California High-Speed Rail Authority (Authority) は、公的機関およびコミュニティの利害関係者と継続的に協力して、既存の施設、土地利用、環境資源、およびコミュニティへの潜在的な影響をさらに回避または最小化する設計への改良を組み込みました。その結果、2020 年に当局は、環境レビュー プロセスに含まれる追加のビルドの代替案を開発しました。

These additional alternatives are based on the prior Build Alternatives Refined SR14, E1 and E2, but have been modifi­ed to reduce potential impacts to sensitive aquatic resources south of Palmdale, including Una Lake.

The additional build alternatives are referred to as SR14A, E1A and E2A. The prior alternatives of Re­fined SR14, E1 and E2 are included in the environmental review for a total of six build alternatives that are analyzed in the Environmental Impact Report/Environmental Impact Statement (EIR/EIS). The EIR/EIS addresses many topic areas, including traffic, air quality, noise, vibration, aesthetics and more.

州の優先代替品: SR14A

The alternative determined to best balance trade-offs between environmental, community, performance, operations, and construction factors is known as the Preferred Alternative. For the Palmdale to Burbank Project Section, the State’s Preferred Alternative, SR14A, is approximately 38 miles long and connects the cities of Palmdale and Burbank. It will partially use the existing Metrolink right-of-way to the extent possible for approximately three miles in the San Fernando Valley. The Preferred Alternative would avoid crossing Una Lake and minimizes impacts to nearby wetlands. Trains operating along the Preferred Alternative would be underground through the community of Acton, the Angeles National Forest and the San Gabriel Mountains National Monument. SR14A is also underground where it crosses the Pacifi­c Crest Trail, avoiding impacts to the trail. Through the northern portion of the San Fernando Valley, SR14A is in a tunnel and emerges near the Hansen Dam Spreading Grounds, and then follows the Metrolink/Union Pacifi­c corridor to Burbank.
