I. INTRODUCTION This Report issues my findings regarding the Nitrate Loading and Soil Suitability Studies completed for the proposed warehouse Buildings referenced as A&B of the Holly Commerce Center, also known as the North Tracy Commerce Center. These studies were completed to examine the surface and subsurface soil textures and soil chemical characteristics, and the chemistry of the underlying water table to determine the suitability and subsequent design of the on-site wastewater management system. In addition, the findings correlate the soil and underlying water table analyses with the nitrate loading potential from the future wastewater disposal system to serve these two Buildings. Siegfried Engineering, Inc. has provided the civil engineering for this project, and the data and design criteria for the effluent disposal system. This has also been correlated with the findings of these Studies. This report complies with San Joaquin County Development Title, Section 9- 1105.2(d). 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 with a Checklist Section Number. NLS§2.3, SSS§3.1. The subject property is located in the immediate southeast corner(SEC) of the intersection of Sugar Road and Holly Drive. Tracy municipal water services will.provide domestic water for the project;therefore,there are no domestic well(s)on the subject parcel. There are no septic systems on the property and it may be decades before municipal wastewater services become available. SSS§ 1.1, 1.2. The SJC District Viewer and.APN Maps indicate the subject Parcel is 110.35 acres with no buildings on the property where the proposed A&B Buildings are to be constructed. Grading procedures are in the process of formulation. General plan and current zoning are denoted on the Cover Page. The testing protocol has found the indigenous soils under the four test locations to contain a predominate lean clay soil material. The soils possess a slightly below average permeability,with the perc test in the SWC of the property having a failing perc rate. Given that all other tests had passing rates, this perc test result is deemed an anomaly. Page -1- Chesney Consultina
