California High-Speed Rail Project: San Francisco to San Jose Project Section

California High-Speed Rail Project: San Francisco to San Jose Project Section

The California High-Speed Rail Authority (Authority) previously certified a Statewide Program Environmental Impact Report (EIR)/Environmental Impact Statement (EIS) (Tier 1) in November 2005 as the first phase of a tiered environmental review process for the proposed California High-Speed Rail (HSR) System planned to provide a reliable, high-speed, electric-powered rail system that links the major metropolitan areas of the state and delivers predictable and consistent travel times. A further objective is to provide an interface with commercial airports, mass transit, and the highway network and to relieve capacity constraints of the existing transportation system as increases in intercity travel demand in California occur, in a manner sensitive to and protective of California’s unique natural resources. Based on the Statewide Program EIR/EIS, the Authority selected preferred corridors and station locations to advance for additional study. The Authority prepared an EIR/EIS that further examines the San Francisco to San Jose Project Section (Project Section) at the project level (Tier 2) within San Francisco, San Mateo, and Santa Clara Counties. The Project Section analyzed in the EIR/EIS includes approximately 43 to 49 miles of blended system infrastructure with Caltrain and up to 6 miles of dedicated HSR infrastructure (depending on the alternative and viaduct option), extending from the 4th and King Street Station in San Francisco to West Alma Avenue in San Jose. The project alternatives analyzed are divided into the following geographic subsections: San Francisco to South San Francisco, San Bruno to San Mateo, San Mateo to Palo Alto, Mountain View to Santa Clara, and San Jose Diridon Station Approach. The San Jose Diridon Station Approach Subsection was fully analyzed as part of the San Jose to Merced Project Section EIR/EIS and this analysis was incorporated into the San Francisco to San Jose Project Section EIR/EIS to support a station-to-station analysis with logical termini for the San Francisco to San Jose Project Section. The decision on a Preferred Alternative within the San Jose Diridon Station Approach Subsection between Scott Boulevard in Santa Clara and West Alma Avenue in San Jose occurred as part of the environmental approvals process for the San Jose to Merced Project Section and was approved by the Authority on April 28, 2022, through resolutions #HSRA 22-10, #HSRA 22-11, and #HSRA 22-12. Through Resolution #HSRA 22-20, the Authority has approved the San Francisco to San Jose Project Section Preferred Alternative (Alternative A with modified Caltrain stations for HSR at the 4th and King Street and Millbrae Stations, the East Brisbane light maintenance facility, the Millbrae Station Design, and associated facilities) from the 4th and King Street Station in San Francisco to Scott Boulevard in Santa Clara.
