• EXHIBIT "AA" • ~ <br />significantly more clay, commonly clay looms and light c~ays. These <br />soils could be salvaged and sold for topsoil on the loca~ commercial <br />market for landscaping purposes. This material, when mi ed with <br />equal amounts of sandy loam or loamy sand, would be goodplanting <br />medium for lawns, trees and shrubs. <br />The final grade along the edge of the pond should be 4:7'or flatter. <br />This will provide access for fisherman. Anything steepe~II is <br />generally inaccessa6le. The site is also subject to gro~ind water and <br />will be in a flooded condition after mining. <br />If the post-mining land use is wildlife, I have two further <br />recommendations. In the early stages of mining, preferably by Year <br />5, a visual barrier should be established along the east boundary of <br />the property and along a portion of the north and south Boundaries. <br />This barrier should consist of two rows of trees and shr~lbs. The <br />first raw should be 5 feet from the property boundary ana consist of <br />American Plum(shrubs) on 4 foot centers. The second rowishould be <br />Eastern redcedar(trees) 15 feet from the first row on 12 foot <br />centers. This barrier will provide security for waterfowl on the <br />pond area. <br />With 4:1 slopes around the perimeter of the pond, there ils a very <br />narrow area for emergent aquatic vegetation to become established. <br />This type of vegetation is important for feeding and nesting sites. <br />In the area where the topsoil was stockpiled, west of th shop area, <br />an opportunity exists to create an area of emergent vegetation when <br />the pit is abandoned. When the topsoil is removed from the <br />stoc(ipile, this area could be graded such that the north lend of the <br />stocl<pile is 6 inches above static groundwater and sloping southward <br />at a 1% slope into the pit. The pit edge of this grading could 6e <br />left aC the angle of repose. This grading, when flooded, would <br />provide an area for sedges, rushes, and cattails to become <br />established and could provide feeding and nesting cover for <br />waterfowl. <br />If you have any questions or further reclamation needs, pllease call. <br />SinACerely, <br />'~C l~`9"'ri <br />Gregory L.
