JuneAl, 1981 <br />Bo <br />ox <br />Wayz, MN 55391 <br />A <br />d <br />Mr. Richard Conry <br />21350 Exclesior Boulevard <br />Excelsior, rinnesota 55331 <br />Dear Mr. Conry: <br />We have completed a site evaluation for on-site sewage treatment facilities <br />on 6 lots located west of Willow Road in Orono, Minnesota. A location map has <br />been enclosed showing the location of Ll�e percolation tests, percolation data, <br />location of soil borings and relative elevations of the surface at the location <br />of the percolation tests. (For detailed contours please see topography prepared <br />by Gary Gabriel). A loo of the soil borings is also enclosed. <br />The soil borings reflect a uniformly high water table throughout the area <br />tested. 7;iis condition prohibits the installation of conventional soil absorption <br />systems and shallow trench systems. The percolation rates encountered and the <br />gentle slopes on this site would indicate that mound systems should be satisfactory <br />on each of these lots. We recorunend that the future homes be provided with mound <br />systems of soil absorption. <br />Please call if you have any questions. <br />Thank you. <br />ORONO <br />Yours very o uly,1 <br />Carl W. Borg, P.E. �— <br />.maw <br />sAw <br />
