Tri-Valley Action Plan Proposal for Adoption
MARCH 6, 1995
BACKGROUND/REASONS FOR RECOMMENDATIONS
The Transportation Committee, February 6, 1995, initially reviewed the Tri-
Valley Action Plan Proposal for Adoption. Based on its review and public
responses, the Committee requested that staff organize a Transportation
Committee Workshop, February 13, 1995, to discuss the Action Plan as it relates
to the County's land use decision-making authority.
At the March 6, 1995 Committee meeting, staff underscored for the Committee the
conflicting Town of Danville and County versions of Action Plans for Sycamore
Valley Road, Crow Canyon Road, and Camino Tassajara Road. The Contra Costa
County Transportation Authority staff (CCTA) also indicated that these
conflicting versions of Action Plan policies will cancel each other and not be
the basis for denial of Measure - C " return of source funds. "
County Counsel staff, March 6, 1994, gave his opinion that the Action Plan
contains certain unclear or conflicting language that appears to obligate the
County to go beyond the minimum requirements of Measure - C (1988) for return-
of-source .funds. Jurisdictional violation of TSO's would be the basis of denial,
such as the County approving a General Plan Amendment in the Tassajara Valley
that would exceed TSO' s for various road facilities in the Town of Danville.
The County in this situation would have the recourse to' request that the Tri-
Valley Transportation Council (TVTC) amend the Action Plan, requiring a
unanimous agreement, to alter Action Plan policies to accommodate the County's
General Plan Amendment. This Action Plan amendment requirement would, therefore,
dilute the Board of Supervisors land use discretionary authority and delegate
it to the TVTC. Approving the General Plan Amendment in this situation without
amending the Action Plan would be the basis for denial of Measure - C return of
source funds
County Counsel advises that to retain maximum discretion in land use planning
decisions the County should clarify the Action Plan language to match Measure
C's requirements. The Transportation Committee, in consideration of County
Counsel 's opinion, recommended that the Director of Community Development, with
assistance from County Counsel, delete language from the Action Plan that
negates and limits the Board of Supervisors discretion in land use planning
decisions.

Executive Summary
The purpose of the Tri-Valley Transportation Plan is to address transportation issues
through the year 2010 within the Tri-Valley area including Danville, San Ramon, Dublin,
Pleasanton, Livermore, and unincorporated areas of Contra Costa and Alameda County.
This document is in addition to existing policies, agreements, and regulations that.exist in
each jurisdiction or between jurisdictions. The study area and the primary roads are
shown in Figure, E-1. In addition to serving as a guide for transportation planning
through 2010, this document represents the Action Plan for Routes of Regional Signifi-
cance for Contra Costa County jurisdictions, as mandated by Measure C. This document
also provides information that can be incorporated into the Congestion Management
Programs for Contra Costa and Alameda Counties. The Tri-Valley Transportation Plan is
the culmination of a four-year work effort to identify existing and future transportation
deficiencies and identify a financially feasible transportation plan that addresses the
deficiencies.
The Tri-Valley work was overseen by the Tri-Valley Transportation Council (TVTC), an
advisory board of representatives from each of the seven Tri-Valley jurisdictions. Funding
for this effort was shared equally by the Contra Costa Transportation Authority and the
Alameda County jurisdictions. The consulting firm of Barton-Aschman Associates, Inc.,
through a series of meetings with the TVTC, prepared the study.
Existing Transportation Issue's
The study was initiated in 1991 with parallel efforts to develop the Tri-Valley Travel
Forecasting Demand Model and assess study issues and existing conditions. Discussions
with representatives from each community and preliminary technical analysis culminated
with the following findings:

Executive Summary
1. Tri-Valley is relatively free of congestion.
2. Transit use is relatively low—four percent of total trips.
3. Existing average vehicle occupancy is about 1.1 for commute trips.
4. There are 14,000 more employed residents than jobs, so there is net out-commuting.
5. I-680 and I-580 are major regional highways. Each has 15 to 20 percent through
traffic.
2010 Traffic Conditions
Once the study issues and existing transportation system characteristics were identified,
staff used the Tri-Valley Transportation Model to evaluate land use forecasts and
alternative transportation systems. The land use forecasts were first developed in
consultation with the Association of Bay Area Governments (ABAG) and MTC. When the
plan was started, ABAG's Projections '90 were the most current forecasts available.
Projections '90 did not include forecasts for the year 2010. These forecasts were extrapo-
lated from Projections '90 year 2005 forecasts in consultation with ABAG. Once developed,
the TVTC determined that the forecasts did not reflect current land use or network
planning.
The TVTC refined the land use forecasts.and transportatio4 networks to reflect current
general plans and Projections '92, which had significantly increased employment projec-
tions for some Alameda County jurisdictions. The "expected" land use forecasts were
evaluated along with an "expected" transportation system. The results of this evaluation
were as follows:
• Highway gateways to the area (I-680 north of Alamo and south of Route 84, I-580
over Dublin Grade and Altamont Pass, Crow Canyon Road at the county line, and
Vasco Road) will have more demand than capacity. This would occur even without
growth in the Tri-Valley due to regional traffic demands.
• With some locally funded modifications, the majority of the arterial system within the
Tri-Valley will operate at LOS D or better.
• I-680 and I-580 within the Tri-Valley will operate at LOS E or better, provided ramp
metering and HOV lanes are installed.
• Jobs and housing growth for year 2010 is projected to be 99 percent and 84 percent,
respectively. Jobs and housing would be in balance, that is, one job would exist for
every employed resident. Provided there is a match between housing prices and
salaries, this minimizes but does not eliminate in-commuting and out-commuting. The
1990 ratio of jobs to employed residents was 0.91. In 2010 the ratio is expected to
increase to 0.99.
Barton-Aschman Associates, Inc. ix
Executive Summary
• The transit mode share will increase slightly from existing conditions.
• Average vehicle occupancy will not change appreciably from existing conditions.
The Tri-Valley Transportation Plan
The model results of the "expected" land use and "expected" transportation system were
the basis for the Tri-Valley Transportation Plan. The Plan is not projected to relieve all
traffic congestion in Tri-Valley. Levels of service on some arterial segments and on -
freeway segments at the gateways will remain below E.
Based on the results of the alternatives testing, the TAC and the TVTC decided to focus
the ultimate improvement plan on the arterial corridors within Tri-Valley rather than the
Tri-Valley gateways. The plan must address the primary question: What can we do to
achieve the best level of service within the Tri-Valley?
Three contributing factors influence the ability to respond to this question.
• Financial constraints.
• Physical limitations within corridors.
• Development pattern.
Financial resources for all projects are limited. The Measure C and Measure B.sales tax
programs provide substantial funding for specific projects in Tri-Valley. Other projects
must compete for the relatively small pot of public funds. Developer fees, which have an
upper limit, could help supplement public funds. Future sales tax or gasoline tax initia-
tives may or may not be successful.
Expansion of major corridors within Tri-Valley is limited due to existing development and
terrain. These limitations hinder the development of transportation corridors other than
the existing I-680 and I-580 corridors.
Development patterns within Tri-Valley have been geared toward relatively low housing
and commercial densities. These patterns are expected to continue in the future. This
development pattern is impossible to serve thoroughly with transit, given realistic funding
expectations.
The plan proposes no increases in gateway capacity for single-occupant vehicles. "Gate-
ways" are the regional roads that connect the Tri-Valley to adjoining areas. This will help
to meter traffic in and out of the area. The plan balances the internal transportation
network with planned growth through the provision of several roadway and transit
improvements. Figure E-2 shows the transportation plan network.

Executive Summary
Transportation Service Objectives
A key element of the plan is the list of Transportation Service Objectives. These are
objectives that the Tri-Valley cities and counties should use as a guide to making
transportation and land use decisions. In Contra Costa County under Measure C, the
jurisdictions are required to make a good-faith effort to comply with the transportation
service objectives on routes of regional significance or risk the loss of return-to-source
funds. In Alameda County once the plan is adopted, individual jurisdictions are responsi-
ble for maintaining Transportation Service Objectives through their general plans. The
transportation service objectives adopted by the TVTC are as follows: -
• Maintain Level of Service D (V/C < 0.90) on arterials, and measured at intersections.
• Maintain level of Service E (V/C < 0.99) on freeways.
• Maintain Level of Service E conditions on I-580 for no more than four hours per day
(except on Altamont Pass) and on I-680 for no more than eight hours per day.
• Do not increase capacity for single-occupant vehicles at gateways.
• Increase average vehicle ridership for commute trips by 10 percent.
• Increase the transit mode share through providing express transit travel times that
are competitive with autos.
The TVTP is not intended to be a land use control document, such as a General Plan.
While the plan is based on a set of growth assumptions, the plan should not be interpret-
ed as limiting growth to the assumed levels. Nevertheless, the plan does establish
Transportation Service Objectives, which may indirectly influence growth rates. Growth
beyond what is assumed herein may occur provided the TSOs are met. If there are TSO
violations, or projected TSO violations, in a Tri-Valley jurisdiction, then that jurisdiction
can either (a) implement transportation improvements (e.g., road widening) to correct the
TSO deficiency on that affected network segment, or (b) implement other measures
intended to result in measurable improvements to TSOs on the Routes of Regional
Significance network and contribute to significant improvements in air quality. Failing
this, the jurisdiction can refer the problem to the TVTC for joint resolution. In the event
that the TVTC cannot resolve the violation to the mutual satisfaction of all members, the
jurisdiction may modify the TSO standard, but only if other jurisdictions are not physical-
ly impacted.
Action Plans in Contra Costa County are required to include the following components:
• Long-range assumptions regarding future land use based on local General Plans.
• Procedure for review of impacts resulting from proposed local General Plan amend-
ments that have the potential to influence the effectiveness of adopted Action Plans.
The following are requirements for a Contra Costa County jurisdiction to be considered in
compliance in relation to Regional Routes:
w
Barton-Aschman Associates, inc. xiii
Executive Summary
Submission to Regional Committee of proposed revision(s) to Action Plan to mitigate
impacts associated with proposed General Plan amendments. General Plan amend-
ments that would reduce the effectiveness of adopted Action Plans may lead to a
determination of non-compliance if the Action Plan cannot be revised with the
approval of the Regional Committee and the CCTA.
Financing the Tri-Valley Transportation Plan
The Tri-Valley Transportation Plan was designed to be a feasible, realistic, financially
constrained plan. Still, the plan will require additional funding beyond that provided by
existing sources. Federal and state funds are limited. The Metropolitan Transportation
Commission's (MTC) Regional Transportation Plan (RTP) is used as the source for
estimating future public transportation revenues. Additional funding is suggested through
the adoption of a subregional traffic impact fee on new, unapproved development. The
Plan identifies 11 regional transportation improvements that could be funded through the
impact fee (see Table E-1). Funding these 11 projects, the fee would calculate to about
$2,800 per dwelling unit and $6 per square foot for commercial/office/industrial space.
This discussion is preliminary in nature. The project list, cost estimates, and possible fees
are subject to change pending further discussion at the TVTC and evaluation of the nexus
relationship between new development and its impact on traffic.
Plan Implementation
In order for the Tri-Valley Transportation Plan to be implemented, it must be adopted by
each TVTC member jurisdiction . The following elements should be adopted:
• 2010 Planned Transportation Network
• Transportation Service Objectives
• Action Plans for Routes of Regional Significance (see Chapter 9)
•. Financing Plan
• Subregional Transportation Impact Fee concept

Introduction
The purpose of the Tri-Valley Transportation Plan is to assess transportation issues
within the Tri-Valley area through the year 2010. The study area includes Danville, San
Ramon, Dublin, Pleasanton, Livermore, and unincorporated portions of Contra Costa
County and Alameda County. In addition to serving as a guide for transportation
planning through 2010, this document represents the Action Plan for Routes of Regional
Significance for Contra Costa County jurisdictions, as mandated by Measure C. This
document also provides information that can be incorporated into the Congestion Manage-
ment Programs for Contra Costa and Alameda Counties. This document is in addition to
existing policies, agreements, and regulations that exist in each jurisdiction or between
jurisdictions.
The plan was overseen by the Tri-Valley Transportation Council (TVTC), which includes
elected officials from each of the seven member jurisdictions, under a joint powers
agreement. The TVTC was assisted by the Tri-Valley Technical Advisory Committee
(TVTAC), which includes staff transportation planners and engineers from each agency.
These groups met monthly throughout the plan process, which began in November 1991.
Funding for the Plan came from the Contra Costa Transportation Authority and the three
Alameda Tri-Valley cities.
The plan was prepared using the Tri-Valley Transportation Model (TVTM), which was
developed by Barton-Aschman and TJKM and approved by the TVTC for transportation
planning. The zone structure for the Tri-Valley Transportation Model is compatible with
the Alameda County, Contra Costa County, and MTC transportation models. The model
has been certified by the Metropolitan Transportation Commission, the Contra Costa
Transportation Authority, and the Alameda County Congestion Management Agency.
This transportation plan is intended to fulfill the requirement for preparation of Action
Plans under Measure C in Contra Costa County. Alameda County does not have a similar
Action Plan requirement. Nevertheless, the same plan format is followed for the Alameda

Introduction
County portion of Tri-Valley. The TVTC joint powers agreement states that member
jurisdictions are to consider the Tri-Valley Transportation Plan when adopting or
amending the circulation elements of general plans, specific plans, zoning ordinances, or
capital improvement programs.
The consultant team began meeting with Tri Valley representatives in November, 1991.
Meetings were held once each month with the Tri-Valley Technical Advisory Committee
(TAC). This committee provided guidance to the consultant and reviewed all work
products prior to their submittal to the Tri Valley Technical Council (TVTC). The TVTC
acted as the final approval body for all work completed by the consultant. Meetings -
between the TVTC, TVTAC, and the consultant also occurred on a monthly basis.
Figure 1-1 shows the boundaries of planning areas used to summarize data in this report.
These boundaries have no planning status except within this report, although attempts
have been made to conform to city and sphere of influence boundaries.
Routes of Regional Significance have been adopted by each city in Contra Costa County,
as well as the County, as part of the Measure C Growth Management Program. Routes of
Regional Significance are those roads that serve regional mobility, or act as reliever
routes for the regional system, and serve more than one jurisdiction. The designated
routes are exempt from the Measure C basic route level of service standards. Other
measures, Traffic Service Objectives are to be adopted for these routes. The plan also
includes Routes of Regional Significance for Alameda County, although these are not
mandated by county policy (see Figure 1-2).
Compliance Requirements on Regional Routes
Requirements for compliance with the provisions of the Growth Management Program
relating to Routes of Regional Significance are:
1. Participation in development and adoption of Action Plans: Action Plans will be
developed through the work of the Regional Committees.
2. Implementation of actions designed to attain traffic service objectives consistent with
adopted Action Plan: Action Plans will specify actions to be taken by each jurisdiction.
All localities will agree to the actions before the Plans are finalized and adopted. After
adoption, cities and the county will have an obligation to implement specified actions
consistent with the time frame of the Action Plan.
3. Placing conditions on project approval consistent with Action Plan policies: Some
Action Plan policies may require implementation on an ongoing basis through the
imposition of conditions on development approvals. These might relate to payment of
mitigation fees, implementation of TSM/TDM measures, or phasing of development
relative to infrastructure improvements.

Introduction
Two other regional systems have been designated in the Tri-Valley. These are described
briefly below.
Congestion Management Program (CMP) Routes
These have been designated by Contra Costa County and Alameda County as part of the
state-mandated CMP. In the Tri-Valley, they include only 1-680, 1-580, and Route 84. The
respective county CMP's are shorter-range planning documents than the Tri-Valley
Transportation Plan.
Metropolitan Transportation System (MTS) and
National Highway System (NHS) Routes
The Metropolitan Transportation Commission (MTC) defined a system, called the
Metropolitan Transportation System, in the 1991 Regional Transportation Plan, and the
system has been updated for the 1994 RTP. The purpose of the MTS is to define those
facilities and services that are crucial to freight and passenger mobility in the Bay Area.
The MTS includes streets and highways, transit systems, seaports, airports, truck
terminals, rail yards, and transfer points. In addition to streets and highways, the MTS in
the Tri-Valley includes transit corridors along I-680, I-580, and Route 84; the Altamont
Pass railroad tracks, which continue to Fremont; and the Livermore airport.
The criteria for defining streets and highways in the MTS are as follows:
• Serves a major Bay Area activity center
• Provides important intercounty and/or interregional connections
• Serves as a reliever for a freeway
• Provides important connections in the MTS system
• Serves as a major cross-town arterial for relieving congestion
• Provides access to regional passenger and freight transfer facilities.
Significance of MTS Designation. Roads that are part of the MTS may benefit from
funding available to regional facilities. Any road not in the MTS is considered as serving
primarily local travel.
The National Highway System (NHS). The Intermodal Surface Transportation Efficiency
Act (ISTEA) calls for the U.S. Congress to designate a National Highway System by
December 1995. For the Bay Area, MTC has developed a recommended NHS, which is a
subset of the MTS. The purpose of the NHS is to provide an interconnected system of
principal arterial routes which will serve major population centers, international border
crossings, ports, airports, public transportation facilities, and other intermodal transporta-
tion facilities and other major travel destinations, meet national defense requirements,
and serve interstate and interregional travel. The NHS was proposed to focus federal
funds to improve a limited number of high priority routes.
Barton-Aschman Associates, Inc. 7
Introduction
Figure 1-3 shows the MTS and NHS routes in the Tri-Valley area.
Relationship to County Plans
The Tri-Valley Action Plan will be combined with action plans from the other four
subareas in Contra Costa County to create the Contra Costa Countywide.Comprehensive
Transportation Plan. In Alameda County, a countywide transportation plan was recently
completed. The Tri-Valley Transportation Plan is compatible with the Alameda County
Transportation Plan, although it is more detailed and focused in the Tri-Valley Area. If
adopted, the Tri-Valley Transportation Plan would be incorporated into future-updates of -
the Alameda County Plan.

Existing Transportation Conditions
Chapter Summary
• Tri-Valley is relatively free of congestion. Some occasional congestion occurs on the
freeways, especially near the I-580/1-680 interchange.
Transit usage is relatively low—four percent of total trips.
• Existing average vehicle ridership is about 1.1 for commute trips.
• There are 14,000 more employed residents than jobs, so there is net out-commuting.
• I-680 and I-580 are major regional highways serving substantial regional demand.
Each has 15 to 20 percent through traffic.
This chapter describes the existing transportation systems within the Tri-Valley area,
including the routes of regional significance, the intersection levels of service at major
intersection locations, traffic volumes, transit systems, and bicycle routes serving the
area.
Figure 2-1 shows the number of lanes on the Routes of Regional Significance. Each is
described below.
State Highways
Interstate 580 (I-580) is an eight-lane east/west freeway designated as a route of regional
significance through the Tri-Valley area. Auxiliary lanes exist between Foothill Road and
Santa Rita Road. I-580 is a critical freight route as designated by the Alameda County
CMA. A truck-climbing lane exists in the westbound direction from Foothill Road to the
top of the Dublin grade. Figure 2-1 shows interchange locations.

freeway interchanges such as I-680/Crow Canyon Road and I-580/Dougherty Road/
Hopyard Drive. Table 2-1 compares the volumes to typical capacity ranges. The roads that
are nearing capacity based on ADT are Vasco Road, Vallecitos Road (Highway 84), First
Street in Pleasanton, the two-lane section of San Ramon Valley Boulevard in San Ramon,
Crow Canyon Road near I-680, Hopyard Road north of Owens, San Ramon Road near
I-580, Dougherty Road near I-580, and Dublin Boulevard west of I-680. First Street in
Pleasanton, however, is a downtown street, and congestion in this location is expected due
to the dense development.
Freeway Levels of Service
Level of service descriptions for both I-580 and I-680 were obtained from the I-680
Corridor Study Existing Conditions report prepared by TJE M for the Contra Costa
Transportation Authority and from freeway travel times studies prepared by Abrams
Associates for the Alameda County Congestion Management Agency. These values are
shown on Figure 2-3. The freeway.lane capacity is assumed to be 2,200 vehicles per hour.
I-580 operates at LOS C or better in both directions throughout the Tri-Valley area during
peak hours with the exception of a short segment between the I-580/I-680 interchange and
the Santa Rita Road/Tassajara Road interchange in Pleasanton. This section occasionally
becomes congested during peak hours. I-680 operates at LOS C or better in both direc-
tions throughout most of the Tri-Valley area.
However, a section of northbound I-680 between Stoneridge and the I-680/1-580 inter-
change occasionally becomes congested during peak hours as does the southbound
segment between Alcosta and the I-680/1-580 interchange. All these problems on I-580
and I-680 near the I-680/1-580 interchange are caused by the interchange design with loop
ramps and weaving sections.
The other segments of I-680 that occasionally become congested are from Crow Canyon
Road north to the I-680/24 interchange.
Intersection Levels of Service
The operating conditions at intersections of routes of regional significance and at certain
freeway off-/on-ramps were evaluated with level of service calculations. Level of Service is
a qualitative description of an intersection's operation, ranging from LOS A, or free-flow
conditions with little or no delay time at the intersection, to LOS F, or highly congested
conditions with long delays at the intersection (see Table 2-2).

A signalized intersection's level of service can be calculated with a number of methods.
For this study, a method based on critical movement analysis, called the VCCC method
was used. VCCC stands for Volume-to-Capacity Contra Costa County. See Appendix A for
a full description of the VCCC program. This method is identical to the Circular 212
method except that the saturation flow is increased from 1,500 to 1,800 vehicles per hour.
This adjustment was based on saturation-flow rate studies conducted by CCTA in Contra
Costa County. The volumes of cars on a critical movement are summed and divided by the
capacity of the movement. This V/C ratio of each critical movement at an intersection is
used to produce an overall intersection V/C ratio also taking into account signal phasing.
The overall V/C ratio is then correlated to a level of service (see Table 2-2). AM peak-hour
and PM peak-hour levels of service are shown by city in Table 2-3.
Most intersections of routes of regional significance in the Tri-Valley area operate at
LOS D or better. LOS D is generally considered to be an acceptable operating condition
for major intersections. All but one intersection meet this criteria in the AM peak hour.
The exception is Vasco/I-580 EB Off-Ramp (LOS F). During the PM peak hour three
intersections operate at Level of Service E or F: Vasco/I-580 WB Off, Vasco/I-580 EB Off,
and Danville/Stone Valley.

Tri-Valley Bicycle Network
The bicycle network in Tri-Valley consists of three different types of bicycle facilities:
bicycle paths (Class I), bicycle lanes (Class II), and bicycle routes (Class III). A bicycle
path is an off-street bicycle facility for the exclusive use of bicycles. These facilities are
physically separate from streets or sidewalks. A bicycle lane is a one-way path on the side
of a roadway that is specifically signed and striped for bicycle travel. A bicycle route is a
shared, either with pedestrians on the sidewalk or with vehicles on the street, bicycle
facility on the roadway with no striped designation for bicycle travel.
The majority of bicycle facilities in the Tri-Valley area are Class II and Class III bike-
ways. A few Class I bicycle facilities are available, including the Iron Horse Trail. The
Iron Horse Trail is a mixed-use path for pedestrians, bicycles and horses. This trail runs
along the Southern Pacific right-of-way between Walnut Creek and Dublin. Figure 2-4
shows the existing bicycle network for the Tri-Valley Area and Figure 2-5 shows the
future bicycle network. These networks were defined on the Tri-Valley Bike Plan ap-
proved by the TVTC in February 1992.

Transit
There are several transit options available in the Tri-Valley area. Areawide bus service is
provided by local carriers. Dial-a-ride service is also provided for those transit patrons
that are unable to utilize regular bus service. Transit services provided by larger Tri-
Valley employers augment areawide bus service by either providing special shuttles, as in
the case of Bishop Ranch, or by distributing free transit passes as in the case of Hacienda
Business Park. Connections to other locations in the Bay Area outside of Tri-Valley are
available through the BART Express bus service, which carries patrons to BART stations
in Hayward and Walnut Creek. Connections from Stockton to the Tri-Valley area are also -
available through a bus service provided by the San Joaquin Regional Transit Authority.
Areawide Bus Service
Bus service in the Tri-Valley area is provided by Central Contra Costa Transit Authority
(CCTA), which operates County Connection; Livermore/Amador Valley Transit Authority
(LAVTA), which operates WHEELS; and Bay Area Rapid Transit (BART), which operates
the BART Express Buses. County Connection operates scheduled, fixed-route, and dial-a-
ride bus service in the suburban portions of Contra Costa County. Three routes serve the
Tri-Valley cities of Danville and San Ramon. BART express buses are operated by BART
and provide feeder service between park-n-ride lots, business parks, and BART stations.
BART operates six routes in the Tri-Valley, serving the Bayfair and Walnut Creek BART
stations. WHEELS bus routes, operated_by the Livermore/Amador Valley Transit
Authority, provide scheduled, fixed-route, and dial-a-ride bus services to the Cities of
Dublin, Pleasanton, and Livermore. Pleasanton also provides its own dial-a-ride service.
Table 2-4 briefly describes the bus routes serving the Tri-Valley.
Trip Reduction Programs
The Tri-Valley area includes two major business parks: Bishop Ranch in San Ramon and
Hacienda Business Park in Pleasanton. Both of these parks have implemented innovative
trip reduction programs intended to reduce the number of single-occupant automobiles on
commute routes to these major employment centers. The City of San Ramon oversees the
program in Bishop Ranch.

Existing Transportation Conditions
Bishop Ranch
The Bishop Ranch Business Park operates a shuttle that provides two types of
service—a commuter service and a convenience/shopping service. The commuter
service runs from the.Walnut Creek BART Station to Bishop Ranch. This service is
provided exclusively for employees of tenants of Sunset Development Corporation.
(This service is not available to Chevron, Pacific Bell, or AT&T employees.) This
service operates with 20-minute headways from 5:30 AM to 9:30 AM and from 3:30
PM to 6:10 PM. Average weekday ridership is 250 patrons per day.
The convenience/shopping service runs from Bishop Ranch to Crow Canyon Commons,
Diablo Plaza, and Marketplace Plaza (commercial/retail centers in the area). This
service is provided for employees of tenants of Sunset Development Corporation and
employees of Pacific Bell. This service operates with 10-minute headways from 11:30
AM to 1:30 PM. Average weekday ridership is 40 patrons per day. Both shuttle
services are provided free of charge.
In addition to the shuttle service, Bishop Ranch provides other transportation services.
The transportation center is linked with the RIDES Bay Area ridesharing commuter
network and two full-time employees are available to assist potential carpool/vanpool
riders get matched. Other services provided by Bishop Ranch include the sale of local
transit tickets, promotional events, a preferential parking program, and bicycle
facilities. Bishop Ranch has been offering transportation services for over eight years.
The Bishop Ranch shuttle has operated near or at capacity since it began. Other types
of commute modes are monitored by Bishop Ranch, and percentages of drive-alone
trips have decreased in the past year, while percentages of carpool, vanpool, and other
non-single occupancy vehicle (SOV) trips have increased.
Hacienda Business Park
Hacienda Business Park maintains two transit contracts—one with BART and one
with WHEELS—that allow employees of Hacienda Business Park to ride free.
Participation in the BART program generates approximately 150 patrons per day.
Participation in the WHEELS program runs approximately 160 patrons per day and
has increased by more than 100 percent since 1990, according to John Deaver at the
Hacienda Business Park Owners' Association. Hacienda Business Park also provides to
its employees preferential parking for carpools and vanpools and connections on-site,
through FAX and phone, to the RIDES Bay Area ridesharing commuter network.
Trip Reduction/Travel Demand Management Ordinances
All Tri-Valley cities and counties have trip reduction ordinances in compliance with
CMP requirements and Regulation 13 of the Bay Area Air Quality Management
District. These are targeted at major employers with the intention of reducing peak-
hour trip-making. Many employers have employee commute coordinators, who monitor
Barton-Aschman Associates, Inc. 35
Existing Transportation Conditions
trip-making and encourage alternatives to driving alone during peak hours. Typical
incentives include ridesharing-matching services, preferential parking for carpools, and
flexible or staggered work hours.
Existing Mode Split
The mode split for commute trips in the Tri-Valley area in 1990 was estimated using
the Tri-Valley Transportation Model. The existing estimated mode split is 79 percent _
drive-alone trips, 17 percent carpools, and 4 percent transit trips. This calculates to an
average vehicle ridership of 1.15 persons per car for peak-hour commute trips.
Driveway counts done by the City of Pleasanton in the Hacienda Business Park
indicate an average vehicle occupancy of 1.12, which supports the calculations of the
model.
Existing Travel Patterns
The Tri-Valley presently has about 11,000 more employed residents than local jobs
(see Table 2-5). Hence, it is an area of net out-commuting. However, even areas with a
perfect job-housing balance experience out-commuting by some residents and in-
commuting by others.
Figure 2-6 shows that 58 percent of total PM peak-hour trips in Tri-Valley involve
internal trips, 20 percent are external to internal (out-commuters returning home), 20
percent are internal to external (in-commuters leaving their jobs), and 2 percent are
through trips. "Internal' trips are defined as those with both trip ends in the Tri-
Valley. For persons working in Tri-Valley but living elsewhere the major residence
locations are other Contra Costa County cities and other Alameda County cities. Also,
17 percent live in the Central Valley. For Tri-Valley residents that work elsewhere,
the major destinations are again other Alameda County cities and other Contra Costa
County cities.

Goals and Transportation Service Objectives
Consistent with the Contra Costa and Alameda countywide transportation plans, the
Tri-Valley Transportation Council has adopted the following broad goals to guide this
planning effort.
• Improve safety
• Manage congestion
• Enhance mobility
• Provide and encourage the use of alternatives to single-occupant auto use
• Provide adequate transportation systems to support land use plans
• Integrate transportation planning with concerns relating to air quality, community
character and other environmental factors
• Sustain and support the economic vitality of the region through enhanced
mobility.
According to Action Plan guidelines, these goals are to be achieved through the
specification and monitoring of Transportation Service Objectives (TSOs). TSOs are
quantifiable measures of effectiveness that establish a standard for evaluating
transportation system effectiveness.
No one jurisdiction's actions can assure that traffic service objectives on Regional
Routes will be met. Compliance will be determined on the basis of participation and
implementation of Action Plans. The following are requirements for a jurisdiction to be
considered in compliance in relation to Regional Routes:
• Participation in development and adoption of Action Plans.
• Local implementation of actions designed to attain traffic service objectives consis-
tent with adopted Action Plans.

Goals and Transportation Service Objectives
• Placing conditions on project approvals consistent with Action Plan policies
(e.g., requiring payment of fees or participation in the TSM/TDM program).
• Circulation of environmental documents as specified in Action Plans.
• Submission to Regional Committee of proposed revision(s) to Action Plan to
mitigate impacts associated with proposed General Plan amendments. General
Plan amendments that would reduce the effectiveness of adopted Action Plans
may lead to a determination of non-compliance if the Action Plan cannot be
revised with the approval of the Regional Committee and the CCTA (for Contra
Costa County jurisdictions).
• Participation in Regional Mitigation Programs developed by the CCTA(for Contra
Costa County jurisdictions).
Preliminary TSOs were presented to the Tri-Valley Transportation Council (TVTC) in
February 1993. After discussion and subsequent modification, the TSOs were approved
by the TVTC in March 1993. The following list presents the approved TSOs. One or
more will be applied to each regional route, different routes may have different TSOs.
Link Levels of Service (LOS). Maintain LOS no worse than E (V/C = 0.99) on freeways
and ramps during the peak hours based on traffic counts. This represents a very busy
condition, with speeds about.35 mph on freeways. This standard is sometimes not met
under today's traffic conditions. For freeways, this corresponds to the existing CMP
standards. For arterials, the LOS standard is D on a link basis. These are also subject
to an intersection LOS standard.
Hours of Congestion. Maintain LOS E conditions on I-580 for no more than two hours
in the morning and two hours in the afternoon, except over Altamont Pass, where no
TSO has been adopted. LOS E on I-680 for no more than four hours in the morning
and four hours in the evening. Given the gateway constraints discussed in Chapter 5,
this is the best the plan can achieve.
Intersection Levels of Service. Maintain LOS no worse than D (V/C = 0.90) for signal-
ized intersections during peak hours where the standard is now being met. Achieve
LOS D by 2010 at locations not currently in compliance. The methodology is the VCCC
program, which is based on critical movement analysis, with adjustments to raw
model output turning movements. This is the standard to which all Tri-Valley
jurisdictions presently adhere. Under current conditions, only three of the study
intersections violate this standard.
Tri-Valley Gateways. I-580, I-680, and Crow Canyon Road (Castro Valley to San
Ramon) and Vasco Road (north of Livermore). Maintain existing capacity for single-
occupant passenger vehicles. Widening of gateways would cause the Tri-Valley area to
be negatively affected by interregional traffic. (See Chapter 7 for a complete discussion
of this issue.)

Goals and Transportation Service Objectives
Average Vehicle Ridership (AVR). On average, reduce the number of vehicles used for
commute trips by 2010. This has air quality as well as traffic benefits. The Average
Vehicle Ridership is a measure recommended by the Bay Area Air Quality Manage-
ment District. Their recommended goal is AVR = 1.35 for large employers in the Tri-
Valley by 1999. The current AVR is about 1.15. The transportation service objective is
to increase the overall AVR for all employers, large and small, by 10 percent.
Transit Travel Times. Express transit options should be provided that equal or better
auto travel times in the major corridors (I-680 and I-580) by 2010. Transit travel times -
must be reasonably competitive with auto travel times in order to attract riders.
Transit travel time should be reduced through the provision of more frequent service,
more express service versus local service, with high-occupancy vehicle lanes, and with
ramp metering and HOV bypass lanes.

Baseline Forecasts
Chapter Summary
• Baseline forecasts representing ABAG Projections '90 land use data are required
for Action Plans.
• The baseline forecasts do not reflect current land use or network planning by the
TVTC.
• The planned, baseline transportation system would be inadequate to support the
2010 baseline growth levels.
The baseline traffic forecasts are for the years 2000 and 2010. They are based on land
use projections from the Association of Bay Area Governments (ABAG)Projections '90.
Land use adjustments between individual zones were made to reflect discussions with
local staff. The overall total dwelling units and jobs projections for the Tri-Valley were
not altered. The assumed road network was based on input from the member jurisdic-
tions of the TVTC as of 1992. This chapter describes the model inputs and the traffic
forecasts and their impact on the road system.
Baseline forecasts presented in this chapter are mandated by CCTA and the Alameda
County CMA as part of their planning processes to insure consistency with ABAG
projections throughout the counties. However, the Tri-Valley Transportation Council
(TVTC) believes that the "expected land use" scenario provides a better basis for the
development of the Tri-Valley Transportation Plan recommendations. The TVTC
defined their expectations for land use and network projections, which are presented
in Chapter 5.
Barton-Aschman Associates, Inc. 41
Baseline Forecasts
Land Use Forecasts
The land use forecasts used in the baseline traffic estimates are based on ABAG
Projections '90 (see Table 4-1). Minor modifications were made to the ABAG data to
shift some future houses and jobs between jurisdictions, but the Tri-Valley land use
totals are within one percent of the ABAG forecasts. Note that ABAG forecasts are not
constrained by infrastructure availability or political viability. For comparison
purposes, Exhibit 1 shows a comparison to ABAG Projections '92.
The 2010 land use forecasts do not represent buildout of the Tri-Valley area, as -
specified by each jurisdiction's general plan. Rather, the forecasts represent likely
absorption rates for new houses and businesses between now and 2010.
Network Assumptions
Staff from the Tri-Valley jurisdictions outlined the future road network assumptions
as of 1992 (see Figure 4-1). The major criterion that was considered when including a
particular improvement in the future road network was whether that improvement
was likely to be constructed by 2000 or 2010. Not all of the future road network is
currently funded. This is discussed further in Chapter 7.
The improvements to state highways included in the future road networks were shown
in the MTC 1991 Regional Transportation Plan and are either fully or partially
funded. These include high occupancy vehicle (HOV) lanes on I-680, auxiliary lanes on
I-680, a southbound-to-eastbound flyover ramp at the I-580/1-680 interchange, and
widening of Route 84. Also in the category of regional improvements, the 2010 network
included the extension of BART service to East Dublin/Pleasanton.
The local road Widenings and extensions included in the future networks
g are all
included in local general plans and are all funded or expected to be funded by 2010.
Many are anticipated to be funded with impact fees on new development or will be
built by developers to serve their development projects.

Baseline Forecasts
Traffic Forecasts
The 2010 baseline forecasts show substantial growth in traffic volumes on Tri-Valley
roads. Figure 4-2 shows traffic forecasts for several critical roadways. Plots showing
traffic forecasts for all Tri-Valley roads are included in the Technical Appendix of the
Tri-Valley Transportation Model report (Barton-Aschman Associates, Inc., July 1993).
1 If these traffic increases occur as predicted, without road widenings and additions
beyond the baseline network, severe congestion will result (see Figure 4-3). Congested
locations are defined as freeways with a volume-to-capacity (V/C) ratio of more than
1.0 (volume exceeds capacity) and arterial streets with V/C greater than 0.90 (volume "
equals 90 percent of capacity or more). Figure 4-3 shows that by 2010 almost all
regional routes would be congested.
In many cases the predicted V/C ratio is greater than 1.0. In reality, the volume can
never exceed capacity. However, the traffic model reports demand volume (how many
vehicles would like to use the road in the peak). When V/C ratios greater than 1.0 are
' shown, this means that "peak spreading" would occur. "Peak spreading" means that
congested conditions would last longer than an hour. The effects of peak spreading are
addressed more rigorously in the expected forecasts (Chapter 5).
Intersection Levels of Service
Intersection levels of service (LOS) were calculated using traffic model-generated
turning movements and the VCCC program (see Table 4-2).
Future year lane configurations were based on input from individual jurisdictions. The
intersection analysis included 85 locations. Only two or three intersections are
congested under existing conditions. Congestion is defined as LOS E or F. During the
PM peak hour, the number of congested intersections would rise to 14 by the year
2000 and 36 by the year 2010, according to the baseline forecasts.

Baseline Forecasts
Travel Pattern
The results of the traffic model show that the Tri-Valley will continue to experience out-
commuting and in-commuting. Overall, the baseline forecasts show 18,000 more employed
residents than jobs,,which would reinforce the Tri-Valley's existing pattern of net out-
commuting.
Table 43
Jobs Versus Workers (Baseline Growth Forecasts) _
Year Jobs Workers
1990 111,651 122,882
2000 160,420 167,826
2010 202,887 221,431
Figure 4-4 shows that the traffic model predicts 63 percent of the trips will be internal in
2010, compared to.50 percent today. The other 37 percent of trips will be primarily in-
commuting (16 percent) and out-commuting (18 percent). Only four percent of trips during '
commute hours will be through trips (traffic from other areas passing through the Tri-
Valley). However, this four percent looms large on some parts of the freeway
system. Using the Tri-Valley Transportation Model, 2010 peak-hour through trips were
estimated to range from 15 percent on I-680, to 20 percent on I-580 through Tri-Valley, to
40 percent over the Altamont Pass.
For persons working in the Tri-Valley but living elsewhere, the major residence locations
will be other Contra Costa County cities, other Alameda County cities, and the Central
Valley. For persons living in the Tri-Valley but working elsewhere, the major job locations
will be in other Alameda County cities. To a lesser extent, some will work in other Contra
Costa County cities or in Santa Clara County.
Mode Split
The existing mode split in Tri-Valley involves 4 percent transit use for peak-hour
commute trips, and that is not expected to change in the baseline 2010 forecasts. Ta-
ble 4-4 shows the mode split estimated by the traffic model. The model predicts the drive-
alone percentage to increase slightly. This conclusion is based on MTC-derived assump-
tions about the costs of driving, which are assumed to keep pace with inflation. Transit
and carpool usage are highly dependent on driving costs and travel times. Relative travel
costs and time between drive-alone and other modes are not expected to change through
2010. BART will attract substantial ridership but will not cause,a significant mode shift.

Expected Forecasts
Chapter Summary
• Job and housing growth to the year 2010 is projected to be 99 percent and 84
percent, respectively, which exceeds historical growth trends. Jobs and housing
would be in balance within the Tri-Valley. This would minimize, but not elimi-
nate, in-commuting and out-commuting.
• Highway gateways to the area (I-680 north and south, I-580 over Altamont Pass
and Dublin Grade, Crow Canyon Road to Castro Valley, and Vasco Road) would
have more demand than capacity.
• Unacceptable levels of service would also occur on I-580 between Tassajara Road
and North Livermore Avenue and at 11 signalized intersections.
• Transit mode share would not change appreciably from existing conditions despite
the BART extension.
• Average vehicle ridership would not change appreciably from existing conditions.
• Through traffic on the freeways would remain at 15 to 20 percent.
The baseline forecasts were prepared to satisfy CCTA guidelines, and they are
compatible with ABAG Projections '90. However, there were several jurisdictions
dissatisfied with the land use forecasts, which did not reflect general plan amend-
ments approved after 1992. Also, the 2010 transportation network assumed in the
baseline forecasts.did not reflect current planning. This led to the development of the
"expected" scenario, which reflects each jurisdiction's most accurate prediction of 2010
land use totals and network expectations.
This chapter describes the results of expected traffic forecasts using the Tri-Valley
Traffic Model.
Barton-Aschman Associates, Inc. 63
Expected Forecasts
Land Use Forecasts
The land use forecasts used in the expected traffic projections are based on informa-
tion provided by the member jurisdictions of the TVTC (see Table 5-1). The 2010 land
use forecasts do not,represent buildout of the Tri-Valley area, as speed by the
jurisdiction's general plan, nor do they represent ABAG projections. Rather, the
forecasts represent each jurisdiction's estimate of absorption rates for new houses and
businesses through 2010. Note that the estimates were based on a five percent
vacancy rate.
The "expected" forecasts show an increase in both housing and employment from that
assumed under "baseline" forecasts discussed in the previous chapter. The "baseline"
forecasts assume a 78 percent and 82 percent increase in housing and employment,
respectively, between 1990 and 2010. Under the "expected" forecast, the increase
would be 84 and 99 percent, respectively, which exceeds historic growth trends. The
reason for the increase is that Contra Costa County, Alameda County, Dublin, and
Livermore had passed general plan amendments that were not reflected in the
baseline forecasts.
Overall, "expected" forecasts balance employed residents to employment. 1990 land use
data shows a slight imbalance with 122,882 employed residents and 111,656 jobs. The
"expected" forecasts increase employment at a greater rate than housing resulting in
224,733 employed residents and 222,024 jobs. Note that no adjustments were made to
the forecasts to reflect changes in the absorption rate as a result of higher traffic
impact fees. -
Network Assumptions
Staff from the Tri-Valley jurisdictions outlined the future road network assumptions.
These network assumptions are shown in Table 5-2 and Figure 5-1. The major
criterion that was considered when including a particular improvement in the future
road network was whether that improvement was likely to be constructed by 2010.
Not all of the future road network is currently funded. See Chapter 7 for a further
discussion of the unfunded portions.
The local road widening and extension projects included in the future network are all
included in local general plans and are all funded or expected to be funded by 2010.
Many are expected to be funded with impact fees on new development or will be built
by developers to serve their projects.

Expected Forecasts '
The key transit improvement in the Tri-Valley is the extension of BART to Dub-
lin/Pleasanton with two local stations. Local WHEELS routes will be rerouted to serve
the BART stations and create transit centers with timed transfers between modes.
WHEELS and County Connection routes are also rerouted and augmented to serve
new development areas in the expected network: North Livermore, East Dublin, and
Tassajara Valley.
The expected network also includes nine new express bus routes to connect the Tri-
Valley with portions of Contra Costa County, Alameda County, and Santa Clara
County that are not served by BART. More details regarding the expected transit -
network are included in the Appendix.
Traffic Forecasts
The 2010 expected forecasts show substantial growth in traffic demand on Tri-Valley
roads. If these traffic increases were to occur, severe congestion would result almost
everywhere on the freeway system. Congested locations are defined as freeways with a
volume-to-capacity (V/C) ratio of more than 1.0 (volume exceeds capacity) and arterial
streets with V/C greater than 0.90 (volume equals 90 percent of capacity or more).
Figure 5-2 identifies the unconstrained 2010 link demand on the regional routes.
In many cases the demand-based V/C ratio would be greater than 1.0. This is particu-
larly true at the gateways to the area, including I-680 north of Alamo, I-680 through
Sunol, the Altamont Pass, and Vasco Road. In reality, the volume can never exceed
capacity. However, the traffic model reports demand volume (how many vehicles would
like to use the road in the peak). When V/C ratios greater than 1.0 are shown, this
means that "peak spreading" would occur. "Peak spreading" means that congested
conditions would last longer than an hour. Based on model projections, many roads in
Tri-Valley would be congested for over three hours during the peak period(See
Table 5-3). Peak-spreading diagrams are included in the Appendix. Figure 5-3 shows
an example.

Expected Forecasts
Gateway Constraints ,
The TVTC recognizes that the gateways act as constraint points regulating flow into
and out of the area. Thus, the demand volumes will never actually be reached. Based
on their inability to get through the gateways, motorists will adjust their schedules to
travel outside the peak hour or to carpool or use transit. This adjustment in travel
schedules, which could be reinforced with ramp metering, will be most obvious on the
freeways and at interchanges. At intersections farther from the freeway; we can be
less certain about adjustments to travel behavior. Motorists may adjust their sched-
ules, or they may continue to travel during the peak hour but to a different destina-
tion, or other peak-hour trips may occur to replace the trips displaced by freeway
congestion. Nevertheless, the plan is based on a Tri-Valley Model run in which the
overcapacity gateway trips have been removed from the assigned traffic volumes. This ,
is a major assumption.
TVTC has agreed to treat the Altamont Pass, Vasco Road, Crow Canyon Road to
Castro Valley, Dublin Grade, Sunol Grade, and I-680 north as physical gateways.
It is unrealistic to plan local transportation facilities to accommodate all peak-hour
traffic projected to flow through state highway gateways if this traffic in actuality
cannot get through the gateways. Constrained as well as unconstrained traffic volumes
have been developed for the Tri-Valley network. The constrained traffic volumes back
down the assigned traffic volumes in proportion to the origins and destinations of the
total gateway traffic. PM peak-hour, directional traffic volumes are shown in Fig-
ure 5-2 for "unconstrained" traffic volumes, Figure 5-4 for the subtracted traffic, and
on Figure 5-5 for the "gateway constrained" traffic volumes. The constrained volumes
are considered the baseline volumes. In order to develop rational action plans for local
arterials, both unconstrained and constrained traffic volumes are shown in the plan.
As actual capacities are more nearly reached monitoring of conditions may indicate the
need to reassess and amend the current action plan.
Level of service (LOS) at gateways for the constrained system is viewed to be no more
than 1.0. Volume in excess of 1.0 which is projected is assumed to be spread over
multiple hours of the peak period. The Plan espouses a policy of cooperation with
adjacent jurisdictions to develop facilities management agreements in terms of ramp
metering and freeway surveillance and control, which would fairly apportion available
capacity in such a way that LOS F will be avoided except for unavoidable traffic
incidents which create intermittent blockages of capacity.

Expected Forecasts
Adjusted Forecasts
To plan for the true expected traffic flow, excess gateway trips, beyond design capaci-
ties, were removed from the system. Residual congestion would still occur in some
locations, as listed below (see Figure 5-6 ):
I-680 north of Danville (gateway)
I-680 south of Pleasanton (gateway)
I-580 over Altamont Pass (gateway)
I-580 between Tassajara Road and North Livermore Avenue
Danville Boulevard (gateway)
Vasco Road north of Livermore (gateway)
Camino Tassajara east of Crow Canyon Road
Crow Canyon Road between Castro Valley and San Ramon (gateway)
Crow Canyon Road east of Dougherty
Bollinger Canyon Road east of Alcosta
Tassajara Road near I-580
Fallon Road near I-580
Dublin Boulevard extension between Tassajara and Fallon
Route 84 between I-580 and Jack London
Travel Patterns
With the expected forecasts, Tri-Valley would continue to experience in-commuting
and out-commuting. This would occur even with a jobs/housing balance: 224,733
employed residents and 222,024 jobs. Trips within Tri-Valley would make up 63
percent of the total trips, compared to 50 percent under existing conditions. Out-
commuting and in-commuting would make up 18 percent and 16 percent of the total
trips, respectively. The remaining 4 percent of the trips would be through trips, traffic
' passing through Tri-Valley. This percentage is low overall but would be significant on
the freeway system. I-680 would comprise 15 percent through traffic, and through
traffic on I-580 would vary from 16 percent at Foothill Road to 40 percent over
' Altamont Pass.

Interchange Analysis
The 2010 expected network includes changes to several freeway interchanges. '
Figure 5-7 shows the interchange.configurations for existing and 2010 conditions. The
following three new interchanges will be added to the network:
• I-580/Shaeffer Ranch Road '
• I-580/Isabel (Route 84)
• I-680/West Las Positas
The following 10 interchanges will be reconfigured or expanded:
• I-580/Foothill. Conversion from full cloverleaf to partial cloverleaf design.
• I-5805-680. Addition of a southbound-to-eastbound flyover ramp, addition of hook
ramps to Dublin. .
• I-580/Fallon. Widening of overpass to six lanes. Conversion to partial cloverleaf
design.
• I-580/Portola. Removal of the ramps, will become just an overcrossing. '
• I-580/North Livermore. Conversion from diamond to partial cloverleaf design,
widening of overcrossing,
I-580/First Street. Widening of overcrossing. '
• I-580/Vasco. Widening of overcrossing, reconstruction of ramps to a partial
cloverleaf design.
• I-580/Greenville. Conversion from hook ramps to partial cloverleaf design.
• I-680/Sycamore Valley. Elimination of the northbound-to-westbound off-loop. '
• I-680/Alcosta. Addition of hook ramps to San Ramon Valley Boulevard, removal of
southbound off-ramp.
• I-680/Bernal. Conversion to standard partial cloverleaf design. '
Tables 5-5 through 5-8 show the 2010 expected volume on the overcrossing and ramps
at each interchange for the PM peak hour. The tables also show the number of lanes ,
required to accommodate the expected volume. In all cases, the existing or planned
interchange configuration will be adequate.

Expected Forecasts
Transit Ridership
The existing mode split,in Tri-Valley involves 4 percent transit use for peak-hour
commute trips, and this is expected to increase to 5 percent for the expected 2010
forecasts. Nevertheless, the drive-alone percentage is predicted to increase slightly
from 76 percent to 80 percent.
The.traffic model estimates transit and carpool usage by taking into account travel
time, travel cost, and transit availability. The model does not include policy direction
that might lead to more carpooling or transit ridership—for example, the Bay Area Air
Quality Management District goals to increase average vehicle ridership. Table 5-9
summarizes the transit ridership forecast for the expected transit network. Transit
ridership is predicted by the Tri-Valley Transportation Model to almost triple by 2010,
compared to a doubling of population and employment. The drive-alone percentage is
expected to remain high, however. This is a function of time and cost factors, which
will continue to favor driving alone. A complete breakdown of transit information for
the "expected" 2010 forecast is included in the Appendix.

Plan Alternatives
Chapter Summary
' The Transportation Service Objective of Level of Service E for the freeways cannot
P J
be met at the gateways based on demand, without spending over $2 billion on
' transportation improvments—far in excess of the funding that could reasonably be
available.
' Even if there were no further development in the Tri-Valley, the freeway system
would still become increasingly congested by long-distance commuters that neither
live nor work in the Tri-Valley. (This assumes that neighboring communities will
' continue to grow as planned.)
• The plan should restrict increases in gateway capacity for single-occupant vehicles,
' insure that the internal transportation system operates at acceptable levels of
service through selective network improvements and freeway ramp metering, and
achieve a jobs-housing balance. Ridesharing and transit usage should be particu-
larly emphasized at the gateways.
This chapter describes the alternatives tested to develop the Tri-Valley Transportation
' Plan. Potential actions and strategies to address the projected transportation deficien-
cies were developed by the consultant, the TAC and the TVTC. These actions and
strategies can generally be divided into three groups: increase transportation supply
' through highway investment, increase transportation system efficiency through more
reliance on transit, and decrease transportation demand through land use adjust-
ments. Note that the evaluation of transportation alternatives was conducted with the
baseline forecasts and did not include the gateway constraint concept.

Plan Alternatives ,
Maximum Highway Investment
The-purpose of testing an alternative that maximized highway investment was to see '
if, regardless of cost, it would be possible.for the Tri-Valley to build its way out of the
problem of traffic congestion. All physically and potentially politically acceptable road
improvements were included. The assumed maximum highway network changes are
shown on Figure 6-1. Expenditures for these improvements are summarized, by ,
improvement, in Table 6-1. Funding levels for the maximum highway investment
would require an additional $598 million beyond that required for the assumed
baseline improvements. Approximately $547 million of this amount would be '
unfunded.
These changes included substantial capital expenditures on new roads and road '
widening projects throughout the Tri Valley area. The additional road capacity would
alleviate, to some degree, congestion on arterial corridors in Tri Valley. The gateways
to Tri Valley (I-680, Altamont Pass and Vasco Road) would continue to be congested '
during peak conditions. Figure 6-2 shows the congested routes with the maximum
highway alternative.
Maximum Transit Investment
This alternative was to test the ability of transit systems to relieve highway conges-
tion. Transit systems offering travel times superior to automobiles were included in
the major corridors.Potential transit improvements are shown on Figures 6-3 and 6-4.
Cost estimates for the maximum transit investment is summarized in Table 6-2. The ,
maximum transit investment would require an additional $1.136 billion in capital and
operating costs through 2010 beyond the baseline improvements. None of this amount '
is funded.
Potential projects include BART service extended to Eastern Livermore, Altamont ,
Pass Rail service from Stockton to San Jose, and north/south corridor priority express
bus transit. Extensive bus service feeding the proposed rail stations was also assumed.
The additional system capacity would not eliminate congestion on either arterial
corridors or the gateways to Tri-Valley (I-680, Altamont Pass and Vasco Road). '
Figure 6-5 shows the congested routes with the maximum transit alternative.

-Plan Alternatives
land Use Opportunities
Given the high cost, limited availability of funds, and lack of overall system improve-
ment for either a maximum highway or maximum transit network, the consultant was
instructed by the TVTC to test modifications to proposed land uses.
A real estate economics firm, Economic & Planning Systems (EPS), was contracted to
prepare a study of how a reduced land use plan might be structured. Their complete
land use study is included in the Appendix. They prepared the following list of criteria
for structuring the reduced growth plan.
Criteria for Developing Managed Growth Land Use Scenario
1. Determine Traffic Analysis Zones (TAZs) that are the significant contributions to
traffic congestion (producing trips in excess of network link capacity).
2. Identify TAZs where residential and employment density could be increased where
access to transit is high (transit-oriented development).
3. Identify TAZs where infrastructure capacity (e.g., arterial roadways) exists that
can support higher density residential and employment mixed-use development.
4. Reduce proposed residential.density in TAZs with limited or nonexistent network
and poor transit service potential.
i, 5. Reduce employment land use designations and/or proposed capacity in areas with
limited road network and transit access, undeveloped or underdeveloped backbone
infrastructure, or weak market demand.
"
6. Construct a Managed Growth Scenario by redistributing and reducing 2010
Expected Growth to achieve.a level of service policy on Baseline Network.
EPS used these criteria to develop specific reduced-growth recommendations (see
Table 6-3). These recommendations were considered but not adopted by the TVTC.
Several land use reduction treatments were tested with the traffic model. None
produced satisfactory results with respect to eliminating overcapacity demand on the
freeway system. As a worst-case test, the consultant tested an alternative with zero
growth through 2010 in the Tri-Valley while allowing growth to occur as predicted in
neighboring communities. Through this evaluation, it was determined that congestion
at the gateways (I-680, Altamont Pass, and Vasco Road) would not be influenced by
Tri Valley growth but rather growth in neighboring communities. In other words,
there is no way to control the freeway system demand by only adjusting growth within
Tri Valley. Figure 6-6 shows the congested links with the zero growth alternative. The
lack of local control over freeway volumes at the gateways, as evidenced by the zero
growth alternatives, lead to the policy of gateway constraints. This is discussed further
in Chapter 7.

Plan Alternatives
The reduced growth scenario was shown, however, to have a profound effect on traffic
levels on the arterial system. The TAC concluded that congestion on the arterial
system could be controlled through growth management, even though congestion on
the freeway system could.not..
Plan Evolution
The TVTAC outlined four alternatives for consideration by the TVTC (see Table 6-4).
These were combinations of various elements discussed and tested throughout the
plan evolution.
These four alternatives were presented to the individual councils of each city and the
boards of the two counties. These elected representatives provided input as to which
plan elements should be pursued further. Table 6-5 shows the composite of positions
taken by each body. The TVTAC interpretation of the policy direction was as follows:
1. Road Improvements. Pursue the maximum amount of improvement P p ovement within the
limits of physical feasibility, but keep the regional impact fee within the $1,000-
$2,000 per dwelling unit range. This was thought to be the highest politically
feasible subregional traffic impact fee.
2. Transit Improvements. Provide transit options in the well-travelled corridors, but
recognize that transit cannot carry a significant mode share given the suburban
land use pattern of the area.
3. Higher Densities. The benefit of higher densities from a transportation perspective
is that transit can be a more effective alternative to driving. There was some
interest in changing development patterns to increase overall densities, especially
in transit corridors. Recently approved specific plans for East Dublin and North
Livermore create some higher-density areas. Densities necessary to support
significant transit usage need to be at least 15 dwelling units per acre.
4. Growth Management. The TVTC agreed to proceed with a specific growth man-
agement study to resolve projected TSO deficiencies at 11 intersections and to
define equitable sharing of the burden.
5. Reduced LOS Standards. These were considered only for the freeway system in
locations where through traffic made achievement of TSOs impossible for the
TVTC to achieve. While demand volumes could not be accommodated, ramp
metering would allow achievement of CMP-mandated levels of service on the
freeways.
6. TDM Measures. The need for realistically achievable ridesharing goals was
recognized. However, the TVTC is not in favor of simply assuming away problems.
They also are not in favor of aggressive programs such as paid parking.

Recommended Improvement Plan
Based on the results of the alternatives testing, the TAC and the TVTC decided to
focus the ultimate improvement plan on the arterial corridors within Tri-Valley rather
than the Tri-Valley gateways. The plan must address the primary question: What can
we do to achieve.the best level of service within the Tri-Valley?
Three contributing factors influence the ability to respond to this question.
• Financial constraints.
• Physical limitations within corridors.
• Development pattern.
Financial resources for all projects are limited. The Measure C and Measure B sales
tax programs provide substantial funding for specific projects in Tri-Valley. Other
projects must compete for the relatively small pot of public funds. Developer fees,
which have an upper limit, could help supplement public funds. Future sales tax or
gasoline tax initiatives may or may not be successful.
Expansion of major corridors within Tri-Valley is limited due to existing development
and terrain. These. limitations hinder the development of transportation corridors
other than the existing I-680 and I-580 corridors.
Development patterns within Tri-Valley have been geared toward relatively low
housing and commercial densities. These patterns are expected to continue in the
future. This development pattern is impossible to serve thoroughly with transit, given
realistic funding expectations.
Barton-Aschman Associates, Inc. 122
Recommended Improvement Plan
Plan Overview
The TVTAC used the policy direction to create a set of actions comprising an integrat-
ed plan. The transportation plan comprises enhancement to roadway capacity coupled
with increased transit service, control of demand (growth management and TDM), and
acceptance of congestion in locations where it cannot be avoided. The plan is financial-
ly constrained in that it includes only elements that are already funded, likely to be
funded given extension of federal and state programs, or fundable by new development
at an affordable level. Chapter 8 describes the financing plan.
The following sections provide an overview of the plan.
Rood Improvements
The plan includes many improvement projects for freeways, interchanges, arterials,
and intersections. These are all based on the reality of gateway constraints.
Gateway Constraints. Analysis of alternatives through the planning process showed
' that the TVTC's best interests would not be served by widening any of the gateways
for single-occupant vehicles leading into the area. The gateways include I-680 north
and south, I-580 east and west, Crow Canyon Road to Castro Valley, and Vasco Road.
1 Widening of these gateways would still leave the freeways congested, would lead to
more through traffic, and would increase traffic volumes on other Tri-Valley roads.
This is true because of the Tri-Valley's strategic location between San Joaquin County
and the Bay Area and also between Central and Eastern Contra Costa County and
Santa Clara County.
The implication of gateway constraints for roadway planning is that the interior
freeways and arterials should be sized to handle only what traffic can get through the
gateways. Thus, the plan recognizes that congestion will occur for several hours each
weekday at the gateways, but this will have the positive effect of metering single=
occupant vehicle travel to and from the area. Within the Tri-Valley area, the road
system is designed to minimize congestion. While not ideal (the ideal would be to have
no congestion anywhere), the roadway plan when combined with a balance between
jobs and housing, produces the best conditions to be reasonably expected.
The reasons behind the gateway constraint concept are different for different gate-
ways, as discussed below:
I-680 North. The section north of Diablo Road cannot practically be widened
beyond the HOV lanes under construction. The gateway constraint assumption
recognizes this reality.
I-680 South. The section south of Route 84 has room to be widened, and limited
widening would support the investment in Route 84 capacity. Accordingly, the
plan recommends the addition of HOV lanes (see Chapter 7). Gateway constraints
would still apply for single-occupant vehicles.
Barton-Aschman Associates, Inc. 123
Recommended Improvement Plan
I-580 West. This section between Tri-Valley and Castro Valley has a projected
demand of 10,300 vehicles eastbound in the PM peak hour. Widening beyond the
current four lanes is infeasible.
I-580 East (Altamont Pass):_Alameda County policy, in recognition of the need to
encourage shorter commuter and not overload Tri-Valley roads with regional
traffic, opposes increases to capacity for single-occupant vehicles. Therefore,
gateway constraint is warranted. The plan includes HOV lanes, as a second
priority project, in recognition of the importance of I-580 as a regional facility (see
Chapter 7). The gateway constraint policy also applies to Patterson Road, Tesla
Road, and Old Altamont Road.
Crow Canyon Road (to Castro Valley). Safety improvements are planned for this
section of Crow Canyon Road. However, the TVTC supports maintaining the two-
lane cross-section.
Vasco Road. Vasco Road is planned for implementation as a two-lane road.
However, the two-lane road project should be done in such a manner to not
preclude future accommodation of public transit or other improvements as subse-
quently determined appropriate.
The Plan is based upon the following set of assumptions regarding gateway capacity
on the freeways and major arterials which access the Tri-Valley:
I-680 to the north. Six lanes plus HOV lanes.
• I-580. Eight lanes.
• I-680 to the south. Six lanes plus HOV lanes.
• Crow Canyon Road to Castro Valley. Two lanes.
• Vasco Road north of I-580. Two lanes.
Any departure from these assumptions would required amending the Plan.
The TVTP/AP, by incorporating a gateway constraint methodology, is breaking new
ground. Action Plans being prepared for adjacent subareas in Contra Costa County
have not employed this methodology. Consequently, the use of the gateway constraint
methodology could raise a consistency issue between the TVTP/AP and adjacent Action
Plans in Central, East, and Southwest Contra Costa County. Furthermore, no formal-
ized approach for conducting the gateway constraint method of analysis has been
adopted by either the Alameda or Contra Costa CMAs. The Contra Costa Transporta-
tion Authority's Technical Procedures is reticent on the gateway constraint
methodology.
Current gateways are established by two factors: geographic constraints and financial
constraints. To some degree the geographic constraints can be overcome through
significant capital investments in new highway projects. However, the Tri-Valley
Transportation Plan is based upon the assumption that significant capacity enhance-
-
Barton-Aschman Associates, Inc. 124
Recommended Improvement Plan
rments to the gateways serving Tri-Valley are financially infeasible. The Policy of the
Tri-Valley Transportation Council is to work closely with neighboring jurisdictions,
Congestion Management Agencies, Caltrans, and MTC to resolve capacity problems at
the gateways and as needed through the partnership activities and to subsequently
adjust our Transportation Plan should funding of mutual acceptable facilities become
possible.
Freeway Ramp Metering. Ramp metering is a way of controlling the volume of traffic
entering a freeway so the system is as efficient as possible. A survey made for the
Federal Highway Administration of seven ramp metering systems in the United States
and Canada revealed that average highway speeds increased by 29 percent after
installing ramp metering and travel times decreased 16.5 percent. At the same time
reductions of freeway congestion averaged approximately 60 percent. An analysis of
the FLOW system in Seattle (ramp metering and HOV lanes) revealed that in addition
to similar improvements in speed and travel time, highway throughput increased from
12 to 40 percent as a result of ramp metering. An additional benefit from ramp
metering is a decrease in the accident rate. Reductions from 20 to 58 percent have
been achieved through improved merging operations.
Without ramp metering, bottlenecks will develop on the freeway that decrease
throughput and lead to longer delays than motorists face at the meters themselves.
1 Ramp meters also encourage the peak spreading that needs to occur to keep the
gateways flowing. This happens.because motorists are willing to accept only up to
about a 10-minute wait at the meters. Beyond that, they will adjust their trip-making
(i.e., choose to travel at a different time or choose a different mode). This peak
spreading helps to get the most out of the system when gateway constraints are a
reality.
Without ramp metering it is projected that the freeway flow will break down and be
congested for long periods of time with the on-ramps not being able to flow at their
designed flow rates. The on-ramps will be metered by freeway congestion rather than
planned rates. Staff believes a metered system will move more people more effectively
and equitably than an unmanaged system. The unmetered system is also more prone
to be blocked by congestion-induced accidents than a metered system.
An additional major benefit of ramp metering is that it can be combined with HOV
bypass to provide an additional powerful incentive for carpooling and can help buses
increase average speeds. When combined with HOV lanes on the freeways, the ramp
metering-with-bypass system allows carpools and buses to travel unimpeded through-
out the system.
Ramp metering has two potential drawbacks: backups on the local street system, and
rewarding long-distance commuters. The potential for backups on local streets can be
minimized through ramp widening and strategic placement of the meters. The risk of
rewarding long-distance commutes can be minimized by instituting a system of ramp
metering for the entire length of a freeway, rather than in isolated locations.
1 Barton-Aschman Associates, Inc. 125
Recommended.Improvement Plan
The Tri-Valley Transportation Plan includes ramp metering with HOV bypass with
the proviso that this not seriously impact local streets and that local implementation
be tied with implementation along all of I-680 and I-580 in neighboring communities.
Freeway HOV Lanes. High Occupancy Vehicle (HOV) lanes are under construction
.. g p y
along I-680 between Rudgear Road and I-580. HOV lanes provide the advantage of
reducing travel times for ridesharers and transit patrons. They also enhance mobility
during off-peak hours by being available for all vehicles. This is especially important
when considering truck traffic, which increasingly relies on off-peak hours to reach
destinations without undue delays.
The TVTC recognizes the benefits of HOV lanes, but realizes that take-a-lane pro-
grams do not work. Such an ill-fated attempt at providing HOV lanes on I-580
resulted in federal legislation prohibiting their use on that freeway in unincorporated
areas. Thus, HOV lanes must be added to the freeways.
HOV lanes on both I-680 and I-580 are included in the plan. Due to the expense of the
projects, however, some segments are included as lower priority projects. I-680 south
of I-580 has been designed to accommodate the addition of HOV lanes, but pavement
widening would be required. Top funding priority should be given to the section south
of Route 84 to the top of the Sunol Grade, which is the border of Area 4 in the
Alameda Countywide Transportation Plan. This section will experience significant
traffic increases due to the planned capacity increases to Route 84. The section of
I-680 between Alcosta Boulevard and Route 84 should also be planned to include. HOV
lanes but with a lower funding priority.
H lanes would be more difficult and costly to build because the inter-
On I-580, OV a o y e
changes have not been built to accommodate them. However, the Caltrans Route
Concept calls for 10 lanes plus BART in the median for I-580. The most important
segment for funding priority on I-580 is the segment between Tassajara Road and
North Livermore-Avenue. This segment is predicted to experience the highest traffic
demand along I-580 in the Tri-Valley. To accommodate the extra freeway width, the
interchanges at El Charro/Fallon and Airway would need to be rebuilt. The El Charro/ .
Fallon interchange is planned to be rebuilt anyway. In addition, the planned new
interchange at Isabel Avenue (Route 84) would need to be built to accommodate the
width. As a lower funding priority, the plan also includes extending the I-580 HOV
lanes east to the Alameda County border. This would require widening four
interchanges in Livermore (N. Livermore, First, Vasco, and Greenville), and three
interchanges/crossings east of Livermore.
Extending HOV lanes on I-580 west of Santa Rita Road is more problematic. With the
BART extension and the I-580/1-680 interchange project, this section will be built out
to its full Route Concept width of 10 lanes plus BART. The section will have four
through lanes, as it does today, plus auxiliary lanes between interchanges. Thus, HOV
lanes on I-580 west of Santa Rita are not included in the plan.

' Arterial Issues: The planned arterial system has been designed to provide smooth
circulation in and between the Tri-Valley cities and to provide access to the
freeway system. Intersections and freeway interchanges are the focal points of the
arterial system. All of the widenings and extensions are necessary to serve new
development, so the plan calls for direct developer construction or at least funding.
The primary issue is how to share costs between jurisdictions having joint respon-
sibility for a particular road. This is discussed further in the Financing Plan
chapter.
There are two major arterials in the Tri-Valley that do not provide direct access to
planned development but rather serve interregional traffic between Alameda
County and Contra Costa County. These two arterials are Crow Canyon Road and
Vasco Road.
Crow Canyon Road. The portion of Crow Canyon Road west of Bollinger Canyon
Road is a two-lane rural road that lies within the jurisdiction of Alameda County
and Contra Costa County. While once used by its adjacent residents to bring goods
to the market, today, Crow Canyon Road is being used by commuters as an
alternate route to the I-580/1-680 freeways. Development in the vicinity of Crow
Canyon Road, especially in the fast-growing San Ramon Valley area, has generat-
ed a significant increase in traffic on this roadway. The expected forecast for this
roadway is LOS F.
The roadway, which is a narrow and winding road, was not designed to handle
commuter traffic and does not have adequate width and alignment. The Alameda
County, in collaboration with Contra Costa County and the City of San Ramon
prepared and developed a project study report,pursuant to California Senate
Bill 1149. The report recommended the construction of eight-foot shoulders,
climbing lanes and road realignment eliminating short-radii curves.
Contra Costa County has in its Measure C program the improvement of Crow
Canyon Road within Contra Costa County. Alameda County, however, is seeking
for funds to improve the two-lane section of the roadway. Unfortunately, improve-
ment of this portion of Crow Canyon Road cannot be directed to a particular
developer construction. But since the traffic forecast clearly indicates that traffic
increase on this roadway is development related, it is recommended that
subregional transportation impact fees be used to improve the section of Crow
Canyon Road within the Tri-Valley area.
Vasco Road. Vasco Road is a narrow and winding rural road that is a major
commuter and truck route linking the Tri-Valley with eastern Contra Costa
County. Approximately 17 miles of Vasco Road, starting at a point on Vasco Road
approximately one-half mile south of the County Line to the intersection of
1 Camino Diablo in Contra Costa County, will be relocated as a result of the
construction of the Los Vaqueros Reservoir. This portion of Vasco Road is designed
as a two-lane highway based on state and county standards for new roads with
comfortable speeds of up to 65 mph. Meanwhile, the remaining section of the
' Barton-Aschman Associates, Inc. 127
Recommended Improvement Plan
roadway in Alameda County(approximately three miles in length) has tight
curves and narrow shoulders with advisory speeds along curves of less than 35
_mph. Vasco Road is expected to have a Level of Service F in the year 2010.
Plan ll' for policy limiting the capacity of Vasco Road to two ,
As much as the Pla calls p y g p y
lanes, it is necessary that this roadway be realigned to improve traffic flow and
safety. Alameda County is currently seeking funds to improve the section of the
roadway from the new Vasco Road to the Livermore City Limit. This proposed
improvement includes realignment of the roadway, widening of shoulders,a nd
installing passing lanes without increasing its capacity, consistent with the
standards being used in the Los Vaqueros-Vasco Road project.
Projected congestion on this roadway cannot be directed to a particular develop-
ment but its future congestion is truly the result of developments in the region. It
is also recommended that subregional traffic mitigation fees be used to improve
this facility.
Transit Improvements
The key transit improvement in the Tri-Valley is the extension of BART to Dub-
lin/Pleasanton with two local stations. Local WHEELS routes will be rerouted to serve
the BART stations and create transit centers with timed transfers between modes.
WHEELS and County Connection routes will also need to be rerouted and augmented �.
to serve new development areas: North Livermore, East Dublin, and Dougherty Valley.
In addition, nine new express bus routes are included in the plan to serve the follow-
ing corridors not served by BART: I-680 north to Walnut Creek, Vasco Road to East
County, and I-680 south to Fremont.
The Tri-Valley Transit Plan has been developed to correspond to expected funding
levels. Since the area is expected to almost double in population, the assumption is
that transit funding will also double. It is important to note that this assumption may
not be realized. Transit funding may not keep pace with population increase. Never-
theless, the plan includes the provision for significant new services plus greater use of
existing routes that have available capacity. Additional riders can be served without
additional investment.
Note, however, that the development pattern in the Tri-Valley is one of overall low
density, and the new areas proposed for development will generally reinforce the low-
density pattern. The low-density pattern does not support the extensive use of transit
or cost-effective transit operations. If transit is to serve a much greater role than it
does today, development densities will need to increase.
Growth Management
The TVTC recognizes that its mission is not to plan land use. Land use inputs to the
plan came from the planning department of each member jurisdiction. Projections are
also available from ABAG, and the "expected" land use on which the plan is based is
Barton-Aschman Associates, Inc. 128
Recommended Improvement Plan
' 11,000 dwelling units higher than Projections '92 for the Tri-Valley as a whole. Action
Plans in Contra Costa County are mandated by Measure C to address growth manage-
ment issues when TSOs cannot otherwise be met. CCTA guidelines for Action Plans
state that they may include policies to prohibit urban expansion in specified geograph-
ic areas and to change the distribution of planned land uses to reduce impacts on
regional routes. It should be noted that the TVTP is a 2010 plan and land use
recommendations apply to 2010 and not buildout.
Action Plans in Contra Costa County are required to include the following components:
•
Long-range assumptions regarding future land use based on local General Plans.
g P
• Procedure for review of impacts resulting from proposed local General Plan
' amendments that have the potential to influence the effectiveness of adopted
Action Plans.
The following are requirements for a Contra Costa County jurisdiction to be considered
in compliance in relation to Regional Routes:
• Submission to Regional Committee of proposed revision(s) to Action Plan to
.mitigate impacts associated with proposed General Plan amendments. General
Plan amendments that would reduce the effectiveness of adopted Action Plans
may lead to a determination of non-compliance if the Action Plan cannot be
revised with the approval of the Regional Committee and the CCTA.
�[ Contra Costa County Action Plans may include the following types of actions:
�j Land Use Policy
1. Modify allowable densities for newly developing areas or areas where redevelop-
ment is anticipated.
D2. Change distribution of planned land uses (new or redeveloped) to reduce impacts
on Regional Routes.
a3. Prohibit urban expansion in specified geographic areas.
O 4. Condition development approvals on progress in attaining traffic service
objectives.

General Plan Amendments in Contra Costa County
1
The tools and procedures for conducting General Plan updates and analyzing proposed t
General Plan amendments will be the same as those used in preparing the Growth
Management Elements. If the specific project or policy changes are large enough to
meet requirements established by the region in its adopted Action Plan, the jurisdic-
tion considering the Plan amendment must submit the amendment the Regional
Committee for evaluation of its impact on the ability to achieve Action Plan objectives.
The Growth Management Program directs the RTPCs to evaluate proposed amend-
ments only in relation to issues affecting Action Plan success and consistency. It will
be the responsibility of the jurisdiction considering the amendment to either:
1. Demonstrate that the amendment will not violate Action Plan policies or the
ability to meet Action Plan Traffic Service Objectives; or
2. Propose modification to the Action Plan that will prevent the General Plan amend-
ment from adversely affecting the regional transportation network.
If neither of these can be done, approval of the General Plan amendment may lead to
a findings of non-compliance with the Growth Management Program.
i
General Plan Consistency with Contra Costa County Action Plans
The Action Plans for Routes of Regional Significance will be based upon adopted ,
General Plan land uses, the existing road network, and planned improvements to the
network. Consistency with the Action Plans must be established for any changes to the
Barton-Aschman Associates, Inc. 130
' Recommended Improvement Plan
General Plan that may significantly reduce the ability of the facility to meet the
Traffic Service Objectives. The RTPC will be responsible for establishing the type and
size of amendment that will require review by the RTPC and the process for imple-
menting this review. Approval of a General Plan Amendment found to be inconsistent
with the adopted Action Plans may render the jurisdiction ineligible for Local Street
Maintenance Improvement Funds from the CCTA.
Consistency with the Action Plans can be achieved by revising the proposed amend-
ment, adopting local actions to offset impacts to the Route of Regional Significance, or
Council or Board denial of the amendment.
Jurisdictions in Tri-Valley may implement a proactive Growth and Congestion
Management strategy once a detailed growth management study has been conducted.
The study should indicate the development reductions, land use density reductions, or
other types of growth management/control that would be required for each applicable
Tri-Valley jurisdiction in order to achieve TSO standards. Any development reduction
should be proportional to the traffic distribution percentages for each jurisdiction.
Also, the impact of this development reduction to traffic impact fees should be
analyzed. All jurisdictions will then review this information and know exactly how
much reduction in development or growth management/control is needed to meet the
TSOs.
Jobs-Housing Balance
Another aspect of land use growth relevant to transportation planning is jobs-housing
balance. The Tri-Valley now has more housing than jobs. The 2010 expected land use
scenario includes more job growth than housing growth, which will establish a
balance. Because of the dynamics of the Bay Area, in-commuting and out-commuting
will still occur, but at least they are reduced with a jobs-housing balance in the Tri-
Valley.
The importance of a jobs-housing balance is further reinforced by the gateway
constraints that will exist in the Tri-Valley area. Trip-making into and out of the area
will become increasingly difficult in the future. The provision of a job for every
employed resident and vice versa will minimize the need for residents to leave the
!1 area for work. This will minimize the traffic pressure at the gateways.
a An important issue to remember with regard to jobs-housing balance is that the
numerical count alone is insufficient to achieve the desired result of minimizing travel.
The housing must be of a variety to be affordable to each income level.
Reduced Level of Service Standards
O The TVTC has seen that the originally intended transportation service objective of
LOS E on the freeways based on demand cannot be met in many locations regardless
of land use assumptions. In fact, this standard cannot even be met with today's
Ovolumes. This is true because growth in San Joaquin County, Santa Clara County, and
Barton-Aschman Associates, Inc. 131
:Recommended_Improvement Plan ,
Central and East Contra Costa County will fill up the Tri-Valley freeways even if Tri-
Valley jurisdictions do not grow. Therefore, the TVTC will accept congestion at the
gateways recognizing that while it is not ideal, at least it will minimize through
traffic. The focus then,shifts to maintaining adequate levels of service, and providing ,
transit options, for trips within the Tri-Valley.
The transportation plan succeeds in avoiding congestion on the arterial system. Also,
I-680 between Alamo and Route 84 is expected to flow smoothly. Level of Service F
conditions, however, are expected on I-580 westbound in the morning and eastbound
in the evening between Tassajara Road and North Livermore Avenue. This would be
partially alleviated with high occupancy vehicle lanes and ramp metering.
Transportation Demand Management (TDM)
The TVTC supports TDM measures; however, TVTC does not want to base the
Transportation Plan on unrealistic TDM goals without supporting programs. Through
the plan process, the Bay Area Air Quality Management District (BAAQMD)-mandat-
ed average vehicle ridership (AVR) of 1.35 was tested. This applies to employers with
100 or more employees. The TVTC estimated that such large employers make up only ,
about 10 percent of all employment. This, coupled with the fact that commute trips
make up about 35 percent to 40 percent of the PM peak-hour traffic stream, means
that the BAAQMD mandate will have negligible impact on traffic levels.
The TVTC also investigated the impact of achieving an AVR of 1.35 for all employers,
throughout the Bay Area, large and small. Compared to the "ambient" AVR of 1.10-
1.15, this would be a 20 percent improvement. Given the commute trip proportion of
total PM peak-hour traffic, a 20 percent increase in AVR would translate into 7
percent to 8 percent less traffic on the roads. While this would create a significant
improvement in operations, it would not significantly reduce the need for road
building. Nevertheless, if at least a 10 percent increase in AVR were not achieved,
additional intersection improvements, beyond what are included in the plan, would
probably be necessary.
The achievement of a 20 percent increase in AVR would not be easy. The TVTC
believes that this would require a significant increase in the cost of solo commuting.
However, the TVTC is not in favor of parking charges. Gasoline tax increases would be
more acceptable, provided they were levied regionwide (including.San Joaquin
County). Gas tax increases would encourage commute alternatives and would provide
more money for transportation investments.
The plan is based on a more-achievable goal of an average 10 percent increase in AVR
for all employers. This increase would be realized through the adoption and enforce-
ment of local trip reduction ordinances. The 10 percent increase in AVR will bring
some of the intersections otherwise projected to be borderline unacceptable back into ,
compliance with the TSOs.

Recommended Improvement Plan
Road Improvement Plan
The Tri-Valley Transportation Plan includes many road improvement projects. These
r projects were developed by the'member jurisdictions of the TVTC. Projects range from
intersection modifications to freeway improvements and new roads. The resulting
system would provide good circulation within the Tri-Valley area. Figure 7-1 shows the
planned roadway system. Figure 5-2 in Chapter 5 shows the planned changes to
freeway interchanges. Details on planned intersection lane configurations are included
in the Technical Appendix. A detailed listing of the planned roadway improvements is
shown in Table 7-1.
Critical Regional Projects
Since most arterial improvements and extensions are local-serving and will be paid for
by new development, the financial plan needs to focus on the funding of the larger
projects with regional significance. The TVTC developed the following list of criteria to
define projects for inclusion in a potential regional impact fee program:
1. The project must involve a route of regional significance as defined by the TVTC
for the transportation plan (see Figure 1-1)..
2. Transit projects can be included.
3. The project must be identified in an adopted plan.
4. The project would not be built as a direct developer improvement.
While not a part of the originally adopted list, a fifth criterion discussed by the TVTC
is that the project should serve more than one jurisdiction.
DBy these criteria, the following planned projects would qualify as being regionally
significant. These have been preliminarily determined to be of highest priority for
funding due to their demonstrated need in meeting the TSOs through 2010. This list
may be modified in subsequent studies.
D 1. I-580/1-680 Interchange. Southbound-to-eastbound flyover.
2. Route 84. Four lanes on Vallecitos Road, six lanes on Isabel Avenue, including
interchange improvement at I-580/Vallecitos and a new interchange at
DI-580/Isabel.
3. I-680 Auxiliary Lanes. From Diablo Road to Bollinger Canyon Road.
4. BART Extension. From Castro Valley to East Dublin, including two stations in the
Tri-Valley.

' Recommended Improvement Plan
' 5. 1-580 HOV Lanes. From Tassajara Road to North Livermore Avenue.
6. I-680 HOV Lanes. From Route 84 to top of Sunol Grade.
7. ,Ramp Metering. Add ramp.metering with HOV bypass to all freeway interchanges
in the Tri-Valley.
8. I-680/Alcosta Interchange. Capacity improvements including replacement of
southbound off-ramp with hook ramp.
9. I-580/Foothill Interchange. Conversion to partial cloverleaf design.
' 10. Crow Canyon Road Safety Improvements. This project consists of realigning the
roadway, construction of shoulders and improving sight distance, all aimed at
' improving traffic flow and safety on Crow Canyon Road between Bollinger Canyon
Road and MM 4.45 (located one mile north of Norris Canyon Road).
11. Vasco Road Safety Improvements. This project consists of the realignment of Vasco
Road from the new Vasco Road to the Livermore City limit, without increasing the
capacity of the gateway. This is consistent with the standards used in the Vasco
Road relocation project by the Contra Costa Water District in conjunction with the
Los Vaqueros reservoir project.
The following three projects are also included in the transportation plan but are
preliminarily considered-by the TVTC to be of lower priority for the 2010 planning
horizon. These projects are considered important to the future of transportation in the
Tri-Valley but are not needed to meet the Transportation Service Objectives through
2010.
1. I-580 HOV Lanes. Completion of the HOV project on I-580 from Livermore Avenue
to the Alameda County border.
' 2. 1-680 HOV Lanes. Completion of the I-680 HOV Lane project from I-580 to
Route 84. This would create a system of continuous HOV lanes on I-680 through
the Tri-Valley.
3. I-580/1-680 Interchange. Construction of the northbound to westbound flyover
ramp. This improvement has been identified by Caltrans as the next step in
' improving the I-580/1-680 interchange. This second flyover ramp would eliminate
all existing weaving sections.
' The Transit Plan
' The Tri-Valley Transportation Plan includes several transit improvements. These were
developed by a transit subcommittee of the TVTAC. The subcommittee included
representatives from BART, CCCTA (County Connection), LAVTA (WHEELS), and
Contra Costa County. The plan includes the following major components: BART
extension to east Dublin (two stations), park-and-ride lots, express bus service in
heavily traveled corridors, local bus service to new development areas, reoriented local
bus service to serve BART and park-and-ride lots, and decreased headways on existing
' Barton-Aschman Associates, Inc. 141
Recommended Improvement Plan ,
routes. For modeling purposes, specific bus routes were developed and tested. Howev-
er,
owev er, the TVTP is not intended to be a detailed long-range plan for transit provision.
Therefore, the specific routes, which are described in the Appendix, should not be
interpreted literally, but as representative of the type of service (headways and ,
corridors served) that should be provided.
The following are descriptions of the planned transit service. ,
BART Extension: The plan includes the BART extension to East Dublin with two
stations in the Tri-Valley. The extension is currently under construction and is '
projected to open in 1996. The planned BART headways are nine minutes. Both
stations are assumed to have parking lots. The patronage forecasts from the traffic
model indicate demand for at least 6,000 parking spaces combined for the two stations. ,
Two BART feeder bus lines would be operated: one to Bishop Ranch and Danville, and
one to Livermore. Both would have 30-minute headways.
Park-n-Ride Lots: The plan includes 11 new park-n-ride lots (See Figure 7-2). These '
would be served by various bus lines and could also serve as staging locations for
carpools. '
County Connection: The plan calls for the expansion of service from the current three
lines serving Tri-Valley (30-minute headways) to eight lines. Three lines would have
30-minute headways and five lines would have 20-minute headways. The lines would '
serve Danville, San Ramon, Bishop Ranch, Dougherty Valley, and some would extend
down to the East Dublin BART station.
WHEELS: Under the plan, WHEELS service would expand from the current 11 lines
with 30-60 minute headways to 21 lines, all with 30-minute headways. The route
system would be extensively revised to serve the two BART stations, park-n-ride lots, ,
and the newly developed areas of East Dublin and North Livermore. Some routes
would also extend into San Ramon and Danville.
Express Bus Service: The plan calls for the provision of nine new express bus routes
operating in the I-680, I-580, and Vasco Road corridors. The following areas are
served: '
1. Santa Clara County to Pleasanton
2. Hayward to San Ramon '
3. Santa Clara County to San Ramon
4. Fremont to San Ramon
6. Brentwood to Pleasanton '

' Recommended Improvement Plan
These routes each have 20-minute headways. The plan does not specify what agency
would operate the express routes. To serve the Altamont Pass commute, it is anticipat-
ed that the San Joaquin Regional Transit District will offer express bus service to
' various locations in the Bay Area.
' Freight Transportation
Freight transportation provides an important contribution to the economy. As such, it
' is both necessary and appropriate that the Plan give strategic priority to the move-
ment of freight. To highlight the strategic importance of freight transportation, this
plan designates I-580 as a Critical Freight Route and I-680 as a Major Freight Route.
These designations are consistent with the Alameda County Long-Range Transporta-
tion Plan. Truck volume studies show that I-580 at the Altamont Pass carries more
than 20,000 trucks each weekday while I-680 at the Sunol Pass carries more than
' 15,000 trucks per day.
As a Critical Freight Route, I-580 should be accorded priority for intermodal funding
under ISTEA. Also, I-580 should be operated in a manner which ensures that freight
can be moved with maximum efficiency. To this end. expenditure priority should be
given to those operational improvements necessary to prevent the encroachment of
commute traffic from congesting Critical Freight Routes during midday hours (midday.
hours are defined from 9:00 AM to 3:00 PM). As a Major Freight Route, I-680 should
be given consideration for intermodal funding under ISTEA.
' One transportation management strategy to be evaluated further and considered later
is to implement ramp metering during midday hours, as necessary, to maintain
acceptable speeds on I-580 and I-680. At such time as environmental review is
conducted for a systemwide ramp metering plan for the Tri-Valley, ramp metering
during midday hours to maintain smooth freight movements should also be considered.

Financial Plan
Implementation of the Tri-Valley Transportation Plan will be financed through a
combination of public and private sources. The primaryexisting funding sources '
include the Measure C program in Contra Costa County and the Alameda County
Measure B program. Funds are also available through various federal, state and local
programs. These are administered through MTC via the Regional Transportation Plan.
All assumptions for state and federal funding are taken from MTC/RTP estimates.
Alameda Count '
Y
Measure B '
Alameda County voters approved Measure B, a 15-year one-half percent sales tax, in
November, 1986. Measure B was based on the August, 1986 Alameda County Trans-
portation Expenditure Plan. Approximately two-thirds of the total Measure B revenue
is to be spent on 10 capital improvement projects. Three of the 10 projects are located
in the Tri-Valley area. The total Measure B funding programmed to Tri-Valley is
$293.6 million.
• Interstate 5801680 Interchange. $89.3 million to provide a southbound-to-
'
eastbound direct connector.
• Route 84. $19.9 million to construct a two-lane road on the Isabel Avenue align- '
ment between Jack London and Concannon. Other sources (MTC, Livermore
impact fees, Ruby Hills development) will contribute $43.0 million to overall Route
84 improvements. '
• BART Extension. $170 million to extend BART from San Leandro to
Pleasanton/Dublin. Other sources will contribute $367 million to this project.
Barton-Aschman Associates, Inc. 146
' Financial Plan
Refer to the Alameda County Transportation Authority's Strategic Plan, Fiscal year
1993/94, for project and funding specifics. The remaining money is being distributed
directly to local entities for current transportation needs.
' Alameda County Plan
' The Alameda County Long-Range Transportation Plan identifies a two-phased, Tier 1
and Tier 2, investment program to maintain and enhance the county transportation
network. The Tier 1 program is based on reasonable expectations of available revenue
' sources over the next 20 years to 2014. The County is expecting to receive a total
of$1.15 billion during this period. These sources are in addition to the Measure B
funds. The Metropolitan Transportation Commission has gone through a similar
process for the whole Bay Area and identified what they call Track 1 projects. These
are projects that would be funded by the assumed continuation of existing state and
federal funding programs. Table 8-1 shows the Tier 1 projects in the Tri-Valley and
' compares the Alameda County list to MTC's Track I.

Contra Costa County
On November 8, 1988, the voters of Contra Costa County approved Measure C, which
became effective in April 1989. The Measure C "Expenditure Plan" directs funds
generated through Measure C to a wide variety of planning, operational and capital ,
improvements, collectively designed to improve transportation service in Contra Costa
County. The "Expenditure Plan" includes Capital Improvement projects that fall into
Barlon-Aschman Associates, Inc. 148
Financial Plan
' three categories: (1) Highways and Arterials, (2) Transit, and (3) Trails. In addition
there are five programs included within Measure C: (1) Elderly and Handicapped
Transit Service, (2) Local Street Maintenance and Improvements, (3) Carpools,
Vanpools and Park-and-Ride Lots, (4) Bus Transit Improvements and Coordination,
' and (5) Regional Transportation Planning and Growth Management. Approximately 70
percent of the revenues are allocated to capital improvement projects and 30 percent
to programs. The seven-year "Strategic Plan" provides detailed specific commitments
' for specific projects. The balance of the program is represented as lump sum amounts
shown by year. The current "Strategic Plan" is detailed through fiscal year 1997. It is
updated every two years and is currently undergoing its first update. Tri-Valley
projects identified by CCTA for Measure C funding to date include the following. The
total Measure C funding in Tri-Valley is $27.4 million.
' - I-680 Auxiliary Lanes: $10 million to construct auxiliary lanes between Diablo
Road and Bollinger Canyon Road interchanges. Other sources must contribute $27
million. (Source: Regional Transportation Plan, MTC.)
- Construct Fostoria Parkway Overcrossing: $11.5 million to construct the I-680
overcrossing. Other funding sources amount to $1.8 million. (Source: CCTA, 1993
' Congestion Management Program, Appendix E.)
Arterial Street Improvements: $5.9 million to modify/improve the arterial road
network in Tri-Valley. (Source: CCTA, 1993 Congestion Management Program,
' Appendix E.)
Private Funding
The majority of the arterial system and interchange improvements in the Tri-Valley
will be built or funded by new development. This is reflective of the fact that the
arterial extensions and widenings are to build additional capacity to serve new
development. The new roads and widenings will either be built directly by the
developers or will be paid for through local traffic impact fees. Livermore, Pleasanton,
Danville, and San Ramon all have development fees. These fees will in a large
measure fund the needed arterial infrastructure for the expected year 2010 transporta-
tion system. However, there are 11 critical regional projects that either lack funding
entirely or are not completely funded. The need for these projects cannot be tied to any
single development or even any single city. These are described below.
Critical Regional Projects
Since most arterial improvements and extensions are local-serving and will be paid for
by new development, the financial plan needs to focus on the funding of the larger
projects with regional significance. If the developer-funded, assumed local arterial
improvements are not built, changes to the financing plan would be necessary. The
TVTC developed the following list of criteria to define projects for inclusion in a
potential regional impact fee program:
Barton-Aschman Associates, Inc. 149
Financial Plan
1. The project must involve a route of regional significance as defined by the TVTC
for the transportation plan (see Figure 1-1).
2. Transit projects can be included.
3. The project must be identified in an adopted plan.
4. The project would not be built as a direct developer improvement.
While not a part of the originally adopted list, a fifth criterion discussed by the TVTC
is that the project should serve more than one jurisdiction.
By these criteria, the following planned projects would qualify as being regionally
significant. These have been preliminarily determined to be of highest priority for
funding due to their demonstrated need in meeting the transportation service-objec-
tives through 2010.
1. 1-58011-680 Interchange. Southbound-to-eastbound flyover.
2. Route 84. Four lanes on Vallecitos Road, six lanes on Isabel Avenue, including a
new interchange at I-580/Isabel.
3. 1-680 Auxiliary Lanes. From Diablo Road to Bollinger Canyon Road.
4. BART Extension. From Castro Valley to East Dublin, including two stations in the
Tri-Valley.
5. 1-580 HOV Lanes. From Tassajara Road to North Livermore Avenue.
6. 1-680 HOV Lanes. From Route 84 to top of Sunol Grade.
7. Ramp Metering. Add ramp metering with HOV bypass to all freeway interchanges
in the Tri-Valley.
8. I-6801AIcosta Interchange. Capacity improvements including replacement of
southbound off-ramp with hook ramp.
9. 1-580/Foothill Interchange. Conversion,to partial cloverleaf design.
10. Crow Canyon Road Safety Improvements. Realigning the roadway, construction of
shoulders and improving sight distance, all aimed at improving traffic flow and
safety on Crow Canyon Road between Bollinger Canyon Road and one mile north
of Norris Canyon Road.
11. Vasco Road Operational Improvements. Realignment and upgrading of Vasco Road
from the Alameda County line to the Livermore City limit,�while retaining the
two-lane cross-section.
Barton-Aschman Associates, Inc.
150
Financial Plan
12. Express Bus Service. Providing the capital cost of adding nine express bus routes
connecting the Tri-Valley with surrounding communities and taking advantage of
the freeway HOV lanes.
The following three projects are also included in the transportation plan but are
preliminarily considered by the TVTC to be of lower priority for the 2010 planning
horizon. These projects are considered important to the future of transportation in the
Tri-Valley but are not needed to meet the Transportation Service Objectives through
2010.
1. I-580 HOV Lanes. Completion of the HOV project on I-580 from Livermore Avenue
to the San Joaquin County border.
2. I-680 HOV Lanes. Completion of the I-680 HOV Lane project from Alcosta Boule-
vard to Route 84. This would create a system of continuous HOV lanes on I-680
through the Tri-Valley.
3. I-58011-680 Interchange. Construction of the northbound to westbound flyover
ramp. This improvement has been identified by Caltrans as the next step in
improving the I-580/I-680 interchange. This second flyover ramp would eliminate
all existing weaving sections.
Funding for Regional Projects
Most of the regional projects have some funding already committed (see Table 8-3).
Additional funds are needed to make up the shortfall. This plan does not rely on
Alameda County Tier 2 funding becoming available. The total shortfall is $311.1
million.
The regional improvements are all necessary to serve new development. Because
Tier 2 funding is uncertain and because the regional projects are vital to safe and
efficient transportation in the Tri-Valley, a subregional impact fee should be adopted
to cover the shortfall.

Subregional Impact Fees
There is general consensus at TVTC that unbuilt development should pay its fair
share to mitigate the impacts of traffic generated by that development. Construction of
the major regional improvement projects listed in Table 8-3 is estimated to cost close
to $1 billion, and constitutes the regional improvement program needed to serve
existing and planned development in the Tri-Valley and surrounding region. Roughly
70 percent of the total project cost is expected to be funded through local, state, and
federal sources over the next 20 years. The remaining 30 percent is unfunded. TVTC
wishes to explore the possibility of generating revenues for this unfunded portion
through implementation of a subregional transportation impact fee.
For illustrative purposes, a fee amount was estimated assuming that at the need for
new transportation facilities will be generated equally by residential and commercial
growth, and that funding responsibility would be equally divided among these two
types of development. Furthermore, the fee calculation uses a trip-based methodology,
which means that the amount of the fee would depend upon the number of peak-hour
trips generated by each new development project. Finally, it was assumed that the
total unfunded amount shown in Table 8-3 would be paid for through the subregional
transportation impact fee. This final assumption is subject to change, given that the
estimates for future public funding of$694 million is tenuous at best, and that the
nexus relationship between traffic impacts generated by new development, and project
needs, would need to be fully evaluated before a fee could be adopted. Also a number
of procedural and administrative hurdles would need to be cleared in order to adopt
such a fee.
The results of the trip-based fee calculation was translated into equivalent dwelling
units for residential development, and square footage for non-residential development.
The fee amount for new residential development would be approximately $2,800 per
dwelling unit. The amount for office, commercial, or industrial use would be approxi-
mately $6'per square foot.
This discussion is preliminary in nature. The project list, cost estimates, and possible
fees are subject to change pending further discussion at the TVTC and evaluation of
the nexus relationship between new development and its impact on traffic.
TVTC recognizes that imposition of$6 per square foot fee on non-residential develop-
ment could have a negative impact on the economic development of the Tri-Valley
area. Accordingly, TVTC will explore in greater detail the fee calculation methodology,
and approaches to reducing the fee burden on projects that could significantly support
continued economic growth in Tri-Valley. At a minimum, further study will be needed
to determine the following:
1. The extent to which traffic generated by commercial development uses the freeway
facilities identified in Table 8-3; and
Barton-Aschman Associates, Inc. 153
i
Financial Plan
2. The extent to which commercial-generated traffic contributes to peak-hour conges-
tion. For example, AM peak-hour traffic generated by retail development generally
occurs after the work-trip commute peak hour.
These fees are illustrative of the level of impact fees required but are not meant to be
final calculations. The TVTC must go beyond this plan to develop an impact fee
program that would establish a legal nexus between development levels and fees
charged and also clarify many ancillary issues. At a minimum, the program needs to
consider the following issues:
• Land Use Categories. Will there be one fee for all residential development or will
it vary with density? Similarly, how many commercial categories will be used?
Jurisdictions typically use three categories: retail,industrial, and office. Would
even more categories be useful? I
• Credits. Should certain projects that have already contributed regional improve-
ments, such as Hacienda Business Park, be entitled to a fee credit?
• Exemptions. Should certain project with significant social value, such as low-
income housing, be exempt from fees? What about projects that significantly
enhance the area's-economic development?
• Fee Collection. How and by whom should the fees be collected? Who will bank the
funds and contract for transportation projects? ;
• Transfer of Funds Between Jurisdictions. A subregional fee collected among the (�
seven jurisdictions of Tri-Valley could potentially result in a situation where funds =�
collected in one jurisdiction were expended on the construction of regional projects
in another jurisdiction. The concept of a subregional fee for the Tri-Valley will
need to address the acceptability and magnitude of cross jurisdictional transfers of
fee revenues. TVTC has established that it does not wish for any regional fee
revenues collected in Tri-Valley to be expended on projects outside of the Tri-
Valley subarea.
• Relationship to Future Countywide or Regionwide Fee Programs. If in the future, a.
countywide or regionwide (nine-county Bay Area) fee program is established, the
relationship of those programs to the Tri-Valley regional fee will need to be
addressed, especially with regard to crediting an in-place Tri-Valley fee toward a
countywide fee.
• Impact of the Fee on Growth. Fee levels that are too high for either residential or
nonresidential development may adversely affect the efforts of TVTC jurisdictions
to promote economic growth or affordable housing opportunities. To address the
concerns, the TVTC will seek the assistance of the Association of Bay Area
Governments to evaluate the economic impacts of a regional transportation impact
fee on economic and residential growth in the Tri Valley area.

Financial Plan
Protection of the Fee's Revenue-Generating Potential. During the development of
the Plan, major development proposals in the Tri Valley have been approved and
their ability to generate revenues for regional transportation projects has been
lost. Further erosion of the revenue-generating potential of the fee program may
continue as details on the fee program are resolved. TVTC encourages local
jurisdictions to condition any development approval with participation in a
regional transportation impact fee program, contingent on the eventual agreement
by Tri Valley jurisdictions on a fee program. Following adoption of this plan, '
TVTC will consider the fee study as it highest priority. TVTC will pursue comple-
tion of the fee study within 12 months.
Spatial Distribution of Fees and Benefits
Elected officials are concerned about where impact fees are collected and where they
are spent. Table 8-5 shows the 2010 estimated peak-hour usage pattern for each of the
high-priority projects. Each jurisdiction would benefit from two or more of the regional
projects.

Financial Plan
Table 8-6 compares payment to expenditures by jurisdiction. Expenditures are summa-
rized based on the physical location of improvements and based on the amount of new
development trips using the new facilities. Based on usage, Livermore is the primary
+� beneficiary of impact fees because of two factors: (1) Livermore has more planned
�i growth than any other jurisdiction; and (2) Livermore will be the primary user of
Route 84, which is the largest unfunded component of the plan. Whether considering
benefit by facility location or by usage pattern, the impact fees would result in a
transfer of$18 to 20 million from Contra Costa County jurisdictions to Alameda
County jurisdictions. However, this calculation includes only the unfunded portion of
each project. If Measure C and Measure B monies are added to the analysis, then the
amount spent in each county is almost exactly equal to the money generated.

Financial Plan
Potential Future Funding Sources
Other future.funding sources have been discussed for the Tri-Valley. Alameda County
has discussed a Tier 2 funding program, which includes a 10-cent-regional gas tax and
a continuation of Measure B. There is also the State and Local Transportation
Partnership Program (SLTPP), which could provide up to 50 percent reimbursement of
construction costs. The Mid-State Toll Road has also been proposed to provide trans-
portation capacity in the Route 84 corridor without public investment. The major
potential future sources are discussed briefly below, although because of their uncer-
tainty, the Tri-Valley Transportation Plan does not rely on their provision.
County Sales Tax Measures
The county sales tax measures, currently funding several transportation improve-
ments, have a limited life span. Measure B in Alameda County will expire in 2002.
Measure C in Contra Costa County will expire
e in 2008. There is a chance that these
sales tax programs, through a successful election, could be extended. They were
originally passed with a simple majority vote. Recent court decisions in other counties,
however, have shown that a two-thirds vote may be required to enact future tax
initiatives. Achieving a super majority at the polls is considered nearly impossible for
a proposed tax increase ballot measure.
County Gas Tax/Regional Gas Tax
A county tax or regional tax may be imposed on motor vehicle fuels for the purposes of
transportation investment according to enabling state legislation which was adopted in
1981. The tax would be imposed in increments of one cent per gallon per year with no
state-imposed lifetime limit. Prior to imposition and collection of a tax, a proposition
granting authority to the county to impose the tax must be submitted and approved by
the voters at an election. A proposition may be submitted to the voters only if a
written agreement is made with respect to allocation of the revenues between the
county and the cities.
Additional gas taxes would provide several benefits. Drivers will look for alternatives
to the private automobile as driving costs (e.g., increased fuel prices)increase,
reducing systemwide demands. Demand may be reduced by telecommuting, ride-
sharing, transit, or linking trip purposes. The additional revenue obtained as a result
of the higher tax would create a larger"pot of money" for transportation related
projects.
Toll Financing
A toll road, the Mid-State Toll Road, has been proposed for the Route 84 corridor,
connecting between 1-680 in Sunol and the Antioch area. The toll road is now in the
planning stages, with an environmental impact report(EIR) under development. At
the request of MTC and Tri-Valley agencies, the EIR will study several options in the
Barton-Aschman Associates, Inc. 158
Financial Plan
corridor, including transit. The City of Livermore and the Alameda County CMA have
adopted resolutions opposing a private toll road in the Route 84 corridor. A public toll
road has also been discussed, although no official positions have been taken. Because
of the uncertain nature of the Mid-State Toll Road, either public or private, it is not
included as a funding source for the Tri-Valley Transportation Plan. Nevertheless, it
must be recognized that $137 million of the unfunded portion of the plan is attribut-
able to Route 84. If the decision were made to adopt and build a toll road within the
2010 horizon of this plan, the proposed regional impact fee could be reduced, or the
$137 million could be applied to one of the second priority regional projects discussed
in the next section. This assumes that none of the $137 million would be needed to
provide the required free roadway in the,toll road corridor.
Potential Future Transportation Projects
The plan identifies three regional transportation projects that would be desirable for
the area but are not required to meet transportation service objectives: high-occupancy
vehicle lanes on 1-680 between Alcosta and-Route 84, high-occupancy vehicle lanes on
1-580 between North Livermore Avenue and the San Joaquin County line, and the
addition of a northbound to westbound flyover ramp at the 1-580/1-680 interchange. If
more transportation funds become available than were assumed in this plan, the
TVTC would like them to be allocated to these projects.
Table 8-7 provides preliminary cost estimates for these projects. In current dollars the
total cost would be $245 million.

Financial Plan
Detailed Finance Plan
Table 8-8 provides the detailed financing plan for the 2010 planned network. Note that
the cost estimates are preliminary and ultimately need to be refined by the responsible
jurisdiction. The overall program cost is projected to be $1,482,310,000. Approximately
47 percent of the projected cost ($695,690,000) is publicly funded, primarily through
Measure B and Measure C programs. Thirty-three percent ($491,720,000) of the
projected cost would be funded by direct developer exactions from localities. These
would be either local impact fees or required project mitigation improvements. The
remaining 20 percent ($294,900,000) of the program cost would be funded by the
subregional transportation impact fee.
Besides the subregional impact fee, the other aspect of the finance plan that needs to
be finalized is the cost sharing arrangement between jurisdictions that have responsi-
bility for a particular route of regional significance. One option is to adopt a policy that
each jurisdiction is responsible for the routes within its boundaries. Another option is
to determine where traffic goes from each jurisdiction and assess funding responsibili-
ty based on proportional traffic shares. In any event, the cost sharing formulae need to
be developed through negotiation between affected jurisdictions.

Action Plan
The Action Plan lists each route of regional significance along with the 2010 planned
improvements and resulting traffic volume and levels of service. The Transportation Plan
recommendations are distilled into distinct action statements for each route of regional
significance. Potential actions are also listed. These were considered by the TVTC and
serve as background to the recommended actions. The Action Plan also includes a list of
responsible agencies to implement the actions for each route of regional significance.
Actions of Regional Significance
Listed below are regional actions which are intended to reduce congestion and improve
efficiency on the regional transportation system. These actions are broader in nature than
the route-specific actions identified in the following subsection. Implementation of regional
actions requires a coordinated effort among local jurisdictions and regional agencies. The
TVTC jurisdictions, while not able to directly implement all of these actions, agree to use
every opportunity to work cooperatively with responsible agencies, including Caltrans,
BART, and MTC, toward their successful implementation.
1
1. Conduct a subregional traffic impact fee study to address the funding issues described
in Chapter 8, "Financial Plan," and to address the list of priority transportation
projects described in Chapter 7, "Recommended Improvement Plan."
2. Implement a subregional traffic impact fee to pay for planned, but unfunded, trans-
portation improvements.
3. Increase AVR for work (commute) trips from 1.1 to 1.2. Achieve this increase by
requiring and enforcing employer-based TDM programs. Pleasanton's TSM ordinance
is an example of how to implement a program.
1 Barton-Aschman Associates, Inc. 165
Action Plan
4. Install ramp metering at all freeway on-ramps, provided study shows metering would
be equitable and effective as agreed to by Caltrans and the TVTC and provided
sufficient stacking space is available. Provide HOV bypass lanes wherever space
permits. The TVTC should take the lead and seek funding for a study of ramp
metering.
5. Support growth that achieves an overall jobs-housing balance within the Tri-Valley.
6. Support regional gasoline taxes to encourage commute alternatives and provide funds
for needed transportation projects.
7. Support development of a seamless HOV network in the Tri-Valley to encourage the
use of carpools and bus transit. TVTC shall work cooperatively with Caltrans, MTC,
and affected jurisdictions to explore opportunities for expanding the HOV system,
especially on 1-580, subject to cost-effectiveness analysis and/or change to legislation
prohibiting them.
8. Request that transit agencies conduct a study of the formation of a transit benefit
district to finance ongoing transit operating costs.
9. Support the preparation by Caltrans of an incident management plan for the
state highways in the Tri-Valley area. The TVTC recognizes that incidents can
have a profound effect on traffic conditions both on the freeways and on the
arterials.
Action Plans for Routes of Regional Significance
This section details the various objectives and actions for each designated route of
regional significance within the Tri-Valley. Specific Traffic Service Objectives are present-
ed, together with a set of actions directed at achieving those objectives. The parties
responsible for implementing the actions are also identified. Once the Plan is adopted,
each jurisdiction will be responsible for making a good-faith effort to implement the
agreed-upon actions. In Contra Costa County, a jurisdiction's compliance with the 1998
Measure C Growth Management Program will be judged based upon its efforts to
implement agreed-upon actions.
The actions, programs, and measures identified in the Action Plan are intended to
mitigate congestion and achieve the Traffic Service Objectives assuming that future traffic
will be constrained by the limited capacities of highway facilities serving the Tri-Valley
Gateways (see Chapter 5, "Gateway Constraints"). An individual jurisdiction may also
elect to implement more stringent actions, measures, or programs, in addition to those
identified below, on facilities within its jurisdiction. For example, a jurisdiction's individu-
al mitigation program could respond to higher future traffic levels, assuming no gateway
constraints (see Figure 5-4).

The Board of Supervisors of Contra Costa County RESOLVES THAT:
WHEREAS, the Measure C-1988 Growth Management Program (Measure C-1988) compliance
requirements for Regional Routes requires each jurisdiction to implement specified local actions designed to
attain Traffic Service Objectives (TSO 's) in a timely manner, consistent with adopted Action Plans;
WHEREAS, the Draft Tri Valley Transportation Plan/Action Plan, 2nd Draft (Draft Action Plan),
proposes local actions that include growth controls and prohibits certain transportation improvements that,
coupled with the Level of Service TSO's, would preempt local land use decisions on proposals that are
currently under review by the Board of Supervisors;
WHEREAS Measure C•1988 compliance requirements cannot preempt local )and use decisions or
require local jurisdictions to accept unwanted construction projects;
WHEREAS the Draft Action Plan includes a TSO for Bollinger Canyon Road that is not consistent with
the minimum Level of Service standard required for development in the Dougherty Valley;
WHEREAS the Draft Action Plan includes statements interpreting the Dougherty Valley Settlement
Agreement that are inconsistent with the interpretation of the Board of Supervisors;
WHEREAS the Draft Action Plan does not substantiate at this time that the actions it recommends
or potential actions, will reasonably ensure compliance with the TSO's in 2010;
WHEREAS the Draft Action Pian does not provide an adequate nexus between the recommended
regional fees to be paid by new development in Contra Costa with the benefit these fees provide such
development;
WHEREAS various other actions in the Draft Action Plan do not reflect the Board's concerns in .
managing regional traffic impacts from future growth in the Tri Valley area;
WHEREAS all affected jurisdictions must agree to the actions before the Action Plans are finalized
and adopted; and
WHEREAS this resolution does not conflict with the condition included in the Contra Costa
Transportation Authority's July 20, 1994 approval on the County's Measure C•1988 Annual Compliance
Checklist regarding the application of certain traffic level of service standards for intersection in Danville and
Sen Ramon.
NOW,THEREFORE,BE IT RESOLVED by the Board of Supervisors of Contra Costa County to support
the following modifications to the Draft Action Plan:
Recommended actions for growth limits outside the Dougherty Valley Specific Plan area shall be
deleted from the Action Plan;
Recommended prohibitions to road improvements in Danville shall be deleted from the Action Plan

in Danville or preempt Iacal land use decisions on proposals that are currently under review by the
Board of Supervisors. This process for meeting TSO's should be defined as follows:
1n order to meet the TSO requirements, the level of development that may be
approved by a local jurisdiction shall be consistent with the identified
transportation improvements and programs for which funding is,reasonably
assured. Other jurisdictions may elect not to implement such improvements

development.
The Action Plan shall revise the recommended action No.2 for Vasco Road as shown in the following
italicized text:
Oppose increases to mixed-flow capacity or Vasco Road in Alameda County.

Jurisdictions in Tri-Valley may implement a proactive Growth and Congestion Manage-
ment strategy once a detailed growth management study has been conducted. The study
should indicate the development reductions, land use density reductions, or other types of
growth management/control that would be required for each applicable Tri-Valley
jurisdiction in order to achieve TSO standards. Any development reduction should be
proportional to the traffic distribution percentages for each jurisdiction. Also, the impact
of this development reduction to traffic impact fees should be analyzed. All jurisdictions
will then review this information and know exactly how much reduction in development a
or growth management/control is needed to meet the TSOs.

As specified in the Joint Powers Agreement (JPA) that created the TVTC, adoption of
the Tri-Valley Transportation Plan shall require the unanimous vote of all members of
' the TVTC. Following plan adoption, all TVTC member jurisdictions agree to consider
the Plan when adopting or amending circulation elements of their general plans and
specific plans, zoning ordinances, or capital improvement programs.'
While compliance with the Tri-Valley Transportation Plan (TVTP) is essentially volun-
tary among the Alameda County jurisdictions, at least until aspects of the TVTP
become part of the Alameda County Congestion Management Program, the Contra
' Costa County jurisdictions have a mandate for compliance. The TVTP constitutes the
Action Plan for the Contra Costa Tri-Valley jurisdictions, as required by Measure C.
Thus, to maintain compliance with Measure C, the Contra Costa County Tri-Valley
jurisdictions must make a good-faith effort to implement the planned actions, or risk
losing their return-to-source funds. Compliance is tied to local implementation of
action policies as set forth in Chapter 9, "Action Plan." One locality cannot be judged
' ineligible for local street maintenance and improvement funds because of the unwill-
ingness of another locality to participate in the process.

Plan Implementation, Monitoring, and Review
The TVTC has not addressed the issue of whether an environmental impact report will
be required for plan adoption. If an EIR is necessary, it should be jointly prepared by '
all jurisdictions, rather than prepared individually.
Plan Financing
Two elements of the financing plan for the TVTP require further study and action by
the Tri-Valley Transportation Council and its member jurisdictions: the subregional
transportation impact fee, and the cost-sharing formulae for road improvements that
benefit multiple jurisdictions.
Subregional Transportation Impact Fee. The TVTP lists the full range of projects that
could be included in an impact fee program. First, the list needs to be finalized and
adopted. Next, the details of the impact fee program need to be worked out. The
following issues should be considered. ,
1. How many development categories and what fee for each?
2. How would the fee affect growth? ,
3. Are there any exempted areas or land use types?
4. When will the fees be collected?
5. When will they be spent?
6. Who will act as banker?
7. What is the priority for constructing impact fee projects?
8. Are interim fee measures needed while the above issues are resolved?
After these issues have been resolved and the program specified, each jurisdiction
needs to adopt the program.
Shared Facilities. Implementation of much of the planned arterial system will be the '
direct responsibility of new development. Marty of the arterials, however, are shared
among jurisdictions. Table 8-8 shows the jurisdictions sharing responsibility for each '
of the planned improvements that will be paid for directly by developers.
For each of these improvements, a negotiated agreement needs to be reached about
cost sharing between jurisdictions. The cost-sharing approach could be based on which
jurisdiction's traffic is expected to use the facility, or it could be based simply on the
boundaries within which the facility lies, or a combination. These agreements should '
be negotiated in advance so that when development takes place, the responsibility for
road improvements is clear.

Plan Implementation, Monitoring, and Review
' Monitoring Transportation Service Objectives
The Transportation Service Objectives (TSOs) are the heart of the TVTP. While
1 certain growth assumptions are a.part of the plan, they serve merely to guide the
specification of a planned transportation system and financing program. The TVTP
does not control growth directly but indirectly through the TSOs.
' Under existing conditions, the TSOs relating to freeway and intersection levels of
service are largely being met. Future growth should be matched with road improve-
ments so that the TSOs continue to be met. Achievement of the TSOs depends upon
successful implementation of the actions, measures, and programs set forth in
Chapter 9, "Action Plan."
' In Contra Costa County, if, following good faith implementation of the Action Plan, a
TSO is not met, then the Plan would need to be reevaluated through the forum of
' TVTC and SWAT. Amendments to the Plan could include a relaxation of TSOs, a
strengthening of actions, or a combination of these approaches. In Alameda County,
the jurisdiction with the TSO violation can elect to modify growth rates, improve the
' facility, or seek a lower TSO standard through the amendment process set forth in
this chapter.
The TSOs related to mode split and average vehicle ridership are goals for achieve-
ment by 2010. They need to be monitored and adjustments to the plan made if
progress is not being made. Progress should be defined as increasing transit ridership
and increasing average vehicle ridership.
' The TSOs should be monitored every two years. The following describes how each
should be measured. Each jurisdiction should report the results of their monitoring
activities to the TV TAC for review. Any TSO violations should be forwarded to the
TVTC with recommended actions.
' Freeway Levels of Service. The TSOs are expressed both in terms of volume-to-capacity
ratio (V/C) and hours of congestion. Volume-to-capacity ratio and hours of congestion
can be measured with traffic counts or speed runs and should apply to mixed-flow
lanes only. The plan uses a capacity of 2,200 vehicles per lane per hour (1,100 vehicles
capacity for auxiliary lanes). Traffic counts can also be used to show duration of
congestion. Freeway monitoring should be done by Caltrans or the CMA.
Intersection Levels of Service. Intersection levels of service should be calculated using
the VCCC program for AM and PM peak hours based on turning-movement counts.
' Intersection monitoring should be conducted by the jurisdiction in which the intersec-
tion lies. The intent of the TVTP is to maintain the intersection TSO at all signalized
intersections. However, to avoid extensive data collection, each jurisdiction should
establish a list of critical intersections for monitoring.
Barton-Aschman Associates, Inc. 235
Plan Implementation, Monitoring, and Review
Mode Split. Mode split is virtually impossible to measure in the field, except through '
extensive home interview and work place surveys. These data are available every
decade from the U.S. Census and periodically from MTC. In between times, transit
ridership should be monitored as a surrogate for mode split. The mode split goal of the
TVTP can only be met if transit ridership increases annually. The transit operators
routinely collect and report annual ridership.
Average Vehicle Ridership. This TSO relates directly to commute trips. The Bay Area
Air Quality Management District has defined average vehicle ridership (AVR) and how
it can be calculated. To calculate AVR, annual employee surveys, conducted by '
employers, will be necessary. In many places these are already being done, and due to
air quality regulations, AVR will soon be annually reported by all employers with over
100 employees. All Tri-Valley jurisdictions have trip reduction ordinances, so AVR '
should be increasing in the future. Employers can take credit for shifting trips out of
the peak hour, shorter work weeks, and telecommuting in addition to promoting
ridesharing and transit usage. AVR should be monitored by each jurisdiction through
its trip reduction ordinance, or by the Bay Area Air Quality Management District.
Development Applications �.
Adoption of the Tri-Valley Transportation Plan will bring additions to the analysis
required of new development and does hot relieve the jurisdiction of meeting CEQA ,
and CMA requirements. This will affect both environmental impact reports and
general plan amendments. Transportation studies for development applications in the
Tri-Valley area shall assume gateway constraints described in.this plan. The Contra
Costa Transportation Authority should acknowledge the use of gateway constraints in
their Technical Procedures Manual.
Environmental Impact Reports. These should be circulated to all jurisdictions that
make up the TVTC, since most projects large enough to require an EIR will impact
more than one jurisdiction. In addition to any other cumulative analysis, the cumula-
tive analysis section of each EIR should consider the Expected Land Use and trans-
portation scenario on which the TVTP is based. The CMAs are required to use ABAG
projections. The Expected Land Use scenario is greater than ABAG so it is more
conservative and should be considered consistent. Transportation impacts should be
stated in terms of whether or not the project would lead to a violation of Transpor-
tation Service Objectives. Transportation mitigation measures should be consistent ,
with the TVTP network.
General Plan Amendments. The 2010 expected land use and transportation network, '
which are incorporated into the TVTP, are based on information supplied by the TVTC
member jurisdictions on their expected 2010 developments as of June 1994. Any
general plan amendments may affect either the adequacy of the planned network or
the financing plan. Any jurisdiction considering a general plan amendment should
evaluate its impact on the TVTP and demonstrate that the Transportation Service
Barton-Aschman Associates, Inc. 236
Plan Implementation,.Monitoring, and Review
' Objectives could still be met. If further transportation improvements are necessary
beyond what are in the TVTP, the jurisdiction should specify how they will be funded.
The Action Plans for Routes of Regional Significance will be based upon adopted
General Plan land uses, the existing road network, and planned improvements to the
network. Consistency with the Action Plans must be established for any changes to the
General Plan that may significantly reduce the ability of the facility to meet the
Traffic Service Objectives. The Regional Committee will be responsible for establishing
the type and size of amendment that will require review by the Regional Committee
and the process for implementing this review. Approval of a General Plan Amendment
found to be inconsistent with the adopted Action Plans may render the jurisdiction
ineligible for Local Street Maintenance Improvement Funds from the CCTA.
' Consistency with the Action Plans can be achieved by revising the proposed amend-
went, adopting local actions to offset impacts to the Route of Regional Significance, or
Council or Board denial of the amendment.
Growth Management Tools. The TVTP is not intended to be a land use control
document. While the plan is based on a set of growth assumptions, the plan should not
be interpreted as limiting growth to the assumed levels. Nevertheless, the plan does
establish Transportation Service Objectives, which may indirectly influence growth
rates. Growth beyond what is assumed herein may occur provided the TSOs are met.
If there are TSO violations, or projected TSO violations, in a Tri-Valley jurisdiction,
then that jurisdiction can either (a) implement transportation improvements (e.g., road
' widening) to correct the TSO deficiency on that affected network segment, or (b)
implement other measures intended to result in measurable improvements to TSOs on
the Routes of Regional Significance network and contribute to significant
' improvements in air quality. Failing this, the jurisdiction can refer the problem to the
TVTC for joint resolution. In the event that the TVTC cannot resolve the violation to
the mutual satisfaction of all members, the jurisdiction may modify the TSO standard,
but only if other jurisdictions are not physically impacted.
The tools and procedures for conducting General Plan updates in Contra Costa County
' and analyzing proposed General Plan amendments will be the same as those used in
preparing the Growth Management Elements. If the specific project or policy changes
are large enough to meet requirements established by the region in its adopted Action
Plan, the jurisdiction considering the Plan amendment must submit the amendment to
the Regional Committee for evaluation of its impact on the ability to achieve Action
Plan objectives. The Growth Management Program directs the RTPCs to evaluate
proposed amendments only in relation to issues affecting Action Plan success and
consistency. It will be the responsibility of the jurisdiction considering the amendment
to either:
r1. Demonstrate that the amendment will not violate Action Plan policies or the
ability to meet Action Plan Traffic Service Objectives; or
Barton-Aschman Associates, Inc. 237
Plan Implementation, Monitoring, and Review
2. Propose modification to the Action Plan that will prevent the General Plan amend- '
ment from adversely affecting the regional transportation network. .
If neither of these can be done, approval of the General Plan amendment may lead to '
a finding of non-compliance with the Growth Management Program.
Amending the Plan
Amendments can be triggered by: periodic review of the plan (every two to four years);
identification of TSO violations; a jurisdiction's proposal to adopt a major general plan
amendment that was not considered in the existing plan; and/or a change in the major
assumptions underlying the Plan. A change in the assumptions for Gateway Con-
straints would constitute the latter. ,
This plan is based upon the assumption that major gateways into Tri-Valley will not '
be expanded beyond the capacities assumed in the Expected Network as set forth in
Chapter 5. Any change in these assumptions, such as the addition of HOV lanes on
I-580 over the Altamont Pass, would require that this plan be amended to incorporate
revised assumptions for the Tri-Valley gateway constraints. Increased capacity at the
gateways could significantly increase projected congestion on downstream freeway
sections and arterial streets.
As specified in the Joint Powers Agreement governing the TVTC, amendments to the
p �' g g
plan will require a unanimous vote of all members of the TVTC.
Conflict Resolution
Because of the imP ortance of support for the Plan by all members of the TVTC, the ,
Council should act on a consensus basis. However, some cases may arise in which
consensus cannot be reached. In cases where conflict exists between jurisdictions '
within one county, resolution should be negotiated through the forum of the Conges-
tion Management Agency for the respective county. In cases where conflict exists
between jurisdictions in different counties, resolution should be negotiated through the ,
TVTC with the provisions of the Joint Powers Agreement applying. These provisions
state the following:
1. Unanimous vote of all members required for plan adoption and amendment.
2. Unanimous vote of all members required for adoption of annual work program and
budget.
3. Five votes required for grant applications, expenditure of funds, execution of
contracts, adoption of rules of procedure.

' Plan Implementation, Monitoring, and Review
' 4. Majority vote of all members present required for action on any other matter.
Future Role of TVTC
It is anticipated that implementation of the Action Plan will rest primarily with the
1 individual jurisdictions. However, the plan has identified some continuing functions for
the TVTC, as follows:
' Housing and future updates of the Tri-Valley Model
• Updates and amendments to the Tri-Valley Transportation Plan
• Development and implementation of a regional traffic impact fee
' Coordinated implementation of Actions requiring intedurisdictional cooperation

7 LEVEL OF SERVICE METHODOLOGY FOR
INTERSECTIONS
Level of Service is the primary measure of effectiveness to be used in
evaluating traffic operations at intersections on Basic Routes. All participating jurisdictions
must use the adopted Level of Service methodology in developing their General Plan Growth
Management Element, monitoring of Level of Service at Reporting Intersections, and preparing
Traffic Impact. Studies. If a jurisdiction elects to use another method for calculating Level of
Service, it must be used in addition to the adopted methodology described in this section.
iAction Plans for Routes of Regional Significance may also include Level of
Service as a quantifiable measure of effectiveness for Regional Routes. In these cases, the
adopted Level of Service methodology shall also be used.
The Level of Service methodology will be used to evaluate actual signalized
intersection levels of service given traffic count data. It will also be used to evaluate future
levels of service given traffic projections. The adopted method is similar to the Circular 212
Planning Method except that through movement capacity has been increased from 1,500
vehicles per hour to 1,800 vehicles per hour. Level of Service is calculated by critical
movement with lower capacities assumed for turning movements.
7.1 SATURATION FLOW RATES
The saturation flow rate is the basis for determining capacity the ca acit of an
intersection. It represents the maximum number of vehicles that can pass through an
intersection under prevailing traffic conditions. The CCTA has modified the Circular 212
Operations and Design Method by assuming a saturation flow rate of 1,800 vehicles per hour,
(rather than 1,500 vehicles per hour).
Saturation flow rates were measured at four intersections in Contra Costa
County in February, 1990 to verify the appropriateness of this saturation flow rate. The
method for collecting saturation flow rate data described in the 1985 Highway Capacity Manual
was used. The results are summarized in Table 8. Considerable variation in saturation flow
rates were observed at each intersection. The data suggested that the operations and design
capacities based on the 1,800 vehicles per hour saturation flow rate are frequently achieved
within Contra Costa County.

Technical Procedures
As indicated in Table 8 the saturation flow o rates varied by movement type.
Exclusive left-turn saturation flow rates were approximately 10 percent less than those for
through lanes. Saturation flow rates for shared left and through lanes were 18 percent lower
than for through lanes. Sufficient data was not collected to provide statistical accuracy for
these averages. They were consistent, however, with the passenger car equivalent (PCE)
values adjustments provided in Circular 212.
7.2 OPTIONAL CAPACITY REDUCTION
The effect of vehicle mix, intersection geometrics and other factors on
intersection capacity is well documented. These factors, however, are not considered directly
in the Circular 212 Planning Methodology. This was why a lower capacity (1,500 vph) was
originally selected for use in Circular 212.
The CCTA methodology, uses which s s a higher capacity (1,800 vph), may
underestimate existing or future congestion at some locations. The reductions in the capacities
�. provided in Table 9 are therefore optional, provided that measurement of saturation flow rates
justify the lower capacities. Once an intersection's capacity is reduced, it cannot be increased
unless intersection geometrics are improved and higher saturation flow rates have been
measured in the field. Under no circumstances can a signalized intersection capacity above
1,800 vph be used under the CCTA methodology. Saturation flow rates must be measured
using the technique described in Chapter 9, Appendix IV of the 1985 Highway Capacity
Manual. (A copy is provided in Appendix A of these Technical Procedures).
The saturation flow rates must be adjusted to establish the capacity for the
traffic movement considered. Adjustment of the saturation flow rates should be performed as
described in equation 9-1 of the 1985 HCM:

g = effective green time in seconds; and
C = intersection cycle length in seconds.

Technical Procedures
7.3 SUPPLEMENTAL ANALYSIS OF DELAY
Because the CCTA Level of Service method applies fixed critical lane volumes
uniformly throughout the county, the method may underestimate congestion at locations with
poor geometrics (older intersections with poor turning radii and small approach widths), or
overestimate congestion at locations with excellent geometrics (newer intersections with ideal
conditions) and aggressive drivers. The selected method may not identify locations where
severe congestion is limited to a single intersection approach, nor does it reflect significant
peaking and congestion within the peak hour.
To address these shortcomings, the following supplemental analyses may be
performed in addition to using the CCTA's method to identify congested locations:
Field measurement of delay on the congested approach or full
intersection can be collected using the methodology described in
Chapter 9, Appendix III of the 1985 Highway Capacity Manual
(HCM). The measured delay should be compared with those
provided in Table 9-1 of the HCM.
The summary of intersection levels of service should be supplemented to reflect .
the results of the delay analyses when significant variations are found.
T
7.4 LEVEL OF SERVICE CALCULATION METHOD
Signalized intersection levels of service should be calculated using the following
nine steps: -
STEP 1: Lane Geometry ,
Identify the number and type of lanes for each approach.
STEP 2: Intersection Volumes
Identify by counting (if analysis of existing conditions) or estimating (if analysis
of future conditions) left-turn, through, and right-turn volumes for each approach for the peak '
(design) hour volumes in vehicles per hour for each peak hour to be analyzed. In most cases,
the analysis will assess both the AM and PM weekday peak hour. For projects with peak
periods that occur during midday or on weekends, additional time periods should be analyzed.
cOeeEp10.10
Technical Procedures
STEP 3: Phasing
iIdentify the type of phasing (protected lefts turns, shared, or split) to be used at
the intersection.
STEP 4: Left-Turn Check
' The left turn check will apply to Level of Service calculations for future
conditions where the demand is estimated. Determination of the need for left turn phasing for
' existing conditions should be made based on actual traffic count, left turn delay, observed
queuing and accident history data. If permissive left turn phasing is provided, a check must be
made to determine if sufficient left turn capacity if provided. The left turn capacity is the
combination of left turn made against opposing through movements and left made during the
yellow change interval.
The capacity during the yellow change interval (Vc) — the maximum numbers
of left turns that can clean in this period — equals two times the number of signal cycles per
hour. If the number of cycles per hour is not known, assume that the maximum number of left
turns that can clear the intersection in one hour equals 90.
The capacity for left turns during the green cycle (VL) — the maximum number
of left turns that can clear against opposing traffic volumes — is estimated using*the following
equation:
VL = 1,200 l C J - Vo
J
Where:
VL = left-turn volume, in vehicles per hour, that can clear during the green for
opposing through traffic.
G = maximum green plus yellow time.*
C = cycle time for opposing through traffic.*
Vo = sum of opposing through and right-turn volumes, in vehicles per hour.
47
Technical Procedures
* If.either the maximum green time or the cycle time is
not known, use the through and right-turn volumes for
the approach divided by the number of lanes.
Add the number of left-turns calculated in the change interval Vc to the number
calculated in the permitted left for a total number of left-turns which can clear without a
protected left VL. If the number of left-turns calculated above (Left turn capacity) is more than
those estimated for the project, no protected left-turn phase is needed. If the number of left
iturns calculated above is less than the left turn demand, operating difficulties and increasing
delays will be experienced.
STEP 5: Adjust Turning Volumes
Two situations may require adjustment of observed turning volumes:
1. Right turns where no separate right turn lane is provided and significant
pedestrian activity exists,
2. Left turns where no separate left turn lane is provided.
The PCE adjustments recommended in Circular 212 (see Appendix A of the
Technical Procedures) should be used. If the VCCC model is-used, adjustments tc the turn
volumes should be made prior to entering into the program.
STEP 6. Calculate Volume-to-Capacity Ratio by Movement
The volume-to-capacity ratio of each of the 12 individual movements and any ,
combined movements of the intersection are calculated as follows:
r ► Right turn volumes from exclusive right turn lanes are adjusted for right turns
on red by the non-conflicting left turn volumes with a minimum reduction of 90
vehicles per hour. (Non-conflicting left turns go concurrently with the right
turn. For example, the non-conflicting left turn for the northbound right turn is
the westbound left turn.)
0. . Determine the capacity of each movement and each combined movement from ,
Table 9.

r
Technical Procedures
► Calculate the.volume-to-capacity ratio for each movement and combined
1 movement by dividing the adjusted volumes by the capacities. For combined
movements, use the combined volumes divided by the combined capacities.

2 Can include one shared lane (e.g. one exclusive left, plus one shared through left is
considered dual turn lane).
Assumes 45%-55% lane split.
` Assumes lane use 15% higher in the most used lane.
STEP 7: Determine Critical Volume-to-Capacity Ratios
Determine the highest total conflicting volume-to-capacity ratios for both the
north-south and east-west directions. For a non-split phased direction, the highest total of the
right-turn or the through (or through plus right-turn if no exclusive right-turn lane exists) plus
the opposing left-turn volume-to-capacity ratios are chosen. For a split phased direction, the
highest volume-to-capacity ratio from each of the approachs is chosen. Free right turns are
not included in the calculation since they are not under signal control.
Circular 212 does not clearly indicate how the critical movements are to be
selected for single lane approaches (that is, when all right, left and thru movements are made
from single approach lane). Under the Circular either the approach with the highest volume or
both approaches could be designated as the critical movement. As part of the Level of Service
method adopted by the CCTA, however, both approaches should be considered critical
movements.
