(§ 5.2, 5.3, and 5.4) A Log of Boring using the Unified Soil Classification System (U.S.C.S.), as observed in the perc test boring, is found on the EHD PERCOLATION TEST DATA SHEET. Generally,the underlying surface soils show a consistent very fine sandy silt/ clay soil with a high degree of stickiness. No cemented silts hardpan soil stratum was discernible. (§ 6.1) Percolation testing was conducted at the location illustrated on the Tentative Map found in Appendix C. This test location maintains sufficient distance requirements between wells, property lines, irrigation lines and ditches, etc. The following information describes the y preparation of the percolation test borings and the actual percolation testing: (§ 6.2, 6.3 and 6.5) On December 5, 2011, 0900 hrs, a shallow perc test boring of 42 inches was hand-drilled 100 ft to the southwest of the metal building. The sidewalls of the shallow boring were scored with a pry-bar and the loose material removed. Two inches of fine gravel was placed at the bottom and a three-inch perforated PVC pipe was inserted into the test boring. The boring was then pre-saturated with 18 inches of clear water. (§ 6.4) On December 6, 2011, 0930 hrs,percolation testing commenced. There was no standing water after the 24-hour soak period in the perc test boring due to the sandy-silty soil type, as 'f illustrated in Table 2 below. Consequently, EHD Perc Test Procedure 42 was conducted for the test boring. The last half hour of the test was witnessed by Ted Tasiopoulos, R.E.H.S. of the San Joaquin County Environmental Health Department. The maximum acceptable perc rate is 60 min/in for shallow perc tests and 30 min/in for the medium depth perc test borings. (§ 5.4 and 6.8) The following Table illustrates the proposed Parcel number, septic system structure to be installed based on the depth of the passing perc rate, proposed acreage, post soak period status and perc test results for the respective perc test.
