SACRAMENTO, Calif. - The U.S. Army Corps of Engineers Sacramento District has awarded a $10.8 million contract to Raito Inc. of San Leandro, Calif., for improvements to the Marysville ring levee in Marysville, Calif.
The contract, funded by the American Recovery and Reinvestment Act of 2009 (ARRA), covers installation of a 105-foot slurry wall in the levee's fragile northeast reach. Slurry walls, buried vertically in the levee's center, help to prevent water from seeping through a levee, adding stability.
"This construction project is the first of several phases that will eventually significantly reduce flood risk for the city of Marysville," said Corps project manager Mark Ellis.
Slurry wall construction is scheduled to be complete by November 2011.
Installing the slurry wall is the first of four phases of the Marysville Ring Levee Project, a partnership of the Marysville Levee District, the California Central Valley Flood Protection Board, and the U.S. Army Corps of Engineers to upgrade the 7.6-mile levee that surrounds the city of Marysville. The project is scheduled to be completed in late 2013, at a projected cost of $100 million.
The U.S. Army Corps of Engineers Sacramento District provides flood risk reduction, navigation, watershed planning and ecosystem restoration services in parts of eight western states, including California, Nevada, Utah, Arizona, Colorado, Idaho, Oregon and Wyoming.
