1�� 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 250 acre parcel into two equal 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 250.0± acre Parcel, into two Parcels denoted as Parcel 1, which is to be the east-half of the property at 127.0 acres and Parcel 2, which is to be the west-half at 123.0 acres. Currently, there are a residential structure and a metal shed in the southwest corner of proposed Parcel 1. The residential structure was previously a farm labor camp. It is currently being rented out by Mr. and Mrs. Rodriguez. A domestic well serves both structures, and a septic system serves the residential structure. The entire Parcel (save the referenced structures) is planted in rotational crops such as corn, oats, etc. There is no irrigation well on the property. The Woodbridge Irrigation District (WID) 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 it is proposed to be outside of a 100-foot radius from where the perc tests were done for this Study. If a primary house and second unit dwelling were built on Parcel 1, and with a primary and secondary house on Parcel 2, this would give a total of four septic systems on the two Parcels consisting of approximately 250 acres. This is a density of one septic system per 62.5 acres, which can be considered extremely low density. Nitrogen fertilization and mineralization from organic matter decomposition within the cropland areas would constitute a much greater nitrogen input than from four septic systems. (§ 1.1 and 2.1) The subject property is approximately nine miles west of the city of Lodi. Surrounding property use consists predominately of agricultural production land such as row crops and vineyard, a helicopter crop-dusting company, extremely low density single family homes, ranchettes, and ag buildings. Current zoning is AG 40, which will not change. Municipal sewer will never serve this area. P. O. Box 3794 • 7urCock CA 9538dgE -office (209) 668-1403 • Fax (2o9) 668-2598
