Project: Lower Elkhorn Basin Levee Setback

Description: Consistent with the CVFPP 2012 plan and the Sacramento River Basin-wide Feasibility study, the Lower Elkhorn Setback Levee Project expands the capacities of the Yolo Bypass and Sacramento Bypass. Located just north of Sacramento, this project runs from east to west on the north side of the Sacramento Bypass and continues north along the east side of the Yolo Bypass terminating just south of I-5. This project provides the design, engineering, permitting, real estate acquisition, and construction of approximately 7 miles of setback levees that improve flood system capacity and provide opportunities for ecosystem enhancement consistent with the CVFPP. This project provides improved public safety for approximately 780,000 people in the Lower Sacramento River Basin area by increasing system capacity and reducing flood stages in the urban areas of Woodland, West Sacramento, and Sacramento. The setbacks also improve ecosystem function by adding approximately 1,800 acres of inundated floodplain habitat that is compatible with agriculture. Total project amount includes State support costs for project implementation.
