(§ 1.0) INTRODUCTION F76�aractenistics bility Study presents the results of my investigation concerning the soil nd groundwater under the subject property referenced on the Title Page. It was patisfy the requirements of theSan Joaquin Environmental Health Department (EHD), specifically: 1.) To determine if the proposed two Parcels to be created from this subdivision are acceptable for the proper operation of a 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. This 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 are referenced at the beginning of an applicable sentence,paragraph or paragraphs, or Appendices that correspond with the EHD Requirements Checklist for a Soil Suitability Study. (§ 2.0) SUBJECT SITE AND STUDY AREA BACKGROUND INFORMATION (§ 1.1, 1.2, 2.1 ) The purpose of this project is to subdivide an existing 114.51± acre Parcel into two Parcels denoted as Parcel 1, which is to be 5.00 acres, and a Designated Remainder, which is to be 109.51 acres. This Parcel area is depicted on the S.J.C. Parcel Viewer Map found in Appendix A. Mr. Olson's single family residential (SFR) structure exists near the middle of the southern edge of proposed Parcel 1. A septic system and domestic well serve Mr. Olson's residence. The septic system leachfield for his house is at the south end, and the domestic well is directly east of the house. The Designated Remainder presently contains a vineyard and an irrigation well. There is no proposal to build a new home on the Designated Remainder, or a second unit dwelling on Parcel 1. '-(§ 3.7) Each Parcel orientation is denoted on the attached Tentative Map, also found in Appendix A. It is possible EHD would support a second unit dwelling on proposed Parcel 1. If the primary house and a second unit dwelling were built on Parcel 1, and a primary and second unit dwelling built on the Designated Remainder, this would give a total of four septic systems on the two Parcels comprising approximately 115 acres. This is a density of one septic system per 29 acres, which can be considered very low. (§ 1.1 and 2.1) The subject property is three miles directly north of the town of Clements. Surrounding property use consists predominately of very low density single family homes, ranchettes, vineyards, confined animal facilities primarily horse ranches, and other types of ag buildings. Current zoning is AG 40. No proposal exists to change the zoning. Municipal water and sewer will probably never serve this area. Lof the above land uses could create environmental concerns that may be discovered in As evidenced by the testing of the on-site domestic well and ag irrigation well, nitrate concentrations are very low, presumably due to the deep groundwater depth in This will be discussed in Section 4 of this report.
