The Bureau of Reclamation is calling for proposals to help construct a new auxiliary spillway and repair wing dams at California’s 198.72-MW Folsom Dam as part of a plan to improve dam safety and increase flood protection for Sacramento. Bids are due July 9.
BuRec estimated the work would cost $25 million to $50 million.
In a final environmental impact statement issued earlier this year, BuRec and other agencies recommended building the auxiliary spillway and increasing the dam’s height as part of a preferred alternative for dam safety and flood control. (HNN 4/25/07)
The contractor selected from the solicitation will carry out excavation work for the auxiliary spillway and modify the Left Wing Dam and possibly the Right Wing Dam. Right Wing Dam might, or might not, be awarded as part of this solicitation.
BuRec said there are two options for the final configuration of the auxiliary spillway. One option includes a shallow, wide excavation for dam safety only. The other option, known as the Joint Federal Project because BuRec and the Corps of Engineers both would be involved, includes a deeper, narrower excavation. Work under the current contract would remove earth and rock required by either design, the government said.
BuRec is responsible for the dam’s safety, and the Corps is responsible for operating the project for flood protection.
