Existing and Proposed Septic Tank Usage Existing Septic System A septic system is currently located on the Site to serve the existing house (Plate 2). Proposed Septic System A new septic system will be constructed for the proposed new home. On-Site Septic Permit History The San Joaquin County Environmental Health Department septic permit files were searched for the Site address; one permit was identified. The permit, dated August 1995, was for a repair to a residential septic system. A 65-foot leach line and a 36-inch diameter seepage pit were added to the existing system. The permit has been included in Appendix 4 of this report. 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 180 septic systems per square mile are located in the immediate vicinity of the Site. The Site is located in a small neighborhood of rural residences surrounded by agricultural land, mainly orchards. 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, most septic systems in the area utilize leach lines with seepage pits; two permits indicated leach lines with sumps. 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. The new septic system design should be based on the San Joaquin County On-Site Wastewater Treatment Systems Standards (2017) or other engineering recommendations. LOGE 2614 Page 2
