Project Environmental Evaluation

A full environmental analysis for Link21, as required by federal and state laws, will be performed during later phases of the Link21 Program. However, the Link21 Team is planning ahead so that all current and future work supports and complies with the environmental process. 

All Link21 planning activities, alternatives analyses, and stakeholder engagement will be done to identify potential environmental, social, and community issues well before the formal environmental process begins.  

National Environmental Policy Act (NEPA)

NEPA requires federal agencies to consider and disclose the effects of their actions on the quality of the human and natural environment. Because federal funding is anticipated for Link21, NEPA will apply to the Program.

NEPA requires federal agencies to prepare a detailed statement on proposed projects, which includes analyses of:

  • Environmental impacts of the proposed action
  • Potential mitigations for adverse impacts
  • Adverse impacts that cannot be avoided

Stakeholders, including public agencies, Tribal nations, and the public, will be involved in the Link21 NEPA process.  

California Environmental Quality Act (CEQA)

CEQA requires public agencies to regulate activities that may affect the quality of the environment so that major consideration is given to preventing damage to the environment.

CEQA applies to all governmental agencies at all levels in California, including local agencies, regional agencies, state agencies, boards, districts, and commissions. BART and Capitol Corridor will be the lead agencies for the CEQA process.
