Corps awards $255.1 million contract for Folsom Dam spillway’s final construction phase

Published May 3, 2013

SACRAMENTO, Calif.  – The U.S. Army Corps of Engineers Sacramento District awarded a $255.1 million contract today to Kiewit Infrastructure West Co. of Fairfield to complete construction on the fourth phase of the new auxiliary spillway at Folsom Dam.

The award marks the beginning of the fourth and final construction phase of the spillway project, an approximately $900-million cooperative effort between the U.S. Bureau of Reclamation, Central Valley Flood Protection Board, Sacramento Area Flood Control Agency and the Corps to help reduce the Sacramento region’s flood risk.

“The Folsom Dam Joint Federal Project is absolutely vital to the safety of Sacramento County families and I’m pleased the Corps is awarding the phase four contract. Our region is at extraordinary risk for flooding and these important upgrades will help take pressure off our overburdened levees while keeping people who work and live in the region safe,” said U.S. Rep. Ami Bera, Elk Grove. “The project's continued implementation is a testament to what we can accomplish when we work together. Along with the Corps, I commend the Bureau of Reclamation, Central Valley Flood Protection Board, SAFCA, and other local and state entities, for their ongoing cooperation and partnership.”

“Today's contract announcement is a welcome step toward getting this crucial project done for the region,” said U.S. Rep. Doris Matsui, Sacramento. “The unique partnership between the Corps, Bureau of Reclamation, state of California and SAFCA will result in increased flood protection for the hundreds of thousands of people that rely on the Folsom Dam to protect them.  I will continue to work with my colleagues in Congress and the Administration to keep this critical project on schedule and on budget.”

The spillway will allow the Bureau of Reclamation to make more controlled water releases from Folsom Dam earlier during large storms. The Bureau of Reclamation completed most of the excavation for the spillway chute in the project’s first two phases. In May 2012, Granite Construction Company of Watsonville began construction on the project’s third phase: the spillway’s control structure, essentially a second dam. In phase four, the Corps will oversee Kiewit’s construction of a 3,027-feet-long spillway chute and stilling basin, as well as the 1,100-feet-long approach channel that connects the new spillway to the reservoir.

Construction is expected to begin July 1 and continue until summer 2017.

Six firms submitted proposals Feb. 25 for the phase four contract.
