Q 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 County Environmental Health Department (EHD). The EHD requires this information to: 1.) Document the soil characteristics under the proposed leachfield area, 2.) Test the proposed Ieachfield permeability through percolation testing, and 3.) Test the on-site domestic well, all to ensure public health and safety. Additionally, analysis and recommendations are provided 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 and 2. The subject property is located nine miles southeast of the City of Tracy. Y Surrounding land use consists predominately of open pasture, rock, sand and gravel quarries, and Highway 580. Current zoning is AG 160.which is not anticipated to change through a General Plan Amendment/Rezone. Municipal sewer will never serve this area. (§ 1.1, 1.2, 2.1 ) The purpose o his- Permit Application projec zs to build a commercial horse stable for a'maximu of 30 horses, hich wig lirb 2,1b0-.s f--Tfere is an existing 2,400 s.f., horse barn and riding aren ition y, there is an existing 1,996 s.f primary dwelling, a 499•-�` s.f second unit dwelling, and a 1,200 s.f mobile home, all served by one domestic well since the subject property is a single Parcel.' Each residential structure has an individual septic system. The applicable area of the subject prope_rt +'is depicted on a Site Plan prepared by Ms. Cheatwood, and a Google Aerial Map, found in�pendix "" . Building orientation along with the well and f septic system are also denoted on t�e...�ite'Plan. (§ 3.7) total �ur se ' systems (three existing septic systems for the residential structures and a n system toe e horse barn)will be on the subject Parcel comprising approximately 314 ; cres. This creates a septic system density which can be considered extremely low. (§ 4.2) Any of the above land use could create environmental concerns t be i overed in the future. The on-site domestic well tested high in nitrate concentrati( at 46 ppm as rate.. This.. may be attributed to three potential sources: 1.) The horses that have been _ -site, 2.) Agricultural production that occurred several years ago which was mainly grain production, or 3.) Natural formation of nitrate from both atmospheric and geological sources over eons.
