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 i L__ -A Price Park EEP Project # 291 KCI Associates of North Carolina 2008 - MY06 - Final _ w 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. 1.4 Project History and Background Table 1.

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. - See vegetation data and photos in Appendix A and Current Conditions Plan View in Appendix C. The taxonomic standard being used for vegetation identifications is "Flora of the Carolinas, Virginia, Georgia, and surrounding areas by Alan S. Weakley.

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.
