■ <br />Page -2- <br />A brief description of each soil is provided. Map s>Tnbols and colors <br />are provided to facilitate locating the soil types on the detailed <br />soil map provided with this report. <br />Medium <br />Blue <br />Glencoe silty clay loam; <br />The map symbol 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 />loamy colluvium over calcareous loariiy till. The soil is nearly level <br />occupying depressions and drainageways. The native vegetation vras <br />dominantly se^es and wetsite grasses. EKiring wet periods of the <br />year the watertable is within 1 foot of the surface and ponding may <br />occur. 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 />Mediun <br />Blue <br />Hamel loam; <br />The map symbol for this soil is Ha and the map color is medium blue. <br />This is a deep, poorly drained soil that formed in loamy colluvium oyer <br />loamy till. The soil occurs in short, narrow drainageways on foot slopes <br />and in long winding drainageways between knolls and hills. The natwe^ <br />vegetation was mainly sedges, grasses and scattered poplar trees. During <br />wet periods of the year there is a perched watertable within 1 foot of <br />the sinrface and ponding may occur. The high organic matter contCTt in^ <br />the upper soil Jjorizons means the soil has low bearing values. There is <br />a high potential for frost action. <br />Lerdal loam; <br />This is a deep, somewhat poorly drained soil that formed in a cal^reous <br />loamy mantel of till 3 to 20 feet thick. The soil occupies the highest <br />elevations in the county, mainly in the west-central part. Occasional <br />stones and boulders occur near the surface. The native vegetation was <br />mixed hai^woods and a grass understory. The soil is mapped in only one <br />slope phase in Hennepin County. ,, <br />Lerdal loam - 1 to 4 percent slope: <br />The map symbol for this soil is LmB and the map color is light red. This <br />is a nearly level to gently undulating soil that occupies rises and low <br />knolls on the tops of large hills. Since this soil is nearly level little <br />grading is generally required. This soil is wet for short periods with a <br />seasonal watertable at a 3 to S foot depth. Shrink-swell (volume change) <br />is moderate to high with changes in moisture content. The soil is slowly <br />permeable. Soil strength is adequate for residential development.
