Oroville Dam FCO Radial Gate Seismic Retrofit (OM-OFD-2026-002)

The California Department of Water Resources is initiating the Oroville Dam FCO Radial Gate Seismic Retrofit project, identified by solicitation number OM-OFD-2026-002. The primary objective is to repair and retrofit all eight radial gates at the Oroville Dam Flood Control Outlet to ensure they meet specific seismic criteria. The scope of work includes reinforcing gate arms with carbon fiber reinforced polymer followed by grouting, re-coating the skin plates, and replacing trunnion pins and bushings. Construction activities will require the use of a crane to lift the gates, with the requirement that the crane remains within the gate bay throughout the process. The project is located in Oroville, Butte County, specifically at Oroville Dam Road and Canyon Drive, with all access, staging, and work occurring within the DWR right of way. This effort is classified as a forecast under NAICS code 237990. From an environmental standpoint, the project has been granted a Notice of Exemption under CEQA Class 1 for existing facilities, as it is considered necessary maintenance that does not result in significant environmental impacts. Primary points of contact for the project include Environmental Scientist Janine Beck and Environmental Program Manager Sara Lowry.
