jcriON <br />II. HOW TO USE THE SOIL MAP <br />TMs is a prelifliijiaTy soils evaluation and plan review of the pro­ <br />posed Orono Oaks Addition in the City of Onmo. <br />A detailed soils map for the area of proposed development is provided <br />with this report. This map is based on information contained in "Soil <br />Survey of Hennepin County** and "Landscapes of Henn^in County" as well <br />as 1975 aerial photograi^ of the area and an on-site investigation. <br />Each of the soils mapped within the proposed development ar^ is briefly <br />described. Favorable and unfavorable development characteristics are <br />discussed. Explanations of the soil map syn^ls and colors are pre­ <br />sented in Sections II and III. <br />This is a preliminary soils evaluation and additional engineering tests <br />should be conducted before construction is begun. <br />The potential of the soils mapped for installation of <br />ment systems is discussed. <br />Areas within the proposed develop^t area which may be classified as <br />public waters or wetlands are indicated. <br />Methods for control of runoff and sediment from this site are discussed. <br />To use the soil map one needs to know ^diat the symbols mean. The soil <br />symbol consists of tluree parts arranged as follows: <br />HbB2 - Hb <br />(Soil) <br />B <br />(Slope)(Erosion) <br />The first two letters denote the soil type; 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 Erosion Legend <br />0 to 2 percent <br />2 to 6 percent <br />6 to 12 percent <br />12 to 18 percent <br />18 to 35 percent <br />No Syn^l - 0 to 1/3 topsoil lost. <br />2 - 1/3 to 2/3 topsoil lost. <br />3 - More than 2/3 topsoil lost. <br />The soil types found in this area were classified according to the **Soil <br />Survey Report of Hennepin County*', and the standards of the National Co­ <br />operative Soil Survey.
