Clipper Gap Crossing

The Clipper Gap Crossing project, managed by the Placer County Water Agency, involves the relining of approximately 1,470 lineal feet of underground pipeline crossing I-80 in Colfax, California. The scope of work includes the placement of a geopolymer or cure-in-place liner inside the existing pipe. Operations will be conducted on both sides of I-80, specifically near 15680 Lake Arthur Road and the intersection of Placer Hill Road and Applegate Road. Construction will take place within existing Caltrans and PCWA utility right-of-way, primarily utilizing a 20-foot corridor of paved roadway for work and staging. The project is expected to result in minimal ground disturbance, though some vegetation removal and tree trimming will be required. Classified under NAICS code 237110, the project is exempt from certain environmental reviews under Class 1, Section 15301, as it is categorized as the repair and maintenance of existing public facilities without expansion of use. Primary points of contact include Environmental Scientist Heather Trejo and Engineering Services Manager Steve Mikt.
