INTRODUCTION This Soil Suitability Study presents the results of our investigation concerning the soil characteristics This 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 to provide analysis and recommendations based upon the environmental criteria encountered in this study. There is a domestic well, an irrigation well, and a septic system on proposed Parcel 1 of the subject property that serves the Van Vuren residence and a arm labor mobs e home The irrigation weds only operated when there is no water in Little John's Creek. The mobile home is slated to be removed, with no replacement anticipated. The domestic well, which serves both the Van Vuren residence and the mobile home was tested for the constituents stipulated by EHD, namely nitrate and the agrichemicals DBCP/EDB. 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 subject property is located at the end of Stow Avenue,which one mile from the intersection of Gawne Road and Mariposa Road. Surrounding property use consists of low density rural residential structures,pasture land, almond orchards a dairy, vineyards, and a winery. The property is currently, and will remain zoned Agriculture(ACO). The purpose of this project is only to create two new Parcels from a total area of 57.00 acres. There is no proposal to build on either of the two proposed Parcels at this point in time. Parcel 1 is to be the individual homesite parcel that contains the Van Vuren's residence. There is no proposal to build a second unit dwelling on this Parcel. Parcel 1 is to be 3.1 acres and Parcel 2 is to be 53.9 acres. Parcel 2 is to remain as irrigated pasture land for the dairy to the west that was once owned by the Van Vuren's. The Tentative Parcel Map found in Appendix "A" illustrates the designations and orientation of the subject Parcels, the location of the subject property, and the location of the percolation testing on both Parcels. Proposed Parcel 2, and a portion of Parcel 1, are currently open pasture land. As noted on the Tentative Map,this pasture land is flood irrigated with the water supplied and managed by the Central San Joaquin Water Conservation District. Municipal sewer will probably never serve this area, or at least not for several decades. As depicted on the attached USGS Map, the topography of the site is 74 feet above MSL, with a slight land declination toward the southwest to 70 feet MSL for efficient flood irrigation. Therefore, septic system design criteria for slopes do not have to be considered. A review of Application Permits on file with the Environmental Health Department reveals there has been one licatio4 for Repairs/Additions to septic systems in the surrounding one-half mile study area. This can be considered a low number of Repairs/Additions and can be attributed to the very low density housing surrounding the property and the fact that seepage pits have most likely been installed for all of these residential units.
