Environmental Planning

Whenever large projects like the high-speed rail program are being planned, certain requirements must be met. Some of these requirements include state and federal environmental rules and laws. These rules and laws guide high-speed rail program planners to look carefully at how the program might impact the environment. They must also find ways to reduce those impacts when possible.

As we continue to environmentally clear all project sections from San Francisco to Los Angeles/Anaheim, the Authority prepares Environmental Impact Report/Environmental Impact Statement (EIR/EIS) reports to share our findings. We release drafts of these documents to the public so that we can get your feedback. But how do you read them? See a brief overview of these documents, what you will find, and how to leave your comments in the video below.
