feet below ground surface, followed by sandy clay to 6 feet, silt/sand mixtures to 18 feet, and fine sand with silt to the full depth of the hole. The soil log for Parcel 1 is presented on Plate 12. In the borings advanced by Mr. Smith, clay was encountered to 8 feet, followed by silty sand to the full depth of the hole. Discussion of Soil Lithology Based on the soil observed in the boring, there appears to be limited potential for percolation in the shallow soil zone, but good potential in the deep soil zone. 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. Percolation Test Shallow and deep percolation tests were conducted on both proposed parcels of the Site. The soil borings discussed above were used for the percolation test holes. Live Oak's percolation test procedures conformed to San Joaquin County Environmental Health Department policy; it is presumed that Mr. Smith's did as well. Preparation and Presaturation of Percolation Test Holes After Live Oak's borings were advanced by hand auger and the soil logged, the test holes were completed for the percolation testing. Approximately two inches of pea gravel were placed in the bottom of each open soil boring, followed by a 2.0 -inch diameter PVC pipe with perforations on the bottom. Pea gravel was then used to backfill a few inches of the annular space. Live Oak presaturated the Parcel 1 percolation test holes approximately 24 hours prior to the percolation testing. Each hole was filled with water to a height of 12 inches above the bottom of the boring for the presaturation. On the day of testing, both holes were found to be intact and dry. Mr. Smith appears to have presaturated the Parcel 2 test holes as well; standing water was observed in the shallow boring on the morning of the test. Percolation Test Procedure Live Oak conducted the percolation test for the Parcel 1 borings on October 22, 2021. Due to initial percolation rates observed, a four-hour test was selected for the shallow boring, while a one-hour test was selected for the deep boring. Water level measurements were taken every 30 minutes during the four-hour period and every 10 minutes during the one-hour period. The last 30 minutes of the test were observed by LOGE 2150 Page 6
