San Joaquin River Multi-Benefit Project

The San Joaquin River Multi-Benefit Project, led by Reclamation District No. 341, involves the rehabilitation of approximately 3,800 linear feet of levee on Sherman Island in Sacramento County, California, between Stations 330+00 and 368+00. The primary objective is to meet the Delta-Specific PL 84-99 Standard for flood protection, requiring a 16-foot wide levee crest with a 2:1 waterside slope and a 3:1 landslide slope, maintaining 1.5 feet of freeboard above the 100-year Base Flood Elevation. The scope of work includes relocating existing power poles and overhead utility lines, removing the existing Sacramento County road, placing compacted embankment to raise the levee crown, constructing a landside levee toe berm for stabilization, and building a new County road. Additionally, the project will establish and maintain approximately 1 acre of hedgerow habitat consisting of riparian forest and scrub-shrub vegetation on the landside toe berm. Environmental compliance is managed through a Mitigated Negative Declaration, ensuring that biological, cultural, and tribal impacts remain less than significant. Special requirements include strict adherence to California Health and Safety and Public Resources codes regarding the inadvertent discovery of human remains, which mandates a 100-foot work stoppage and consultation with the Native American Heritage Commission and Most Likely Descendants. The project is supported by a Funding Agreement executed on July 3, 2024, with construction planned for 2027. Key administrative contacts include Martin Berber of Wagner & Bonsignore, Consulting Civil Engineers, and Robert Black, President of the agency.
