z� Blue 2 Medium Blue 5 it Glencoe siltv clay loam: The map symbol for this soil is Gc and the map color is medium blue. This is a deep, yen• poorly drained soil. The soil was formed in loamy colluvium over calcareous loamy till. The soil is nearly level occi-r:ing depressions and drainageways. The native vegetation was dominantly sedges and wetsite grasses. During wet periods of the dear the watertable is within 1 foot of the surface .ind ponding may occur. T`P! high organic matter content in the upper soil horizons means the soli has low bearing values. There is a high potential for frost action. Hamel loam: The map symbol for this soil is iia and the map color is medium blue. This is a deep, poorly drained soil that formed ir loamy colluvium over loam• till. Pie soil occurs in short, narrow drainageways on foot slopes and in long winding drainagelays between }molls and hills. The native vegetation was mainly sedges, grasses and scattered 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. Le Sueur loam: Tic's is a deep, moderately well -drained, loamy soil that formed in cal- careous till. The soil occurs on slight rises and knolls 1 to d feet above the closely intermingled Cordova soils. There arc a few stones and boulders near the surface. The native vegetation was mixed hardwoods and a grass understory. The soil is mapped in only one slope phase in Hennepin County, Le Sucur loam - 1 to 1 percent slooe: The map symbol for this soil is LtB and the m;p color is light green. This soil is nearly level to gently sloping occupying areas on low knolls. There is a perched �.atertable within 3 feet of the surface during wet periods of the ye,ir. Crainage needs to be provided around basement walls. Since the soil is nearly level there is usually little grading required. Soil stren- gth is adequ.-te for residential development. Shrink -swell (volume change) is low to moderate with changes in moist -ire content.
