loam. Hard fractured bedrock is at a depth of 26 inches. The available water capacity is low and permeability is moderately rapid. J 1 i Kirksey silt loam, located near the center of the subject site, is moderately well drained and is located on gently sloping upland ridges, in depressions, and around the head of intermittent drainageways. The availabie water capacity is moderate to high and permeability is slow. A perched seasonal high water table is 1.5 to 3 feet during December through March of most years. The surface layer is usually grayish brown slit loam. The subsurface layer is brown silt loam. The subsoil is comprised of brownish yellow slit loam with pale yellow mottles to browntsh yellow silty clay loam with light gray mottles. The underlying material is mottled gray, brownish yellow, and pale yellow channery silt loam. Moderately hard, fractured slate bedrock is at 49 inches. The depth to bedrock is 40 to 60 inches. Misenheimer channery silt loam is loca#ed in patches in the northwest, southwest, and northeast portions of the subject site. This soil is located on broad, nearly level to gently undulating ridges, in depressions, and around the head of intermittent drainageways on uplands and is moderately well drained and shallow. The surface layer usually consists of grayish brown channery silt loam. The subsurface layer is light gray channery silt loam and the subsoil is pale yellow channery silt loam. The underlying material is comprised of mottled brown, gray and yellow channery saprolite. Moderately hard, fractured slate bedrock can be found at 24 inches. The shrink-swell potential and available water capacity is low. Permeability is moderate to moderately rapid. Depth to bedrock is 20 to 40 inches. A perched seasonal high water table is at 1 to~1.5 feet in late winter, early spring, and during wet periods. This soil is droughty during dry periods. Udorthents soils are located around the former quarry area. These soils are found in areas in which the natural soils have been altered by earth moving operations. The areas are borrow pits, gold mines, landfills and quarries. The altered soils are dominantly foamy and have varying underlying material and slopes. Bedrock: The subject site is in the Charlotte Belt of the Piedmont Physiographic Province. According to the Geologic Map of the Charlotte 1° X 2° Quadrangle, North Carolina and South Carolina by Goldsmith, Milton and Horton (1988}, the bedrock at the site is diorite-gabbro. The bedrock is described as massive to weakly foliated gray to dark gray greenish rock composed of plagioclase, horneblende, and pyraxene. 5.4 HISTORICAL USE INFORMATION ON THE SUBJECT SITE Aerial Photographs: Aerial photographs were reviewed in order to examine past land use of the subject site .and the vicinity. The Cabarrus County Soil and Water Conservation Office historic aerial photograph collection covers Cabarrus County. The 1938, 1950, 1956, 1964, 1975, 1987 and 2005 aerial photographs were reviewed on the Cabarrus County G1S website. The 1993 aerial photograph was reviewed at the Cabarrus County Agricultural Extension Office. In the 1938, 1950, 1956, and 1964 aerial photographs, parcel number 5544646749 is predominantly wooded with some open fields in the northeast portion. The parcel appears to be heavily wooded in the 1975 aerial photograph. A dirt road appears along the southern border of the parcel in the 1987 aerial photograph. The 1993 and 2005 aerial photographs appear to be consistent with the 1987 aerial. photograph.
