Project Section Environmental Documents

The California High-Speed Rail Authority (Authority) has prepared the Final Environmental Impact Report (EIR)/Environmental Impact Statement (EIS) for the San Francisco to San Jose Project Section (Project Section, or project) of the California High-Speed Rail (HSR) System. The Final EIR/EIS has been prepared and is being made available pursuant to both the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA).

The environmental review, consultation, and other actions required by applicable federal environmental laws for this project are being or have been carried out by the State of California pursuant to 23 United States Code 327 and a Memorandum of Understanding (MOU) dated July 23, 2019, and executed by the Federal Railroad Administration (FRA) and the State of California. Under that MOU, the Authority is the project’s lead agency under NEPA. Prior to the July 23, 2019 MOU, the FRA was the federal lead agency. The Authority is also the project’s lead agency under CEQA.

Following the Authority’s publication of the Draft EIR/EIS in July 2020, monarch butterfly (Danaus plexippus) became a candidate for listing under the federal Endangered Species Act (FESA) on December 15, 2020 (85 Federal Register 81813, December 17, 2020). This action by the U.S. Fish and Wildlife Service makes monarch butterfly subject to the definition of special-status species used by the Authority for analysis: “Plants or wildlife listed or proposed for listing as threatened or endangered under FESA (16 U.S.C. § 1531 et seq.)”. Monarch butterfly is assumed to be present in the resource study area for the project alternatives, based on historical records and existence of suitable habitat for the species. In addition, the Authority developed the Millbrae Station Reduced Site Plan Design Variant (RSP Design Variant) to address stakeholder concerns by analyzing a smaller, potentially feasible footprint for the station design at this location. The RSP Design Variant preserves HSR track and platform right-of-way needs but reconfigures station facilities, parking, and station access to reduce impacts on existing and planned development. As a result, pursuant to both CEQA and NEPA, the Authority published a Revised/Supplemental Draft EIR/EIS in July 2021 to address potential impacts on monarch butterfly and evaluate the environmental impacts of the RSP Design Variant. Responses to comments received during the review periods for both the Draft EIR/EIS and the Revised/Supplemental Draft EIR/EIS are provided in Volume 4 of this Final EIR/EIS.

Brief Explanation of Each Volume and Chapter

Volume 1: Report

Chapter 1, Project Purpose, Need, and Objectives, explains the Authority’s Purpose and Need for the San Francisco to San Jose Project Section and provides a history of the planning process.

Chapter 2, Alternatives, describes the proposed project alternatives, as well as the No Project Alternative, used for purposes of comparison. It contains illustrations and maps and provides a review of construction activities. These first two chapters help the reader understand what is being analyzed in the remainder of the document.

Chapter 3, Affected Environment, Environmental Consequences, and Mitigation Measures, is where the reader can find information about the existing transportation, environmental, and social conditions in the vicinity of the Project Section. This chapter provides the findings of the analysis of potential environmental impacts, along with methods to reduce these impacts (called mitigation measures).

Chapter 4, Section 4(f)/6(f) Evaluation, provides the analysis to support the Authority’s determinations under Section 4(f) of the Department of Transportation Act of 1966 and Section 6(f) of the Land and Water Conservation Fund Act.

Chapter 5, Environmental Justice, discusses whether the project alternatives may cause disproportionate impacts on low-income and minority communities. It also identifies mitigation to reduce those impacts where appropriate.

Chapter 6, Project Costs and Operations, summarizes the estimated capital and operations and maintenance costs for each project alternative evaluated in this Final EIR/EIS.

Chapter 7, Other CEQA/NEPA Considerations, summarizes the project alternatives, the significant and unavoidable environmental impacts under CEQA, adverse environmental effects that cannot be avoided under NEPA, and the significant irreversible environmental changes that would occur as a result of the project alternatives or irretrievable commitments of resources or foreclosure of future options.

Chapter 8, Preferred Alternative, describes the Preferred Alternative and the basis for identifying it.

Chapter 9, Public and Agency Involvement, contains summaries of coordination and outreach activities with agencies and the general public during preparation of this Final EIR/EIS.

Chapter 10, Distribution List, identifies the public agencies, tribes, and organizations that were informed of the availability of, and locations to review, this Final EIR/EIS.

Volume 4: Responses to Comments on the Draft EIR/EIS and Revised/Supplemental Draft EIR/EIS
This volume includes comments received on the Draft EIR/EIS and Revised/Supplemental Draft EIR/EIS during the review periods for each document, and the responses to those comments.

The California High-Speed Rail Authority (Authority) announces the availability of a limited revision to its previously published Draft Environmental Impact Report (EIR)/Environmental Impact Statement (EIS) for the San Francisco to San Jose Project Section of the California High-Speed Rail (HSR) Project. This document is entitled San Francisco to San Jose Project Section Revised Draft Environmental Impact Report/Supplemental Draft Environmental Impact Statement (Revised/Supplemental Draft EIR/EIS). The Revised/Supplemental Draft EIR/EIS has been prepared and is being made available pursuant to both the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA). The environmental review, consultation, and other actions required by applicable federal environmental laws for this project are being or have been carried out by the State of California pursuant to 23 United States Code (U.S.C.) Section 327 and a Memorandum of Understanding (MOU) dated July 23, 2019, and executed by the Federal Railroad Administration (FRA) and the State of California. Under that MOU, the Authority is the project’s lead agency under NEPA. Prior to the July 23, 2019, MOU, the FRA was the federal lead agency. The San Francisco to San Jose Project Section Revised/Supplemental Draft EIR/EIS will be available to the public on July 23, 2021. Pursuant to Section 15088.5, subdivisions (c) and (f)(2) of the CEQA Guidelines, the Revised/Supplemental Draft EIR/EIS is limited to the portions of the previously published Draft EIR/EIS that require revision. Other information that has not been revised, including the methods for evaluating impacts under NEPA and the methods for determining significance under CEQA, as well as appendices, can be found in the Draft EIR/EIS. The previously published Draft EIR/EIS, including Section 3.7, Biological and Aquatic Resources; Section 3.18, Cumulative Impacts; and Chapter 12, References, is available on this website. The Authority requests that reviewers limit the scope of their comments to the revised information in the Revised/Supplemental Draft EIR/EIS. This Revised/Supplemental Draft EIR/EIS has been prepared and is being made available pursuant to both CEQA and NEPA and presents a new biological resources analysis for monarch butterfly and an analysis of a design variant for the Millbrae Station, neither of which were included in the Draft EIR/EIS. Biological Resources—New Special-Status Species Following the Authority’s publication of the Draft EIR/EIS in July 2020, monarch butterfly (Danaus plexippus) became a candidate for listing under the federal Endangered Species Act (FESA) on December 15, 2020 (85 Federal Register 81813, December 17, 2020). This action by the U.S. Fish and Wildlife Service makes monarch butterfly subject to the definition of special-status species used by the Authority for analysis: “Plants or wildlife listed or proposed for listing as threatened or endangered under FESA (16 U.S.C. § 1531 et seq.)”. Monarch butterfly is assumed to be present in the resource study area for the project alternatives, based on historical records and existence of suitable habitat for the species. As this is a new potential impact not included in the Draft EIR/EIS, the Authority determined that the analysis of this impact should be included in a recirculated document. Accordingly, Section 3.7 in the Revised/Supplemental Draft EIR/EIS includes additional analysis and revised and new mitigation measures related to monarch butterfly. Millbrae Station Reduced Site Plan Design Variant The Authority developed the Millbrae Station Reduced Site Plan Design Variant (RSP Design Variant) to address stakeholder concerns by analyzing a smaller, potentially feasible footprint for the station design at this location. The RSP Design Variant preserves HSR track and platform right-of-way needs but reconfigures station facilities, parking, and station access to reduce impacts on existing and planned development. The RSP Design Variant differs from the design of the Millbrae Station evaluated in the Draft EIR/EIS (Millbrae Station Design) by: eliminating surface parking lots on the west side of the alignment that would have served as replacement parking for displaced Caltrain and Bay Area Rapid Transit parking spaces; relocating the new HSR station entrance hall; eliminating lane modifications to El Camino Real; and eliminating the California Drive extension north of Linden Avenue to El Camino Real from the project. The RSP Design Variant would apply equally to either project alternative—Alternative A or Alternative B. Because the RSP Design Variant is a potentially feasible alternative different from the Millbrae Station Design that would lessen some significant environmental impacts of the project, the Authority determined that the analysis of the RSP Design Variant should be included in a recirculated document. Accordingly, Section 3.20, Millbrae Station Reduced Site Plan Design Variant, in the Revised/Supplemental Draft EIR/EIS evaluates the environmental impacts of the RSP Design Variant. Revised Draft Environmental Impact Report/Supplemental Draft Environmental Impact Statement Consistent with the guidance provided under CEQA and NEPA,[1] the Authority, as lead CEQA and NEPA agency for the San Francisco to San Jose Project Section, is issuing the Revised/Supplemental Draft EIR/EIS limited to the portions of the Draft EIR/EIS that require revision based on the new information described above. New information includes background information, a description of the RSP Design Variant, methodology, impact analysis, and mitigation measures. To the extent practicable, a vertical line in the margin indicates a substantive change in the text since publication of the Draft EIR/EIS; minor editorial changes and clarifications are not identified. The Revised/Supplemental Draft EIR/EIS consists of excerpted text where updates or additions related to monarch butterfly have been made within Section 3.7 and Section 3.18. In these sections, ellipses are used to identify where text from the Draft EIR/EIS remains unchanged and, therefore, is not included in the Revised/Supplemental Draft EIR/EIS. The Revised/Supplemental Draft EIR/EIS also includes a new Section 3.20 that evaluates the environmental impacts of the RSP Design Variant and presents new information not included in the Draft EIR/EIS. All tables in the Revised/Supplemental Draft EIR/EIS present only information related to the new or updated analysis. The sections and appendices comprising the Revised/Supplemental Draft EIR/EIS are:

• Section 3.7, Biological and Aquatic Resources
• Section 3.18, Cumulative Impacts
• Section 3.20, Millbrae Station Reduced Site Plan Design Variant
• Chapter 12, References
• Appendix 3.7-A, Special-Status Species Potentially Affected
• Appendix 3.7-B, Scientific Nomenclature

The Authority reviewed other sections of the Draft EIR/EIS and found, based on research and a review of the evidence, that no other substantive changes would be required for this Revised/Supplemental Draft EIR/EIS. All other appendices to Section 3.7, as well as all technical reports supporting Section 3.7 of the Draft EIR/EIS, thus remain unchanged.

NEXT STEPS

The Authority anticipates publishing the Final EIR/EIS in spring 2022. The Final EIR/EIS will include the Authority’s responses to the comments received on the previously circulated Draft EIR/EIS, in addition to responses to comments received on the Revised/Supplemental Draft EIR/EIS. Section 3.7 includes new mitigation measures that will be incorporated into the Mitigation Monitoring and Enforcement Plan to be included as part of the CEQA/NEPA decision documents. After publishing the Final EIR/EIS, the Authority Board of Directors will consider whether to certify the Final EIR and approve the preferred alternative pursuant to CEQA. The Authority, as NEPA lead agency, will also consider whether to issue a Record of Decision approving the preferred alternative. [1] CEQA Guidelines, Section 15088.5; 40 Code of Federal Regulations (C.F.R.) Section 1502.9(c)(1)(ii) (1978). The Council on Environmental Quality (CEQ) issued new regulations, effective September 14, 2020, updating the NEPA implementing procedures at 40 C.F.R. Parts 1500–1508. However, because this project initiated the NEPA process before September 14, 2020, it is not subject to the new regulations. The Authority is relying on the regulations as they existed prior to September 14, 2020. Therefore, all citations to CEQ regulations in this document refer to the 1978 regulations, pursuant to 40 C.F.R. Section 1506.13 (2020) and the preamble at 85 Federal Register 43340.

The public review period for the San Francisco to San Jose Project Section Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) closed on September 9, 2020. The California High-Speed Rail Authority (Authority) will consider all comments received on the Draft EIR/EIS and respond to substantive comments on the Draft EIR/EIS in the Final EIR/EIS, scheduled for release in 2021. The Draft EIR/EIS was originally made available for a minimum 45-day public review beginning on July 10, 2020 and ending on August 24, 2020, pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). In response to agency and stakeholder requests and in consideration of limitations caused by the novel coronavirus pandemic, the Authority elected to extend the public review period to September 9, 2020. On July 23, 2019, Governor Newsom executed a Memorandum of Understanding (MOU) with the Federal Railroad Administration (FRA) under the Surface Transportation Project Delivery Program (known as NEPA Assignment), pursuant to the legal authority under 23 U.S.C. section 327. Under NEPA Assignment, the State of California, acting through the California State Transportation Agency and the Authority, has assumed FRA’s responsibilities under NEPA and other federal environmental laws, as assigned by FRA under the MOU. These responsibilities that California will now carry out, pursuant to 23 U.S.C. section 327 and the MOU, include environmental review, consultation, and other actions required by applicable Federal environmental laws for this project. The Authority is therefore both the CEQA and NEPA lead agency. The Preferred Alternative in the Draft EIR/EIS is Alternative A, a predominantly two-track blended system with no additional passing tracks that includes service at one future station (Salesforce Transit Center, which would serve as an HSR station when the Transbay Joint Powers Authority completes its Downtown Extension Project), three existing Caltrain stations to be shared by HSR and Caltrain (4th and King Street [an interim station only], Millbrae, and San Jose Diridon), and the East Brisbane LMF. As part of ongoing design optimization, a design variant has been identified to optimize speeds for the San Jose Diridon Station and approaches in Alternative A. The Authority will consider whether to formally adopt Alternative A (with or without the San Jose Diridon Station design variant) as they prepare and certify the Final EIR/EIS.

Document Organization

The purpose of environmental documents is to disclose information to decision makers and the public. While the science and analysis that support this Draft EIR/EIS are complex, this document is intended for the general public. Every attempt has been made to limit technical terms and the use of acronyms. The terms and acronyms are defined the first time they are used and a list of acronyms and abbreviations is provided in Chapter 15 of this document. The Summary, available in English, Spanish, Vietnamese, Chinese, and Tagalog, provides an overview of the substantive chapters. It includes a table listing the potential environmental impacts for each environmental resource topic and directs the reader to where additional information can be found elsewhere in the document.

Brief Explanation of Each Chapter

Volume 1 – Report

Chapter 1, Project Purpose, Need, and Objectives, explains the Authority’s Purpose and Need for the San Francisco to San Jose Project Section and provides a history of the planning process. Chapter 2, Alternatives, describes the proposed project alternatives, as well as the No Project Alternative, used for purposes of comparison. It contains illustrations and maps and provides a review of construction activities. These first two chapters help the reader understand what is being analyzed in the remainder of the document. Chapter 3, Affected Environment, Environmental Consequences, and Mitigation Measures, is where the reader can find information about the existing transportation, environmental, and social conditions in the vicinity of the Project Section. This chapter provides the findings of the analysis of potential environmental impacts, along with methods to reduce these impacts (called mitigation measures). Chapter 4, Section 4(f)/6(f) Evaluation, provides the analysis to support the Authority’s determinations under Section 4(f) of the Department of Transportation Act of 1966 and Section 6(f) of the Land and Water Conservation Fund Act. Chapter 5, Environmental Justice, discusses whether the project alternatives may cause disproportionate impacts on low-income and minority communities. It also identifies mitigation to reduce those impacts where appropriate. Chapter 6, Project Costs and Operations, summarizes the estimated capital and operations and maintenance costs for each project alternative evaluated in this Draft EIR/EIS. Chapter 7, Other CEQA/NEPA Considerations, summarizes the project alternatives, the significant and unavoidable environmental impacts under CEQA, adverse environmental effects that cannot be avoided under NEPA, and the significant irreversible environmental changes that would occur as a result of the project alternatives or irretrievable commitments of resources or foreclosure of future options. Chapter 8, Preferred Alternative, describes the Preferred Alternative and the basis for identifying it. Chapter 9, Public and Agency Involvement, contains summaries of coordination and outreach activities with agencies and the general public during preparation of this Draft EIR/EIS. Chapter 10, Distribution List, identifies the public agencies, tribes, and organizations that were informed of the availability of, and locations to review, this Draft EIR/EIS. Chapter 11, List of Preparers, provides the names and responsibilities of the authors of this Draft EIR/EIS. Chapter 12, References, lists references and contacts cited in writing this Draft EIR/EIS. Chapter 13, Glossary of Terms, provides definitions of certain terms used in this Draft EIR/EIS. Chapter 14, Index, provides a tool to cross-reference major topics addressed in this Draft EIR/EIS. Chapter 15, Acronyms and Abbreviations, defines the acronyms and abbreviations used in this Draft EIR/EIS.

Volume 2 – Technical Appendices

Appendices provide additional details on the project alternatives and the Draft EIR/EIS process. The technical appendices are primarily related to the affected environment and environmental consequences analyses. These appendices are numbered to match their corresponding section in Chapters 2 and 3 of this Draft EIR/EIS (e.g., Appendix 3.7-A is the first appendix for Section 3.7, Biological and Aquatic Resources).

Volume 3 – Preliminary Engineering Plans

These are detailed design drawings, including trackway, stations, structures, roadway crossings, maintenance facilities, and systems.
