(§ 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 Page7v] completed to satisfy the requirements of the San Joaquin Environmental Health Department (EHD), specifically: 1.) To determine if the four Parcels proposed to be a part of the five Pasubdivision 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 upenvironmental 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 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 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 39.7 acre Parcel, into four 5-acre Parcels and a Designated Remainder. It is proposed to construct single family residential (SFR)structures on Parcels 1, 2, 3 and 4, which are currently vacant. The Designated Remainder presently contains animal barns/buildings, goats and llamas, a retention basin, three mobile homes and one house, septic systems for these structures, and a domestic well directly northeast of the mobile homes. An agricultural well with an aboveground rotary pump is located west of the animal barns. Found directly south of this well, is a sump approximately 20 feet by 20 feet. A turbine pump is 30 feet northwest of the pressure tank associated with the aboveground rotary pump. The turbine pump is used to transfer water pumped into the referenced sump, back to the barns. This arrangement was installed before the Olcese's purchasing the ranch in 1983. It is unknown why the turbine pump was installed to"pick-up"water from the sump and transfer it back to the barns. There is no proposal to build any additional buildings on the Designated Remainder. Each parcel area and orientations are denoted on the attached Tentative Map, found in Appendix A. (§ 3.7) It is possible EHD would support second unit dwellings on proposed Parcels 1, 2, 3 and 4, for a total of eight septic systems on these four Parcels comprising 20 acres. This is a density of one septic system per 2.5 acres, which can be considered low. Taking into account septic systems for the existing house and three mobile homes, and assuming they all have separate systems since there were no records at EHD, bring the total systems to: 4+ 8 = 12 systems on 39.7 acres, or one system for every 3.3 acres.

Surrounding property use consists predominately of low density single family anchettes, pasture, a dairy and other confined animal facilities such as horse ranches, es of ag buildings. Current zoning isAL-5. Chesney Consulting
