The U.S. Army Corps of Engineers (Corps) announces the availability of a Draft Environmental Impact Statement (EIS) for the Whittier Narrows Dam Safety Modification Study, Los Angeles County, California for review and comment. Pursuant to the National Environmental Policy Act (NEPA). The Corps has prepared a Draft EIS for the Whittier Narrows Dam Safety Modification Study (DSMS). The Draft EIS evaluates risk management plans (alternatives) to remediate safety concerns such as overtopping and seepage. The Draft EIS describes and analyses the impacts of risk management plans (RMPs) that are formulated, evaluated and compared through the DSMS process in order to identify a recommended RMP that reduces risks to downstream life-safety and property associated with dam failure. Implementation of the recommended risk management plan would mitigate the intolerable Dam safety risk and allow the Dam to safely function as originally intended and authorized. Without this action, the Dam could fail resulting in life-threatening floods to downstream communities. The Proposed Action is needed to provide life-safety to the communities downstream of the Whittier Narrows Dam.
