8 Culverts via CIPP off SR 52

Caltrans District 11 is forecasting a project to repair eight culverts on State Route 52 in San Diego County, specifically between 0.1 miles east of the 805 and 52 separation and 0.2 miles west of the Santo Road overcrossing. The project utilizes Cured-in-Place-Pipe (CIPP) lining, a process involving the insertion, pulling, inflation, and curing of a flexible liner to harden the culverts. The scope of work includes the use of vactor trucks for cleaning, CCTV/Cure trucks for video inspection and curing, and service trucks for unrolling the liner. Work adjacent to culvert end treatments will be limited to personnel on foot using hand tools, with equipment parked on paved areas. The project requires shoulder, lane, and ramp closures to provide contractor access to drainage inlets, though no detours are necessary. There are no requirements for temporary construction easements, permits to enter, or permanent acquisitions. From a regulatory standpoint, the project is classified under NAICS code 237310 and has been determined to be exempt under CEQA categorical exemption 15301 for the repair and maintenance of existing facilities. It also qualifies as a categorical exclusion under NEPA with no significant environmental impacts. Key personnel associated with the project include Project Manager Van Nguyen and Environmental Scientist Emery McCaffery.
