File No. 20-3566-01r T <br /> March 19 , 1992 <br /> Reference is made to Plate I of this report which shows the <br /> location of the George property. The majority of the site <br /> area consists of agricultural and pasture land with <br /> scattered residences. <br /> On March 6, 1992 , a representative of our firm visited <br /> three residences located off Priest Road. The purpose of <br /> the visits was to obtain information on septic system use <br /> and to inquire about any problems known to exist with this <br /> method of sewage disposal. None of the residents <br /> questioned reported having problems with the performance of <br /> their septic systems. We were informed that their private <br /> wells produced "good" quality water. <br /> ITEM C-2 : <br /> "The suitability of the soil for development <br /> systems; " utilizing septic <br /> On March 11, 1992 , a representative of our firm drilled and <br /> set-up one 3-foot deep percolation test hole on each of the <br /> three proposed parcels. The test holes were <br /> hand drilling drilled with <br /> equipment using <br /> continuous-flight auger. Perforated PVC pipe wasdiameterinserted <br /> into the test holes to prevent disturbance when adding <br /> water. On March 12, 1992, the test holes were filled with <br /> relatively clean water and left to soak overnight. <br /> On March 13 , 1992 , our representative returned to the site <br /> to perform the percolation tests. <br /> As per J <br /> County guidelines, the tests were performed forsan a perioduin of <br /> 4 hours. The last 30 minutes of each test were used to <br /> calculate the percolation rates. In order to use standard <br /> leach lines, the County requires a percolation rate of 60 <br /> minutes per inch, or faster, at the 3-foot depth. The <br /> three tests performed passed with percolation rates of 10, <br /> 10 and 9-1/2 minutes per inch for parcels 1, 2 and 3 , <br /> respectively. The approximate locations where the <br /> percolation tests were performed are shown on Plate I. The <br /> County approved percolation test sheet is included with <br /> this report. <br /> ITEM C-3 • <br /> "The depth and gradient of the water table; " <br /> During our residence surveys on March 6, 1992, we were able <br /> to measure groundwater in two wells. The groundwater was <br /> measured at approximately 33 feet below existing ground <br /> surface.
