Document Description
The California Department of Transportation (Caltrans) proposes a maintenance project along State Route (SR) 20 in Mendocino County, at Post Mile (PM) 14.2-24.4, to replace eight culverts. The proposed maintenance project is state funded only. This project will replace drainage systems identified by the Culvert Inspection Program as deteriorated and beyond their useful service life. Without such replacement the roadway could be subject to washout requiring more extensive roadway reconstruction. All work will occur within the State right-of-way, and within the currently developed transportation infrastructure. The project maintains the original line, grade and purpose of the transportation facility. The project will not alter existing drainage patterns or increase runoff. Existing stormwater conveyance facilities will be replaced in-kind on the same alignment with minor design upgrades to culverts and inlets to comply with current design standards.
