Page -.i- <br />Erin clav loam: <br />This soil has the same characteristics as the Erin loam. The difference be- <br />tween the two soils is that between 1/3 to 2/3 of the topsoil has been lost <br />from the Erin clay loam. There are several slope phases of this soil mapped <br />in Hennepin County. Each slope phase mapped within the area of proposed develop- <br />ment will be discussed separatel,.. <br />Medium Erin clay loam - 2 to 6 percent slope, eroded: <br />Red <br />The map symbol for this soil is ErB2 and the map color is medium red. This <br />is a gently undulating soil occupying irregular hillsides and lMolls. Because <br />this soil is eroded the surface layer is clay loam. The soil is well -drained <br />and therefore never saturated. Sidehill seepage is not uncommon however, around <br />basement wale during rain), seasons or spring thaws. The rolling slopes offer <br />attractive building sites. Soil strength is adequate for residential develop- <br />ment. Shrink -swell (volume change) -s moderate with changes in moisture content. <br />The soil is slowly permeable. Erosion is a hazard if this foil is left exposed <br />for extended periods. <br />.:U':I Glencoe silty clay loam: <br />luc <br />The map sNinbol for this soil is Gc and the map color is medium blue. <br />This is a deep, very poorly drained soil. The soil was formed in <br />T t loamy collurium over calcareous loamy till. The soil is nearly- .:�cl <br />occupying; depressions and drainageways. The native vegetation was <br />dominantly sedges and wetsite Grasses. IXiring wet periods '):' the <br />year the w•atertable is within i foot of the surface and po: ing may <br />occu.•. The high organic matter content in the upper soil horizons <br />means the soil has low bearing values. There is a high potential <br />for frost action. <br />pled i inn f_lamel 1 oam : <br />blue <br />he map syr�bol for this soil is IU and the map is r^• , ;,� glue. <br />This is a d --p, poorly drained soil that fo--me nv colluvium over <br />'loam,. till. 7lie soil occurs in short, narrow dr aays cn foot <br />and in Ion,, winding drainages%ays betwe,,n krolis a.. .11s. the native <br />vegetation was mainly sedges, grasses and sc:attere� poplar trees.
