(§ 6.2, 6.3 and 6.5) On December 2, 2005, 1400 hrs, one shallow perc test boring at 42 inches and one deeper test boring at 15 feet were drilled with a truck-mounted drill rig on proposed Parcel I and Parcel 2, along with the 25 feet exploratory boring. The test borings for Parcel 1 was drilled ' in an anticipated homesite location. The sidewalls of the shallow borings were scored with a pry-bar and the loose material removed. V, The deeper borings could not be scored due to their depths, nor was there a need to score the sidewalls since there is a sandy soil structure at this test depth. Two inches of fine gravel was placed at the bottom and three-inch perforated PVC pipe was inserted in each of the four test borings. All borings were pre-saturated on December 8, 2005 at 1000 hrs with 12 inches of water. (§ 6.4) On December 9, 2005, 0900 hrs,percolation testing commenced for all four borings. There was standing water after the 24-hour soak period in the two shallow perc tests borings due to the clay/hardpan type soil, as illustrated in Table 1 below. Consequently, EHD Pere Test Procedure#1 was conducted for these two borings. There was no standing water after the 24-hour soak period in the two deep test borings. Therefore, EHD Test Procedure#2 was performed for these borings. 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 deep tests.
