Union Pacific Railroad (UPRR) Canyon Subdivision Milepost 248.98 Bridge Replacement Project

The Union Pacific Railroad Canyon Subdivision Milepost 248.98 Bridge Replacement Project involves replacing a 60-foot-long, 72-inch-diameter corrugated metal pipe culvert with a 100-foot-long, 60-inch-diameter smooth steel pipe culvert installed via horizontal auger boring approximately six feet east of and parallel to the existing structure. All work will be conducted within the existing railroad right-of-way in Plumas County, California, with no encroachment beyond current boundaries. The new culvert will be stabilized at both inlet and outlet with riprap, while the original pipe will be grouted and left in place. Materials will be transported to the site by truck, and all removed materials will be hauled offsite. The project is subject to regulatory oversight under Clean Water Act Section 401 and Section 404, and is categorically exempt under CEQA Section 15302. The California Regional Water Quality Control Board, Region 5 – Redding, serves as the lead state agency, with the U.S. Army Corps of Engineers acting as the federal liaison.
