CALTRAIN EXTENSION TO MONTEREY COUNTYALTERNATIVES ANALYSISIn addition to lowering congestion on the roadways, the commuter rail extension would bring asignificant increase in ridership to both the existing Caltrain and the connecting Capitol Corridorservices. Other benefits to this new service include an increase in access to job opportunities, moretransportation alternatives for senior citizens and those with physical disabilities, increased access toeducational resources and health care in the San Francisco Bay Area.Currently in the Monterey County and San Francisco Bay areas, job distribution and worker housingdistribution patterns do not match. The northern counties of San Francisco and Santa Clara havelarge job surpluses, requiring approximately 117,000 non-San Francisco Bay Area residents to fill theavailable positions as of 2000 (Metropolitan Transportation Commission). This pull of workersgenerates a large volume of inter-regional commuter traffic, adding to highway congestion and airquality impacts.The U.S. Census for 2000 estimated that 18,073 persons living in Monterey County work in anothercounty. Of this number, more than 30 percent are employed within Santa Clara County or other BayArea counties. Available public transportation choices between Monterey County and Santa ClaraCounty are limited to three northbound bus trips (two Greyhound and one MST) during the AMcommute period and two southbound bus trips (one Amtrak Thruway and one MST) during theafternoon commute period. These buses are subject to traffic delays on U.S. 101 and SR 156.Development of Initial AlternativesAs part of this phase, a candidate pool of initial conceptual alternatives is developed to addressmobility problems and other concerns in the study area. This initial set of conceptual alternatives isstructured to provide a range of multi-modal transportation infrastructure and service improvements.The transportation alternatives emphasize candidate alignments and levels of investment and thusaddress different aspects of the study purpose and need. Included in the initial set of alternatives arebaseline alternatives which assume there is no new major transit capital investment and various buildalternatives which may include major investments in bus and/or rail transit technologies. For theMonterey County Fixed Guideway Study 1 , the conceptual alternatives considered included:• No Build Rail Service• Caltrain to Salinas Rail Service• Monterey Peninsula to San Francisco Intercity Rail Service• Monterey Peninsula to San Francisco Intercity Rail Service plus Caltrain to Salinas and MontereyPeninsula• Monterey Peninsula Passenger Rail Shuttle to Castroville Caltrain Service• Local Monterey Peninsula LRT (light rail transit) or BRT (bus rapid transit) Service• Salinas to Monterey Local Rail Service• Monterey Peninsula to San Francisco Intercity Rail plus Salinas to Monterey Local RailService• Enhanced Local Bus plus Monterey County to San Francisco Peninsula Express Bus Service(transportation system management (TSM))See Figure 1-5 for a brief description and location of the preliminary alternatives.1Combined study of the U.S. 101 Corridor and Monterey Peninsula elements.parsons CHAPTER 1: INTRODUCTION 9
CALTRAIN EXTENSION TO MONTEREY COUNTYALTERNATIVES ANALYSISScreening of Initial AlternativesThese eight alternatives were defined for capital cost estimating purposes. Capital cost information(Table 1-1), together with mode technology information, right-of-way utilization and potential stationrenderings, public involvement findings, and a qualitative evaluation of alternative performance (seeFigure 1-6), was presented to the Rail Policy Committee (RPC) in June 2005, along with a ProjectDevelopment Team recommendation of shortlisted alternatives showing strong potential forimplementation. This short list recommendation along with subsequent refinements and revisionswere discussed with RPC at their July, August, and September 2005 meetings along with individualbriefings with committee members on request.Following the shortlisting of conceptual alternatives for further refinement and evaluation, theAlternatives-Analysis study was divided into two projects; one to serve intra-county needs and one toserve inter-county (Monterey to San Francisco Bay Area) needs. This Alternatives Analysisdocument addresses the inter-county commute market alternatives.Two alternatives were defined to address the inter-county travel market: the Caltrain Extension toSalinas Alternative (Build Alternative) and the Express Bus Alternative (Transportation SystemsManagement (TSM) Alternative). Five additional alternatives were considered, but rejected. Theseincluded:• Shuttle bus service to Gilroy• Limited stop bus service to San Jose• Shuttle train service to Gilroy• Independent train service to San Francisco• Bus rapid transit service(These alternatives that were considered, but rejected, are discussed in Chapter 3 along with theBuild Alternative and the TSM Alternative.)As a result of this public involvement and policy review process, four alternatives emerged for furtherrefinement and testing. These four alternatives, labeled A through D, are listed below:A. Caltrain to Salinas Rail Service (four roundtrips on weekdays) and Intracounty BRTService (Monterey to Castroville and Marina to Salinas).B. Intracounty BRT/LRT Service (BRT from Monterey to north Marina and Marina to Salinas,LRT from Monterey to Castroville), Monterey Peninsula to San Francisco Intercity RailService (Monterey to San Francisco) and Caltrain to Salinas Rail Service (Commuter Rail).C. Intracounty LRT Service (local LRT from Monterey to north Marina, LRT extension fromNorth Marina to Castroville and Castroville to Salinas), Monterey Peninsula to San FranciscoIntercity Rail Service (passenger rail from Monterey to San Francisco) and Caltrain toSalinas Rail Service.D. Express Bus Service to San Francisco Peninsula (between Monterey County Transit Centersand Santa Clara, San Mateo and San Francisco County Caltrain Station Sets) and EnhancedLocal Bus Service (Monterey to Marina and Marina to Salinas).parsons CHAPTER 1: INTRODUCTION 10
