictated by federal noise regulations and airline marketing and
service objectives.

     Land use development around airports is regulated by local
jurisdictions such as cities and counties, which consider county
Airport Land Use Commission (ALUC) plans in making land use
decisions.  The Bay Conservation and Development Commission has
permitting authority over airport plans which require fill in Bay
waters or wetlands located within the agency's areas of
jurisdiction, or which make a substantial change in the use of any
water, land, or structure within the agency's areas of
jurisdiction.  In addition, a BCDC permit would be required for any
change of use within the 100-foot shoreline band, any activity in a
priority use area as designated in the Bay Plan, as well as any Bay
fill for other purposes.

1-23




MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


     Various state and federal agencies could be involved if
airport development requires the taking of wetlands or has
potentially adverse impact on any endangered species.

     Within this context of planning and operating
responsibilities, those activities that are most appropriate and
relevant for MTC to undertake are listed below:

   1.   In cooperation with  the  air  carrier  airports,  refine 
        the  timing  of  future  airfield  and landside capacity
        improvements and costs.

   2.   Review airport master plans  and  project  funding 
        applications  for  consistency  with  the Regional Airport
        System Plan.

   3.   Reactivate the Bay  Area  Study  of  Aviation  Requirements 
        (BASAR)  as  a  forum  for  the three major air carrier
        airport  operators  to  evaluate  and  recommend  actions 
        that  will improve regional airspace capacity. Airspace and 
        airfield  capacity  will  be  the  critical constraints in
        the next 20 years and absent  improvements,  passenger  and 
        air  cargo  delay will  increase  to  unacceptable  levels. 
        BASAR  should  develop  its  own  work  scope  and obtain
        outside technical assistance to evaluate promising
        strategies  to  alleviate  airspace constraints in the
        region, and seek FAA funding for such analyses.

   4.   Determine the level of interest in proceeding with further
        planning  for  commercial  airline service at Travis AFB and
        explore funding options for such planning.

   5.   Program  federal  flexible  ISTEA  (Intermodal  Surface 
        Transportation  Efficiency  Act   of 1991)  funds  for  high 
        priority  ground  access  improvements   as   recommended  
        by   the airports and county  congestion  management 
        agencies.  Seek  separate  funding  for  airport ground
        access projects in future re-authorization bills from the
        Aviation Trust Fund.

   6.   Through  MTC's  programming  role  for  Bay  Area  general 
        aviation  airports,  ensure  that the critical airport
        infrastructure is adequately maintained, and the airport
        approach  zones and runway protection zones are protected
        through land acquisition where feasible.

   7.   Support  Airport  Land  Use  Commission  actions   that  
        protect   airports   from   further encroachment that would
        create noise, safety, or operational problems.

   8.   Continue to  participate  in  the  Northern  California 
        Airspace  Users  Working  Group  for general  aviation 
        airspace  issues;  consider  consolidation  of  BASAR  and  
        the   general aviation airport managers group.

   9.   Encourage the three  major  air  carrier  airports  to  work 
        with  the  appropriate  general aviation airports in their
        sectors of the region (Peninsula, South  Bay,  and  East 
        Bay)  to

1-24




MTC Regional Airport System Plan Update
Chapter 1: Executive Summary                       September 9, 1994


        ensure adequate future capacity to handle general aviation
        traffic displaced by the growth in air carrier and air cargo
        activity, including development of institutional
        arrangements to allow the air carrier airports to provide
        financial support for general aviation reliever airports;
        support the concept that all airports in Santa Clara County
        should be operated as a system.

   10.  Continue  to  maintain  airport  databases  necessary  for 
        future  planning,  such  as   the Regional Air Passenger
        Survey and Airport Activity and Noise Trends reports.

Recommended Future Planning Studies

MTC should support and participate in the following studies and
actions:

   1.   Reactivate  the  BASAR  as  described  above,  with  the 
        purpose  of   addressing   regional airspace constraints and
        developing consensus  on  proposed  solutions  among  the 
        Bay  Area airport operators, airlines, FAA, and other
        interested parties.

   2.   Update the MTC Air Passenger Survey in 1995, as a first step
        in  the  next  revision  of  the Regional Airport System
        Plan.  Consider initiating an Air Cargo Survey.

   3.   Update the regional airspace capacity plan for the air
        carrier airports  within  the  context of a single terminal

2      INTRODUCTION

     This chapter presents historical background about previous
airport system planning efforts in the San Francisco Bay Region;
defines the relationships between the Regional Airport System Plan
and other plans; describes the process used to develop this 1994
Regional Airport System Plan Update; and discusses national, state,
and regional aviation trends.  The trends discussion is important
to the process for two reasons.  First, it provides an
understanding of the forces which are shaping the aviation industry
and therefore the regional airport system.  Second, it provides
context for future regional airport system planning which goes
beyond mere forecasting.

2.1    Historical Background

     Efforts to provide a systematic regional perspective to
planning the region's airports were begun in the late 1960s, with
the original Regional Airport System Study (RASS) completed in
1972. In 1975 MTC received an FAA grant to update the 1972 Regional
Airport System Study.  The original regional airport plan, as it
came to be called, was updated using a two-phase process.  Phase I
consisted of a review of each of the underlying components of the
plan.

     The primary focus of Phase I was to identify overall regional
airport system planning issues, provide information, provoke
discussion, identify differing viewpoints, and aid the Regional
Airport Planning Committee (RAPC) in establishing a sound base of
information.  From that base, RAPC was charged with establishing
the relative importance of the issues in the Bay Region and making
recommendations to the Metropolitan Transportation Commission (MTC)
and Association of Bay Area Governments (ABAG) for future airport
plan revisions.

     Phase 2, begun in 1976, was a more detailed technical
analysis.  It also resulted in the production of a number of
separate reports and the North Bay Aviation Study.  These reports
were synthesized in three final summary documents published in
April, 1980: the Air Carrier Airports Final Report, the General
Aviation Airports Final Report, and the Summary Report.   That
update of the Regional Airport Plan (RAP) is referred to as the
1980 Update.  In addition to the items listed above, the 1980
Update included an Environmental Impact Report (EIR), which was
prepared in compliance with the California Environmental Quality
Act (CEQA).  The 1980 Update has served as the primary planning
document for directing the development of the regional airport
system since 1980.

     One of the more important resources for previous regional
airport system planning efforts has been the "Air Passenger
Survey." Since 1975 MTC has conducted air passenger surveys every
five years at San Francisco International, Metropolitan Oakland
International, and San Jose International Airport. . The survey is
used by MTC, airports, ABAG, and others for airport system
planning, individual airport master planning, development of new
air service, provision of improved regional ground access, and
planning and design of passenger facilities.

2.2    Relationships Between the RASP and Other Plans

     The Regional Airport System Plan (RASP) is one of several
planning documents which address airport system development in the
San Francisco region.  Other plans include MTC's Regional
Transportation Plan (RTP), the California Aviation System Plan
(CASP), the FAA's National Plan for Integrated Airport Systems
(NPIAS), and the individual master plans for airports in the
region.

Regional Transportation Plan (RTP)

     The Regional Airport System Plan (RASP) is an appendix to the
Regional Transportation Plan (RTP), as is the Regional Seaport
Plan.  The RTP represents the regional transportation policy and
investment perspective of MTC.  The RTP includes a Policy Element,
which establishes regional goals and objectives; an Action Element,
which defines specific transportation improvements and programs;
and a Financial Element, which identifies the funding for the
Action Element.

     The RTP is a state and federally mandated document designed to
ensure that transportation improvements in the Bay Area are planned
with a comprehensive view of the transportation system, land use
plans, and environmental issues.  The RTP is adopted by the
Commission and revised every year as appropriate.

     California Aviation System Plan (CASP)

     The RASP has a much less structured relationship to the CASP
than to the RTP.  The CASP is prepared by Caltrans with input from
the FAA, regional airport planning agencies (such as MTC),
individual airports, and a number of other public agencies, user
groups, and the general public.  The MTC Regional Airport System
Plan is not adopted by the State, nor does it become a formal,
integral part of the CASP.  The RASP and CASP need to be
consistent.  Their authors (MTC/ABAG and Caltrans) need to have an
ongoing dialogue regarding airport roles, overall airport system
development, airport master planning, airport improvement projects,
airspace issues, capital improvement programming, airport impacts,
and a number of other airport planning issues.  To meet these
objectives, the RAPC has had continuous Caltrans representation
throughout the RASP planning process.  Elements of the CASP have
been used as resources in preparing the RASP.  In turn, the RASP
will be used by Caltrans in its continuing program of state
aviation system planning.

     National Plan of Integrated Airport Systems (NPIAS)

     Section,504(a) of the Airport and Airway Improvement Act of
1982 (P.L. 97-248) requires the Secretary of Transportation to
publish a national plan for the development of public-use airports
in the United States.  The NPIAS is that plan.  It draws upon
local, regional, and state planning

studies, including the RASP.  Nearly all the region's public use
airports are included in the NPIAS.  SFO, OAK, SJC, CCR, and ST'S
are designated as *primary and commercial service' airports.  San
Carlos, Half Moon Bay, and Gnoss Field are designated relievers for
SFO; Concord, Hayward, Napa County, and Livermore are relievers for
OAK; and Palo Alto, Reid Hillview, and South County are relievers
for SJC.  The other airports are designated as general aviation
airports.

Individual Airport Master Plans

     Numerous individual airport master plans have been used as
resources during the preparation of the RASP.  These plans have
provided valuable information regarding physical facilities,
policies, forecasting, airport-specific development plans,
environmental impacts, traffic and ground access issues, and
landside and arced capacity.  During the course of the RASP update,
the master plans for SFO, OAK, and SJC were in the process of being
updated, thus providing an opportunity for interaction during the
numerous planning efforts.  San Francisco's master plan update was
approved in November 1992.  As of early 1994 San Jose is continuing
toward a completion date in late 1995, and the plan for Oakland is
nearing completion after being redefined as a "10-year Airport
Development Program."

2.3     Planning Process

     Work on the current Regional Airport System Plan Update began
in 1991.  As with previous planning efforts, the process was
directed by MTC staff with ongoing oversight by the RAPC.  An
airport consulting team provided the technical analysis under the
direction of both MTC staff and RAPC.  This study was funded by
grants from the U.S. Federal Aviation Administration (FAA).

     The RASP planning process involved preparation of a set of
goals and objectives; an airport system inventory and capacity
assessment; aviation forecasts; definition and analysis of airport 
system alternatives; selection of a system alternative; preparation
of the new system plan, including capital improvements program and
recommendations for future planning studies and ongoing planning
activities; and completion of an environmental study.  Two parallel
tracks were taken for the RASP: one for the air carrier airport
system and a second for the general aviation airport system.  Prior
to beginning work on the actual system plan, nine focus groups were
formed to help the planning team identify critical issues, collect
input about these issues, and provide overall direction to the
planning process.

Focus Groups

     One of the first steps in the current planning process was to
solicit a broad range of input from around the region on a wide
variety of topics related to aviation.  This took the form of a
series of 'focus groups" which met in late 1990.  The results of
the focus groups are presented in Appendix B of this document. 
Nine groups were formed as follows:

                  Focus   Group   1:  Airport Management
                  Focus   Group   2:  Government and Civic Leaders
                  Focus   Group   3:  Bay Area Frequent Flyers
                  Focus   Group   4:  Residents Near Airports
                  Focus   Group   5:  Pilots
                  Focus   Group   6:  Environmental Activists and
                                      Authorities
                  Focus   Group   7:  South Bay Frequent Flyers and
                                      Residents
                  Focus   Group   8:  Area Business Leaders
                  Focus   Group   9:  Airline Representatives

Summary of Key Findings

     The following summary was taken from the Focus Group Results
Report published in February 1991, and reproduced in full as
Appendix B of this document.

             Focus groups with a wide range of Bay Area
        constituencies with an interest in the Regional Airport
        System revealed the following findings:

             -    There was widespread demand for information and
                  strong action - and little awareness of the 1980
                  Regional Airport Plan (RAP).

             -    MTC and the RAP update should anticipate increases
                  in demand, and decide whether or not to facilitate
                  redistribution or reallocation of demand. 
                  Consumers say they would make greater use of OAK
                  and SJC if it were more convenient and affordable.

              -   Ground access is perceived to be the most critical
                  issue facing the system in the near term. 
                  Specifically, this includes Improved access to
                  airports and improved intermodal connections.

             -    There is widespread recognition of the need and
                  desirability of mining environmental impacts, also
                  acceptance that this will constrain growth.  But
                  no clear priorities or consensus on trade-offs is
                  apparent.

   *    There is broad agreement on the 'vital role' of GA  and 
        Reliever  Airports,  but little positive action is expected:

                  *    Preservation is  the  real  issue  (not
                       facility  enhancement).  The  importance  of
                       preserving facilities will be even greater in 
                       the future,  as  system  capacity falls
                       behind growing demand.

                       of the  major  airports.  Yet there Is strong
                       political opposition locally and little
                       expectation  for  positive action.

   *    People generally perceive the airports to be a key asset to
        the region, contributing to both the economy and the overall
        quality of life.  And they want action to preserve these
        benefits.


     Regional Airport Planning Committee (RAPC)

     The Regional Airport Planning Committee provided continuous
review throughout the planning process.  Approximately 18 RAPC
meetings were held between January 1991 and the completion of the
plan in early 1994.  A list of RAPC members who participated in
this process is included as Appendix C at the end of this plan. 
Also included in Appendix C is a list of the MTC/ABAG staff
participants and the consulting team.


2.4     National and State Aviation Trends

     In the past 10 years the worldwide aviation industry has
undergone unprecedented growth and change.  The growth has occurred
in nearly all sectors: passenger traffic, air cargo volumes,
general aviation activity, airline route structure, investment in
new aircraft, and investment in airport infrastructure.  The change
has come in many forms: the end of airline regulation; the
emergence of the hub and spoke route structure and development of
superhub airports to support these routes; the emergence of the
regional airlines; the rise and fall of several major airlines;
banner years of airline profits mixed with years marked by
disastrous losses; the approval of the Passenger Facility Charge
('PFC'); the phaseout of Stage B aircraft; the emergence of
environmental concerns; privatization; and a growing uncertainty
about what the future will bring.

Chapter 2: Introduction                            September 9, 1994


     Successful completion of a long range regional airport system
plan requires that the planning effort be formulated around a
thorough understanding of the forces that cause these changes in
the aviation industry.  With this knowledge the planning effort can
produce achievable goals and objectives and focus on issues which
must be addressed.  The following are anticipated trends in
aviation which will have some affect on the future of the region. 
Although some may be minor all must be considered.

1.      Globalization of air travel/growth of international segment.

     The international segment, while currently a small proportion
of air passenger traffic, will grow much more rapidly than the
domestic segment, eventually rivaling it in size.  The "open skies'
policy toward international trade and travel (North American Free
Trade Agreement -"NAFTA" -- is a good example) has created the
potential for new opportunities for U.S. airports to participate in
the globalization of the aviation industry.  This will have
important implications for the region, which is poised to capture a
large share of the growing international travel market.  In the
future, international air carriers serving Bay Area airports will
increasingly provide 'through" flights which will connect the U.S.
with Latin America, Canada, Asia, and Europe, using Bay Area
airports as international gateways.  A critical function of the
regional airport system (although this role may primarily be filled
by SFO) in the coming decades will therefore be to provide for the
integration of international and domestic passenger facilities
which create a 'seamless" process for moving passengers and cargo
through the airports.

2.      Increased emphasis and concern for environmental quality.

     Within the last 10 years environmental concerns have
increased.  Airport operators are regularly required to address a
wide range of community issues such as airport noise, air quality,
traffic congestion, water quality, economic impact, wildlife and
wetlands.  Airport operators are finding it necessary to undertake
lengthy and detailed environmental studies including major citizen
involvement elements as a prerequisite to airport growth and
development.  This trend is destined to continue in the future, and
will create major changes in the airport planning process
nationwide.

3.      Continued growth of regional carriers.

     The market for fast, safe, convenient, and comfortable air
travel in the range of 200-500 miles is still growing.  In the
coming years this market will spawn additional growth in regional
carriers using the latest aircraft technology, such as the Canadair
Regional Jet (RJ), BAe 146 series, the BAe ATP, the Brasilia, and
the Fokker 50 and 100.  The airlines, however, are still looking
for new aircraft which can be operated at less cost on these thin
routes.  The airlines say there are currently no acceptable 60-80
seat jet aircraft which offer reasonable passenger comfort and
which can be economically operated in the 2-3 hour range.  Regional
carriers will be tightly allied with the national carriers in
providing connecting service and code-sharing

2-6

agreements. (Code sharing is a term for affiliations between
commuter/regional airlines and major air carrier airlines who share
computer reservation systems, making it easier to book passengers
on connecting flights).

4.      New non-stop service will emerge to augment multi-stop
        routes through hubs in major markets.

     As the nation's superhubs reach saturation, the airlines will
turn to scheduling flights on direct long-haul routes between major
markets where there is sufficient passenger demand (and airline
profit) for these point-to-point routes.  As an example, United may
currently provide eight daily flights from Seattle to San Francisco
and 15 daily flights from San Francisco to Los Angeles, future
passenger demand for non-stop service between Seattle and Los
Angeles may make it feasible for United to add several new daily
non-stops between Seattle and Los Angeles, eliminating the
intermediate stop in San Francisco.  From a passenger standpoint
these new nonstop routes (which would overfly SFO) would provide
improved service, greater convenience, and reduced travel time. 
From an airport  and airline industry standpoint, the non-stop
routes would provide some relief for overtaxed capacity at many
existing large hub airports and result in some reduction in system
wide delays.  In San Francisco, this would provide additional
operations capacity, allowing United (and other carriers) to
enhance existing service out of SFO and/or add new spoke routes to
additional markets such as Reno, Salt Lake City, Fresno, Medford,
and Boise.

     In large metropolitan areas such as Los Angeles, the airlines
will provide more service to outlying airports, such as Long Beach,
Ontario, Burbank, and Orange County to avoid the congestion at LAX. 
Such routing will also enable the airlines to take advantage of the
currently under utilized airfield capacity in these locations,
provide a variety of destinations to passengers, reduce airport
access travel times, and further reduce congestion and delay at the
major hubs.  The local equivalent, of course, are Oakland and San
Jose providing relief for San Francisco.

    5.  Cargo growth will continue but aviation will remain
        primarily a passenger aircraft industry.

     With the economic pressures on the air cargo sector, it will
become more tailored to manufacturers' and retailers' needs for
just-in-time delivery, damage control, express delivery advantage,
and split location production.  The San Francisco-Oakland-San Jose
region, with its sea-air links, will retain a strong position in
the shipping industry.  Historically, the bulk of air cargo has
been carried in the bellies of passenger aircraft, rather than on
all-cargo aircraft.  Oakland is an exception to this trend, with
most of its cargo being composed of overnight express mail carried
by non-passenger all cargo aircraft.  These trends are anticipated
to continue indefinitely.  In addition, since the concept of
developing large air cargo airports does not appear to be feasible,
most air cargo will be processed at existing multi-use airport s.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


6.      Passenger traffic will continue to increase to more than
        double current levels before the OS' curve maturation of the
        world-wide market takes effect.

     It is inevitable that the worldwide aviation market will
eventually reach maturity, after which time overall growth is
expected to level off.  Until that time, passenger and air cargo
activity will continue to grow, although at declining growth rates
over time.  Developing nations will contribute a large share of the
remaining growth in the worldwide passenger travel market before it
matures.

7.      New technology is not the solution to the nation's airport
        and airspace capacity dilemma.

     Although many new technologies are being developed, few will
have any significant impact within- the next 20 years.  While some
technological developments are being discussed, such as 1,000-seat
airplanes, a high-speed civilian transport (HSCT) for long haul
transoceanic routes, tiltrotor aircraft for short routes; and
improvements in avionics and air traffic control, the bulk of
current technological research is related to refining current
aircraft designs.  In sum, the most we can expect from these
efforts will likely be larger versions of today's aircraft with
more fuel efficient, quieter engines.  Examples include
technological enhancements and stretched versions of the Boeing
747, 757, 767, and 777; the MD-11 and MD-12; and the Airbus A330
and A340 airframes.

     One major reason for this is the cost and overall feasibility
of research and development required to bring truly new technology
into production.  Two major considerations in assessing the
feasibility of new technology are the strength of the general
economy in supporting the development of prototypes and their
implementation to full-scale production, and the desire of the
aviation industry to fund such technology in light of their need to
be profitable.  It is possible, however, that a new set of aircraft
noise standards will emerge in the next 20 years, forcing the air
transportation industry to develop even quieter aircraft.  In
addition, rising fuel and other operating costs combined with
potential fuel shortages, and the need for cleaner running engines,
could increase the industry pressure to develop more fuel efficient
and less polluting engines.

8.      Creative new funding and development approaches must be
        found.

     As with most other public infrastructure nationwide, airports
are experiencing a gap between the level of funds available and the
amount of funds needed for airport development, operation, and
maintenance.  New methods of financing airport development,
operation, and maintenance are being created.  These include
increases in locally-generated funding, user fees such as passenger
facility charges (PFCs), public-private partnerships, and a growing
movement toward privatization.  The most notable current example of
this trend is private involvement in terminal development at
Toronto.

Chapter 2: Introduction                            September 9, 1994


9.      Contrary to some opinion, the continued development and
        expansion of the worldwide telecommunication industry may
        actually increase the demand for air travel.

     Some believe the massive growth in the worldwide
telecommunication industry will cause a concurrent reduction in air
travel, citing the decline of the nation's passenger railroads
after construction of the interstate highway system and the
emergence of fast and relatively inexpensive air transportation. 
Telecommunications advancements are increasing the total level on
worldwide communication between people and nations, breaking down
trade and cultural barriers, and causing an increasing demand for
travel, particularly at the international level.

10.     The overall health of the U.S. and global economies, and
        particularly the  health  of  the airline industry, may have
        an important impact on  future  airport  development 
        programs.

     Airport sponsors, while in need of increasing capacity, will
need to be particularly sensitive to the economic health of the
airlines serving them.  The overall poor health of the airline
industry in recent years has caused the airlines to be increasingly
concerned about airport capital programs which place major
financial burdens on them.  Already under significant financial
pressure from fare wars, competition with airlines operating under
Chapter 11 protection, and requirements to replace older noisier
aircraft with stage 3 airplanes, the airlines are objecting to
large new airport capital investment programs.  Airports, in
developing their master plans and subsequent capital improvement
programs, must be increasingly sensitive to the potential financial
impacts those programs may have on air carriers.  A related concern
for airport planning is the affect that the airlines' poor economic
health is having on aircraft orders.  With the recent cancellation
of large numbers of aircraft orders and options, the future airline
fleet composition is uncertain, making it difficult for airports to
know how to meet demand.  This complicates the assessment of runway
capacity and noise trends.

11.     The intermodal aspects of airport operation development will
        continue  to  draw  attention and demand new methods to
        resolve airport access issues.

     Surface access to airports has become a major issue is our
nation's urban areas.  Although much attention has been spent
studying airfield and passenger terminal capacity issues, the issue
of how to get passengers and cargo to and from the airport
efficiently has only recently reached the public agenda.  In large
urban areas where many of the nation's busiest airports are
located, saturated freeways and surface streets are making airport 
access increasingly difficult.  As this congestion increases, and
as the public's collective consciousness evolves toward accepting
various forms of public transit, new and innovative ideas are
emerging.  More and more airports are seeing the wisdom of planning
for multi-modal access.  examples include the planned BART
extension to SFO and the proposed AG (Automated Gaiety System)
between BART and the Oakland airport.  In planning for the regional
airport system of the future, regional ground transportation links
will take on increasing importance.

2.5    Regional Aviation Trends

     During the past 20 to 30 years the San Francisco region has
seen significant changes in the aviation system.  Between 1960 and
1990 the region's population grew from 3.6 to about six million. 
During this same time frame the regional air passenger activity
grew from five million annual passengers to nearly 43 million, an
eight-fold increase.  In 1960 San Francisco had established its
regional dominance, capturing 92 percent on the total regional
passenger market.  At that time Oakland had captured 7 percent, and
San Jose had I percent of the market.  Between 1960 and 1970
Oakland and San Jose began to increase their shares of the regional
market.  By 1970 their shares had grown to 12 and 9 percent
respectively, leaving San Francisco with 79 percent.  During the
1970s San Francisco again experienced strong growth, and increased
its market share from 79 to 80 percent.  From 1970 to 1980
Oakland's traffic slowed while San Jose grew strongly, and by 1980
San Jose (with II percent) had surpassed Oakland (9 percent).

     Between 1980 and 1990 additional changes occurred.  With the
strong growth in overall passenger traffic and the emergence of
regional carriers, Concord and Sonoma County established scheduled
passenger service in 1986 and 1985, respectively.  By 1990 Oakland
had re-established its former market share at 12 percent.  San
Jose's passenger traffic continued to grow, fueled by the success
of "Silicon Valley" businesses and American Airlines' hub
operation, bringing its share of regional traffic to 16 percent. 
San Francisco continued to grow, but by 1990 its market share
slipped to 71 percent.

     A review of regional urban development, regional
transportation system development, and airport system development
over the past three decades reveals a number of significant trends:

Passenger Trends

     Aside from temporary, localized plateaus in traffic growth,
all airports have seen strong and continuous growth in the past 30
years.  Regional population growth has been equally consistent
throughout the period.  In addition, the regional economy had been
historically strong until the early 1990s, when the sluggishness of
the national economy and the drop in activity in "Silicon Valley"
began to cause a regional economic downturn, which continues.

     While the regional surface transportation system has seen
significant development and capacity expansion, traffic has grown
and congestion has continued to increase.  This has been caused by
numerous factors, including the geography and urban development
patterns-of the region; significant population and employment
growth; the presence of major physical constraints to
transportation system development (such as the Bay); the cost of
transportation system improvements; and a wide range of
environmental and political constraints.

Chapter 2: Introduction                            September 9, 1994


     Because of the problems caused by airport  delay, congestion
of the regional ground transportation system, and the increasing
difficulty getting to the airports (particularly San Francisco),
the region's air passengers have begun to look for airport 
alternatives.  Airlines have begun to recognize the demand for more
convenient air service, and have established major air carrier
operations (some with low cost fares) at Oakland and San Jose.

     San Francisco has established its dominance in the
international market, and in 1990 captured 95 percent of the
region's international passenger activity.

Air Cargo Trends

     Regional air cargo activity has been consistent with national
and worldwide air cargo trends with very strong growth over the
past 10 years.  From 1980 to 1990 total regional cargo volumes
increased from 200,000 enplaned tons to over 480,000 enplaned tons,
an average annual compound growth rate of over 9 percent. 
Nationally, the annual growth for this same time period was also
about 9 percent, while worldwide air cargo (freight and mail)
volumes have grown by an average annual rate of 8 percent for the
20 years between 1970 and 1990.

 Locally, San Francisco has seen strong air cargo growth, boosted
by its increasing role in the international marketplace.  Between
1980 and 1990 air cargo activity at SFO grew by a total of 64
percent.  San Francisco's air cargo has historically been a mixture
of traditional cargo, airline belly cargo, and overnight express
cargo.  Oakland has created its niche in the overnight express
cargo market with the development of the Federal Express Metroplex,
which has seen meteoric growth (4600 percent) from 1980 to 1990. 
Since 1990 Oakland has continued to see very strong growth in air
cargo activity, giving rise to an adjusted cargo forecast for
Oakland (see chapter 5: Aviation Demand Forecast).  Although
Oakland has a mix of traditional, airline belly, and express cargo,
the vast majority of its cargo is overnight express cargo carried
by all cargo carriers such as Federal Express and UPS.  San Jose
also saw strong cargo growth in the 1980's, with an eight-fold
increase, most of which was carried by airlines as belly cargo.

General Aviation Trends

     In the past 10 years the general aviation sector of the
aviation industry, both locally and nationally, has experienced a
general decline.  Rising purchase and operating costs, the lack of
new GA aircraft production, and increasing airspace congestion and
complexity have combined to cause a long-term decline in most
general aviation activity (primarily recreational and discretionary
flying).  The one area of GA that has continued to grow is
corporate GA, which appears to be less sensitive to the factors
which have caused the general decline.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


Several other regional general aviation trends over the past 10
years are notable:

   1.   There  has  been  a  steady  decline   in   the   number  
        of   student,   private, and commercial pilots.

   2.   Between 1986 and 1990  the  number  of   commercial  pilots  
        has  shown   a  slight   growth trend.

   3.   Since  1983  the  number   of   airline   transport  
        certificates   for   pilots  ages   25-34   has increased. 
        As  the  existing   active  commercial pilot  population  
        ages   and   retires,   the market  for new  pilots will
        create  a  market  for  additional  pilot training activity. 
        This demand is expected to establish a lower boundary for
        general aviation pilot training activity.

   4.   The  number  of  regional  GA  based  aircraft  has 
        stagnated  during  the  past  10   years,   while the 
        number  of  total  operations  and  total  hours  flown 
        have  both  declined.   As   a   result, aircraft 
        utilization  (measured  in  total  hours  flown  per  year 
        and  in  number  of   operations per  based  aircraft)  has 
        declined.  This  trend  is  not  just  regional,  but 
        statewide.  As   an example,  GA  aircraft  utilization  for 
        the  state  of  California  declined  from  200  hours   per
        year in 1980 to about 150 hours per year in 1988.

   5.   Since  1980  several  public  use  airports  have  been 
        lost  to  public   use   or   closed.   These include  Santa 
        Rosa  Air  Center,   Fremont,   Antioch,   Morgan   Hill,  
        Vacaville,   Vaca   Dixon, and Smith  Ranch.  In  addition, 
        the  region's  military  airfields  have  seen  pressure  to 
        close, with  Hamilton  and  Moffett  Field,  and   Alameda  
        NAS   all   being   declared   "surplus/excess".

   6.   As  a  result  of  past  closures  and  the  continued 
        possibility  of  additional  GA  or   military facility 
        closures,  one  of  the  important  issues  facing  the 
        general   aviation   and   military communities  is  the 
        preservation  of  existing  airport  facilities.  As 
        activity   at   the three major air carrier  airports 
        increases,  there  will  be  increasing  pressure  for 
        general  aviation activity  at  those  airports  to 
        relocate  to  other  less  congested  GA  airports.  The  
        region's general  aviation  reliever  airport  system  will 
        therefore  become  even  more  important  in   the future.


   7.   Planning  for  the   region's   general   aviation  
        airports   will   likely   need   to   focus   on
        preservation  of  existing  facilities,  compatible  land  
        use   planning,   protection   of   runway approaches, 
        airspace  concerns,  noise  abatement,   airport   facility  
        maintenance,   safety   and security  issues,  the  need 
        for  new  hangars,  storm water  runoff,  and  the  shift  
        in   activity growth from recreational users to corporate
        users.

3  GOALS & OBJECTIVES


   A.   Improve Regional Access to Air Service

   1.   Provide air passenger facilities which will be convenient in 
        terms  of  their  location  and accessibility for regional
        air travelers and airport employees.
   2.   Provide general aviation facilities which will be convenient
        in terms of their  location  and accessibility for both
        business and non-business aircraft owners
   3.   Provide  improved  transit  and  highway  connections  to 
        air carrier  and   general   aviation airports to enable air
        travelers, airport employees, cargo shippers, and other
        airport  users to quickly and reliably make ground access
        trips to and from Bay Area airports

   B.   Improve System Safety and Efficiency

   1.   Support measures to increase runway and airspace utilization 
        as  a  means  to  maximize  the use of existing airfield 
        capacity  (e.g.,  larger  aircraft,  higher  load  factors, 
        better scheduling of airline flights to  reduce  runway 
        overload,  and  technological  improvements in the air
        navigation system)
   2.   Ensure that airport system improvements do not compromise
        air safety
   3.   Ensure that runways, taxiways, and other  critical  airport 
        operating  facilities  are  well maintained
   4.   Provide facilities on the airports that improve efficiency
        of  operation  for  airport  users (e.g., expanded terminals
        and additional gates, internal  airport  circulation  roads, 
        modem cargo facilities, new hangar facilities for general
        aviation, etc.)

   C.   Promote Equity for System Improvements

   1.   Seek an equitable distribution of airport system benefits
        (access to  air  service  in  terms of destinations,
        frequency, fares, etc.) and impacts Local  traffic 
        congestion,  noise,  air pollution, and other land use
        impacts)
   2.   Develop an airport access system  which  provides  efficient 
        and  affordable  ground  access from all parts of the Bay
        Area
   3.   Provide an equitable decision process in developing the
        Regional Airport Plan

   D.   Sensitive to the Environment

   1.   Minimize regional (and, to the extent possible, local)
        community noise exposure
   2.   Minimize air pollution from auto and aircraft activity
   3.   Minimize energy consumption from auto and aircraft activity
   4.   For projects requiring Bay fill or taking of wetlands, seek 
        solutions  which  result  in  no net impact and, further,
        which enhance these resources
   5.   Ensure safety for people on the ground

   E.   Promote Economic Vitality

   1.   Support air service improvements in domestic  and 
        international  markets  as  a  means  to stimulate commerce
        (business and tourism)
   2.   Support airport improvements consistent with the regional
        plan as a means to  foster  local economic vitality for
        communities around airports
   3.   Reduce runway and airspace delays which generate airline 
        costs  and  lead  to  higher  air fares for air passengers
        and cargo shippers
   4.   Maintain land use  compatibility  around  airports  to 
        avoid  adverse  impacts  on  future airport operational
        capabilities

4  INVENTORY AND CAPABILITY ASSESSMENT

   4.1     INTRODUCTION

     This chapter documents the existing physical, operational,
environmental, and policy conditions for each airport in the
system, and for the system as a whole.  In addition, the chapter
presents information on the constraints and capabilities of the
airports, and the airport system.  These constraints and
capabilities directly affect the system's ability to meet current
and future aviation demand in the region.

     Physical conditions data includes such items as airport
ownership, location, and size; number and length of runways;
airport classification; number and  of aircraft based at the
airport; amount of passenger terminal facilities; and whether an
air traffic control tower is present.  Operational conditions data
includes items such as total annual and peak-hour operations';
operations split between air carrier, commuter, and general
aviation; annual passenger enplanements; and annual air cargo
volume.  Environmental conditions data includes general information
about the natural and human environment near each airport,
including such items as noise-sensitive land uses, wildlife
habitat, and wetlands.  Policy conditions information includes
current airport master plan, capital improvement program, and other
policy opportunities and constraints that affect the development
and operation of individual airports and the airport system as a
whole.

     Finally, the chapter presents information about the technical
constraints and capabilities that affect the airport system.  These
include items such as landside (vehicular access and parking,
terminal, and related facilities) and arced (aircraft parking,
taxiways, and runways) capacity and regional airspace.

     The detailed airport system inventory includes all public-use
and military airports in the region.  Private-use airfields are
also included, but in less detail, primarily because there is
considerably less information available about private-use airport
facilities than public-use airports.  This inventory also contains
information about public-use and military airports that have been
closed or are inactive, such as Hamilton Field and Fremont Airport. 
Although currently closed or inactive, these facilities have been
considered in planning for the regional aviation system.

     This chapter catalogs current data (in most cases 1990) on the
physical facilities and operations at the airports under
consideration.  Historic data on operations, passengers, air cargo,
and based aircraft for the period 1980 through 1990 is included in
Chapter 5 (Historical Airport Data).  Those data were developed to
document trends and to assist in the preparation of the aviation
system forecasts (see Chapter 5).  The system will first be
characterized, with reference made to the 1980 MTC System Plan to
identify major changes in the past decade.  A look at the
facilities and operations for the year 1990, including a capacity
analysis, is then presented to give an idea of what there is to
work with today, and what the immediate areas of concern are.  This
information will be the basis for alternatives development and
analysis.

Chapter 2: Introduction                            September 9, 1994


     Much of the information used in this inventory was derived
from The California Aviation System Plan (Element 1: Inventory,
published August 1990), which is presently being updated by the
California Department of Transportation Division of Aeronautics. 
Other data sources included the most recent individual airport 
master plans and capital improvement programs, current and historic
FAA Airport Master Records (FAA 5010 forms), FAA activity
statistics, and through direct contact with the individual
airports.  The most current information available has been used. 
In most cases this represents conditions in the year 1990.

     A survey of planning documents provided by the airport
operators as well as field visits provided first-hand information
about site-specific conditions which could impact future capacity. 
The inventory data were then verified by a follow-up survey, which
gave the airports an opportunity to be involved in the MTC planning
process.

4.2    THE REGIONAL ART SYSTEM

     The regional airport system includes some 26 public-use civil
airports, 4 military airports, 2 special-use airports, and 21
private-user facilities.  Of the 26 public-use airports there are 5
with commercial airline service, while the other 21 are general
aviation airports.  There are 12 public-use airports which
currently have helicopter activities and/or services.  These
include all 5 of the commercial service airports and 7 general
aviation airports.  Following is a list of all these airports in
the airport system.  Airports with FAA Air Traffic Control towers
are indicated by an asterisk (*).  Facilities serving primarily as
gliderports are designated with a "G." Please refer to Exhibit 4.17
for the complete airport system data inventory.

     There are 4 military airfields in the 9-county area, which are
publicly owned but have restricted access.  Travis AFB had a joint-
use agreement with Solano County which provided for commercial
airline service, but that agreement expired in 1992.  Private-use
airports are acknowledged because there may be the option for
public use and/or acquisition.  An example of such an acquisition
is in Clark County, Nevada, where the County acquired a closed
private use airport which now serves as a reliever for McCarran
International Airport in Las Vegas.

     Helicopter/rotorcraft facilities are part of the aviation
system, and are projected by national trends to be an increasingly
important component of the national air transportation system in
the future.  There are two categories of these facilities: (1)
heliports, which are areas with full services available, and (2)
helistops, which are pads strictly for takeoffs and landings. 
There are currently no publicly owned, public-use heliports in the
study region.  The downtown San Francisco heliport (referred to
above as Crissy Heliport), located on the waterfront, is closed. 
Only four of the public-use airports have designated helicopter
takeoff-landing areas.  A number of private heliports and helistops
dot the region.  These facilities are owned and used by various
groups including hospitals, corporations, and the media.  In
addition, there are several publicly owned police and military
rotorcraft facilities, which have limited access by the public.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


     The one independent seaplane base in the region, Commodore
Center in Marin County, changed from a public-use facility to a
private facility at the end of March 199 1. It is currently used
for training and sightseeing.  A second seaplane facility is
planned adjacent to San Francisco International Airport.

     More than ten years have passed since the last MTC Regional
Airport Plan revision, and many changes have occurred in the system
since that time.  The number of facilities has increased.  Some
have shifted in  of ownership and category of use.  The 1980 plan
recognized 3 commercial airports, 17 public-use general aviation
airports, and 11 private general aviation airfields (discounting
small airstrips), and four military airfields.         Since 1980
scheduled passenger service has also been provided at two general
aviation airports: Sonoma County and Buchanan Field.  There has
been a reduction in the number of public helicopter landing areas
located at fixed-wing facilities, while the region has seen a net
increase in the number of medical heliports and helistops.  The
same four military facilities remain today.

4.3    AIRPORT FACILITIES

     This section is devoted to discussion of the physical
facilities at each airport, and is divided into the following
groups: commercial service airports; general aviation airports;
military airports; and heliports.  The location of public use
airports in the nine county system is shown in Exhibit 4. 1. The
Public Use Airports Inventory in Exhibit 4.17 lists a number of
facility characteristics for the public-use airports in the system. 
This includes the airport size in acres, airport class, number of
runways, length of the longest runway, instrument approach, whether
there is an air traffic control tower, and the rotorcraft
facilities on site.  The facilities allowing for helicopter
activity have been categorized as such.  Those with designated
takeoff/touchdown landing pads have the number of helicopter
takeoff/landing areas recorded.  Those with helicopter operations
but no designated helicopter landing areas are indicated by the
term "ops" under the heading of 'Rotorcraft Facilities'.  Where
there are helicopters based at the airport, they are listed as such
in the based aircraft section of Exhibit 4.17. Characteristics of
the various airport facilities are illustrated in Exhibits 4.2 -
4.5, including towered airports, helicopter facilities, airports
with air cargo traffic, and special use airports (primarily
gliderports).

     Ground access to the airport facilities is an important
component of the system of physical facilities.  Airports in the
region are served by infrastructure supporting various ground based
modes.  The regional highway network is the most extensive access
system, reaching all of the general aviation airports in addition
to the air carrier airports.  Regional highways are illustrated in
Exhibit 4.7. Public transit access is less readily available to air
travellers as shown in Exhibit 4.8 which outlines rail transit
routes in the region.  Metropolitan Oakland International Airport
has a.bus link to the Bay Area Rapid Transit (BART) rail system.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


4.3.1  Commercial Service Airports

San Francisco International Airport

     From what began in 1926 as a modest 160-acre site located well
outside the city, San Francisco International Airport has grown to
claim a total site of some 5,270 acres.  The site, located on the
west shore of San Francisco Bay, consists of both upland and
submerged saltwater bayland.  The airfield system occupies
approximately 1,700 acres, land partially consisting of reclaimed
tidelands.  Undeveloped areas are several and include: the Bayshore
Parcel, 180 acres sited near the freeway; the San Bruno Interchange
Parcel, 18 acres west of the United Airlines maintenance hangar;
the North Field Parcel, a 150-acre parcel on the north field, north
of Flying Tigers and JAL airfreight operations; and the East Field
Parcel, a crash-fire-rescue practice area accessible by taxiway C.

     San Francisco International Airport has two sets of
intersecting parallel runways: 28R-10L, 11,870 feet; 28L-10R,
10,600 feet; IR-19L, 8,901 feet (with a 600-foot displaced
threshold); and IL-19R, 7,001 feet.  Each is 200 feet wide.  They
are surfaced with asphalt concrete.  Three of the four runways are
equipped with Instrument Landing Systems (ELS).  An air traffic
control tower is situated in the center of the main terminal
building.

     San Francisco International is the dominant airport in the
region, serving over 70 percent of the total regional passengers in
1990.  Not surprisingly, it has by far the largest passenger
terminal complex in the region.  There are 2.6 million square feet
of space serving 80 gates in the passenger terminal, which is
configured as six piers.  There are also nine remote aircraft
hardstands (apron areas away from the terminal where aircraft can
park).  The north terminal contains two boarding piers, and the
south terminal has four, including the international terminal.  The
buildings surround a central public parking facility which has
6,800 stalls.

     Air freight facilities utilize about 90 acres at San Francisco
International, and provide for 34 aircraft parking  spots.  General
Aviation fixed base operators (FBO's) can accommodate 40 based
aircraft, and there are six private GA parking  places.  The
passenger terminal can accommodate some 80 commercial jet aircraft
at second-level passenger loading bridges.  Numerous support
facilities also occupy space at San Francisco International
Airport.

Metropolitan Oakland International

     With its simple beginning as a dirt strip in 1921 the
Metropolitan Oakland International Airport has evolved into a four-
runway commercial service airport occupying some 2,600 acres of
upland and wetland adjoining the east side of San Francisco Bay. 
The airport has experienced rapid growth in the past few years, and
in 1990 served 13 percent of the region's passengers.  Oakland
airport is laid out almost as two separate airports, with
commercial service occurring at South Field and general aviation
activities occupying North Field.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


     South Field consists of a single transport category runway,
Runway 11-29, 10,000 feet in length and 150 feet in width plus its
parallel taxiway.  North Field has three runways: 9R-27L, which is
6,212 feet long and 150 feet wide; 9L-27R, which is 5,452 feet long
and 150 feet wide; and 15-33, a short crosswind runway which is
3,366 feet long and 75 feet wide.  There is one designated
helicopter takeoff/landing area.

     Oakland's passenger terminal complex has two unit terminals
containing 20 second-level aircraft gates as well as one ground
level loading gate.  Terminal One also includes one international
arrival gate and a recently expanded international arrivals
building large enough to accommodate a 747.  'The international
arrivals facilities can process 500 peak hour arriving passengers. 
Surface vehicle parking  at the passenger terminal can accommodate
some 6,300 vehicles.

     Having become the region's hub for overnight small-package
cargo, Oakland has a large area (some 64 acres) devoted to air
cargo activity, including the Federal Express Metroplex facility
and an apron area used for belly cargo, both located west of the
terminal building.  Another 55 acres of air cargo development is
anticipated by the year 2002.

     Oakland's North Field is one of the region's largest and
busiest general aviation facilities, with a capacity of 640 based
aircraft, and occupying 980 acres.

     Oakland has two air traffic control towers.  One, serving
South Field, is located within passenger terminal 1. The second,
which serves North Field, is located adjoining the cross airport
dike.

 San Jose International

     San Jose International Airport occupies some 1,050 acres
adjoining the Bayshore Freeway on the north and the city of Santa
Clara on the west.  There are three parallel runways, one used for
air carrier aircraft, one used for commuter and general aviation
aircraft, and one used primarily by general aviation.  The general
aviation runway, 11-29, is 4,600 feet long and 100 feet wide.  The
air carrier center runway is designated 12R-30L, and is 10,200 feet
long and 150 feet wide.  The commuter/general aviation runway,
designated 12L-30R, is 4,419 feet long and 150 feet wide.

     With the recent completion of the new Terminal A, San Jose now
has two unit terminals (A and C) with a total of 31 gates.  Of
these, all 15 at Terminal A are second-level loading bridges, while
all 16 at Terminal C are ground-level gates.  A combination of
surface and structured parking provides some 8,250 total parking
spaces at the passenger terminal.

San Jose is also a busy general aviation airport, with 625 existing 
based  aircraft.  The  general aviation facility also includes the
San Jose jet center, the San  Jose  State  University  aviation
programs, and several other FBO and support activities.

     San Jose currently has a limited amount of space available for
air cargo.  Approximately 7 acres of dedicated air cargo apron is
located at the northeast corner of the airport.  This area, which
has no building space, is used for all-cargo and express mail
activity.  Belly cargo associated with airline operations is
handled at the air freight building south of Terminal C.

     Buchanan Field (Concord)

     Ground was broken in 1942 for an airport to serve Contra Costa
County.  Before construction could be completed, though, the
federal government stepped in and built two runways to serve the
war effort.  Today, Buchanan Field has two pairs of parallel
runways on a 530-acre site located near Concord, California.

     Runway 19R-IL is the primary runway, 4,400 feet in length and
150 feet in width.  The other major runway, 14L-32R is 3,951 feet
long and 150 feet wide.  Each has a 600-foot minimum safety area. 
Runway 1R-19L is 2,768 feet in length and 75 feet in width, and
Runway 14R-32L is 2,800 feet long and 75 feet wide.  The runway
surfaces are asphalt concrete.

     The primary runway and that lying parallel to it are equipped
with medium intensity runway lights (AURL), and 19R-IL has runway
end identifier lights (REIL) as well.  The other runways are not
lighted.  Non-precision landings are guided onto runway 19R-IL by a
visual approach slope indicator (VASI).  A terminal building
provides processing facilities for the based airlines, and there is
an air traffic control tower.

     In addition, there are three designated helicopter
takeoff/landing areas at Buchanan Field identified on the taxiways. 
Two are located on the east side of the airport, and one is placed
on the west side.

Sonoma County

     Sonoma County Airport has served Santa Rosa, California, and
nearby communities since 1939, with interim service for the U.S.
army during World War II.  It currently occupies 940 acres.

     Two crossed asphalt concrete runways support general aviation
and air carrier activity.  Runway 14-32 is the primary runway,
5,115 feet long, 150 feet wide, and ILS equipped.  Runway 1-19,
5,002 feet long and 150 feet wide, has no lighting system but is
non-precision landing equipped with a Very High Frequency Omni
Range Station (VOR).  There are four designated helipads and a
dedicated helipad lighting point.

     The airport has an air traffic control tower, and a small
terminal for commuter and air carrier traffic.

4.3.2  General Aviation Airports

     The airport s in the general aviation group by definition do
not host scheduled air carrier or commuter service, and also do not
have air cargo activity.  Most of the facilities accommodate
private or corporate aircraft and limited air taxi service.

     The general aviation airports are generally much smaller than
the commercial use airports.  A few GA airports, such as Hayward
(543 acres), Napa County (735 acres), Livermore (5 10), and Santa
Rosa Air Center, which is now closed (500), compare in acreage with
Buchanan Field (578 acres), but most are between 50 and 250 acres. 
General aviation runway lengths generally range between 2,000 and
3,500 feet, which is typical for the size and design aircraft
attracted to utilize these airstrips.  Three airfields have
significantly longer runways: Half Moon Bay (5,000 feet), Hayward
(5,024), and Napa County (5,931).  These airports could accommodate
smaller commercial passenger jets such as the Boeing 727 and 737,
and MD-80 series aircraft.  Santa Rosa Air Center (now closed) has
a 7,000-foot runway, a length which could possibly accommodate
larger air carrier aircraft such as the Boeing 757.  Precision
instrument approaches are possible at very few general aviation
airports, and the majority have no air traffic control tower. 
Exhibit 4.17 lists the airports in each category.

4.3.3 Military Airports

     Four military installations maintain airfield facilities in
the region.  These are the Naval Air Station at Alameda, located
near Oakland in Alameda County; Hamilton Field in Marin County;
Moffett Naval Air Station in Santa Clara County; and Travis Air
Force Base, southwest of Sacramento in Solano County.

Naval Air Station Alameda

     The NAS at Alameda contains 2,479 acres of property owned by
the U.S. Navy: 1,521 acres upland, and 958 acres of submerged
tideland in San Francisco Bay.  In addition, 155 acres are leased
from the City of Alameda.

     Naval Air Station Alameda provides support services to Naval
aviation facilities.  Berthing space at two piers accommodates
aircraft carriers, and ship maintenance is also accomplished at
Alameda.  The Naval Air Rework Facility Alameda allows for repair
and revamping of Navy jet and turboprop aircraft.

     The airfield has two crossed US-equipped runways: one 8,000
feet in length, 200 feet in width; the other 7,200 feet long, 200
feet wide.  Two helicopter landing areas are provided.  The
airfield' at Alameda NAS includes 469,700 square yards of aircraft
parking  apron and seven aircraft maintenance hangars.  There is an
air traffic control tower on site.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


Hamilton Field

     Hamilton Field, formerly Hamilton Air Force Base, is owned and
operated by the United States Army.  It has been surplused by the
military, and will be officially vacated in 1995.  The airfield is
no longer actively used by the Army.

     A single 8,000-foot runway is located on the site, and
numerous large aircraft hangars are present on the site.  The
housing and support buildings at the base once used by the Army
still exist, but are largely vacant.  There is no air traffic
control tower.

      Local ballot measures regarding the future of the airfield
have shown that the majority of voters did not support future civil
use.

Moffett Field

     Moffett Field (formerly called Naval Air Station Moffett
Field) was an airfield used primarily by Navy antisubmarine
aircraft to patrol Pacific Coast waters.  In 1992 the portions of
the airfield and landside support facilities used by the Navy were
excessed by the military, and will be vacated by 1994.  The entire
airfield facility has been given over to the National Aeronautics
and Space Administration (NASA), which will operate the facility in
the future.  Other future users will include the Ames Research
Laboratory, which has supported NASA on the site for many years,
and a number of other government and private companies who have
related government contracts and derive direct benefit by being
located on or adjoining the airfield.

     The 2,263-acre site has two parallel runways separated by 625
feet and fully instrumented.  One is 9,200 feet long and 200 feet
wide; the other is 8,124 feet long (7,517 feet with displaced
threshold) and 200 feet wide.  There are four aircraft maintenance
hangars and 472,300 square yards of aircraft parking apron.

There is an air traffic control tower in continuous operation at
Moffett Field.

Travis Air Force Base

     Travis Air Force Base is an active military airfield.  For
example, the base was heavily used to transport military personnel
back from the Persian Gulf conflict.  The base has two parallel
11,000-foot runways and significant passenger processing
facilities.  Travis' military mission is expected to continue, and
may be expanded.

Chapter 2: Introduction                            September 9, 1994


4.3.4  Special-Use Airports

     The facilities in this category provide services for aircraft
which are unique.  The Commodore Center Seaplane Base is located in
southern Marin County.  It has a 10,000-foot takeoff/landing area
length.  San Francisco's public-use heliport, which is not active
at this time, is located on a pier at the waterfront near
Fisherman's Wharf.

4.3.5  Private-Use General Aviation Airports

     Most of the private general aviation airports in the region
are airfields made up of a short, unpaved runway without
navigational aids, and minimal aircraft storage and other support
facilities. Public use and private use facilities in the airport
system are shown together in Exhibit 4.6.

4.4    BASED AIRCRAFT

     This section presents based aircraft and fleet mix data for
the four groups of airports in the system.  A complete set of
numbers is provided in the data summary table, Exhibit 4.17. The
distribution of the total based aircraft by county is then
illustrated in Exhibit 4.9.

4.4.1  Commercial Service Airports

     Most of the air carrier airports in the region are home to a
significant number of general aviation aircraft.  Concord, with
635, and San Jose, with 525, have the greatest number of based
aircraft.  Sonoma County Airport has 454 based aircraft.  Oakland,
which has lost significant numbers of based general aviation
aircraft in the past 10 years, now has 366 based aircraft, all of
which are located at North Field.  San Francisco, the exception to
the above statement, has very few based general aviation aircraft
(29), as most of the airport is devoted to passenger and air cargo
activities.  Of the five commercial service airports in the region,
San Jose is perhaps the dominant corporate/business airport, having
the greatest number of twin-engine piston-powered aircraft,
business jets, and rotorcraft.

4.4.2  General Aviation Airports

     The number of based aircraft at the general aviation airports
varies widely by facility.  Several airports have over 600 based
aircraft, most of which are single-engine piston airplanes.  Only
Hayward and Livermore have more than one based jet aircraft.  Gnoss
Field has one; the balance have none at all.  The small number of
rotorcraft in the system are based at a few GA airport locations
across the region, including Hayward, Gnoss, Napa County, Half Moon
Bay, and Livermore.  At Sky Soaring, a prominent gliderport, 20 of
the 23 based aircraft are gliders.  Few of the public-use GA
airports have based gliders, except Byron, which has 24 gliders in
the mix of based aircraft.

Chapter 2: Introduction                            September 9, 1994


     Hayward Air Terminal has the largest number of twin-engine
aircraft, while Oakland has the most jets and rotorcraft.  Of the
30 based jet aircraft in the system Oakland has over 68 percent
(34), while Hayward has some 18 percent of the total system's
multi-engine GA aircraft (114 of 636).  This reflects these two
airports importance to corporate and business aviation users.  The
chart below, Exhibit 4.1, displays the distribution of general
aviation based aircraft by county, and clearly shows the dominance
of Alameda and Santa Clara counties.

4.4.3  Military Airports

     The aircraft based at the military facilities are quite varied
in  and capability.  The number may change at any time due to the
state of the national defense.  NAS Moffett Field, for example,
functions primarily as a base and practice field for pilots of the
P-3, the Lockheed Orion antisubmarine aircraft.  Thus of the over
121 based aircraft, about 74 are the P-3.  Sixteen of these based
aircraft are helicopters.  NAS Alameda is home to some 56 U.S. Navy
aircraft, including approximately 16 Douglas A-4 Skyhawks, attack
aircraft carried shipboard, 13 of the Vought A-7 Corsair II, also
an attack jet, and 10 Douglas KA-3B Skywarriors, which are
refueling aircraft.  The total includes 12 based helicopters. 
Hamilton Field currently has no based aircraft.  Though it is used
by the U.S. Coast Guard, they do not base any vehicles there.

4.4.4  Special-Use Airports

The Seaplane Base in Marine County, Commodore Center, has three
based aircraft.


4.5    AIRPORT ACTIVITY

     Information about airport  activity was collected for the year
1990 to document current levels and to provide a basis for
forecasting.  Airport activity information listed here includes
enplaned passengers, annual aircraft operations, peak hour
operations, and annual air cargo volume.  The data is detailed in
Exhibit 4.17.

4.5.1  Commercial Service Airports

     The five commercial service airport s enplaned 21.4 million
passengers in 1990.  San Francisco International Airport enplaned
15.2 million passengers, which is 70.8 percent of the region's
total.  San Jose enplaned 3.4 million passengers (15.8 percent of
the region's total) and Oakland enplaned 2.7 million passengers
(12.8 percent).  Buchanan Field and Sonoma County enplaned 50,000
and 65,765 passengers, respectively, accounting for the remaining
0.6 percent of the region's total annual passengers.  The
distribution of passenger enplanements is illustrated in Exhibit 4.
10.

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


     In 1990 San Francisco had over 430,000 operations.  Most of
these were either commercial passenger flights or air cargo
operations.  Although this still made SFO the busiest airport in
the region, its share of the region's total operations was only 65
percent, compared to its nearly 72 percent of the region's total
passengers.  Two factors may account for this: (1) many of SFO's
international and other longer distance flights use larger
passenger capacity aircraft; (2) SPO flights tend to have higher
load factors.  In other words, SFO serves more passengers on more
flights with larger aircraft at higher load factors.

     San Jose saw a total of 95,778 air carrier operations in 1990
(19.5 percent of the region's total), while Oakland South Field had
74,000 (15.1 percent of the total for the region).  Concord, with
1,285 operations, accounted for 0.3 percent of the total, and
Sonoma County, with 439 operations, had 0.1 percent of the region's
total.  Exhibit 4.11 shows the distribution of air carrier
operations by airport.

     The following chart, Exhibit 4.12, displays the breakdown of
total 1990 operations by  of service for the five commercial
airports.  San Francisco has the highest volume of operations
overall, and serves the greatest number of commuter and air taxi
flights as well.  Most of the operations at Buchanan Field and
Sonoma County are clearly devoted to general aviation, with some
regional traffic and proportionally few air carrier movements per
facility.

     Air cargo activity for the year 1990 is concentrated at San
Francisco and Oakland, with nearly 94 percent of the region's total
air cargo processed at these two airports.  The primary difference
between the two is that most of San Francisco's cargo is belly and
traditional air cargo, while Oakland has focused on overnight
small-package cargo operations, as witnessed by the large presence
of Federal Express.  Between 1990 and 1992 Oakland has seen a new
trend in air cargo: the emergence of 2nd and 3rd day air service,
as well as direct distribution of manufactured goods.  As a result,
total cargo volumes at Oakland have grown by some 62 percent in the
last two years.  San Jose processes less air cargo (some 60,000
tons, or about 6 percent of the region's total).  Concord and
Sonoma County have very little air cargo activity, levels mostly
attributable to local demand for overnight package services such as
Federal Express and UPS.  The distribution of air cargo volume by
airport is illustrated in Exhibit 4.13, for the year 1990.

     A few of the facilities have significant levels of operations. 
Hayward, Livermore, and Reid-Hillview had over 200,000 operations
each in 1990.  Gnoss, Napa County, Nut Tree, San Carlos, and South
County have over 100,000 annual movements.  Others, such as Byron,
Cloverdale, Parrett Field, Rio Vista, and Sonoma Sky Park, have
fewer than 20,000 annual operations.  These airports also have
small numbers of based aircraft.  Exhibit 4.14 shows the
distribution of general aviation operations by county.  Comparison
with Exhibit 4.9, illustrating the based aircraft distribution by
county, is somewhat revealing.  Santa Clara County has the greatest
percentage of based aircraft, but does not match the number of
general aviation operations in Alameda County.

4.6    CAPABILITIES/CAPACITY

     This section of the airport system plan presents generalized
information about current airport facility capacity as determined
by reviewing existing facilities, activity levels, and capacity
data from current airport master plans.  Comparison of existing
facility capacity and existing levels of demand then made it
possible to assess the individual airports' ability to accommodate
future growth in activity.  The capability analysis includes Arced
Facility capacity and Landside Facility capacity.  Arced facility
capacity measures include peak hour runway capacity and annual
runway capacity (expressed as annual service volume).  Landside
facility capacity measures include based aircraft capacity,
passenger terminal capacity, and air cargo capacity.  While
generally accepted methodologies exist for determining runway
capacity, similar methods for determining overall passenger
terminal or air cargo facility capacity are not readily available. 
This an analysis therefore relies heavily on data obtained from the
individual air carrier airports.

4.6.1  Arced Facilities

     Airport arced capacity may be limited by a number of factors,
including runway capacity, taxiway capacity, or gate capacity.  The
FAA has established standards for in and lateral separations of
aircraft, which take into account air traffic control capabilities,
fleet mix, and airfield configuration, and these affect the arced
operational capacity.  Operational constraints on the airfield also
include the length of the runways and the structural integrity of
their pavement system.  Larger aircraft need relatively lengthy
runways, and repeated utilization by heavier aircraft will demand
substantial runway strength.

     The annual service volume for each airport is a measure of
capacity generally dependent on the number of runways.  The figure
varies by airport, however, based on the runway configuration,
spacing between runways,  of lighting and instrumentation, and
other factors.  The capacities at the commercial service airports
in the region thus differ widely.  Oakland and San Francisco have
the highest annual capacities, each at or just in excess of 500,000
operations per year.  The air carrier runway at Oakland has an ASV
of 240,000 annual operations.  San Jose can accommodate 355,000
operations annually, and Concord and Sonoma County have service
volumes of approximately 300,000 operations each.  The number of
commercial flights in a year is restricted by a number of
variables, including the length and strength of the runways and
fleet mix considerations.  The annual air carrier operations
capacity (expressed as annual service volume) is identified for the
major commercial service airports.  Both Concord and Sonoma County
have significant limitations placed upon commercial air carrier
service in consideration of the neighboring community, evidenced by
their annual air carrier operational capacity relative to the
annual service volume.  Total peak hour capacity is noted as
another constraint on the airport. throughput.  Both the capacities
in VFR and IFR conditions have been mentioned because dramatic
reductions occur when an airport is operating under instrument
flight landing procedures during severe weather conditions.  San
Francisco exemplifies this significant change as it moves from 105
aircraft per hour VFR to 53 aircraft IFR.  Similarly, San Jose has
its

4-13




MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


airspace capacity restricted to a single instrument approach during
IFR conditions.

     As a region the general aviation airports are currently
utilizing about two-thirds of the total annual arced capacity
(annual service volume).  This condition varies, however, from
airport to airport.  Some small facilities with low levels of
activity are operating at less than 10 percent of their annual
runway capacity.  These airports are Cloverdale and Rio Vista. 
These airports also combine for only six based aircraft.  Other,
larger airports are using much more of their runway capacity,
including Livermore at 90 percent and San Carlos at 68 percent. 
The other general aviation airports range from 25 percent to 55
percent of their annual runway capacity.


4.6.2  Landside Facilities

     Landside activity limitations include the passenger terminal
size, number of auto parking  spaces, vehicular access, and
aircraft parking capacity.  To date insufficient research has been
done to establish standards for passenger terminal capacities. 
Current estimates from the three large commercial service airports
indicate their total annual passenger capacity to be about 31
million for San Francisco, 8.5 million for Oakland, and 10.9
million for San lose.  San lose has a terminal capacity shortfall. 
Terminal C is operating above design capacity, with functions
located at non-terminal building sites.  San Francisco
International has insufficient domestic and international terminal
capacity.  The passenger terminal at Oakland has immediate baggage
handling and security shortfalls, but with the recent addition of
five new gates has an adequate terminal capacity availability.

     Ease of vehicular access and auto parking are also important
capacity considerations.  Measures include on-site roadway level of
service and curbside congestion.  Roadway level of service is a
measure of traffic flow conditions designated by the letters A
through F, with A the highest level or best condition on the scale. 
San Jose enjoys an excellent level of service on its airport
roadways.  They are lacking in on-airport rental car parking,
however.  Oakland has considerable congestion at the passenger
loading/unloading areas.  Terminal access roadways at San Francisco
International are inadequate in the peak periods when congested
conditions develop around the terminal curbside, but seem to have
sufficient long-term and short-term public parking  space. 
Regional access is being improved by the work of Caltrans on U.S.
Highway 101.

     The based aircraft capacity at these facilities is 'ample, for
the most part.  Sonoma County and Concord have room for 850 and 800
based aircraft, respectively, with Oakland and San Jose at about
the same levels in the 600-700 aircraft range.  Oakland is at 62
percent of its based aircraft capacity and San Jose is feeling some
pressure, currently operating at over 87 percent of its based
aircraft capacity.  San Francisco shows a great departure from this
provision of space, with only 46 general aviation based aircraft
places available (the 30 existing based aircraft represent 65
percent of capacity).  All of these commercial facilities except
San Francisco

4-14




MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


     International Airport thus can currently support based general
aviation activity in addition to their current level of demand. 
The general aviation element of the airport system is currently at
just under 70 percent of the total based aircraft capacity.  Those
airports having the highest occupancy rates are Livermore (106
percent), Palo Alto (85 percent), Hayward (83 percent), and San
Carlos (76 percent).  At the other end of the spectrum are Rio
Vista, at 25 percent of capacity, Half Moon Bay at 26 percent, and
Napa County at 40 percent.

     Of more importance than total system capacity, however, is the
regional distribution of available capacity in relation to demand. 
Santa Clara County, for example, had a total of only 446 based
aircraft vacancies in 1990.  Alameda County's airports also face
congestion at Hayward and Livermore (combined 93 percent of
capacity), while Oakland North Field has some room to grow,
currently at 62 percent of based aircraft capacity.

   4.7     CONSTRAINTS

     Previous sections outlined existing airport facilities, levels
of airport activity, numbers of based aircraft, and the airports'
physical capability/capacity to accommodate current and future
demand.  There are additional factors beyond the airports' physical
capacity, however, which place limitations on how much activity
can/will take place at each airport.  These constraints are
airspace, environmental, physical, and policy.

     Airspace constraints relate to regional airspace issues.  The
nine-county region contains over 50 airports, which in 1990
generated over 4 million operations.  This translates to almost
11,000 operations in the region every day.  The region's five
commercial service airports enplaned over 21 million total
passengers in 1990, making it the sixth busiest region in the
nation.  With this level of aviation activity the regional airspace
is congested and complex.  From an air traffic standpoint all of
the region's airports are interrelated, and affect each other.  In
planning for the total airport system it is therefore necessary to
evaluate the airspace environment.

     Environmental constraints as discussed here are those related
to the natural environment, including such things as wildlife,
wetlands, and San Francisco Bay.  Two of the major commercial
airports, Oakland and San Francisco, are situated on the Bay, and
host a variety of wildlife.  Development at Oakland is also
affected by the presence of non-Bay wetland areas.  Wetlands exist
to a lesser degree at other airports as well.  Construction of new
runways would affect wetlands or require Bay fill.

     Physical constraints may be manifested in a variety of ways,
including such things as limited airport size or the presence of
physical barriers to growth such as highways, railroads, rivers, or
buildings.




4-15




MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994

     Policy constraints include noise, safety, and other community
compatibility issues.  Neighborhoods affected by overflight noise
will be reluctant to support growth which win promote substantial
increases in commercial aircraft activity, and the noise which may
come with that activity.  Terminal expansion, for example, may be
viewed by communities as a vehicle for encouraging more flights
with the additional passenger processing capability, and opposed as
strongly as runway capacity increases.         Other constraints on
airport utilization include restrictions placed upon air traffic
due to community concerns.

     These constraints have historically shaped the growth and
development of the entire regional airport system, and will
continue to do so in the future.  This section identifies
limitations on current operations and addresses factors potentially
constraining future airport development and growth.  These
constraints are discussed in some detail for the individual
commercial service airports and more generally for the military,
general aviation, and special-use airports.

4.7.1  Airspace Constraints

     Safety is the greatest concern in aviation and to maintain
safe conditions limitations have been imposed by the FAA in order
to manage the regional airspace.  New technological advancements,
when developed and implemented, may allow for more aircraft to be
safely processed within the terminal areas.

     There is a substantial amount of interaction among the
operations at the numerous airports in the region, requiring an
established user's hierarchy for normal (non-emergency) conditions. 
The air traffic pattern at San Francisco International is dominant
because the volume of air carrier traffic generated as a percentage
of the total is so much greater than that of the other airports,
and traffic associated with other facilities must conform.  The
operations at military facilities in the region can cause flight
delays into and out of nearby commercial airports as the FAA
recognizes the importance of United States defense requirements. 
Civil flights will have to yield to military operations.  The
proximity of Alameda NAS to Oakland will affect Oakland operations
though a minimal number of interruptions will occur in a year. 
There are several other conflicts due to their proximity.  In
instrument conditions, conflict between aircraft simultaneously
approaching Hayward and Oakland will result in a delay to those
using Hayward Air Terminal.  Flight in the region is regulated by
various controls and restrictions identified by the FAA.  These may
hinder flight in the region.

Controlled airspace is identified.in the following ways:

        -    Terminal Control Areas (TCA) [permission and
             communication required, speed restricted] (these areas
             are now referred to as "Class B Airspace")
        -    Terminal Radar Service Areas (TRSA) [no permission
             required, communication required, speed restricted]
        -    Airport Radar Service Areas (ARSA) [permission
             required, speed restricted]

        (these areas are now referred to as "Class C Airspace")

MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


4.7.2  Environmental, Physical, and Political Constraints

     Future growth will be limited by development constraints on
site, quantified here.  Other constraints on facility expansion
will be noted for the major commercial airports and the others for
whom the issue is quite significant.

San Francisco

     The San Francisco International Airport plays an important
role in the community, and in working toward being a good neighbor
has had to restrict its activities in several ways.  Regulation has
long been instituted at San Francisco International to control the
noise affecting the community.  Most recent noise abatement
regulation was instituted in 1988 by the Airports Commission, and
restricts airport noise by requiring conversion by operators to
quieter Stage 3 aircraft and limiting nighttime use by aircraft
other than Stage 3

     Additionally, SFO is constrained by the absence of sufficient
land area for a new runway and passenger terminal development.  The
airport is landlocked by the Bayshore Freeway (Highway 101) to the
west, and San Francisco Bay to the north, east, and south.  Any
major new runway development would likely involve Bay fill.  The
president of the San Francisco Airport Commission has stated in a
letter to BCDC dated June 15, 1993 that the airport (SFO) has no
foreseeable need or plans for additional runways that would require
fill in San Francisco Bay.  There are a number of undeveloped areas
on site, identified already in the facilities section of this
chapter, which could be used for support facilities.  Future
development at the airport is limited to these parcels or to
redevelopment of existing facilities.

Oakland

     Metropolitan Oakland International Airport has no curfew and
no limit on the number of daily or annual operations.  It does
enforce noise abatement procedures to reduce noise impacts on the
residential communities around the airport.

     Although Oakland airport has considerable land area which
could accommodate development of passenger, air cargo, general
aviation, or other facilities, the airport has significant areas of
environmentally sensitive property.  These areas have created
development constraints at Oakland in the past.  These include
habitat for endangered species at the west end of runway 11-29;
scattered wetland areas throughout the airport; several open water
areas; and scattered wildlife habitat related to these wetlands. 
Although these areas do not significantly constrain passenger
terminal development, they may limit the long-term development of
air cargo, aircraft maintenance, and other support facilities.

     In addition, Oakland is constrained by the presence of San
Francisco Bay to the southeast, southwest, and northwest of the
primary air carrier runway.  Extension of this runway would

4-19




MTC Regional Airport System Plan Update
Chapter 2: Introduction                            September 9, 1994


involve Bay fill.  Construction of an additional air carrier runway
at South Field would involve either Bay or wetland fill, or both. 
The Port's current 2002 Airport Development Plan does not foresee
the need for a new parallel air carrier runway at projected levels
of activity in this plan.  Rather, that plan primarily includes
landside development projects (such as passenger terminal
expansion, new parking , roadway improvements, and new air cargo
facilities) seeking to achieve a balance between landside and arced
capacity.  In the longer term, the regional airport system plan has
identified a need for additional runway capacity somewhere in the
region, either at one of the three existing air carrier airports or
at Travis AFB or a new North Bay site.

San Jose

     San Jose International Airport has established a number of
operational restrictions to address the noise and safety issues,
and to reduce the airport's impacts on adjoining communities.  In
addition to noise abatement Right tracks and arrival and departure
procedures, San Jose has established a curfew which limits the
hours of airport operation.  The airport is closed between the
hours of 11:30 p.m. and 6:30 a.m. This reduces the total amount of
daily activity at the airport, and also creates some congestion
during the morning hours.  If continued into the future, the curfew
will constrain activity at the airport and cause increased
congestion within the available operating time envelope.

     San Jose International Airport is located within an intensely
developed urban area and operates on an extremely limited site. 
The 1,050-acre site is not sufficient to accommodate all aviation
demands.  As a result, future development will involve difficult
choices between competing sectors, including passenger facilities,
air cargo development, and general aviation.

     Because of its location and limited size, San Jose is highly
constrained by existing development.  The runway system is limited
in length by the Bayshore Freeway (Highway 101) on the north and
Interstate 880 on the south.  To the west and east the airport is
limited by urban development and the Guadalupe River, respectively. 
The passenger terminal area is also highly constrained by the size
and shape of the land available between the runways and the airport
access road and the river.  In addition, the presence of high-rise
towers in the vicinity of the airport will constrain the airport 
in its planning for facility improvements and operational
expansion.

Concord


     Nestled in the northern part of Contra Costa County, Buchanan
Field has, by County policy, placed limitations on both its general
aviation and commercial airline capacity.  The total number of
based aircraft is limited to a maximum of 850 spaces, a level
forecasted in the Master Plan for the year 2005.  Along with this
restriction on growth of general aviation activity, air carrier and
commuter airline service are limited.  Air carrier service is
capped by policy at 7 flights daily, and the commuter service is
held at a similar level, leaving the enplaned passenger

potential at less than 180,000 in the year 2010, according to their
Master Plan.  Pavement strength and runway length will create their
own restrictions on air carrier possibilities, they have noted. 
Physical restraints prevent runway extension.

Sonoma County

     The County of Sonoma has placed restrictions on its airport
operations and facilities development in order to meet its goal of
safe and compatible air service.  Commercial air carrier flights at
Sonoma County Airport, involving commuter and scheduled airline
service, are restricted in number and in combination by the County. 
In addition, the County has set policies which set limits to
physical improvements at the airport.  The current runway (5,000
feet) cannot be lengthened, and current runway strength (95,000-
pound limit on gross takeoff and landing weight) cannot be
increased.  Because of this weight limit, large air carrier
passenger jets (such as 737 and MD 80 series, which have maximum
takeoff weights of 135,000 to 150,000 lbs) cannot use the airport
for scheduled service.

McAteer-Petris Act and BCDC Constraints

     The McAteer-Petris Act (Title 7.2 of the California Government
Code) and Bay Conservation and Development Commission (BCDC) policy
allows for some Bay fill for airport capacity enhancement projects,
but such fill must be the minimum amount necessary, and the fill
would only be allowed if there are no feasible upland alternative
for these projects.

4.8    AIRPORT PLANS

4.8.1  Airport Master Plans

     The master plans of each airport have been reviewed to
identify future improvements and anticipated facility expansion by
airport.  Examination of their capital improvement programs (CIPS)
will provide clues to the funding levels and areas in which they
are focused.  Plans and policies of agencies at varying levels of
government who may effect future change are also identified.

     Detailed information about the regional air carrier airports'
master plans is provided, with a summary of general aviation
airport plans.

San Francisco

     San Francisco International Airport plans to accommodate
future growth by expanding and improving passenger and cargo
processing facilities and maintenance facilities.  Less emphasis
has been placed on airfield modifications.  Their Master Plan,
completed in November of 1989, identifies various improvements for
initiation in the near term, Fiscal Years 1988-1996, and the

Buchanan Field

     The Buchanan Field master plan is a balanced response to
anticipated general aviation and air carrier/commuter demand.  They
have focused their efforts on best utilizing available land on site,
respectful of the existing airport configuration.  No runway
extension has been suggested, but there will be work done on the
taxiway system.  This master plan was completed in 1988.

Airfield
   -    Redesign taxiway system leading to Runway 32L and nearby
        multi-taxiway intersection.  New Taxiway M parallel to Runway
        1L-19R.

General Aviation
   -    Increase GA parking  from 629 spaces to 849 based aircraft
        parking  spaces.
        Increase transient aircraft parking  from 37 to 69 spaces.
        Add other hangar spaces and tie-downs.

Terminal
   -    Construction of an airline terminal on the west side of the
        airport to accommodate 180,000 annual enplaned passengers and
        a restaurant.  There would be 700 adjacent auto parking 
        spaces.

Other
   -    Crash-fire-rescue building. 
   -    A fuel farm.


4.8.2   Other Plans

     Sonoma County has closed Santa Rosa Air Center because it was
not compatible with its surroundings.    The county is home to a
fair number of the region's based aircraft.  Consideration is also
being given currently to the closing of Reid-Hillview in Santa Clara
County.

5       AVIATION DEMAND FORECASTS

     The following text describes the process used in producing the
updated forecasts for passengers, air cargo, and general aviation
for the 1993 Regional Airport System Plan Update.

5.1    PASSENGER ACTIVITY FORECASTS

     The generalized approach to preparing passenger forecasts was
to review previous forecasts; document air travel trends both within
and outside the region; establish a forecasting methodology; and,
using that methodology, produce forecasts.  These steps are
described below.

5.1.1  Review of Previous Forecasts

     In preparing these forecasts the previous aviation forecasts
listed below were reviewed to determine how well they predicted
future activity levels, and whether and how their methodologies
might be applied to the current forecasting effort.  Those forecasts
included a variety of local, regional, state, and national efforts
developed over the past 10 years.

    1.  MTC Regional Airport System Plan Forecasts (1980 and 1985)
    2.  Current individual airport master plans
    3.  FAA San Francisco Hub Forecast (1986)
    4.  FAA National Aviation Forecast (1991)
    5.  FAA National Terminal Area Forecast (1990)
    6.  California Aviation System Plan (CASP) Forecast (1989)


     Exhibit 5.1 ("MTC Regional Airport System Plan Update -
Forecast Comparison") displays these previous forecasts as well as
historic data (for years 1970 through 1990) for both the region and
the nation.  Included are the total annual passenger figures for
each airport, the regional total, and the average annual growth rate
for each five-year period.  Because the various forecasts were
prepared at different times, the forecast years did not always match
those required for the current MTC forecast (1995, 2000, and 2010). 
In those cases, previous forecasts were either interpolated or
extrapolated, or both.

     Accompanying Exhibit 5.1 are a series of supporting exhibits
which graphically display the data.  These include historical
comparisons of the 1980 MTC high and low passenger forecasts and
actual activity in the nation and region.  In addition, exhibits for
each of the five air carrier airports display historic trends from
1970 to 1990 (where available) and the range of forecasts for each
airport for the years 1995, 2000, and 2010.  Also included is a
historic 20-year chart showing total air carrier enplaned passengers
for the Bay Region and the U.S. from 1970 through 1990.  This chart
is instructive in displaying the historic volatility of the
industry, and the resulting difficulty in developing forecasts which
are accurate for any individual year of the forecast period. 
Nonetheless, the chart clearly shows the growth trend over the 20-
year period,

which averaged nearly 4.2 percent per year.  It also reveals
remarkable similarities between the region and the rest of the U.S..

    Exhibit 5.11 breaks down passenger activity at SFO, OAK, and SJC
into the major components of Domestic Origin & Destination (O&D)
traffic, Domestic Connecting traffic, and International traffic. 
These data breakdowns by type of traffic and by airport are
necessary in analyzing historic trends in the region and preparing
more accurate forecasts for the future.  Knowing simply the total
number of passengers in the region, for example, does not allow
analysis of the complex market share interactions among the region's
airports.  Nor do aggregated totals provide the level of detail
needed to build an understanding of the unique roles that the
individual airports play - either in the region or on the route
structures of the airlines they serve.

MTC Forecasts (1980 and 1985)

Previous MTC forecasts employed a linear regression analysis of Bay
Area air travel against U.S. Gross National Product (GNP) and
airline yield.  Airline yield was used as a surrogate variable for
the price of air travel.  These two factors were intended to reflect
the underlying economic and pricing forces that affect air travel
demand.  The 1980 plan included 'high' and 'low' forecasts based on
varying degrees of optimism regarding these forces. MTC's 1980
forecasts included a "High" forecast of 56 million annual passengers
and a forecast of 45 million annual passengers in the region in the
year 1997.  The high forecast was based on annual growth rates of
5.8 percent from 1977 through 1987, dropping to 2.7 percent from
1987 through 1997.  The low forecast used annual growth rates of 4.2
percent and 2.0 percent for the same two time periods.

    To see how well these previous forecasts predicted actual
activity, we looked at the high and low forecasts for 1990 and
compared them with the actual numbers for that year.  For 1990, the
MTC high and low forecasts were 46.6 million and 39.3 million total
regional passengers, respectively.  The actual regional total for
1990 was 42.8 million passengers, which is almost exactly in the
middle of the high and low forecasts.  In hindsight, the MTC
forecasts were very good in bracketing the future level of passenger
activity from 1985 through 1990.

     In 1985 MTC staff prepared an updated forecast for passenger
traffic, extending the period to the year 2005.  That forecast
showed a high of 58.7 million and a low of 48.7 million annual
passengers for 2005.  As shown in Exhibits 5.1 and 5.5, the 1985 MTC
forecasts we the lowest of all those included here.

Chapter 5: Aviation Demand Forecasts                September 9, 1994


Existing Airport Master Plans

     Existing airport master plans provided another source of
forecasts for the five individual airports.  There were two master
plan forecasts: (1) San Francisco (SFO) and Concord (CCR)
"unconstrained"; and (2) SFO and CCR "constrained." The
unconstrained forecasts illustrate the level of activity which can
be expected  if there are no major operational or policy constraints
on capacity at SFO and CCR.  The constrained forecasts illustrate a
lower level of growth at SFO and CCR due to operational and/or
policy limitations on capacity (airside, landside, and/or airspace)
at SFO, and due to policy limits at CCR.  These constraints are
described in more detail in the two airports' master plan documents. 
All forecasts for CCR are based on the current Buchanan Field Master
Plan, which was prepared when Concord had regular passenger service. 
As of 1993, however, Concord has no scheduled air service.  Both the
Concord Master Plan and this system plan assume that scheduled
passenger service will return to Concord in the future.

     San Francisco's current master plan was adopted in November
1992, and is currently being used to direct growth and development
of the airport.  Oakland's currently adopted airport master plan was
completed in 1978, and is currently being updated.  The Oakland
Master Plan Update process has been reoriented as a '10-year Airport
Development Program', which is expected to be completed in early
1994.  San Jose's current master plan was adopted in 1980.  The
current master plan update processes expected to be completed in
late 1995.  Concord's airport master plan summary report was
completed in 1988.  Sonoma County's updated airport master plan was
adopted in 1992.  In addition, Sonoma County Airport operation and
planning policy is contained within the Sonoma County General Plan. 
The Air Transportation Element, which provides policy on the
development and operation of the airport, was last revised in 1988.

     The constrained forecast for SFO reduces passenger activity
from the unconstrained forecast level of 55 million to 43 million in
the year 2010, and reduces passenger activity at CCR from 790,000 to
360,000 in the same year.  The net effect of these constrained
forecasts is to lower the region's total passenger volume for the
year 2010 from an unconstrained 89.4 million to a constrained 77
million.  Although SFO is planning for significant growth in
passenger traffic (much of it international), combining the
individual airport master plan forecasts reveals a future shift in
passenger market share away from SFO and toward OAK and SJC.  Under
the unconstrained forecast for 2010, SFO's regional market share
would fall from its 1990 level of 71 percent to 61 percent.  Under
the constrained foremast, SFO's share of the region's total
passengers would decrease to 56 percent by the year 2010.

1986 FAA San Francisco Hub Forecast

     In 1986 the FAA prepared a forecast for all five of the
region's air carrier airports, known collectively as the "San
Francisco Hub".  The FAA periodically prepares these forecasts for
the nation's large urban areas.  In other regions, such as Denver
(referred to below in the air cargo

MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


nation's large urban areas.  In other regions, such as Denver
(referred to below in the air cargo forecast), the "hub" forecast
includes only a single airport.  The San Francisco Hub forecast
included total air passengers and air cargo within the region, and
allocated passenger c forecasts to the five air carrier airports. 
Air cargo forecasts were kept at the regional level.  The forecast
used 1985 as the base year and included forecasts for the years
1990, 1995, and 2000.  The forecast used different average annual
growth rates for each five-year period.  At the regional level
annual growth rates were expected to be 4.9 percent from 1985 to
1990, 3.0 percent from 1990 to 1995, and 2.5 percent from 1995 to
2000.

     Concord, Sonoma County, and San Jose were predicted to see the
greatest annual growth rates, with Concord and San Jose seeing very
fast growth (21.5 percent and 10 percent per year. respectively)
between 1985 and 1990.  San Jose and Oakland, which together
accounted for only 20 percent of the region's passengers in 1980,
were expected to see 50 percent of the passenger growth from 1980 to
2000.  SFO, on the other hand, was expected to see the lowest annual
growth rates, with 3.5 percent from 1985 to 1990, 2.0 percent from
1990 to 1995, and 1.5 percent between 1995 and 2000.  The forecasts
showed a clear trend of shifting passenger traffic away from SFO and
toward the other airports in the region.

1991 FAA Aviation Forecast

     The FAA produces its nationwide aviation forecasts annually,
with the latest document (FAA-APO 93-1) published in February 1993.
This forecast establishes average annual growth rates for the
nation, and includes specific terminal area forecasts for the
nation's 32 largest hubs, including SFO.

     Although used here only for comparing passenger forecasts, the
FAA Aviation Forecast document includes a wide range of forecasts,
including passenger enplanements, operations, average aircraft load
factors, fuel consumption, number of passenger aircraft, number of
active general aviation aircraft, and number of active pilots.  The
FAA forecast is based on a number of leading economic indicators,
including the Gross National Product, the Consumer Price Index, and
an Oil and Gas Deflator.  In addition, the forecasts take into
account other factors such as the overall health of the airlines,
social and demographic trends, and world politics.

     The 1991 FAA aviation forecast indicates that average annual
passenger growth rates for the entire nation's airport system will
be 4.0 percent through the year 2002.  Between 2002 and 2010 the FAA
National forecast was extrapolated here using an annual growth rate
of 3 percent.  Using these annual growth rates produces a regional
forecast of some 84.4 million annual passengers by the year 2010,
approximately 5 million less than the sum of the individual airport
master plans (89.4 million).

     If the FAA's average annual growth rates are applied to each of
the region's airports equally, starting from their 1990 activity
levels, SFO would grow to nearly 60 million passengers by

2010.  This is higher than the airport's own forecast as contained
in the airport master plan.  San Jose would grow to over 13 million
passengers less than the airport's forecast) and Oakland would grow
to about 11 million in the year 2010 (slightly below the airport's
forecast).

     For the forecast period 1989-2005 the FAA aviation forecast
shows SFO passenger traffic growing at an annual rate of 2.1
percent, while the number of annual operations is expected to grow
at a slower annual rate of 1.1 percent.  Of the 32 hub airports
included in the FAA Aviation Forecast, only Los Angeles
International and Washington National are expected to have lower
rates of passenger growth than San Francisco International.  In
addition, only four other major U.S. airports are forecast to have
slower annual operations growth: Chicago-O'Hare, Atlanta-Hartsfield,
New York-JFK, and Miami.  Although the FAA national forecasts may 
useful in producing a forecast for the total region, applying the
same growth rate to each of the region's airports does not recognize
the individual growth dynamics of each airport.

1990 FAA Terminal Area Forecast

     The 1990 FAA Terminal Area Forecasts (TAF) include annual
forecast figures for each year from 1990 through 1995 and forecast
figures for the years 2000 and 2005.  These numbers were then
extrapolated to the year 2010 for comparison here.  The terminal
area forecasts, which represent a more detailed analysis of existing
conditions and growth potential at each airport than the national
aviation forecasts, apply different rates of growth for each
airport.  Between 1990 and the forecast year 2010 the TAF shows
total annual passenger growth as follows: San Francisco - 48
percent; Oakland -- 92 percent; San Jose - 138 percent; Concord -
408 percent; and Sonoma County -- 32 percent.

1989 California Aviation System Plan (CASP) by Caltrans

     The CASP forecasts project the highest growth of all those
reviewed.  In the year 2010 the CASP shows the five Bay Area air
carrier airports serving over 90 million annual passengers, a 114
percent increase over 1990 activity levels.  Similar to many other
forecasts, the CASP forecast predicts strong growth in the earlier
years, with annual growth rates falling off in succeeding years. 
The CASP forecast is similar to the combined forecasts of the
airport master plans in total regional passengers.  The CASP
forecast differs from the master plan forecasts, however, in that it
shows more growth at SFO and OAK and less growth at SJC.

5.1.2  Air Travel Trends

     A number of air travel trends may affect future air travel in
the San Francisco region.  These are briefly outlined below.





5-5



MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


International Travel Growth

    Many recent air travel forecasts suggest that international air
travel (and particularly travel to Pacific Rim nations) will be a
rapidly growing market for the next 10-20 years.  Although
international traffic accounts for only about 9 percent of all
regional passenger traffic, this segment will provide a strong
growth component, offsetting any weakness in the domestic market.

Domestic Travel Growth (O&D and Connecting)

     Underlying some of the air travel growth projections for the
Bay Area may be the effort of airline - "hubbing," which inflates
the actual Bay Area activity figures as connecting passengers change
planes at Bay Area airports.  San Francisco, Oakland, and San Jose
have each become hub airports to a certain extent (United at SFO,
Southwest at OAK, and American at SJC).  As of mid- 1991 connecting
passengers comprised some 11 percent of all passengers in the
region.  Federally collected origin and destination (O&D) data
suggests a low rate of growth in local Bay Area O&D air passenger
traffic.  Future growth in passenger traffic may be more the result
of increased hubbing by major airlines than to the growth in the
local O&D market.

Maturation of Markets

     In the 1970s and early 1980s a number of emerging air travel
markets saw rapid growth.  Since then, several of these markets to
and from the Bay Area have matured, and appear to be now
experiencing growth only in proportion to overall population and
economic growth.  Much of the growth in the region's O&D travel in
the past decade has been in long-distance markets (especially
international), which are now being served well by an increasing
number of carriers.

Airline Yield*

     Experts differ in opinion on whether airlines will be able to
hold future fares down in real terms.  The history of air fares has
been a steady downward trend.  However, the future may produce
higher fuel and labor costs, which cannot be offset by future
technology and productivity improvements. The impact of a constant
yield assumption in the MTC forecast, as opposed to a declining
yield assumption, would likely be to reduce Bay Area air travel
demand.  When combined with an assumption of no significant new
hubbing, these factors would produce low end forecasts.

*  The extent to which airlines' revenues exceed costs on each route

Demographics and Per Capita Air Travel

     Demographic hands are important in helping to forecast future
demand, particularly when factors such as discretionary income,
amount of leisure time, and attraction of first-time flyers are
included.  Air traffic growth has been boosted by all three of these
factors in the past, but this may change in the future.  Slower
population growth, a slowing in the growth in real disposable
income, and a decreasing number of first-time flyers suggest a
slower air travel growth rate in the future.

Telecommunications

Telecommunications, particularly video conferencing, may provide
substitutes for certain of business travel, particularly if economic
conditions worsen and the real cost of air travel increases and is
passed on to the passenger.  Since the Gulf War this form of
communication has attracted greater interest.

5.1.3  Forecast Approach

     In reviewing previous forecasting efforts, there is clearly a
wide variation in predictions about the future of air travel.  Among
those existing forecasts reviewed, the highest passenger forecast
was from the CASP, which predicted over 90 million annual passengers
by the year 2010.  The lowest forecast for that year was 71.5
million passengers, predicted in the FAA Terminal Area Forecast.  In
view of this uncertainty, it was considered necessary to prepare
more than a single forecast for passenger traffic.

     These forecasts therefore represent a range of views of the
future, from high to low.  This is consistent with the 1980 MTC
Regional Airport System Plan.  Using a range to show possible future
maximum and minimum levels of activity, this 1993 update of the
Regional Airport System Plan will be developed with the flexibility
to respond to this uncertainty about future levels of activity.

     After reviewing and evaluating the previous forecasting
efforts, and reviewing trends which may affect future growth,
approaches for producing high and low forecasts were developed.  For
the low forecast, a linear regression was developed based upon the
historic relationship between regional passengers and National GNP
and airline yield.  It was thought that a forecast based upon these
factors would represent a more pessimistic, 'bottom-line' oriented
view, and would reflect a growing caution within the airline
industry regarding the long-range outlook for growth.  This analysis
resulted in a year 2010 forecast of just under 71 million regional
passengers.  This is the lowest of all the forecasts reviewed, and
is considered to be the lowest foreseeable forecast of future
aviation activity.



5-7
   


MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


     The high forecast was developed using linear programming
methods by evaluating the historic relationships between regional
passengers and other factors:  U.S. passengers, regional population,
and regional employment.  Historic correlations between the
dependent and independent variables were generated to determine the
best fit.  That analysis showed an extremely high historic
correlation between regional passengers and total U.S. passenger
activity (R squared = .98). From 1970 through 1990 regional
passenger growth has been nearly identical to national growth. 
These two trends are shown in Exhibit 5.3.

     Using the linear regression model, the level of future regional
passengers is predicted to closely parallel national trends.  The
FAA national passenger forecast is based on an annual growth rate of
4 percent between 1990 and 2002.  From 2002 to 2010 the annual
growth rate was reduced to 2.6 percent.  This was consistent with
forecast growth rates for that time period contained in all the
other previous forecasts reviewed, with the exception of the CASP,
which shows a rate of 3.5 percent per year from 2000 to 2005.

     It should be noted that these MTC passenger forecasts are based
on historical relationships, which include past trends regarding
airline hubbing.  As such, they do not account for the possibility
of a major new hub operation at either Oakland or San Jose.  If
either were to become a major hub, total regional passenger volumes
could exceed the 84 million included in this forecast.  As of the
publication of this plan, however, American Airlines had
significantly downsized its San Jose hub, and the level of
connecting passengers at SJC had fallen.  In Oakland, Southwest
Airlines has now taken over all of Terminal 2, offering non-stop,
primarily O&D type service.  Many major airlines are now reducing
the number and size of their hubs, and rethinking the economics of
hub type operations as compared with the new Southwest Airlines type
of point to point service.  Considering recent events at San Jose
and the uncertainty of the nation's hub and spoke system as a whole,
it does not seem likely that the Bay Area Airport system will need
to plan for any major new airline hubs in the foreseeable future.

5.1.4  Selected MTC Regional Airport System Plan Forecasts

     Using the approach outlined above, the total regional passenger
forecast for the year 2010 includes a 'high' of 84,763,333 and a
'low' of 70,621,536.  The high forecast falls in the mid-range of
all the previous forecasts described above.  It is consistent with
the FAA national forecasts but is not as high as the CASP forecast. 
The 'high' forecast also falls between the unconstrained and
constrained forecast from the airport master plans. The 'low'
forecast falls just below the FAA terminal area forecast.  When
compared with the other forecasts reviewed above, this GNP trend
forecast is the lowest forecast of future passenger activity.  As
such, it is the minimum level of activity around which the region
should plan its system.

5.2     AIR CARGO FORECASTS

5.2.1   Review of Previous Forecasts

     Similar to the process used to prepare the passenger forecasts,
the air cargo forecasting effort began with a review of previous
forecasts.  Because of the small amount of air cargo handled at
Concord and Sonoma County, these airports were excluded from this
forecast.  Existing air cargo forecasts that were reviewed include
the following:

    1.  MTC Regional Airport System Plan (1980)
    2.  Current individual airport master plans
    3.  FAA San Francisco HUB Forecast (1986)
    4.  FAA National Aviation Forecasts (1991)
    5.  World Air Cargo Forecast, by Boeing Commercial Airplane Group
        (1990)
    6.  California Aviation System Plan (CASP) Forecast (1989)
    7.  California Air Cargo Study by Manalytics (1991)

   As with the passenger forecasts, the air cargo forecasts include
several exhibits.  Exhibit 5.12 displays the numbers associated with
the previous forecasting efforts as described below.  It also
contains several national and world cargo forecasts purely for
comparative purposes.  In addition, charts are included that present
the historic relationship between U.S. and regional cargo volumes,
and a comparison of the 1980 MTC cargo forecast versus actual cargo
activity.  Additional charts display the range of forecasts for each
of the fl= major air carrier airports.  Unless otherwise noted, all
references to "tons' in this forecast are to normal U.S. tons (2,000
lbs.).

1980 MTC Forecasts

     MTC's air cargo forecasts were based- upon a review of previous
forecasts completed by the FAA; the Air Transport Association (ATA);
aircraft manufacturers; and the air cargo marketing departments of
several major airlines.  These existing forecasts produced average
annual growth rates of between 6 percent and 18.5 percent for the
years 1977 through 1997.

     MTC's 1980 Regional Airport System Plan forecasts include both
'high' and 'low' forecasts, which, similar to the passenger
forecasts, created a range within which the future growth was
expected to fall.  Also similar to the passenger forecasts, actual
regional growth in air cargo between 1980 and 1990 fell between the
high and low 1980 MTC cargo forecasts.  For 1990, regional air cargo
totaled 950,000 tons, while the high forecast by MTC in 1980
predicted some 1 million tons and the low forecast predicted 914,500
tons.

Existing Airport Master Plans

    All three airports' existing master plans have detailed
forecasts of air cargo activity.  San Francisco's and Oakland's
forecasts have been extrapolated to 2010.  As a region, the combined
master plans show future growth of 8.5 percent from 1990 to 1995,
5.6 percent from 1995 to 2000, 5.9 percent from 2000 to 2005, and
6.6 percent from 2005 to 2010.  The total volume of air cargo in the
region is expected to be 3,453,221 tons by the year 2010 (see
exhibit 5.12). This is nearly the same as the CASP forecast
(described below).

1986 FAA San Francisco HUB Forecast

     This FAA foremast projects the region's total air cargo demand
through the year 2000 using annual growth rates of 4.5 percent for
1990-1995 and 4.2 percent for 1995-2000.  The forecast is based on a
continuation of then current (1986) market shares, with SFO
retaining 66 percent, OAK with 25 percent, and SJC with 9 percent. 
The FAA Hub forecast shows overall growth in air cargo volumes
growing from 950,307 tons in 1990 to about 1.5 million tons by the
year 2000, a total increase of just over 50 percent. 

1990 FAA National Forecast/1990 FAA Denver Hub Forecast

     One annual FAA Aviation forecast document does not contain a
forecast of future air cargo traffic.  This forecast was therefore
taken from the FAA's Denver Hub forecast, completed in 1990.  That
forecast shows air cargo growth from 1990 through 2010 at annual
rates of 4.9 percent for the first 5 years, 4.6 percent for the
second 5 years, and 4.1 percent for the last 10 years (2000-2010). 
The forecast shows total regional cargo volumes increasing to 2.3
million tons by the year 2010, a total increase of nearly 138
percent for the 20-year period.

1990 Boeing World Air Cargo Forecast

     In 1990 the Boeing Commercial Airplane Group produced a
worldwide forecast of air cargo.  The forecast generates annual
growth rates based on total revenue-ton-kilometers (RTKs).  This
figure includes a factor (distance in kilometers) which is not
included in the other forecasts.  The forecast is therefore
determined by both the weight of cargo as well as the distance it
travels.  In this sense, the Boeing forecast is not comparable to
the others.  Nevertheless, it is instructive to include it here as a
measure of overall worldwide cargo growth from 1989 to 2000. 
Factors affecting growth which were included in the Boeing forecasts
are: U.S. and world economic growth, world exports, world express
and small package market, labor costs, world oil prices and jet fuel
costs, and world air freight yield, among others.

     The Boeing forecast includes some historical data for
perspective.  From 1970 through 1988, according to the report, the
total world cargo volume grew at an average annual rate of almost 9
percent.  The most significant growth occurred between 1985 and
1988, when the average

5-11

MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


annual growth was 12 percent.  This growth may be partially
explained by the fact that Federal Express began reporting data in
1985.  This strong growth was shared by the San Francisco region,
which saw annual cargo growth rates of 14 percent, 19 percent, and
16.5 percent for these same years.

     The 1989 to 2000 forecast predicts annual growth of 7.3 percent
from 1989 to 1995 and 5.6 percent from 1995 to 2000.  It is called
the 'baseline' forecast.  The forecast also includes higher and
lower growth rate projections, reflecting alternative outlooks for
the world's economies.  These rates are:


        1989-1995      1995-2000

High    8.6%           6.4%
LOW     6.0%           4.9%
 
   Applying the baseline growth rates to the 1990 existing air cargo
volumes in the region produces a regional cargo forecast of 1.8
million tons in the year 2000.  This represents a total increase of
87 percent over 1990 volumes.

California Aviation System Plan (CASP) Update

     The state has produced two forecasts of air cargo, one (Phase I
report prepared in 1989) which includes SFO, OAK, and SJC, and the
other (Phase 2 prepared by Manalytics, Inc., in 1991) which includes
only SFO and OAK.  The first applied an average annual growth rate
of 3.7 percent to the region for the entire forecast period, 1990-
2010.  This forecast indicates the region's total air cargo demand
will approach 2 million tons in 2010, with SFO accounting for 66
percent, OAK at 24 percent, and SJC at 10 percent.  The Manalytics
forecast shows SFO growing by only 1.8 percent per year, while OAK
grows by 6.0 percent per year through the 20-year forecast period.

5.2.2  Air Cargo Trends

     There are a number of factors which may affect air cargo growth
and the distribution of that growth in the San Francisco region in
the coming 20 years.  These include worldwide, national, regional,
and local factors and trends.  Following are the major factors which
have been considered in the preparation of future air cargo
forecasts for the 1993 Regional Airport System Plan Update.  Much of
the world and national trends data was taken from the 1990 Boeing
World Air Cargo Forecast.


   1.   World air freight will grow more rapidly than mail, though
        both will see continued steady growth.


5-12




MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994

   2.   International markets will continue to outpace domestic
        market growth.
   3.   The U.S. airline share of world air  cargo  volume  will 
        decline  slightly  from  35  percent in 1989 to 33 percent in
        the year 2000.
   4.   The highest air freight  market  growth  will  occur  in  the 
        intra-Orient,  Europe-Orient,  and transpacific routes.
   5.   The  number  of  small  air  cargo  freighter  aircraft  will 
        grow  substantially,  primarily through conversion of
        existing passenger
   6.   Most 707s and DC8s will be retired from  the  medium-sized 
        airplane  fleet  and  be  replaced by 757-sized airplanes.
   7.   U.S. conversion to an all stage 3 fleet will force either an
        upgrading  of  stage  2  aircraft to stage 3 noise standards
        or force them out of the U.S. route system.
   8.   Air cargo  activity  will  remain  concentrated  at  very 
        busy  airports  near  major  population centers where there 
        is  ample  capacity  available  to  shippers  in  the 
        baggage  holds  of airliners.  [Source:  A Feasibility Study
        of regional Air-cargo Airports, a report to Congress; by FAA,
        August, 1991.]
   9.   It is appropriate that cargo  operations  be  collocated 
        with  passenger  operations  at  the busiest metropolitan
        area airports.... All cargo aircraft operations add little to 
        air  traffic congestion  and  delay  at  busy  air-carrier 
        airports....  Cargo  operations  require  the   same
        expensive airport  facilities long  runways,  highway 
        access,  and  support  infrastructure) as passenger
        operations.[Source: A Feasibility Study of Regional Air-Cargo
        report to Congress; by FAA, August, 1991.
   10.  Joint-use  agreements  at  military  airfields  or 
        conversion  of  surplus, former  military airfields may offer
        some of the best, least-cost alternatives for multi-use
        reliever  airports.[Source: A feasibility Study of Regional
        Air-Cargo a report to Congress; by FAA August, 1991.]
   11.  Because of its focus on passenger activity,  San  Francisco 
        International  will  achieve  air cargo growth  primarily  by 
        providing  more  belly  cargo  capacity  in  passenger 
        aircraft. Much of this growth will be related to expansion of
        the transpacific market.
   12.  Oakland will continue to see  strong  growth  in  all-cargo 
        activity,  particularly  the  small package and overnight
        express component of the air cargo industry.
   13.  Due to limited airport size, San Jose, like San Francisco,
        will  rely  on  increased  bellyhold capacity on passenger
        aircraft to provide most of its future air cargo growth.

5.2.3  Air Cargo Forecasts

     The 1980 MTC forecasts included high and low forecasts for both
passengers and air cargo.  Exhibit 5.14 shows how volatile the
regional and national air cargo industry has been in the past 10
years.  Between 1980 and 1990 the cargo industry saw a wide variety
of conditions, including decline, stagnation, and strong growth.  In
spite of this volatility, the MTC forecast found accuracy in 1990,
with actual activity falling within the predicted forecast range.

     Because of the uncertainty in accurately predicting future air
cargo trends, this MTC forecast also includes 'high' and 'low'
figures, which are displayed in Exhibit 5.15 below.  The high
forecast is based on annual growth rates of 5 percent from 1990 to
2000 and 4 percent from 2000 to 2010.  The low forecast is based on
annual growth rates of 4 percent between 1990 and 2000 and 3 percent
between 2000 and 2010.  The high forecast more closely resembles the
Boeing and FAA National forecasts, while the low forecast is more in
line with the individual airport master plans and the Phase I CASP
forecast.  The selected MTC/RAPC forecasts show a continuation of
the airports' current market shares.  The MTC Air Cargo Forecasts
shown in Exhibit 5.15 below display forecasts for each of the three
air carrier airports.  The basic forecast totals some 2,290,000
total tons for the region in the year 2010.  In addition, the
forecast displays a revised high forecast for Oakland airport.  This
revised Oakland cargo forecast is the result of significant changes
in air cargo trends in the past two years, and reflects the Port of
Oakland's revised air cargo forecasts published in May of 1993.  The
baseline air cargo forecasts for the RASP (shown in Exhibit 5.15)
were prepared in 1991 using historical data through 1990.

     Since these baseline cargo forecasts were prepared (1991)
Oakland airport has experienced a strong growth surge in two
specialized sectors of air cargo: (1) direct distribution; and (2)
second and third day delivery services.  Between 1990 and 1992
Oakland saw its total air cargo volumes increase by some 62 percent,
reflecting the success of the new cargo service.  These new air
cargo services represent significant components in the future growth
of air cargo activities at Oakland Airport.  The Port expects these
two sectors to continue to expand, accounting for much of the
previously unforeseen growth.  In addition, the Port expects to see
significant growth in international all cargo activity, adding
further optimism to the forecasts.

     The Port of Oakland's Updated Air Cargo Forecasts report dated
May 11, 1993 predicts a 10 percent annual growth rate for air cargo
tonnage between 1992 and 2002, and the report's authors (Port of
Oakland and P&D Aviation) predict that air cargo activity may
continue to grow at an annual rate of 10 percent until the year
2010.  This growth rate produces a forecast of over 2 million total
tons of cargo in the year 2010 for Oakland.  This revised forecast
is displayed in Exhibit 5.15 below.




5-14




MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


     The revised forecasts for Oakland do not represent a shift in
regional trends, but rather a significant change in the operational
characteristics of the cargo carriers which serve Oakland.  Several
carriers have recently instituted 2nd and 3rd day air delivery
service, and have created a new market for this service.  In
addition, a number of carriers have begun offering distribution
services to manufacturing companies, thereby creating an additional
market which did not previously exist.  Given the success of these
new markets, the carriers" plans to expand them, and the Port of
Oakland's commitment to serve the carriers, the revised cargo
forecasts for Oakland are included in this RASP as a guide to long
range planning.  The Port, in cooperation with the carriers, is
currently planning for the cargo processing facilities needed to
accommodate these forecasts.

5.3    GENERAL AVIATION FORECASTS

Summary

    The general aviation forecasts are based on an analysis of
historical trends in the general aviation sector and recent data on
number of pilots and their flight activity in California. The
analysis of the long-term historical trends in the number of active
student, private and commercial pilots shows that the rapid growth
in general aviation activity in the late 1960s and the subsequent
decline in the early 1980s appear to be largely a consequence of the
government-subsidized flying under the GI Bill flight training
program, that provided financial support to allow veterans to obtain
a commercial Pilot certificate,.  More recently, the growth in the
demand for airline pilots has fueled a new growth of pilots
progressing Through  the sequence of student, private, and
commercial pilot, as part of obtaining an airline transport
certificate.  However, the number of new student pilot certificates
issued each year cannot be explained entirely by those seeking
future employment as professional pilots.  Rather, there appears to
be a slight resurgence in interest in flying for non-professional
reasons.

     Underlying the changing pattern of pilot activity has been a
significant shift in demographics, that produced a decline in the
number of people in the younger age groups that coincided with other
factors tending to reduce flying in the early 1980s.  As the growth
in the number of people in their late teens and early twenties
resumes during the coming decade, there is likely to be a new wave
of entering pilots.

     Analysis of the California pilot activity data developed two
cohort models that explained the changing composition of the pilot
population, as the different age groups grow older. ["Cohort" models
analyze population trends by observing groups of people (referred to
as 'cohorts') over time.  These groups, or "cohorts", are usually
age groups (such as people ages 16-24, 25-34, etc.)]. It was found
that the flying activity of a given age cohort tended to change in a
consistent way as the cohort aged.  Thus, by predicting the future
numbers of entering pilots in the youngest age groups, it appears
possible to forecast fairly accurately how many will still be flying
at any time in the future, and how many hours per year they will
fly.  Analysis of national data on pilot certificates issued
suggested that the number of new student pilots per 10,000
population is likely to remain fairly stable, with a slight growth. 
Similarly, the number of new commercial pilots is likely to be
closely ed to the growth in the demand for airline pilots, which can
be derived from FAA forecasts of future commercial air traffic.

     Using this approach, high and low growth scenarios for entering
pilots were defined, and the corresponding increase (or decrease) in
total hours flown, and hence aircraft operations, was derived. 
These show a growth in aircraft operations in the MTC/ABAG region
between 1990 and 2010 of between 6 percent and 37 percent.

    The number of based aircraft was forecast by a similar process
that examined the attrition rate at which existing aircraft are
retired from the fleet and the rate at which new Aircraft are added. 
The latter t has changed significantly over the past two decades,
and thus high and low scenarios for the rate of new aircraft
acquisition were developed. The low scenario is based on a
continuation of current rates, while the high scenario is based on
the growth in flying activity projected by the cohort models. The
low growth scenario forecast a slight reduction in the based
aircraft fleet by the year 2010 of around 3 percent, while the high-
growth scenario projected an increase of about 25 percent to around
8,700 aircraft.

     The fairly wide range of the forecasts for both aircraft
operations and based aircraft in the region by the year 2010
demonstrate the sensitivity of the complex dynamics of the general
aviation sector to what may appear to be relatively minor shifts in
participation levels.  This results both from the very long active
life of an aircraft, as well as the fact that a pilot learning to
fly today could still be flying four or five decades hence.

Introduction

     In contrast to air carrier and air cargo activity, which have
shown steady growth over the past ten years, the pattern of general
aviation (GA) activity has been one of stagnation or The central
issue for the development of forecasts of future GA activity is
whether this stagnation will continue, whether an accelerating
decline will set in, or whether recent trends will reverse and
growth will once again resume.  This cannot be resolved by analyzing
past aggregate trends.  Instead, an attempt must be made to
understand the dynamics of the changes in the general aviation
sector over the past decade, and the implications of those dynamics
for the future.

     General aviation activity depends on two or three related
factors: the supply of pilots and the' amount they fly, and the size
and composition of the aircraft fleet.  Although data on pilot
activity is not readily available at the level of the Bay Area, much
less within individual counties, an extensive database on active
pilots and hours flown has been assembled at the state level by the
COMSIS Corporation (1990).  Under the assumption that Bay Area
pilots are not significantly different from those in other areas of
California, this can be used to develop projections of future growth
(or decline) in total hours flown.

   In order to translate a forecast of hours flown into more
conventional  measures of g aviation activity, such as based
aircraft or operations, projections are needed of the future of
hours flown per based aircraft, and aircraft operations per hour
flown.  Since these ratios are likely to vary considerably by
aircraft type, it is desirable to develop these projections by broad
category of aircraft to allocate the projections of hours flown to
each category of aircraft.

5.3.1   Forecasts of Pilot Activity

     Data on the number of active pilots and their annual hours
flown is available from pilot medical records (COMSIS, 1990), by the
class of medical certificate.  The class of medical certificate
usually corresponds to the type of license held, as follows:

             Medical Class 1 - Airline Transport Pilot License
             Medical Class 2 - Commercial Pilot License
             Medical Class 3 - Private or Student Pilot License

     Some pilots have a higher class of medical certificate than
required for their license, whether out of aspirations for obtaining
a higher class of license in the future or a desire for a more
rigorous medical examination.  Since this is likely to be correlated
with the amount of flying, using medical class to measure hours
flown may tend to underestimate the average number of hours flown by
pilots with a given class of license.  However, assuming that this
tendency is fairly stable over time, it should not affect
projections of the growth rate in number of hours flown.  The trend
over the 10 year period from 1978 to 1988 in the number of active
pilots in the state by class of medical certificate and class of
pilot license is shown in Exhibits 5.20 and 5.21. Since 1980, the
numbers of student, private and commercial pilots have all shown a
steady decline.  Interestingly, the number of pilots holding a
flight instructor rating has remained fairly steady, in spite of the
decline in student pilots.

National Trends

     In order to better understand these patterns, it is helpful to
examine the broader national context.  National data on the number
of student and private pilots are available from the FAA annual
Statistical Handbook and U.S. Civil Airmen Statistics.  Data on the
number of active pilots in each class are available from 1952, as
shown in Exhibit 5.22. It can be seen that the number of active
student pilots at year end rose steadily during the 1950s and 1960s,
reaching a peak in 1968.  There was then a slow decline until 1975,
then steady growth until a second peak in 1979.  The number
thereafter declined sharply until 1983, then, with minor
fluctuations, grew very slightly until 1986, thereafter declining
until the present.

     The number of active private pilots at each year's end follows
a similar pattern, with the peaks shifted a year or more later, as
would be expected, due to the time required to complete student
flight-training.  The apparent sharp fluctuations in the mid-1950s
are believed to be due to changes in the FAA definition of active
pilots, rather than any change of activity.  An active pilot is
currently defined as a pilot with a valid medical certificate. 
Private and student pilots must renew their medical certificates
every two years, commercial pilots every year, and airline transport
pilots every six months.  The slight growth in student pilots in the
mid-1980s does not appear to have arrested the decline in active
private pilots during the decade.  There also appear to be two
distinct reductions in the number of active private pilots, one in
1973 and one in 1981.

   The former may well be due to the fuel shortage in that year,
while the latter may reflect the effect of the 1981 air traffic
controllers' strike, which restricted the access of general aviation
aircraft to busy airports or other air traffic control services
(such as instrument operations in controlled airspace) for a while.

     The pattern of active student pilots is reflected in the number
of student pilot certificates issued each year, as shown in Exhibit
5.23 the surge in student pilots immediately before and after World
War II is dramatic, reaching an all-time high in 1947.  Although
military pilots do not need to be licensed by the FAA, it is likely
that many military pilots will be inclined to obtain a civil
certificate on leaving the service.  Of particular significance is
the relationship between the number of student and private pilot
certificates issued in a given year, and the number of active
student and private pilots at year end.  The number of student pilot
certificates issued and the number of active student pilots at year
end is shown in Exhibit 5.24. The number of active pilots for each
year is approximately 1.6 times the number of certificates issued in
that year, suggesting that on average each student takes about 1.6
years either to progress to the private pilot certificate or become
inactive.  However, since the definition of active pilot status is
having flown within the past two years (since the only check occurs
when the medical certificate is renewed every two years), in
practice, many "active" student pilots may have already given up
flying.

    The relationship between the number of students and the number
of pilot certificates issued is shown in Exhibit 5.25. This
indicates that only about 40 percent of those issued student pilot
certificates eventually progress to a private pilot certificate. 
From 1966 to 1988, on average, about 16 percent of student pilots
obtain their private pilot certificate within one year, while 19
percent take between one and two years, and 6 percent take longer
than two years.  From 1966 to 1979, 22 percent of student pilots
obtained their private pilot certificate within one year, while a
further 17 percent took longer than one year.  From 1980 to 1988,
these percentages changed to 14 percent and 30 percent,
respectively.  Thus it would appear that recent trends are for a
higher proportion of those issued student pilot certificates to
obtain their private pilot certificate, but to take longer doing so. 
This most likely results from the ending of the GI Bill flight
training program discussed below.

     The number of active student pilots in each age group is shown
in Exhibits 5.26 and 5.27. It can be seen that the reduction after
1980 is less marked for student pilots older than 35, and there is
no apparent reduction in student pilots for the two oldest age
groups until 1990, when all age groups show a noticeable drop.  Note
the rise in the numbers of student pilots in the youngest age group
from the ' mid-1960s through the early 1980s, corresponding to the
period of the GI Bill flight training program.  It is not clear
whether the sharp increase in student pilots over age 60 in 1965 and
1966 is a data anomaly, or also results from the inception of this
program.  The corresponding data for private pilots are shown in
Exhibits 5.28 and 5.29. These show two very different patterns.  The
four-age groups younger than 35 appear to grow and decline more or
less together, while the age groups older than 40 show a cohort
effect, with the

number of pilots in each age group rising to a peak in successively
later years, as the cohorts age.  The age group from 35 to 39
appears to show a transition effect, neither reflecting the pattern
of the younger age groups, nor showing the clear cohort effect of
the older age groups.

Effect of the GI Bill Flight Training Program

     It is clear from an examination of the foregoing trends that a
significant factor in the number of new pilots during the late 1960s
and '70s was the flight    training opportunities presented by the
Education and Training Program of the federal Veterans
Administration (available to veterans under the so-called "GI
Bill").  Under this program, veterans could obtain financial
assistance to pursue flight  training at an approved school, either
for vocational purposes (i.e., a career as a commercial pilot) or
"ancillary to the pursuit of another vocation".  For most of its
life, the program paid 90 percent of established charges for tuition
and fees for training leading to a commercial pilot's certificate. 
To be eligible, veterans had to possess a valid private pilot's
license and meet the medical requirements for a commercial pilot's
license (i.e., a class 2 medical certificate).

     While these benefits did not cover student pilot training
(except under some rather limited conditions), the value of the
benefits once a veteran obtained a private pilot certificate were
substantial.  Apart from paying most of the cost of some 200 hours
of additional flying necessary to obtain a commercial certificate,
including experience with aircraft with such advanced features as
retractable landing gear and variable pitch propeller, the training
allowed veterans to obtain additional ratings, such as an instrument
rating, that would be of value even if they never flew for
commercial purposes.  It could be expected that many veterans would
be willing to pay for their student pilot training out of their own
pockets, in order to take advantage of this program of advanced
training.  'This would be particularly true for veterans who had no
interest (or reason) to take other forms of education or training to
use up their entitlement, such as veterans who already had a college
degree or professional qualifications.  A veteran was eligible for
1.5 months of full-time education or training for every month of
service, to a maximum of 36 months.  This entitlement was reduced by
one month for each payment to the veteran for flight g of an amount
that varied from $175 in 1971 to $317 by 1981.  At the rate in
effect in 1978, one month of entitlement per $288, a veteran with
the maximum 36 months of entitlement could cover $11,500 in 
training expenses, which could easily pay for the necessary 200
hours of flight time, even allowing for other instructional costs. 
Furthermore, in some cases the training costs were tax deductible,
thus providing additional incentives to fly under this program.

     Data on the number of veterans who took advantage of this
program is somewhat obscure, but limited statistics are available
from various publications of the Veterans Administration (VA) and
others. relating to the VA programs.  The total number of veterans
who participated in the flight training program under the GI Bill
from its inception after World War H through December 1977 was about
244,600 (VA, 1980).  Of these, about 101,500 participated between
June 1966 and June 1973 (Jobs for Veterans National Committee,
1974), while a total of 166,186 enrolled

in the program between 1967 and its termination in 1981 (information
provided by VA personnel).  At the end of September 1977, there were
about 16,300 veterans in the program (VA, 1978).  By the late 1970s,
concern was being expressed that the program was largely funding
'avocational' rather than vocational  training (Congressional Budget
Office, 1978), and in 1980 Congress reduced the benefits to 60
percent of training. expenses for courses commenced after September
1 of that year, and the following year terminated the flight
training program effective October 1, 1981, except to permit those
already enrolled in a course to complete their training. By 1982 the
number had  reduced  to  about  2,200  and  by  1994  it  was  down 
to  about 200.

     From 1967 to 1981, approximately 790,000 private pilot
certificates were issued, while during this period 166,186 veterans
enrolled in the flight training program.  Thus it would appear that
veterans undertaking flight training supported by the GI Bill might
have accounted for about 21 percent of the private pilot
certificates issued prior to 1981.  Clearly these numbers only go
part way toward explaining the changes in the number of student
pilots during the past three decades.  Presumably, there was also
some attrition of veterans who obtained a private pilot certificate
intending to pursue further flight training, but never did, so the
percentage of new private pilot certificates that might be
attributed to the GI Bill could be somewhat higher.

     There are at least two other possible factors related to the
Vietnam war  that might explain the dramatic increase in student
(and consequently private) pilots from 1963 to 1968.  One is the
number of military pilots being trained during the build-up for the
war, who subsequently (or simultaneously) obtained a civil
certificate, as well as other military personnel with increased
opportunity to learn to fly.  The second is an increased interest in
learning to fly by young men facing the draft, whether out of a
genuine desire to serve in air combat or more a desire to avoid
infantry duty.  In 1964, 9 percent of active student pilots were
under age 20, while 24 percent were aged 20 to 24.  Two years later,
the number of active student pilots under age 20 had more than
doubled to 16 percent of all active student pilots, while the number
of those between age 20 and 24 had increased by 46 percent to almost
42,000, accounting for 25 percent of all active student pilots. 
Over this two-year period, the number of active student pilots
between the ages of 35 and 59 increased by only 3 percent from
36,800 to 38,000.

Student and Private Pilot Certificates Issued

     The number of active student pilots in the younger age groups
at a national level has been relatively constant since 1983, as
shown in Exhibit 5.22 above.  However, the size of the population in
each age group has also been changing over time, as shown in Exhibit
5.30. When adjusted for this change in population size' the number
of new student pilot certificates issued per year per 10,000
population is shown in Exhibit 5.31.The effect of the GI Bill
discussed above can be clearly seen, particularly the effect on the
two age groups between 20 and 29.

     Since 1982, the trend in new student pilots starts has become
much more stable, with the participation rates of the age groups
from 20 to 39 showing similar rates and a steady decline to between
about 5 and 6 per 10,000 by 1990, while the participation rate of
those under age 20 was fairly steady from 1982 to 1985, at around 5
per 10,000, and has risen since then to between 6 and 7 per 10,000. 
The noticeable increase in the participation rate of the age group
from 20 to 24 since 1988 may be indicative of a similar trend. 
Since the participation rate of the youngest age group has been
historically lower than for the older age groups (at least since
1970), there appears to have been a recent change in the 
attractiveness of learning to fly for this age group.  One possible
explanation is the recent increase in the number of commercial
aviation jobs indicated by the increase in commercial and airline
transport certificates issued as shown by Exhibit 5.32. While the
trend is too recent to allow any reliable statistical analysis, and
the historical data are too confused by the effects of the GI Bill,
this may allow some reasonable assumptions of the future direction
of this trend, based on the expected future needs of the. airline
industry.  This is discussed further in the section on growth
projections.

    The number of new private pilots can be computed from the
relationship discussed above, that expresses the number of new
private pilot certificates issued in any year in terms of the new
student pilot certificates issued in the preceding years.  It is
assumed that the aggregate relationship is true for all age groups. 
In order to determine the number of active student and private
pilots in any year, it is also necessary to know the pilot attrition
rate.  Statistical analysis of national age group data resulted in
models of student and private attrition that show that student pilot
attrition in any year is about 34 percent of the student
certificates issued two years before plus 12 percent of those issued
in the preceding two years.  Private pilot attrition in any year is
about 9 percent of the active private pilots two years before.

Commercial and Airline Transport Pilots

     The number of active pilots holding commercial and airline
transport certificates is shown in Exhibit 5.33. 'Mere has been a
steady decline in the number of active commercial pilots since the
early 1970s, following a period of rapid growth in the late 1960s,
although the decline appears to have bottomed out in 1988 and there
has been a moderate growth in the last two years.  In con=t, the
number of active airline transport pilots has grown steadily, and by
1990 was approaching the number of active commercial pilots.

     The trends in the number of active commercial pilots by age
group are shown in Exhibit 5.34 and 5.35. It can be seen that there
has been a resurgence of active pilots in the younger age groups
since 1986, reflecting the recent increase in the number of
certificates issued, shown in Exhibit 5.32. Also noteworthy is the
significant increase in active commercial pilots over age 60,
possibly reflecting a growing number of retired airline pilots, who
no longer elect to (or can) maintain the more rigorous Class I
medical certificate requirements for an airline transport
certificate.  The recent trends in the estimated number of
commercial certificates issued to pilots in the two age groups from
20 to 29 are shown in Exhibit 5.36, together with the number of

active pilots in the corresponding age groups.  It can be seen that
by 1990 the number of commercial certificates issued each year to
pilots in the age group between 20 and 24 had reached about 40
percent of the number of active pilots in the group at the end of
the year.  It can also be seen that the average age at which
commercial pilots are gaining their certificate is increasing,
possibly reflecting the greater time required to accumulate the
necessary flight  experience without the financial support of the GI
Bill program.  It may also affect changes in the age at which
military pilots are leaving the service, as discussed below.

     Many pilots acquiring commercial certificates are doing so en-
route to an airline transport certificate.  The recent trends in the
estimated number of airline transport certificates issued to pilots
in the three age groups from 20 to 34 is shown in Exhibit 5.37.
There appears to be,- a 5 to 10 year lag between pilots gaining
their commercial and airline transport certificates, ,suggesting
that almost 85 percent of those pilots gaining commercial
certificates between 5 and 10 years.ago have progressed on to
airline transport certificates.  Unfortunately, the effect of the GI
Bill program, which produced a large number of pilots in the early
1980s holding commercial certificates, but with only avocational
interests in flying, makes the true magnitude of this effort
difficult to analyze.

    The number of military pilots leaving the service has influenced
the supply of commercial and airline pilots, and will continue to do
so in the future.  Data on this has also been difficult to obtain,
particularly the number of such pilots who possess civil
certificates or who take up professional flying careers upon leaving
the service. The Air Force has been undertaking a budgetary program
to reduce the number of pilots, and estimates that some 3,800 pilots
worldwide were separated in fiscal year 1992.  That number is then
expected to drop to about 2,400 in fiscal 1993 and 1,400 to 1,500
per year thereafter.  Since not all of these will continue flying
professionally, they are not likely to form a very large fraction of
the 15,000 or so commercial certificates currently being issued per
year, although they may well form a larger share of those who
progress to an airline transport certificate.

Private and Student Pilots

     The trend in the number of active pilots in California holding
a Class 3 medic- al certificate, by age, is shown in Exhibits 5.38
and 5.39. It can be seen that  the age composition of the active
pilot population has been changing over time in the same general way
as the national data for student and private pilots, although the
decline in the number of active pilots in the early 1980S does not
seem as pronounced.  As can be expected, a drop in the number of
younger pilots in one year will show up as a reduction in the number
of pilots in progressively older age groups in subsequent years.  In
particular, it can be seen that the number of pilots aged 15 to 19
declined until 1984 and has been rising since 1985. The number of
pilots aged 20 to 24 continued to decline after 1985, presumably due
to the delayed effect of the decline in the number of younger pilots
five years earlier.  The number of pilots in each age range
increased in successive age groups, reached a peak somewhere between
age 30 and 45 and declined

5-23

MTC Regional Airport System Plan Update
Chapter 5: Aviation Demand Forecasts                September 9, 1994


thereafter, with the peak age group becoming older over time, as
that group of pilots aged.  However, there was an interesting
anomaly with the number of pilots aged 60 to 64, which increased
throughout most of the period, reaching a level in 1987 higher than
the number of pilots in the previous age group five years earlier.

     The average hours flown by pilots in each age group is shown in
Exhibits 5.40 and 5.41. In contrast to the number of active pilots,
this appears to be quite stable over time, with some minor
fluctuations. The variation in the average hours flown by the two
oldest age groups is possibly due to effects of the smaller sample
size involved. There appears to be no basis from the data for
assuming that the hours flown by each age group will change
significantly in the future from the average values given in Table
1.

Cohort Analysis

     Projections of the number of active pilots in future years can
be obtained from an analysis of the change in the number of pilots
in each five-year cohort as that group ages.  The ratio of the
number of pilots in each age group to the number in the previous age
group five years before is shown in Exhibits 5.42 and 5.43. With the
exception of the group aged 20 to 24, this ratio appears fairly
stable over time. The change in the average ratio for successive age
groups is shown in Exhibit 5.44.


Commercial Pilots

     A similar analysis was performed for pilots holding Class 2
medical certificates. The number of active pilots in California in
successive age groups is shown in Exhibits 5.45 and 5.46. Compared
to student and private pilots, there is a much lower proportion of
pilots in the 15 to 19 age group, and the number of pilots in each
age group increases significantly until the mid thirties.  This is
perhaps not unexpected, given the training requirements and career
orientation of the commercial license.  Also clearly apparent from
Exhibit 5.45 is the significant drop in the number of active
commercial pilots in all age groups below 35 between.1978 and about
1985, beginning somewhat earlier in the older age groups.  This
pattern is quite different from the cohort effect observed with
student and private pilots, and also apparent to a lesser extent
with commercial pilots above age 40, in which trends in one age
group appear five years later in  succeeding age group, and appears
to be largely due to the ending of the GI Bill flight g program.

     The average hours flown by pilots in each group is shown in
Exhibits 5.47 and 5.48. These values appear less stable over time
than was the case for student and private pilots, with the average
hours flown by pilots in the age groups from 30 to 45 tending to
increase over time.  The age group from 65 to 69 also shows a
distinct increase in hours flown over the period.  This

increase may be a compensating effect for the reduction in the
number of younger commercial pilots, with the older pilots flying
more to meet the demand for commercial flying activities.

Cohort Analysis

     The ratio of the number of active class 2 pilots in each age
group to the number in the previous age group five years before is
shown in Exhibits 5.49 to 5.50. With the exception of the two groups
between 20 and 29, these ratios appear to show A fairly steady
change over time.  The change in the ratio for the younger age
groups can be explained by the drop in the number of active pilots
in each age group discussed above.  The average change in the number
of pilots in each age group compared to the previous age group five
years previously is shown in Exhibit 5.52.


Growth Projections

Forecasting the Trends in Entering Pilots

     The national data on the number of student pilot certificates
issued per 10,000 population, shown in Exhibit 5.31 above indicates
that the participation rate for the age group 16 to 19 has been
increasing in recent years from around 5 per 10,000 to around 7 per
10,000.  From 1985 to 1988, the number of active medical class 3
pilots in the same age group in California grew from 5.04 to 6.37
per 10,000 population, compared to a national average for active
student pilots that grew from 8.9 to 10.2 per 10,000 population. 
The difference is most likely due to the number of student pilots
with Class I or Class 2 medical certificates, due to plans for
professional flying careers.  If the growth Class 3 participation
rates in California continued at the same rate until 1990, as
suggested by national data, the. rate then would have been around 7
per 10,000.

     This suggests that a low growth scenario might to assume that
the current participation rate of the youngest Class 3 pilots
continues at a constant level of 7 per 10,000 in the future.  A high
growth scenario could assume that the increasing trend in the
participation rate for the youngest age group observed since 1985
continues until 1995 and then levels out.  This would result in an
increase in the participation rate to around 10 per 10,000
population, a level comparable to that observed in the early 1970s.

     Predicting the growth in the number of commercial pilots in the
entry age range (20-24) is more difficult, since this is presumably
driven by the prospects for a professional flying career.  This is
likely to be driven by the future balance between demand and supply
of professional pilots.  Since a high proportion of new commercial
pilots are apparently progressing to airline transport certificates,
it might be expected that the future growth in new commercial
certificates might reflect the future demand for airline pilots. 
Fortunately, this is subject to analysis.  The future number of
airline pilots will depend on the amount of airline flying, which in
turn depends on

are projected to be 9 percent below 1990 levels.  The net effect is
to give an increase in total hours flown per year between 1990 and
1995 of about 4 percent, with the growth rate slowing in subsequent
years, until by 2010 the total hours flown per year are projected to
be approximately 6 percent higher than in 1990.

     Under the high-growth scenario, there is much more rapid growth
in hours flown by commercial pilots, particularly in the later years
as the higher number of entering pilots appear in older age groups. 
By 2010, hours flown by commercial pilots are projected to be 66
percent above 1990 levels.  The hours flown by private and student
pilots under this scenario remain constant until 1995, then show a
slow but increasing growth until by 2010 they are approximately 6
percent higher than in 1990.  The net effect is to give a steadily
increasing growth in total hours flown of about 1.4 percent per year
until by the year 2000 the total hours flown are projected to be 15
percent above 1990 levels.  The net growth rate is projected to
increase thereafter to about 1.8 percent per year, giving a
projection of total hours flown in 2010 some 37 percent above 1990
levels.

Comparison Between California and the Bay Area

     Since the forecasts have been developed at a state level, due
to the lack of suitable data at a more local level, it is
appropriate to ask how similar the general aviation activity in the
Bay Area is to that of the state as a whole.  A number of comparison
methods have been developed, as shown in Table 5. While the nine Bay
Area counties, perhaps not surprisingly, have fewer airports in
relation to its population than the state, the number of annual
general aviation operations per capita is quite similar to the state
average (0.49 compared to 0.52). Likewise, the number of based
aircraft per capita is slightly less than the state average (I. 17
per thousand population, compared to 1.22). The number of operations
per based aircraft is almost identical, especially for FAA towered
airports.

     The characteristics of the traffic are somewhat different,
reflecting the density of the region, and' the resulting smaller
number of non-towered airports (airports with no FAA towers).  A
much larger proportion of the general aviation activity (75 percent)
occurs at FAA-towered airports, compared to the state average (52
percent), while the proportion of the general aviation operations at
FAA-towered airports that are local is also higher than the state
average (51 percent compared to 44 percent).  This reflects the high
proportion of airports in the region that have FAA towers,
supporting training activities that would tend to use other airports
elsewhere in the state.  However, it is clear that these differences
do not suggest that the overall pattern of general aviation activity
in the Bay Area is significantly different from that of the state as
a whole.  Thus growth projections developed for the state should
also hold true for the San Francisco Bay Region.

5.3.2  AIRCRAFT OPERATIONS AND BASED AIRCRAFT FORECASTS

   During the ten-year period from 1978 to 1988, significant changes
occurred in the relationships between the number of general aviation
aircraft, the number of hours flown and the number of local and
itinerant operations.  The trends in the number of hours flown by
pilots with Class 2 and 3 medical certificates and the hours flown
by general aviation aircraft in California are shown in Exhibit
5.53. It can be seen that the two series are generally consistent. 
Allowing for commercial and private pilots holding Class 1 medical
certificates, which will increase the pilot hours flown, the number
of pilot hours flown exceeds the number of aircraft hours flown. 
This is to be expected, due to both pilots logging hours on two-
pilot flights, whether as pilot and copilot, or during flight
instruction.

     The reduction in total hours flown also reduced the number of
hours flown per aircraft, as shown in Exhibit 5.54, since changes in
the size of the aircraft fleet occur much more slowly.  The decline
in the amount of instructional flying reduced the ratio of local to
itinerant operations, with a corresponding reduction in the number
of operations per hour flown, due to the much higher number of
landings and take-offs per hour in local flight compared to
itinerant operations.  The change in the number of operations at FAA
towered airports per hour flown is shown in Exhibit 5.55, while the
change in the percentage of general aviation operations at FAA
towered airports accounted for by local operations is shown in
Exhibit 5.56. After the reduction in the first half of the 1980s,
these relationships appear to have stab at around 1.65 operations
per hour flown, with about 44 percent of these being local
operations.

Aircraft Operations Forecasts

     If these relationships remain stable, then future changes in
hours flown should produce a proportional change in airport
operations, as shown in Exhibit 5.57. Although future growth is
expected to be largely due to increasing activity by commercial
pilots, previous surveys of general aviation pilot activity (FAA,
General Aviation Pilot and Activity Survey, 1976, 1979, 1983, 1985)
suggest that the difference in operations generated per hour flown
between commercial and student/private pilots may not be great, as
shown in Exhibit 5.58. This appears to be due to an increase in the
percentage of local flights by commercial pilots, presumably due to
an increase in their role as flight instructors. However, this
illustrates the complex relationships between the relative numbers
of different types of pilot on the resulting patterns of general
aviation activity.

Based Aircraft Forecast

     In the short run, the number of based aircraft is not much
influenced by the levels of general aviation activity.  Owners are
much more likely to sell than to scrap an aircraft if they are not
flying it much, and relatively few new general aviation aircraft are
being bought, except for larger corporate aircraft.  An analysis of
the age distribution of the current based aircraft

suggests that new aircraft are being added to the fleet at a rate of
around only 0.2 percent per year.  The rate at which older aircraft
are likely to be retired (or are lost due to accidents) can be
assessed from the change in numbers of registered aircraft of the
same model year over time.  While this information is not readily
available for all aircraft types, it can be inferred from data for
Cessna 150/152 series aircraft as the 150 series model number
changed almost every year from the early 1960s until the production
was discontinued in 1977.  Since each model was given a different
designation letter (e.g. 150, 150B, etc.), the fleet attrition can
be determined from data on registered aircraft in the FAA Census of
U.S. Civil Aircraft.  Attrition of relatively new aircraft can be
inferred from data for the 152 series since it was discontinued in
1986.  The annual attrition in the number of aircraft of a given
model year as a function of aircraft age is shown in Exhibit 5.59,
together with an assumed attrition function.

Aircraft Utilization and Pilot Activity Trend 

     Using these relationships for new fleet acquisition and
aircraft attrition, the size of the Bay Area fleet was estimated
through the year 2010, as shown in Exhibit 5.60. This shows the
based aircraft fleet declining by about 3 percent by the year 2000,
leveling out between 2000 and 2005, and increasing slightly
thereafter.  The analysis does not take into account aircraft that
might be relocated to or from the Bay Area, or factors that might
change the acquisition or attrition rates in the future.  These
factors aside, the based aircraft fleet can be expected to decline
by about 2.7  percent by the year 2010.  Under the high-growth
scenario described above, this would result in an increase in
average aircraft utilization to around 205 hours per year.  Under
the low growth scenario, average aircraft utilization would increase
to about 160 hours per year.  While the latter utilization level
should present no particular difficulty, the level of 205 hours per
year under the high growth scenario corresponds to that achieved in
the late 1970s, when a large number of new aircraft were entering
the fleet.  To the extent that the growth in hours flown is being
partly driven by increasing numbers of new pilots, the flight
training schools will need to acquire new aircraft as their existing
fleets age.  The aircraft they replace will have many years of
service left, and will remain in the fleet for private or corporate
use.  Thus it appears that the based aircraft forecast may not be
independent of the pilot activity projections for the high-growth
scenario.

     A high activity growth scenario forecast of based aircraft was
prepared, assuming that the number of new aircraft entering the
fleet increased in proportion to the increase in hours flown.  This
gave the higher forecast shown in Exhibit 5.60. Under this scenario,
the based aircraft fleet grows steadily from 1990 at a progressively
increasing rate to around 8,700 aircraft by 2010.

Chapter 5: Aviation Demand Forecasts                September 9, 1994


Sensitivity of Forecast to Varying Assumptions

    The forecast growth shown in Exhibit 5.60 indicates the
sensitivity of projections of the size of the future based aircraft
fleet to assumptions about the rate at which new aircraft are added
to the fleet.  The low-growth scenario assumed that new aircraft
would be added at rate of only about 15 aircraft per year, while the
high growth scenario assumed that new aircraft would be added
initially at a rate of 1.5 percent of the current fleet (or around
100 per year), rising to a rate of 2.5 percent (or about 175
aircraft per year) by the year 2010.

     Even the high growth rate assumptions are significantly less
than the rate of new aircraft acquisition in the 1960s and 1970s,
which reached a rate of about 7 percent per year in 1978 and was
never less than about 1.5 percent.  This suggests that future growth
rates could be even higher than assumed for the high growth
forecast.

Summary of General Aviation Airport Forecasts and Findings

   -    General aviation covers many different activities that are
        influenced by very different causal factors.

   -    Expected future needs for professional pilots appear likely
        to spur an increase in the number of student pilots and
        flight training activity at a national level.

   -    Depending on the rate at which new pilots take up flying, the
        growth in general aviation aircraft operations (take-offs and
        landings) at the Bay Area airports could range from 6 percent
        to 37 percent over the next 20 years.

   -    One current general aviation aircraft fleet is significantly
        under utilized to past experience, and very few new aircraft
        are being manufactured.  The fleet size can therefore be
        expected to decline slowly in the near term.

   -    Over the long term, there could be a resurgence of growth in
        general aviation activity, particularly flight training,
        which could lead to an increase in based aircraft by 2010 of
        up to 25 percent.

   -    In spite of the recent slow decline in the number of based
        aircraft in the Bay Area, there currently exists an unmet
        demand for hangar space.  Airports lease hangars as soon as
        they become available, and owners relocate aircraft to take
        advantage of hangars that become available.

   -    While the current general aviation airport system has excess
        aircraft parking capacity, this could change if the based
        aircraft capacity at San Jose International Airport is
        significantly reduced, and any general aviation airports are
        closed.

   6    AIRPORT SYSTEM ALTERNATIVES DEFINITION

   6.1  INTRODUCTION

          The objective of defining regional airport system
alternatives is not only to identify the range of policy choices
being faced by the region, but also to provide a basis for
evaluating their feasibility as well as their possible consequences. 
The set of alternatives should offer a range of visions of the
future, defined in sufficient detail to provide a basis for
comparing them, choosing between them, and identifying the actions
needed to implement them.  While these alternatives must be founded
in what is technically possible, they should not be unduly
constrained by existing political or institutional agendas.  To
accept such constraints may result in foregoing the best long-term
solution in the interests of short-term expediency.  Rather, such
constraints should be recognized in the way the alternatives are
defined and evaluated.  The evaluation process should identify
implementation pathways which could actually eliminate current
constraints by building political constituencies for institutional
change, where such change is needed.

     Central to this approach is the requirement to quantitatively
evaluate the alternatives, in order to provide a basis for choosing
among them.

The 1990 Apogee Study

     A previous study by Apogee Research, Inc., included extensive
focus group discussions with a broad range of airport users,
operators, and the general public.  On the basis of these
discussions, six alternative strategic policy approaches were
suggested (Apogee Research, Regional Airport System Plan Update:
Summary of Findings and Policy Alternatives, December 7, 1990). 
These alternatives were considered and used in generating the actual
system plan alternatives used in the 1993 Regional Airport System
Plan Update.

     The Apogee policy alternatives listed below can be thought of
as providing a strategic perspective on the development of the
regional airport system.  While they do not identify the specific
projects and implementation actions that are necessary, they
articulate broad goals for the future of the airport system.

      No New Action -- This policy envisages a continuation of the
status quo, with no significant new capacity and steadily increasing
congestion everywhere.  Market forces would tend to shift traffic
growth from SFO to OAK and SJC.

     Centralize Aviation Activity -- This policy assumes future
growth to be concentrated at SFO, in order to minimize the spread of
adverse impacts.  Resources would be directed at improving ground
access to SFO.  Additional Bay fill to increase capacity and reduce
noise impacts would be considered.

     Limited Decentralization - This policy anticipates growth at
OAK and SJC by improving ground access to those airports.  Capacity
increases at SFO would be limited to increased operational
efficiency, improved ATC technology, and the use of larger aircraft.

     Greater Decentralization -- This policy seeks to expand
capacity at other airports in the region, including new airport
sites well outside the urban area, and limits the growth at SFO,
OAK, and SJC.

     Alternatives to Aviation -- This policy considers the
development of high-speed rail services or other modes of
transportation as a way to reduce the need for expanding airport
capacity.  Resources would be directed at developing intermodal
links, with growth of the existing airports limited by noise
restrictions and opposition to further Bay fill.

     Ground Transportation Focus -- This policy would emphasize
improving ground access to all airports and allow the growth of each
airport to be determined by market forces.

Air Carrier and General Aviation Airports

     The regional airport system is not a homogeneous set of
facilities, but rather consists of two broad categories of airports
that serve two very different types of traffic.  Of the some 30
airports in the region, a small number, currently five, serve the
needs of the commercial air carriers.  The largest, San Francisco
International, handles more air carrier traffic than all the others
combined.  While the three largest air carrier airports also serve a
varying amount of general aviation traffic, the greater number of
airports serve only general aviation      c.

   Because of the widely differing requirements of air carrier and
general aviation activity, and the implications for airport
development, it is useful to consider the two types of airport
separately when defining alternatives for a regional system.  Thus,
the complete range of system alternatives will consist of Air
Carrier Airport System Alternatives and General Aviation Airport
System Alternatives.  Of course, these two sets of alternatives
interact in some respects, and certain air carrier airport system
alternatives may be more consistent with some general aviation
airport system alternatives.  However, by evaluating each set in
terms of how well the alternatives perform for their respective
market, interaction problems can be addressed in selecting between
the alternatives in each set, once they have been evaluated.

  The following two sections describe the air carrier airport system
alternatives and the general aviation  airport system alternatives. 
Each alternative description includes a summary statement, a list of
its major elements, and a list of implications.  The implications
are explained at the end of the alternative descriptions.

6.2    Air Carrier System Alternatives

No Build Alternative

Description

    This alternative provides the baseline for comparison of the
other air carrier system alternatives.  It is based on the
assumption that no new major additional airside, landside, ground
access, or public transportation capacity is built at the five
existing air carrier airports.  It also assumes that no new major
operational actions or other airport system management actions are
taken, either by the airports, the FAA, the airlines, or other
parties.  The existing five air carrier airports would continue to
be operated and maintained, with annual funding provided to maintain
the existing airside and landside facilities, but with no
enhancement of capacity.  Growth in airport activity (passenger, GA,
and cargo) would be constrained by current airspace and the capacity
of existing facilities (including approved projects).  Alternative 1
Am assume that existing construction projects which are contained in
existing approved airport master plans, and which have received
environmental approvals, will be built.  These include the following
projects:

   1.   Extension of runway 12R-30L at San Jose (completed in 1992)
   2.   Passenger  Terminal  Expansion  at  San   Francisco   (not  
        including   improvements   contained in the SFIA Master Plan
        approved in November 1993)
   3.   Minor   Bag   Claim,   Ticketing,   Passenger   Lobby,   and 
        International   Arrival   Facility Projects  at  Oakland.  As 
        of  1993  the  bag  claim  and  international  arrival  
        improvements had been completed.

     The purpose of including the No Build action alternative is to
allow an evaluation of what would happen if demand continues but no
additional capacity is provided, and to compare this no action
scenario with alternatives which do increase capacity.  As this
alternative would include no actions to affect the air travel market
or the existing distribution of supply or demand, the airlines could
take unilateral steps under this alternative to balance supply and
demand at the five air carrier airports.  These steps could include
adjusting their schedules, fleet mix changes, and shifting their
service between the airports.  For comparison of the air carrier
system alternatives, however, these airlines' actions are not
considered in the no new action alternative.

Elements

   A.   Only currently approved projects would be developed
   B.   No other new runway capacity projects
   C.   No other new terminal capacity or other support facility
        projects
   D.   No  other  new  ground  access  or  public  transit 
        improvement  projects  designed   to   serve the airports
   E.   No regional actions to  encourage  significant  changes  in

   G.   Passenger Convenience


Airport System Management (ASAQ Alternative

Description

  The ASM alternative would seek to maximize the effectiveness of
the existing airport system without major new construction by using
a number of system management strategies aimed at matching supply
and demand and making optimum use of existing facility capacity. 
This alternative would rely on measures to increase ground side
access and public transit to airports to take full advantage of
existing runway and terminal capacity.  In order to relieve
congestion at the three major air carrier airports, some passenger
traffic would be handled at Concord and Sonoma County, and possibly
other airports in the region, within their existing capacity to
accommodate it.

  Given the current distribution of airport capacity and demand,
this alternative would inevitably result in some redistribution of
demand among airports.  This alternative could possibly result in
greater emergence of individual airport roles among the three major
air carrier airports, such as:

        SFO:  International and Tourist Traffic
        SJC: California/West Coast Corridor Traffic
        OAK: East-West Domestic Traffic

     Another possible result of this alternative could be reduced
facility duplication (eg. centralization) of certain functions at
one airport.  Typical facilities that might lend themselves to
centralization include F.I.S. (Federal Inspection Services,
including immigration and customs) and air cargo.  Present examples
of this trend are the concentration of international facilities at
SFO and overnight air cargo activity at OAK.

     Air Carrier Airport Master Plans Alternative

Description

          This alternative would meet identified future demand by
expanding airport system capacity as proposed in the most recent
individual airport master plan concepts.  Capacity improvements to
the airside, landside, ground transportation, and public transit
systems would be built consistent with those updated master plans. 
According to those currently proposed master plans (OAK and SJC)
regional air passenger market shares would shift as follows:

MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


Potential Shift in Regional Passenger Market Share

Airport           1990 Market Share        2010 Market Share

SFO                    70%                      61%

OAK                    14%                      16%

SJC                    17%                      23%


*  Oakland's 2002 airport development program would result in a 16%
   market share for Oakland in that year.

     One function of this alternative will be to evaluate whether
the individual airport master plans will efficiently accommodate
regional air travel demand from a capacity and environmental
perspective.

Elements

   A.   Increased Runway Capacity
        *    Extension of Runway 11-29 at Oakland to 11,600 feet
   B.     Increased Terminal Capacity
        *    New international terminal at SFO

        *    Airline support facilities
        *    Airport support facilities
        *    Fuel facilities
   D.   Ground Access/Public Transportation Improvements at SFO, OAK,
        SJC
        *    Improvements to freeways, interchanges, and other
             surface streets serving airports
        *    BART extension to SFO

Airport System Optimization Alternative

Description

     This alternative would meet forecast regional passenger demand
by construction of some new capacity, but would depart from
Alternative 3 by seeking to optimize the performance of the system
as a whole.  This alternative would include redistribution of
regional passenger traffic to optimize the existing airport system
(as well as develop new ones) and better distribute supply according
to the regional distribution of demand.  Among the major factors
considered in optimizing the airport system are:

        *    Passenger convenience 
        *    Airspace utilization 
        *    Airport ground access 
        *    Environmental impacts 
        *    System cost

     There are two sub-alternatives for accomplishing this: (1)
major regional airport growth would be either focussed at SFO, OAK
and SJC; or (2) future growth would be decentralized (providing for
growth at a fourth major air carrier airport in the region).  The
focused concept would add significant capacity at the existing
airports by construction of new runways at OAK and SJC.  This
alternative could result in the following redistribution of regional
passenger market share: SFO: 50% OAK: 25% SJC: 25%.  The
decentralized concept would include construction of a fourth major
air carrier airport at either Travis AFB, another existing airport,
or at a new site.  This option would also result in a major
redistribution of regional passenger market share.  Included as a
possible additional element of this concept would be the development
of  additional commuter airline service at Concord, Sonoma County,
and other outlying GA airports.

New Technology Alternative

Description

     This alternative would focus on new air and rail technology
alternatives to supplement the existing airport system.  This
alternative includes both aviation and non-aviation technology.

Elements

   A.   Construction of high-speed ground transportation (primarily
        for intra-California  Corridor Traffic), such as conventional
        rail, MAGLEV, or other technology.

     This element would reduce demand for air travel by diverting
air passengers to the new ground transportation mode.

   B.   Application of Tiltrotor aircraft technology
   
     This element would also reduce conventional air travel demand
by diverting air passenger traffic away from traditional air
transport.  This element is primarily seen as an alternative for the

shorter haul air traffic routes, such as those under 500 miles. 
This element could also require facility improvements at reliever
airports served by tiltrotor aircraft.

6.3     General Aviation System Alternatives

No Build

Description

   The No Action general aviation alternative provides the baseline
for  comparison of the others, and would consist of no increase in
capacity at any of the  general aviation airports.  Total regional
airport system capacity would be limited by existing airport
facilities at each airport.  Existing general aviation airports
would, however, be maintained to provide safe, functional
facilities.

Elements

   A.   Maintain existing airport facilities
   B.   Protect airport from encroachment by adjoining community:
        *    Maintain/enhance land use compatibility
        *    Maintain height hazard/safety zoning and planning

Implications (see also Section 6.4 - Discussion of Implications)

   A.   Capacity and delay

General Aviation Airport Master Plans

Description

     This alternative would meet identified future demand by
developing the general aviation airport system as proposed by the
current individual airport master plans.  This alternative would
provide a full range of GA support services, and would have all
necessary navigational aids and instrumentation to provide for the
pilot training needs of the region.  These airports could provide
"reliever" facilities and services to handle displacement of general
aviation activities at the large air carrier airports such as SFO,
OAK, and SJC.  Although the existing general aviation    airport
master plans are prepared independently from the air carrier airport
master plans, one of the critical regional roles which the GA
airports play is as "relievers" for the air carrier airports.  As
passenger and cargo activity increase at the constrained air carrier
airports, the relievers are planned to accept certain  types of
general aviation activity which is no longer appropriate for the 
large commercial airport  types. These activities may include
housing based aircraft and fixed base operators (FBO's), aircraft
maintenance, flight service stations, and flight training, among
others.  In addition, this alternative could allow for selected GA
airports to be used to meet demand for decentralized commuter
activity close to users homes.

Elements

   A.   Develop facilities at selected airports to support these
        activities
        *    Runways/taxiways
        *    Apron/aircraft parking/hangars
        *    Instrumentation/navigation 
        *    Lighting, FBO facilities, etc
   B.   Develop facilities for displaced recreational GA at selected
        airports

Implications  see also Section 6.4 - Discussion of Implications)

   A.   Funding of improvements
   B.   Airport/community compatibility
   C.   Environmental impacts


General Aviation Airport System Optimization

Description

   This alternative would expand certain existing GA airports and
develop new GA airports on the periphery of the urban area in
locations where land use compatibility and aviation safety problems
can be avoided or minimized.  Because remote sites would be
preferable, this

     6-11
     
     


MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


alternative could also involve improvements to local streets and
highways to provide ground access to the new airports.  Supporting
infrastructure, including sewer, water, power, aviation fuel, etc.,
would also be needed.  These new airports could also support limited
passenger service by commuter airlines.

     By locating new GA capacity at the edge of the urban area where
community impacts can be minimized, this alternative could provide
for the relocation of existing GA activity from close-in urban
airports, which are either threatened due to existing impacts on the
surrounding urban community or pressured by expanding air carrier
passenger and cargo activity.  An example of this concept would be
accelerated development of the improvements planned at Byron
Airport.

Elements

   A.   Select sites and develop new GA airports in compatible
        locations
   D.   Provide sufficient facility capacity for future GA demand as
        well as relocated GA from air carrier and other close-in GA
        airports
   C.   Develop new facilities at specialized airports for
        training/business aviation activities  and to relieve air
        carrier airports
   D.   Acquire sufficient property and  ensure  land  use 
        compatibility  to  protect  airport  from possible future
        urban encroachment
   E.   Restrict further investment  at  airports  with  little 
        likelihood  of  achieving  community acceptance

MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


6.4    Discussion of Implications

     The implications listed under each airport  system alternative
are described below.  Each list represents some of the major
implications identified.  The lists were prepared in part to help
identify the range of criteria to be used in evaluating the airport
system alternatives.

Runway/airspace congestion and delay

     This implication relates to how well each alternative meets
existing and future demand.  Alternatives which do not provide
capacity improvements sufficient to meet forecast levels of demand
may result in significant congestion and delay on runways, taxiways,
and apron areas, in terminal facilities, on the landside of the
terminals, or elsewhere.  Alternatives which do not account for the
structure and capacity of the regional airspace may create airspace
conflicts, with related safety and delay implications.  These
implications are discussed separately below.

Airport ground access constraints

     Ground access to the region's airports is becoming an
increasingly complex issue.  Future increases in air travel demand
at the five air carrier airports will increase the already heavy
strain on the region's existing ground transportation system.  At
certain locations near the largest airports, peak hour congestion
and delay creates significant inconvenience to air passengers. 
Growing uncertainty about how long it will take to reach the airport
requires passengers to plan greater and greater lead time before
flight departures.  The growing problem with airport ground access
results in passenger inconvenience, decreased productivity,
inefficient use of the airport system, and regional environmental
impacts.  Some of these related implications are also discussed
below.

Environmental Impacts

     All of the airport system alternatives will cause some adverse
impacts on the environment.  Alternatives which provide new
facilities to accommodate airport growth will have direct on-site
impacts and impacts such as air quality and noise from the operation
of a larger and busier system.  Alternatives which redistribute air
traffic among the region's airports may reduce noise in one area
while increasing it in another.  The severity of this noise impact
will be related to factors such as the type, density, and location
of land uses near the airports.

     Those alternatives which do not provide for growth, or which
provide insufficient capacity to meet future demand, may cause
indirect environmental impacts resulting from airport congestion and
delay and increased automobile travel to airports.




     6-13
     
     


MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


Air Fares (supply vs demand)/Airline competition

    One of the potential implications of differing approaches to
meeting future demand may be the effect on air fares and airline
competition.  Given a free market, if demand far exceeds supply, the
price will rise until a balance of these two factors is achieved. 
In addition, the lack of sufficient terminal space can effectively
block out new carriers, reducing competition among airlines.  One of
the regional implications of the system plan is therefore related to
the potential effect on competition and ticket prices, and the
related issue of equitable access to the nation's air transportation
system.  Lack of airline competition could also affect level of
service and ticket prices.

Safety

     One of the implications of regional airport system development
decisions will relate to aircraft safety, both on the ground and in
the air.  Growing public concern over safety is in part related to
increasing congestion at airports and in the airspace around them. 
As congestion increases, the potential for pilot, air traffic
controller, air navigation, communication, and other system error
increases.  With this comes a growing potential for accidents. 
Regional airport system alternatives that do not effectively address
existing and future airport or airspace congestion may contribute to
this safety concern.

Timing of improvements or other actions

     Timing issues relate to the length of time it may take to
complete site selection processes, environmental approvals,
construction projects, FAA research activities and other actions,
development of new technologies, creation of necessary
organizational structures, and development of the political will of
the region to take action.  For example, selection of a site and
construction of a new air carrier airport may ease the region's
congestion, but could easily take 10 years or more to complete.  If
this alternative were selected in the plan, it may be also necessary
to include interim measures to meet growing demand until such time
as, the new airport can be built and put into service.

     FAA capacity enhancement measures and new technology may also
be elements of the regional plan, but there may be considerable time
before they are implementable.  Again, the timing of these elements
in the regional airport system plan is a critical aspect in
evaluating how well they will serve the region.

Airport/airline cooperation

     Several- elements of the alternatives will require the
cooperation of both airports and airlines for their implementation. 
Examples include shifts in aircraft fleet mix and changes in airline
schedules.  As such elements are further defined and evaluated in
the planning process, this

     6-14
     
     


MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


factor needs to be recognized as beyond the direct control of MTC.

Joint use agreements with the military

    Civil use of military airport facilities will require the
development and/or enhancement of joint use agreements with the
appropriate military sponsors and/or participation in the FAA's
Military Airports Program (MAP).  As an "ample, until mid 1992
Travis Air Force Base had a civil/military joint-use agreement which
allowed up to 12 daily operations with civil aircraft.  As of May
1992, however, that joint use agreement expired.  In order to
develop Travis as a significant passenger service facility a new
agreement would have to be drafted and approved.  In addition, that
joint use agreement would need to allow significantly more daily
flights than the former agreement (which allowed 12 flights per
day).  As a result of the series of military base closures across
the nation in recent months, Travis has had its mission increased,
with levels of activity increased accordingly.  In the short term
this would make reinstating a joint use agreement more difficult.

Public transportation improvements to airports

     As mentioned above in relation to ground access, airport
expansion and growth in passenger and cargo traffic will put
additional pressure on the region's surface transportation system. 
Airport expansion plans must also consider the need for public
transportation system improvements to serve the airport.  Specific
examples which are already recognized and under study are a BART
extension to SFO, a future BART connection to OAK, and a future
connection between SJC and the Santa Clara County light rail line.

Funding

     Nearly all elements of every alternative will have some cost.  
This applies to airport improvements, airspace changes, airline
actions, ground access improvements, and public transportation
projects.  The funding implications of specific elements relate to
the overall cost and the timing and availability of funds.

Impacts on general aviation

     A number of actions at the five air carrier airports would
depend on significant diversion of general aviation at those
airports to enhance capacity for future growth in air carrier
activity.  Significant expansion of passenger and cargo activities
will likely increase the need for GA activities to relocate.






     6-15
     
     


MTC Regional Airport System Plan Update
Chapter 6: Airport System Alternatives Definition   September 9, 1994


Operating Agencies

     Where joint use facilities or new airports are proposed,
operating agencies would need to be designated or established.

Potential markets Practical application

     This applies primarily to the use of new technology.  The
effectiveness of new technology to address the region's air travel
demand will be affected by the potential market for and the degree
and timing of practical application of such technology.  For
example, the effective use of high speed rail within the California
corridor as an alternative to air travel will be constrained by such
factors as:

   1.   The portion of the total market which can be diverted from
        air to rail.

   2.   The degree and timing of actual application of the
        technology.
   3.   The relative cost, comfort, speed, and safety of rail travel
        as opposed to air travel.

Noise/land use comparability/encroachment protection

     A critical issue in evaluating alternatives for the region will
be how well noise and land use compatibility can be achieved or
maintained.  It may be possible to accommodate significant increases
in demand at a particular airport, but only at great expense in
terms of impacts to adjoining communities.  Thus there will be clear
trade-offs between efficiently meeting future demand and minimizing
human impacts.

     A related issue is that of encroachment.  If public funds are
to be effectively invested in airport facilities, the public must
provide for the protection of that public investment from
encroachment by non compatible land uses.  Both the noise and
encroachment issues can be addressed in part by height hazard and
safety planning and zoning.

7       AIR CARRIER AIRPORT SYSTEM ALTERNATIVES  EVALUATION

     This chapter contains a brief summary of the air carrier
alternatives evaluation, a more detailed description of the
alternatives evaluation methodology, and a discussion of the
evaluation results.

7.1     SUMMARY OF ALTERNATIVES EVALUATION

7.1.1   Evaluation Summary for Air Carrier Airports

Summary of Evaluation Process and Results

     The alternatives evaluation process contained three basic
steps: (1) a set of criteria by which to evaluate and compare the
alternatives was developed; (2) a computer model (spreadsheet) to
organize data and help with the evaluation was developed; and (3)
the results of the evaluation were reported.  These steps are
discussed in detail in the full text of this chapter, and summarized
below.

Evaluation Criteria

     Evaluation criteria were developed by the project team and
reviewed, refined, and approved by the RAPC.  These criteria were
then used as the basis for developing the evaluation model.  The
criteria were as follows:

1.      Airside (runway) capacity and delay
     
2.      Landside capacity:  Passenger capacity and gate requirements
                            Air cargo
                            Based aircraft
3.      Parking capacity
4.      Airport access/distribution of supply and demand
5.      Air quality
6.      Noise impacts
7.      Wildlife/wetland/bay fill
8.      Construction cost and impacts
9.      Economic benefit
10.     MTC implementation options
11.     Land acquisition requirements

Evaluation Approach

     In order to organize the information to be used in the
evaluation process, a spreadsheet approach was developed.  In
addition, some input was developed by using MTC's Airport "ACCESS"
model to evaluate airport use based on ground access times and
flight availability.  Each evaluation form lists how the alternative
performs relative to Specific evaluation factors.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


Evaluation Results

The following is a brief summary of the evaluation results for each
alternative in the  year  2010.

No Build Alternative

The No Build alternative would result in the following:

   1.   Current market shares would continue, with SFO dominating the
        region.
   2.   Operations demand would exceed annual  runway  capacity  at 
        San  Francisco  and  San  Jose. At San Jose operations demand
        would exceed  capacity  primarily  due  to  the  large 
        amount of GA activity which is forecast.
   3.   Oakland, Concord, and Sonoma County would have excess runway
        capacity.
   4.   Peak hour demand would far exceed  capacity  in  Instrument 
        Flight  Rule  (IFR)  conditions at  all  airports  except 
        Sonoma  County.  With  the  exception  of   Concord   (CCR)  
        and Sonoma  County  (STS),  delay  during  IFR  conditions 
        would   be   unacceptable   at   all airports.
   5.   Peak hour demand in Visual Flight  Rule  (VFR)  conditions 
        would  far  exceed  capacity  at SFO, while OAK and SJC 
        would  be  at  capacity.  Resulting  delays  would  be 
        marginal  at OAK  and  SJC  and  would  reach  unacceptable 
        levels  at  SFO.  CCR  and  STS  would  have excess capacity.
   6.   With no new capacity being added,  SFO,  OAK,  and  SJC 
        would  fall  far  short  of  annual passenger  demand  by 
        the  year  2010.  Annual  demand  would  exceed  passenger  
        terminal capacity by 17 million to 32 million passengers,
        with  a  total  deficiency  of  between  55 and 80 gates.
        Most of this deficiency  would  be  at  SFO.  Resulting 
        delay  and  passenger inconvenience would be significant.
   7.   At San Jose general aviation based aircraft demand would
        exceed capacity.
   8.   Existing space for air cargo activity would  not  meet 
        forecast  demand  at  SFO,  OAK,  or sic.
   9.   Vehicle parking demand would significantly outstrip supply at
        all    airports.
   10.  With  regional  market  shares  unchanged,  the  No   Build  
        alternative   would   generate significant levels of daily
        vehicle miles travelled Oust over 4 million), total daily 
        trips (168,000), and trips on the region's bridges (almost 
        38,000),  with  resulting  impacts  on regional air quality
        due to vehicle emissions. This  alternative  would  create 
        the  second highest level of vehicular traffic of all the 
        alternatives,  and  would  likely  result  in significant
        landside congestion and delay.
   11.  No significant construction, wildlife, wetland, or fill
        impacts are associated with  the  No Build alternative, since
        no major construction would be undertaken.

Airport System Management (ASM Alternative

The System Management alternative would result in the following:

   1.   Current market shares would shift, with slight increases  at 
        OAK  and  SJC,  and  a  decrease at SFO (from 70.7 percent to
        64.5 percent).
   2.   Improvements  in  the  system's  capacity  will  occur 
        through  management   methods   rather than construction of
        facilities.
   3.   Annual  operations  demand  would  exceed  annual  runway 
        capacity  only  at  San  Jose.   If San Jose's GA activity
        could  be  reduced  by  21  percent  the  airfield  could 
        meet  annual demand in the year 2010.
   4.   San  Francisco,  Oakland,  Concord,  and  Sonoma  County 
        would  each   have   excess   annual runway capacity.
   5.   Peak  hour  demand  would  far  exceed  capacity  in  IFR 
        conditions  at   all   but   Sonoma County. Except at CCR and
        STS, peak hour IFR delay would be unacceptable.
   6.   Peak hour demand  in  VFR  conditions  would  far  exceed 
        capacity  at  SFO,  while  OAK  and SJC would be near or  at 
        capacity.  Resulting  delays  would  be  marginal  at  OAK 
        and  SJC and, unacceptable at  SFO.  CCR  and  STS  would 
        have  acceptable  levels  of  delay  in  VFR conditions.
   7.   Annual  passenger  capacity  Landside)  at  SFO,  OAK,  and 
        SJC  would  fall  far  short   of annual passenger  demand 
        by  the  year  2010,  with  SFO  having  the  largest 
        deficit.  CCR and  STS  could  accommodate  forecast 
        passenger  demand.  Total   regional   annual   demand would
        exceed  total  regional  passenger  terminal  capacity  by 
        12  million  to  27  million passengers, with a total
        deficiency of  between  46  and  63  gates.  With  SFO 
        serving  64.5 percent of the region's total passenger demand,
        most of  this  deficiency  would  be  at  SFO.
   8.   At San Jose, general aviation based aircraft demand would
        exceed capacity.
   9.   With air cargo processing space fixed at current levels and
        demand continuing  to  grow, existing space for air cargo 
        activity  would  not  meet  forecast  demand  at  SFO,  OAK, 
        or sic.
   10.  Vehicle parking  demand  would  significantly  outstrip 
        supply  at  all  airports,  with  the region facing a total
        deficit of nearly 30,000 spaces.
   11.  With the regional  shift  in  market  shares,  the  ASM 
        alternative  would  move  the  region toward a more efficient
        distribution of  supply  and  demand,  and  would  therefore 
        generate lower levels of daily vehicle miles travelled (3.8
        million), total daily trips (166,000),  and trips on the
        region's bridges (31,000),  when  compared  to  the  No 
        Build  alternative.  The ASM alternative would therefore
        result in reduced impacts  on  regional  air  quality  due 
        to vehicle  emissions.  The  ASM  alternative  would 
        generate  about  7  percent  less   vehicle miles and daily
        trips than the No Build option.
   12.  No significant construction, wildlife, wetland,  or  fill 
        impacts  are  associated  with  the 'Airport System
        Management alternative.

Master Plans Alternative

Selection of the Master Plans alternative would result in the
following:

   1.   Current  market  shares  would  shift  even  more  than  with 
        the  ASM   option,   with   SFO's share of the  regional 
        passenger  market  dropping  from  70.7  percent  (No  Build) 
        and  64.5 percent (ASM) to 61.5 percent for the Master Plans.
   2.   Annual  airfield  operations  capacity  would  accommodate 
        forecast  demand  at  all   airports except San Jose, again
        due to the high level of GA demand at SJC.
   3.   Oakland, Concord, and Sonoma County would have excess annual
        runway capacity.
   4.   Peak  hour  demand  would  exceed  capacity  in  EAR 
        conditions  at  all  but  Sonoma   County. Except at CCR and
        STS, peak hour IFR delay would be unacceptable.
   5.    Peak  hour  demand  in  VFR  conditions  would  exceed  
        capacity   at   SFO,   OAK   and   SJC. Resulting  delays 
        would  be  unacceptable  at  all  three   airports.   CCR  
        and   STS   would experience acceptable delay in VFR
        conditions.
   6.    Landside facilities  at  SFO,  OAK,  SJC,  CCR,  and  STS 
        would  all  be  able  to  accommodate the forecast level of
        annual passengers.
   7.    At San Jose general aviation based aircraft demand would
        exceed capacity.
   8.   Existing  and  planned  space  for  air  cargo  activity
        would  meet  forecast  demand  at  SFO OAK, and SJC.
   9.   Vehicle  parking  capacity  would  meet  anticipated  demand 
        at   SFO   and   OAK   and   would fall slightly short  of 
        demand  (10  percent)  at  SJC.  CCR  and  STS  would  need 
        additional vehicle parking to meet demand, according to
        current master plan documents.
   10.  With the shifts in regional market shares anticipated in  the 
        Master  Plans,  this  alternative would generate fewer
        vehicle miles travelled, total daily  trips,  and  trips  on 
        the  region's bridges  to  SFO,  but  slightly  more  to  OAK 
        and  SJC  (and  in  the  total  region),   when compared  to 
        the  No  Build  alternative.  Total  vehicle  emissions  
        generated   by   surface traffic would be similar to that of 
        the  No  Build.  The  Master  Plans  alternative  generates
        the highest level of surface traffic of all the alternatives,
        due in part to the  fact  that  it would  accommodate  more 
        total  annual  passenger  traffic  (89,454,000)  than   the  
        forecast level for the other alternatives (84,763,333).  Were 
        this  difference  in  level  of  passenger traffic equalized, 
        the  Master  Plans  would  generate  a  level  of  surface 
        vehicle  traffic estimated to be slightly lower than the No
        Build alternative.
   11.  Significant  construction  activity  would  occur  at  SFO, 
        OAK,  and  SJC  in  order  to  meet anticipated  demand. 
        This  would  include  major  projects  to  expand   passenger 
         terminals, vehicle parking, air cargo facilities, general
        aviation facilities, airport and airline  support facilities, 
        and  major  surface  access  improvements  (including 
        proposed  BART   connections to SFO and OAK).
   12.  No significant wildlife, wetland, or fill impacts are
        anticipated with this alternative.

Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


System Optimization "A" Alternative

The System Optimization "A" alternative would result in the
following:

   1.   Current regional market shares would  shift  markedly  (SFO 
        would  drop  from  its  current 70.0  percent  to  50.3 
        percent),  and  most  new  growth  and  airport  development 
        would occur at OAK and SJC.
   2.   Annual airfield operations capacity would meet  projected 
        demand  at  all  airports  except SJC,  which  would  still 
        not  be  able  to  accommodate  all  forecast  General  
        Aviation demand.
   3.   San  Francisco,  Oakland,  Concord,  and  Sonoma  County 
        would  all  have   excess   annual runway capacity through
        the year 2010.
   4.   Peak  hour  demand  would  far  exceed  capacity  in  IFR 
        conditions  at  all  but   Sonoma County. Except at CCR and
        STS, peak hour EAR delay would be unacceptable.
   5.   Peak  hour  demand  in  VFR  conditions  would  also  exceed 
        capacity  at  SFO,  OAK,   and SJC. Resulting  delays  would 
        be  marginal  to  unacceptable  at  SFO,  OAK  and  SJC.  CCR
        and STS would have excess capacity, and peak hour delays
        would not be significant.
   6.   AR five air carrier airports would be able to  accommodate 
        all  forecast  passenger  demand through the year 2010. This
        includes all  major  passenger  processing  facilities  such 
        as passenger terminal, parking, aircraft gates, and surface
        access facilities.
   7.   At San Jose, general aviation based aircraft demand would
        exceed capacity.
   8.   Because of the amount of passenger growth at  Oakland  and 
        San  Jose,  the  existing  space for air cargo  activity  at 
        these  two  airports  may  not  meet  forecast  demand 
        without conversion of existing general aviation space to air
        cargo.
   9.   Vehicle parking capacity would meet demand at all airports
        except Concord.
   10.  Regional market shares would be significantly altered  under 
        the  System  Optimization  'A' alternative, with the major
        impact being a more equitable regional  distribution  of 
        supply and demand than currently exists. This option produces
        the  second  lowest  level  of  total daily vehicle miles
        travelled (3.7 million), total daily trips (162,000), and
        daily  vehicle trips on bay bridges (28,401). This translates
        to about 13 percent less traffic impact  than the No Build,
        and to a similar lower level of potential air quality impact
        as well.
   11.  In addition to the terminal building, vehicle parking, air
        cargo, airport  support,  general aviation, and surface 
        access  construction  projects  that  would  occur  with  the 
        System Optimization "A" alternative, this option also
        includes construction of a new, parallel  air carrier runway 
        at  Oakland.  Depending  on  which  runway  alignment  is 
        assumed  (inboard or outboard), as well as the spacing 
        between  the  existing  and  new  runway  (750-800  or 2,500
        feet), there would likely be wildlife impacts, as well as 
        the  potential  filling  of between 124 and 135 acres of
        freshwater wetland, and up to 57 acres of Bay fill.

Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


System Optimization "B" Alternative

The System Optimization 'B" alternative would result in the
following:

   1.   As  with  the  System  Optimization  'A'  alternative 
        (described  above),  option  'B'  would significantly  depart 
        from  current  market  shares,  with  most  new  growth   and 
         airport development occurring at OAK, SJC, and a new air
        carrier airport at Travis AFB.
   2.   Annual airfield operations capacity  would  meet  projected 
        demand  at  all  airports  except SJC, which would still not
        be able to accommodate all General Aviation demand.
   3.   San  Francisco,  Oakland,  Concord,  and  Sonoma  County 
        would   all   have   excess   annual runway capacity through
        the year 2010.
   4.   Peak hour demand  would  far  exceed  capacity  in  EAR 
        conditions  at  all  but  Travis  and Sonoma County. At  all 
        the  other  airports  peak  hour  IFR  delay  would  be 
        unacceptable.
   5.   Peak  hour  demand  in  VFR  conditions  would  also  exceed 
        capacity  at   SFO,   OAK,   and SJC.  Resulting  delays 
        would  be  marginal  to   unacceptable   at   SFO,   OAK  
        and   SJC. Travis,  CCR,  and  STS  would  have  excess 
        capacity,  and  peak  hour   delays   would   be
        insignificant.
   6.   Four of the six air carrier airports would be  able  to 
        accommodate  all  forecast  passenger demand through the 
        year  2010.  This  includes  all  major  passenger 
        processing  facilities such as passenger terminal, parking, 
        aircraft  gates,  and  surface  access  facilities.  At
        Oakland and San Jose, however, annual passenger demand would
        exceed capacity.
   7.   At San Jose, general aviation based aircraft demand would
        exceed capacity.
   8.   Because of the amount of new  passenger  activity  at 
        Oakland  and  San  Jose,  the  existing space for air cargo
        activity at these two  airports  may  not  meet  forecast 
        demand  without conversion of existing general aviation space
        to air cargo.
   9.   Vehicle parking capacity would  meet  demand  at  all 
        airports  except  Concord,  where  some 400 additional spaces
        are needed.
   10.  Regional market shares would be  significantly  altered 
        under  the  System  Optimization  'A' alternative, with the
        major impact being a more  equitable  regional  distribution 
        of  supply and demand than currently exists. This  option 
        produces  the  lowest  level  of  total  daily vehicle miles
        travelled of all the alternatives (3.48 million), the second
        lowest total  daily trips (163,282), and by far the lowest
        level of daily vehicle trips on bay  bridges  (21,221). These
        numbers represent some  13  percent  less  traffic  impact 
        than  the  No  Build,  which translates to a similarly lower
        level of potential air quality impact as well.

   11.  In addition to the terminal building, vehicle parking, air
        cargo, airport  support,  general aviation, and surface 
        access  construction  projects  that  would  occur  with  the 
        System Optimization "A" alternative, this option also
        includes construction of a new, parallel  air carrier  runway 
        at  Oakland.  Depending  on  which  runway  alignment  is  
        assumed,   this could create wildlife impacts, as well as the
        potential  filling  of  between  124  and  135 acres of
        freshwater wetland, and up to 57 acres of Bay  fill  for  a 
        750-800  foot  closely spaced runway parallel to 11-29, and
        would entail either 387 acres of Bay fill or  68  acres of
        freshwater wetland for  a  new  parallel  runway  with  2,500 
        feet  of  separation  from runway  11-29.  This  alternative 
        would  also  include  major  capacity   improvements   at
        Travis, including expansion of the  passenger  terminal, 
        expanded  vehicle  parking,  apron expansion, new airline
        support facilities, and improvements to  the  surface  access 
        system serving the airport.

New Technologies Alternative

The New Technologies alternative would result in the following:

   1.   Current market shares would continue,  with  SFO  dominating 
        the  region.  Traffic  volumes at the five existing air
        carrier airports  would  only  be  reduced  by  the  amount 
        of traffic which could be diverted to a new high-speed rail
        system, non-airport  vertiports,  or  both.
   2.   Operations demand would exceed annual  runway  capacity  at 
        San  Francisco  and  San  Jose. At San Jose, operations
        demand would exceed capacity  primarily  due  to  the  large 
        amount of GA activity which is forecast.
   3.   Oakland, Concord, and Sonoma County would have excess annual
        runway capacity.
   4.   Peak  hour  demand  would  far  exceed  capacity  in  IFR 
        conditions  at  all  but   Sonoma County. Except at CCR and
        STS, peak hour IFR delay would be unacceptable.
   5.   Peak hour demand in VFR  conditions  would  far  exceed 
        capacity  at  SFO,  while  OAK  and SJC would  be  at 
        capacity.  Resulting  delays  would  be  marginal  at  OAK 
        and  SJC  and unacceptable  at  SFO.  CCR  and  STS  would 
        have   excess   capacity,   and   would   have acceptable
        levels of peak hour delay.
   6.   SFO would fall far short of annual passenger demand  by  the 
        year  2010,  while  the  other four  airports  would 
        accommodate  forecast  annual  passenger   demand.   Total  
        regional annual demand would exceed  passenger  terminal 
        capacity  by  5  million  passengers  under the high
        forecast, with the total number gates sufficient to meet
        regional demand.
   7.   At San Jose, general aviation  based  aircraft  demand  would 
        exceed  capacity.
   8.   Existing space for air cargo activity would  meet  forecast 
        demand  at  SFO  and  OAK,  but would be insufficient at SJC.
   9.   With no major  new  parking  facilities  being  added,  this 
        alternative  would  experience vehicle parking  demand
        significantly greater than supply at all airports.




     7-7
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


   10.  With  regional  market  shares   unchanged,   the   New  
        Technologies   alternative   would generate significant
        levels of vehicle miles travelled, total daily trips, and
        trips on  the region's bridges, with resulting impacts on
        regional air quality due to  vehicle  emissions. These
        traffic levels would be similar to, though slightly lower (2 
        percent),  than  the  No Build alternative.
   11.  No significant construction, wildlife, wetland, or fill
        impacts are associated with the  New Technologies alternative
        as it relates  to  increasing  airport  capacity.  The 
        alternative would, however, generate significant impacts 
        related  to  the  construction  and  operation of  the  new 
        high-speed  rail  system  connecting  central  and  southern 
        California.   Of primary  importance  would  be  impacts 
        related  to  right-of-way  acquisition  and  actual
        construction of the rail route.

7.2     AIR CARRIER ALTERNATIVES EVALUATION

The evaluation of air carrier alternatives was a three-step process:

        Step  1:  Establish a set of evaluation criteria
        Step  2:  Develop a methodology for evaluating the
                  alternatives using those criteria
        Step  3:  Complete the evaluation and report the results


7.2.1   Evaluation Criteria

   1.   Airside (Runway) Capacity and Delay

   Alternatives were evaluated by comparing airspace and airside
(runway) capacity with forecast demand by airport and for the entire
system.  The following measures were used:

   *    Annual operations capacity (Annual Service Volume) 
   *    Peak hour capacity (VFR and IFR)

     Delay for each air carrier airport was evaluated using  the 
following  methodology:

Total annual delay

     Total annual delay was determined by comparing the forecast
number of total annual operations with the total annual capacity
(defined as annual service volume) of each airport.  Where the level
of demand was less than 80 percent of capacity the alternative was
rated as 'acceptable'.  Where demand was between 80 and 100 percent
of capacity, the rating was "marginal".  If demand exceeded capacity
the alternative was rated as 'unacceptable'.

Peak hour delay

     Peak hour delay was determined by comparing the forecast peak
hour demand with peak hour capacity under both VFR and IFR
conditions.  Where demand was less than 90 percent of capacity, the
alternative was rated as 'acceptable'.  Where demand was between 90
and 110 percent of capacity, the rating was "marginal".  If demand
exceeded 110 percent of capacity the rating was "unacceptable". 
These peak hour delay measures ("acceptable," "marginal," and
"unacceptable') were generally based upon the following definitions:

   "Acceptable":       Average aircraft delay of less than 4 minutes
   "Marginal":         Average aircraft delay between 4 and 10
                       minutes
   "Unacceptable":     Average aircraft delay more than 10 minutes


     7-9
     



MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


          The 4-minute average delay is the traditional threshold of
acceptable delay used by the FAA in airport planning.  Delays of
more than 10 minutes per aircraft represent conditions of system
breakdown, with serious congestion and passenger inconvenience.  The
10-minute level has been set here to represent the point where delay
becomes 'unacceptable'.

     Unlike total annual delay as described above, peak hour delay
was considered acceptable at higher demand-to-capacity ratios.  This
is because peak hour traffic which exceeds capacity can (and will)
be shifted into adjoining hours of the day, whereas demand which
exceeds annual capacity cannot be shifted into an adjoining year. 
Although shifting peak hour demand to adjoining hours (sometimes
called 'spreading the peak') can provide some help in overcoming
airport parking, it is limited by a number of factors.  These
include the level of demand occurring during those adjoining hours,
passenger convenience, the willingness of airlines to operate under
these conditions, and others.  Diversion of general aviation
activity can also reduce peak hour delays.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     Peak hour and total annual passenger capacity was compared with
peak hour and total annual demand.  Terminal and support facility
capacity was measured using a number of factors, including:

   *    Number of gates
   *    Total terminal size / available land area 
   *    Terminal curb frontage
   *    Level of service
   *    Other measures

Air Cargo

     The alternatives were qualitatively evaluated as to how well
forecast air cargo demand is accommodated.  Additionally, they were
evaluated as to their impact on existing air cargo operations and
facilities.

General Aviation Based Aircraft

     GA based aircraft demand was reviewed and compared to based
aircraft capacity using the following measures:

   *    Aircraft tie-downs
   *    Itinerant apron

     7-10
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


   *    Hangar space
   *    Total based aircraft

3.      Auto Parking Capacity

     Parking demand and capacity were evaluated for each airport
under each alternative.  Both on-airport and off-airport parking was
included.

4.      Airport Access/Distribution of Supply and Demand

     Each alternative was evaluated as to the level of vehicular
traffic that would be generated by passenger activity.  This
analysis, which included total daily vehicle trips and total daily
vehicle miles travelled to each airport, was derived from the MTC
'ACCESS' model.  These data were then used for the air quality
analysis.

     In addition, the alternatives were evaluated based on airport
access and how well airports would be served by (or could be served
by) the region's surface and public transportation system. The
"ACCESS" model was run to determine how much regional airport access
traffic could be diverted from private vehicles to transit if BART
connections were constructed to San Francisco and Oakland.

 5.     Air Quality

     Air quality will be affected by the amount of vehicular traffic
to and from the airports, traffic speeds on roadways serving the
airports, traffic volumes and speeds for vehicles operating on the
airport (terminal curbs and roadways), delays experienced by
aircraft on the airfield, and the total volume and peaking
characteristics of aircraft operations.

     Under this criterion each alternative was assessed based on the
total amount of air pollution produced (hydrocarbons and carbon
monoxide).  Total air pollution was determined by the following:

   *    Total number of aircraft operations and fleet mix
   *    Total number of vehicle trips
   *    Total miles travelled, average speed, and vehicle emissions
        factors
   *    Total air quality impact (aircraft and surface vehicles)

6.      Noise Impacts

     This criterion established the relative noise impact for each
alternative based on the total area within the noise contours
(acres/square miles) and the amount of noise-sensitive land use
within the contour.  The ability to identify land uses within the
noise contours was based on existing

Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


published information supplied by the five air carrier airports. 
Where this information was not available the noise impact analysis
simply compared the total area within the noise contour for each
alternative.

7.      Wildlife/Wetland/Bay Fill

     Total amount of wildlife, wetland fill, and bay fill (measured
in acres) associated with each alternative was determined based on
existing data in master plans, EIS documents, etc.

8.      Construction Cost and Impacts

     This criterion determined the generalized construction cost and
impacts for each alternative and compared the alternatives.

9.      Economic Benefit

     Existing published information and other sources were used to
develop generalized comparative estimates of total aggregate
economic benefits for each alternative.  The following four basic
areas of economic benefit were included:

   *    Total economic benefit derived from airport construction
        (taxes, employment, etc.)
   *    Economic benefit derived from operations Landing fees, etc.)
   *    Economic benefit derived from passengers (tourist spending,
        etc.)
   *    Economic benefit derived from overall airport activity
        (multiplier effect)

     Existing economic benefit data for the air carrier airports in
the region and the state, and data from other sources were reviewed.

10.     Implementation

     One of the elements of the evaluation process were the options
to implement the alternatives, such as funding and environmental
approval, as well as time frame for implementation.  These options
were identified and qualitatively compared.

11.     Land Acquisition Requirements

     Alternatives were evaluated as to the amount of land
acquisition required to implement them.  This primarily applied to
major expansions at existing airports and new airport alternatives.

Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


7.2.2  Evaluation Methodology

     The evaluation process generated a series of spreadsheet
tables, which collectively display the six air carrier system
alternatives, two forecasts for each (high and low), and five time
frames (1990, 1995, 2000, 2005, 2010).  Future airside and landside
demand and capacity, along with resultant delay and environmental
impacts, were determined from the passenger forecast numbers.

     A number of assumptions and factors underlie the calculations
of airport activity and impacts.  The major ones are passenger
market shares; originating and destination (O & D), connecting, and
international passenger splits (percentages); aircraft size;
aircraft load factors; airport operational parking factors; and gate
requirements.  These are listed below, and are displayed in tables
which accompany the text.

Passenger Market Share

     "Passenger market share" refers to the relative percentage of
the total regional passenger traffic served at each airport .  In
1990 San Francisco served about 71 percent of the total passengers
in the region (30 million out of a regional total of 42 million),
Oakland's market share was 13 percent, San Jose's was just under 16
percent.  Concord and Sonoma County each had less than .5 percent.

     The inventory and forecast chapters of this report discuss the
historic and current market shares of the five existing air carrier
airports in the region.  After analyzing the historic and current
market shares, reviewing the results of the 1990 MTC Air Passenger
Survey, and studying the recommendations of other airport planning
studies and reports, a key issue emerged which needed to be
addressed in this system planning effort: Does the existing   
airport      system offer an efficient and convenient system of
airport facilities (supply) relative to the regional origins and
destinations of passengers (demand), and considering their mode of
travel to and from the airports.

     In order to evaluate a number of market share alternatives,
passenger market shares have been distributed differently for each
alternative.  This allowed the evaluation of how the entire air
carrier airport system would perform given a series of differing
assumptions about regional market shares.  The passenger market
shares for each alternative were developed using the "ACCESS" model,
which was developed by MTC.  These shares are displayed in Exhibit
7.1.

     The "ACCESS" model generated four basic passenger market share
scenarios:

   (1)     Existing 1990 shares -- This scenario allocates future
   passenger traffic to the five air carrier airports based on 1990
   market shares.  This allocation method was used for the No Build
   and New Technology alternatives.

     7-13

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


   (2)     Equilibrated shares -- This scenario allocates passengers
   to the region's airports according to an airport choice model,
   with flight frequency at OAK and SJC set to levels which are
   sustainable by demand at those airports.  This allocation method
   was used for the Airport System Management alternative.

   (3)     Master Plan shares -- The existing airport master plans
   are constructed around the concept of regional market shares.  The
   regional market shares contained in the master plans were used for
   the Master Plan alternative.  These include both unconstrained and
   constrained forecasts, each resulting in different passenger
   market shares.

   (4)     Maximum shares -- The scenario allocates passengers to the
   region's airports based on the airport choice model (passengers
   will choose the airport which is the most convenient, as measured
   by travel time to and from the airport).  In this scenario, flight
   frequencies to all destinations from all three airports were set
   at maximum levels, thus equalizing the three airports in terms of
   levels of service.  This allocation method was used for the
   Optimization alternatives "A" and "B".

Passenger Splits

     The passenger percentages (splits) at each airport were
developed by dividing total passenger traffic into three categories:
(1) passengers having a domestic origin or destination at an airport
("O&D" passengers); (2) passengers connecting between air carrier
flights at a hub airport ("connecting" passengers); and (3)
passengers with international origins or destinations
("international" passengers).  Of the International passengers, some
are 'O&D' and some are "connecting".  These splits are shown in
Exhibit 7.2 for the years 1990 and 2010.  With the exception of San
Francisco, which will see a slight rise in the percentage of
international passengers, all passenger splits are expected to
remain relatively stable between 1990 and 2010.

     The relative number of each type of passenger is important in
planning for airside capacity as well as passenger terminal and
other landside facilities, such as surface access and parking.  For
example, an airport having high levels of O&D traffic would require
more auto parking, ticketing, and baggage claim facilities, whereas
an airport with high levels of connecting passengers would not need
these facilities, but would still require airside capacity which
could be devoted to regional O&D traffic.

     International passengers, in contrast, require specialized
processing facilities, such as increased levels of passenger and
baggage security, immigration, customs, and other Federal Inspection
Services.  Because of the cost to build and operate these special
facilities, there has been some discussion concerning centralizing
these functions at one airport.  This would be efficient and reduce
duplication, but would not be as convenient to the region's
passengers.  Centralization of the region's international passenger
handling facilities would therefore have both positive and negative
attributes.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


Changes in Aircraft Size and Load Factor

     Two of the most important factors which were evaluated in the
alternatives analysis were future changes in aircraft size and load
factors.  The combination of these two factors yields the number of
passengers per operation, which is discussed below.  Aircraft size
and load factor have the potential for contributing major increases
in worldwide air service capacity in the coming 20 years.  The San
Francisco International Airport Master Plan Update, for example,
anticipates that the existing airfield can accommodate an increase
from 30 million annual passengers in 1990 to over 53 million annual
passengers in 2006 without any major runway capacity enhancement
projects.  Rather, the plan is built around several major landside
and terminal capacity improvements and the basic assumptions that
average aircraft size and load factors will increase significantly
at SFO in the future.

     Indeed, all the alternatives evaluated in this system plan take
into consideration some basic worldwide and national trends in
aircraft size and load factors, using information about existing and
forecast conditions at the region's airports as well as FAA and
industry forecasts.

     Boeing, McDonnell Douglas, and the FAA have each prepared
forecasts for average aircraft size and load factors.  Both aircraft
manufacturers have aircraft seating size projections for the world
market.  These numbers tend to be higher than domestic figures
because of the heavy use of large, wide-body aircraft on
international, transoceanic routes.  In order to predict these
factors for the domestic fleet, an analysis of future fleet mix for
the ten major US airlines currently serving the Bay Area was
prepared.  These airlines were United, American, Delta, USAir,
Southwest, Alaska, TWA, Continental, America West, and Northwest. 
Domestic load factor forecasts for 2000 were derived from the FAA,
and forecasts for the year 2010 were derived from industry sources
and the individual airport master plans.

     Based on these data, aircraft size and load factors for SFO are
expected to remain greater than corresponding figures for OAK and
SJC, while figures for CCR and STS will be consistent with their
continued role as general aviation airports, with limited commuter
airline service.  The aircraft sizes used in the analysis are
smaller than those in the Boeing and McDonnell Douglas worldwide
figures, reflecting the fact that a large share of the Oakland
market is serving the California corridor, and that San Jose serves
primarily the domestic U.S. market.  San Francisco maintains higher
load factors and is served by larger aircraft, consistent with its
role as a domestic and international hub as well as with its sheer
size.

     Trends in aircraft size and load factor are illustrated in
Exhibit 7.3. As shown in the exhibit, San Francisco, Oakland, and
San Jose will see increases in both aircraft size and load factors
in the future.  These increases are expected to occur under all the
alternatives, including the No Build.  This reflects the expectation
that the Bay Area airports will reap the benefits of worldwide and
national trends regardless of local or regional decisions regarding
development of the airport system.  Under the Airport System
Management alternative, however, the aircraft

     7-15
     
     


Click HERE for graphic.





MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


size and load factors have been increased more than under the other
alternatives.  This reflects the attempt to maximize airport system
capacity with the ASM alternative using operational and management
measures by airports and airlines without major construction.

Passengers Per Operation

     The concept of "passengers per operation" is not normally used
in airport planning.  Instead, the individual measures of aircraft
size (fleet mix) and load factor are used.  These factors were
combined here (see Exhibit 7.4) only to simplify the calculations
used in the evaluation model.  The number of passengers per
operation is a direct product of aircraft size and load factor, as
discussed above.  Passengers per operation for 1990, 1995, 2000,
2005, and 2010 are shown for each alternative in Exhibit 7.4. For
the No Build, Optimization 'A' and 'B', and New Technology
alternatives, the number of passengers per operation is expected to
grow from 95 to 120 at SFO, from 65 to 90 at OAK, and from 47 to 90
at SJC.  Under the ASM alternative, these 2010 figures increase to
130, 100, and 100, respectively.  For the Master Plans option the
2010 figures are 105 for SFO, 78 for OAK, and 68 for SJC.  Under the
System Optimization "B" alternative Travis is assumed to serve 90
passengers per operation, the same figure used for Oakland and San
Jose.

     Using the total passenger traffic forecast and the passengers
per operation figures, the evaluation model calculates the
anticipated number of annual air carrier operations required to meet
annual forecast passenger demand.  Annual operations demand figures
were then converted into peak hour operations demand for both VFR
and EAR conditions as discussed below.

     While most major airlines have current orders for a large
number of small jet aircraft (Boeing 737 and Fokker-100-size), the
ultimate trend is likely to be toward larger aircraft.  This is
particularly true for international flights, but it will also be
true for domestic service.  The development of the 757, 767, 777,
MD-11, MD-12, and larger Airbus models (A-300, A-330, and A-340)
reflects the aircraft industry's view that larger aircraft will be
among the capacity enhancements needed to meet projected demand.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


Peak Hour Operations as a Percentage of Total Annual Operations

     In each of the master plans for the three largest air carrier
airports, an analysis and forecast of peak hour operations was
performed.  The peak hour operations are determined by establishing
the peak month, the average day in the peak month, then the peak
hour of the average day.  These figures, which are displayed in
Exhibit 7.5, were derived as follows:

        Step  1:  Begin with total annual operations (derived from 
                  total  annual  passenger  forecast divided by
                  passengers per operation)

        Step  2:  Calculate peak month operations as a percentage of
                  total  annual  operations  (e.g., 11  percent)

        Step  3:  Calculate average day operations as a percentage of 
                  peak  month  operations  (e.g., 3 percent)

        Step  4:  Calculate peak hour operations as a percentage  of 
                  average  day  operations  (e.g., 10  percent)

     Forecasts of peak hour operations used in this analysis     
are based on a single multiplier which establishes peak hour
operations as a percentage of the total annual operations.  In the
examples given in the four steps above, the single percentage figure
would be:

   Peak hour ops  = Total annual ops x .11 x .03 x .10 
                  = .00033

     The figures in Exhibit 7.5 are the result of applying the above
process (using the individual parking characteristics for each
airport) to the annual operations numbers for each airport.  These
factors vary by airport and by alternative.  This reflects the fact
that as an airport approaches its peak hour and annual capacity, it
will tend to have several 'peak hours', or peak periods longer than
an hour.  As demand exceeds the airport's peak hour capacity, that
demand will either be delayed or will be shifted to alternate time
periods in an attempt to level out the demand to match capacity.

     At these types of busy airports, the peak hour (or hours) will
tend to make up a decreasing proportion of the total daily traffic. 
Similarly, at smaller general aviation airports, there may not be
any major parking.  Peak hour figures as a percent of total annual
traffic may thus be similarly low for both large, congested airports
and lower-use GA facilities.  Peak hour activity as a percent of
total daily traffic will tend to be higher at airports which
experience morning and evening parking of O&D traffic or have mini-
hubs which experience two to four banks of flights during the day
but have low levels of traffic between the banks.

Gate Requirements

     Master plan forecasts of passenger levels and gate requirements
provided the data to establish a passengers-per-gate rule of thumb. 
The number of passengers per gate was used in the evaluation model
to derive the number of gates needed.  These figures, which display
only SFO, OAK, and SJC, are shown in Exhibit 7.6. As the figures
show, San Francisco is expected to process more annual passengers
per gate (494,000) than either Oakland (400,000) or San Jose
(400,000) in the year 2010.  The number of annual passengers
expected to be processed per gate combined with the total annual
passengers generates the number of gates required.

7.3    Evaluation Results

     The following results were prepared based on the input
assumptions described above. factors in the analysis include
assumptions about regional market shares, aircraft size, I factors,
and operational parking characteristics for the individual airports.

7.3.1  No Build Alternative

Exhibits 7.7 (high forecast) and 7.8 Low forecast) contain the
spreadsheet analysis for the Build alternative in the year 2010. See
Appendix A for the spreadsheet analysis for 1990, 1995 2000, and
2005.

1.      Runway Capacity and Delay

     The total system will reach annual runway capacity about the
year 2005.  SFO and SJC will above capacity by some 6 percent and 23
percent, respectively, while OAK (operating at 7 percent of
capacity), CCR (at 88 percent), and STS (at 60 percent), win have
excess annual airfield capacity.  General aviation is expected to be
a major contributor to total airfield operations demand at San Jose,
with GA comprising almost 64 percent of total airfield demand
General aviation at San Francisco and Oakland* (South Field air
carrier runway), on the other hand, will make up a relatively small
percentage of total annual operations demand (6 percent at SFO and
12 percent at OAK); however, general aviation has a disproportionate
effect capacity and delay.  At San Jose the issue of how much
general aviation activity should accommodated in light of increasing
passenger and air cargo demand is being addressed in the Airport
Master Plan Update process.  An important issue related to general
aviation in the South Bay is the future of Reid-Hillview Airport,
since discussions have occurred about the possibility of closing
this airport.  If it is closed and general aviation is reduced at
SJC there could be major shortage of facilities for general aviation
in Santa Clara County.

     Under high forecast conditions total peak hour volumes will
exceed VFR capacities at SFO 1990, OAK by 2010, and SJC by about
2012.  By the year 2010, peak hour delays an passenger inconvenience
at SFO would be significant, with VFR demand exceeding capacity b
some 63 percent.  This is due to the fact that under the No Build
alternative San Francisco would continue to serve 71 percent of the
total regional passenger demand (the same as its 1 market share). 
CCR and STS would not experience any delays during the peak hour in
VFR conditions, but CCR would experience peak hour delays during IFR
conditions.

   *    The evaluation of air carrier alternatives at Oakland are
        based only on South Field, and do not include the runways at
        North Field, which are constrained by noise issues.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


     Under the low forecast conditions, total peak hour volumes
exceed VFR peak hour runway capacity at SFO in 1990, and will reach
peak hour runway capacity at OAK in 2010, and SIC between 2005 and
2010.  The only change in the performance of the No Build
alternative between the high and low forecast is that under the low
forecast San Francisco's total annual aircraft operations demand
would fall below its annual capacity (to 89 percent), and into the
marginal delay range.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     Under the high forecast with the No Build alternative, the five
air carrier airports will reach their combined annual passenger
capacity by 1995.  OAK will reach annual passenger capacity about
the year 2001, and SIC will reach its annual capacity in 2005.

     Under both the high and low forecast SIC, CCR, and STS will
have sufficient gates to meet demand through the year 2010.  Oakland
would have nearly enough gates to meet the low forecast demand, but
would be six gates short of meeting demand under the high forecast. 
San Francisco, because it would be accepting most of the forecast
passenger growth and building no new gates, would have a serious
gate shortage by the year 2010: 41 gates short under the high
forecast and 21 gates short under the low forecast.  As a total
system the five airports will have a 50-gate shortage in meeting the
high forecast and a 20-gate shortage under the low forecast.

     Under the low forecast SFO was predicted to reach passenger
capacity in 1992, while OAK and SIC will not reach capacity until
2006 and 2010+, respectively.

Air Cargo Demand and Capacity

     If no new air cargo processing facilities are built at any of
the five air carrier airports in the next 20 years, the existing
airports will not have the capacity to handle the forecast demand
for cargo activity.  The existing air cargo facilities at SFO, OAK,
and SIC will all reach capacity by around the year 2000.  After that
time cargo demand in the region will not be met unless capacity is
added at other locations, such as Alameda NAS, Moffett Field,
Concord, Sonoma County, Travis AFB, or other airports.

General Aviation Based Aircraft

     Of the five air carrier airports, SFO and OAK can accommodate
forecast demand for based aircraft, while SIC, CCR, and STS will
fall short of meeting demand unless additional facilities are built
at these airports.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


3.      Auto Parking Capacity

     Since no additional parking would be built under this
alternative, all five airports would experience a severe shortage of
vehicle parking.  The total regional shortage in the year 2010 would
be 28,000 parking spaces under the high forecast, with demand
exceeding capacity by between 50 percent and 74 percent.  Oakland
would experience the greatest shortage in terms of the ratio of
demand to capacity (demand exceeding capacity by 74 percent, or
4,685 spaces), while San Francisco would experience the greatest
shortage in terms of absolute numbers (17,000 spaces).

     Under the low forecast regional vehicle parking demand would
exceed supply by between 33 percent and 45 percent for the three
largest airports, with total demand exceeding total supply by some
16,000 total spaces for the region.  In either case this situation
would create a serious parking problem as well as the need for
alternative forms of transport to and from all five air carrier
airports.  Proposed BART extensions to SFO and Oakland could reduce
the number of auto trips by airport passengers and thereby reduce
the need for additional parking at these two airports.

4.      Airport Access/Distribution of Supply and Demand

     Total daily vehicle miles travelled to SFO, OAK, and SJC are
shown in Exhibit 7.9, while total daily vehicle trips are displayed
in Exhibit 7.10. Total daily trips to SFO and OAK on Bay bridges
generated by each alternative are shown in Exhibit 7.11. The
greatest level of daily trips, daily vehicle miles travelled, and
traffic on Bay bridges would be generated by the Master Plans
alternative while the System Optimization "B" alternative would have
the lowest of all the alternatives.

     Under the No Build alternative, total vehicle miles travelled
to all the five airports will reach 4.1 million miles per day. 
Among the six alternatives, the No Build alternative generates the
second greatest (after the Master Plans) level of vehicle miles
travelled, and will create greater automobile emissions levels
related to surface vehicle traffic.  The No Build alternative will
create the second highest level of passenger trips over Bay bridges
(30,127-37,659) and on U.S. 101 at SFO, with almost 60 million
passengers travelling through SFO by 2010.

     An additional concern in evaluating the alternatives is the
potential impact which would occur in generating additional airport-
related traffic on highways adjacent to the airports.  These would
include U.S. 101 (the Bayshore Freeway) at SFO, Interstate 880 near
Oakland, and U.S. 101, Interstates 280 and 880, and SR 87 at San
Jose.  Although specific highway analyses were not done as part of
this system plan, the numbers in Exhibit 7.10 ("Daily Vehicle
Trips") can be used to estimate the impacts of the airport
development alternatives on adjoining highways.  For example,
traffic on U.S. 101 at SFO would likely be greatest under the No
Build alternative and least under the System Optimization "B"
alternative.  At Oakland, Interstate 880 traffic would

future levels of airline traffic and changes in the airline fleet. 
Both these are forecast by the FAA.  Indeed, the FAA also prepares
forecasts of the number of airline and commercial pilots, based on
its forecasts of future commercial flight activity.  However, the
future number of commercial and airline pilots retiring or leaving
the industry can be projected using a cohort approach from the data
on the number of active pilots by age group discussed above.  'Me
difference between the remaining active pilots and the number needed
by the FAA forecasts then represents the number of new commercial
pilots that will have to be hired.

     The results of this analysis suggest that the number of new
airline transport certificates that will have to issued per year
will increase from around 5,900 in 1995 to 8,000 in the Year 2000,
remain at this level until 2005, then increase to around 8,600 per
year in 2010.  'Me resulting number of new commercial pilot
certificates that will have to be issued per year will grow from
about 11,300 in 1995 to 13,100 in 2000, 15,300 in 2005, and 17,100
in 2010.  There were about 15,500 new commercial certificates issued
in 1990.  Thus it appears that the current entry rate of new
commercial pilots is in excess of the long-term demand, and will
result in an oversupply of qualified pilots.  This is likely to lead
to a leveling off or decline in the growth of commercial
certificates issued, particularly for pilots in the younger age
groups.  The number of active commercial pilots in the U.S. in the
age group from 20 to 24 has been increasing at around 13 percent per
year since 1987.  This clearly cannot continue indefinitely.  Thus a
plausible high growth scenario would have this rate drop to 6
percent per year until 1995, then reduce thereafter to 3 percent per
year, the estimated long-term rate of growth in required new
commercial pilots.  A corresponding low growth scenario would have
the growth reduce to 3 percent per year from 1990 to 1995, then to
zero growth thereafter.

Forecast Growth in Flight Activity

     Using the values of the cohort model coefficients given in
Tables 1 and 3 and the projections of the growth in the number of
pilots in the youngest age groups discussed above, the number of
active pilots in each age group can be projected for successive
future years.  Applying the average number of hours flown for each
age group from the data in Tables 1 and 2 then gives the total hours
flown in each year.  The results of these calculations are shown in
Table 4, for the four forecast years of 1995, 2000, 2005 and 2010,
expressed in terms of the growth from the hours flown in 1990.  The
values for the years 2005 and 2010 should be regarded with some
caution, as any errors in the cohort model will propagate into
successive years.  Also, by the year 2010, the number of pilots in
the four age groups from age 15 to 34 will be entirely dependent on
the validity of the projections of the number of entering pilots in
the youngest age group.

     Under the low-growth scenario, the annual hours flown by
commercial pilots increase by about 9 percent between 1990 and 1995. 
Thereafter, the growth rate reduces to give a further 4 percent
increase in each of the following five year periods, and a further 3
percent growth by 2010.  The annual hours flown by private and
student pilots reduce steadily, until by 2010 they

be most affected by the System Optimization "A" alternative, which
generates almost 48,000 daily trips, and would be least affected by
the New Technologies Alternative, which generates only half as many
daily trips.  At San Jose the Master Plans alternative would likely
have the greatest impact on adjoining roadways, while the New
Technologies alternative would have the least, generating only 75
percent as many daily trips as the Master Plans option.  These
traffic patterns are directly related to the regional airport shares
shown in Exhibit 7.1.

     In addition to determining the level of passenger-generated
traffic resulting from each alternative, the analysis included a
computer model of passenger mode split based on the 1990 MTC Air
Passenger Survey.  That analysis shows that construction of BART
connections to SFO only, to OAK only, or to both SFO and OAK would
result in both daily vehicle trips and daily vehicle miles travelled
(for these two airports) in the mid-range of the six alternatives. 
The impacts of the three BART connection options to San Francisco
and Oakland are displayed in Exhibits 7.9 and 7. 1 0.

5.      Air Quality

     The No Build alternative would produce a total of 60.18 tons of
carbon monoxide per day.

6.      Noise Impact

     The No Build alternative will reduce noise impact due to the
retirement of older, noisier, Stage 2 aircraft.  Total number of
residences within the 65 CNEL noise contour will decline from 7,401
residences in 1990 to 3,199 residences in the year 2010.  This falls
in the middle of the alternatives, which range from a high of 3,527
residences to a low of 2,694 residences.

7.      Wildlife/Wetland/Fill Impact

     The No Build alternative includes no new construction, and
would therefore cause no direct impacts to wildlife or wetlands, and
would require no new fill,

8.      Construction Cost and Impact

     The No Build alternative will include only the baseline costs
associated with airport improvement projects which are already
funded and approved.  These projects are included in all the
alternatives.

     As the baseline condition, the No Build alternative would not
involve any construction impacts beyond those associated with
currently approved and funded projects, as discussed immediately
above.  These impacts would occur under all the alternatives, and
would not provide the basis for discriminating between the system
plan alternatives under consideration here.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


9.      Economic Benefit

     As this alternative would not meet anticipated future air
travel demand in the region, it would have the least economic
benefit of any alternative.

10.     Implementation

     No specific actions are necessary to implement the No Build
alternative.

11.     Land Acquisition

     No new land acquisition is required for the No Build
alternative.

7.3.2   Airport System Management (ASK Alternative

     The ASM alternative evaluated the potential airside and
landside capacity gains that might be achieved by a variety of
aircraft fleet, airfield, and landside operational and management
measures, but not including any major construction.  These included
the following potential actions:

   1.   Improved air traffic control procedures from FAA
   2.   Improved navigational aids and lighting systems (MILS, etc)
   3.   Decreased  lateral  and  longitudinal  separations  between 
        aircraft  during  take-offs  and landings during VFR and IFR
        conditions
   4.   Improved apron operations management
   5.   Improved terminal and gate management
   6.   Increases in aircraft size
   7.   Increases in aircraft load factors
   8.   Voluntary or pricing methods to spread peak hour activity to
        non-peak hours
   9.   Diversion of general aviation activity to other airports

     These actions would require the direct involvement of the
airport operators, the airlines, the FAA, and other groups.  The FAA
would be responsible for implementing items 1, 2, and 3. Actions 4,
5, and 9 would be the responsibility of the airports.  Items 6 and 7
would be taken by the airlines.

     One of the key capacity issues in airport planning revolves
around peak hour demand and capacity.  Item 8, if it could be
implemented, would provide perhaps the most significant contribution
to improving the operation of the total regional airport system. 
This action would be implemented by the airports.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


     Although several of these actions could be taken, it is not
likely that all would be implemented.  The objective of the
alternative was to determine the maximum capacity gains possible if
the system was managed differently.

Following are the results of the ASM alternative evaluation:

1.      Runway Capacity and Delay

     All six air carrier alternatives are based upon the assumption
that some increases in aircraft size and aircraft load factor will
occur regardless of any actions taken by the region's airports. 
These are seen as independent industry trends, which will help to
increase capacity and improve the efficiency of the system over
time.  These improvements are therefore included as underlying
assumptions for all the alternatives.  In addition to those trends,
however, the ASM alternative includes actions aimed at obtaining the
maximum possible service out of the existing airport infrastructure.

     The combined affects of measures I through 5 could achieve a 10
percent increase in both airfield and landside capacity.  Items 6
and 7 varied by airport, but combined to achieve increases in
passenger capacity of between 8 and 11 percent.  In addition, items
8 and 9 resulted in 7-12 percent reductions in operational  parking
by improved flight scheduling.  It is the combined affects of these
actions that allow the ASM alternative to show significant advances
above the No Build alternative in meeting forecast demand
requirements.

     In total, the ASM alternative increases overall system landside
processing capacity from 53 million to 58 million passengers per
year in 2010 (9 percent); increases annual airfield capacity by
130,000 operations (6.5 percent); and decreases peak hour demand by
about 9 percent.  In spite of all these gains, the Airport System
Management alternative fails to meet forecast passenger or runway
demand in the year 2010 for either the high or the low forecast. 
The sum total gain from all the improvements described above would
bring San Francisco within its annual runway capacity.  All other
operational conditions for the ASM alternative do not differ
significantly from the No Build.  Clearly, system management
measures would be an important contributor to meeting the region's
future demand, but major capacity improvements in the airside,
landside, and airport access systems would still be required.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     The airport system management alternative will result in
slightly improved conditions in the region when compared to the No
Build alternative.  This will be the result of efficiencies achieved
through shifts in regional market share, limited increases in
operational capacity, and modest changes in aircraft size and
aircraft load factors.  Due to the shifting of demand to OAK


     7-25
     



     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


and SJC, however, annual landside processing capacities at those two
airports would be reached in the year 2000 under the high forecast
and between 2000 and 2005 under the low forecast.  San Francisco
would reach its annual passenger capacity by the mid- to late-1990s. 
The ASM alternative would, however, allow SFO to meet demand for a
few years beyond the No Build alternative.  Because of the shift in
passenger traffic to Oakland and San Jose, both these airports would
experience gate shortages by the year 2010.  Even though some of its
passenger traffic would be diverted to OAK and SJC, San Francisco
would also have a gate shortage by 2010 under both the low forecast
(12 gates) and the high forecast (31 gates).  Both Concord and
Sonoma County would have sufficient gate capacity to meet forecast
passenger demand through the year 2010.

Air Cargo Demand and Capacity

     The ASM alternative would not provide any new air cargo
facilities, and this alternative would therefore not meet projected
demand for air cargo activity.  Although some operational
improvements could be made to improve the efficiency and processing
ability of existing air cargo facilities, including apron space, the
ASM alternative would leave the region without the capability of
meeting regional air cargo demand.

General Aviation Based Aircraft

     The ASM alternative is not substantially different from the No
Build in providing for based aircraft.  Because some air carrier
activity would be relocated from SFO to SJC, however, there would be
less available runway capacity at SJC to serve general aviation
traffic.  The issue of general aviation aircraft basing at SJC,
however, will be determined not so much by the level of based
aircraft demand than on how much land area and runway capacity there
is to accommodate general aviation in addition to other airport
needs.

3.      Auto Parking Capacity

     The ASM alternative is not substantially different than the No
Build alternative in its provision of vehicle parking     .  Other
than the modest shifts in regional market share from SFO to OAK and
SJC, the ASM alternative suffers from the same severe parking     
shortages as the No Build.

4.      Airport Access/Distribution of Supply and Demand

     This alternative would slightly reduce traffic on Bay bridges
and U.S. 101 at SFO, but would increase traffic to OAK on 1-880 and
to SJC on U.S. 101, with resulting surface traffic and air quality
impacts in those areas.

     The ASM option would generate 3.9 million (high forecast) and
3.2 million ( Low forecast) daily vehicle miles travelled by
passengers.  This is 5 percent less than the No Build alternative.

     7-26
     
  


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


     Similarly, the ASM would generate some 17 percent less trips
across Bay bridges than the No Build.  The total number of daily
trips would not drop significantly under the ASM (only I percent
less than the No Build), but the trips would be shorter, and would
avoid the congestion on the bridges.  The ASM alternative takes a
step in the direction toward a more efficient distribution of
regional supply and demand.  This is seen as an important benefit of
the ASM alternative as compared to the No Build.

5.      Air Quality

     The major differences between the ASM and the No Build
alternative in terms  of  air  quality  are:

   a.   The ASM option will produce less total  vehicular-related
        emissions  than  the  No Build (54.77 daily tons of carbon 
        monoxide  (CO)  compared  to  60.18  daily  tons) due to its
        reduction in total vehicle miles travelled (5 percent), and;

   b.   The ASM  option  will  contribute  less  new  airport 
        traffic  to  major  congested regional highways (Bay bridges
        and U.S.  101)  because  it  redistributes  some  SFO traffic
        to OAK and SJC.

6.      Noise Impact

     The ASM alternative combined with airline fleet changes will
result in slightly fewer residences within the 65 CNEL noise contour
(3,161 residences) than the No Build alternative (3,199 residences). 
Compared with the No Build, the ASM alternative would result in
slight reductions in noise impacts at SFO and slight increases at
OAK and SJC.

7.      Wildlife/Wetland/Fill Impacts

     The Airport System Management alternative would involve no new
facility construction.  Therefore, no additional impacts on
wildlife, wetlands, or Bay fill are anticipated as a result of the
ASM alternative.

8.      Construction Cost and Impacts

     No major construction costs or impacts would result from the
ASM alternative.

9.      Economic Impacts

     The ASM alternative would produce slight increases in regional
economic benefits due to its slight increase in capacity.



     7-27
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


10.     Implementation

     Implementation of the Airport System Management alternative
will require a coordinated, cooperative commitment on the part of
the airports, the airlines, and the FAA to maximize the efficiency
of the existing airport system infrastructure.

11.     Land Acquisition

     No new land acquisition is required for airports in the 
Airport  System  Management  alternative.


7.3.3   Master Plans Alternative

1.      Runway Capacity and Delay

     The Master Plans alternative would provide sufficient annual
runway capacity to meet forecast operations demand at all airports
except San Jose, where annual runway demand would exceed capacity by
some 242,000 operations.  If general aviation demand were reduced by
this amount (some 86 percent of all GA operations) the airport would
stay within its planned annual capacity.  The general aviation
system plan alternatives evaluation (see Chapter 8) discusses where
these GA operations and based aircraft may be relocated.  San
Francisco, Oakland, and Concord would each be within 20 percent of
their annual runway capacity (annual service volume), and are
therefore classified as 'marginal" under the total annual delay
category in the evaluation.

     During peak hour, however, SFO, OAK, and SJC would all exceed
their hourly runway capacity during both VFR and IFR conditions for
both the low and high forecast.  This would result in unacceptable
delays to passengers and airlines.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     The current airport master plans would provide for capacity
improvements to meet all air carrier passenger demand through the
20-year planning period.  AR gate requirements would be met at each
of the five airports.

Air Cargo Demand and Capacity

     Air cargo demand would be met under the Master Plans
alternative at all airports.  Although constrained by its small
site, San Jose's maximum growth alternative would meet all passenger
and air cargo demand.  However, general aviation demand would exceed
capacity, requiring that

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


a portion of those needs (based aircraft, operations, and support
facilities) be met elsewhere in the region.

General Aviation Based Aircraft

    The Master Plans alternative would meet general aviation based
aircraft demand at all airports except San Jose.  As with the
analysis of annual runway capacity above, the Master Plan
alternative would be unable to meet San Jose's based aircraft
demand, falling some 66 percent short of that amount needed to meet
all forecast demand.  This alternative would result in the eventual
need to divert general aviation based aircraft and operations from
SJC to another airport in the county.  In addition, this alternative
could limit the potential for long range air cargo growth at SJC, if
all passenger demands are met.

3.      Auto Parking  Capacity

     All five airports will meet or nearly meet anticipated demand
for vehicle parking  for the low and high forecasts in the year
2010.  San Jose would require some parking  augmentation from off--
airport sources to meet all forecast parking demand (20,000 spaces). 
Concord would also need additional parking not now included in its
master plan to meet forecast demand.

4.      Airport Access/Distribution of Supply and Demand

     The Master Plans alternative would create the highest levels of
traffic on Bay bridges and U.S. Highway 101 at SFO.  This
alternative would generate approximately 4.1 million daily vehicle
miles travelled, a .4 percent increase above the No Build
alternative.  This alternative would also produce the most daily
trips (177,500), some 5 percent more than the No Build.  Similarly,
of the six alternatives being reviewed, the Master Plans alternative
would place the most daily passenger trips on Bay bridges (nearly
40,000), again some 5 percent more than the No Build, and 27 percent
more than the ASM alternative.  The Master Plan alternative includes
significant investment in surface and transit access improvements at
all the air carrier airports.  Of particular note are proposed BART
extensions to both San Francisco and Oakland.

5.      Air Quality

     The Master Plans alternative would result in .4 percent more
total daily vehicle miles travelled than the No Build alternative,
with a resulting increase in vehicle-generated emissions.  Total
daily pollutants (carbon monoxide) produced under the Master Plans
alternative would be 68.6 tons.  Transit access to SFO and OAK, as
discussed in the Master Plans, will provide an opportunity for long
term reduction in total passenger surface traffic, vehicle parking  
requirements, and vehicular emissions compared to accommodating the
demand without transit improvements.


     7-29
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


6.      Noise Impact

     The Master Plans alternative combined with airline fleet
changes would result in the highest number of residences within the
65 CNEL noise contours, primarily because it would continue to focus
growth at SFO.  The alternative would, however, reduce noise impacts
from 7,401 dwelling units in 1990 to 3,527 dwelling units in 2010.

7.      Wildlife[Wetland/Fill Impact

     The individual airport master plans have included reviews of
potential impacts on wildlife, wetland, and fill.  No significant
impacts have been identified as a result of the airport improvements
included in the currently approved master plans.  This assumes no
new runway at Oakland, and no new runways elsewhere.

8.      Construction Cost and Impacts

     Construction impacts related to implementing the airport master
plans include those from the runway extensions at OAK and SJC
(already completed), air cargo expansion at Oakland, and major
landside expansions at SFO, OAK, and SJC.

9.      Economic Benefits

     The Master Plans alternative would result in the highest
regional economic benefit as measured by total passenger activity.

10.     Implementation

     Most of the airport improvement projects included in the
current airport master plans will be implemented by the individual
airport operators with funding from the FAA, the airlines, passenger
facility charges (Pfc), parking and other airport-generated
revenues.

11.     Land Acquisition

     No major land acquisition would be required to implement the
Master Plans alternative.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


7.3.4   System Optimization Alternative "A"

1.      Runway Capacity and Delay

   With this alternative, all airports (except San Jose) would have
sufficient annual runway capacity and peak hour capacity in VFR
conditions to accommodate either the high or the low demand
forecast.  Oakland would construct a new parallel air carrier runway
at South Field.  This would increase the airport's total annual
capacity (annual service volume) from about 240,000 annual
operations to about 340,000 annual operations.  San Jose, because of
the high level of general aviation activity forecast, could not meet
the annual operational demand of general aviation.  Annual
operations demand at San Jose would exceed annual airfield capacity
by some 150,000 operations in the year 2010.  If general aviation
demand could be diverted from San Jose to another airport or
airports, the entire air carrier airport system would operate within
annual airfield capacity under this alternative.  Given the improved
distribution of supply and demand at the region's airports, this
alternative would provide enough peak hour VFR capacity to meet both
the low and the high forecast through the 20-year planning horizon
of this study.

     Demand and capacity under 'EAR conditions present a different
picture.  Even current (1990) demand under IFR conditions exceeds
the hourly IFR capacity that would be provided in the year 2010
under this alternative.  By the year 2010 this alternative would
experience a significant capacity shortage during IFR conditions,
resulting in delays at all airports except Sonoma County.  No
alternative by itself eliminates these IFR delays.  The primary
reason is because all three major airports (SFO, OAK,and SJC) would
lack sufficient distance between parallel runways (4,300 feet) to
allow simultaneous independent IFR operations.  This runway spacing
is not feasible given the size, location, and current configuration
of the three existing airports.  It its therefore inevitable that
the regional airport system will experience delays during poor
weather conditions.  Fortunately, IFR conditions occur a relatively
small percent of the time (7-12 percent), and occurs at different
times at different airports, thus reducing the likelihood of all
three airports having simultaneous IFR conditions.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     Under this alternative San Francisco's regional market share
would be reduced from 71 percent to 50 percent, while Oakland's
would increase from 13 percent to 26 percent, and San Jose's would
grow from 16 percent to 23 percent.  Improvements to both landside
and airside capacity at both OAK and SJC would be needed.  This
alternative would create the maximum level of passenger traffic at
OAK of the six alternatives, and may potentially result in some
limitation of air cargo at OAK, given the limited amount of upland
site available for future development at the airport.  Channelling
almost 20 million passengers through SJC, this alternative may also
tend to limit the ultimate (beyond the year 2010) amount of air
cargo growth potential there.

                                                7-31

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


     In addition, as with the Master Plans alternative, the System
Optimization "A" alternative would eventually require a major
relocation of general aviation activity away from SJC to make way
for passenger growth.

     This alternative would provide sufficient gates and other
passenger processing capacity to accommodate the high forecast
passenger demand through the 20-year planning period.  Under the low
forecast this alternative would have some excess capacity.

Air Cargo Demand and Capacity

     The System Optimization "A" alternative would redistribute air
carrier traffic such that San Francisco, Oakland, and San Jose could
accommodate forecast air cargo demand.

General Aviation Based Aircraft

     OAK, CCR, and STS would each meet forecast general aviation
based aircraft demand through the year 2010.  San Francisco (with a
30 aircraft deficit) and San Jose (with a 517 aircraft deficit)
would not.  These aircraft would eventually be displaced to other
airports.

3.      Auto Parking Capacity

     All vehicle parking demand would be met under the System
Optimization "A" alternative. 

4.      Airport Access/Distribution of Supply and Demand

     Total daily vehicle miles travelled under the high forecast for
this alternative would be 3.7 million, some 10 percent less than
both the Master Plans and the No Build alternatives.  The System
Optimization "A" alternative would also generate about 8 percent
less total daily trips to the region's airports than the Master
Plans alternative.  This alternative would cause a significant
reduction in passenger-generated traffic on the Bay bridges and U.S.
101 at SFO.

     This alternative would necessitate the construction of major
access improvements to Oakland airport, such as the Airport Roadway
project and the planned BART connection, to help ease the potential
congestion on I-880, Hegenberger Road, Airport Drive, and other
roadways serving the airport.  Traffic improvements at San Jose
would also be required.

5.      Air Quality

     This alternative would produce only slightly more pollutants
(carbon monoxide) per day (60.47 tons compared with 60.18 tons) than
the No Build.



     7-32
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


6.      Noise Impact

     This alternative, when combined with airline fleet changes,
would result in a reduction in the number of residences located
within the 65 CNEL noise contours from 7,401 residences in 1990 to
2,797 residences in the year 2010.  This is the second lowest of the
six alternatives.

7.      Wildlife/Wetland/Fill Impact

     The System Optimization "A" alternative would involve
construction of a new parallel runway and taxiway at OAK.  This
would require the filling of between 124 acres (for the inboard
alternative) and 135 acres (for the outboard alternative) of
freshwater wetlands, and would also include some 57 acres of
saltwater wetlands in San Francisco Bay for the outboard runway
alternative

8.      Construction Cost and Impact

     System Optimization Alternative "A" would have moderately high
construction costs and impacts when compared with the No Build and
ASM alternatives.  These costs and impacts would be similar in
magnitude to the Master Plans alternative, but would focus more cost
and construction impacts at OAK and SIC.

9.      Economic Benefit

     This alternative would create moderately high regional economic
benefit.

10.     Implementation

     Similar to the Airport System Management alternative,
implementation of the System Optimization 'A' alternative will
require a coordinated commitment on the part of the airports, the
airlines, and the FAA to maximize the efficiency of the existing
airport system infrastructure.

11.     Land Acquisition

     No new land would need to be acquired for the System
Optimization 'A' alternative.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


7.3.5   System Optimization Alternative "B"

1.      Runway Capacity and Delay

     Under System Optimization Alternative "B" SFO, OAK, CCR, and
STS would each have excess total annual runway capacity through the
year 2010 while SJC would reach annual runway capacity in the year
2000.  This is because of the demand for general aviation operations
at SJC.  If roughly half this general aviation traffic (140,000
annual operations) could be diverted to other non-air carrier
airports, San Jose would remain within its annual airfield capacity,
though it would still experience marginally acceptable delays during
peak hours.

     One of the key underlying assumptions of the Optimization 'B'
alternative is the diversion of passenger and air cargo activity
from existing overcrowded airports (mainly San Francisco) to a sixth
air carrier airport (fourth major air carrier  airport).  Evaluation
of the results of the "ACCESS" model reveal that a new airport at
Travis will draw only about 8 percent of the total regional
passenger market, or 6.4 million annual passengers in the year 2010. 
This would still mean that for SFO, OAK, and SJC, peak hour
capacities would be exceeded during both VFR and IFR conditions,
leading to unacceptable delays.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     Optimization Alternative "B" would develop a new civilian air
carrier airport at Travis AFB (sharing existing runway and air
traffic control with military aircraft activity), and redistribute
regional passenger market shares.  This option would divert
passenger traffic primarily away from SFO, and to some extent from
Sacramento.  In contrast to System Optimization "A", this
alternative would take passenger traffic which would have been
diverted from SFO to OAK and re-divert that traffic to Travis.  This
accounts for the difference in Oakland's market share under option
"A' (26 percent) versus under option "B" (21 percent).  If service
is developed and flight frequencies maintained comparable to Oakland
and San Jose airports, the new airport at Travis AFB would command
about 8 percent of the total regional passenger traffic in 2010.  Of
this 8 percent, about 5 percent is traffic diverted from Oakland and
3 percent is traffic diverted from SFO.  This option would provide
enough gates to handle forecast passenger traffic through the year
2010, with Oakland adding some 23 new gates, San Jose adding 18, and
some 20 gates being constructed at Travis.

     This option would still result in limits to future air cargo
growth as well as the eventual displacement of much general aviation
activity at SJC.

Air Cargo Demand and Capacity

This alternative would meet all forecast air cargo demand.

General Aviation Based Aircraft

     General Aviation based aircraft demand would be met at all
airports except SFO and SJC.  San Francisco would accommodate 46
aircraft (as provided in the airport master plan), while the based
aircraft forecast shows demand for 76 based aircraft.  San Jose
would fall far short of the based aircraft need, with a 2010 demand
of 785 aircraft and a capacity of only 268 (as outlined in the
current master plan).

3.      Auto Parking Capacity

     Vehicular parking would be provided in the Optimization "B"
alternative at each airport sufficient to meet all forecast demand
through the year 2010 for both the low and the high forecasts.

4.      Airport Access/Distribution of Supply and Demand

     Total daily vehicle miles travelled for this alternative would
be 3.5 million.  This is the most efficient of all the alternatives
in terms of this parameter, generating 15 percent less surface
vehicle, miles travelled than the Master Plans alternative, and 6
percent less than the Option 'A' Alternative.  Much of this
reduction is because passengers from Solano, Napa, and Contra Costa
Counties could greatly reduce their airport commute distances. 
Option "B" would generate the second lowest number of total daily
airport passenger trips (162,037).  This option would result in
reduced regional levels of surface vehicle-generated emissions in
comparison to the other alternatives, and would have the lowest
level of passenger traffic on Bay bridges (21,221) and U.S. 101 at
SFO.  With the possible future addition of BART service to both San
Francisco and Oakland, the Optimization "B" alternative has the
potential for even greater reductions in airport generated surface
traffic and related congestion and emissions.

     Although the Optimization 'B' alternative would increase
traffic at Oakland and San Jose when compared with the No Build
alternative, it would divert a significant level of traffic away
from San Francisco, thereby reducing total airport traffic and
traffic-related emissions.  When compared with the Optimization "A"
alternative, this alternative would generate 20 percent fewer daily
trips to Oakland, diverting them to Travis instead.

5.      Air Quality

     This alternative would produce 59.95 tons of carbon monoxide
per day, the second lowest of all the alternatives.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


6.      Noise Impact

     This alternative, combined with airline fleet changes, would
have the lowest number of residences within the 65 CNEL noise
contours, with the total regional number falling from the 1990 total
of 7,401 residences to 2,694 residences in the year 2010.

7.      Wildlife/Wetland/Fill Impact

     Some wildlife, wetland, and fill impacts may result from the
future development of Travis AFB into a joint military-commercial
service airport.

8.      Construction Cost and Impact

     Construction of new access roads, parking, terminal facilities,
and other support facilities at Travis could result in moderately
high construction costs and impacts when compared with the No Build
and ASM alternatives.

9.      Economic Impact

     This alternative would create moderately high regional economic
benefit.

10.     Implementation

     Similar to the Airport System Management alternative,
implementation of the System Optimization "B' alternative will
require a coordinated, cooperative regional commitment on the part
of the airports, the airlines, and the FAA to maximize the
efficiency of the existing airport system infrastructure.

11.     Land Acquisition

     Some land acquisition and/or easements may be needed around
Travis AFB in order to allow for long term commercial service
(passenger flights), to protect approaches, and to prevent potential
noise-sensitive land uses from being developed in currently vacant
land surrounding the airport.

7.3.6   New Technologies Alternative

1.      Runway Capacity and Delay

     This alternative would reduce passenger traffic at all five
airports, although its affect would primarily be felt at SFO, where
total annual passenger traffic would be reduced by some 6 million
passengers in the year 2010.  This would help to maintain SFO within
its annual airfield capacity.  Oakland, Concord, and Sonoma County
would also be within their annual runway capacity.  San Jose would
experience demand in excess of annual capacity, again due to the
high level of general aviation demand.

     Under this scenario, SFO peak hour passenger demand would
exceed runway capacity during both VFR and IFR conditions.  Oakland
and San Jose would each be within their hourly runway capacities
during VFR conditions, but would not be able to accommodate peak
hour demand during IFR conditions.  Peak hour delay during IFR
conditions would be unacceptable for all three major air carrier   
airports, as well as Concord.  Sonoma County could accommodate both
annual and peak hour demand in all weather conditions.

2.      Landside Capacity

Passenger Capacity and Gate Requirements

     The new technologies alternative would divert a maximum of 10
percent (8.5 million passengers in 2010) of the region's total
passenger traffic to a high speed rail system linking the Bay Area
and Southern California.  This level of traffic would only be
possible if the rail system could be priced competitively, and
operated at cruising speeds of up to 200 U?H.  This speed would be
necessary in order to keep travel times between the Bay Area and
Southern California under two hours.  Presently about 30 percent of
all traffic from the three major Bay Area airports (12 million in
1990) is bound for the Los Angeles and San Diego areas.  Of this
traffic, the New Technology alternative assumes that one third
(between 7 million and 8.5 million annual passengers in the year
2010) can be diverted to a high speed rail system.  The New
Technologies alternative then allocates all remaining passenger
traffic (63 million to 76 million annual passengers) to the five
airports based on existing market shares.  Of the five airports,
only San Francisco would have insufficient aircraft gates to meet
gate requirements in the year 2010.

Air Cargo Demand and Capacity

     In maintaining the 1990 regional market shares, this
alternative would allow for some air cargo growth at SIC, and
significant growth in air cargo at OAK.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


General Aviation Based Aircraft

     All based aircraft demand at the five air carrier airports
would be met under this alternative except for San Jose, which would
still have a capacity shortfall.

3.      Auto Parking Capacity

     This alternative would provide sufficient vehicle parking
capacity at all five air carrier airports to meet projected parking
demand through the year 2010.

4.      Airport Access/Distribution of Supply and Demand

     This alternative used existing regional market shares in order
to test how much traffic could be diverted away from the existing
airports, and how well the existing  airport system would perform
with the resulting lower passenger demand.  The new technology
alternative would reduce traffic at all five airports as compared to
the No Build alternative, but would generate new passenger traffic
between passenger origins and destinations at the new rail stations
or vertiports.  The "ACCESS' model was unable to evaluate the New
Technology alternative in the same way as the other alternatives. 
Therefore, no figures on vehicle miles travelled or daily vehicle
trips were available from the 'ACCESS" model.  The analysis used
here is based on the assumption that total vehicular traffic to the
high-speed rail stations or vertiports will be approximately the
same but slightly less than traffic to the airports.

     As the existing airports are somewhat centrally located in
relation to the regional population, it is assumed that the new high
speed rail stations would also be located at sites easily accessible
to the passengers.  These stations would also need to be convenient
to passengers in order to compete with air travel.  The analysis
shows that total daily trips and vehicle miles travelled would be
slightly less than the No Build alternative.  This is the result of
two factors: (1) the new technologies alternative would divert
passenger traffic from the three airports, and trips diverted to the
rail stations or vertiports would likely be shorter than those to
the airports.

     There are two reasons for this: (1) the rail stations would
probably be located closer to BART and the regional freeway system
than SFO and OAK, thereby reducing the length of those trips; and
(2) vertiports would likely be located at a combination of
locations, including existing air carrier airports, GA airports, and
other decentralized locations, thus reducing most trip lengths. 
Total daily trips and daily vehicle trips at SFO, OAK. and SJC would
therefore each be reduced somewhat as compared to the Master Plans
and No Build alternatives.

     Based on the assumption that average trip lengths to high speed
rail stations or dispersed vertiports would be three miles less for
passengers diverted from SFO and five miles less for passengers
diverted from OAK, the New Technologies alternative would generate a
daily total of 4 million vehicle miles travelled under the high
forecast, some 1 percent less than the No

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


Build.  A finding of the analysis is that the New Technologies
alternative would generate less traffic on Bay bridges, some 7
percent less than the Master Plans alternative, and 2 percent less
than the No Build alternative (see Exhibit 7.11).

5.      Air Quality

     The New Technologies alternative would result in the lowest
production of total regional carbon monoxide (56.81 daily tons).

6.      Noise Impact

    The New Technologies alternative, combined with airline fleet
changes, would have the third lowest number of residences within the
65 CNEL noise contours (3,015 residences), with only the two System
Optimization Options 'A' and "B' being lower.

7.      Wildlife/Wetland/Fill Impact

     The New Technologies alternative could potentially result in
numerous environmental impacts related to acquisition of right-of-
way and construction of the 300 to 400 mile high-speed rail system.

8.      Construction Cost and Impact

     This alternative could result in the highest cost of all the
alternatives, primarily because of the cost associated with
construction of the 300-400 mile high speed rail system.  If
existing right-of-way were used, both construction cost and impacts
could be significantly reduced.

9.      Economic Impact

     The New Technologies alternative has the potential to create
the greatest economic benefit, in that it would provide for airport
expansion in the region as well as providing a new transportation
system connecting central and southern California.  It is highly
likely that communities located along the rail corridor would
experience economic benefit from the construction and operation of
the rail system.  These benefits could increase in the future if
additional passenger traffic were captured by the system.

10.     Implementation

     Implementation of the high-speed rail or vertiports alternative
would require a number of actions by agencies statewide.  These
would include Caltrans, the airports where vertiport service was to
be introduced, the FAA, local governments affected by construction
and operation of the high speed rail system, etc.

MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


11.     Land Acquisition

     The New Technology alternative would likely involve the
greatest amount of land acquisition of all six alternatives.  This
land acquisition may be necessary for the high-speed rail right of
way, unless an existing railroad, utility, highway, or other
appropriate right of way can be found.  This right-of-way, which
would be in the range of 350-450 miles long, could be very costly,
and may result in some displacement of existing property owners. 
Land acquisition may also be needed in the Bay area for construction
of the rail stations and access routes and parking facilities to
serve them.


7.3.7   Civilian Use of Alameda NAS and Moffett NAS

     Civilian use of these two military facilities was evaluated in
the regional system planning process as a possible method of
diverting traffic away from Oakland and San Jose.  The following are
initial conclusions:

Alameda NAS

   1.   Has limited potential for some air carrier use due to
        airspace  conflicts  with  OAK.  Flight paths  dictate  a 
        one-for-one  tradeoff  between  flights  at  OAK  and 
        Alameda  NAS.  This would limit the potential for any
        significant gains in regional capacity.

   2.   Has limited potential for  diverting  some  all-cargo  air 
        cargo  activity  away  from  OAK, particularly considering 
        the  lack  of  good  connections  to  the  regional 
        transportation system.

   3.   Has potential obstruction  problem  from  the  Bay  Bridge 
        during  IFR  arrivals  under  the southeast plan.

   4.   Has a slight advantage over  OAK  in  terms  of  land  use 
        compatibility  in  the  immediate area  around  the  NAS. 
        Noise  issues  would  likely  still  remain,  with  possible 
        major objections from Alameda and other local residents.


Moffett NAS

   1.   Similar to the  Alameda  NAS-OAK  airspace  situation,  air 
        carrier  use  of  Moffett  Field would likely also be faced
        with a  one-for-one  operations  tradeoff  with  SJC.  This 
        would limit the potential for any substantial gains in system 
        capacity,  and  would  increase  the complexity of regional
        airspace.


     7-40
     
     


MTC Regional Airport System Plan Update
Chapter 7: Air Carrier Alternatives Evaluation      September 9, 1994


   2.   Has good potential for general aviation use, particularly
        corporate aviation.

   3.   Has potential for better land use compatibility than SJC due
        to less noise sensitive uses in immediate vicinity.

   4.   Has good access from U.S. 101, which could be further
        improved if needed.

   5.   Civilian use would conflict with NASA's continued use of the
        facility based on current NASA policy.

8  GENERAL AVIATION ALTERNATIVES EVALUATION

8.1     Introduction

     This chapter contains three major sections: (1) a brief
description of the general aviation system alternatives that have
been considered; (2) a discussion of the alternatives evaluation
methodology; and (3) a summary of the evaluation results.  The
methodology section includes a list of assumptions, a discussion of
the allocation of based aircraft, and a summary of data sources
used.  Based aircraft are the key ingredient of the analysis, since
they are the basis of aircraft parking and other support
requirements.  In addition, operations demand is derived from based
aircraft.

8.2     Description of General Aviation Alternatives

8.2.1    No Build Alternative

     As with the air carrier alternatives, the No Build alternative
for the general aviation system serves as a baseline for comparison
of the Master Plan and System Optimization alternatives.  The
underlying premise of this alternative is to evaluate how the
existing general aviation system would perform under future
conditions with no major airport improvements or capacity
enhancements.  The No Build alternative therefore consists simply of
the existing airfields as they exist in the base year (1990) with no
improvements.  Existing airfield, based aircraft storage, itinerant
aircraft parking, and all other landslide facilities would remain as
they are in 1990, with capacity remaining at current levels.

Only three changes are assumed to be in place under this
alternative:

        (1)       A slight shift in the regional distribution of 
        based  aircraft  demand  due  to  shifts  in regional
        population and the locations of aircraft owners. This is
        reflected  in  the  demand for based aircraft at each
        airport.

        (2)       A shift in the type of based aircraft  storage 
        demand  from  current  conditions,  with  an increasing
        demand for hangar space.

        (3)       An increase in the average aircraft utilization
        over time. This is reflected in an  increase in annual
        operations per based aircraft from 500 in 1990 to 531 in the
        year 2010.


     The No Build alternative assumes that San Jose continues to
meet as much GA demand as existing facilities can accommodate; Reid-
Hillview remains open; Moffett Field remains in use as an exclusive
NASA-related facility and not available for use by civil general
aviation; and Hamilton Field is unavailable due to lack of an
airport operator.

MTC Regional Airport System Plan Update
Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

8.2.2  Master Plans Alternative

     The Master Plans alternative is a composite plan consisting of
the individual airport master plans for each of the 24 primary
airports in the general aviation airport system.  In cases where
there was no current, approved master plan for an airport, demand
allocations (and the resulting need for airport improvements) were
made based on the airport's assumed regional market share as
described above in the assumptions section.

     In several cases, this alternative differs from the other
alternatives evaluated in that the anticipated demand (either
operations or based aircraft) at individual airports may be higher
or lower than that assumed under the No Build or System Optimization
alternatives.  Higher forecasts in the master plans in most cases
are due to more aggressive master plan policies and development
strategies than those assumed in the other alternatives.  Lower
master plan forecasts may be due to constraints placed on the
individual airport for noise control or other purposes.

     Key elements of this alternative include the following
assumptions: San Jose reduces general aviation operations and based
aircraft; Reid-Hillview remains open at its current level of
activity; Moffett Field is used by NASA as described above in the No
Build alternative; Hamilton Field will not be available; and most
growth in both demand and supply occurs at the major general
aviation facilities, including Sonoma County, Nut Tree, Byron,
Concord, Livermore, and Hayward.

     Because of the low level of general aviation activity at San
Francisco International Airport, SFO is omitted from the GA
evaluation.  This alternative contains the same assumptions for
Moffett and Hamilton Fields as in the No Build alternative.

8.2.3  System Optimization Alternative

The System Optimization alternative is based on achieving the
following major objectives:

        1    To  alleviate  congestion  at  close-in  air  carrier 
        airports  which  operate  in  restricted airspace, thereby
        allowing those airports to  better  meet  passenger  and  air 
        cargo  demand. This is the function of the general aviation
        'reliever' system.

        2.   To  achieve  efficient  use  of  existing  airport 
        capacity,  concentrating  activity   at   those airports 
        which  can  accommodate  it  without  adverse  impacts  on 
        neighboring  communities.

        3 .  To effect a more efficient regional balance in the
        distribution of based aircraft  in  relation to  aircraft 
        owners  to  improve  user  convenience   and   minimize  
        environmental   impacts associated with access to and from
        the region's airports.

Chapter 8: General Aviation Alternatives Evaluation September 9, 1994
                

     In order to accomplish these objectives, this alternative
envisages capacity expansion at a limited number of peripheral
airports: Sonoma County, Nut Tree, Byron, Livermore, and South
County (either at the existing South County airport or at a new
airport in south Santa Clara County).  Regional airport investment
strategies would be prioritized to favor investment and development
of these airports.  Land use control measures would be undertaken to
ensure a wide buffer of airport-compatible land uses around these
airports to safeguard their future growth potential.  Under this
alternative San Jose would reduce general aviation; Reid-Hillview
would be retained with its current capacity; and Hayward would
reduce its activity levels by the diversion of flight training and
recreational activity to the peripheral airports.  General aviation
activity at Concord and Napa County would expand to the levels
consistent with their master plans.

Moffett Field would be retained in its current status as an
exclusive NASA facility.

8.3     GENERAL AVIATION ALTERNATIVES EVALUATION METHODOLOGY

     The evaluation methodology for the General Aviation
Alternatives addressed three issues: the selection of the evaluation
criteria to be used, the assessment of the relative performance of
each alternative under each criterion, and the presentation of the
results of this analysis as a basis for selecting a preferred
alternative.

8.3.1  Evaluation Criteria

     Similar to the air carrier alternatives criteria described
above in Chapter 7, the following describes the evaluation criteria
used in evaluating the general aviation system alternatives.

Airside Capacity (Runways)

     Airside (runway) capacity, expressed in terms of Annual Service
Volume, was compared to forecast number of annual operations by
airport and for the entire system.

Operations

     This criterion measures how well the system provides for safe
and unobstructed operations during a variety of weather conditions. 
Measures include:

   -    Removing and/or making obstructions to airspace (Part 77,   p
                                                                    r

MTC Regional Airport System Plan Update
Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

Landside Capacity (Aircraft facilities)

Based aircraft demand was compared  to  based  aircraft  capacity, 
using  the  following  measures:

   -    Aircraft tie-downs 
   -    Itinerant apron 
   -    Hangar space
   -    Total based aircraft.

Distribution of Demand and Supply

     This criterion evaluated the extent to which each alternative
meets the needs of general aviation aircraft operators and users, so
as to efficiently utilize both the airport system and the regional
highway system.  The regional balance of demand and supply will be
evaluated using two measures:

   -    The total highway travel time involved in access/egress     t

     Since there are no airports in San Francisco County itself, San
Francisco International Airport (actually located geographically
within unincorporated San Mateo County) was treated as being in San
Francisco County for the purposes of the analysis.

Noise Impacts

     This criterion establishes the relative noise impact for each
alternative based on the total area (in acres) within the estimated
65 community noise equivalent level (CNEL) noise contours and
outside the airport property line.

Compatibility with Local Government Land Use Planning

     The compatibility of the different alternatives with existing
local government land use planning is related in part to noise
impacts, but clearly goes well beyond the extent of specific noise
contours.  Appropriate measures might include the number of airports
that would not be covered by existing approved airport land-use
plans under the alternative, or acres of incompatible land use
within a designated impact area for each airport.

Capital Cost

This criterion compares the land acquisition and construction costs
involved  in  each  alternative.

Bay and Wetland Fill

     The total number of acres of bay and/or wetland fill (if any)
associated with each alternative was determined based on existing
data in master plans, EIS documents, etc.

Air Quality

     Under this criterion, the total amount of air pollution
produced in the system by surface vehicle traffic associated with
general aviation operations was assessed for each alternative, based
on total surface vehicle miles traveled and average speed.  Since
the total amount of aircraft activity in the region is the same for
each alternative, there is no difference in the air quality impact
due to operation of aircraft across the different alternatives.

Operations Cost

This criterion addressed the expected operating costs involved in
each alternative.

Emergency Response

     This criterion looks at the ability of the general aviation
airports in the regional system. to support emergency response
needs, using as a measure the average distance from the nearest
airport of the population in the region.  Because of the possible
loss of the Bay and Sacramento River bridges in a major disaster,
the nearest airport will be determined using routes that do not
cross those bridges.

8.3.2   Evaluation Methodology

     In order to evaluate the performance of the different
alternatives, a Demand Allocation Model was developed to estimate
based aircraft at each airport, under both the low and high growth
assumptions identified in the GA forecasts, and given the geographic
distribution of their owners across the region.

     Knowing the distribution of the based aircraft, the regional
forecasts of aircraft activity (local and itinerant operations) can
be allocated to airports on the basis of the number of operations
per based aircraft.  While this could simply be done using regional
average values of operations per based aircraft, this would not give
a very realistic allocation, since those aircraft that are used more
intensively are likely to be based at the more convenient airports. 
Improved activity estimates can be obtained by classifying the
aircraft into use categories, on the basis of aircraft type and
whether privately or corporately owned.  Data on use by these
categories is available from FAA aircraft activity surveys.

     The number of highway trips generated by each based aircraft
per year will depend on the number of itinerant operations and the
number of local hours flown and the average flight duration.  In
general, each training flight will generate two highway trips to the
airport, one for the instructor and one for student.  The instructor
may fly several times in one day, or some days travel to the airport
but make no flights at all.  Without taking the time to study this
issue in detail, it will be assumed that each training flight
generates two highway access trips, while other flights generate
one.  The number of highway trips generated by each aircraft can be
combined with the based aircraft allocation results to determine the
total amount of access/egress travel time and the number of trips
from each analysis zone to each airport.

     Using the results of the analysis described above, the
individual airport values for each of the evaluation criteria were
aggregated into region-wide totals for each alternative scenario. 
Where qualitative descriptions were used for an evaluation
criterion, the regional summary combines the more significant
comments for the individual airports.  The resulting data show the
regional totals for each of the quantifiable criteria for each
alternative scenario, together with supporting tables showing the
airport-level results (see Exhibits 8.1 through 8.17).

Assumptions

The following assumptions are inherent in the evaluation
methodology:

1.     Shift in Regional Distribution of Based Aircraft

     The regional distribution of based aircraft is assumed to shift
differently under each system alternative.  For the No Build
alternative regional based aircraft distribution will be similar to
the current distribution (1990 Existing Conditions), but will shift
slightly due to forecast shifts in the regional location of aircraft
owners.  In general, aircraft ownership has been shifting toward the
North Bay area in recent years, and this trend is expected to
continue.  For the Master Plans alternative the region's based
aircraft will be distributed similar to that of the No Build, but
with some changes as contained in the individual airport master
plans.  For the System Optimization alternative, more significant
shifts in the regional distribution of based aircraft are expected. 
These shifts include those forecast to occur due to changes in the
locations of aircraft owners as well as other direct changes
resulting from policies and programs contained in the system plan.

2.     Shifts in Type of Aircraft Storage Demand Toward Hangars

     The regional based aircraft demand will shift slightly over
time away from open tie-downs toward covered/enclosed hangars, while
itinerant demand will grow from its current share of 7 percent to 8
percent.  The regional distribution of demand among these three
types of aircraft parking for 1990 and forecast for 2010 are as
follows:

   Type if Aircraft Storage           1990           2010

   Open Tie-downs                     56%            52%
   
   Hangars                            37%            40%

   Itinerant spaces                    7%             8%

TOTAL                                 100%           100%


   *    Total based aircraft demand consists of open tie-downs plus 
        hangars.  Total aircraft parking demand consists of open tie-
        downs plus hangars plus itinerant.

     This assumption is based on information from pilots and airport
operators that hangar space is currently full (the Existing
Conditions spreadsheet shows that of 2,295 hangar spaces, some 2,293
are currently occupied by based aircraft), while open tie-downs are
largely under utilized (based on data collected by CALTRANS and TRA
Airport Consulting in early 1993 the region had only 3,742 based
aircraft using tie-downs, while the region's tie-down capacity was
nearly 5,600 spaces).  There is significant anecdotal evidence
throughout the region that new aircraft hangar space is rented very
shortly after it is built, while existing open tie-downs go vacant,
even when there is a price differential between hangar and tie-down
space.  This indicates a latent demand for hangar space throughout
the region.

     In addition to the above, the alternatives evaluation assumes
that the demand for based aircraft storage space does not include
itinerant aircraft parking.  Therefore, the evaluation of based
aircraft demand versus capacity has been done by comparing actual
based aircraft with open tie-downs and hangars.  Itinerant parking
positions represent an additional demand which is supplemental to
based aircraft parking demand [* see note at bottom].


3.    Forecast of Aircraft Operations for Each Airport

     The general aviation element of the Regional Airport System
Plan is built around the forecast of based aircraft and the
distribution of based aircraft throughout the region.  The number of
aircraft operations forecast for each airport is therefore derived
from the number and type of aircraft based at that airport.  With
the nationwide decline in general aviation activity in the past 10
years, the level of aircraft utilization (amount of time each
aircraft is flown each year) has fallen.  In the plan's base year,
the number of annual operations per aircraft for the total region
had fallen to about 500.  While forecasts of future GA activity show
increases in both the number of based aircraft and the number of
operations, the growth in operations is expected to grow faster than
the number of based aircraft.  This reflects the expectation that
each aircraft will be used more (flown more hours and perform more
take-offs and landings per year) than it is today.  With the overall
shift away from recreational and discretionary flying and toward
corporate and business flying, this trend seems appropriate.  With
this expectation, the operations forecasts for each airport were
based on the number of operations per based aircraft (OPBA)
increasing from about 500 per year in 1990 to between 511 and 560
per year in 2010.  The "total annual operations demand" figures on
line (1) of each spreadsheet (see Exhibits 8.1 through 8.17) reflect
these assumptions.


   *     [Note: For this reason the figures in lines (10), (11), and
        (12) in each spreadsheet add up to more than the total based
        aircraft demand shown in line (9).  Line (9), which displays
        total based aircraft demand indicates the total of open tie-
        downs plus hangar demand, but does not include itinerant
        demand as shown on line (12).  Thus the total based aircraft
        demand figure shown on line (9) will equal the sum of lines
        (10) plus line (11).]

Allocation of Based Aircraft

The aircraft location decision depends primarily on the following
factors:

   -    distance from home or place of business
   -    availability of hangar space 
   -    hangar/tie-down rental fees.

     In addition, the following factors may need to be considered in
the demand allocation process, although they may not be a
significant factor at present:

   -    availability of tie-downs 
   -    lighting and navigation aids 
   -    runway length and width
   -    Fixed Base Operator (FBO) facilities.

     Presumably the existence (and hours of operation) of a control
tower is also a factor in the decision for at least some owners.

     As noted before, every airport in the region currently has
vacant tie-down spaces while no airport has empty hangar space.  New
hangars are under construction at Sonoma Skypark and there are plans
to add hangars at Gnoss Field in the near future.  While tie-down
space availability is not an issue at present, this may change if
some airports close.  The availability of lighting and navigation
aids may be less important for owners of aircraft used primarily for
recreation than for other purposes, while runway length and width
may restrict where larger aircraft can be based.  Availability of
FBO facilities may also be a factor in the location of corporate or
business aircraft.

     Since every airport has vacant tie-down spaces, this suggests
that (at least in principle) any aircraft owner could choose to base
his or her aircraft at any airport.  Classic discrete choice theory
would hold that for any given owner, each airport offers a "utility"
that is a function of its location and other attributes (such as
fees).  In addition to direct costs, such as hangar fees, and the
cost of the travel required to get to the airport (including the
value of the time involved), the other attributes discussed above
can be thought of in terms of equivalent costs, even if only as a
measure of the inconvenience of having to go to another airport for
FBO services or not being able to operate at night or in bad
weather.

     Data Sources (see also bibliography)

     There are three different data sources that address the
distribution of aircraft and aircraft owners in the region.  First,
the FAA distributes a list of aircraft by county of registered
owner.  This is derived from aircraft registration data and is
updated annually.  The information includes the aircraft
registration number (tail number), the manufacturer and model, and
the address of the registered owner.  However, this data set does
not contain the location where the aircraft is based.

     Secondly, each airport reports the number of based aircraft in
seven categories (e.g. single engine piston) to the FAA
approximately every year as part of the regular airport inspection
program.  These data are available on the FAA Form 5010 that is
maintained for each airport.  In addition, airports also maintain
tenant lists that typically include the tail number of the aircraft
and the address of the owner, as well as the specific facility
leased (e.g. tie-down space).  However, if a tenant subleases space
to an aircraft owner, the airport may not know (or may not record)
the identity of the aircraft occupying the space.  There is
currently no central database of tenant lists, and the information
must be obtained directly from each airport.  While airports are
generally willing to provide current lists, these turn over
continuously, and historical data may not have been preserved.

     Finally, the County Assessor for each county maintains a list
of aircraft based in the county for property tax purposes.  The data
generally includes the tail number, the address of the aircraft
owner, the manufacturer, model and year (to determine the assessed
value), and the location where based (often termed the situs).  The
situs may be expressed as an airport, an address, or a parcel number
(from which the location can be determined by reference to the
county parcel map).  The Division of Aeronautics of the California
Department of Transportation (Caltrans) attempts to maintain a
central database of County Assessor aircraft records for all
California counties.  However, the files are often in different
formats for each county and are frequently incomplete.  Further,
there is believed to be a considerable amount of misreporting of
aircraft location by owners trying to minimize (or avoid) property
taxes.

     County Assessor data files for each of the nine Bay Area
counties were obtained from Caltrans and assembled into a
consolidated database.  Aircraft manufacturer and model codes were
standardized and aircraft type codes added.  Owner zip codes were
checked against cities and a number of incorrect zip codes were
identified and corrected.  Owners were classified into several
categories (e.g. individual, corporation, flying club, etc.) based
on the owner name, and an owner type code added to the file. 
Aircraft situs location codes were converted to a standard set of
airport codes.  Highway travel times to each GA airport from each
regional analysis zone were obtained from the MTC regional highway
network files for 1990 a.m. peak conditions.  Since aircraft owner
locations are expressed as postal zip codes, a conversion table was
created to identify the corresponding MTC analysis zone for the
centroid of each zip code area, and a zip code to airport travel
time matrix developed.

     Airport hangar and tie-down rates were obtained from the
Caltrans Division of Aeronautics Public.Use Airport Inventory
database, supplemented with data from a survey of rates at selected
California airports conducted in April 1991 by staff of the
Sacramento County Department of Airports, and data obtained directly
from Bay Area airports.

     Projection of the future distribution of based aircraft in the
region requires a methodology to assign owner locations to a
forecast number of based aircraft.  In addition to changes in the
distribution of based aircraft across airports, the distribution of
owner locations will presumably also change to reflect regional
changes in population distribution.  This future distribution of
aircraft owners was held constant for all three general aviation
airport system alternatives.  Forecasts of population, income and
employment at the MTC Super district level at five year intervals to
2010 were obtained from the Association of Bay Area Governments'
Projections '92 series of demographic, economic and land-use
forecasts (MTC, 1992).

8.4  GENERAL AVIATION ALTERNATIVES EVALUATION RESULTS

Evaluation

     The General Aviation evaluation model consists of 17
spreadsheets (see Exhibits 8.1 through 8.17) displaying Existing
Conditions (1990) and High Forecast Conditions (2010) for each of
three system alternatives (No Build, Master Plans, and System
Optimization).  Each of the three system alternatives is shown on
four sheets which display the 24 primary general aviation airports
in the region (six airports per sheet).  In addition, Existing
Conditions are displayed on a series of four sheets.  Finally, the
1990 Existing Conditions and the three system alternatives are all
displayed in summary form on a single sheet for easy comparison. 
The spreadsheets display the following key elements of the
alternatives evaluation:

   1.   Total annual operations demand
   2.   Total annual operations capacity (annual service volume)
   3.   %  of operations at airports with obstructions
   4.   %  of operations at airports with towers

MTC Regional Airport System Plan Update
Chapter 8. General Aviation Alternatives Evaluation September 9, 1994

8.4.1   No Build

     Under the No Build alternative the existing airport system
would retain its existing airfield and landside capacity while
experiencing a high forecast 25 percent increase in total regional
based aircraft and a 33 percent increase in total regional
operations by the year 2010.  Under the low forecast, based aircraft
would actually decrease by 2.7 percent (this is the result of a
combination of attrition of current aircraft and no new demand),
while operations would grow by 6.4 percent.  Because the low growth
forecast falls well within even the system's current based aircraft
and operations capacity, the discussion contained herein focuses on
the high forecast.  As shown in the Summary of GA System
Alternatives, the overall system will accommodate both the total
based aircraft and operations in either the high or the low growth
forecast.  Total based aircraft demand will rise to 7,553 compared
to total regional capacity of 7,891.  Operations demand will grow to
just over 4 million annual operations, compared to annual capacity
of 6.6 million operations.

     While open tie-downs will be under utilized (capacity will
exceed demand by some 1,400 spaces), hangar space will be at a
premium, with demand exceeding supply by some 1,000 aircraft. 
Itinerant aircraft parking capacity (698 positions) would meet the
2010 forecast demand of 604 aircraft.  Clearly the most critical
issue in the future related to demand and capacity for any
alternative is how to deal with demand for hangar space.  'ne No
Build alternative would do nothing to address this demand at either
the regional or the local (airport by airport) level.

     With no significant shifts in regional demand or capacity, the
No Build alternative performs very much as the 1990 Existing
Conditions airport system when measured by where operations occur in
relation to airport obstructions, towers, ILS facilities, precision
approaches, airport lighting, and air carrier service.  Most
operations (95 percent) would occur at airports having approved ALUC
(Airport Land Use Commission) plans, and only 21 percent of all
operations would occur at airports having residential units inside
their 65 CNEL noise contour.  The No Build alternative would do
nothing to ease the conflict between air carrier and cargo activity
and general aviation activity at the region's congested air carrier
airports, with 36 percent of all GA operations occurring at these
airports.  In terms of safety issues, the No Build alternative also
does nothing to direct GA activity toward airports with control
towers, lighting, ILS (instrument landing system) installations, and
precision approaches, performing just as the 1990 Existing
Conditions system does.

     Several airports will experience operations demand levels
exceeding existing airfield capacity under the No Build alternative. 
These include Oakland, Palo Alto, and San Jose.  In addition,
Livermore would approach its annual operations capacity by the year
2010.  Similarly, without any additional aircraft storage capacity
or intervention in regional demand management, the following
airports would reach based aircraft saturation by the year 2010:
Cloverdale, Hayward, Healdsburg, Livermore, Nut Tree, Oakland,
Petaluma, Rio Vista, San Carlos, and San Jose.  This is not the
result of the region having insufficient capacity, but of specific
airports

MTC Regional Airport System Plan Update
Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

experiencing excess demand.  The key to this issue is the
inefficient distribution of capacity in relation to the location of
demand throughout the region.  The most critical element of this
capacity shortage, however, is in the need for hangars.  Airports at
which hangar demand will exceed supply would include: Cloverdale,
Concord, Hayward, Napa County, Nut Tree, Oakland, Palo Alto,
Parrett, Petaluma, Reid-Hillview, Rio Vista (old airport), San
Carlos, San Jose, and Sonoma County.  As of 1990 demand for hangar
space at Concord exceeded its hangar capacity.  Additional hangars
(80 spaces) are now under construction, which will reduce the
current shortage.  These are included in the No Build alternative. 
As hangar space at the new Byron airport is completed (this space is
currently under construction, and therefore included in the No Build
alternative), forecast future demand for hangar space in Contra
Costa County is expected to be met.

     Only two airports (Oakland and San Jose) are projected to have
65 CNEL noise contours which contain residential units.  Three other
airports have incompatible land uses in the vicinity which would be
affected by aircraft overflights and related single event noise. 
These are Reid-Hillview, Livermore, and Hamilton Field (if it were
re-opened for civilian GA use).  Operations at these five airports
represent 36 percent of the total operations forecast for the region
in 2010.

     There are 11 airports which border San Francisco Bay or have
wetland areas in close proximity which could be affected by airport
expansion.  These airports are Byron, Gnoss Field, Half Moon Bay,
Hamilton Field, Hayward, Livermore, Napa County, Oakland, Palo Alto,
San Carlos, and Sonoma County.  These bay and wetland areas may be
affected by airport improvement actions inherent in the system plan
alternatives.  With the No Build alternative, no specific new
development proposals are planned, and therefore, no impacts on the
bay or wetlands are anticipated.  The Master Plans and System
Optimization alternatives, on the other hand, could result in some
impacts to these resources.

8.4.2   Master Plans

     Between 1990 and 2010 the Master Plans alternative would
increase landside capacity by about 17 percent while experiencing a
25 percent (high) forecast increase in total regional based
aircraft.  Given that the region currently has excess based aircraft
capacity, the 17 percent increase will be sufficient to meet future
demand.  The key to meeting based aircraft demand, however, is in
providing enough hangar space for based aircraft.  While the No
Build alternative would result in a net future deficit of some 1,000
hangar spaces, the Master Plans alternative would provide a
significant increase in hangar capacity, bringing the deficit down
to only 150 spaces in the year 2010.  Of the 1,300 additional based
aircraft spaces provided, some 900 would be hangars, a direct
response to demand as expressed by the users.

MTC Regional Airport System Plan Update
Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

     On the airside, existing capacity exceeds demand at the
regional level by some 3.6 million annual operations.  This is more
than enough to accommodate the forecast 33 percent increase in total
regional operations by the year 2010.  As shown in the Summary of GA
System Alternatives, the overall system will accommodate both the
total based aircraft and operations in the high growth forecast. 
Total based aircraft demand will rise to 7,609, compared to total
regional planned capacity of 8,911. Operations demand will grow to
just over 4 million annual operations compared to annual capacity of
6.6 million operations.

     Near-term capacity improvements that are part of the airport
master plans alternative include apron expansion at Livermore; apron
expansion at Nut Tree; new aircraft hangars at Napa County; new T-
hangars at Palo Alto; new hangars at Rio Vista; new hangars at
Healdsburg; tie-downs and hangars at Byron as part of the initial
new airport development; and a new air traffic control tower at
South County.  In addition, numerous airfield taxiway, runway,
maintenance, lighting, safety, and operational improvements are
planned.  No significant airside capacity improvements are contained
in this alternative, as overall airfield capacity is not a major
issue.

     South County Airport's Master Plan and environmental approvals,
completed in 1982, call for expansion to accommodate 300 based
aircraft.  Beyond that level of development, additional planning and
environmental approvals would be needed.  In the longer term, South
County has enough property to accommodate up to a total of 600-800
based aircraft in conjunction with the reduction of GA at San Jose. 
This level of growth, however, is not included in the current
Airport Master Plan.  The proposed construction of a tower at South
County (included in the airport's capital improvement program) would
increase the airport's ability to accommodate this additional
traffic.

     While open tie-downs will be under utilized (capacity will
exceed demand by some 1,500 spaces), hangar space will be at a
premium, with demand exceeding supply by some 150 aircraft.  This is
a significant improvement over the No Build alternative, where
hangar demand would exceed capacity by some 1,500 spaces.  Itinerant
aircraft parking capacity (737 positions) would meet the 2010
forecast demand of 609 aircraft.

     With moderate shifts in regional demand and capacity when
compared to existing conditions and the No Build alternative, the
Master Plans alternative ranks differently in its level of
performance against the evaluation criteria.  With the shifting of a
moderate level of GA activity away from closer-in, restricted
airports (such as San Jose, Oakland, and Concord, this alternative
reduces the percentage of GA operations occurring at airports with
towers, ELS capability, and precision approaches.  On the other
hand, the Master Plans alternative removes a fairly significant
level of GA operations from airports that are primarily serving air
carrier passenger airlines and air cargo carriers.

     Most operations (97 percent)  would  occur  at  airports 
having  approved  ALUC  plans,  and  only 22 percent of all
operations would occur at airports  having  residential  units 
inside  their  65

Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

CNEL noise contour.  The Master Plans alternative would shift some
GA traffic away from air carrier airports, with the result that only
30 percent of all GA operations would occur at these airports.  This
compares to 36 percent for the No Build alternative.

     By effecting a better regional distribution of demand and
capacity, and by limiting demand at some congested airports, the
Master Plans alternative would result in airfield capacities being
adequate to meet operations demand at all airports except Palo Alto,
which would see annual operations demand of 316,540 compared to
annual airfield capacity of 310,000.

     Under the Master Plans alternative, the following airports
would reach based aircraft saturation by the year 2010: Concord, San
Carlos, and San Jose.  As with the No Build alternative, the most
critical element of this capacity shortage is in the need for
hangars.  Airports at which hangar demand will exceed supply would
include Concord and San Jose.

     Only two airports (Oakland and San Jose) are projected to have
65 CNEL noise contours which contain residential units.  Three other
airports have incompatible land uses in the vicinity which would be
affected by aircraft overflights and related single event noise. 
These are Reid-Hillview, Livermore, and Hamilton Field (if it were
re-opened for civilian GA use).  Operations at these five airports
represent 36 percent of the total operations forecast for the region
in 2010.

8.4.3   System Optimization

     This alternative envisages capacity expansion at a number of
the peripheral airports, as discussed in Section 8.2.3, and a
reduction in activity levels at Hayward and San Jose.  Even if the
development of peripheral airport capacity is adequate to ensure
enough capacity at a regional level for both the high and low growth
forecasts, the distribution of demand in the region may not fully
match the distribution of available capacity, and some airport
owners will find that they are unable to base their aircraft at
their airport.

     In order to assess the extent to which the airport system will
be unable to accommodate the preferred distribution of based
aircraft, the regional demand was allocated to airports using the
methodology discussed in Section 8.3.2, with the relative
"attractiveness" of each airport in the model adjusted to reflect
the facility changes anticipated under this alternative, but without
a capacity constraint at any of the airports.  The results of this
allocation for the high growth forecast are shown in Exhibit 8.13 to
8.16.

     With a few exceptions, the distribution of demand in the region
under this alternative does not change significantly from the no-
build alternative.  South County shows the largest gain, attracting
almost 200 more aircraft, while Livermore and Napa each attract
about 100 additional aircraft.  Oakland, Nut Tree, San Carlos, and
Sonoma County attract about 50 more aircraft each.  The assumed
changes at San Jose attract about 100 fewer aircraft.

MTC Regional Airport System Plan Update
Chapter 8: General Aviation Alternatives Evaluation September 9, 1994

     If the airports indicated in Section 8.2.3 are expanded to the
levels indicated in their master plans, there will be adequate
regional capacity to handle the low growth forecast., but a
shortfall of based aircraft capacity of some 350 spaces under the
high growth forecast.  While this is not a large number in
comparison to the total fleet, and could be fairly easily handled by
modest expansion of other airports (or further expansion of the
peripheral airports), the imbalance between local demand and
available capacity is more acute is some parts of the region.

     San Jose and Hayward both have significant shortfalls of based
aircraft capacity, almost 350 aircraft in the case of San Jose and
about 250 at Hayward, while Oakland has a capacity shortfall of
about 150 aircraft.  San Carlos has a shortfall of about 100
aircraft, some 25 of which could be handled by Palo Alto.  Reid-
Hillview and South County could absorb about an additional 275
aircraft between them, leaving about 550 aircraft that would have to
be displaced from the South Bay and shoreline airports (airports
along the Bay).

     Both Livermore and Concord also have based aircraft capacity
shortfalls, almost 200 aircraft at Livermore and a little over 100
at Concord.  However, there is adequate planned capacity at Byron to
absorb all but about 50 of these, if the owners would be willing to
relocate.

     Most of the region's spare capacity is in the north Bay, with a
significant capacity shortfall only at Nut Tree, which attracts
almost 100 more aircraft than its planned capacity.  Petaluma
attracts about 50 more aircraft than its planned capacity, but Gnoss
Field and the other southern Sonoma County airports can easily
handle this.  Napa County and Sonoma County airports have a planned
capacity in excess of 100 aircraft more than they would attract if
the other airports were unconstrained.

     This suggests that both Livermore and Nut Tree need to expand
beyond the levels envisaged in their master plans, in order to
accommodate the demand under this alternative.  Since the principal
unmet demand is in the South Bay, further expansion of the north Bay
airports would only meet the regional demand at great inconvenience
to airport owners.  If San Jose indeed reduces the number of based
aircraft to the level envisaged in this alternative, additional
growth in based aircraft will most likely occur at Oakland and
Hayward.  If aircraft operations are not to increase proportionally,
it will be critical to find ways to encourage those activities that
generate the most operations per based to relocate to the peripheral
airports.

FOCUS GROUP SUMMARY AND ANALYSIS


I.      INTRODUCTION

Background and Objectives

     The Metropolitan Transportation Commission has commissioned
Apogee Research, Inc. to conduct a policy review to lay the
groundwork for the upcoming 1990 Update of the Regional Air-port
System Plan for the nine-county San Francisco Bay Area.

     The ultimate goal of Apogee's effort is to outline specific
policy options that should be considered in the updated RAP.

     Apogee first reviewed the policies and goals specified in the
1980 RAP, characterized current aviation trends, and identified
policies and issues that might merit special attention during the
update process.

     In the second phase of this review, Apogee conducted a series
of "focus groups" and expert panel discussions with a wide range of
constituencies that have an interest in aviation and airport policy.

     These focus groups were designed to stimulate discussion and
generate information that would reveal the range and diversity of
viewpoints on critical issues facing the airport s%,stem in the
1990s.

     In the third and final phase, this information was added to the
policy review findings to help shape the specification of policy
options to be evaluated during the RAP update process.


Topics for Discussion

The initial policy review identified at least six  key  issues  that 
should  be  addressed  during the update process.  These topics and
issues were also incorporated in the focus group discussions to
gather input and feedback from a wide range of perspectives.  The
following were among the key topics and issues discussed:

   -    The level and quality of aviation service needed or desired 
        in the Bay Area in the 1990s, including flights,
        destinations, cost and competition.
        
   -    Anticipated demand and how to meet it, including the
        perceived costs and benefits of increasing or reallocating
        capacity within the airport system.


1





   -    How  growth  can  best  be  managed   or   accommodated, and  
        how   to   balance growth with environmental quality issues,
        including noise, air quality, land  use, and preservation of
        wetlands and the Bay.

   -    The current economic impact  of  the  airport  system,  the 
        possible  effects  of policy change, and how economic
        benefits could be maximized.

   -    The   relationship   between    airport    system   
        growth/needs    and    ground transportation, including
        airport access, traffic congestion, and public  transit.

   -    Development of the   General   Aviation   and   Reliever
        airports,  including anticipated demand, costs and  benefits,
        access, safety, land use,  noise  and other environmental
        concerns.

   -    How regional airport planning can be developed and  
        implemented more effectively in today's unregulated aviation
        environment.

     The focus groups were designed to gather input on these
policies and issues from the broad range of constituencies that have
an interest in aviation and the airport system.  These discussions
were also expected to generate new ideas -- concerns that may have
previously been overlooked or suggestions for new policies and
solutions.

Composition of the Focus Groups

     To reflect the broad range of constituencies affected by
airport system policy, separate focus group discussions were
conducted with each of the following groups:

   A.   Management and other authorities from airports within the 
        system, including the five air carrier airports, general
        aviation airports and military facilities (Group 1)

   B.   Area business leaders, including both frequent and non-
        frequent flyers and airport users (Group 8).

   C.   Representatives from the airlines  using the airport system,
        including international and domestic air carriers, regional
        airlines, commuter, charter, and freight (Group 9).

   D.   Local  and  regional  government   officials,   including   
        representatives   from regulatory agencies and communities 
        adjacent  to  the  region's  five  commercial airports (Group
        2).

   E.   Environmental interest groups and environmental  staff  from 
        local  airports  and communities (Group 6).

2





   F.   Pilots who  use  airports  in  the  nine-county  region,
        including  commercial passenger and cargo, military, non-
        commercial general  aviation  and  corporate jet pilots
        (Group 5).

   G.   Bay Area frequent flyers who use the regional airport
        system, including  travel for business and other reasons
        (Group 3).

   H.   Area residents who live  near  a  major  commercial  airport 
        (SFO),  including both frequent and non-frequent flyers and
        users of SFO and  other  airports  in the region (Group 4).

   I.   Frequent flyers and residents in the San Jose and  South  Bay 
        area  who  could not be represented in the above two groups
        because  of  geographic  constraints (Group 7).

     Every effort was made to ensure that participants were drawn
from the widest possible range of perspectives, and that broad
geographic representation was provided within each group.  But
practical limitations on the participants (an optimum of 8-12) may
have inevitably resulted in the exclusion of one party or another. 
In other cases, individuals who were invited were unable to attend.

     An attempt was also made to cover the full range of critical
issues and topics identified in the earlier policy review.  However,
the emphasis on these topics varied from discussion to discussion,
depending on the interests and background of the participants.

Research Method and Procedures

     Focus groups were selected as the method most appropriate to
help achieve the goals of this review.  When designed and conducted
by experienced professionals, focus groups can provide a rich source
of in-depth, qualitative information.  While the results cannot be
quantified or projected to a larger population, focus groups are
most effective in revealing the full range and diversity of
concerns, perspectives and attitudes on a particular topic under
investigation.

     For this reason, focus groups are often used to provide the
groundwork for further quantitative study, by defining the bounds or
parameters of a study and identifying the precise issues that
warrant further exploration.  They are also useful in designing
survey questionnaires to ensure that relevant questions and response
categories are included and are phrased in the common language of
potential respondents.  Focus groups also provide an excellent forum
for observing the way that people think about issues and react to
specific arguments or propositions.

3


     Focus groups can be conducted with consumers and members of the
general public as well as specific target populations, including
authorities and experts on a particular topic.  The latter are often
called "expert panel" discussions.

     The success of a focus group depends largely on (1) careful
selection and recruiting of participants, and (2) effective
moderating that stimulates and guides discussion in a neutral,
probing manner. Expert panel discussions also require that the
moderator have a background in the topic of interest, in addition to
the skills necessary to effectively moderate less technical focus
groups.

     For this purposes of this study, individual focus groups were
conducted with each of the nine target groups.  Between 12 and 16
individuals were invited to participate in each of the individual
sessions.  The nine focus groups were held between Wednesday,
November 7 and Friday, November 9 in several locations.  "Expert
panel" sessions were scheduled for the morning and afternoon, with
frequent flyers and residents meeting in the evening.

     Most of the expert panel discussions were held at the
MetroCenter in Oakland.  This included discussions with "Government
and Civic Leaders" and "Airport Management" on November 7 and "Area
Business Leaders" and "Airline Representatives" on November 9. The
discussions with "Pilots" and "Environmental Activists and
Authorities" were held on November 8 at the Port of Oakland because
appropriate space was not available at the MetroCenter.

     San Jose residents and frequent flyers met at a facility
operated by Nichols Research in Sunnyvale.  San Francisco area
residents and frequent flyers met at a facility operated by Ecker &
Associates in South San Francisco.

     Rosters of participants in the "expert panels" were developed
from lists of known officials. experts and authorities.  These
individuals were then contacted by telephone and mailed a
confirmation letter along with an outline of topics to be discussed. 
A complete list of actual participants is provided in Appendix A.

     Local residents and frequent flyers were recruited
systematically by telephone from a random sample of Bay Area
residents.

     Participants were first qualified to ensure that they lived in
specific communities adjacent to particular airports or had flown
six or more times in the past 12 months.  Participation also
required that they neither work in the aviation, airline or market
research industry nor have participated in a focus group in the past
six months.

     Screening questions were  also  used  to  ensure  that  each 
group  reflected  the  population's diversity on age, sex, race, 
income  and  other  demographic  characteristics.  Frequent  flyers
and community residents were paid a monetary incentive for
participating.

     Each focus group and expert panel session lasted between 90
minutes and 2 hours.  These discussions were fairly informal, with
experienced moderators from Apogee raising issues with open-ended
questions and then stimulating and guiding the discussion in a
neutral manner.

The moderators were:

   -    Dr. Richard Mudge, President of Apogee Research, Inc. and a 
        national authority on economics, public works finance and
        aviation policy.

   -    Matt Hardison, Vice President of Apogee Research,
        responsible for the firm's airport and aviation research and
        consulting practice.

   -    Dr. Robert Hurd, President of Apogee Market Strategies, the 
        market research and polling arm of Apogee Research.


     All three have considerable experience conducting focus groups
for airport planning.  Drs.  Hurd and Mudge are co-authors of a
Market Research Handbook for Transportation Officials, recently
published by an arm of the National Academy of Sciences to help
educate public agencies on how market research, opinion surveys and
focus groups can be used to improve transportation planning,
programs and communication efforts.

     Most sessions were (audio) tape recorded, and some were
videotaped as well.  Participants in the frequent flyer and airport
resident groups provided their informed consent to allow the
discussions to be videotaped and observed through a two-way mirror
at the focus group facility.  This is a standard industry practice
that allows for more thorough and accurate analysis of the results.

     Detailed, narrative summaries for each of the nine focus groups
are provided on the following pages.

II.  NARRATIVE SUMMARIES OF FOCUS GROUPS


6


A. AIRPORT MANAGEMENT (Group 1)



     The series of focus groups was kicked off by an in-depth
discussion among more than a dozen airport operators and managers,
including representatives from the air carrier airports, military
facilities and General Aviation and reliever airports throughout the
region.  These managers also included representatives from local and
county governments responsible for airport and aviation issues.

     These airport operators and managers agreed that planning is
especially important now because capacity is becoming constrained
and demand is expected to increase.  They believe that coordinated
regional planning is the key to increasing system capacity while
also avoiding the negative impacts of expansion.

     The central concern among the participants was management --
how airports can effectively meet increased demand in a system
characterized by shrinking airspace and growing public insistence
that environmental. impacts -- noise, degradation of wetlands, and
traffic congestion -- be minimized.

Demand and Capacity,

     These managers agreed that growth is being driven by powerful
market forces.  They believe that increased demand is inevitable,
and that they need to meet -- and even stimulate -- this demand.

     The airports and the airport system need to do a better job, in
their view, of anticipating these market forces and minimizing their
negative impacts.  Rather than trying to change or fight these
forces, the managers said the airports and airport system must be
better prepared to accommodate and adjust to market trends.
     Some said the system cannot meet existing levels of demand,
much less the increases that are projected.

     One manager, however, was more optimistic about the ability to
accommodate increased system demand, particularly at SFO.  The
airport served 31 million passengers last year, he said, and
forecasts project that demand will soon reach 51 million at SFO and
75 million passengers throughout the region.  Despite charges that
SFO is near capacity, he explained that the airport could
theoretically handle this increase demand because those 31 million
passengers flew out on 51 million seats.  He suggested that load
factors are increasing, although he conceded "not by 100 percent."

     There was considerable discussion of the flight tracks used by
SFO and OAK.  Most of the operators and managers concluded they need
more airspace and agreed that the primary

7

constraint is environmental concerns.  One participant also noted
that airspace is especially shrinking for the military, as the "big
three" airports expand.

     They agreed the biggest increases in air system demand have
come from international flights (primarily at SFO) and from air
cargo traffic.  They noted that manufacturing has become a worldwide
process, leading to increased air cargo operations, especially at
OAK and Sea Transport.

     As domestic and international air traffic increases at SFO, its
ability to accommodate air cargo demands has become more
constrained.  As a result, these managers believe air cargo is being
pushed out to other airports and becoming more decentralized.  While
this represents a loss of business for SFO, SJC in San Jose hopes it
will become their gain.  San Jose is also encouraging international
service.

     The managers indicated that adequate on-site facilities were a
key issue in continuing to meet the needs of air cargo at the
region's airports.  Landside access was discussed as a critical
component for air cargo operations.

     The managers foresee a growing role for reliever airports,
particularly Buchanan Field, in accommodating system-wide demand. 
They agreed the system has a real need to preserve these facilities,
but provided few concrete suggestions on how the individual airports
might contribute to the development of the reliever airports.

     There were also considerable interest in promoting the
development and use of helipads to off-load some of this demand.

General Aviation and Reliever Airports

     There seemed to be general recognition among these managers of
the role that reliever and General Aviation airports play, or could
play, in accommodating system-wide demand.

     Managers from the smaller GA and reliever airports were most
enthusiastic about their potential contribution, but expressed
strong concern about "unilateral" local action that threatened their
very existence.  Local governments are under increased pressure to
shut down GA airports while General Aviation representatives
perceive they are also being pushed out" of the larger airports.

     Managers from the larger airports conceded this was a problem,
but seemed generally reluctant to accept responsibility or a more
active role in solving it.  In fact, one manager proclaimed that
General Aviation itself was "dead" and "not coming back."

     Nevertheless, the managers seemed to agree the system as a
whole has a strong interest in preserving these facilities to meet
future increases in demand.

     There was considerable concern about the disposition of
military facilities and the need to protect land around particular
airports (e.g. Napa) that might need to be developed in the future. 
They recognize existing military and GA airports as assets that
would be difficult to replace and should not be wasted.

Financing

     While the three major commercial airports are financially
sound, the remaining airports are largely incapable of adding to
their capacity independently because they rely on below-cost user
fees and local government contributions to pay for capital costs.

     For this reason, several managers recommended that the system-
wide plan include some form of integrated financial support from the
major airports.  Others responded that, while the airlines have
"deep pockets," it is unlawful to use airport money for off-airport
improvements.

     The managers also expressed concern about public investment in
infrastructure in the region.  To be effective, an airport system
must be supported by good highways, public transit and a wide range
of public services including good housing, education and training. 
The managers discussed the lack of funding for infrastructure and
expressed concern about its impact on both the airport system and
the region's economic productivity and vitality.

     They suggested again that reliever airports were particularly
under funded, and pointed out that MTC's share of state budgets has
been declining.  Interest was expressed in the possibilities offered
by PFCS.  And the managers agreed that it is important for MTC to
help the region get a larger share of AIP funds.

Environmental Issues and Noise

     These managers recognize environmental concerns as the primary
constraint on their operations and the ability to meet future
demand.  Perhaps for this reason, they seemed to accept
responsibility for minimizing the environmental impact on wetlands,
noise, traffic in their efforts to accommodate market demand.

     But they also noted that some social costs were unavoidable and
should be balanced against the economic and other benefits generated
by the airports in the region.

     Airport noise dominated the discussion of environmental issues. 
The operators and managers offered several possible solutions which
generated considerable discussion:

Land Use Planning

     The managers agreed that better control of land use around the
airports will be essential for resolving noise and other
environmental issues.  They view the Airport Land Use

9


Commission as a step in the right direction, but said it has not yet
achieved success because the commission has no real "teeth." The
airport operators and managers felt the RAP and the RAP planning
process might be an appropriate forum for addressing these issues.

Quieter Aircraft

     The managers noted that the new Stage III aircraft are much
quieter and that there are a number of things they can do
operationally to further reduce noise.  Nonetheless, these aircraft
are not being used for air cargo which often flies at night.  Nor
are these aircraft appropriate for military use.

     One participant noted that the military has been unsuccessful
at curbing noise for this very reason, and predicted that as
residential growth continues unchecked around old bases, people will
become increasingly more sensitive to noise.

Measured vs. Perceived Noise

     There was also concern that quieter aircraft may not solve the
problem.  They agreed that there is an important difference between
actual "statutory noise" that is measured and the noise that is
perceived by residents, especially on overflights.

Fewer Flights

     There was some hope that a solution might come with the advent
of larger aircraft, requiring fewer flights and allowing these
flights to be spread out over time.  The managers agreed the system
would benefit if it could find ways to facilitate and encourage this
distribution of flights.  But they noted there were significant
limitations to the system ability to do so.

     It was apparent that OAK, among other airports, is under
pressure to increase the choices available to its customers.  As
with most airports, they need to find a way to get the best use
of an expensive capital facility.  Limiting flights and consumer
choice makes that task more difficult.

     The managers also expect, on one hand, that there may only be a
few large carriers competing in their markets in the near future. 
This would have the effect of reducing both traffic as well as
"peaking." But they said, on the other hand, that hubbing generates
peaks even when the number of carriers are limited.

     "If we limit the number of flights," one manager concluded,
"the market will take care of the rest."

10

Peak Pricing

     The managers also agreed that peak pricing would not be
effective because the terminal costs (over which the managers have
control) represents only a small percentage of the airlines
operating costs.

     They also noted that the airports are part of a national system
over which they have little influence and certainly no direct
control.  And as one manager put it, "If we solve the peak problem
here, it will only make it worse somewhere else."

Costs of Not Expanding

     The costs of not expanding the airport system were also
discussed at length.  Not only would limits on air traffic have a
negative economic impact on the region by raising the cost of living
and constraining job growth, but it would also increase the amount
of truck traffic and congestion if people and products cannot be
moved by air.

Regional Planning and Coordination

     Late in the discussion, the participants were asked how the
Regional Airport System Plan (RAP) might be improved and made more
useful to them.

     It was clear from the ensuing discussion, however, that these
operators and managers were not generally familiar with the 1980
plan, and that little conscious effort had been made lo comply with
its policies.  Nor has the 1980 RAP been used in planning at the
individual airports.  Only SFO appeared to use the RAP, and then
only for general ideas.

     Despite this lack of awareness, the operators and managers
agreed that coordinated planning was necessary and desirable.  They
noted that none of the major air carrier airports currently
coordinates development plans with each other or with the reliever
airports.  This lack of coordination, they said, could create
problems that affect system capacity and efficiency

     As long as the three airports seek their own niches in the
market, extensive coordination may not be necessary.  But not all of
the managers were convinced that SFO, OAK and SJC have established
such distinct market niches that they no longer compete with one
another.  A manager from San Jose, for example, said that although
SFO dominates the international market, it is not the only airport
providing international service.  There's "lots of overlap," he
said.

     Better,coordination and regional planning could help increase
system efficiency and capacity and reduce congestion.  This may be
even more true for issues other than competition or duplication
between the three major commercial airports.

11





     For example, the managers perceive that the city of San Jose is
currently forcing GA traffic out of SJC while the county is
simultaneously trying to close Reid-Hillview, a nearby reliever
airport.

     The participants suggested the next RAP begin with a careful
and comprehensive examination of each airport and community's Master
Plans.

The Role of MTC

     A clear example of the need for effective, coordinated planning
was provided by a lengthy discussion about the need and demand for
increased commuter service, especially in the Napa and Livermore
areas.  During this discussion, the managers also suggested a number
of ways that MTC could contribute significantly to the solution of
this and other problems in the region.

     The managers suggested that MTC conduct market research to
promote airline service in the North Bay area.  They noted that
Livermore is the only community in this area of high growth with an
airport, and that commuters could be drawn down from Solano County. 
The managers believe this air service would benefit the entire
region, but perceive the local community opposes such airport
operations.

     A participant from San Francisco said that SFO has had some
success with airport community round tables.  While most of the
managers agreed this could be an effective approach, they said the
problem is not simply one of community relations.  The critical
issue, in their minds, is how to share the benefits of increased
activity or expansion at a local airport.  And this is where they
see a role for an agency like MTC.

     From their point of view, such decisions are beyond the
abilities or responsibilities of the individual airports.  As one
manager said, "Let the politicians decide -- that's there job."

     One manager noted that the values of homes near airports are
generally depressed, and suggested that taxes for these people might
be -reduced as a form of compensation or recognition of the negative
impact noise and other dis-benefits.

     Another suggested that noise be spread out according to a
formula based on economic benefits -- areas that receive a greater
proportion of the economic benefits would be required to shoulder a
greater burden or share of noise.

     The managers believe that most citizens accept their airports,
and simply don't want any existing problems to get worse.  What is
needed, they said, is some way to educate the public.about the
constraints under which the airports operate and the benefits these
operations generate for local residents.


12

     They also suggested that MTC conduct a market research survey
of the region to determine precisely where both market demand and
political support exists for air service and airport development. 
This survey would provide valuable information not available
elsewhere, and could facilitate the decision-making processes of
both the airports and local communities.

     Local community leaders need to know how their constituents are
using the airport system, they said, and this knowledge might
provide the political support necessary for effective coordination
and policy implementation within the system.

     These discussions suggested strong support for an expanded
research and public education role for MTC.

Improving the RAP

     There was considerable discussion about how the 1980 RAP itself
could be improved, or what features would be needed in an effective
and useful regional airport system plan.  Specific suggestions for
improvement included: (1) making the goals more realistic and
attainable, (2) marketing the updated RAP more aggressively to
airport managers, public agencies and the public, and (3) making the
document less technical and more understandable.

Realistic Goals

     The managers suggested the goals of the updated RAP be made
more realistic and attainable.  They noted that some key decisions
were beyond the region's control, including "boardroom" decisions
like American Airlines move to make San Jose a hub.  Many other
developments will be determined by the market.

     They also recommended that these goals be accompanied by
specific strategies for implementation.  Again the suggestion was
that these goals and plans recognize the preeminence of market
forces -- and seek to accommodate or adjust to market forces,
instead of trying to fight them in vain.

Public Education

     Another suggestion was that the updated RAP place a greater
emphasis on public communication and information -- making the RAP
more accessible by (1) improving distribution and promotion of the
document itself and (2) making it less technical and easier to read
for the general public.

     There was particularly strong support for an update that would
be effective in communicating the benefits and contributions (if the
airport system to region, and explaining the complexity of the
problems faced by airport managers and the constraints under which
airports now operate.

13


     For example, it was suggested that the next RAP might include a
simplified explanation of flight tracks, in part to help educate
local residents about the limited options available for routing
aircraft.

     They also suggested the update include a lay person's
explanation of FAA regulations and the airport's unavoidable links
to the network of other airports nationwide.  They believe this
would contribute significantly to public understanding and a more
constructive approach to resolving problems in the region.

     The challenges of educating the public about economic benefits
were also raised.  Business people might accept the results of
economic analyses, but many residents are not familiar with these
techniques and are less likely to believe in such abstractions and
conclusions.  Clearly, new and more effective methods need to be
found, and such efforts might fall within the role and
responsibilities of MTC.

B. AREA BUSINESS LEADERS (Group 8)


     Although turnout was lowest for this Friday morning group, the
session allowed for more thorough and detailed discussions with the
individual participants -- shedding additional light on the some of
the perspectives and leading concerns within the Bay Area business
community.

     The participants agreed they currently receive good service
from the airport system, but also expressed concern about the future
-- particularly about insufficient or inadequate GA and reliever
airports.

     Some cited evidence that the system is already overcrowded --
flights are often full, hard to get or overbooked to the point where
"bumping" has become a problem.  They believe that the quality of
aviation service plays a critical role in economic development and
productivity.


     The most critical issues, in their view, include accommodating
increased demand in the future and ground access -- getting people
and cargo to and from the airports more effectively and efficiently.

Growth and Capacity

     The participants see the Bay Area as a vital, growing community
offering considerable economic potential and opportunity.  They
agreed that the airport system needs to accommodate this growth as
well as the increased demand for air service.

     And they believe that through effective planning a proper
balance can be reached between economic concerns and the
environment.

     But these business people also expressed concern about the
apparent proliferation of disparate and potentially competing
planning efforts.  Without interaction between the various
organizations, these efforts might ultimately prove ineffective,
they said.

     The participants see the growth of international service at SFO
and the expansion of SJC as positive signs, and strongly support the
expansion of OAK. They believe that international service has
contributed greatly to economic development, but better flights to
Europe are also needed.

     They believe the three major airports serve somewhat distinct
market niches, and should continue to do so.  But they also believe
that even better market segmentation would result in better service
and reduced congestion.  They also support moving cargo operations
and other activities to outlying airports.

15

 

    Public attitudes toward growth, they noted, have been cyclical
over the long term.  Some participants expressed concern that
current "anti-growth" feelings have constrained the region's
competitiveness and its ability to take advantage of economic
opportunities, particularly those in the Pacific Rim.

     The leaders also noted that growth tends to skip over areas
that do not want to grow, creating a "sprawl" that puts an even
greater strain on the system.  Sacramento and the interior of the
state were cited as prime examples of this tendency.

     These participants, however, believe that transportation policy
could be an effective tool for controlling or managing growth.

Accommodating Future Demand

     One participant suggested that something "bold and innovative"
was required -- the construction of a very large airport in an
outlying area with ground access provided by high speed surface
transportation.

     A very different consensus, however, quickly emerged from the
group.  The region's top transportation priority, they said, should
be to make the existing, infrastructure system work better.    There
was particular emphasis on the need to improve the integration of
transportation services throughout the system.

     The participants support the expansion of San Jose Airport and
OAK.  They said that while it is now more convenient to use SFO,
they would prefer to fly out of OAK more often.  They indicated that
access was a deciding factor, along with the timing and destinations
of flights.  They seemed to feel that demand could be re-allocated
from SFO to OAK if access was improved and the desired flights were
available.

     They also see the GA and reliever airports as assets that will
be of even greater value in the future when it comes time to
accommodate increased demand.  Participants suggested that all cargo
might be shipped out of a single airport, preferably an existing
facility like Moffett Field.  They recognized that while moving
cargo operations may not provide much relief during the day, they
certainly require considerable facility space that could be used in
other ways.

     They also noted that airport expansion is often desired to
reduce noise and other environmental problems, and not to meet
demand.

Ground Transportation and Access

     These business leaders view ground access as one of the most
important issues facing the aviation and transportation  system. 
There is strong demand for improvements that would

16




connect the mass transit system with the airports, and the airports
with each other.  The participants said the area needs a better
feeder system for getting people to BART, that it wasn't working as
it should.

     They also complained that BART was, at times, crowded and
unsafe.  Other comments suggested increased support for access
charges and true user fees, such as tolls.  The participants were
concerned that people are not paying their "fair share" and seemed
opposed to subsidies for transportation choices when other
alternatives are available.

     The participants also see rapid transit as one way to avoid
growth at SFO.  And while they desire better access to SFO, they
also believe that improvements to BART would make it more convenient
to use other airports like OAK that they truly prefer.

     Throughout these discussions were calls for "better
integration" and suggestions this be the top priority for planning. 
As one person put it, "The pieces are there, now we just need to
make them work together better."

     There was interest, for example, in linking the major airports
so passengers could depart and return to different airports.  There
was also a strong emphasis on "intermodalism" not only for
travellers, but also for cargo.  Participants saw the latter issue
as becoming critical for the region's economy over time.

Improving the RAP and Other Issues

     These business leaders suggested that MTC and the RAP could
make a significant contribution to improving the region's airport
system by focusing on public education and information.  They were
confident that a better informed public would mandate necessary,
improvements and provide the political support necessary for greater
policy coordination and cooperation.

     They also recommended that planning efforts take into account
the tremendous costs that will be incurred by the clean up of toxic
and other hazardous waste.

C. AIRLINE REPRESENTATIVES (Group 9)


     One of the focus group discussions brought together
representatives from airlines serving the Bay Area Regional Airport
System, including international and domestic air carriers, regional
airlines, commuter, charter and freight air services.

     These airline representatives agreed that the region's aviation
system is already overcrowded and not meeting current needs or
demand.  They cited problems with access, air traffic and congestion
at the gates, particularly at SFO.  An airline representative from
SFO, however, was quick to suggest that SFO is not yet at capacity
overall, just during peak periods.

     Nevertheless, they agreed that demand for air service will
continue to grow, and the system will grow to meet that demand. 
There appeared to be considerable support for developing smaller,
reliever airports, particularly to improve air service for commuters
and corporate travel.

     The representative were divided, however, on the merits of     
developing an expanded "feeder" or "hub and spoke" system into the
major air carrier airports versus increased point-to-point service
among smaller communities not currently served by the airlines.

Capacity and Growth

     The airline representatives believe the region will continue to
grow, and require increased activity at the airports in the system. 
They expect that the individual airports and air carriers will also
grow, along with a wide range of support services.         An
airline representative said it will be necessary to build more
accommodating terminals, for example.

     Not planning for growth would be unrealistic because it would
result in a loss of business, then, explained, suggesting instead
that the question be what kind of growth does the region want and
where does it want to channel this growth?

     The participants said the region's population is moving north,
and the system needs to either build new airports or improve
existing facilities there.  Once again, there was a strong
preference for preserving and converting existing facilities such as
Travis Air Force Base in the North Bay area.  They noted this area
of high growth is served only by Nut Tree Airport, and that
commuters must now drive to Sacramento or the Bay Area to get
commercial air service.

     This and other markets would be better served, they suggested,
if the regional system supported airport development -- either
creating a hub and spoke network of smaller "feeder airports" into
the major commercial airports, or promoting more frequent point-to-
point air service between smaller communities not currently served
by the airlines.

18





     At least one representative from the three air carrier airports
favored the "feeder" airport concept.  He explained that neither SFO
nor any other airport can operate a successful hub without a strong
local market.  But the local market in San Francisco alone is not
sufficient, he said, to provide the kind of frequency that consumers
have come to expect for flights to Los Angeles, Tokyo or other major
destinations.

     He estimated that 50 percent of the air traffic between Los
Angeles and San Francisco is neither L.A. nor San Francisco traffic,
but rather East Coast and Pacific connections.  Offering O'Hare
airport in Chicago as a model, he said that the development of a
strong feeder system would benefit everyone involved.

     The last RAP, he added, overlooked the need for "hubs and
spokes" and failed to account for the increased number of
destinations and more frequent flights they would offer.  Others
suggested that commuters and local business travelers would prefer
point-to-point air service, rather than be required to accept the
inconvenience of making connections in a hub and spoke system.

General Aviation and Reliever Airports

     Again participants proclaimed that General Aviation is "here to
stay," but should be controlled.  They were also careful to
distinguish between "true general aviation" and the business
owner/operator or corporate jet charter.

     These airline representatives expect that GA and corporate jets
will be eliminated by SFO at some point in time, and some expressed
concern that it might also be eliminated from OAK and San Jose. 
This would be very problematic, they suggested, because then
reasonable access would be denied to downtown San Francisco.

     Currently, the corporate jet community feels well served by the
Oakland airport, but future plans at OAK threaten that use.  There
was considerable Discussion of methods to mitigate noise at OAK
without inhibiting private corporate and business flights, including
the suggestion that planes takeoff and land on different fields,
North and South.

     Many of the representatives suspect there is a real demand for
commuter/charter service out of the smaller airports.  Many
commuters and other people, they said, would rather not have to go
to the larger airports when they fly.  Market forces, population
growth in outlying areas, and increased congestion will all create
growing pressure for commuters to switch from ground to air
transportation.

     Some representatives advocated  the  development  of  a 
stronger  feeder  system  that  would enable-local commuters to
board their flights at nearby GA and  reliever  airports, changing
planes at SFO or one of the other major commercial airports in the
region.


19




    They suggested that market research is needed to evaluate this
potential market, assess consumer demand and determine how it might
best be satisfied.

     They also indicated that convenience, reliability and
confidence would be the key issues for the success of such a system. 
One representative praised American Eagle for making "great strides"
in recent years building consumer confidence with better aircraft
and pilots.

     Developing this market would also require the presence of a
commercial airline, so that the smaller airports could qualify for
FAA funding.  They observed, however, that there are "big
differences" in security at the GA airports which need to be
addressed.

Ground Transportation and Access

     As might be expected, the airline representatives questioned
the viability and demand for a high speed rail link between the Bay
Area and Los Angeles.  Commuters and business travelers as a whole
will always prefer air travel, they said, because it is faster and
more convenient.  And while rapid transit might be desirable, some
suggested it will always be difficult to "get Californians out of
their cars."

     They also agreed that traffic congestion and ground access are
already serious problems at SFO, and growing worse at OAK, SJC and
even Concord airports.  Rapid transit to tile airports is needed,
some said, because current limitations on access represent a real
constraint on growth, particularly at SFO.

     There was considerable discussion about the merits of bringing
the BART line directive into the SFO airport.  Some expressed
interest in the idea.  But others suggested that current plans would
leave passengers in the parking garage, a location that would not be
convenient to any of the gates.  The preferred alternative was to
develop a monorail that would run from the BART station off-site to
each of the gates or terminals.

     Some hoped that it might be possible to check baggage at the
off-site BART station.  But the representatives were generally
skeptical of the "remote terminal" concept, saving that it is simply
not feasible to segregate the baggage.  Some suggested that
automation might solve the problem, but others remained leery.

Noise, Zoning and Safety

     The airline representatives said they are already doing a lot
to minimize noise, and perceive that it is a "chicken or the egg"
problem -- insisting that responsibility be shared by the people who
chose to live near airports and by communities that failed to zone
against residential development there.

     These representatives believe that noise will continue to be a
persistent problem, but one that could be prevented from spreading
through better planning and zoning.  They called for

20





better cooperation between airport managers and communities to
mitigate future problems created by new community development.

     They also recommended that noise restrictions be updated and
based on measured noise levels that were more "realistic." They were
strongly opposed to current restrictions that are based on aircraft
weight or type, instead of actual decibel levels.

     Finally, these representatives expressed a belief that some of
the complaints about aircraft noise actually reflect public concerns
about safety.  They suspect that when people hear planes near their
homes, it reminds them of possible safety threats.

     They praised the industry for its safety record, and lamented
that the public cannot see the increased safety measures that have
been implemented.  Nevertheless, they agreed the system is not
infallible, and there will be accidents that capture the public's
attention.

Improving the RAP

     The airline representatives were not familiar with the 1980
RAP.  But they suggested that for any regional planning to be
effective, the airports and local communities would have to "buy in"
to the plan.  This would only be possible if they were afforded real
opportunities to become more involved and contribute significantly
to the actual planning process.

     They also suggested that greater coordination may be possible,
as the airports themselves seem to be more interested in working
with the airlines in recent years.

D. GOVERNMENT AND CIVIC LEADERS (Group 2)

     The participants in this group were primarily government
managers and policy-makers, and included representatives from
regulatory authorities, civic groups and communities adjacent to the
region's five commercial airports.

     These officials generally agreed that increased demand could be
expected in the coming years and that the system and its components
would grow in an effort to meet that demand.  They focused their
discussion on the question of how this growth could be controlled
and coordinated to minimize its most negative effects such as noise,
congestion, and safety problems.

     But there was also considerable discussion of the effectiveness
of various means or methods that might be available for restricting
airport growth.

Accommodating Increased Demand

     There was general agreement that the current aviation system is
approaching capacity, and that demand will continue to increase. 
Many officials expressed a need or desire to find ways to increase
system capacity and meet future demand, while others focused on how
airport expansion could be avoided or restricted.

Better Coordination

     Several officials suggested that increased capacity could be
achieve through better coordination among the airports. This
discussion began with a suggestion that the independence of the
three major commercial airports leads to "unnecessary duplication."
Several participants said the system's top priority should be "more
efficient use of scarce resources," rather than expanding individual
airports.

     However, they said it would not be necessary to impose a single
management authority over these individual airports as long as a
unique role could be established for each.

     Nevertheless, most officials expect continued competition among
the airports because "there will always be a demand for
convenience." The officials seemed to agree that the airport system
required greater coordination among airports and with local
government and planning authorities.

Alternative Modes

Other officials hoped to off-load increased  demand  through  the 
development  and  use  of alternative modes of transportation.  One
official noted that much of the air traffic at  LAX

22


in Los Angeles is travel to the Bay Area, indicating that there is a
potential market for rail or high-speed ground transportation.

     This suggestion generated considerable enthusiasm, along with
reservations about possible cost, feasibility, right of way,
environmental impacts and the length of time required for
development and construction.

     There was also considerable interest in the possible
development of a "high-speed bus' system between the Bay Area and
Los Angeles.  And helicopters were mentioned again as a possible way
to off-load some of this demand.

Developing Reliever Airports

     There was considerable discussion of the advantages of
preserving the GA and reliever airports as assets that might be
needed in the future.  Most frequently mentioned was Hamilton Field.

     These officials seemed to recognize, at least in the abstract,
the role that reliever airports could play in helping the airport
system accommodate increased demand.

     They perceive that the air carrier airports, including OAK, are
currently driving off General Aviation to accommodate increases in
commercial traffic, particularly air cargo and international
flights.  At the same time, these officials are aware that many of
the GA and reliever airports face opposition from their local
communities.

     They were unable, however, to agree on any concrete solutions. 
While some expressed a preference for developing existing sites over
new construction, others seemed to hope that neither would be
necessary.  Common concerns about airport development included
safety, noise, land use and financing.

     One participant argued the system's GA and reliever airports
should be preserved and developed because area bridges are fragile
and the region needs an air component for emergency relief.

Other Restrictions

     There was also some discussion of methods available to
constrain or restrict growth.  It was noted that expansion is
currently allowed only if it reduces environmental impacts.  One
participant suggest that air quality measures might also be used as
a check on growth.  Another mentioned financing as an effective
constraint.

     Zoning for land use was described as "self-defeating" because
it simply raises property values.

23


     The participants recognized the interconnections among each of
these issues or approaches.  One official, for example, noted that
if air travel is restricted, it will simply add to other problems --
regardless of the means by which those restrictions are achieved.

     Noise complaints are perhaps the most persistent problem
associated with airport operations facing these officials.

     They noted that the trend toward "hubbing" invariably leads to
increased noise.  Some expressed hope that noise would be reduced
with the advent of larger aircraft requiring fewer flights.

     But another participant suggested the market is "moving in the
direction" -- toward smaller planes and more frequent flights.  For
that reason, he concluded, regulation will continue to be necessary.

     The session also included a representative from a citizen's
group concerned about airport noise.  She claimed that most people
do not fly, and that the quality of life for residents near airports
"quickly deteriorates" with increased operations.

     Taking off over the water, she explained, is not an adequate
solution because the planes must eventually turn over residences
somewhere.

     Instead, she recommended that the region promote the use of
trains and other alternatives.  She also suggested there might be
increased demand for re-regulation of the airline industry, giving
the government more authority to limit airport operations and the
noise associated with it.

Ground Transportation and Access

     Much of this discussion centered on the desirability of
improving intermodal connections within the region's transportation
system overall.

     These officials consider ground access to be a crucial
component of the aviation system.  They were divided, however, over
the merits of bringing a BART line directly into SFO versus
developing a monorail that would run from the current off-site BART
station off-site to the terminals and their gates.

     As one official put it, "Are you trying to get people to the
airport or to the planes?"

     There was also some interest in a "remote terminal" concept for
the future.  Another official noted the importance of the landside
time constraint, and expressed interest in tunneling under the Bay.

24

Improving the RAP

     One participant complained there currently is no recourse or
accountability for airport problems -- no single authority exists to
develop and enforce rules or solve problems.

     Other participants also called for increased government
authority over aviation issues, and suggested there might be demand
for legislation that would make MTC more powerful.

     However, some officials also claimed that "politics is driven
by real estate money," distorting rational decisions about the use
of land around airports.

     "Let's be more honest about what's going on and plan around
it," another suggested.

There was general agreement that  the  updated  RAP  could  be  an 
effective  tool  for  public education and information, although one
official suggested it would be more useful if the RAP and not an
"encyclopedia."

     Officials also recommended the updated RAP anticipate likely
changes in technology.

     And they suggested that the plans forecasts and analyses take
into account important areas outside the MTC's prescribed
boundaries, including Stockton, San Joaquin Valley and the Silicon
Valley.  These areas, they said, are a vital part of the region's
aviation market and vet they are not within MTC's jurisdiction.

25


E. ENVIRONMENTAL ACTIVISTS AND AUTHORITIES (Group 6)


     Participants were recruited from a wide range of environmental
groups that are active in the region, as well as from the
environmental staffs of local government and airport authorities.

     As a result, the participants were quite knowledgeable and
recognized the complex nature of the issues to be discussed.  The
broader airport system issues provided the context for a more
detailed discussed of specific environmental and social problems,
including airport noise, safety, wetlands preservation, land use
planning, traffic congestion and economic development.

     These participants were well aware that solving one problem can
exacerbate others.  Nevertheless, they were generally unwilling to
accept or make necessary trade-offs.

     Some dismissed the common assumption that transportation demand
will grow.  Others rejected the suggestion that the airport system
must find some way of increasing its capacity to meet that demand.

     Instead, most of the participants promoted the development and
expansion of alternative modes of transportation.  Many also
advocated direct intervention with the market to slow or restrict
growth, and pursuing increased legislative and regulatory authority
to do so.

     The sharp differences in outlook between these participants and
those in the other focus group sessions points to the value of
including them early on in the planning process and developing some
means of continuing this dialogue.

Capacity and Demand

     Many participants seemed convinced that the airports currently
possess excess capacity and have no need to expand or increase
operations.  Instead, they suggested the real issue for the airport
system, is to find ways to -- as one person put it -- "Use what they
already, have more efficiently."

     This was also the only group that was unwilling to accept the
assumption that increased demand was inevitable.  Instead,
participants were much more likely to perceive the aviation market
as a "chicken or the egg" phenomenon in which increased capacity
might be more likely to stimulate and create increased demand,
rather than vice versa.

     In addition, some of the participants advocated active
intervention in the market to slow growth in the region.  By raising
rates and the cost of using airports, they hope to slow growth and
inhibit demand for air service, and thus the negative social and
environmental costs that might be associated with it.

26





The participants generally agreed that "you can't stop growth, you
can only delay it." There was a strong desire expressed to do just
that.

Transferring the Problem

     They noted that the service market extends beyond the nine-
county region and wondered why their communities might be expected
to accommodate the result of growth elsewhere.


     The real growth, they suggested, is in the Central Valley and
recommended expanding air service in Sacramento, Bakersfield and
Fresno.  They also suggested that increased demand could be
accommodated by shipping air cargo out of Stockton.

     The participants conceded that this would not solve the problem
and merely transfer it elsewhere.  Instead, the strongly preferred
to find other ways to avoid increased airport operations or
expansion.

Regulatory Authority

     Some participants were not convinced that "market forces" would
necessarily prevail in determining the future shape of the airport
system.  One person suggested that future "re-regulation" of the
airlines cannot be ruled out.  He observed that airline regulation
was cyclical, and predicted that the rapidly declining number of air
carriers would lead to increased government regulation.  This in
turn, he suggested, would provide an opportunity to seek the
additional authority that might be needed to restrict operations and
reduce negative environmental impacts.

Alternative Modes

     Many of the participants see technology as a savior.  They
expressed great enthusiasm for high-speed rail as an alternative
with a "minimal" environmental impact.  But they raised questions
about what it would cost, and recognized that it would require local
community support to obtain the necessary rights of way.  Some
expressed doubts, saving that the development of BART had been
"difficult enough" and taken a very long time to resolve and
complete.

     However, there was support for pursuing "low cost
opportunities" to improve access to area airports.

General Aviation

     Participants in this group appeared to have reservations, or at
least mixed feelings, about the role of GA airports in the system.
     On one hand, they perceive that private planes cause more of
the safety problems and noise

27





disturbances with which they are concerned.  But they also agreed
that closing GA airports would result in even greater safety
problems by mixing GA and large commercial aircraft at the larger
airports.  On balance, they seemed to favor preserving the GA and
Reliever airports.

     They also expressed a strong preference to use existing
reliever airports before resorting to Bay Fill.  Many also preferred
using these facilities instead of developing new airports.

     One participant noted, for example, that by planning to use
existing military air facilities at some later date for public
housing instead of aviation, the region would be contributing to
increased aviation demand while at the same time restricting its
ability to satisfy that demand.

     Still, there was little sympathy for the GA pilots and their
cause.  Cynical remarks were made about recent efforts to publicize
the GA airport role in emergency and disaster relief.  Some
participants clearly implied that general aviation is a "luxury" --
something unnecessary and reserved only for the benefit of the
corporate community and the wealthy.

     But others argued that GA pilots are future airline pilots and
most agreed that General Aviation provides important opportunities
for them to gain valuable experience.

Noise

     Representatives from the environmental groups seemed to agree
that reducing noise required reducing airport operations. By
restricting operations at a single airport or encouraging the
development or expansion of distant airports, they worried they
might simply be "pushing noise off on their neighbors."

     Perhaps for this reason, they placed considerable faith and
their support in promoting alternative modes of transportation.

     In the meantime, several participants suggested that the system
needs a better measurement of single event noise to accurately
reflect the disturbance of nearby households.

Improving the RAP

     The participants strongly suggested that planning activities
occur in a longer-term context.  They recommended the next RAP look
beyond the next 10 years because it takes so long for changes to be
put in place.

     They also expressed a desire to convert military spending to
address these environmental issues while also assisting with the
economic development of the state.



28

F. PILOTS (Group 5)


     Participants in this session were pilots who use airports in
the nine-county Bay Area region, including commercial passenger and
cargo, military, non-commercial general aviation and corporate jet
pilots.  Although each of these constituencies was represented in
the session, the discussion was dominated by the GA pilots who
turned out in larger numbers.

     This session was by far the most heated and passionate.  If
nothing else, it demonstrated most clearly the importance and value
of meeting with individual constituency groups -- not only
soliciting their input, but also involving them directly in the
actual planning process through the use of in-depth focus group
discussions.

     It was clear from the start that the GA pilots feel
disenfranchised politically from the airport system and the planning
process.  Considerable time was spent venting frustration and anger,
and debating whether their input would have any real impact.

     Nevertheless, the pilots were eventually guided to a more
constructive and in-depth discussion.  The pilots strongly support
the development of GA and reliever airports and believe they play a
crucial role in the airport system.  They perceive the very
existence of these facilities, however, is now threatened by
unilateral political action from local communities.

     Their discussion focused primarily on the relative merits of
various methods available for preserving GA and Reliever airports in
the system.

The Role of GA and Reliever Airports

     Aviation is "here to stay" and, according to these pilots, it
represents much more than just the "Big three" air carrier airports
in the region.  The smaller GA and Reliever airports play a vital,
but under-recognized role in the region's aviation system.

     These pilots strongly favor the development of existing GA and
Reliever airports to help meet future increases in system-wide
demand.

     In their view, finding adequate locations elsewhere would be
most difficult.  Starting from Scratch would require significantly
more time and money.  They also suspected that constructing airports
on new sites would result in even greater negative impacts on the
environment.

     In contrast, they suggested that Hamilton Field -- an existing
facility -- would be  "ideal"  for development and minimize the
negative impact.  In their words, Hamilton is a "true reliever


29

airport" that could provide much-needed commuter service.  The
pilots said they are convinced that businesses would re-locate and
use the airport if it were developed.

     They also advocated the conversion of Moffett Field for either
General Aviation purposes or air freight.  Other airports in the
system were also mentioned as possible candidates.

     These airport sites exist in their current locations, one pilot
exclaimed, because they serve the demographics of the area.  These
locations are convenient, he argued, and it makes little sense to
move airport activity out to Salinas or Modesto.

Preservation as a Goal

     But for these pilots, the most pressing issue is not the
enhancement or expansion of GA and Reliever airports.  Instead, they
are convinced the mere existence of these airports is being
threatened by local communities.

     The pilots said these assets are virtually "irreplaceable," for
the reasons noted above.  And without these facilities, they said
the region will not be able to meet increased demand for air service
or respond adequately to calls for emergency and disaster relief.

     Nevertheless, the pilots perceive they are losing a fight for
their lives, that they command little of the support they deserve,
and that the problem is largely political.

     Politicians in the region have been "irresponsible," catering
to "real estate money" and the needs of developers, they said. 
These politicians have staunchly opposed to airport growth and now
threaten to close them down.

     One pilot lamented that a "747 with 450 passengers has more
rights than one GA pilot," expressing a sentiment that permeated the
morning's discussion.  The pilots agreed there is little
appreciation or recognition of the vital role that reliever airports
play in the commercial aviation system.

     They also believe that the major commercial airports should
include them in their planning, to preserve needed capacity for the
future.

Possible Strategies and Approaches

     The pilots discussed a wide range of possible strategies for
preserving the GA and Reliever air-ports, focusing on the relative
effectiveness and likely success of each approach.

Regional Planning

     These pilots strongly support regional planning and desire more
input into the planning process.  They observed that planning
activities are fragmented, instead of integrated.  As

30

a result, one pilot concluded, "the reliever airports get lost in
the process."  In the absence of strong regional planning, the GA
pilots are caught in the middle and get "squeezed the most" when the
larger commercial airports compete or have differences among
themselves, they explained.

     The pilots believe that a regional planning authority could be
more "objective" in settling differences or disputes.  In their
view, this offers a greater chance for preserving the GA and
Reliever airports because there would be a greater emphasis on long-
term benefits and the needs of the entire region.

     However, the pilots also perceive that none of the numerous
regional planning authorities, including MTC and ABAG, have enough
power or "teeth" to defend larger regional needs against local
politics.  For that reason, they said they would support efforts to
grant MTC greater authority to encourage compliance with regional
policies and enforce regulations.

Public Relations and Education

     Others suggested a wide range of public education activities,
including teaching pilots how to minimize noise impacts more
effectively.  Some pilots suggested a more aggressive public
relations campaign, publicizing the key role that GA airports play
in emergency and disaster relief, for example.  Some recommended
town meetings to educate the public and provide a forum for
addressing their concerns.

     One pilot suggested they improve communication with political
decision-makers, and take them on flights around the Bay Area to
increase their appreciation of general aviation. its special needs
and its current and potential contributions to the region.

Independent Research

     Another said more analysis is needed, perhaps from MTC, to
evaluate the economic impact of the reliever airport system.  The
results of this study could later be publicized.

     The pilots also suggested that MTC conduct an independent
research study to determine which GA and reliever airports could be
developed most effectively and identify the ones where improvements
are politically most feasible.

Land Use Zoning

     The pilots also said that MTC should do more to get airport
owners to comply with state laws on land use, and that local
community officials needed to be better informed about what federal
grants require in this area.  They agreed that Solano County has a
good land use board, and praised the city of Tucson for its land use
law.


31

Financing

     The pilots argued that new incentives need to be developed to
encourage cities to support the GA and Reliever airports.  These
airports, they explained, are not profit centers themselves and are
unlikely to receive significant assistance from the major commercial
airports.

     Many of the pilots agreed that federal grant money should be
tied to appropriate improvements to reliever airports.  They support
efforts to gain greater support from the major commercial airports,
and would favor a regional airport plan that would include
provisions for integrated system-wide financing.

     The pilots were also very concerned that cities and counties in
the Bay Area might be turning down federal money that could be used
to develop GA airports.

Legal Action

     One participant was most adamant in his claims that litigation
is the best and probably only chance for preserving the GA and
reliever airports.  The other participants seemed resigned to the
possibility that, having tried other approaches, it might be time to
resort to legal action.

Noise and Safety

     The pilots agreed that noise complaints could be alleviated
significantly through more effective education of pilots.  They also
placed much of the blame on poor land use planning and zoning around
airports, again citing a lack of responsible political leadership.

     Some participants suggested that noise complaints from
overflights actually reflect underlying concerns about safety.  The
pilots expressed confidence and pride in their safety record, but
complained that the public has much higher standards for air travel. 
These expectations are both unrealistic and unfair, they said.

     "You have to recognize we're going to have some accidents," one
pilot explained.  All transportation systems will have accidents,
and a single plane crash should not suggest that air-planes are
unsafe.  But they noted with some frustration that such a crash
anywhere in the country can erase months of hard work in trying to
build good will locally.

Other Issues

     The pilots also noted that the system should consider the role
that helicopters might play in relieving congestion, and especially
in emergency preparedness, disaster relief and medical emergencies. 
They noted that San Francisco is one of the few cities to have
banned helicopter traffic and that few helipads are available or
operational in the Bay Area.

32

G. BAY AREA FREQUENT FLYERS (Group 3)

     Participants for this focus group represent a cross section of
about a dozen Bay Area frequent flyers who use the regional airport
system, including travel for business and other reasons.  Most of
these frequent flyers live or work near San Francisco and use SFO. 
However, they also reported using other airports in the system,
including OAK.  To qualify as a frequent flyer, participants had to
have flown six or more times in the past 12 months.

     From this discussion, it was clear that problems with
congestion, ground transportation and airport access have begun to
take their toll on these travelers, especially at SFO.  They say
they actually prefer OAK because it is smaller and friendlier, but
use SFO more often because it offers more flights, more choices and
lower fares. This poses a dilemma for airport managers and regional
planners alike.

Quality of Air Service

     Frequent fliers from San Francisco said they would like to fly
more frequently from Oakland but are unable to do so because most
direct flights are from San Francisco.

     They described their experiences at SFO in largely negative
terms, complaining that the roadways are congested, parking is
expensive, and customer service is poor.  They said the airport is
large and impersonal and the employees are rude.  One participant
summed up by calling SFO "insular and insensitive to the customer."

     Despite these complaints, they continue to use SFO and desire
even more frequent flights.  They perceive that Los Angeles has more
international service then SFO, and did not think it unreasonable to
expect "at least one direct flight each day to anywhere."

     Ironically, these same frequent flyers say they greatly prefer
OAK because it is a much friendlier, compact airport with short
walks and pleasant staff.

     Nevertheless, they end up using SFO because it has more direct
flights, more destinations and choices, and the lower fares that
come with high volume.  These positive factors apparently outweigh
the negatives responsible for their obvious dissatisfaction.

     The participants said they hoped the market could be divided up
more evenly so that Oakland could gain more flights.

     But ground transportation and access are clearly important
factors in their decisions.  The group. wished for flights scheduled
away from peak commute times so they could avoid traffic congestion. 
And they were more interested in getting easier access to Oakland
than in greatly expanding the airport or the number of flights.

33


     They said they would be more likely to use OAK if it were more
convenient, and that heavy discounts would be necessary before they
would switch airports on price alone.

     At least one participant said they would like to see the number
of flights in and out of Concord increased because that airport was
even more convenient to their home.

Ground Transportation and Access

     Although ground access is a critical factor in their choice of
airports, it is not the mere distance that matters.  Instead, these
frequent flyers consider the time it takes to travel "door to door,"
including the time spent on the highway, in the parking lot, and
walking through the airport.

     They have also adopted a wide range of "guerilla" tactics to
cope with traffic congestion and other access problems at SFO,
including listening to the radio for traffic reports and changing
their routes or flight times at the last minute.

     For example, several reported that to avoid the high cost,
uncertainty and hassle of airport parking, they leave their vehicles
at nearby hotels and receive a shuttle ride directive to their
terminals.  Others said they always have someone drive them or drop
them off at the airport.

     These measures are not necessary at OAK they explained, because
you can park directive across from the airport and get to your gate
quickly and easily.  However, they said getting to Oakland itself
was a problem.

     About half of the participants said they would use a ferry
across the Bay if it was "reliable." Some saw this as one way to
avoid bridge traffic and make Oakland airport more accessible and
convenient.  Helicopters were also mentioned as an option.

BART

     The participants favored the extension of BART into San
Francisco International Airport, believing this would make it more
convenient for others and reduce congestion and parking problems. 
But they said they personally were not likely to use it, citing a
wide range of obstacles.

     These people said it was difficult to get around BART with
luggage, and that most of the stations had long staircases.  They
also cited concerns about safety, especially for women travelling at
night or business travelers with valuables.

     They Added that using public transit  required  too  many 
changes,  and  that  it  didn't  allow them to "cut it close." Some
explained they often dashed  to  the  airport  at  the  last  minute
and needed the flexibility of an automobile.

34





Intermodal Connections

     The participants agreed that the congestion problem at SFO is
partly due to the lack of alternatives -- many people drive simply
because the different transit systems in the Bay Area do not link to
one another.  There was strong support for developing better
intermodal connections in the region's transportation system.

Remote Terminals

     The participants thought that remote terminals might be a good
idea if they saved time, but they said they disliked shuttle buses
because of limited space and uncertainty about when they would
arrive.  Dedicated indoor shuttles, however, earned their praises.
     Again, these frequent flyers put a high premium on convenience
and flexibility -- getting to their flights quickly and with as
little effort and frustration as possible.

Alternative Modes

     Many participants leave a da early on business trips for fear
of being delayed and missing important meetings.  Others reported
that delays on the ground and in the air have forced them to choose
alternative modes of transportation, saying they no longer fly to
locations such as Lake Tahoe and Monterey because it has become
faster to drive.

     There was also interest in the concept of high-speed rail
service to Los Angeles, but many were not sure that it would be
feasible or viable.

35

H. RESIDENTS NEAR AIRPORTS (Group 4)


     Participants in this focus group represent a cross-section of
Bay Area residents who live near a major commercial airport, in this
case San Francisco International Airport.  Residents were selected
from communities adjacent to SFO, including San Bruno, Burlingame
and Millbrae.  The group included both frequent flyers, occasional
flyers and non-flyers and people who use SFO as well as other
airports in the system.

Quality of Life

     These participants are highly satisfied with the quality of
life in the Bay Area, with many saying they specifically moved to
their present communities with these benefits in mind.

     Among the most frequently cited benefits or positive attributes
were cultural and recreational opportunities, and good public
services including education and transportation.

     The residents living in areas near San Francisco International
Airport agreed that, on balance, the airport contributed to the
overall quality of life.  Most of them reported using SFO.  And
though the residents said there were some negative aspects of living
near an airport, they were outweighed by the benefits.

Convenient Airport Access

     Most important was the easy access to the airport even during
peak periods.  Even if they were not frequent flyers, most said they
used the airport to drop off and pick up friends and family members. 
Even with congestion, their estimated travel times did not exceed 20
or 30 minutes.

Economic and Cultural Benefits

     There was also widespread recognition of the economic benefits
generated by the airport, especially in providing jobs for people
throughout the region.  Some suggested the benefit was especially
important to workers in the service sector.  Participants also
believe these cash flows are vital to the region and responsible for
much of its development.

     In addition, they said the airport has helped make San
Francisco an international gateway, making the area more accessible
to travellers.  This benefits the entire community, they said.

     They also see the airport as playing a key role in promoting
the "cosmopolitan" nature of the area, offering increased
opportunities for culture, merchandise and recreation.



36





Participants generally agreed that strong regional planning was
necessary to ensure that they continued to enjoy a high quality of
life in the region.

Negative Airport Impacts

     These residents also discussed their concerns about the
negative effects of the airport, including noise, air pollution, and
safety.  Although they said traffic congestion was also a problem,
they perceived the airport is not a key contributor.

Pollution

     Pollution was a major concern for many of these residents. 
They complained of unpleasant odors caused by jet fumes on calm
days.  Participants also discussed other environmental concerns,
such as hazardous waste and water pollution that might be caused by
aviation or the airport.

Noise

     Residents said that noise is rarely a major problem for them
personally, becoming a nuisance only on overcast windy days.  This
might suggest the problem arises during crosswind runway use.  They
were most annoyed by aircraft noise at night, and seemed more
concerned about  possible  damage  from  aircraft  vibration, 
window  rattling  and  air  crashes.

     This is not to say the noise problem is not more severe for
other residents of the Bay Area who may not have been represented in
this particular group.

     These participants, however, said they had grown accustomed to
the noise and seemed to accept it as an inevitable part of living in
a metropolitan area.

Safety

     The residents said they were concerned about safety, but did
not worry about it on a daily, basis.  In fact, they marvelled at
the lack of accidents given the amount of traffic, specifically,
citing the ability of planes to line up "six deep" without
colliding.

     And while they perceived the likelihood of a major crash Was
remote, they recognized the consequences could be devastating to
their communities.  Like the potential hazard of earthquakes, this
is a risk they said they are willing to accept.

Ground Transportation and Access

     While.many of the residents felt that access had improved with
a route paralleling Highway 101, they also suggested that ground
transportation at the airport could be made much more efficient.

37





     Specific suggestions included better signage, improved traffic
flow and increasing the number of handicapped parking spots.  They
suggested that more be done to eliminate double parking and remove
other obstacles to smooth traffic flow.

     The participants expressed concerns about the safety of using
long-term parking and riding shuttles to and from the terminals.

     Residents said they are not currently served by public transit
and desire better access to BART.

Accommodating Increased Demand

     The residents seemed to recognize that the airways are growing
more congested, and discussed ways the regional airport system might
accommodate future increases in demand.

     Some participants agreed that a smaller airport should be
developed for smaller aircraft and that more cargo or passengers be
moved from SFO to Oakland to alleviate congestion.

     Others expressed confidence that the problem was manageable
without major changes to the system, and were generally opposed to
suggestions that airport operations be more decentralized.

     Residents were divided on the merits of increasing system
capacity through the use of Bayfill.  But they said they were more
concerned that the Bay might be filled for condos or housing
development, and would be less likely to object if use were
restricted for runways only.

I. SOUTH BAY FREQUENT FLYERS AND RESIDENTS (Group 7)


Participants in this focus group included both frequent flyers and
residents of San Jose and the South Bay area.  Some were selected to
represent a cross section of people who live near one of the
commercial or General Aviation airports in the San Jose area. 
Others were selected because they were frequent flyers who use the
San Jose airport.  There was some overlap between the two groups,
and many reported they had used other commercial airports in the Bay
Area region, including OAK and SFO.

Airport Development and Local Impacts

These South Bay residents agreed that the San Jose airport is vital
to local business and industry, particularly area hotels and
restaurants.  Long-distance business travelers now stay in San Jose,
they observed, instead of commuting back and forth from San
Francisco.

American Airlines' decision last year to make San Jose a hub has
"transformed" the airport they said, resulting in many major
improvements.  The airport is now more "modern" and impressive" in
appearance, according to one resident.  Some said they were
"embarrassed" in the past when visitors were forced to board and de-
plane outdoors.

These changes, however, have also generated "mixed feelings" among
these residents and frequent flyers.  The San Jose air-port is no
longer the small "cozy" facility it once was, and many of the
participants strongly fear that without carefully-planned growth it
will turn into "another San Francisco."

But there was general consensus that current airport development was
catching up to population growth from the 1980s, rather than
stimulating unwanted growth.  Participants said there were traffic
problems and a population boom before the airport expanded, so they
do not blame the airport for related problems.

Airport Use and Preferences

Despite their mixed feelings about airport expansion, the vast
majority said they would still much rather use SJC than fly from San
Francisco International Airport.

Airport users expressed great dissatisfaction with SFO, citing long
traffic delays, inadequate signage, expensive parking, poor parking
facilities, and poor customer service.  One participant said it
takes 45 minutes to return to the airport from long-term parking. 
Another complained about the "surliness" of the staff at SFO.

     In contrast, they said that despite recent expansion, San Jose
remained a "user-friendly" airport with a pleasant staff and
convenient short-term parking right across from the baggage

39




claim area.  They also noted the airport has less traffic and
congestion.
     But although most of their desired destinations can be reached
from SJC, the participants said flight times are quite limited and
few direct flights are available.

     As a result, they say they continue to use the San Francisco
airport because it has more frequent flights, more direct flights
and the lower fares that come with high volume.

     Lower fares and better flights would be necessary for these
people to use their preferred airport more often.  In fact, given a
choice between the two, many flyers said cost was the primary
determinant and they would be willing to adjust their schedules.

     Participants said they recognized the trade-off between keeping
San Jose a small friendly airport and gaining the additional flights
(and lower fares) they desire.  They hoped nonetheless that
congestion and other problems experienced at SFO could be controlled
through more effective planning at San Jose.

     They also noted that while Oakland was no further away than
SFO, the flights and prices were usually no better than those
available from San Jose and certainly not SFO.

Ground Transportation and Access

     Ground access to the airports remains a serious problem for
these participants.  They also expect that parking, access and
congestion will worsen significantly as San Jose airport grows.

     They noted that access at SJC is limited to only a few exits, a
major drawback they perceive that causes delays.  Some participants
also objected to the "incremental" construction of the San Jose
airport because it requires people to physically leave the building
in order to change terminals.

     Some suggested a feeder from Caltrans to the airport would be
useful, and might alleviate future traffic congestion and parking
problems.

     They observed that the existing transit systems are only as
good as their weakest link -- the inability to connect to other
transit systems.  There was strong emphasis on the need for better
intermodal connections and interest in a system that linked all
three airports.

     As they began discussing ground transportation, there appeared
to be considerable interest in extending BART to San Jose.  But
later support faded when people concluded that BART service would be
no better than the Caltrans trains and would not be widely used.


40





Noise and Other Problems

     As in similar groups, these residents did not complain
strenuously about airport noise problems.  Again, this is not to say
that other residents may not be bothered by noise in the South Bay
area.

     The participants agreed that the noise problem is worse at
Moffett Field.  Others noted that business development has occurred
right along airport flight paths, so that flights can be heard and
often seen outside the windows of local office buildings.

     Some participants said they were frightened by overflights, and
that there concern was more related to safety.  Noisy aircraft
apparently remind people of the possible safety threat.

General Aviation

     Opinions were more mixed and divided when it came to General
Aviation, and Reid-Hillview in particular.

     There was a strong consensus that smaller airports like Reid-
Hillview are unsafe and that activities and operations should be
restricted.  Some residents argued strongly that Reid-Hillview
should be shut down entirely.

     One the other hand, some observed that the airport existed long
before most of the housing, surrounding Reid-Hillview.  And they
suggested that people who live near the airport made a conscious
choice to live with that risk.

     Others responded that lower income households often have less
choice in where they live or what they can afford, and that the
number of flights can greatly increase after one has purchased a
home.

     Participants agreed, however, that the problem can be traced to
poor planning and the failure of the local community to develop
adequate zoning.

Accommodating Future Demand

     Nevertheless, participants were quite enthusiastic about the
possibility of converting Moffett Field into a reliever airport. 
They seemed to support the reliever airport concept as a means for
adding system capacity and meeting increased demand.

41




     The participants agreed that demand will continue to grow, and
recognized limits on the ability of SJC to expand indefinitely.  And
they recommended a strategy in which:

   (1)  Activity or operations are not increased at "populated"
        airports,

   (2)  Less populated airports are expanded or new airports are 
        built  in  unpopulated areas, and

   (3)  Strict zoning is established and enforced to  prevent 
        residential  development.


     Participants described Moffett Field as convenient, large and
mostly non-residential.  There were suggestions this facility might
provide an escape to the contradictions inherent in their desire for
more choices and opposition to airport operations in their own "back
yard."

     They also expressed concern about the effectiveness of planning
efforts.  In the past, they said, there has been little local
planning and no regional planning in the area.  Most of the regional
authorities, they suggested, focus on San Francisco and Oakland and
overlook or neglect the South Bay.


42




III.   SUMMARY OF KEY FOCUS GROUP FINDINGS


     Focus groups with a wide range of Bay Area constituencies with
an interest in the Regional Airport System revealed the following
findings:

   -    There is widespread demand for information and strong action
        -- and little awareness of the 1980 Regional Airport Plan
        (RAP).

   -    MTC and the RAP Update should anticipate increases in
        demand, and decide whether or not to facilitate re-
        distribution or re-allocation of demand.  Consumers say they
        would make greater use of OAK and SJC if it were more
        convenient and affordable.

   -    Ground access is perceived to be the most critical issue
        facing the system in the near term.  Specifically, this
        includes improved access to airports and improved intermodal
        connections.

   -    There is widespread recognition of the need and desirability
        of minimizing environmental impacts, also acceptance that
        this will constrain growth.  But no clear priorities or
        consensus on trade-offs is apparent.

   -    There is broad agreement on the "vital role" of GA and
        Reliever Airports, but little positive action is expected:

        -- Preservation is the real issue (not facility
        enhancement).  The importance of preserving facilities will
        be even greater in the future, as system capacity, falls
        behind growing demand.

        -- Most agree that use and development of existing airport
        facilities  makes  sense,  and that development is also in
        the interest of the major airports.  Yet there  is  strong
        political opposition locally and little expectation for
        positive action.

        -- Key opportunities include Hamilton Air Base, Reid-
        Hillview and Moffett Field.


   -    People generally perceive the airports to be a key asset to 
        the region, contributing to both the economy and the overall
        quality of life.  And they want action to preserve these
        benefits.

Executive Summary




     This report describes ACCESS, a software package for analyzing
airport access and airport competition in a multiple airport region. 
ACCESS is a tool for studying policies and trends that influence: 1)
the distribution of air travelers among airports; and 2) the
patterns of use for airport access modes.  It permits the user to
quickly and easily analyze current patterns of airport choice and
access mode use, and to test the effects of alternative traveller
and service attributes.  It is suitable for airport-by-airport
studies of ground access as well as for regional airport system
planning.  As local governments work to manage their airport
resources more efficiently, it is hoped that the ability to
anticipate market responses which ACCESS provides will aid in sound
decision-making,

     ACCESS incorporates a set of models of airport choice and
access mode choice developed for the San Francisco Bay Region, using
data from a survey of air travellers as well as a detailed
representation of ground access and airline service at each airport. 
In forecasting, the models are used with a database that is
organized around an actual sample of air travelers, derived from the
most recent MTC Air Passenger Survey.  The models and passenger
sample are used with a database of access and airline service
characteristics to obtain mode and airport choice probabilities for
each traveling party.  ACCESS then sums up these probabilities and
produces estimates of regional and sub-regional passenger volumes
and related outputs.  By modifying the database, the user can assess
the effects of a variety of scenarios involving different traveller
characteristics, airport access services, airline services, and even
airport locations. ACCESS is designed to permit such scenarios to be
tested quickly and easily.

     The report demonstrates the use of the software through three
examples, including one that focuses on the effects of a BART
extension to the San Francisco International Airport.  A concluding
section outlines a set of enhancements that would further exploit
the potential of the modeling approach.  In an extensive set of
appendices, the report describes the database and presents a user's
manual on the basics of program operation.





I.1     Introduction

     The  report  describes  'ACCESS',  a  software  package  for 
analyzing  airport   access   and     airport competition in a
multiple airport region.  ACCESS simulates air travel patterns in
the region by representing the effects of price and level of service
on the behavior of a sample of air travelers.  For a specified set
of service attributes and traveller characteristics and a regional
air travel demand total, ACCESS will estimate airport choice and
access mode use in the region.  Either actual data sources or user-
created scenarios can be readily used with ACCESS.
     ACCESS is designed for studying policies or trends that
influence the distribution of air travelers among airports and
access services.  It permits the user to quickly and easily analyze
current patterns of airport choice and access mode use, and to test
the effects of alternative traveler and service attributes.  It is
suitable for airport-specific studies of ground access as well as
for regional airport system planning.  Because it deals with the
market effects of significant changes in travel time and travel
cost, it complements rather than substitutes for existing landslide
analysis tools, which most often address fine-grained operational
issues.  As airports work to manage their landslide resources more
efficiently, the ability to anticipate market responses which ACCESS
provides can be expected to aid in sound decision-making.
     The models of airport choice and access mode choice contained
in ACCESS were developed for the San Francisco Bay Region using data
from a survey of air travelers as well as a detailed representation
of the ground access and airline services at each airport.  The
models operate with a database of air traveler characteristics and
access and airline service characteristics to obtain mode and
airport choice probabilities for each traveling party.  ACCESS then
aggregates these probabilities into regional and sub-regional
passenger volumes and related outputs.
     The prototype for ACCESS (Version 1.0) was developed by the
author in 1986 [Harvey: 1986, 1987a, 1987b].  This earlier effort
sought to demonstrate that software based on discrete choice models
and designed to simulate the behavior of a sample of air travelers
could serve as a practical source of information for airport
planners and decision-makers.  Models in the original program were
based on 1980 survey data for resident air passengers from the San
Francisco Bay Area [MTC, 1981].  In 1987, the Metropolitan
Transportation Commission (MTC) funded the current project to update
the program and extend it to non-resident passengers as well, using
1985 Bay area survey data [MTC, 1986].  This report documents the
result of that effort.
     In the remainder of Part I of the report, a brief overview of
ACCESS is provided.  Part II of the report then presents the ACCESS
models, and Part III describes the software.  Part IV demonstrates
the use of the software through three examples, including one that
focuses on the effects of a BART extension to the San Francisco
International Airport.  Part V then assesses the software's current
capabilities and outlines a set of enhancements that would more
fully exploit the potential of the modeling approach.  In an
extensive set of appendices, the report describes the database and
presents a user manual on the basics of program operation.


1.2 Overview of ACCESS

     At the core of ACCESS are models that depict the airport choice
and access mode choice behavior of the air traveler.  They employ a
multinomial logit form [see, e.g., Ben-Aldva and Lerman, 1985] and
rely on variables such as access time, access cost, household
income, party size, and frequency of airline service to explain
variations in behavior.





     The models in ACCESS operate on a database which includes, for
each air travel party, detailed information on the air trip(s) being
made and each air traveler's socioeconomic characteristics, as well
as the travel conditions to each airport by each mode of ground
transport and the airline service characteristics to each air
traveler's destination.  The data may be taken from traveller
surveys and records of actual transportation service
characteristics, or may represent a scenario created by the user. 
ACCESS then functions essentially as a device for tabulating the
database.  It uses the models to calculate mode choice and airport
choice probabilities for each traveling party, as well as passenger
or vehicle flows by mode to each airport and a host of impact
measures such as revenues, vehicle miles traveled, and user
benefits.  These items become a temporary part of the record for the
party, and the program aggregates them to produce results on a
regional and/or sub-regional basis.
     ACCESS allows certain policies or scenarios to be tested
through an interactive procedure.  The user can define broad changes
to the database for the program to apply as it processes each
observation.  For example, all transit travel times in a given
corridor can be reduced by ten percent (to reflect improved transit
service).  The user simply enters the changes he or she wishes to
explore, and the program automatically transforms the data and runs. 
The results can be compared with outputs of other runs (such as a
"base case") to assess the effects of proposed policies.  No
permanent changes to the database result from this procedure.
     More specific and detailed policies or scenarios can be tested
by creating a new database and then running the program.  For
example, new level of service data reflecting the addition of a new
transit station can be defined; or a detailed new airport parking
price structure can be specified.  The new database then can be used
with the program, and the results compared to those from the
unmodified database.
     An extensive set of spreadsheets is provided to assist the user
in the preparation of new databases.  Thus, with the possible
exception of cases in which a new network ordinarily would be coded,
the user should not have to interact extensively with data
processing staff or with other computer specialist in order to
operate ACCESS.1
     ACCESS runs on a microcomputer with 640K of system memory,
using the MS-DOS operating system (Version 2 or higher).  A math co-
processor is required.  Computation time for a typical scenario
depends on the complexity of the regional airport system, on the
desired level of aggregation in the outputs, and on requirements for
accuracy (i.e., on the number of observations in the sample).  On an
80386-based PC-compatible computer, using Bay Area data and a sample
of 8,000 air parties, execution time for the basic ACCESS module is
about three minutes.2
