JJuun • 1. 1981 <br />soxe <br />Ways HN 95391 <br />r, <br />Mr. Richard r3nry ' <br />21350 Excleslor Boulevard <br />Excelsior, Minnesota 55331 <br />Dear Hr. 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 the 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 Cary Gabriel). A log of the soil borings is also enclosed. <br />The soil borings reflect a uniformly high water table throughout the area <br />tested. This condition prohibits the installation of conventional soil absorption j <br />systems and shallow trench systems. The percolation rates encountered and the <br />gentle slopes on this site would indicate that sound systema should be satisfactory <br />on each of these lots. We recormend that the future homes be provided with ssoued <br />systems of soil absorption. <br />Please call if you have any questions. <br />Thank you. <br />Yours very truly <br />� <br />QG . % C <br />Carl W. Borg. P.E. <br />
