Document Description
Caltrans proposes to rehabilitate 20 drainage systems and remediate fish passage barriers at two of the locations on U.S. 101 from post miles M0.0 to 46.5. Proposed work would include replacement of culverts, downdrains, drainage inlets, flared end sections, headwalls, end walls, and disturbed pavement. A new bridge (at PM 37.46), guardrail with concrete vegetation control strips, cable railing, rock slope protection, and rock-lined ditches would be installed. Work would also include vegetation removal, dewatering and water diversion, and revegetation. The project is needed to repair deteriorating or failing drainage systems to prevent erosion and potential roadway embankment failure, and to allow fish to access habitat necessary for survival and spawning.
