Home My WebLink About1990 - Site Evaluation Report SITE EVALUATION REPORT FOR JUDY PIERPONT ON LOT 14 , BLOCK 1 , THE FARM AT LONG LAKE ORONO, MINNESOTA 8-9-90 On August 6 , 1990 an alternate drainfield site was tested on the adjoining lot to be added to the current property owned on Lot 15 and part of Lot 16 . Two soil borings were taken and three percolation holes tested with an average percolation rate of 10 . 9 minutes per inch. With the possibility of a high seas- onal water table however, a pressure mound system would be re- quired should this area ever be used. At that time, a specific system design would be needed. If any additional information is needed, please contact me. Sincerely, PERCOR, INC . Mark S .
