Proposed Septic System Mr. Kelly plans to construct a new septic system for the new residence. On-Site Septic Permit History The San Joaquin County Environmental Health Department permit files were searched for the Site address. No septic permits were identified. Existing Septic Tank Usage in the Vicinity To estimate the septic system usage in the area, our office counted septic systems that exist within approximately one square mile surrounding the property. Air photo imagery from Google Earth was used. Each building cluster on the photo was assumed to have one septic system. Using this method, it is estimated that at least 75 septic systems per square mile are located in the immediate vicinity of the Site. The Site is located approximately 300 feet west of the town of Acampo. Outside of the town, most of the surrounding properties are vineyards. Septic Permit History in the Vicinity Based on a review of septic permits on file at the San Joaquin County Environmental Health Department for nearby properties, septic systems in the area typically utilize leach lines, leach lines with 25-foot deep seepage pits, or leach lines with sumps; one permit indicated a 7-foot deep trench system. The septic permits can be found in Appendix 4 of this report. Expected On-Site Maximum Septic Tank Usage Maximum expected usage on the Site would be from the current and future residents of the Site. Septic system design should be based on the San Joaquin County On-Site Wastewater Treatment Systems Standards (2017) or other engineering recommendations. Ground Water Information Depth and Gradient Live Oak reviewed ground water elevation information available from the San Joaquin County Flood Control and Water Conservation District to determine the ground water levels near the Site. Data from the fall of 2017 and the spring of 2018 were the most recent available from this source. According to an analysis of these maps (Plates 4 and 5), ground water elevation is approximately 10 to 15 feet below mean sea level. Ground water appears to flow to the northeast at a rate of approximately 8 to 16 feet per mile. LOGE 2132 Page 2
