(§ 5.2,5.3, and 5.4) A Log of Boring using the Unified Soil Classification System (USCS), as observed in the deep perc test borings completed on each Parcel, is found on the EHD PERCOLATION TEST DATA SHEET. Generally, the underlying soils show high clay content soils at typical leachline depth, except for the Parcel 2 area, and thin cemented silts hardpan soil at (s.� approximately six feet and eight feet below the ground surface. The remaining soils are a silty fine sand/sandy silty clay. (§ 6.1) Percolation testing was conducted in the locations determined by the Applicant, Mr. Louis Bucher. These test locations are illustrated on the Tentative Map found in Appendix C. These locations maintain sufficient distance requirements between wells,grope Ines, a c. in accordance with EHD regulations. The proposed Designated Remainder was not perc tested per EHD requirements. The following information describes the preparation of the percolation test borings and the actual percolation testing: (§ 6.2,6.3 and 6.5) On September 25, 2007, one shallow perc test boring of 42 inches and three various depth test borings were drilled with a truck-mounted drill rig on proposed Parcels 1, 2 and 3. These deep test depths are denoted below in Table 1. The sidewalls of the shallow borings were scored with a pry-bar and the loose material removed. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted (� 3 in each test boring. All borings were pre-saturated on October 7, 2007 at 1000 hrs with 12 inches of water. (§ 6.4) On October 8, 2007, 0903 hrs,percolation testing commenced for all six test borings. There was standing water after the 24-hour soak period in the Parcel 1 and 3 shallow perc test borings; therefore, EHD Perc Test Procedure#1 was conducted. For the remaining test borings, EHD Perc (�•S� Test Procedure#2 was performed. The last half hour of the tests 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 deeper perc tests. (§ 5.4 and 6.8) The following Table illustrates the proposed Parcel number, septic system structure to be installed, proposed acreage, post soak period status and perc test results for the respective perc test: Page -3- Chesney Consulting
