I. INTRODUCTION This report issues my investigative findings regarding the Nitrate Loading and Soil Suitability Studies conducted for the project referenced on the Title Page. These Studies were required because of new regulations enacted by the San Joaquin County Environmental Health Department (EHD) to determine if nitrate loading standards would be exceeded when improvements occur on a subject Parcel. Specifically, concerns regarding nitrate loading could potentially occur when primary unit dwellings are constructed on comparatively small parcels. SSS§ 1.1, 1.2. Mr. Tony Noceti is proposing to construct a primary residential structure on a Parcel owned by him. The subject Parcel is too small to ever construct a second unit dwelling. This primary residence will have two bedrooms and two baths and will be served by City of Stockton water. SSS§ 1.3. The property is 0.23 acres as illustrated on the Assessors Parcel and District Viewer Maps and is surrounded by the town of town of French Camp to the north, west and south, and agricultural production land to the east. Within the text of this Report, Bolded Section (§) numbers are referenced at the beginning of an applicable Paragraph(s), or Appendices that correspond with the EHD Requirements Checklist. Section Numbers referenced as SSS§, are sections applicable for the Soil Suitability Study Requirements Checklist. Section Numbers referenced as NLS§, are sections applicable for the Nitrate Loading Study Requirements Checklist. Other portions of text may also apply to other sections of the Checklists, but may not necessarily be referenced. The following summarizes the investigative parameters included to complete this report: Two percolation tests were performed for this study in the proposed location of the future filter bed disposal fields (2). Test results indicate permeable soil at both the shallow leachline depth and at the deeper sump depth. Soil chemical testing was conducted on two samples retrieved from the percolation test borings. Physical testing of the soil sample included texture particle size analysis for sand, silt and clay content, and chemical testing analyses for the constituents that influence nitrate loading. The nitrate loading to the on-site soils in combination with nitrate impact potential to the underlying groundwater from percolating effluent was found to exceed the acceptable Maximum Contaminate Level (MCL) by Federal Standards. Nitrification prevention procedures and naturally occurring nitrification measures are described in this report. II. SOIL SUITABILITY STUDY FINDINGS NLS§ 1.1. The UC Davis Soil Web Map indicates the Map Unit Name to be a Veritas fine sandy loam, 0 to 2 percent slopes (266). As referenced, soil samples were retrieved from the 3 ft and 8 ft deep perc test borings for physical and chemical analyses. Page -1- Chesney Consulting
