Fish Passage Improvement & Stream Channel Modification

The contract entails the engineering and construction of modifications to the stream channel at the Cloverdale Road crossing to restore and enhance fish passage for coho salmon and steelhead trout. Work may include adjusting or replacing existing culverts, installing grade control structures to stabilize stream gradients, and creating natural riffle-pool sequences that mimic healthy stream conditions. The goal is to remove barriers to fish migration and improve ecological function within the watershed, aligning with regional conservation priorities for native aquatic species. The project is classified under NAICS code 237990 for other heavy and civil engineering construction and is issued as a subcontract under the jurisdiction of California’s Fish and Wildlife, Region 3 – Bay Delta, based in Fairfield. It was posted on May 28, 2026, and is associated with Project ID 2023090380. While the exact location within California is not specified, performance is expected to occur at the Cloverdale Road crossing, with all work designed to meet biological and hydraulic standards for effective fish passage. No set-aside provisions or small business preferences are indicated, and the scope is focused solely on aquatic habitat restoration through targeted stream channel engineering.
