Subsidence and Groundwater Monitoring Project


SCH Number
Lead Agency
California Department of Water Resources (DWR)
Document Title
Subsidence and Groundwater Monitoring Project
Document Type
MND - Mitigated Negative Declaration
Document Description
The proposed Project involves the installation of groundwater and subsidence monitoring stations that would provide real-time data to monitor groundwater levels and other spatial information as they relate to ground subsidence. The data would be used to help inform how subsidence is affecting the Aqueduct and would assist in maintaining infrastructure of the State Water Project (SWP). The proposed Project involves ground disturbance such as drilling to a maximum depth of approximately 5 to 2,800 feet below ground surface (bgs), site preparation activities such as vegetation removal and grading from the embankment road to the work area, groundwater monitoring well installations and associated equipment, extensometer installations, and global positioning system (GPS) antenna and telemetry/solar panel installations. Access to the sites would be made via the Aqueduct embankment road. Some ground improvements may be required for accessibility during wet and muddy conditions such as spreading gravel over unimproved ground surfaces.
