Soil Suitability/Nitrate Loading Study Irerracon <br /> Gribaudo Property ■Acampo, CA <br /> November 12, 2019 ■ Terracon Project No. NA197081 <br /> Table 3. <br /> USDA Soil Types. <br /> Map Symbol Name Percent of Site Location <br /> 101 Acampo sandy loam 92.5 Across majority of the site <br /> 111 Bruella sandy loam 0.30 Northwest corner of APN 017-260-31 <br /> 157 Exeter sandy loam 7.2 Along northeastern boundary of APN <br /> 017-260-30 <br /> Based on the USDA soil map, the percolation test boring locations are located within Acampo <br /> sandy loam soils. According to the USDA Soil Survey of San Joaquin County (1992), Acampo <br /> sandy loam soils consist of moderately well drained soils with 0 to 2 percent slopes. Typical soil <br /> profiles consist of 0 to 47 inches sandy loam and 47 to 60 inches cemented soils. The main <br /> limititations for this soil type include depth to hardpan. For homesites with septic systems, ripping <br /> the hardpan may improve permeability. <br /> 1.5.1 Soil Boring Locations <br /> The soil boring locations were selected by Mr. Vlach. The percolation test boring (B1) and soil <br /> profile boring (B2) were placed near the existing leachfield south of the residence APN 017-260- <br /> 31. Percolation test boring B3 and soil profile boring B4 were placed near the northwestern <br /> portion of APN 017-260-30. <br /> Table 4. <br /> Soil Boring Locations. <br /> Boring Depth Latitude Longitude Location APN <br /> No. Feet <br /> 61 3.25 38.189445 -121.188945 18 feet south of residence,43 feet 017-260-31 <br /> Percolation Test Boring east of Sowles Rd <br /> B2 9.0 38.189439 -121.188897 10 feet east of 61 017-260-31 <br /> Soil Profile <br /> B3 3.25 38.189548 -121.186870 80 feet south of Peltier Road 017-260-30 <br /> Percolation Test Boring <br /> B4 5.5 38.189503 -121.186859 90 feet south of Peltier Road south 017-260-30 <br /> Soil Profile I of B3 <br /> Refer to Appendix A, Exhibit 2 for the boring locations. <br /> 1.5.2 Soil Boring Dimensions <br /> Soil borings B1 through B4 were advanced with a 4 inch diameter handauger. Refer to Section <br /> 1.5.1 for boring depths. Soil profile borings B2 and B4 were advanced until refusal. <br /> 1.5.3 Soil Lithology Observed <br /> The following table presents a log of the soil boring(s). <br /> Responsive■ Resourceful ■ Reliable 9 <br />
