6 Culverts via CIPP off I-805

Caltrans District 11 is seeking a contractor to repair six culverts on Route 805 in San Diego County, specifically between the Balboa Avenue overcrossing and 0.1 miles south of the La Jolla Village Drive overcrossing. The project utilizes Cured-in-Place Pipe (CIPP) Liner technology, which involves inserting a flexible liner into the upstream culvert end treatment, pulling it through to the downstream end, and then inflating and curing the liner to harden it. The work is classified under NAICS code 237310. The project will require shoulder, lane, and ramp closures to provide necessary access to culvert end treatments, though no detours, temporary construction easements, permits to enter, or permanent acquisitions are required. From an environmental and regulatory standpoint, the project is exempt under CEQA Section 15301 as maintenance of existing structures and is categorically excluded under NEPA regulations. All work must comply with the Environmental Commitments Record regarding biological, cultural, and visual resources, hazardous materials, and NPDES/Stormwater standards. Key personnel associated with the project include Emery McCaffery as the Environmental Scientist, Van Nguyen as the Project Manager, and Mitchell Doucette as the Senior Environmental Planner.
