Document Description
The California Department of Transportation (Caltrans) proposes multiple drainage improvements within a 1.5-mile-long section of U.S. Route 101 in Monterey County from just north of the Crazy Horse Canyon Road/Echo Valley Road overcrossing (at post mile 98.8) to the northernmost intersection with Dunbarton Road (at post mile 100.3). Improvements would be implemented through joint repair and/or a complete replacement, depending on the conditions at each location. Existing culverts would be replaced with reinforced concrete pipes. Most of the replaced culverts would be upgraded to larger diameter drainage pipes for increased discharge capacity and reduced water flow velocity. Culvert replacements would use either the cut and cover method or the trenchless pipe jacking method. Existing drainage inlets would be replaced with new drainage inlets that meet current design standards. New flared end sections would be installed on the inlets and outlets of culverts as needed to prevent erosion. Concrete headwalls would be removed and replaced as needed. Damaged shoulder embankment slopes would be repaired at the outlets of two culverts. Two drainage channels would be graded to remove excess silt and vegetation.
