Document Description
The proposed project involves improving the Chabot Dam embankment toe through conventional earthwork or cement deep soil mixing (CDSM). The outlet works would be improved by re-lining the vertical brick-lined shaft that connects the sluice gate control to the outlet pipes, moving the valves and controls from the existing tower to the vertical shaft, relining or installing new outlet pipes from the vertical shaft to the reservoir, filling the tower with low strength flowable fill, retrofitting the tower walls, and removing the pavilion. Excavated materials would be stockpiled at the Filter Pond Stockpile and/or Park Stockpile, which are located at the former filter ponds and Chabot Park, respectively. Two potential haul routes are proposed within the project site: Upper Haul Route and the Lower Haul Route. Following the Chabot Dam seismic upgrade activities, the footprint of the project area would be returned to existing conditions.
