Lower Deer Creek Flood and Ecosystem Improvement Project

Lower Deer Creek Flood and Ecosystem Improvement Project

The proposed project includes a variety of design measures, including levee setbacks, bank stabilization, flood easements, bridge improvements, diversion structure improvements, and levee improvements. Upstream of Red Bridge, setback and raised levees are proposed to improve flood protection. Downstream from Red Bridge to the Stanford-Vina Ranch Irrigation Company (SVRIC) Diversion Dam, bridge and levee improvements, coupled with levee setbacks, floodplain lowering, and flood easements, are proposed to convey higher flows and large wood through the bridge and to allow some natural channel migration and increased floodplain inundation and function. South of the SVRIC Diversion Dam, the dam access road would be improved and a canal cutoff structure installed to improve flood protection. Downstream of the dam to Highway 99, removal of non-USACE levees and berms is proposed to widen the floodway to allow greater flow conveyance, channel migration, and natural development of instream habitat. Improvements to USACE levees and installation of bank protection are also proposed just upstream of Highway 99 to maintain flood protection. Further downstream, levee improvements and a new levee are proposed to protect valuable existing pasture and infrastructure, and an easement is proposed to allow channel migration at the downstream end of the creek. In China Slough, grading, vegetation management, and culvert improvement are proposed to enhance conveyance through the slough.
