I. INTRODUCTION This Report issues my findings regarding the Nitrate Loading and Soil Suitability Studies completed for the Holly Commerce Center project. These Studies were completed to examine the underlying soil structure and characteristics to determine the suitability of an on-site decentralized wastewater management system, commonly referred to as a septic system, and to design it accordingly. These Studies provide the San Joaquin County Environmental Health Department (EHD) with their required information pertaining to the current status of the soil and underlying groundwater, regarding the nitrate loading potential from the current and future wastewater disposal systems on the subject Parcel. This report complies with San Joaquin County Development Title, Section 9-1105.2(d). The owner of the property, Mr. Steve Cortese, has provided the preliminary information to complete these Studies. 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 Check/lists, but may not necessarily be referenced. NLS§2.3', SSS§ 3.1. The subject property is located north of the 205 Freeway, near the City of Tracy Wastewater Treatment Facility. Tracy municipal water services have expanded to this area although it may be a number of years before wastewater services become available. The attached Site Plans illustrate the available industrial buildings for lease. The map in Appendix B illustrates the industrial buildings with and without bathrooms and are referenced with Letters. The EHD Studies for this project and the associated design criteria, specifically pertain to retrofitted Restrooms in Building G, with the generated wastewater disposal through a pressurized filter bed system in a dedicated area southeast of these new Restrooms. SSS§ 1.1, 1.2. The SJC District Viewer Map indicates the subject Parcel is 164.28 acres with the referenced buildings on the property. Present land use of the property can be observed by the attached Site Plans and aerial Google Maps. Current and future zoning is I-G, General Industrial. The testing protocol has found the indigenous soils under the test location to contain a predominate lean clay soil material possessing a slow permeability, which was to be expected given the soil's clay content. Percolation test results reveal a perc rate slightly exceeding the maximum allowable rate, thus the requirement for an engineere isposal system. I Page -1- Chesney Consulting
