Page -3- Mediiun Hamel loam: Blue The map symbol for this soil is Ha and the map color is medium blue. This is a deep, poorly drained soil that form(. -(I in loamy colluvium ove, my loatill. The soil occurs in short, narrow drainageways on foot slopes and in long winding drainageways between icno . and hills. The native veget.=tion was mainly sedges, grasses and scatLcr poplar trees. During wet periods of the year there is a perched watertable within 1 foot of the surface and ponding may occur. The high organic matter content in the upper soil horizons means the soil has low bearing values. There is a high potential for frost action. iiavden loam: This is a deep, well -drained soil that formed in loamy glacial till and occurs on gently sloping to very steep slopes on knolls and hillsides. The soil was strongly influenced by a forest environment in its develop- ment. The natural vegetation was mixed hardwood forest. Shale and lime- stone fragments as well as granitic cobbles and boulders are common through- out. Several slope phases are mapped in Hennepin County. Each slope phase mapped in the area of proposed development is discussed separately. "led..11ur, giayden loam - 6 to 12 percent slope: �;recn f— -1 The map symbol for this soil is HbC and the map color is medium gr^en. U This is a rolling soil occupying irregularly shaped areas on hillsides and knolls. This soil is well -drained and therefore never saturated although sidehill seepage is not uncommon around bas-nent walls during rainy seasons or spring thaws. The rolling slopes offer attractive building sites. Soil strength is adequate. Shrink -swell (volume change) is low to moderate with changes in moisture content. The soil is mod- erately permeable. Frosion is a hazard if the soil is '^ft exposed for extended periods. N1rk Havden loam 12 to 18 Percent slope: Green MMe map symbol for this soil is IN) and the map color is dArl, Vreen. This is a hilly soil occupying, irrein,larly shaped areas on hi' sides and knolls. This is a well -drained soil which never becom s _.aturated, however seeps may appear on sidehills durins spring thaws or rain seasons. There is a large erosion hazard if this soil is left ex;,osed. Site planning on soils such as this is more complex if the natural features of the terrain are to he maintained. Soil strength is adequate. Shrink -swell (volume chani,e) is lend to moderate with changeti in moisture content. The sail is noder:,tely permeable.
