Title:
1. Folsom Dam Safety and Flood Damage Reduction EIS/EIR************************************************** 2. Folsom Dam Safety and Flood Damage Reduction Supplemental Environmental assessment/Initial Study
Site: www.usbr.gov/mp/jfp/index.html
Summary:
1. Reclamation seeks to improve public safety downstream of Folsom Dam by modifying the dam and its appurtenant structures. To mitigate potential safety concerns identified in previous and ongoing corrective action studies, potential modification alternatives will address a combination of hydrologic, seismic, and static issues of the Folsom Dam complex, which includes the Main Folsom Dam, Mormon Island Auxiliary Dam, the two wing dams and eight dikes. Potential modification alternatives include but are not limited to construction of an auxiliary spillway, dam and embankment raises, seismic retrofitting of structures, and dam and embankment static options. A major component of the project will be to locate and extract adequate borrow materials for embankment modifications.**************************************************************** 2. The purpose of the Supplemental EA/IS is to describe and analyze the effects of construction actions and revisions to the project since the release of the Folsom DS/FDR Final EIS/EIR. The Folsom DS/FDR Project, as approved and authorized, is currently under construction. This document does not change the project originally described in the Joint Federal Project (JFP) Record of Decision (ROD) and Safety of Dams (SOD) ROD, but proposes revisions to certain project actions that require further environmental analysis.
