Lot <br />1 was tested for both a primary and alternate site with 6 percolation <br />holes tested and 3 soil borings. Lot 2 which contains the main house <br />teas tes roc; only for an alternate site should tine present system ever <br />fail and thus 2 percolation holes were tested and 1 soil boring ta- <br />ken. Lot 3 was tested for a primary site for the existing guest house <br />near the lake since the present system is non -conforming and thus 4 <br />percolation holes were tested and 2 soil borings taken. <br />All areas tested yielded fast percolation rates and had no.high <br />water table problem and would be acceptable f)r standard drainfield <br />systems. Lot 2 was tested north of the main house and a little east <br />of the present tanks and drainfield area. However, should this area <br />ever be used, a pump and pumping tank would be required to serve the <br />higher lying new drainfield area. <br />Lot 1 should have no problems and probably could be served by <br />gravity flow depending on the exact location and elevation of a <br />future new house there. <br />The drainfield area for the guest house on lot 3 has a very <br />fast percolation rate and thus a smal-er drainfio:.d area wiles ba <br />requir,3d. _'.1e area tented was above the swale so as not to allow run- <br />off water to enter. However, it appears some underground water pipes <br />and electrical wires run through or near this area and these nuat be <br />located and possibly relaid during drainfield construction. <br />If any other irfor-ation is needed please notify me. <br />Sincerely, <br />P RCOR, <br />I1 11C., <br />1 -:ark 3.
