Project Settine and Background Summary
The Reeds Creek site is a 14.66 -acre tract located southwest of Mooresville in Iredell County on U.S. Highway 21. 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

EEP Recommendation and Conclusion
Overall, the adjacent Reeds Creek stream channel has developed and stabilized after the berm
was lowered. 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.
