I . ItiTROI UCTI(T. This is a preliminary soils evaluation of the proposed Farm at Long Lake Addition in the Cite of Orono. A detailed soils map for the area of proposed development is provided with this repot-. This map is based on information contained in "Soil Survey of Her, spin County" and "Landscapes of Hennepin County" as well as 19"5 aerial photographs of the area and an on -site investigation. Each of the soils mapped within the proposed development area is briefly described. Favorable and unfavorable development characteristics are discussed. Explanations of the soil map symbols and colors are pre- sented in Sections II and III. This is a preliminary- soils evaluation and additional engineering tests should be conducted before construction is begun. The potential of the soils mapped for on -site treatment of septic tank effluent is discussed. II. HOW TO USE THE SOIL MAP To use the soil map one needs to know what the symbols mean. The soil symbol consists of three parts arranged as follows. HbB2 - Fib B 2 (Soil) (Slope) (Erosion) The first two letters denote the soil type; the last letter is the slope of the land in percent, and the absence or presence of a number indicates the degree of erosion. Slope Legend A - 0 to .1 percent B - 2 to 6 percent C - 6 to 12 percent I) - 12 to 18 percent E - 18 to 35 percent III . SOIL. TYPES PRESENT Erosion Legend No Symbol - 0 to 1/3 topsoil lost. 2 - 1/3 to 2/3 topsoil lost. 3 - More than 2/3 topsoil lost. The soil types found in this area were classified according to the "Soil Survey Report of Hennepin Court y", and the standards of the National Co- operative Soil Survey.
