High Speed Rail Grapevine Alignment Loses Support of HSRA

LEBEC, CA, The Grapevine (Monday, Jan. 9, 4:49 p.m.)—A press release has been issued by the High Speed Rail Authority (HSRA) regarding the Interstate 5 "Grapevine Alignment" option for the proposed California high speed rail line. At a time when the HSRA is under intense pressure for its own survival, the staff report reflects the intensive political lobbying and legal pressure exerted by Palmdale interests to maintain the "Palmdale Alignment." Here is the press release:


High-Speed Rail Releases I-5/Grapevine Study

Board to Vote Whether to Continue to Study I-5 or Take Staff Recommendation

Reinforcing 2005 Decision to Drop the I-5 Route in Favor of Antelope Valley Alignment

 SACRAMENTO, Calif. – California’s High-Speed Rail Authority should not consider a proposed route for the high-speed train along I-5 in southern California and instead should study a proposed route through Palmdale, according to the recommendations of a study released by the Authority staff today. The agency’s Board will consider the suggestion at its Jan. 12 meeting in Los Angeles.

 The Authority’s I-5 Conceptual Study, approved by the Board in May 2011, reinforces the 2005 Programmatic Environmental Impact Review and Environmental Impact Statement. It concludes that the Antelope Valley corridor still has fewer potential environmental impacts and greater connectivity than the I-5 corridor. The goal of the Study was to determine if a fresh look would reveal new conditions that would call for including an I-5 alignment in the Project Level EIR/EIS.

 Based on the Study, the Antelope Valley alignments were found to offer greater connectivity and accessibility to the fastest growing area of Los Angeles County. The alignments also provide greater opportunities for alignment variations through the mountains to avoid impacts to environmental resources. The high-speed train’s impact on urbanized land and farmland conversion due to growth would also be less than those on the I-5 corridor.

“Over the past several years, project-level work on the alignment between Bakersfield and Sylmar via Palmdale resulted in increased infrastructure costs because of the need for more tunnels and aerial structures than we initially estimated,” said Roelof van Ark, CEO, California High-Speed Rail Authority.

 “Because of this, a conceptual Study of the I-5 corridor was conducted to reassess assumptions and estimates," van Ark said, referring to the Statewide 2005 Program Environmental Impact Report/Environmental Impact Statement which advanced the Antelope Valley corridor. “The goal of this conceptual study was to review factors that changed since 2005 to ensure the most operationally successful alignment is being planned."

 The engineering team conducted several months of analysis that included extensive modeling to develop, identify and analyze alignments along the I-5/Grapevine corridor. The environmental review included an analysis of impacts on cultural and biological resources, wetlands and water bodies, growth- inducing impacts, national forests, farmland, and opportunities for using alignment variations to avoid impacting sensitive resources. The Study also analyzed constructability and cost issues and an evaluation of operational aspects, including ridership, operating costs and maintenance costs that were not compared qualitatively in the 2005 Program EIR/EIS.

The Study included intensive outreach to local agencies, cities, and communities to determine the local community impacts of these possible alignments. The Antelope Valley alignments continue to have strong stakeholder support based on the comprehensive outreach done during the Study process.
