Program EIR/EIS Documents for the Statewide High-Speed Rail System (Tier 1)

The Authority has used a tiered environmental review process to support tiered decisions for the HSR system. Tiering of environmental documents means addressing a broad program in “Tier 1” environmental documents, then analyzing the details of individual projects within the larger program in subsequent project-specific or “Tier 2” environmental documents. The Authority and the Federal Railroad Administration prepared two Tier 1 documents for the statewide HSR system.
