DescriptionAmerican River levee construction (6104055838).jpg | Workers dig down through a levee on the American River in Sacramento, Calif., Aug. 31, 2011 to expose underground utility pipes. Under the American River Common Features, funded in part by the American Recovery and Reinvestment Act of 2009, the U.S. Army Corps of Engineers Sacramento District is installing a slurry wall in the levee to help strengthen it and make it harder for water to leak through. The wall must be poured around the pipes, making it one of the more difficult reaches of Sacramento levees to improve. The levee will be restored to its original height once work is completed, scheduled for October. (U.S. Army Photo/Chris Gray-Garcia) |
