Document Description
DWR staff will remove soil mounds from the inner slope of Clifton Court Forebay (CCFB). There are approximately 77 mounds totalling 390 cubic yards. The soil will be removed using an excavator and loaded into a dump truck for transport to the onsite spoil pile located south-east corner of the forebay. Any riprap will be blended close to the toe of the embankment above the water line. Dust control will be via water truck. It is anticipated that none of the excavated material will enter the water. Staging will occur along the paved roadway along the crown of CCFB dam. All work is within DWR right-of-way.
