Whale Rock Reservoir Spillway/Open Space
Document Description
The proposed project includes dewatering, sediment removal, and visual inspection of the spillway basin below Whale Rock Reservoir. The City of San Luis Obispo is required by the Division of Safety of Dams to inspect the integrity of the spillway basin below Whale Rock Reservoir. In order to conduct the visual inspection, the City must first dewater the lower section of the basin, then remove accumulated sediments and vegetation from the area for an engineer to gain and see the basin bottom. The project would result in approximately 0.10-acre and 160 linear feet of temporary impacts to waters of the state, including 0.10-acre and 160 linear feet of temporary impacts to waters for the U.S. Specifically, temporary impacts are expected as a result of dewatering and excavating accumulated sediment and vegetation. No permanent impacts are proposed.
