Lower Glenbrook Dam

The Restoration of the Lower Glenbrook Quarry and Dam Removal at Turney Point Environmental Assessment (1,155 KB PDF) examines alternative means to restore natural hydrologic function and assesses the potential environmental effects of the implementation of each strategy. This Environmental Assessment addresses removal of the remnant portions of the Lower Glenbrook Dam, which breached in 1982, and restoration of the adjacent spillway and quarry areas used to construct the original dam. The remains of the dam and disturbed lands associated with the quarry and spillway are considered a non-conforming structure in the Philip Burton Wilderness. The project is intended to restore natural conditions and enhance estuarine habitat in this portion of Drakes Estero. The project would not result in habitat conversion and is consistent with other restoration efforts in the park such as the Coastal Watershed Restoration and Giacomini Wetland Restoration. This Environmental Assessment evaluates the potential environmental consequences of three alternative strategies for implementing the Lower Glenbrook Quarry and Dam Removal at Turney Point Project.
