The site is immediately adjacent to Lake Norman and is characterized by a variable floodplain associated with Reeds Creek. The purpose of this project is to restore the hydrologic functions and native vegetation of the degraded and drained wetlands within the Reeds Creek watershed of the Catawba River Basin (HUC 03050101). The Site consists of the Reeds Creek channel and the adjacent floodplain wetlands. These wetlands were degraded and drained because the lands were being managed as goat pasture and contained man-made berms, spoil piles, and unnatural grade elevations, disrupting normal flow patterns and overbank flooding. This site provided an opportunity to restore and enhance a riverine wetland zone by restoring the primary wetland functions and values associated with nutrient removal and transformation, sediment retention, floodflow attenuation, and wildlife habitat (both aquatic and terrestrial). The existing berms and spoil piles adjacent to Reeds Creek were graded down to a more natural elevation and the other existing fill areas were removed and the material graded to the surrounding landscape to provide topographic complexity. These areas where the topography was enhanced will create diverse habitats instead of the monotypical lake fringe habitat that existed in these areas. Surface hydrology was reintroduced to the restoration areas via more frequent overbank flooding from Reed's Creek. Native woody vegetation was established in this area. The Reeds Creek Wetland Restoration Site offers 5.3 riverine wetland mitigation units (WMUs). Goals and Objectives The goals and objectives of the Reeds Creek Wetland Restoration Site include: • Flood retention and water quality functions; • Restoration of natural flooding hydrology of the site; • Restoration of native, forested wetland plant communities Overall, the project will restore, enhance, and/or preserve approximately 14.66 acres of forested and emergent wetlands and upland buffer, 5.3 of which will be provided as WMUs. Specifically, 4.2 acres of wetland habitat will be restored to generate 4.2 WMUs and 2.2 acres of wetland habitat will be enhanced resulting in 1.1 WMUs. The improvement of overall function for the Reed Creek channel and the adjacent floodplain wetlands is expected.. Success Criteria For the Reed's Creek site, a minimum of 11.75 days (5 percent of the growing season) of consecutive inundation or saturation within 12 inches of the soil surface will achieve the minimum hydrologic success for the site. However, ideal hydrologic success for 12.5 percent of the growing season will require at least 29 consecutive days of inundation or saturation within 12 inches of the soil surface. Vegetative success at the mitigation site will be measured by the survival rate over a five -year monitoring period. Overall survivorship of planted woody species is expected to be at least 320 stems per acre after three years and 260 stems per acre Page 2 of 12 MITIGATION UNIT TOTALS Stream Mitigation Units Restoration Segment /Reach Pre — Construction (acreage /linear feet Mitigation Approach Watershed Acreage As -Built Linear Footage /Acreage Mitigation Ratio Mitigation Units (SMU/WMU) Wetland Units WMU -- 5.3 -- WETLAND -- -- Restoration Area -- R -- 4.2 1.0 4.2 Enhancement Area E -- 2.2 2.0 1.1 TOTAL 5.3 MITIGATION UNIT TOTALS Stream Mitigation Units Riparian Wetland Non - riparian Total Wetland Riparian Buffer Nutrient Offset (SMU) Units Wetland Units WMU -- 5.3 -- 5.3 -- -- Page 3 of 12 _yam r `_. •i.

The herbaceous vegetative cover has also developed a healthy and diverse community. The planted trees and shrubs have done very well and are supplemented by a robust existing buffer community which provides seed source for volunteers well suited to the current site conditions. Ground water gages demonstrate favorable trends and jurisdictional wetland hydrology throughout the entire site. Additionally, a local chapter of the North Carolina Wildlife Federation, the Lake Norman Wildlife Conservationists has taken a special interest in the Reeds Creek project. The group worked with Boy Scouts and other local volunteers to build and install wood duck, barred owl, blue bird, and warbler nesting boxes on the site in 2008. Two bat boxes and constructed basking logs for the turtle population were installed in 2009. The group regularly visits the site to pick up litter and monitor for trespassing and vandalism. EEP recommends closure of the Reeds Creek site for 5.3 Wetland Mitigation Units. Contingencies No contingencies are recommended at this time.
