§1.0 INTRODUCTION AND PROPOSED DEVELOPMENT cr , I This Soil Suitability Study presents the results of my investigation concerning the soil characteristics and groundwater under the subject property referenced on the Title Page. This study was completed to satisfy the requirements of the San Joaquin County Environmental Health Department (EHD), specifically: 1.) To determine if the two Parcels proposed to be subdivided are acceptable for the proper operation of any future septic system, which will function as intended for its anticipated lifespan, and 2.)Provide analysis and recommendations 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. Within the text of this Report,bolded Section (§)numbers will be referenced at the beginning of an applicable sentence, paragraph or Appendix that correspond with the EHD Requirements Checklist for Soil Suitability Studies. §1.1 and §1.2. The purpose of this project is to create two new parcels from a total original Parcel area of 18.02 acres. Zoning is AL-10. Presently,there are two residential structures on the property, each with a domestic well and septic system. Mr. Darwin Inman lives in the house on proposed Parcel 1 and Mr. and Mrs. Roy Silva live in the house on proposed Parcel 2. Proposed Parcel 1 also contains a detached garage, enclosed barn and a hay barn. Each parcel area and orientations are denoted on the attached Tentative Map, found in Appendix A. Sections §1.3 and §1.4 are found in the Appendices. The reason for this subdivision is exclusively for family purposes. There is no proposal to build a second unit dwelling on either Parcel at this time. §3.7. However, it is possible EHD would support second unit dwellings on the proposed Parcels for a total of four septic systems on the subject property acreage of 18 acres. I §2.0 PRESENT AND PAST USES OF THE SITE §2.1. The subject property has been owned by the Silva and Inman Families since the 1930's when Darwin Inman's deceased grandfather, Mr. Tony Silva,purchased the property. The property has been, and currently is, used for beef cattle grazing and shelter. Pasture land is flood irrigated. Surrounding property use consists predominately of very low density single family residences, ag buildings, farmland, orchards, ranchettes, and dairies. Any of these land uses could create environmental concerns that may be discovered in the future. §4.2. Of primary concern,would be nitrate contamination of the underlying groundwater, especially from surrounding agricultural activities. As depicted on the attached USGS Map and the Tentative Map, the topography of the site is 132 feet above MSL, with a very slight land declination toward the southwest. Therefore, septic system design criteria for slopes do not have to be considered. Page -1- Chesney Consulting
