The Chabot Dam Upgrade Draft Environmental Impact Report (EIR) will be released for public review in late 2013, and a public hearing will be held during the 45-day review period. Written comments on the draft EIR will be addressed in the final EIR. The EBMUD Board of Directors will formally certify the final EIR and approve the project in spring 2014. The California State Department of Water Resources Division of Safety of Dams (DSOD) will also need to approve the project.
The EIR is being prepared by staff and consultants, and will identify two dam alternatives: soil treatment (cement deep soil mixing) and conventional earthwork. After the EIR is complete, EBMUD staff will recommend a preferred alternative based on costs, environmental impacts, and public and resource agency comments.
