I. INTRODUCTION Chesney Consulting has been retained by Mr. Tyrone Barber to complete this Nitrate Loading and Soil Suitability Studies report to fulfill the requirements of the San Joaquin County Environmental Health Department (EHD) for the proposed construction of an Assisted Living Facility, as referenced on the Title Page. These Studies were completed to examine the underlying soil structure and characteristics to determine the suitability of the proposed on-site wastewater treatment system (OWTS) correlated with projected effluent volume and characteristics and nitrate loading potential. 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. NLS§ 2.3, SSS§ 3.1. The subject property is located on the west side of Lawrence Road, approximately 150 ft north of the intersection of Lawrence Road and Arthur Road. There are no municipal water, sewer or stormwater management services in this locale. Consequently, the proposed facility must have its own OWTS and domestic well. An existing well that serves the buildings on the subject property will also serve the proposed Facility. It will be decades, if ever, before municipal water and wastewater management services become available to this area of northwest of Escalon. SSS§ 1.1, 1.2. The subject property is referenced on the attached District Viewer Map. The soil sampling procedures and texture analysis on these samples have found the indigenous soils under the proposed effluent disposal area to contain loam and sandy loam soil observed from a 23 ft exploratory/perc test boring. II. SOIL SUITABILITY STUDY FINDINGS A. SUBJECT PROPERTY AND SURROUNDING STUDY AREA INFORMATION SSS§ 1.1. The subject property currently contains a single family residential structure, outbuildings, and agricultural production (almonds). Surrounding study area consists of ranches and ranchettes, dairies, and agricultural production land, specifically permanent tree and pasture land crops. SSS§ 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 6.8. Permit applications within the one-half mile radius study area from the property were reviewed for repairs/replacements/additions to existing septic systems. Eleven permits for repairs/additions were found. This can be considered a high number of permits within the study area and indicates the proposed OWTS should compensate for this data.
