Document Description
Yolo County is proposing the Knights Landing Flood Management Project to reduce flood risks associated with flooding from the Sacramento River and the Knights Landing Ridge Cut in and around the community of Knights Landing. The proposed flood improvements would strengthen approximately 3.78 miles of the surrounding levees of the Knights Landing Basin and build resiliency into the Knights Landing Basin levees. The Proposed Project intends to attain a 100-year level of flood protection for the community of Knights Landing and to reduce the flood risk to the Knights Landing Basin while sustaining the agricultural economy, providing safe access to the river, and improving the riverine habitat viability. The proposed improvements along the Sacramento River Right Bank Levee include addressing under-seepage and through-seepage by constructing cutoff walls, drained stability berms, or combination stability-seepage berms, addressing slope stability by widening the levee crown and stabilizing/flattening the landside slopes and addressing freeboard deficiencies by widening and raising the levee. The proposed Knights Landing Ridge Cut improvements include approximately 1.2 miles of improvements to the existing landside levee to improve stability.
