I. INTRODUCTION This Report issues my findings regarding the Nitrate Loading and Soil Suitability Studies completed for the proposed ZipCubes Storage Facility to be located at the address referenced on the Title Page. These Studies were completed to examine the underlying soil structure and characteristics to determine the suitability of a septic system, and design it accordingly. The Studies also provide the San Joaquin County Environmental Health Department (EHD) with their required information. This report complies with San Joaquin County Development Title, Section 9-1105.2(d). The project manager, Mr. Bjorn Ervell, has provided the preliminary information to complete these Studies. Although a septic system exists for the existing building, a new system must be installed for this proposed improvement project. The current wastewater disposal system consists of one unisex restroom with a toilet and sink, with wastes flowing to a small (approx. 750 gallons)plastic septic tank. Effluent from the tank then flows to an unknown and indeterminable leachfield. Consequently, a new system must be engineered for the proper disposal of effluent, along with all remaining requirements such as the 100% replacement area. 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. NLS§ 2.3 SSS§ 31. The subject property is located on the north side of I I' Street, east of the City of Tracy. There are no City of Tracy municipal water, sewer and/or stormwater management / services. Consequently, the property must have its own well, septic system and on-site stormwater retention system, which is located in the back of the property. It will be a number of years before water, wastewater and stormwater services become available. SSS§ IA, 1. The Aerial photo in Appendix A illustFates the layout of the property. The SIC District Viewer Map indicates the subject Parcel is 5.01 acres. Present land use of the property is r largely vacant. Current and future zoning is C-G; General Commercial. The testing protocol has found the indigenous soils under the proposed filter bed disposal area location to contain a predominate lean clay loam soil material possessing a rapid permeability, which is commonly observed in the clay soil types of the Tracy area.
