Section 1. Site Background Information
A. Site Location and Watershed Setting
Site Location: Figure I includes a location map and driving directions to both the proposed
restoration reach and the reference reach sites. These sites both lie within the Twin Lakes
Business Park and are located within adjacent catchments within the headwaters to Long Creek.
The connector roads in the Park are now cut by the outerbelt right-of-way, and the two sites must
be accessed from different entrances as indicated in the driving directions noted on Figure 1.
Watershed settin< Figure 2 shows the 1:24,000 USES topographic and hydrographic data
for the vicinity of the Twin Lakes Business Park. On this map, the watershed boundaries have
been delineated for both the proposed restoration reach and the reference reach. Both watersheds
are headwater catchments of Long Creek (Catawba River Basin) and lie within the North
Carolina Piedmont Physiographic Region.
The drainage basin contributing to stream flow at the lower end of the proposed restoration
site is approximately 0.15 square miles. "Three small subcatchments converge on the reach
within the drained tale at the restoration site. The drainage basin contributing to stream flow at
the reference reach is also 0.15 square miles. The proposed restoration reach and reference reach
!.. 7 I" l,_ that have t flow. The perennial 1_)SGS map shows only the pfe-
existing lake at the restoration site with an intermittent blue line extending down stream from the
lake. Visits to the site over the last few years has demonstrated that the main channel feeding the
pond (from the NNE subcatchment) is a perennial stream with persistent year round baseflow.
While the USGS map shows the reference reach as an intermittent stream persistent baseflow
was noted throughout August through November 2005. a period during which there had been
below average precipitation, and for which the regional water table would normally have
reached its annual low level.
B. Summary of Stream Restoration
a. Restoration Goal and 0b]ectihes.
The goals of the proposed restoration activities were to restore original morphologic.
hydrologic and ecologic functions to approximately 437 linear feet of a Rosgen E5/C5 stream
reach in northern Mecklenburg County along an un-named I" order perennial stream in
conjunction with the preservation, enhancement and restoration of approximately 0.6 acres of
bottomland wetlands. The stream and bottomland wetlands are located within the *"Twin Lakes
Business Park" on a common area open space tract held b? the Twin Lakes Park Owners
Association, Inc. The site was formerly a small pond, but due to road widening along US21 in
association with construction of the nearby I-485 Charlotte outerbelt, NCDOT drained the pond
and install a riprap lined ditch to coliect and convey runoff to the new culvert that was placed
under the widened US21 (the latter installed at the sedimenteti-in level of the old pond bottom).
Watershed runoff from approximately 0.15 sq. mi. flowed into the former pond where it was
conveyed along a channel, with more ditch-like characteristic-, than that of a natural stream, to
p. 2

' the outflo,.v culvert (Figure 3 of original plan). In 2006, a restoration plan was submitted and
approved fcr a NW27 permit for stream restoration at the site in conjunction with the formation
of two small ponds to serve as value-added amenities for the o.)en space plan within the business
park. The 2006 plan was not implemented due to construction access limitations that persisted
until the fall of 2008. The original restoration permit expired in April of 2007. Between April of
2007 and Spring of 2009, the vegetation, hydrology and soils in the drained pond bottom
continued to evolve, such that in May of 2009 when it was determined that construction access
could again be gained from the recently completed Hwy 21 corridor, substantial areas of
jurisdictional wetlands formed. Thus, in May and June of 2009, the target restoration area was
assessed t«r,jurisdictional wetlands (see Ridner report, Appendix, 2009 restoration plan).
Due to regulatory requirements, the existence of significant jurisdiction wetlands in the old
drained pond bottom required that any restoration attempted at the site provide for increased
wetland and stream benefits. Thus, the 2009 restoration plan revised the original plan to protect,
enhance and restore additional wetlands at the site as a North Carolina Bottomland Swamp
Forest habitat in conjunction with the stream restoration work. Overall, the revised 2009 plan for
restoration at the site aimed to restore the following water related resources within the old
drained pond bottom:
' a) restore -437 feet of a Is' order perennial stream (rruch of which was a rip rap
ditch with no pools or riffles):
b) preserve -.4 acres of jurisdictional wetlands by incorporating these areas in a
permanent conservation easement;
c) enhance the above 0.4 acres of wetlands by blocking the artificial ditches that
were installed to promote drainage and by installing new plants to provide
diversification to existing grasses and shrubs and promote a robust NC
bottomland swamp forest wetland type habitat;
d) restore an additional 0.2 acres of bottomland as Piedmont Bottomland Swamp
Forest wetland:
e) establish two open water areas in hydraulic equilibriam with floodplain shallow
aquifer and adjacent wetlands (as back water strearl splay, or ox-bow lake type
environments) to augment both aquatic resources at the site and park amenity site
' goals: and
f) establish approximately 6000 square feet of littoral habitat in the shallow 0-3 ft
fringe of open water ponds to promote broad spectrn_un ecological support at the
site.
h. Restoration Schedule: The 2009 restoration plan was submitted in early July of 2009
(SAG 2007-2368-6NJ) and approved shortly thereafter. In the fall and winter of 2009/2010,
designs moved into construction plans and local permitting. Financing and final construction
contracts were approved in the late summer of 2010 and construction commenced in early
September. Grading on the site continued until the early part of November 2010. From
November to March, various aspects of the planting schedule were installed. As-built surveys
were conducted in the spring of 201 1. In May of 2011, the (T icial survey of the conservation
p. 3
11
' areas to be protected by the conservation instrument was completed. At the time of writing of
this as-built report, littoral plaid installation is still outstanding, as these are usually a late spring
early summer installation. Due to the presence of geese in the bonds, it has been decided. that the
littoral zones should be planted in 2 or 3 phases with exclusion fencing. If the first plots are
successfully established, the remaining plots will be installed in 2012. Pond water levels are
being suppressed by 10-12" to allow, the deeper 2' depths o4, the littoral plant zones to adapt
gradually to deepening water conditions over a 30-90 day period. Full pond levels should be re-
established. by late summer.
' Section 2. As-guilt Conditions
A. Fluvial Geomorphology
' The overall morphologic parameters of the restored stream's pattern, dimension, and
profile closely followed the reference reach-based design elements laid forth within the original
60% design documents submitted and approved by the NW27 permit. The basic morphologic
design parameters are laid out in 'Table 3 of the initial plan (included here in Appendix A). The
design initially laid forth in this docurnent was adapted slight]} to accommodate tie-in elevations
and zones of unstable running sand encountered during excavation of the new channel through
the old pond sediment. The spillways for both ponds were shitted to opposing stream banks in
order to minimize areas of potentiall impacts horn future potential maintenance, the placement ofd
a grade control sill at the lower end of both spillways, and to facilitate construction.
a) Pattern Restoration: Figure 3 of Appendix B shows the surveyed constructed pattern as
measured using standard stream morphologic survey methods in the winter of 2011 following
final construction of the stream in early November of 2010. The restored intermittent stream
channel is approximately 485 feet in length and is broken up into approximately 18 riffle
(inflection) areas and 1.8 pool (meander) areas. The restored stream pattern parameters followed
the guidelines laid out in the initial restoration plan f"Table 1, Appendix A). The constructed new
alignment follows the alignment laid forth in the initial restoration plans, selected to avoid and
enhance existing wetlands, and mimic meander belt width, radii of meander curvature, and the
meander wavelengths observed in the reference reach.
b) Dimension Restoration: Figure 4 in Appendix C illustrates the typical cross sections
that have been constructed along the length of the restored stream for both inflection and
meander areas. The surveyed data for these monitoring cross sections are tabulated and provided
in Appendix C. Each monitoring cross section has permanent stakes placed for successive re-
occupation over the 5 years of monitoring. A reasonably consistent bankfull cross section area,
aligned with the parameters established by the reference reach, is maintained throughout the
1 restoration, with exception of the last -100' or so feet that drops the stream into culvert that
crosses under US Highway 21. Here, two floodplain benches were necessary (see Figure 3) to
maintain an appropriate bankfull dimension and floodprone width.
c) Longitudinal Profile Restoration: The constructed longitudinal profile was surveyed
by conventional stream morphologic methods (tape and transit level). The final survey tables of
' p. 4

' the data and a plot of the longitudinal profile (Figure 5) are included in Appendix D. On the plot
of the longitudinal profile, the two primary fluvial habitats, riffles and pools, are separated. At
the upper tie-in, a midway point (at the end of the pond spillways) and at the lower tie-in grade
' control structures were installed. The upper and lower tie-in areas had conventional cross vanes
installed and the midway point had a grade control sill put in. The grade control structures were
' constructed by: 1) over excavation, 2) placement of ABC and nonwoven filter fabric as a
preparatory bed for the grade control tabular stones, 3) laying in both a footer and upper layer of
large tabular rock to bring the stream to its design bed elevations, and 4) chinking voids with
smaller rocks, and then matting and seeding banks for the transition around the structure. Also
for grade control, each of the constructed riffle zone had continuous underplating with nonwoven
filter fabric to inhibit any potential for either `outflanking' or incision over time, and at least 1/3
' of the stone placed had diameters in excess of expected mobility thresholds.
' B. Hydrologic Restoration for Stream and Wetlands
The hydrology of the restoration area has already stabilized. By early March of 2011,
' both ponds were full and in equilibrium with water levels in the upslope wetlands. While the
stream was initially thought to transitional from intermittent to perennial in hydrologic nature, it
is likely to be perennial, as it has flowed continuously since its completion in November. All
adjacent wetlands have had surface or near surface water continuously from late February to the
1 S` of June. The two small areas of floodplain bench grading (along the southeastern perimeter of
' the stream restoration) may, or may not, transition to permanent or seasonal wetlands. Overall,
the creation of low head berms along the fringes between the lower pond and the NW wetland
areas provides a net aerial expansion as well as a temporal increase in the duration of wetland
' hydrologic conditions. In addition, to insure grading did not have a detrimental impact on
existing wetlands, coir fiber log runs were established at the downslope areas to those wetlands
not protected by the low head pond berms. These logs will transition to soil and form permeable
' retardation berms for the existing wetlands. Thus far, the project meets, and in several areas
exceeds, design expectations.
' C. Habitat and Plant Community Restoration
Figure 6 (Appendix E) shows an overview of the restoration area broken down into its
four primary habitat areas. These are the a) riparian banks along the stream corridor, b) the
bottomland 'Piedmont Swamp Forest', floodplain wetlands, c) the surrounding hill slopes which
target a general Piedmont Upland Forest community dominated by native hardwood species, and
d) the aquatic plant community to be established in the 0' to ?' water depths around about 70%
of the perimeters of the two ponds. All habitat communities use native species in comparable
' ecological settings, adapted to local factors of microclimate., soils, and hydrology. The final
installed range or mix of species used in each of these areas is laid forth in Table 5 (Appendix E).
Survivorship of these installed plants is discussed in the monitoring and contingency section that
' follows.
p. 5

' Section 3 Monitoring and Contingency Plans
Monitoring and Contingency plans are provided for each of the three habitat elements of
' this restoration: stream, wetlands, and littoral habitats.
Stream Elements: The proposed stream monitoring for this stream restoration is as follows.
' 1) Preparation and submittal of as-built document providing constructed pattern,
dimension and profile sheets that also show the location of all in stream
' structures, and recommended photo stations. Photo stations are to be set up for
up and down stream tie in points, and at selective meander bends and a photo
should be provided looking both up and down stream at each station.
' 2) Field checks with archiving of photo documentation of creek conditions during
first year of flow following completion of planting program after each significant
storm (0.5 inches of rainfall), or alternatively on a bi-monthly schedule.
' 3) Surveys of longitudinal profile and three representatiN e cross sections for each of
five years following completion of restoration activities along with photographs
from each of the established photo stations.
' Should monitoring reveal problems either in the channel, banks,
or riparian buffer areas
the monitoring agent is to inform property owner/manager of the problem. Property
' owner/manager is to seek appropriate professional advise for remedial action and implement
corrective actions as soon as is practical, but the corrective actions should be undertaken no
' longer than one year following initial notice of the problem. Should a corrective action be
undertaken within the 5th year, or for a problem arising during the 5th year, the monitoring
program is to be extended to provide verification of successful corrective actions for at least one
' bankfull event following corrective actions.
Wetland Monitoring: For these wetlands, monitoring of groundwater levels for five years
' between March 1St and May 30th shall be implemented at a minimum of two stations with an
automated water level recorder recording at a frequency of at least one measurement every 12
hours. Saturated conditions in the upper 12" need to be demonstrated for at least 25 days after
' March 15th. Alternatively, yearly monitoring can be preformed to demonstrate saturated
conditions for 12.5% of the growing season (200 days).
Pond Littoral Habitat Monitoring: The littoral zone will also be under a vegetative
monitoring program. The littoral zone and ponds may require cycles of maintenance, and are
likely to be areas of more active management to deal with accumulated sediment, over
accumulation of organic matter (eutrophication issues), invasive plants or shoreline erosion and
deterioration. Thus monitoring and contingency plans for the littoral zone necessarily
incorporate elements of reasonable management activities that may include the potential of
' remedial work to muck out decaying organic matter, invasive weed beds, and to replant sections
in order to restore optimal aquatic conditions. Details will be provided in the addendum to this
plan once more detailed grading and planting specifications are developed.
¦ Section 4. Conservation Easement
' p. 6
The project includes the creation of a legal instrument that shall prevent disturbance
within the restored habitat areas as defined by an encompassing 2.6 acre conservation area that
extends from the upper stream restoration tie-in down to US Hwy 21. The boundaries of the
conservation area have been professionally surveyed and a copy of the survey is shown in Figure
7. Once the as-built documents have been reviewed, either a 'declaration of restrictions' or
`restrictive covenant' agreement that follows generic models provided by the USACOE will be
signed by the owners and recorded. A final copy of the recorded instrument will be provided
within 30 days of its filing.
Section 5. Outstanding Matters/Contingency Considerations
There are two outstanding matters where the restoration has been modified from the 60%
design documents originally submitted due to site conditions.
1) The littoral planting plan was modified due to the presence of geese on the property,
from planting the entire littoral zone at one time to staging the planting over a two to three year
period in order to improve plant survival rates. The habitat professionals at HARP, Inc.
recommended that the Owners install the required planting plots in a phased approach using
geese exclusion fencing on newly planted areas. Littoral planting will occur on 1/3`d of the
perimeter at one time. It is expected that the geese will use areas outside of the fencing for pond
access and foraging, thereby allowing the littoral plants time to establish roots prior to being
exposed to foraging geese and making it more likely that they will survive. Over a two to three
year period, the entire perimeter will be planted and the success of the planting can be
demonstrated prior to the end of the 5-year monitoring.
This phased approach mitigates the potential significant failure and need for replanting
' that is likely to be experienced if the entire littoral fringe is planted at one time and is exposed to
geese foraging prior to becoming established. It also provides an opportunity to observe and
prepare contingency plans that can reflect and address any identified areas of weakness.
' 2) A maintained access trail has been included in the conservation area surrounding the
ponds (Figure 7). It is felt that this access trail will provide necessary maintenance access. This
' restoration project includes the creation of two ponds for both aesthetic and habitat goals.
Earthen berms are prone to slope gully erosion, breaching by burrowing by various animals, and
tree fall. Spillways may be vulnerable to outflanking erosion during very large storms. Ponds
generally fill in with organic muck and sediment over time. Thus from an engineering
maintenance point of view, access/maintenance areas are necessary to be set aside, or excluded
from the conservation area without conflict with the language of the conservation instrument.
The access for long-term maintenance essentially defined a trail on the property, which
could also serve a dual purpose as a walking trail. The zones of human access within the overall
bounding limits of the conservation area are shown in Figure 7 as an excluded area from the
conservation area, within which a 4' wide gravel path with a 2-foot managed vegetative shoulder
which can be established and maintained. The zone connects or provides access to all the
hydrologic components that may require remediation in the future from either US Hwy 21 or the
Twin Lakes Drive on the east. Future maintenance access from both sides was essential in this
plan, as DOT could prohibit a construction/repair access from US Hwy 21 due to proximity to
