0 1.0) INTRODUCTION 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. It was completed to satisfy the requirements of the San Joaquin Environmental Health Department (EHD), specifically: 1.) To subdivide an existing 10-acre parcel into two Parcels and to determine if the underlying soil of these proposed Parcels are acceptable for the proper operation of any future septic system that may be installed which will function as intended for its anticipated lifespan, and 2.) Provide analysis and recommendations based upon the environmental criteria encountered in this study. Currently, there is no proposal to construct any buildings (residential or otherwise) on the subject property. 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 10± acre Parcel, into two Parcels denoted as Parcel 1, which is to be the west-half of the property at a net acreage of 4.77 acres and Parcel 2, which is to be the east-half of the property at 4.414 acres. Currently, there are a residential structure, barn and garage in the northeast corner of proposed Parcel 2. The residential structure is Mrs. Palesch's house. A domestic well and a septic system serves the residential structure. The entire Parcel (save the referenced structures) has been, and is currently planted in rotational crops such as oats, and various row crops. There is no irrigation well on the property. The Central San Joaquin Water Conservation District(CSJWCD) delivers irrigation water to the subject, and surrounding properties. (§ 3.7) Parcel orientation is denoted on the Tentative Map found in Appendix A. Any building, proposed to be built on the proposed Parcels will have to observe all EHD requirements, which would include a perc test in the location of any future building if constructed outside of a 100-foot radius from where the perc tests were conducted for this Study. If a primary house and second unit dwelling were built on Parcel 1, and with the primary and secondary house on Parcel 2, this would give a total of four septic systems on the two Parcels consisting of approximately 10 acres. This is a density of one septic system per 2.5 acres, which can be considered marginal density for nitrate loading considerations. Nitrogen fertilization and mineralization from organic matter decomposition within the cropland area would constitute a much greater nitrogen input than from four septic systems.
