Document Description
The proposed project would rehabilitate 14 drainage systems on U.S. Highway 101 in Humboldt County and State Route 271 in Mendocino County. The purpose of the project is to restore the existing drainage facilities and prevent further damage to the surrounding roadbed. The project is needed because the culverts have exceeded their design life and are in need of repair. If not addressed, a collapse or blockage could occur causing flooding and further erosion to the roadbed. Work would include the repair and/or replacement of existing culverts, drainage inlets, headwalls, and the installation of new down drains, and rock slope protection.
