MERCED TO FRESNO: CENTRAL VALLEY WYE

 

Final Supplemental Environmental Impact Report/Environmental Impact Statement

The California High-Speed Rail Authority (Authority) has prepared the Final Supplemental Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the Central Valley Wye portion of the Merced to Fresno Section of the California High-Speed Rail (HSR) Project. The Final Supplemental 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 U.S. 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.

This Final Supplemental EIR/EIS was prepared as a supplement to the 2012 Final EIR/EIS for the Merced to Fresno Section of the California HSR Project (Merced to Fresno Final EIR/EIS), which was certified/approved by the Authority as CEQA lead agency and by the FRA as the NEPA lead agency.

Following completion of the Merced to Fresno Final EIR/EIS in May 2012, the Authority and FRA approved portions of the “Preferred Alternative” (i.e., the Hybrid Alternative) outside the wye for the north-south HSR alignment and the Downtown Merced and Downtown Fresno Mariposa Street station locations. Both agencies deferred a decision on the area known as the “wye connection,” which refers to the HSR connection between the east-west San Jose to Merced Section to the west and the north-south Merced to Fresno Section to the east, to allow for additional environmental analysis. This Final Supplemental EIR/EIS is the next step in the environmental review process for the Authority to select a wye connection. This document evaluates the impacts and benefits of implementing a wye connection in the geographically limited area of the wye connection between the cities of Merced and Madera. It is based on additional project planning and engineering that has occurred over the last several years.

As CEQA lead agency, the Authority prepared and released the Draft Supplemental EIR/EIS in May 2019. In July 2019, the Authority received NEPA Assignment from the FRA, as noted above. The Authority, as NEPA lead agency, released the Draft Supplemental EIR/EIS (the same document as under CEQA) to satisfy the NEPA public comment and review period in September 2019. Responses to public comments received during the CEQA and NEPA review periods are part of this Final Supplemental EIR/EIS and included in Volume IV.

After publication of the Draft Supplemental EIR/EIS, the Authority learned of a new listing of a bumblebee species, Crotch bumble bee (Bombus crotchii), as a candidate for the California Endangered Species Act that may be present in the relevant resource study area for the Central Valley Wye alternatives. As a result, pursuant to both CEQA and NEPA, the Revised Draft Supplemental EIR/Second Draft Supplemental EIS (Revised/Second Draft Supplemental EIR/EIS) was recirculated for a 45-day public comment period. Responses to comments received during the review period for the Revised/Second Draft Supplemental EIR/EIS are part of this Final Supplemental EIR/EIS and included in Volume IV.

This Final Supplemental EIR/EIS evaluates the No Project Alternative and four Central Valley Wye alternatives: the State Route (SR) 152 (North) to Road 11 Wye Alternative, SR 152 (North) to Road 13 Wye Alternative, SR 152 (North) to Road 19 Wye Alternative, and Avenue 21 to Road 13 Wye Alternative The Authority’s “Preferred Alternative” in this Final Supplemental EIR/EIS is the SR 152 (North) to Road 11 Wye Alternative.

Revised Draft Supplemental Environmental Impact Report/ Second Draft Supplemental Environmental Impact Statement, Biological Resources Analysis

The California High-Speed Rail Authority (Authority) announces the availability of a joint revised draft supplemental environmental impact report/environmental impact statement to address a bumble bee species that was recently listed as a state candidate species and may contain habitat within the Central Valley Wye study area.

This document was prepared pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA), and is entitled “Merced to Fresno Section: Central Valley Wye Revised Draft Supplemental Environmental Impact Report/Second Draft Supplemental Environmental Impact Statement, Biological Resources Analysis” (referred to below as “Revised/Second Draft Supplemental EIR/EIS”). The Revised/Second Draft Supplemental EIR/EIS was prepared as a limited revision to the previously published Draft Supplemental Environmental Impact Report and Environmental Impact Statement (Draft Supplemental EIR/EIS), a supplement to the 2012 Final EIR/EIS for the Merced to Fresno Section of the California High-Speed Rail Project (Merced to Fresno Final EIR/EIS), which was certified/approved by the Authority as the CEQA lead agency and by the Federal Railroad Administration (FRA) as the NEPA lead agency.

Following the Authority’s publication of the Draft Supplemental EIR/EIS for CEQA purposes in May 2019 and subsequent publication of the Draft Supplemental EIR/EIS for NEPA purposes in September 2019, the Authority learned of the new listing by the State of California Department of Fish and Wildlife of a bumble bee species that may be present in the relevant resource study area for the Central Valley Wye alternatives. The Authority, as lead CEQA and NEPA agency for the Central Valley Wye, is issuing this Revised/Second Draft Supplemental EIR/EIS limited to the portions of the Draft Supplemental EIR/EIS that would require revision based on the new information about the candidate species. New information includes background information, methodology, impact analysis, and mitigation measures.

The section and appendix comprising the Revised/Second Draft Supplemental EIR/EIS are:

  1. Section 3.7, Biological Resources and Wetlands
  2. Section 3.19.6.6, Cumulative Impacts, Biological Resources and Wetlands
  3. Appendix 3.7-C-2, Biological Resources and Wetlands Special-Status Wildlife

The Authority reviewed other sections of the Draft Supplemental EIR/EIS and found, based on research and a review of the evidence, that no other substantive changes would be required, including Section 3.19, Cumulative Impacts.

Revised/Second Draft Supplemental EIR/EIS

Draft Supplemental Environmental Impact Report/Environmental Impact Statement

The California High-Speed Rail Authority (Authority) announces the availability of a draft supplemental environmental impact statement pursuant to the National Environmental Policy Act (NEPA) entitled “Merced to Fresno Section: Central Valley Wye Draft Supplemental Environmental Impact Report/Environmental Impact Statement” (referred to below as “Draft Supplemental EIR/EIS”). This document was prepared as a supplement to the 2012 Final EIR/EIS for the Merced to Fresno Section of the California High-Speed Rail Project (Merced to Fresno Final EIR/EIS), which was certified/approved by the Authority as California Environmental Quality Act (CEQA) lead agency and by the Federal Railroad Administration (FRA) as the NEPA lead agency. The present Draft Supplemental EIR/EIS contains all the content required by CEQA and NEPA, however, the CEQA portion of this document was presented to the public in May and June of 2019.

On July 23, 2019, Governor Newsom executed a Memorandum of Understanding (MOU) with 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, 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 as NEPA lead agency is therefore issuing the Draft Supplemental EIR/EIS pursuant to NEPA only at this time for public and agency comments. Content in the Draft Supplemental EIR/EIS that is specific or pertaining to CEQA is for information only at this time.

Following its certification of the Merced to Fresno Final EIR/EIS in May 2012, the Authority approved portions of the “Preferred Alternative” (Hybrid Alternative) outside the wye for the north/south alignment of the high‐speed rail and the Downtown Merced and Downtown Fresno Mariposa Street station locations. The FRA made a similar decision. Both agencies elected to defer a decision on the area known as the “wye connection” – that is, the east-west HSR connection between the San Jose to Merced Section to the west and the north-south Merced to Fresno Section to the east, to allow for additional environmental analysis. This Draft Supplemental EIR/EIS is the next step in the NEPA environmental review process for the Authority to select a wye connection. This document evaluates the impacts and benefits of implementing a wye connection in the geographically limited area of the wye connection between the cities of Merced and Madera and is based on additional project planning and engineering that has occurred over the last several years.

The Preferred Alternative in this Draft Supplemental EIR/EIS, is the State Route (SR) 152 (North) to Road 11 Wye Alternative. This Draft Supplemental EIR/EIS also evaluates the No Project Alternative and four Central Valley Wye alternatives: the SR 152 (North) to Road 13 Wye Alternative, SR 152 (North) to Road 19 Wye Alternative, and Avenue 21 to Road 13 Wye Alternative.
