File No. 20-2949-11 <br /> JkT] 'KLEI ELDER <br /> December 20, 1990 <br /> On July 24 , 1990, our representative returned to the site <br /> to perform the 3-foot deep percolation test. As per San <br /> Joaquin County guidelines, the test was performed for a <br /> period of 4 hours. The last 30 minutes of the test were <br /> used to calculate the percolation rate. In order to use <br /> standard leach lines, the County requires a percolation <br /> rate of 60 minutes per inch, or faster, at the 3-foot <br /> depth. The 3-foot deep test performed passed with a <br /> percolation rate of 15 minutes per inch. The county <br /> approved percolation test sheet is ,. included with this <br /> report. <br /> ITEM C-3• <br /> "The depth and gradient of the groundwater table. " <br /> During our residence surveys on July 20, 1990, we were able <br /> to measure groundwater in 3 wells. The groundwater was <br /> measured at between 22 feet (location 5 on Plate I) and 33 <br /> feet (locations 3 and 4 on Plate I) below existing ground <br /> surface. Groundwater was estimated at approximately 29 and <br /> 31 feet deep by the 2 other well owners, where measurements <br /> could not be obtained. Regional groundwater maps published <br /> by the San Joaquin County Flood Control and Water <br /> Conservation District, Plate II, indicate groundwater in <br /> this area was approximately 30 feet below existing ground <br /> surface in the fall of 1989. <br /> This completes our scope of work at this time. Based on <br /> the above information, it is our opinion that the proposed <br /> 1-1/2-acre parcel is suitable for septic system use. We <br /> note that our scope of services did not include a detailed <br /> evaluation of the potential for the septic system to affect <br /> Copyright 1990 Kleinfelder, Inc. 3 <br />
