No. 627 <br /> 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 <br /> November 24 , 1992 <br /> DEC 2 1 1992 <br /> Richard Raiche <br /> 280 Orono Orchard Rd. <br /> Orono, Henn. Co. , MN <br /> A Site Evaluation was completed on this property for_0n-Site Sewage <br /> Treatment. <br /> This site has an existing failing system with surface discharge <br /> due to strong clay soils & a high seasonally high water table, <br /> mottled soil ( highest known saturated layer of soil) . <br /> Soil borings indicate a Pressurized Mound System will need to be <br /> installed for repalcement. For a five bedroom home the area <br /> needed is approx. 40 ' x115 ' . The only available area is located <br /> south of the driveway at the base of a slope. This area is low <br /> and to install a system recommend to install an Interceptor Drain <br /> uoslope of the system. Also the area has potential for flooding. <br /> A diversion will need to be excavated to drain overflow from a pond <br /> south of this area. The diversion may be drained to the northeast <br /> to a wetland. This area is low and is not the best soil for locating <br /> a Pressurized Mound System but is the only area available. <br /> Additional Soil Borings & Percolation Tests will need to be completed <br /> to complete a Design for this property. See Site Plan for available <br /> area. <br /> Steven B. Schirmers CU <br />
