Soil Suitability / Nitrate Loading Study <br />Cherokee Memorial Park Vineyard Chapel Addition Ŷ Lodi, California <br />March 5, 2021 Ŷ Terracon Project No. NA207102 <br />Responsive Ŷ Resourceful Ŷ Reliable 13 <br />1.5 Soil Profile and Geologic Information <br />The site is depicted on the Geologic Map of California 2010, as within generalized quaternary <br />Pleistocene and Holocene deposits which are comprised primarily of unconsolidated and semi- <br />consolidated alluvium, lake, playa, and terrace deposits. <br />Terracon reviewed the United States Department of Agriculture (USDA) Natural Resources <br />Conversation Service (NRCS)Web Soil Survey and USDA Soil Survey of San Joaquin County <br />(1992) for information regarding soil properties. Based on information obtained from the USDA <br />sources, site soils consist of Tokay-urban land complex and Tokay fine sandy loam. Tokay-urban <br />land complex consists of well drained soils with 0 to 2 percent slopes. Parent material consists of <br />alluvium derived from granitic rock sources. Typical soil profiles consist of 0 to 60 inches fine <br />sandy loam. Tokay fine sandy loam consists of well drained soils with 0 to 2 percent slopes. <br />Parent material consists of alluvium derived from granitic rock sources. Typical soil profiles <br />consist of 0 to 45 inches fine sandy loam and 45 to 60 inches sandy loam. <br />1.5.1 Soil Boring Locations <br />Soil boring information and percolation test results from the prior 2015 SSS (Section 1.1), was <br />utilized for this report. The proposed leach field for the Vineyard Chapel addition is located east <br />of the existing building and south of the existing leachfield (Exhibit 2). In 2014, two percolation <br />test borings P1 and P2 were advanced in the vicinity of the proposed leach fields. <br />1.5.2 Soil Boring Dimensions <br />No additional borings were provided; however, in 2014 two soil borings (P1 and P2) were <br />advanced with a 4-inch diameter hand auger to 3.05 and 3.07 feet bgs. <br />1.5.3 Soil Lithology Observed <br />The table below is based on the prior soil suitability report from July of 2015 (Section 1.1). <br />Table 7. <br />Summary of Soil Lithology <br />Boring Depth Interval (ft)Soil Type Unified Soil <br />Classification <br />P1 0-3.05 Silty Sand SM <br />P2 0-3.07 Silty Sand SM
