(§(,2; 3 and On April 20, 2016, 0800 Ins, a shallow perc test boring of 42 inches was hand-drilled in the locations illustrated on the attached Tentative Map, approximately 100 ft north of Linne Road. This distance will allow any future residence convenient utility access from Linne Road. 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 a three-inch perforated PVC pipe was inserted into both test borings. The borings were then pre-saturated with 18 inches of clear water. (§6 On April 21,2016, 0700 hrs,percolation testing commenced. There was no standing water er the 24-hour soak period in the perc test borings due to the silty-sandy type soil, as illustrated in Table 1 below. Consequently, EHD Perc Test Procedure#2 was conducted for the three test borings. The last half hour of the test was witnessed by Frank Girardi, R.E.H.S. of the San Joaquin County Environmental Health Department. The maximum acceptable perc rate is 60 min/in for shallow depth perc lest borings. Therefore, the perc tests passed by an approximate factor of 8. i 1.4 and 6.8) The following Table illustrates the proposed Parcel number, septic system cture 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.

The map shows the groundwater depth under the subject property area to be approximately 50+ ft below grade. The 2015 Lines of Equal Elevation Map illustrates the groundwater directional flow in a northeasterly direction toward the San Joaquin River. The property is in Flood Zone C and not subject to 100-year flooding. Page -3-
