Document Description
To assist with the design and construction of Pacheco Reservoir Expansion Project, up to 149 subsurface exploratory borings (to include 119 initial borings and 30 supplemental borings) are proposed to obtain essential information on subsurface geologic and geotechnical conditions. In addition, a total of 32 test pits are proposed as part of the Project to explore a potential borrow area for dam core zone material for the design and construction of the Pacheco Reservoir Expansion Project. The Project also proposes two types of linear surface geotechnical investigations within the Project study area to include seismic refraction and electrical resistivity. One electrical resistivity survey would be performed across the valley bottom within the upstream portion of the proposed dam. In addition, nineteen seismic-refraction lines totaling approximately 16,890 linear feet are proposed at multiple locations.
