Hennessey Reservoir Spillway Improvements

The City of Napa is soliciting subcontractors to undertake structural spillway improvements at Hennessey Reservoir, with the primary goals of enhancing safety, increasing hydraulic capacity, and implementing effective erosion control measures. This project is classified under NAICS code 237990, which covers other heavy and civil engineering construction, indicating the scope involves significant earthwork, concrete structures, and hydraulic engineering components. The work is scheduled to take place in Napa, California, with a posted date of June 8, 2026, and is not designated for any specific set-aside program, meaning it is open to qualified contractors regardless of size or ownership status. The contract is structured as a subcontract, suggesting that the primary contractor will be responsible for managing the overall project, with the awarded subcontractor handling specialized aspects of the spillway construction or rehabilitation. Performance will be localized to the reservoir site in the Napa area, identified by zip code 94559, and the project requires adherence to technical standards for dam and water control infrastructure. While no point of contact or funding source is listed, the inclusion of a public project link through CEQA Net indicates compliance with California environmental review protocols and provides a public portal for tracking project documentation and progress.
