SOIL PROFILE <br /> On 17 March 2014, an Onsite Wastewater Treatment System Permit was issued by the <br /> EHD (Appendix C) for the above referenced property. <br /> On 17 March 2014, a 4-inch hand auger was utilized to advance a percolation test hole <br /> to 42-inches bsg in the subject parcel. <br /> 5.1. SITE MAP <br /> A plan of the specific site features (i.e., structures, drives, wells, septic systems, large <br /> trees, pastures, pools, natural drainage courses, ponds, waterways, etc.) is illustrated <br /> on Figure 2. <br /> 5.2. SOIL PROFILE PIT INCLUDING DEPTH AND DIMENSIONS <br /> The test hole was located in vicinity of the north septic system, which will be utilized for <br /> the proposed winery. The percolation test hole (TH-1) was advanced to a depth of 42- <br /> inches bsg. A site plan depicting proposed site features and location of test holes is <br /> included as Figure 2. <br /> 5.3. SOIL LITHOLOGY WITHIN TEST HOLE <br /> The soil was visually described in accordance with the Unified Soil Classification <br /> System by a representative of AGE under the supervision of a California Professional <br /> Geologist. <br /> 5.4. SOIL LITHOLOGY AS RELATED TO FUTURE ONSITE SEPTIC USES <br /> The soil sample collected from TH-1 consisted of soils ranging from silty sand in the <br /> upper 40 inches to silt with clay at the base of the soil section. The soil type was <br /> considered permeable and with a quantity of coarse grained soil (sand) sufficient for <br /> liquid waste disposal and treatment. <br /> 6.0. PERCOLATION TEST INFORMATION <br /> A percolation soil suitability test was performed on the site under EHD permit No. <br /> SR0069247 on one four-inch diameter soil boring established to a depth of three and <br /> one-half feet bsg. <br /> Advanced GcoEn%ironmental,Inc. <br />
