HUM 254 Culvert Rehab

HUM 254 Culvert Rehab

This project proposes to address various locations along SR 254 (Avenue of the Giants) near Weott and Miranda and one location on U.S. Highway 101. 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 project proposes to construct two structures to provide fish passage, one at Chadd Creek and the other at Mowry Creek, rehabilitate 45 existing drainage systems (DS), and add two Transportation Management Systems (TMS). The work provided in this project is anticipated to decrease the risk of loss of roadway due to erosion or embankment failures within the roadway prism. 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 is currently listed as an impaired water body) that exceeds the Total Maximum Daily Load for sediment. Two failed drainage systems have resulted in fish passage barriers, preventing fish from access to habitat that is necessary for spawning and rearing. The purpose of the project is to rehabilitate existing drainage systems to good condition, reduce sediment loads to the South Fork Eel River, and remediate fish passage barriers.
