Soil Borings On December 18, 2013, Live Oak excavated one shallow soil boring on Parcel 1 of the Site for the purpose of conducting a percolation test. The boring was four inches in diameter, 3.35 feet deep, and was excavated by hand auger (Table 2). The location of the boring is indicated on Plate 9. The soil in the boring was similar to that described by the Soil Survey. Very fine sand with silt was encountered in the boring to the full depth of the hole. The log for the soil boring is presented in Plate 10. Discussion of Soil Lithology Based on the soil observed in the boring, there appears to be good potential for percolation in the test location. Sandy soils generally have a much greater potential for percolation than fine-grained or cemented soils. However, a percolation test is the only accepted method for determining the suitability of the soils for a septic disposal area. Percolation test results are discussed in the following section.
