The purpose of the Project is to provide fish passage and improve flood conveyance while providing and maintaining safe vehicle access across Potrero Creek to existing commercial facilities. The Project will remove a set of perched 48-inch corrugated metal culverts and concrete aprons and replace them with a single multi-plate arched culvert. The arched culvert will be approximately 23 feet long, have a 12-foot-10-inch span, 8-foot-4-inch rise and will provide a 16-foot roadway width. The culvert will be embedded approximately 3.5 feet below the channel grade and backfilled with native streambed material to maintain a natural channel bottom that will provide fish passage similar to adjoining reaches of the channel

Project Benefit    

This project will remedy an existing barrier to steelhead migration on an important tributary to the Carmel River by removing an existing set of perched 48-inch road culverts in Potrero Creek and replace them with an arched culvert designed to improve fish passage conditions, improve flood conveyance and provide safe vehicle access across Potrero Creek. Immediately upstream of the project site 90% of the watershed and stream is on protected land and supports several miles of well-shaded, spring enhanced creek habitat with deep perennial pools and spawning and rearing habitat for steelhead.
