(§ 1.0) INTRODUCTION CThis 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 create a proposed homesite Parcel 2 from this subdivision and to determine if the underlying soil of these proposed Parcels 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 (§ 1.1,111.2,'2.1) The purpose of this project is to subdivide an existinC447.5± cre Parcel (Area determination according to Tentative Map; District Viewer Map says 50.12 acres , intof t-:o`Varcels denoted as Parcel 1, which is to be 44.8 acres and the homesite Parcel, which is to be.2 h.acres. Mr. Boersma's single family residential (SFR) structure is existing on proposed Parcel 2. A domestic well and septic system serve this structure. A new well was recently drilled to replace the original well that was drilled when the residential structure was constructed. This will be discussed in Section 4 of this Report. The entire Parcel (save the residential structure) is planted in almonds. There is an irrigation well near the south-center of the property. The old domestic well and the newly drilled domestic well was sampled for this study. The irrigation well was not sampled since there is no electricity to this well. (§ 3.7) Parcel orientation is denoted on the Tentative Map found in Appendix A,produced by the engineering firm of Wong Engineers, Inc. Any building proposed to be built on proposed Parcel 1 will have to observe all EHD requirements, which would include a perc test in the location of a proposed building. If a primary house and second unit dwelling were built on Parcel 1, and with the primary (existing home) on Parcel 2, this would give a total of three septic systems on the two Parcels consisting of approximately 47.5 acres. This is a density of one septic system per 15.8 acres, which can be considered extremely low. Nitrogen fertilization and mineralization from organic matter decomposition would constitute a much greater nitrogen input than from three septic systems. (§ 1.1 and 2.1) The subject property is approximately two miles north of the town of Ripon. Surrounding property use consists predominately of agricultural production land, a manufacturing company/facility, =e4 , ow density s' le family homes, ranchettes, and ag buildings. Current zoning i Ais ill not change. Municipal sewer will probably never serve this area, at least not o eral decade: Page -1- Chesney Consulting
