Notice of Extension of Comment Period for Palmdale to Burbank Project Section Draft EIR/EIS:

The California High-Speed Rail Authority (Authority) has approved a 30-day extension of the public review period for the Draft Environment Impact Report/Environmental Impact Statement (EIR/EIS) for the Palmdale to Burbank Project Section. The Draft EIR/EIS for the Palmdale to Burbank Section has been available to the public on the Authority website since September 2, 2022. While a minimum 45-day review period is required for this document, pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA), the Authority had initially allowed for 60 days of public review. The new deadline for receipt of public comment was December 1, 2022.

The Palmdale to Burbank Project Section Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) will be available for a public review period pursuant to the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) beginning September 2, 2022 and ending November 1, 2022 December 1, 2022. 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.

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 NEPA lead agency. The Authority is also the lead agency under CEQA.

A Statewide Program (Tier 1) EIR/EIS was completed in 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 that 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 intercity travel demand in California increases, in a manner sensitive to and protective of California’s unique natural resources. A second program-level (Tier 1) EIR/EIS was completed in 2008 focusing on the connection between the Bay Area and Central Valley; the Authority revised this document under CEQA and completed it in 2012. Based on the Program EIR/EISs, the Authority selected preferred corridors and station locations to advance for further study.

The Authority has prepared a project-level (Tier 2) EIR/EIS that further examines the Palmdale to Burbank Project Section. The approximately 31-38 mile Project Section would provide HSR service between Palmdale, near the vicinity of Spruce Court just west of Sierra Highway in the north, and the Burbank Airport Station in the south. This HSR station would provide links with regional and local mass transit services as well as connectivity to airports and the highway networks within Los Angeles County. The Project Section would connect the Northern and Southern portions of the Statewide HSR system.

This Draft EIR/EIS evaluates the impacts and benefits of a No Project Alternative and six Build Alternatives. The Authority’s Preferred Alternative under NEPA, which serves as the proposed project for CEQA, is the SR14A Build Alternative. The Preferred Alternative would follow an alignment that heads southwest from Spruce Court in the city of Palmdale through the Angeles National Forest, including the San Gabriel Mountains National Monument, and then continues into the San Fernando Valley where it would connect with the approved Burbank Airport HSR station.

The purpose of environmental documents is to disclose information to decision makers and the public. While the science and analysis that supports 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 the Palmdale to Burbank Draft EIR/EIS.

The Executive Summary, available in English, Spanish, Armenian, and Arabic, 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.

Chapter 2.0, Alternatives, describes the proposed Palmdale to Burbank six Build Alternatives and the No Project Alternative used for purposes of comparison. It contains illustrations and maps and provides a review of construction activities. This chapter identifies the preferred alternative, which also serves as the proposed project for CEQA.

These first two chapters help the reader understand what is being analyzed in the remainder of the document.

Chapter 3.0, Affected Environment, Environmental Consequences, and Mitigation Measures, is where the reader can find information about the existing transportation, environmental, and social conditions in the area of Palmdale to Burbank. This chapter provides the findings of the analysis of potential environmental impacts, along with methods to reduce these impacts (called mitigation measures).

Chapter 4.0, Section 4(f)/Section 6(f) Evaluation, provides the analysis to support determinations made 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 5.0, Environmental Justice, discusses whether the Palmdale to Burbank Project Section Build Alternatives will cause disproportionate impacts on low-income and minority communities. It also identifies mitigation to reduce those impacts where appropriate.

Chapter 6.0, Project Costs and Operations, summarizes the estimated capital and operations and maintenance costs for the Palmdale to Burbank Build Alternatives evaluated in this Draft EIR/EIS.

Chapter 7.0, Other NEPA/CEQA Considerations, summarizes the Palmdale to Burbank Build Alternative’s environmental effects under NEPA, the significant adverse environmental effects that cannot be avoided under CEQA, and the significant irreversible environmental changes that would occur as a result of the project or irretrievable commitments of resources or foreclosure of future options.
