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-l. 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 Issues 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: Final Tri -Valley Transportation Plan Adopted July 1995 vi Barton-Aschman Associates, Inc.

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. 1-680 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 fore.casts 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 transportation 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. 1-680 and 1-580 within the Tri-Valley will operate at LOS E or better, provided ramp metering and HOV lanes are installed. Jobs and ho.using growth for year 2010 is projected. to be 99 percent anQ84peJ.'Cent, resp~ctively. Jobs and housingwo'llld 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. . . . Final Tri -Valley Transportation Plan Adopted July 1995 Ix Executive Summary · The transit mode share will increase slightly frpIIl exi$ting condi.tions. . Average vehicle occupancy will not change appreciably from existing conditions. \ I , 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. j 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 mayor 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 1-580 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 expectation,s. 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.

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 maintai~ing Transportation Service Objectives through their general plans. The transportation ~ervice obj~ctivesadopted by the. TV'rC areras {~llows,:. · Maintain Level of Service D (V/C < 0.90 or 0.91) 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. 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 measur- able improvements to TSOs on the Routes of Regional Significance network and contrib- ute 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. 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: · 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 Final Tri -Valley Transportation Plan Adopted July 1995 xiii Executive Summary 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 n~w, unapproved development. The Plan identifies 11 regional transportation improvements that could be funded through the impact fee (see Table E-l). Funding these 11 projects, the fee would calculate to about $2,800 per dwelling unit and $6 per square foot for commerciaVoffice/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.

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 Countyjurisdictions, 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 regul~tions 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 Final Tri -Valley Transportation Plan Adopted July 1995 1 , , I 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 (TV'!'C). 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 Signific~nce 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 approv~ls. These might relate to payment of mitigation fees, impl~mentation of TSMfI'DM measures, or phasing of development relative to infrastructure improvements.

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 I-68D, 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 1-680, 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 intercountyand/~r 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. Tbe 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. Final Tri -Valley Transportation Plan Adopted July 1995 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-5801I-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. · 1-680 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 (1-580) 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.

Figure 2-1 shows interchange locations. High occupancy vehicle (HOV) lanes are under construction between SR 24 in Walnut Creek and the county line at Alcosta Boulevard. 1-680 from 1-580 to Santa Clara County was widened a few years ago and includes sufficient right-of- way for additional lanes. I-680 is a designated major freight route by the Alameda County CMA, and there are truck climbing lanes over the Sunol grade. State Route 84 (SR 84) is an arterial.street including First Street and Holmes Street through Livermore and Vallecitos Road south of Pleasanton. SR 84 diagonally connects 1-680 to 1-580. First Street has a varied lane configuration and varied land uses along the length of its corridor. From I-580 to Portola Avenue, First Street is a six-lane road. From Portola Avenue to Holmes Street, First Street is a four-lane road with sidewalks, bike lanes, and a raised median. (In some locations the median becomes a two-way, left-turn lane or disappears entirely.) Parking is permitted along some sections of First Street. Holmes Street also has a varied lane configuration that changes from four lanes with sidewalks and median, to two lanes with a wide painted median and sidewalk, to two lanes with no median. The land use varies from light commercial to residential to rural. Bike lanes are present where the street narrows to two lanes. Vallecitos Road is a two- lane winding, rur~l road that passes through mostly undeveloped farm land and hills. Routes of Regional Significance in Livermore Area Vasco Road is a north/south arterial that is defined as a route of regional significance through Contra Costa County and Alameda County to its termination at Tesla Road in the City of Livermore. Vasco Road is a two-lane road along most of its length, except in developed areas near Lawrence Livermore National Laboratories where it widens to four lanes with concrete curbs, bike lanes, and a raised landscaped median. Stanley Boulevard is an east/west route that is defined as a route of regional significance from its intersection with First Street and Holmes Street in Livermore to its intersection with First Street in Pleasanton. Stanley Boulevard is four lanes along its entire length. Bike lanes are continuous along Stanley Boulevard except in the region near Shadow Cliffs Regional Recreation Area where the bike lanes convert into a two-way bike path on the south side of the road. First Street and Holmes Street are part of Route 84 (see above). Routes of Regional Significance in Pleasanton Area First Street is a two-lane, north/south route defined as a route of regional significance from Stanley Boulevard in the north, to Bernal Avenue in the south. North of downtown, First Street has bike lanes on both sides. Through downtown Pleasanton, First Street has a center turn lane, one lane each way. parking on both sides, and sidewalks. Sunol Boulevard is a north/south route defined as a route of regional significance from Bernal Avenue to its interchange with I-680. South of Bernal Avenue, Sunol Boulevard is four lanes with raised median, sidewalk, and bike lanes, with adjacent commercial and Final Tri -Valley Transportation Plan Adopted July 1995 14 Existing Transportation Conditions residential land uses. South of Junipero Street. Sunol Boulevard narrows to two lanes with no median. ' Santa Rita Road is a north/south route that is defined as a route of regional significance from its intersection with 1-580 in the north, to its intersection with Stanley Boulevard and Main Street near downtown Pleasanton. Santa Rita Road is a six-lane road with sidewalks and raised medians south of 1-580. At Valley Avenue, Santa Rita Road narrows to four lanes. A residential frontage road on the east side of Santa Rita Road exists in the segment between Valley Avenue and Stanley Boulevard. Main Street is the continuation of Santa Rita Road and is defined as a route of regional significance to Bernal Avenue. Main Street is a two-lane road with left-turn lanes at Ray Street/St. John Street, St. Mary, and Ray Street/Neal Street. Main Street has sidewalks and parking along both sides in the downtown area. Hopyard Road is a north/south route that is defined as a route of regional significance from its intersection with 1-580 to its intersection with Del Valle Parkway and Division Street. South of I-580 to Valley Avenue, Hopyard Road is a six-lane road with wide lanes, sidewalks, and a raised median. A right-turn lane exists between intersections at Owens Drive and Las Positas Boulevard on the east side (northbound direction) of the road. Between Valley Avenue and Division Street, Hopyard Road transitions from six lanes with median sidewalks and bike lanes, to a three-lane and then a two-lane road with an asphalt concrete path on the west side.

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 1-680, Hopyard Road north of Owens, San Ramon Road near 1~580, Dougherty Road near 1~580, and Dublin Boulevard west of 1-680. First Street in Pleasanton, however, is a downtown street, and congestion in this location is expected du,e to the dense development. 'Freeway Levels of Service Level of service descriptions for both 1-580 and 1-680 were obtained from the 1-680 Corridor Study Existing Conditions report prepared by TJKM: 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. 1-580 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 1-5801l-680 interchange and the Santa Rita Road/Tassajara Road interchange in Pleasanton. This section occasionally becomes congested during peak. hours. 1-680 operates at LOS C or better in both direc- tions throughout most of the Tri-Valley area. However, a section of northbound 1-680 between Stoneridge and the I-B801l-580 inter- change occasionally becomes congested during peak hours as does the southbound segment between Alcosta and the 1~680f[~580 interchange. All these problems on 1-580 and 1-680 near the 1-6801l-580 interchange are caused by the interchange design with loop , ramps and weaving sections. The other segments of 1-680 that occasionally become congested are from Crow Canyon, Road north to the 1-680/24 interchange. Intersection Levels of Service The operating conditions at intersections of routes of regional significance and at certain freeway off-lon-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).

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-Valleyarea 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 VascolI-580 EB Off-Ramp (LOS F). During the PM peak hour three intersections operate at Level of Service E or F: VascolI-580 WB Off, VascolI-580 EB Off, and DanvillelStone Valley.

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 ill 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 defIDed on the Tri-Valley Bike Plan ap- proved by the TVTC in February 1992. Final Tri -Valley Transportation Plan Adopted July 1995 28 Existing Transportation Conditions Trcnsit 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 (LA VTA), 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-ridebus 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 Progrcms 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. Final Tri -Valley Transportation Plan Adopted July 1995 29 Barton-Aschman Associates, Inc.

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 carpoollvanpool 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 ReductionlTravel 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 Final Tri -Valley Transportation Plan Adopted July 1995' 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. Exis~ing 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. Tl;1is 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 an.d Alameda countywide transportation plans, the Tri- VaUey 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 consistent with adopted Action Plans. Final Tri -Valley Transportation Plan Adopted July 1995 38 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 TSMlTDM program). · Circulation of environmental documents as specified in Action Plans. · 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 todays traffic conditions. For freeways, this corresponds to the existing CMP sta~dards. 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 1-580 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. Under current conditions, only three of the study intersections violate this standard. Tri-Valley Gateways. 1-580, 1-680, 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.) Average Vehicle Ridership (A VB). 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 A VR = 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 A VR for all employers, large and small, by 10 percent. Final Tri -Valley Transportation Plan Adopted July 1995 39 Goals and Transportation Service Objectives Transit Travel Times. Express transit options should be provided that equal or better auto travel times in the major corridors (1-680 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. Final Tri - Valley Transportation Plan Adopted July 1995 40 4. 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 transport~tion 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. Final Tri - Valley Transportation Plan Adopted July 1995 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 jurisdiction1s 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 improv-ement 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-5801I-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 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 wiU be built by developers to serve their development projects.

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). 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.

Overall, the baseline forecasts show 18,000 more employed residents than jobs, which would reinforce the Tri-Valley's existing pattern of net out- comm.uting. Table 4-3 Jobs Versus Workers (Baseline Growth Forecasts) Year Jobs Workers 1990 2000 2010 111,651 160,420 202.887 122,882 167,826 221,431 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 1-680, to 20 percent on 1~580 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, 1-580 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.

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, 1-680 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.

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 t9 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 aXe 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.

This would occur even with a jobslhousing 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. 1-680 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. , Final Tri - Valley Transportation Plan Adopted July 1995 80 Barton-Aschman Associates, Inc. o = LOS E or F Intersection = Congested Rood i LEGEND (Not to Scalc) Danville \ \ \ \ i JOHNS 101:! a ~ ------ cou0:1.

Final Tri -Valley Transportation Plan Adopted July 1995 96 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 be met at the gateways based on demand, without spending over $2 billion on transportation improvements-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. Final Tri -Valley Transportation Plan Adopted July 1995 98 Plan Alternatives Maximum Highway In~estment 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 (1-680, 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 (1-680, Altamont Pass and Vasco Road). Figure 6-5 shows the congested routes with the maximum transit alternative. Final Tri -Valley Transportation Plan Adopted July 1995 99 Barton-Aschman Associates, Inc.

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 tproducing 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. 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 (1-680, 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.

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 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. Higber 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. Growtb 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 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. Reduced LOS standards were also considered for arterials as part of the strategy for resolving TSO violations, as discussed on page 237 of the Plan. 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-Valleyrather 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 mayor 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 1-680 and 1-580 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. Final Tri - Valley Transportation Plan Adopted July 1995 117 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. Road Improvements .'i , 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 1-680 north and south, 1-580 east and west, Crow Canyon Road to Castro Valley, and Vasco Road. 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 meter~ng 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: 1-680 North. The section north of Diablo Road cannot practically be widened beyond the HOV lanes under construction. The gateway constraint assumption recognizes this reality. 1-680 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. Final Tri -Valley Transportation Plan Adopted July 1995 118 Recommended Improvement Plan 1-580 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. " 1-580 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 1-580 as a regional facility (see Chapter 7). The gateway constraint policy also applies to Patt~rson 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: · 1-680 to the north. Six lanes plus HOV lanes. · 1-580. Eight lanes. · 1-680 to the south. Six lanes plus HOV lanes. · Crow Canyon Road to Castro Valley. Two lanes. · Vasco Road north of 1-580. 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- Final Tri -Valley Transportation Plan Adopted July 1995 119 Recommended Improvement Plan ments 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. 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 uninetered 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. Final Tri -Valley Transportation Plan Adopted July 1995 120 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 1-680 and 1-580 in neighboring communities. Freeway HOV Lanes. High Occupancy Vehicle (HOV) lanes are under construction along 1-680 between Rudgear Road and 1-580. 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 1-580 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 1-680 and 1-580 are included in the plan. Due to the expense of the projects, however, some segments are included as lower priority projects. 1-680 south of 1-580 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 1-680 between Alcosta Boulevard and Route 84 should also be planned to include HOV lanes b~t with a lower funding priority. On 1-580, HOV lanes would be more difficult and costly to build because the inter- changes have not been built to accommodate them. However, the Caltrans Route Concept calls for 10 lanes plus BART in the median for 1-580. 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 1-580 in the Tri-Valley. To accommodate the extra freeway width, the interchanges at El CharrolFallon 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 1-580 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 1-580 west of Santa Rita Road is more problematic. With the BART extension and the I-580/I-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 1-580 west of Santa Rita are not included in the plan. Final Tri -Valley Transportation Plan Adopted July 1995 121 Recommended Improvement 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/I-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 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 Final Tri - Valley Transportation Plan Adopted July 1995 122 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 ServiceF in the year 2010. As much as the Plan calls for a policy limiting the capacity of Vasco Road to two 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: 1-680 north to Walnut Creek, Vasco Road to East County, and 1-680 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 Final Tri -Valley Transportation Plan Adopted July 1995 123 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. · 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 t-o 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. Contra Costa County Action Plans may include the following types of actions: Land Use Policy 1. Modify allowable densities for newly developing areas or areas wbere redevelop- ment is anticipated. 2. Cbange distribution of planned land uses (new or redeveloped) to reduce impacts on Regional Routes. 3. Probibit urban expansion in specified geograpbic areas. 4. Condition development approvals on progress in attaining traffic service objectives. . Capital Projects · Construction of new roads or transit facilities · Street or freeway widening · HOV lane construction · Adding turn lanes Final Tri -Valley Transportation Plan Adopted July 1995 124 Recommended Improvement Plan Operational Improvements · Traffic signal coordination · Ramp metering · Revisions to transit routes and schedules · Augmentation of bus service on Regional Routes Trip Reduction Programs · More stringent TDM requirements within corridor · Focused ridesharing campaigns · Parking limitations and charges Institutional Intergovernmental Programs · . Coordinated efforts to attract State and Federal funding for projects in the County. · Communication and cooperation with jurisdictions in adjacent counties. General Plan Amendments in Contra Costa County Tbe tools and procedures for conducting General Plan updates and analyzing proposed General Plan amendments will be the same as those used in preparing the Growth Management Elements.1 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. Tbe 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.2 IGrowth Management Implementation Documents, CCTA, December 1992, p.IG-51. 2Ibid., p. IG-52. Final Tri -Valley Transportation Plan Adopted July 1995 125 Recommended Improvement Plan 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 forany changes to the 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 for each jurisdiction. Any development reductions should be considered for their equitable effect on the development potential of the participating jurisdictions. Reductions should not create a "race" to develop, and if adopted, shall insure that jurisdictions with relatively greater development potential do not bear the full brunt of the development reductions. Also, the impact of this development reduction to traffic impact fees should be analyzed; other alternatives such as a toll road may also 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. The growth management study and any impact fees would each have to be approved unanimously. Violations or projected violations of TSO standards remaining after a growth management strategy is adopted shall be resolved as discussed on page 237 of the Plan. . 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 Final Tri -Valley Transportation Plan Adopted July 1995 126 Recommended Improvement Plan employed resident and vice versa will minimize the need for residents to leave the area for work. This will minimize the traffic pressure at the gateways. 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 SeNice Standards 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 todays volumes. This is true because growth in San Joaquin County, Santa Clara County, and 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, 1-680 b~tween Alamo and Route 84 is expected to flow smoothly. Level of.SerVice F conditions, however, are expected on 1-580 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 (TOM) 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 (A VR) 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 A VR 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. . Final Tri - Valley Transportation Plan Adopted July 1995 127 Recommended Improvement Plan 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 A VR for all employers. This increase would be realized through the adoption a~d enforce- ment of local trip reduction ordinances. The 10 percent increase in A VR will bring some of the intersections otherwise projected to be borderline unacceptable back into compliance with the TSOs. Road Improvement Plan The Tri-Valley Transportation Plan includes many road improvement projects. These 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. 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 TSOs through 2010. This list may be modified in subsequent studies.

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. 1-580 HOV Lanes. Completion of the HOV project on 1-580 from Livermore Avenue to the Alameda County border. 2. 1-680 HOV Lanes. Completion of the 1-680 HOV Lane project from 1-580 to Route 84. This would create a system of continuous HOV lanes on 1-680 through the Tri-Valley. 3. I-580/I-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. Final Tri -Valley Transportation pian Adopted July 1995 136 Recommended Improvement Plan 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 routes. For modeling purposes, specific bus routes were developed and tested. Howev- 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 seryice. 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 pew express bus routes operating in the 1-680, 1-580, and Vasco Road corridors. The following areas are served: Final Tri -Valley Transportation Plan Adopted July 1995 137 Barton-Aschman Associates, Inc.

Santa Clara County to San Ramon 4. Fremont to San Ramon 5. Brentwood to Pleasanton 6. Brentwood to Livermore 7. Fremont to Livermore 8. Hayward to Pleasanton 9. Hayward to Livermore 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 1-580 as a Critical Freight Route and 1-680 as a Major Freight Route. These designations are consistent with the Alameda County Long-Range Transporta- tion Plan. Truck volume studies show that 1-580 at the Altamont Pass carries more than 20,000 trucks each weekday while 1-680 at the Sunol Pass carries more than 15,000 trucks per day. As a Critical Freight Route, 1-580 should be accorded priority for intermodal funding . under ISTEA. Also, 1-580 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). A13 a Major Freight Route, 1-680 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 1-580 and 1-680. 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. Final Tri -Valley Transportation Plan Adopted July 1995 140 8. Financial Plan Implementation of the Tri-Valley Transportation Plan will be fiIlanced through a combination of public and private sources. The primary existing funding sources include the Measure C program in Contra Costa County and th~'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 County Measure 8 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 580/680 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. . Final Tri -Valley Transportation Plan Adopted July 1995 ,>'''~' 141 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 r,eceive 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.

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 Final Tri - Valley Transportation Plan Adopted July 1995 143 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, Van pools 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. · 1-680 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 1-680 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: Final Tri -Valley Transportation Plan Adopted July 1995 144 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. I-5801I-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 IlOV 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. 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. Final Tri -Valley Transportation Plan Adopted July 1995 145 Financlai 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. 1-580 HOV Lanes. Completion of the HOV project on 1-580 from Livermore Avenue to the San Joaquin County border. 2. 1-680 HOV Lanes. Completion of the 1-680 HOV Lane project from Alcosta Boule- vard to Route 84. This would create a system of continuous HOV lanes on 1-680 through the Tri-Valley. 3. 1-580/I-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.

The project list is subject to further discussion at the TvtC. 2 Assumes that one-half the cost will be paid by Area 4 (Tri-Valley) and one-half the cost by Area 3. Financial Plan 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 Final Tri -Valley Transportation Plan Adopted July 1995 148 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? . 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.

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.

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 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.

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 dis,cussed 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 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 Final Tri - Valley Transportation Plan Adopted July 1995 153 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 woul~ 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 I-580/I-p80 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. Table 8-7 Cost Estimates for Second Priority Regional Projects Project Cost (millions of current dollars) 1-580 HOV Lanes (N. Livermore Avenue to San Joaquin County Line) 1-680 HOV Lanes (Alcosta to Route 84) 1-580/1-680 Interchange- NB to WB Flyover Ramp Total $85 40 120 $245 Final Tri - Valley Transportation Plan Adopted July 1995 154 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 arid 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 impr.ovements. 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 arid 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. 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. Final Tri -Valley Transportation Plan Adopted July 1995 160 Executive Summary I 4. Install ramp metering at all freeway on-ramps, provided study shows metering would I 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 i 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. ,r 6. Support regional gasoline taxes to encourage commute alternatives and provide funds for needed transportation projects. I 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. I 8. Request that transit agencies conduct a study of the formation of a transit benefit district tp 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 1988 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"). Final Tri -Valley Transportation Plan Adopted July 1995 161 Executive Summary The following table shows jurisdiction responsibility by route.

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 for each jurisdiction. Any development reductions should be considered for their equitable effect on the development potential of the participating jurisdictions. Reductions should not create a "race" to develop, and if adopted, shall insure that jurisdictions with relatively greater development potential do not bear the full brunt of the development reductions. Also, the impact of this develop- ment reduction to traffic impact fees should be analyzed; other alternatives such as toll road may also 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. The growth management study and any impact fees would each have to be approved unanimously. Violations or projected violations of TSO standards remaining after a growth management strategy is adopted shall be resolved as discussed on page 237 of the Plan. Final Tri -Valley Transportation Pian Adopted July 1995 219 10. Plan Implementation, Monitoring, and Review This chapter describes how the Tri-Valley Transportation Plan will be implemented. Specific topics inClude plan adoption by member jurisdictions, collection of the subregional traffic impact fee, procedure for monitoring transportation service objec- tives, and procedures for handling development applications. Plan Adoption 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 ,3 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. 3JPA agreement included in Appendix C. Final Tri -Valley Transportation Plan Adopted July 1995 220 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 ErR 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, Axe 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. Axe interim fee measures needed while the above issues are resolved? Mter 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. Many 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, Final Tri - Valley Transportation Plan Adopted July 1995 221 Plan implementation, Monitoring, and RevIew Monitoring Transportation Service Objectives The Transportation Service Objectives (TSOs) are the heart of the TVTP. While certain growth assumptions are a part of the plan, they serve merely to guide the specification of a planned transportation system and financing program. 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 process set forth on page 237 of the Plan, 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, 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 D.S, Census and periodically from MTC, In between times, transit . Final Tri -Valley Transportation Plan Adopted July 1995 222 Plan Implementation, Monitoring, and Review 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 (A VR) and how it can be calculated. To calculate A VR, annual employee surveys, conducted by employers, will be necessary. In many places these are already being done, and due to air quality regulations, A VR 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. A VR 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 not 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 Techni.cal 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 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. Final Tri - Valley Transportation Plan Adopted July 1995 223 Plan Implementation, Monitoring, and Review 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- ment, 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, 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 as stated in the CCTA Growth Manage- ment Implementation Documents, page IG-52, 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 RTPs 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: 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. Final Tri -Valley Transportation Plan Adopted July 1995 224 Plan Implementation, Monitoring, and Review 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. I I , Development Review Procedures for General Plan Amendments in Contra Costa County. Any Tri-Valley area general plan amendment in Contra Costa County that generates 500 or more pealt-hour trips than is currently allowed by the applicable General Plan, shall be deemed consistent with this Action Plan if preceded or accom- panied by a multi-jurisdictional cooperative planning agreement that identifies the responsibilities of the participating parties to ensure that the subsequent approvals will not result in a violation of Traffic Service Objectives, Demonstration of compliance with TSOs shall include, but not be limited to, computer model runs that incorporate each jurisdiction's Five Year Capital Improvement Program of transportation projects and the projects of federal, state, and regional agencies such as Caltrans, transit operators, the Metropolitan Transportation Commis- sion, etc. In addition, the computer model database will include each local jurisdiction's anticipated land use development projects realistically expected to be constructed within the next five years. The Dougherty Valley Settlement Agreement fulfills this requirement fora multi- jurisdictional cooperative planning agreement for development in the Dougherty Valley area. The Contra Costa jurisdictions will consider entering into multi-jurisdic- tional cooperative planning agreements with Alameda County jurisdictions in the Tri- Valley area. 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, r I 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 1-580 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 plan will require a unanimous vote of all members of the TVTC. Final Tri -Valley Transportation Plan Adopted July 1995 225 Plan Implementation, Monitoring, and Review Conflict Resolution Because of the importance 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. 4. Majority vote of all members present required for action on any other matter. Future Role of MC It is anticipated that implementation of the Action Plan will rest primarily with the 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 Transportatio~ Plan · Development and implementation of a regional traffic impact fee · Coordinated implementation of Actions requiring interjurisdictional cooperation Final Tri -Valley Transportation Plan Adopted July 1995 226 Appendices Appendix A Description of VCCC Program Technical Procedures 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, Action 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 the capacity of an intersection. It represents the maximum number of vehicles that can pass through an intersection under prevailing traffic conditions. The CCT A 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 cate 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 desjgn capacities based on the 1.800 vehicles per hour saturation flow rate are frequently achieved within Contra Costa County, .,...........10 43 Technical Procedures As indicated in Table 8, the saturation flow rates varied by movement type, Exclusive left.tum 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 fDr 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, which uses 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 CCT A 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: c, = $, x (~); Where (for lane group or approach i) c, = &, - capacity in vehicles per hour; saturation flow rate in vehicles per hour; effective green time in seconds; and intersection cycle length in seconds. g - C = a:\IocIIprD.IO 45 I I , ~ I I , , I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Technical Procedures 7.3 SlJPPLEMENT AL ANALYSIS OF DELAY Because the CCT A 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 usin~ the CCT A'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. 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, -=.......10 46 Technical Procedures STEP 3: Phasing Identify 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 (Ve) - 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 (V J - the maximum number of left turns that can clear against opposing traffic volumes - is estimated using the following equation: VL = 1.200(~) - Vo Where: VL = G = C = Vo = left-turn volume, in vehicles per hour, that can clear during the green for opposing through traffic. maximum green plus yellow time, · cycle time for opposing through traffic. · sum of opposing through and right-turn volumes, in vehicles per hour. a:~.IO 47 I I I I I I (. I I I I I I I I I Technical Procedures I I I I I I I I I I I I I I I I I .. If either the maximum green time or the cy:ie 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 tums 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 to the turn volumes should be made prior to entering into -the program. STEP 6. Calculate Volume-la-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: . Right turn volumes from exclusive right turn lanes are adjusted for right turDS on red by the non-conflicting left turn volumes with a minimum reduction of 90 vehicles per hour, (Non-conflicting left tums go concurrently with the right turn. For example, the non-conflicting left turn for the northbound right turn is the westbound left turn.) . Oetennine the capacity of each movement and each combined movement from Table 9. -=........10 48 I Technical Procedures I . Calculate the ,volume-to-capacity ratio for each movement and combined movement by dividing the adjusted volumes by the capacities.

For a split phased direction, the I highest volume-to-capacity ratio from each of the approachs is chosen. Free right turns are Dot included in the calculation since they are not under signal control. Circular 212 does not clearly indicate how the critical movements are to be I 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.
