INTRODUCTION <br />'fhis is a prcliminaiy soils evaluation and plan review of the proposed <br />D. F. Vetter Addition in the City of Orono. <br />A detailed soils map for the area of proposed development is provided <br />with this report. Tliis map is based on infomiation contained in "Soil <br />Survey of llenjiepin Coiuity" and "Landscapes of Ilennejiin Coujity" as well <br />as 1975 aerial photographs of the area and an on-site investigation. <br />Each of the soils mapped within the proposed development area is briefly <br />described. Favorable and unfavorable development characteristics are <br />discussed. Explanations of the soil map s>inbols and colors arc pre­ <br />sented in Sections II and III. <br /># <br />This is a prelininaiy soils evaluation and additional o]iginoei'ing tests <br />should be conducted before constniction is begun. <br />The potential of the soils mapped for installation of on-site soil treat <br />ment systems is discussed. <br />Methods for control of runoff and sediment from this site are discussed. <br />11. HOW TO USE niE SOIL MAP <br />To use tlie soil map one needs to Icnow what the s>mibols mean. The soil <br />s)inbol consists of three parts arranged as follows: <br />HbB2 = Hb <br />(Soil) <br />B <br />(Slope)(Erosion) <br />'fhe first tAvo letters denote the soil 1)^0; the last letter is the slope <br />of the land in percent, and the absence or presence of a number indicates <br />the degree of erosion. <br />Slope Legend <br />A <br />B <br />r <br />D <br />E <br />0 to 2 percent <br />2 to 6 percent <br />6 to 12 percent <br />12 to 18 percent <br />18 to 55 percent <br />^ro^ on_J .eg end <br />: ) Symbol - 0 to 1/3 topsoil lost. <br />2 - 1/3 to 2/3 topsoil lost. <br />5 - More than 2/3 topsoil lost. <br />m • SOIL TYPES rid-SENT <br />The soil ty]es found in this area were classified according to the "Soil <br />Sui"vcy Report of Hennepin Coimty", and the standards of the National Co­ <br />operative Soil Survey.
