12172 N Hibbard Road Project No. 2021-00063 P a g e | 9 <br />7.2 Expected Maximum Septic Tank Usage for Site <br />Expected maximum septic tank usage for the Site is to accommodate the current three-bedroom, <br />single-family residence and the proposed three-bedroom, two-bath, accessory dwelling-unit. <br />7.3 General Area Septic Tank Usage, Permit, and Repair History <br />In an attempt to determine the septic system density for the vicinity of the site, our office reviewed a <br />recent aerial photograph available from GoogleEarthTM. We counted the clusters within <br />approximately one square mile of the site, with the assumption each building cluster has one septic <br />system. Using this method, we determined there are approximately 90 septic systems per square <br />mile in the immediate vicinity of the site. This is a low number of septic systems, with the majority of <br />these systems located within a rural residential subdivision. <br />The EHD septic permit files were obtained from the San Joaquin Environmental Health Department <br />(EHD) Online EHD Program Records6 in an effort to obtain copies of permits for any septic tanks <br />located within the general area of the subject property. <br />Copies of the septic search permits for surrounding parcels have been included in Appendix D of this <br />report. The records are summarized in the following table: <br />Table 5. <br />Neighborhood Site Sewage Disposal System Permits <br />Address Date Permit Comments <br />12156 N Hibbard Road <br />APN: 063-230-43 <br />Issued 03/21/2007 Installation Permit <br />SR0050052 <br />New installation of a septic tank, 2 <br />leach lines, and 2 seepage pits. <br />12254 N Hibbard Road <br />APN: 063-230-15 <br />Issued 08/11/1971 <br />Issued 10/20/1981 <br />Issued 09/28/1998 <br />Installation Permit 71-742 <br />Repair Permit 81-685 <br />Repair Permit SR0017651 <br />New installation of a septic tank, 2 <br />leach lines, and 2 seepage pits. <br />Seepage pit repair. <br />Seepage pit repair. <br />12104 N Hibbard Road <br /> APN: 063-230-13 <br />Issued 07/06/1972 <br />Issued 03/22/1991 <br />Permit 72-699 <br />Permit 91-0645 <br />Repair/Addition of 1 leach line and <br />1 seepage pit. <br />Septic tank repair. <br />12131 N Hibbard Road <br /> APN: 063-230-35 <br />Issued 10/30/1978 <br />Issued 05/28/1991 <br />Permit 78-949 <br />Permit 91-1266 <br />Septic system replacement with <br />leach lines and seepage pits. <br />Repair/addition of one leach line <br />and seepage pit. <br />6 https://lfweb.sjgov.org/WebLink/Browse.aspx?dbid=1&cr=1 accessed September 9, 2019
