May 2, 2008 - The Bureau of Reclamation has awarded the second in a series of construction contracts for Dam Safety Modifications at Folsom Dam and Reservoir. The contract, awarded on April 28, 2008, in the amount of $3,204,790.00, went to DD-M Crane and Rigging of Alameda, California.
Reclamation's Safety of Dams (SOD) Program is continuing a multi-year construction program to perform required safety modifications at Folsom Dam and Reservoir in conjunction with the ongoing Joint Federal Project (JFP). The JFP represents an unprecedented partnership among Reclamation, the U.S. Army Corps of Engineers, the Central Valley Flood Protection Board, and the Sacramento Area Flood Control Agency to address the hydrologic risk to Folsom Dam identified through SOD evaluations. Hydrologic risk refers to the possible overtopping of Folsom Reservoir's dams and dikes during an extreme storm event. The JFP will also achieve the Corps' objective of increasing flood control at Folsom to 1/200-year protection.
As part of the SOD Program, modifications will be made to Dike 5, an earthen embankment feature located between Dikes 4 and 6 on the north shore of Folsom Reservoir, near the intersection of Auburn-Folsom Road and Eureka Road in Granite Bay. The principal work to be performed includes the partial removal of the downstream face of Dike 5 in order to add features such as filters and drains to control internal erosion. The filters and drains will be constructed of high-quality imported materials that will be obtained commercially and brought onsite via trucks. Supplemental material will be excavated from a borrow site within the reservoir bottom close to Dike 5.
Site preparation, including trail relocation, development of the contractor use area, and installation of contractor access off Auburn-Folsom Road, will begin this month and continue until approximately September 1, 2008 (Labor Day). Principal construction work on Dike 5 is anticipated to begin after Labor Day, with completion expected in Spring 2009. Some construction activities will be limited to certain times of the year to maintain dam safety and operational/ recreational requirements.
As construction details become available, Reclamation will provide this information on the Safety of Dams website and on the JFP website. Construction schedules are subject to change due to weather conditions and other unforeseen circumstances, and the websites will be updated to reflect any schedule changes.
