EXTRACTION AREA B -Since Extraction Area B is located adjacent to a jurisdictional wetland shown as "No Disturbance" on Exhibits C and F, the post mining land use is a constructed wetland mitigation bank. Creating a wetland in this location will enlarge the existing wetland complex in the area providing a broader habitat over timefor a broad diversity of emergent, transitional and upland species of plants, animals, birds and waterfowl. As such, it will restore the site to a land use and topography compatible with the surrounding topography and land uses. The wetland to be created will be 60% palustrine persistent-emergent, that is, it will be a marsh dominated by an array of grass like and broadleaf species of plants that will remain standing until at least the next growing season. Soils are largely fine-grained and expected to remain saturated even through dry seasons. The remainder of the 14.5-acre wetland will be a 27% shrub/scrub wetland -that is, dominated by woody vegetation less than 20 feet tall -and a 13% forested wetland characterized by woody vegetation more than 20 feet tall. Vertically, the created wetland will extend from a border of forested upland vegetation (at approximately 4,598 feet to 4,596 feet of elevation) and transition through a shrublscrub vegetation zone (between 4,595 feet and 4,588 feet) into an extensive persistent-emergent vegetation zone (between 4,588 feet and 4,585 feet) in a series of roughly graded benches and soil surface irregularities. Three islands will be constructed at the persistent-emergent elevations to provide habitat for shrub/scrub species. Exhibit F ,Sheet 4 shows the west border of the created wetland will remain relatively high (at 4,596 - 4,595 feet) to protect the adjacent private property on the west from flooding during high water years. Elevation in the southwest corner will decrease to 4,589 feet -west to east - as it blends with the bank of the north pond in the jurisdictional wetland. As a result, water from the created wetland will drain into the jurisdictional wetland when spring runoff subsides. Prior to gravel extraction within Extraction Area B, the top six to eight inches of topsoil will be removed, scored and protected on site until it is returned to cover the replaced overburden as the planting medium. Overburden will be removed, stockpiled and after mining, used to fill in the pit to the depths required to construct and grade habitats as described above. The fill will be graded to the specifications described below: Slope gradients in the created wetland will be no greater than 3:1 in the forested upland zones and between 3:1 and 6:1 in the shrub/scrub vegetation zones including the shrub/scrub islands. The persistent emergent vegetation zones will consist of rough benches and irregular surfaces with a general grade of 6'.1 or less on the east side of the wetland to about 10:1 on the south-southwest side. The west border of the created wetland will be roughly graded from north to south at no more than a 6:1 grade. The dike between the jurisdictional wetland and created wetland on its southwest side will be taken out and graded down at 3:1 or less to blend into the north pond of the jurisdictional wetland. On the south-central border of the created wetland, the grade from the upland forest at 4,596 feet on the south will decrease on a gradient of no more than 6:1 to 4,593 feet then to no more than 3:1 as the slope blends with the north jurisdictional wetland pond at 4,588 feet. Generally, the entire wetland will be graded gradually downward from southeast to north to west, to south and southwest. The levee will be removed between the created wetlands and the jurisdictional wetland on the southwest side of the created wetland so that the two wetlands will blend and essentially create one wetland. None of the material will be placed in any of the ponds in the jurisdictional wetland. Re-vegetation for Extraction Area B will include planting densities to ensure adequate coverage are determined by formulas derived from the U.S. Environmental Protection Agency, the U.S. Forest Service and the U.S. Fish and Wildl'rfe Service. Using these formulas, 12,632 plants per acre of herbaceous species using a two on center method, and 3,158 per acre of woody species using a four on center method. Eighteen pounds of grass seed mixture (Pure Live Seed) per acre will cover the upland and shrub/scrub vegetation zones including the islands. The following table illustrates the number of acres wmprising each of the created wetland segments, the percentage of thetotal acreage, and the estimated number of plants or pounds of seed mix required to vegetate that segment.
