Page -a- 11 'led ium Green U t;rL n L Pa rk Green Iiavden loam: This is a deep, well -drained soil that fornckl in loa:7iv 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 linne- 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. Hayden loam - 2 to 6 perCLAt slope: The map symbol for this soil is HbB and the map color is nedium =_reen. this is a gently undulating soil occupying areas on knolls and hillsides. This soil is well -drained and therefore never saturated although si.ie hill seepage is not uncommon around basement halls (luring rainy seasons ur spriru., thaws. The rolling slopes offer attractive build g sites. Soil strength is adequate. Shrink -swell (volume change) is low to mod- erate with changes in moisture )ntent. The soil is moderately perv- eable. Erosion is a hazard if the soil is left exposed for extended Periods.
