Coastal Watershed Restoration Program: Geomorphic Restoration Project

The Coastal Watershed Restoration - Geomorphic Restoration Project Environmental Assessment examines alternative means to restore natural hydrologic function at these locations and assesses the potential environmental effects of the implementation of each strategy. This Environmental Assessment addresses two water impoundments and one road crossing site within the Drakes Estero Watershed. Project areas include the Glenbrook Road Crossing, a non-conforming structure in the Philip Burton Wilderness, Muddy Hollow Dam and Limantour Beach Pond Dam, both constructed across portions of Estero de Limantour. The project is intended to restore natural conditions and increase estuarine habitat at Point Reyes. The project is needed to reduce the maintenance demands at Point Reyes, to eliminate the risk of catastrophic failure of culverts and dams, and to increase sustainability, both operationally and ecologically within these small coastal watersheds. This Environmental Assessment evaluates the potential environmental consequences of three alternative strategies for implementing the Coastal Watershed Restoration – Geomorphic Restoration Project.
