Soil conditions were found to be <br /> comparable in all four borings. Table 3 presents the soil log for the percolation test holes. <br /> Table 3. <br /> Soil Boring Log for P-1 (Shallow). <br /> Depth Interval(ft) Soil Type Unified Soil Classification <br /> 0-3.2 Brown,silty,fine to medium sand SM <br /> Typically, sandy soils exhibit rapid percolation rates. <br /> 6.0 PERCOLATION TEST INFORMATION <br /> 6.1 Percolation Test Boring Locations <br /> One shallow percolation test was performed on June 9, 2004. Per the direction of Mr. Monte <br /> Seibel, only parcel 4 of the Site was tested because construction is not allowed on parcel 3. <br /> The location of the test is indicated in Plate 1. <br /> 6 <br />
