7Thesidewalls of the shallow borings were scored with apry-bar and the loose material removed. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted in the test borings. All test borings were pre-saturated on June 21, 2005 at 0800 hrs with 12 inches of water. §6.4. On June 22, 2005, 0800 hrs,percolation testing commenced for all four perc test borings. There was standing water after the 24-hour soak period in the two shallow perc tests borings, as illustrated in Table 1 below. Consequently, EHD Perc Test Procedure#1 was conducted for these two borings. No standing water was measured after the 24-hour soak period in the remaining two deep test borings. Therefore, Percolation EHD Test Procedure#2 was performed for the deep borings. The last half hour of the tests was witnessed by David Van Dyne of the San Joaquin County Environmental Health Department. §5.4 and §6.8. The following Table illustrates the proposed Parcel number, potential septic system structure based on depth of passing perc rates, proposed acreage, post soak period status and perc test results for the respective perc test depths: TABLE 1 PERCOLATION TEST RESULTS AND RELATED DATA PROPOSED PARCEL PROPOSED PERC TEST DEPTHS: POST SOAK PERC TEST AND POTENTIAL ACREAGE SHALLOW PERIOD RESULTS SEPTIC SYSTEM STRUCTURE DEEP STATUS Parcel 1 9.01 Acres 42 INCHES 4Inches FAILED Existing Leachlines Standing Water (0 min/in) and Seepage Pits With Existing Well 141 INCHES(11.75 FEET) No Standing 4.5 min/in Water in Hole Parcel 9.01 Acres 42 INCHES --4 Inches FAILED Existing Leachlines Standing Water (250 min/in) and Sumps With Existing Well 216 INCHES(18 FEET) No Standing 5.2 min/in Water in Hole §4.0 LOCAL GROUNDWATER AND SURFACE WATER INFORMATION §4.1. The 1999 Lines of Equal Depth Map published by the San Joaquin County Flood Control illustrates the groundwater depth to be 70 feet below ground surface (b.g.s.). 1999 Lines of Equal Elevation Map illustrates the groundwater elevation and the directional flow to be in a northwest direction. The property is not subject to 100-year flooding. i Page -3- Chesney Consulting
