In early 2017, a 2.9 mile segment of levee adjacent to the City’s urban center (from approximately Gilsizer Slough south to Whiteaker Hall) showed signs of severe distress – such as seepage, sink holes and boils, and waterside erosion during winter/spring storm events and in the days following the Oroville spillway failure. Local agencies and the State averted potential disaster by aggressive flood fighting over a period of several weeks.
SBFCA had no plans to repair this stretch of levee, because the US Army Corps of Engineers had previously installed a slurry wall within it (2000). However, the poor performance of the slurry wall led SBFCA and the State to plan an emergency repair for completion before the next flood season. The US Army Corps of Engineers and the Central Valley Flood Protection Board expedited the approval of permits required for the project, allowing construction to begin August 2, 2017. Given the scope and scale of the repairs, construction will be completed by December 1, which is one month after the start of flood season.
The majority of the $28.5 million project is being paid for by the California Department of Water Resources
On behalf of Sutter County, SBFCA is conducting two separate Small Communities Flood Risk Reduction Feasibility Studies, one for the Tudor area in south Sutter County, and the other for the town of Sutter. The studies will include a summary of known flooding issues and problems with the existing flood management systems. Ultimately, the studies will determine a preferred flood risk reduction solution, to include potential funding sources to pay for implementation. The feasibility studies are fully funded under the CA DWR’s Small Community Flood Risk Reduction Program.
