QUASHNICK ROAD,STOCKTON, CALIFORNIA <br /> 'r OUR JOB NUMBER: LG02-310 <br /> I. INTRODUCTION <br /> Our office was contracted by Mr. Robert Jones to conduct a Soil Suitability Study for a <br /> 3.36 acre parcel located at 5533 E. Quashnick Road in Stockton, California(Plate 1). The <br /> assessors parcel number for the subject parcel is (APN) 086-070-49. The San Joaquin County <br /> project number for the project is MS-00-11. The Soil Suitability Study was required by the San <br /> Joaquin County Environmental Health Division as a condition for project approval. A site plan <br /> of the property was provided to our office by the client. The site plan was prepared by Earnest F. <br /> Smith, Civil Engineer, Stockton. <br /> The Soil Suitability Study was conducted to determine whether the proposed new parcels <br /> are suitable for the use with standard septic systems. The study was performed according to the <br /> requirements of Section 9-1105.2(d) of the San Joaquin County Development. <br /> In a letter dated June 16, 2000 from San Joaquin County Public Health Services <br /> Environmental Health Division to San Joaquin County Community Development Department <br /> regarding MS-00-11, we understand that an onsite water well is to be abandoned and a soil <br /> suitability study are conditions for project approval. The water well is to be tested for nitrate and <br /> DBCP. Other requirements are mentioned in the letter. <br /> L Major elements of the Soil Suitability Study included drilling an exploratory soil boring <br /> and performing a shallow and deep percolation test for each parcel. An examination of the <br /> published soil information, geologic maps, and available ground water information, exploratory <br /> borings, percolation rates, and permit review was performed to determine suitability of the soils <br /> for use with a septic system and its potential impact to ground water. A ground water nitrate and <br /> �- DBCP test was performed. <br />
