10-1L660 Alpine County State Route 4 Drainage System Restoration Project

The California Department of Transportation is undertaking the Alpine County State Route 4 Drainage System Restoration Project to replace or rehabilitate 14 existing culverts along State Route 4 in Alpine County. Work will involve regrading inlet and outlet channels, installing rock slope protection, and upgrading or replacing end treatments and headwalls to improve drainage functionality and mitigate erosion. The project requires the removal of riparian vegetation, including mature trees, and is being conducted under a Streambed Alteration Agreement issued by the California Department of Fish and Wildlife pursuant to Fish and Game Code section 1602, ensuring compliance with environmental protections for state waterways. The project is forecasted with a posted date of July 6, 2026, and is managed by Caltrans District 10 in Stockton. Primary correspondence is handled by Haqiqat Kalirao as the Project Proponent, with Samantha Morford of the California Department of Fish and Wildlife serving as the environmental liaison. The project will be executed within California, and further details are accessible through the CEQA Net project portal linked in the contract data.
