Document Description
The Patterson Reservoir Remediation Project will restore storage capacity and maximize the operating water level while providing sufficient freeboard for the Reservoir as required by the California Department of Water Resources, Division of Safety of Dams (DSOD). The project involves constructing earthen berms on the east and west side of the existing Reservoir, tying into high ground on the north and south sides to create a ring around the Reservoir. To facilitate construction activities, existing utilities would be protected-in-place, relocated, or removed from service. Project construction is anticipated to take approximately 6 months between Spring 2027 and Fall 2027. The Project site is located at Patterson Reservoir along Patterson Road, off Paseo Padre Parkway in the City of Fremont, between Coyote Hills Regional Park and Dumbarton Quarry Campground, north of Highway 84, California.
