i <br /> Greenhagon Evaluation&Design <br /> 816 So. 10th Street 4 } <br /> Delano, MN 55328 AUS <br /> August 13, 1996 <br /> Bob Kurzhals <br /> 325 Old Crystal Bay Ro d <br /> Long Lake,MN 55356 <br /> SITE SUMMARY <br /> After conducting soil borings across this site, I have come to the nclusion that there is one to two <br /> feet of fill on the entire site. There also is mottle in at 9 to13 incheow the surface in the filled soil <br /> in the mound area. Due to these conditions, this system is an AlI emative septic system per code <br /> 7080.0910 and must be approved by the State of Minnesota and t e City of Orono. The only other <br /> option for this site would be holding tanks. <br /> In order to protect public health and extend the life of this system,it h s been oversized. The rock bed <br /> area has been increased from 374 square feet to 450 square feet,an the sand under the rock bed <br /> has been increased to two feet,three inches to give three feet of se ration. It is also suggested to <br /> rough the soil extra deep to loosen the fill. The City of Orono inspect its septic systems every two <br /> years and will schedule additional inspections if a problem is detected on regular inspection. <br />
