United States Army Corps of Engineers February 2014 – Federal Register Recent Federal Regulation Documents

The U.S. Army Corps of Engineers, Sacramento District (USACE) intends to prepare a Supplemental Joint Draft Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for the 2007 Folsom Dam Safety/Flood Damage Reduction EIS/EIR (hereafter referred to as the Project). USACE will serve as lead National Environmental Policy Act (NEPA) agency and the Central Valley Flood Protection Board (CVFPB) will serve as lead agency for compliance with the California Environmental Quality Act (CEQA). The Project was originally authorized in the 2004 Energy and Water Development Appropriations Act (EWDAA) and was later reauthorized in the 2007 Water Resources Development Act (WRDA). The Project is authorized for 4 components: (1) Emergency spillway gate modifications, (2) raising the right and left wings of the main dam, Mormon Island Auxiliary Dam (MIAD), and the reservoir dikes (1-8) by 3.5 feet, (3) temperature control shutter automation and reconfiguration, and 4) downstream ecosystem restoration of Bushy Lake and Woodlake. The Supplemental Draft Joint SEIS/SEIR will address two components of the authorized project, specifically the emergency spillway gate modifications and the 3.5 foot raise. These flood damage reduction components of the Project enhance the utilization of the existing surcharge flood storage space (temporary water storage space utilized during rare flood events), as well as increase the surcharge flood storage capacity of the reservoir.
