Glencoesilty clay loam: The map symbol for this soil is Gc and the map color is medium blue. This soil is deep and ver>' poorly drained, 'fhe soil was formed in loamy colluvium over calcareous loamy till, llie soil is nearly level occupying depressions and sluggish drainageways. Site development characteristics are generally unfavorable. The water table is above or near the surface the entire year and the soil has low soil strength. 5. Hamel loam: The map symbol for this soil is 11a and the map color is medium blue. This is a deep, well-drained loam soil that occurs in short, narrow drainageways on foot slopes and in long winding drainageways between knolls and hills. During wet periods of the year there is a perched watertable within 1 foot of the surface. These soils often wet for a good portion of the year. They are also subject to ponding and the upper horizons are high in organic matter content giving than low bearing values. There is also a high potential for frost action to roads or parking lots constructed on these soils. 4. Hayden loam: This is a deep, well-drained loam soil that occurs on gently sloping to very steep slopes, on knolls and hillsides. The soil was strongly influenced by a forest environment in its development. Shale and limestone fragments as well as granitic cobbles and boulders are com mon throughout. Several slope phases are mapped. Each slope phase is discussed separately. a). Hayden loam - 2 to 6 percent slope: The map symbol for this soil is HbB and the map color is medium green. TTiis is a gently undulating soil occupying areas on knolls and hillsides. This soil is well-drained and therefore never saturated although sidehill seepage is not uncommon around base ment walls during rainy seasons or spring thaws. The rolling slopes offer attractive building sites. 5. Lerdal loam: The map symbol for this soil is LmB and the map color is light red. This is a deep, somewhat poorly drained soil that formed in a cal careous loamy mantle of till 3 to 20 feet thick. The soil is nearly level occupying areas low knolls and on the tops of large hills. There is a seasonal groundwater table at a 3-5 foot depth during wet periods and usually persists near these levels over winter after a wet fall. Soil strength is adequate. The infiltration rate of this soil is very slow. Shrink-swell potential is moderate. P « r.' . f > ! : 1
