Dogtown Road over Indian Creek Bridge Replacement Project Initial Study/MND

The Dogtown Road over Indian Creek Bridge Replacement Project involves the replacement of existing bridge 30C0051 in Calaveras County, California. Under Streambed Alteration Agreement CAL-65720-R2 and pursuant to section 1602 of the Fish and Game Code, the project will install a new structure in the same location that is approximately 2 feet higher and 40 feet longer than the original. The construction scope includes the use of spread footings or short cast-in drill hole piles socketed into rock, the creation of two excavation areas for abutment construction measuring 35 feet wide by 15 feet long by 12 feet deep, and the placement of rock slope protection and construction fill within the Indian Creek channel. Additionally, roadway approaches will be widened and adjusted to align with the grade of the new bridge. The project is managed by Calaveras County and was reviewed by the California Department of Fish and Wildlife, which determined that the project would not have a significant environmental effect within its permitting jurisdiction. This determination is supported by a mitigated negative declaration, and the execution of the project is contingent upon the implementation of specific mitigation measures as conditions of approval. The project is categorized under NAICS code 237310 for highway, street, and bridge construction.
