June 16 2000 <br />Re: Soil Boreings, Percolation Tests, System Design. <br />Brian Kerber <br />740 Orchard Park Rd <br />Orono <br />We were retained by Brian Kerber to provide criteria for the on-site sewage system for the <br />property located at 740 Orchard Park Rd. In the City of Orono <br />There were a total of 6 soil borings and 4 percolation tests done on this site and it appears that <br />there is room for a new primary arxi alternate sites for septic systems on this property. <br />This is based on a three bedroom, type one, single family home with maximum flow of 450 <br />gallons per day. This house exists on this lot at this time. <br />From these tests it was determined that a high water table exists at a depth of 16 to 24 inches <br />below the ground surface. The high vrater table determines that only a mound type drainfleld <br />may be installed, to meet with code. <br />Percolation tests range from 6 to 12 minutes per inch on the two sites tested. <br />All neighboring wells are located greater than 100 feet from the proposed drianfield site. <br />See attached sketch for locations. <br />These areas must be protected from any traffic to be used for any future septic sites. If they are <br />not protected the data collected herein will become Void and new testing shall have to take <br />plac«. <br />This design is in compliance with local codes and Minnesota Pollution Control Chapter 7i <br />of the date listed above. <br />Respectfully <br />Bob Volkenant <br />MPCA Ucense #56 <br />M f\ <br />ft <br />0 <br />1
