I. INTRODUCTION This report issues my findings regarding the Nitrate Loading Study, Soil Suitability Study and wastewater disposal operational parameters for the existing Jacob's Brothers Produce Stand. These studies were required by the San Joaquin County Environmental Health Department(EHD) and comply with the San Joaquin County Development Title, specifically Section 9-1105.2(d). Mr. Andrew Sephos is the owner of the subject property, and the developer of this project. Mr. Hector Jacobo is the operator of the Produce Stand. Mr. Sephos has provided the preliminary information to complete these studies. The Site Plan and associated civil engineering information are in the production process and were not completed as of the date of this report. Since the City of Manteca sewer and water have not expanded to the subject property,the new site improvements will operate with an existing domestic well, and a new on-site domestic wastewater disposal system. A small building to house the fruit stand, and approximately one acre in vegetable production compose the northernmost portion of the property, with the balance as fallow land. It is presently unknown when City of Manteca utilities are expected to serve the property. SSS§ 1.2 The total Parcel area is QOOO acres. The project site is near the east end of the city limits of Manteca, approximately 1east of the Austin Road intersection, on the south side of Highway 120. The majority of land use of the property has been fallow, as illustrated on the San Joaquin Parcel Viewer Map. It is proposed to improve the Produce Stand with individual Men's and Women's public restrooms,__ These proposed improvements will be illustrated on the Site Plan, to be submitted to the EHD. The purpose of these Studies was to collect the following information to fulfill EHD requirements and discuss septic system operational parameters to facilitate the transfer of information to EHD: • To: 1.)Analyze the capacity of the indigenous soils in the proposed disposal area to accept the anticipated wastewater flows, 2.)Assess the characteristics of the soil to mitigate nitrate impact, and 3.)Discuss operational parameters to achieve the two goals of proper wastewater management and nitrate loading mitigation for the proposed leachfield disposal area. This was accomplished by the referenced testing,physical/chemical analyses and operational parameters incorporated into the wastewater disposal system. • Conduct soil physical and chemical testing for determination of the following: Physical testing included percolation testing and particle size analysis of the soil characteristics underlying the effluent disposal area. Chemical testing included analyses for the constituents that influence nitrate loading. • Chemical Analysis and Mounding Analyses of the water table underlying the proposed leachfield area were not conducted. Chemical analysis of the underlying groundwater was obtained from the existing domestic well that also provides water to the aforementioned small ag production acreage. The underlying soil is very sandy which makes the potential for a mound sufficient to affect the operation of the septic system virtually impossible. 1 Chesney Consulting
