This project is continuing work begun and funded in FY 1997-98. Phase V - Upper Sacramento Area Levee Reconstruction Project. The project will restore Sacramento River Flood Control Project levees northwest of Sacramento along the Sacramento River and Colusa Basin Drainage Canal to original design standards. The Corps' May 1995 Initial Appraisal Report identified a total of 13 miles of levees susceptible to seepage, subsidence, instability and partial collapse. Repairs to two of the five identified sites are economically justifiable based on the Corps' criteria.
Construction work is contingent upon execution of cost sharing agreements and funding.
The Corps is unwilling to fund work on several sites based on an incremental economic analysis. However, a systemwide benefit analysis clearly supports reconstruction of the levees. In the Upper Sacramento Area phase of the System Evaluation two of the three flood hazard areas are not economically justified based on an incremental analysis as separable elements. Federal interest should be based on a system-wide approach. The project was designed and constructed to function as a total system and it is not possible to separate individual components and still have a fully functioning system.
