1.0 EXECUTIVE SUMMARY/PROJECT ABSTRACT
On behalf of the North Carolina Ecosystem Enhancement Program (NCEEP), Mid-
_ Atlantic Mitigation, LLC (MAM) with technical assistance from Environmental Services,
Inc (ESI) restored 4 2 acres of riverme wetlands, enhanced 2 2 acres, an additional 8 26
acres of enhancement and preservation areas not included in the WMU calculation are
present on site Grading of the Reeds Creek Site was completed December 2006 Planting
and seeding of the site were completed in January 2007 Overall, the project will restore,
enhance, and/or preserve approximately 14 66 acres of forested and emergent wetlands
and upland buffer, of which 5 3 will be provided as riverine wetland mitigation units
(WMUs) to the North Carolina Ecosystem Enhancement Program (EEP)
The goals and objectives of the Reeds Creek Wetland Restoration Project (Reeds Project)
are to restore the hydrologic functions, the native vegetation of the degraded and drained
wetlands, flood retention and water quality functions within the Reeds Creek watershed
of the Catawba River Basin (HUC 03050101)
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 Native woody vegetation
has been established in this area Jurisdictional wetlands were preserved in the semi -
permanently impounded area associated with Lake Norman Jurisdictional wetlands were
enhanced and/or restored in the area south of Reeds Creek
2.0 PROJECT BACKGROUND
2.1 LOCATION AND SETTING
The Reeds Project is a 14 66 -acre tract located southwest of Mooresville, Iredell County,
North Carolina off of U S Highway 21, approximately 13 miles northeast of the U S
Highway 21 and Interstate 77 intersection (see Figure 1) The project site is located in
the Catawba River Watershed (USGS 8 -digit Hydrologic Unit 03050101, and NCDWQ
River Basin 03- 08 -32) NCDWQ has assigned Reeds Creek within the project site the
Stream Index Number (SIN) of 11- 104(2) The site is immediately adjacent to Lake
Norman and is characterized by a variable floodplain associated with Reeds Creek The
site is currently owned by Mid - Atlantic Mitigation, LLC with the Conservation Easement
being held by the State of North Carolina
2.2 STRUCTURE AND OBJECTIVES
The goals and objectives of the Reeds Creek Wetland Restoration Project are to restore
the hydrologic functions, the native vegetation of the degraded and drained wetlands,
flood retention and water quality functions within the Reeds Creek watershed of the
Catawba River Basin (HUC 03050101) A Project Location Map is provided in Figure 1
Reeds Creek Wetland Restoration Project 1 Monitoring Year 3 of 5
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 The material was graded
to the surrounding landscape to provide microtopographic complexity and woody
planting zones These areas where the topography was enhanced will create diverse
habitats instead of the monotypical, flat lake fringe area that previously existed Surface
hydrology will be reintroduced to the restoration areas via more frequent overbank
flooding from Reeds Creek Native woody vegetation has been established in this area
Jurisdictional wetlands were preserved in the semi - permanently impounded area
associated with Lake Norman Jurisdictional wetlands were enhanced and /or restored in
the area south of Reeds Creek Minor grading, adjacent to the wettest areas, was done to
f expand the wetland hydrology and create microtopography within the contiguous
floodplam and wetland area
The riparian wetland and buffer vegetation community will transition as the system seeks
its hydrologic and vegetative equilibrium Sediments on site were initially unconsolidated
and mucky with saturation due to Lake Norman water level fluctuations While water
level fluctuations are still anticipated, the areas and duration of inundation can only be
determined through post - construction observation and monitoring It was anticipated that
settling and subsidence would occur throughout the initial growing season, first through
evaporation and then through transpiration as the herbaceous cover (seeded and natural
propagation) established Areas that were not saturated/ponded (i.e fringe areas and/or
microtopographic mounds) were planted with bare root seedlings to establish a
bottomland hardwood riparian wetland community
In order to stabilize the newly constructed wetlands and flood plain areas, both temporary
and permanent grass seed were applied to all restored areas. The types of seeds used
were Leersza oryzoides (Rice Cut grass), Panzcum clandestinum (Deertongue grass),
Panicum virgatum (Switchgrass), Trisacum dactyloides (Gama grass), Juncus effusus
(soft rush) and Secale cereale (Annual rye) Three hardwood planting zones were
established as follows Zone 1 -Swamp Forest Zone (the lowest elevations on site), Zone
2- Bottomland Forest Zone (transitional elevations), and Zone 3 -Levee Forest Zone
(areas associated with the tops of the microtopographic planting mounds) A density of
over 750 stems per acre was planted throughout the project Livestakes were installed in
some of the wetter areas but further livestakmg along Reeds Creek may be necessary as
the new streambank/floodplam area stabilizes with its associated wetlands

3.1.2 Vegetative Problem Areas
At this time, no vegetative problem areas or invasive species issues have been identified
The site has been stabilized and vegetated with native woody and herbaceous species.
1 Black willows colonized the site between Year 2 and 3 at a high rate Currently, based on
the composition of the sample plots, the enhancement areas of the site are approximately
60% black willows, while the restoration areas show only about 4% black willows. These
numbers seem to indicate a black willow monoculture could be forming However, the
�- composition of the on -site preservation areas indicate that while black willow may be the
dominate species it does not out compete or prevent other species from thriving as well
The black willows in the enhancement area will be thinned between Year 3 and 4, but no
aggressive strategies, such as herbicide treatments of willows are proposed at this time
3.1.3 Stem Counts
The prevalent vegetation should consist of macrophytes that typically are adapted for life
in saturated soil conditions These species should have the ability to grow, compete,
reproduce, and persist in anaerobic soil conditions A maximum of 15% nuisance
vegetation in wetland areas with planted and volunteer vegetation will successfully
indicate establishment of native wetland vegetation Study plots show that the
composition and density of vegetation in the restoration areas compares closely to the
reference areas Stem counts of over 320 trees per acre after 3 years, and 260 trees per
acre after 5 years will be considered successful Photos taken at established photo points
should indicate maturation of the riparian vegetation community Photographs will help
to illustrate the health of the planted vegetation and the seventy of the invasive or exotic
species that are found within the site Permanent vegetation sampling plots have been
established at 2 random locations and sample each planting zone Plot A is located in the
restoration area, and Plot B is located in the enhancement area The success of vegetative
plantings will be measured through stems counts These plots will be used to sample
both the riparian buffer and restored wetlands Each plot will cover 100 square meters
for tree counts. During the counts, the health of the vegetation will be noted In
addition to stem counts, the samples will inventory species diversity to allow for
comparison between the reference and restoration wetlands and track the percent cover of
nuisance species The vegetation survey will occur during the growing season.

3.1.4 Vegetation Assessment Summary
Vegetation success will be defined as tree survival to meet 320 stems per acre after 3
years and 260 stems per acre after 5 years inside the permanent vegetation sampling plots
and herbaceous cover evaluated with photos showing 75% coverage, after 5 years
In general, the site was over planted to allow for mortality. The site as a whole shows an
average of 1000 planted stems per acre and demonstrates 65 percent survival of planted
species The community is diverse and rich with healthy volunteers Large numbers of
buttonbush and black willow volunteers are present on site and in plots.
Reeds Creek Wetland Restoration Project 6 Monrtormg Year 3 of 5
The herbaceous cover plant community was monitored in a 1 in by 1 in square at one
corner of each plot Each herbaceous quadrant is at or close to 100% cover with no
invasive species noted Additional data from the vegetation sampling plots is located in
Appendix A
3.2 WETLAND ASSESSMENT
3.2.1 Wetland Criteria Attainment
There are three water level monitoring gages located on the Reeds Creek Project
Gages 1 and 2 are located in the restoration area and Gage 3 is located in the
enhancement area in the same location as the pre - construction gage. There are both
mature forested and emergent areas of preservation which were not included in the WMU
calculations adjacent to the small unnamed tributary entering the site from the southeast
corner and flowing into the cove for the Huntington neighborhood. There is a 4t' gage
located in the preservation/fringe area of the site to be used as an on site reference The
data will be downloaded once a month throughout the monitoring period A USGS rain
gage located on Lake Norman (Gage #35301408052495 CRN -42 Norman Shores) will be
used to monitor the amount of rainfall This will be correlated with the ground water data
4 Lake Norman lake levels will also be monitored if the site becomes inundated from high
lake levels As stated in the Mitigation Plan, jurisdictional hydrology for the site will be
defined as saturation within the upper 12 inches of the surface of the soils for a period of
approximately 24 consecutive days during the growing season (239 days between March
and October) or approximately 10% of the growing season Inundation periods of
between 5 and 10% of the growing season may be acceptable in a year that is on record
for moderate to severe drought. The NC Cooperative Extension Service actually lists the
average growing season for Iredell County as 179 days. Therefore, in a year of average
precipitation hydrological success for the Reeds Creek site will be a minimum of 18 days
Gages 1 through 3 entered the onset of the growing season at jurisdictional levels
and maintained them throughout the spring season The Reference gage (4) has been
' dryer than the site gages, but achieved jurisdictional hydrology in the spring as well. The
reference area is thickly vegetated, including a large stand of mature Black Willows near
the gage and is far removed from the inundation effect of Lake Norman Both of these
factors could affect the hydrology of this gage Graphs showing water levels and
corresponding rainfall data are located in Appendix B.
Based on the gage data for 2009, the site has achieved jurisdictional hydrology for the
third consecutive monitoring year Lake Norman Lake levels were higher in Year 3 than
any previous years The area of inundation located in the center of the site closest to the
leading edge of the lake is a mapped NWI wetlands and is considered on site preservation
and not included in the credit calculations for the site This area has remained inundated
for the better part of this year (2009) to date A table showing the 2008 — 2009 13 month
lake level history is provided in Appendix B

3.2.2 Photo Reference Points
There are eight permanent photo reference points located throughout the Reeds
Project included in this monitoring report Two of the photo reference points are located
in the southwest corner of each vegetation plot All the Photographs will help to illustrate
the health of the planted vegetation and the surface water hydrology (e g. standing water)
The Photo Log is located in Appendix A
4.0 SITE SUCCESS ASSESSMENT SUMMARY
Overall, the adjacent Reeds Creek stream channel has developed and stabilized well 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 junsdictional 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 has 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
The group and the site have continued to receive lots of positive press this year. No more
-_ habitat structures are planned for the site, but the group continues to frequent the site to
look for problems and pick up litter
