INTRODUCTION This Soil Suitability Study presents the results of our investigation concerning the soil strata and groundwater under the subject property referenced on the Title Page. Our study was completed to satisfy the requirements of the San Joaquin County Environmental Health Department for their support of a proposed zoning change for this project. Specifically, the Environmental Health Department is requiring 1.)Determine if the indigenous soils are conducive to accept effluent flows for the anticipated lifespan of the current and future on-site septic systems, 2.) Sample and test the underlying soil for nitrate-nitrogen content to assess the potential for nitrate leaching from the vadose zone, 3.) Sample and test water from the water table, or top unconfined aquifer to analyze it for current nitrate impact, 4.)Review the files at the Environmental Health Department for historical nitrate concentrations and ensure the Public Water Supply serving the Bogetti facility is currently in compliance, and 5.) Provide recommendations based upon the environmental criteria encountered in this study. Our 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. SUBJECT SITE AND STUDY AREA BACKGROUND INFORMATION It is our understanding that the purpose of this project is to change the zoning of the subject parcel to accommodate certain businesses that Mr. Bogetti would like to operate, or have small business people/independent contractors operate. The subject property is currently under General Plan A/G with the zoning as C-X, and is located on the border between San Joaquin and Stanislaus Counties. It is proposed to file for re-zone to C-RS, commercial - rural services. The attached SITE DEVELOPMENT PLAN Map as drawn by R. B. Welty and Associates of Modesto, California illustrates the designations and orientation of all the businesses associated with the subject property. These include a United States Post Office, the Orchard Restaurant, Gift Shop, Service Station, Tire Shop, Day Care, Barber Shop, Water Park and a Recreational Vehicle (RV)Park. All these present and fixture facilities are, or will be,tied into the existing septic system. Additional septic system capacity may be needed, which will be dependent upon future wastewater flows. As referenced in the Introduction, soil testing for effluent acceptance was a requirement of the Environmental Health Department. The domestic well that serves the facility is denoted on this Site Development Plan map. The topography of the site is relatively flat; therefore, design criteria for slopes in the leachfield area will not have to be considered. On-site stormwater drainage flows away from the existing structures and onto the surrounding open land, or in drainage ditches adjacent to the existing roads. Drainage does not appear to affect the existing septic systems either near the RV Park, or Page-1- Chesir Consulting
