The project includes partial demolition of all existing facilities and equipment, a new fish screen and fish diversion screens, a new pneumatically operated crest gate and modifying the existing Bellota weir, and a new fishway. As part of this project, a geotechnical subsurface exploration program consisting of nine mud-rotary boring to the depth of 70 feet will be carried out on the north and south side of the weir. Work-plan: Nine geotechnical soil borings using mud-rotary method will be carried out to a depth of 70 feet. The bore-hole diameter will be four inches. Representative samples will be obtained at various depths to carry out geotechnical laboratory tests and characterize the sub-surface. No environmental testing will be carried out. After completion of boring, the hole will be grouted using neat cement grout (1 bag (94 lbs.) Portland Cement to 5 to 10 gallons of potable water) using tremie method and the surface will be restored back to original condition. Exploration Location: The location details (Latitude, Longitude and APNs)for each exploration location is outlined in the Table below. Exploration location map is attached along with the filled out permit applications. The boring locations are marked and labeled in the map. Please note the mud-rotary borings are denoted by HDR-B # in the table below and the exploration location map.
