We will perform a total of 5 soil borings on the proposed site. Four of the borings will be drilled to a depth of feet below existing grades and one of the borings will be drilled to a depth of feet below existing grades. The borings will be located within the bounds of the private property. The borings will be drilled utilizing 4. 25 hollow stem, continuous flight augers and/or mud rotary drilling. The borings will be performed utilizing a truck-mounted drill rig and will generate an approximate 6 inch annulus. After geotechnical exploration is completed, the borings/auger probes will be backfilled with bentonite slurry, which has a consistency of two pounds of bentonite powder to one gallon of water. Borehole/auger probe abandonment will be performed by tremie-grouting via a positive displacement pump from the bottom of the borehole/auger probe.
