Hinkle Reservoir Embankment Restoration and Repair Project

The Hinkle Reservoir Embankment Restoration and Repair Project, managed by the San Juan Water District, involves the rehabilitation of the west and northwest embankment face and the toe drainage swale of a potable water storage facility located in Granite Bay, California. The primary objective of the work is to extend the infrastructure's lifespan, enhance resistance to erosion, and lower future maintenance costs for the benefit of the District's rate payers. Key technical requirements include repairing rivulets caused by water run-off and installing an armored layer of crushed rock to prevent future erosion. Additionally, the existing rock swale, which has become filled with silt, will be replaced with a concrete swale to ensure easier cleaning and maintenance. The project is classified under NAICS code 237990 and is designated as a forecast with a posted date of July 24, 2026. According to the Notice of Exemption dated July 22, 2026, the project is exempt from environmental review under the California Public Resources Code as it involves no expansion and is not expected to cause significant environmental impact. Mark Hargrove, Senior Engineer, serves as the primary point of contact for the project. The work will be performed at the Hinkle Reservoir located at 9935 Auburn Folsom Road, Granite Bay, CA 95746.
