INTRODUCTION This Soil Suitability Study presents the results of our investigation concerning the soil strata and groundwater under the subject property referenced on the Title Page. Our study was completed to satisfy the requirements of the San Joaquin Environmental Health Department(EHD), specifically: 1.) To determine if the homesite Parcel (Parcel 3)that is being split-off is acceptable for the proper operation of a septic system which will function as intended for its anticipated lifespan, 2.) Test water from on-site domestic well for nitrate and the agrichemical DBCP/EDB, 3.)Address the on-site wellhead that is in need of repair, and 3.)Provide analysis and recommen- dations based upon the environmental criteria encountered in this study. Our report is in compliance with the requirements for a Soil Suitability Study under Development Title Section 9-1105.2 Item (d) of the San Joaquin County Ordinance Codes. SUBJECT SITE AND STUDY AREA BACKGROUND INFORMATION The property is located southeast of the city of Tracy, south of I I' Street and west of Chrisman Road. Surrounding property use consists predominately of agricultural production land - primarily row crops. Surrounding structures consist of newly constructed housing subdivisions, low density single family housing and residential ranchettes along Schulte Road, a Mausoleum and commercial businesses near the intersection of Schulte and MacArthur Roads. The purpose of this project is to create three new parcels from an existing 70 acre parcel. Parcel 1 is to contain 26.19 acres,parcel 2 is to contain 21.9 acres and parcel 3 is to contain 23.45 acres. Parcel 1 and parcel 3 are currently planted entirely in beans and there are no buildings on these two parcels. The acreage that is currently being farmed in Parcels 1, 2 and 3 will eventually be built-out as tract housing. City of Tracy sewer will serve these subdivisions. Parcel 2 contains two single family residences, a shop and a two car detached garage with the remaining acreage also planted in beans. A domestic well directly west of the shop serves domestic water for parcel 2. The southwest corner of Parcel 3 is to contain Randy Mattos's future residence. This single family residence is proposed to contain three bedrooms, 2.5 baths, two of which will be full baths. A new well will be drilled for this parcel. The subject property is currently zoned Agriculture-Urban Reserve (AU-20). The attached Tentative Parcel Map illustrates the designations and orientation of the subject Parcels. The topography of the site has a land declination toward the north-northwest starting at approximately 20 feet above MSL. Septic system design criteria for slopes does not have to be considered for Randy Mattos's future residence. Due to the porosity of the on-site soils, stormwater drainage from parcels 1, 2 and 3 infiltrates into the soil quickly. If sheet flow does occur,runoff goes into the surrounding cropland. The property is in flood zone 7 according to the Tentative Parcel Map. Additionally,there is an Westside Irrigation ditch which traverses parcel 2 and parcel 3, adjacent to Schulte Road.
