r <br /> K <br /> This test location maintains sufficient distance requirements between wells,property lines, etc. <br /> The following information describes the preparation of the percolation test borings and the actual <br /> percolation testing: <br /> (§ 6.2, 6.3 and 6.5) On March 27, 2006, 1245 hrs, one shallow perc test boring of 42 inches was <br /> drilled with a truck-mounted drill rig on proposed Parcel 1 and Parcel 2. The test boring for Parcel <br /> 2 was drilled 100 feet to the west of the building pad, although there is no proposal to build on this <br /> Parcel at this time. <br /> The sidewalls of the shallow borings were scored with a pry-bar and the loose material removed. <br /> Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted <br /> in each of the two test borings. All borings were pre-saturated on March 28, 2006 at 1000 hrs with <br /> 12 inches of water. <br /> (§ 6.4) On March 29, 2006, 0900 hrs, percolation testing commenced for both shallow test borings. <br /> There was no standing water after the 24-hour soak period in the perc tests borings due to the sandy <br /> type soil, as illustrated in Table 1 below. Consequently, EHD Perc Test Procedure#2 was conducted <br /> for both test borings. <br /> 1 The last half hour of the tests was witnessed by Michael Escotto, R.E.H.S. of the San Joaquin County <br /> Environmental Health Department. The maximum acceptable perc rate is 60 min/in for shallow perc <br /> tests. <br /> (§ 5.4 and 6.$) The following Table illustrates the proposed Parcel number, septic system structure <br /> to be installed based on the depth of the passing perc rate and the comparatively shallow depth to <br /> groundwater, proposed acreage,post soak period status and perc test results for the respective perc <br /> test: <br /> TABLE 1 <br /> NNI <br /> PERCOLAT�ON,TEST,RESULTS`AND,RELATED DATA`, <br /> PROPOSED PARCEL PROPOSED SHALLOW PERC TEST POST SOAK PERC TEST <br /> POTENTIAL SEPTIC ACREAGE DEPTH PERIOD RESULTS <br /> SYSTEM STRUCTURE STATUS <br /> EXISTING WELLS <br /> Parcel 1 3.57 t Acres 42 INCHES No Standing 14.7 min/in <br /> Leachlines Water in Hole <br /> Existing House Pad <br /> Parcel 2 38.30 t Acres 42 INCHES No Standing 15.6 min/in <br /> Leachlines Water in Hole <br /> Two Irrigation Wells <br /> One Domestic Well SFR <br /> with Septic System <br /> Page -3- <br /> Chesney Consulting <br />
