Abstract : The Sacramento District, Corps of Engineers, has been authorized to conduct a comprehensive analysis of the long-term integrity of the levee system for the Sacramento River Flood Control Project. The project was authorized by the Flood Control Act of March 1917 and modified by various Flood Control and/or River and Harbor Acts in May 1928, August 1937, and August 1941. Additional modifications on Sacramento River and tributaries were authorized by the Flood Control Acts of December 1944 and May 1950 and incorporated under Sacramento River and Major and Minor Tributaries. Although construction of the project was initiated in 1918, many of the levees were originally constructed by local interests prior to that time and subsequently modified and adopted as part of the project. The Reclamation Board has participated as the local sponsor of the project and is responsible for the operation and maintenance of project facilities. This report is the third phase of the comprehensive analysis and evaluates about 240 miles of project levees along the Sacramento and Feather Rivers and their tributaries. The study area, north and west of the Sacramento Urban Area (first phase), covers portions of five counties: Placer, Solano, Sutter, Yolo, and Yuba. Studies indicate that sections of the project levees are susceptible to seepage and stability problems and do not provide the design levels of flood protection. Potential problems are primarily the result of sandy soils within the levee embankment and foundation. About 18.3 miles of reconstruction work is required to meet project design requirements at an estimated cost of $19.8 million. Between 2,000 and 3,000 people reside landward of the levees that need repair. Damageable property in those areas is estimated at $87 million. Reconstruction of the levees around the Robbins (R.D. 1500), Verona (R.D. 1001), Knights Landing, and Elkhorn areas would cost about $19.8 million.
