Permit No. 19941 – UPRR Sacramento Subdivision Mile Post 190.84 Bridge Replacement Project

Permit No. 19941 involves the replacement of the Union Pacific Railroad Bridge at Mile Post 190.84 on the Sacramento Subdivision crossing North Honcut Creek in Butte County, California. The project replaces an existing 315-foot long, 22-span Timber Stringer Trestle-Ballast Deck bridge with a new 332-foot long, 11-span prestressed concrete box bridge featuring a 17-foot-wide deck and 30-inch-deep boxes. Key operational activities include the excavation of 83 cubic yards of material to extend the bridge length, the placement of new rip rap, and the removal of existing bridge piers and six temporary culverts. The scope also requires the use of a temporary causeway and crane mats, with all excavated material to be disposed of outside the floodplain. The project is overseen by the Central Valley Flood Protection Board and Union Pacific Railroad, with administrative coordination managed by Jordan Robbins and Steve Cheney. This project has been granted a Notice of Exemption from the California Environmental Quality Act under statutory exemption 15275(a) and categorical exemptions 15302 and 15304, as it consists of replacing an existing structure and performing minor land alterations without significant environmental impact. The project is categorized under NAICS code 237310.
