Document Description
The proposed project is located on State Route 254 in Humboldt County. The project begins north of US 101 at post mile (PM) 0.00 and ends 1.9 miles north of Holmes Flat Road at PM 43.00. The purpose of the project is to rehabilitate existing drainage systems to good condition, reduce sediment loads to the Eel River and South Fork Eel River, and remediate fish passage barriers. The project is needed to repair failed drainage systems, prevent potential roadway damage resulting from drainage system failures, and to reduce sediment to the Eel River and South Fork Eel River. The existing damaged culverts deliver sediment to the Eel River and South Fork Eel River (which are both currently listed as an impaired water body that exceeds the Total Maximum Daily Load (TMDL) for sediment. The project proposes to rehabilitate drainage systems, which would include placing or replacing drainage inlets (DI), headwalls, armoring, downdrains, gravel, stream restoration at Chadd Creek and Mowry Creek, and upsizing or extending culverts, where applicable.
