EXECUTIVE SUMMARY
The North Carolina Wetlands Restoration Program identified UT to Horsepen Creek in Price Park
in Greensboro, North Carolina as a restoration project in 2000. In the past, this project has been
referred to as UT to Horsepen Creek, Price Park and the Jefferson Pilot stream. Henceforth this
project will be referred to as the Price Park project. The approximately 1.0-square mile watershed
is located within the USGS 8-digit HUC 03020002 in the Upper Cape Fear River Basin. The
project restored 1,436 linear feet of incised, channelized stream to 1,776 feet of sinuous channel.
The restoration was designed to correct various problems with the existing stream corridor
including unstable channel configuration, minimal bed features, and poor stream and riparian
• habitat. The restoration plan was completed in October 2000 and called for correcting these
i problems by stabilizing stream banks, installing in-stream structures, adjusting the stream
planform, and replanting the riparian areas with native vegetation. Project construction occurred
in 2001 with additional maintenance construction occurring in February 2002 when additional
. structures were installed. While 2008 is the seventh year since construction was completed,
monitoring was not conducted at the site in 2006. In 2007 morphological monitoring was
• completed, but a formal monitoring report was not prepared. This report describes the findings of
• the sixth year of monitoring that took place in 2008.
The Price Park vegetation monitoring has utilized three different methods throughout the
monitoring period. The vegetation monitoring was originally conducted utilizing transects that
ran perpendicular to the stream. These were monitored for the baseline conditions and during the
first year of monitoring. The second year of monitoring established five square vegetation plots.
These plots were monitored in the second, third, and fourth years of monitoring. In monitoring
year 05, eight 10x10 meter vegetation monitoring plots were established. Where feasible, the new
plots overlapped the approximate areas of the plots established in monitoring year 02. In
monitoring years 05 and 06, the new plots were monitored utilizing the CVS vegetation
monitoring protocol. In the years since planting, there have been many volunteer stems that have
populated the conservation easement. Differentiating between volunteers and planted trees was
difficult, but best efforts were made to do so. From these monitoring plots, a site average of 202
planted stems/acre was calculated in monitoring year 06. Monitoring year 06 also counted
volunteer stems as part of the Level 2 vegetation monitoring. While the site has substantial buffer
acreage and lateral extent for an urban setting, the planted stem survivorship in year-6 as
determined by the vegetation plots is yielding a stem density of 202 stems/acre, approximately
75% of the 260 stems/acre, year-5 criterion. The site also has a substantial volunteer population
comprised mainly of green ash (Fraxinus pennsylvanica), loblolly pine (Pinus taeda), eastern red
cedar (Juniperus virginiana), and tulip poplar (Lirodendron tulipifera) adding to the stem density
substantially to just over 2,000 stems/acre. The most prolific exotic invasive species at the site is
kudzu (Pueraria montana), which already covers a large part of the easement and should be
controlled as soon as possible.
Previous monitoring of the project channel revealed some significant areas of bank instability.
Observations in monitoring year 6 found many of these same areas of erosion. A total of 7% of
bank footage exhibited some state of erosion during the projects history, but most of these
demonstrated little advancement after their initial appearance. Most of these are described as
moderate, with the exception of a serious instance of outright widening near a failed structure at
station 4+00. Many that were previously demonstrating active erosion have begun to stabilize
with vegetation or have become stable over time as the banks were reshaped. This reshaping
came mainly in the form of bench expansion in most cases, meaning the upper section of bank in
some riffle sections scoured, increasing the area of the bench feature. Some of these areas still
need to re-vegetate. Although some of the structures placement and construction were not ideal
in terms of more recent practice and understanding, 85% within the reach are maintaining full
grade control with a single structure exhibiting outright failure. The placement of some of these
Price Park KC[ Associates of North Carolina
EEP Project # 291 2008 - MY06 - Final
structures has limited some of the intended riffle habitat, while adding more discrete functional
pool features. There has been evidence of degradational stress in between grade control points on
the bed at various times in the projects history, but currently the bed footage exhibiting some Amok
form of degradation is estimated at only 3%. The profile has varied vertically over time with the
bulk of this appearing to represent movement of bedload through the system, although the section
between stations 2+00 and 5+00 appears to have exhibited some downcut after construction. This
however does not appear to have advanced over the last 3-4 years since its initial occurrence
earlier in the projects history and the water surface and bankfull slopes are nearly identical as
measured in 2008 and very close to those measured at the As-built stage. While the site has gone •
through some adjustments after construction, it appears that the site is exhibiting a stabilizing
trend with the continued advancement of the vegetation, although the latter will benefit from the
aforementioned planting augmentation and invasive control. i

1.0 PROJECT BACKGROUND
1.1 Project Objectives
The goals and objectives of this project are as follows:
• Provide a stable stream channel that neither aggrades nor degrades, while maintaining its
dimension, pattern, and profile with the capacity to transport its watershed's water and
sediment load.
• Reconnect the stream with its floodplain.
• Improve aquatic habitat with the use of natural material stabilization structures such as
root wads, rock vanes, woody debris and a riparian buffer.
• Provide wildlife habitat and bank stability through the creation of a riparian zone.
• Incorporate the existing greenway plan into the stream restoration plan.
1.2 Project Structure, Restoration Type and Approach
A previously incised channel, UT to Horsepen Creek, was restored using channel dimension,
pattern, and profile modifications and the establishment of a vegetated riparian zone adjacent to
the stream. The Priority I restoration involved converting the 1,436 ft straightened channel into a
sinuous channel that meanders for a total of 1,776 ft. Cross vanes and root wads were
incorporated for aquatic habitat enhancement and bed and bank stability. A 50-foot riparian
buffer on either side of the stream was planted with native vegetation. In addition, an aerial
sanitary sewer line was re-aligned to be perpendicular to the stream flow and a gas line was
rerouted under the stream channel.
1.3 Location and Setting
The Unnamed Tributary to Horsepen Creek is located in Price Park within the city limits of
Greensboro, North Carolina. The 1.0-square mile watershed has a park setting with Jefferson
Elementary located to the west, Price Park to the east, and Guilford College to the south of the
site. There is moderate potential for future development.

2.0 PROJECT CONDITIONS AND MONITORING RESULTS
lions, 2.1 Vegetation Assessment
The Price Park vegetation monitoring has utilized three different methods throughout the
monitoring period. The vegetation monitoring was originally conducted utilizing transects that
ran perpendicular to the stream. These were monitored for the baseline conditions and during the
- first year monitoring. The second year of monitoring established five square vegetation plots.
. These plots were monitored in the second, third, and fourth years of monitoring. In monitoring
year 05, eight 10x10 meter vegetation monitoring plots were established. Where feasible, the new
. plots overlapped the approximate areas of the plots established in monitoring year 02. In
• monitoring years 05 and 06, the new plots were monitored utilizing the CVS vegetation
monitoring protocol. In the years since planting, there have been many volunteer stems that have
populated the conservation easement. Differentiating between volunteers and planted trees was
• difficult, but best efforts were made to do so. From these monitoring plots, a site average of 202
planted stems/acre was calculated in monitoring year 06. The four plots representing the upper
60% of the project above the Jefferson Club Road bridge yielded an average planted stem density
of 320 stems per acre in monitoring year 6, while the area below this bridge demonstrated planted
stem densities of approximately 80 stems/acre. This zone will benefit from planting augmentation
and possibly a jurisdictional delineation for a wetland feature of some apparent quality for the
- lower 200 feet of the project on stream right. The impacts to the vegetation counts were
concentrated in this area primarily because of the repeated beaver activity. EEP's wildlife control
contractor removed beaver on two occasions and broke the dam at the lower culvert, but remnant
- material was used by beaver that recolonized the site and re-established the dam. EEP has
informed KCI that another removal effort was scheduled for earlier this year. Monitoring year 06
also counted volunteer stems as part of the Level 2 vegetation monitoring. The most numerous
. volunteer species included green ash (Fraxinus pennsylvanica), loblolly pine (Pinus taeda),
eastern red cedar (Juniperus virginiana), and tulip poplar (Liriodendron tulipifera). The data from
the sixth year of monitoring revealed that only two of the eight monitoring plots contained
. enough palnted trees to be consistent with the 260 planted stems/acre vegetation success criterion.
• However, including volunteer trees all but two plots had greater than 260 stems/acre and the site
average is 2,033 total stems/acre.
•
The most prolific of the site's exotic invasive species is kudzu (Pueraria montana), which
already covers a large part of the easement and should be controlled as soon as possible. The
• other invasive species that are present in the project area include: Japanese honeysuckle
• (Lonicera japonica), Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiora),
elaeagnus (Elaegnus sp.), mimosa (Albizia julibrissin), oriental bittersweet (Celastrus
- orbiculatus), Johnson grass (Sorghum halepense), lespedeza (Lespedeza cuneata), and
• microstegium (Microstegium vimineum). It is recommended that a site assessment for replanting
be conducted and that an aggressive invasive species control program be implemented.

2.2. Stream Assessment
Previous monitoring of the project channel revealed some significant areas of bank instability.
Observations in monitoring year 6 found many of these same areas of erosion. A total of 7% of
bank footage exhibited some state of erosion during the projects history, but most of these
demonstrated little advancement after their initial appearance. Most of these are described as
moderate, with the exception of a serious instance of outright widening near a failed structure at
approximately Station 4+00. Many that were previously demonstrating active erosion have
begun to stabilize with vegetation or have become stable over time as the banks were reshaped.
In many cases eroded banks can stabilize over time. This can happen as banks become undercut
and then the eventual slumping deposits the vegetated tops of the banks on the toe of the bank.
The result is a bank with a protected toe and a new, more stable and less steep bank. Raw, eroded
banks can also stabilize over time as vegetation grows on them even without slumping. Both of
these natural methods of bank stabilization are occurring along many banks at the Price Park site.
This is apparent throughout the site where the lower portions of the bank are well vegetated, but
the top half of the bank is unvegetated and in some cases still prone to erosion at higher flows. In
most places, the banks at Price Park are vertical, because the toe of bank has eroded away.
However, in some cases these banks have stabilized. An additional year of monitoring will
indicate whether the currently eroding banks are able to stabilize over time. The bank erosion
areas of immediate concern are the ones that still, seven years after construction, do not have
vegetation established on them. These areas can be seen in the Current Conditions Plan View.
The stream is vertically controlled in some places by the cross vanes that are still functioning and
bedrock. There are some apparent areas of stream bed degradation, but most of these areas are no
longer worsening. While the bed features are present throughout the stream, they are not in a
consistent riffle-pool sequence, but the bed exhibits a more diverse and faceted nature than the as-
built profile exhibits. The beaver dam at the downstream limits of the project stream is
backwatering the lower portion of the stream, which is described in the Current Conditions Plan
View.
The Monitoring Plan View illustrates how the existing cross vanes are located at the beginning of
tangent sections (heads of riffles) on the stream planform. A typical cross vane should
concentrate flow in the center of the channel and induce scour to help maintain pools. The arms
should also slow water in the near bank region before redirecting it. At Price Park the placement
of some of the structures in the lowest extent of meanders combined with short riffles was not
ideal in terms of more recent practice and understanding and this has resulted in the conversion of
some intended riffle habitat into pools. The cross vanes on the project stream act as grade control
structures, but also promote the formation of pools where riffles should be beginning. The
installed cross vane arms do not angle out away from the center boulder. Instead of directing
water away from the banks, the vane arms act as large stone toe bank protection. Because of their
placement, the cross vanes have been evaluated primarily as grade control measures and stone toe
stabilization, in which case most are functional. Root wads, which are the other structures at the
site, are only marginally functional. While they are still providing stream and terrestrial habitat,
many of them are positioned above the streams baseflow and are beginning to rot. Certain
degrading root wads then cause the surrounding stabilizing boulders to become displaced in some
instances. In some places the root material is rotted away entirely and the root wads are hard to
find.
See additional stream assessment and photos in Appendix B and Current Conditions Plan View in
Appendix C.

3.0 METHODOLOGY
The CVS-EEP protocol (http:i/cvs.bio.unc.edu/methods.htm) was used to collect vegetation data from
PricePark this year, the sixth year of monitoring. This methodology was incorporated during the fifth
year of monitoring. The method used before that time was the EEP 2004 Stem Counting Protocol.
