Document Description
The proposed project involves improving the Chabot Dam embankment and foundation through cement deep soil mixing (CDSM). The outlet works would be improved by strengthening the outlet pipe and an existing vertical shaft located behind the tower, installing new valves and controls in the vertical shaft, and removing the outlet tower and pavilion. Excavated materials would be stockpiled at the Filter Pond Stockpile and/or Park Stockpile, which are located at the former water treatment 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. The entire project site, including haul routes and stockpile areas, is located within EBMUD property.
