This project will remove sediment along 3,500 feet of Arroyo Mocho, from confluence with Arroyo de la Laguna to Hopyard Road to increase hydraulic capacity. Build a new floodwall along Arroyo Mocho south of the maintenance road to protect Valley Trails from flooding. Construct localized bio-technical bank slope stabilization measures and utilize grade control structures. Conduct habitat enhancement through replacement of existing drop structures with fish passable structures, creating a low-flow channel, and planting of shaded riverine aquatic cover.
Remove sediment to curtail aggradation of Arroyo Mocho at confluence with Arroyo de la Laguna. Enhance in-stream aquatic habitat for steelhead.
