Big Tujunga Dam Seismic Rehabilitation, Los Angeles County, California (March 2006)
In accordance with the National Environmental Policy Act, FEMA has prepared a Final Environmental Assessment for the Big Tujunga Dam Seismic Rehabilitation to evaluate the impacts of the proposed action on the environment. The Los Angeles County Department of Public Works (LADPW) applied for FEMA Hazard Mitigation Grant Program funding to improve the dam and related facilities as part of the recovery from the Northridge earthquake of 1994. LADPW has identified the need to seismically strengthen the dam to remove the threat of failure during a significant seismic event. To address this hazard, LADPW proposes to reinforce the dam; modify the spillway, dam crest, and appurtenant structures; and put in place a new dam control system.
