INTRODUCTION <br /> Our office was contracted by Mr. Ryan Voorhees of CRV Enterprises Inc., to conduct a <br /> soil suitability/nitrate loading study for a proposed lot line adjustment involving six (6)parcels <br /> located along Nichols Road just north of Liberty Road, Galt, California(Plate 1). The assessors <br /> parcel numbers for the project site are APN 005-080-22, 23, 24, 25, 26, 27. <br /> The soil suitability/nitrate loading study was conducted to determine if the soils are <br /> suitable for the use of a septic system and to estimate whether the proposed project will impact <br /> ground-water quality. The study was performed according to the requirements of Section 9- <br /> 1105.2(d) of the San Joaquin County Development. Major elements of the fieldwork included <br /> six(6) soil profile borings and twelve(12) in-situ percolation tests,required by San Joaquin <br /> County Public Health Services for final approval of the lot line adjustment. <br /> In addition to conducting the field work, a review of published soil information, geologic <br /> maps, and available ground water information was reviewed to determine the suitability of soils. <br /> Due to the County's concern with nitrate contamination of shallow ground water in the area, a <br /> nitrate loading balance was an additional requirement for project approval. The nitrate loading <br /> study was conducted to estimate the potential impact of leaching nitrates from the septic system <br /> into ground water. This report presents the results of our study. <br /> H. PROPOSED DEVELOPMENT <br /> The project will consist of a lot line adjustment involving six (6) existing parcels. <br /> It is proposed to create five(5), 2-acre parcels and one(1) 110-acre parcel. The five(5) 2-acre <br /> parcels are planned to be developed into residential sites with water wells and septic systems on <br /> each lot. The large 110 acre parcel will remain open for cattle grazing. <br />
