CALIFORNIA — Following a high water event in 2006, levee sites near highway 80 and the Yolo Bypass began to slump, essentially sinking into the foundation beneath it. The U.S. Army Corps of Engineers recently completed repairs on the second of those two sites, adding a gravel drain and reconstructing a 2,000-foot stretch of levee. The Corps completed a similar 400-foot levee piece in 2009 as part of the West Sacramento Project, a joint effort with the West Sacramento Area Flood Control Agency and the Central Valley Flood Protection Board to improve the levees surrounding West Sacramento.
