Phase IV - Lower Sacramento Area Levee Reconstruction Project. The project will restore Sacramento River Flood Control Project levees south of Sacramento along the Sacramento River, its tributaries and distributary sloughs, and the Yolo Bypass to original design standards. The Corps' October 1993 report has identified a total of 43 miles of levees susceptible to seepage, subsidence, instability and partial collapse. Repairs to four of the fourteen identified flood hazard areas are economically justifiable based on the Corps' incremental economic analysis criteria. The economically feasible work consists of stabilizing and raising levees along Miner, Elk, Steamboat, and Sutter Sloughs.
Construction work is contingent upon execution of cost sharing agreements and funding.
The FEAT recommends the Legislature provide the Reclamation Board funds to support the Corps construction of necessary levee repairs under Phase IV of the Sacramento River Flood Control System Evaluation. 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.
