rl (§ 1.0) INTRODUCTION 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 determine if the proposed two Parcels to be created from this subdivision 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. §02 ) SUBJECT SITE AND STUDY AREA BACKGROUND INFORMATION /A§ 1" 1. , 2 1 ) T e s o'ect i to s iv'de an exi tin 10.0 acre Parcel into two 5-acre.�arcels denoted as„Parcel 1 and a Designated Remainder. It is proposed to construct single family residential (SFR) structures on both Parcel 1 and the Designated Remainder. Parcel 1 is presently open, vacant land, while the Remainder contains the Andrews"home, a barn, a storage building, and a small greenhouse type structure. A septic system and domestic will exists for the Andrews' residence. It is proposed to connect the new residence on the Designated Remainder to the existing well. This new home will have its own septic system. The new home on Parcel 1 will have its own domestic well and septic system. Each parcel area and orientations are denoted on the attached Tentative Map, found in Appendix ✓A.W§a It is possible EHD would support a second unit dwelling on proposed Parcel 1. The new home on the Remainder Parcel can be considered a second unit dwelling. This gives a total of three septic systems on the two Parcels comprising 10 acres. This is a density of one septic system per 3.3 acres, which can be considered low. Taking the possibility of a second unit dwelling on Parcel 1 for a total of four systems on 10 acres, gives 2.5 systems per acre, which can be considered a medium-low density. /(§1. ar"1) The subject property is 4.5 miles east of Acampo, northeast of the intersection of Jahant Road and Bryant Road. Surrounding property use consists predominately of low density single family residences, ranchettes, pasture, and confined animal facilities such as horse ranches, and other types of ag buildings. Current zoning is � 5. Municipal sewer will probably never serve this area, or at least not for several decades.( �Any of the above land use could create environmental concerns that may be discovered in the future. Groundwater nitrate concentrations w due to a low densit of se tics stems and low densi a icultural roduction land. As depicted on the attached USGS Map and the Tentative Map, the topography of the site is 93 feet above MSL, with a very slight land declination toward the southwest. Therefore, septic system design criteria for slopes do not have to be considered. Page -1- Chesney Consulting
