Climate Change Vulnerability Analysis for Live Oak Canal and Gilsizer Slough Drainage Districts

The Sutter County Development Services Department is soliciting proposals for a professional consultant to perform a climate change vulnerability analysis for the Live Oak Canal and Gilsizer Slough Drainage Districts in Yuba City, California. The project requires a comprehensive evaluation of existing roadway crossings, including culverts and bridges, and their connected open channels to determine their ability to convey anticipated flows based on the latest state climate and precipitation prediction models. Key tasks include conducting a structural stability and erosion potential assessment, performing a condition survey of the drainage system, importing survey data into the County's GIS system, and producing a Final Hydraulics Report and a Vulnerability Analysis report for approval by the Sutter County Board of Supervisors. Proposals are due by November 24, 2026, and will be evaluated based on project understanding, scope of work, project manager qualifications, demonstrated competence, and client references. Notably, cost proposals are not required during the initial phase; the top-ranked consultant will submit a cost proposal following a scoping meeting. The contract requires compliance with California Prevailing Wage Laws and DIR registration. The final project acceptance by the Board of Supervisors is tentatively scheduled for April through May 2028. Invoices for services are payable within thirty days of approval, and the project is managed by Neal Hay, Director of Development Services.
