Dog Kennel Building-Soil Suitability Study Page 5 of 13 <br /> Our Project Number: NA157000G <br /> June 2, 2015 <br /> 3.0 EXISTING AND PROPOSED SEPTIC TANK USAGE <br /> 3.1 Existing On-Site Septic Tank Usage <br /> Septic permits were requested from the San Joaquin County Environmental Health Department <br /> (EHD) for the address of 26666 Hansen Road, Tracy, California. Based on a review of the EHD <br /> permits, a septic system already exists on site to serve the residence located at the southeast <br /> corner of the site. According to the EHD Onsite Wastewater Treatment System Permit <br /> (#SR0045749) dated February 7, 2006 the existing septic system consists of a 1,600 gallon <br /> concrete septic tank connected to four 100-foot long leach lines. According to the permit, the <br /> septic system is located approximately 200 feet from the nearest onsite water well. <br /> 3.2 Site Specific Permit History <br /> A total of six permits (two septic permits and four well/pump permits) were found at the EHD for <br /> the site address of 26666 Hansen Road, Tracy, California. The following is a list and <br /> description of the permits provided by the EHD: <br /> Approx.

We <br /> counted the building clusters within one square mile of the site, and made the assumption that <br /> each building cluster has one septic system. Using this method, we determined that there is an <br /> average of 16 septic systems per square mile in the immediate vicinity of the site. <br /> ©2015 Neil O.Anderson&Associates,Inc.A Terracon Company <br />
