• EXECUTIVE SUMMARY
i The North Carolina Wetlands Restoration Program identified Bushy Branch in Kentwood Park as
• a restoration project in 2000. The watershed of approximately 1.4 square miles is located within
the USGS 14-digit HUC 03020201090010 and the NCDWQ Sub-basin 03-04-02 of the Neuse
• River Basin. The project restored approximately 1,400 linear feet of channel, 1,070 feet on Bushy
• Branch and 350 feet on an unnamed tributary to Bushy Branch (UT to Bushy Branch). The
restoration was designed to correct various problems with the existing stream corridor including
• unstable channel configuration, poor water quality, minimal bed features, exotic and invasive
i vegetation, and poor stream and riparian habitat. The restoration plan was completed in 2002 and
• called for correcting these problems by stabilizing stream banks, installing in-stream structures,
adjusting stream planform, and replanting the riparian areas with native vegetation. Project
• construction occurred in 2002. This report describes the findings of the fourth year of monitoring
• that took place in 2008.
• The restoration plan called for the removal of all existing problem vegetation along the stream
• banks and within the riparian buffer. The as-built survey found the original planting of native
vegetation to be unsuccessful. To correct the initial failure, a remedial vegetation plan was
• designed and implemented in 2004. Remedial vegetation was planted at a density of 4,840 stems
• per acre in the streamside community and 680 stems per acre in the bottomland hardwood
community. The vegetation monitoring plots were established during the as-built survey. Three
• plots were surveyed and the corners marked with metal conduit for future monitoring. The fourth
• year of monitoring calculated an average of 1,840 planted stems per acre in the streamside
community based on plots 1 and 2 and 1,240 stems per acre in the bottomland hardwood
• community based on plot 3. The use of the park's disc golf course continues to have a detrimental
• effect on the vegetation of UT to Bushy Branch and on the west bank of the upper 250 feet of
Bushy Branch. The damage to the vegetation primarily consists of bare banks and plants being
• trampled due to foot traffic from disc golf players retrieving discs from the stream area. Some
• damage is due to direct impact of the flying discs on the planted vegetation. Microstegium
(Microstegium vimineum) and kudzu (Pueraria montana) are prominent invasive plants that are
• present throughout the site. The kudzu has spread throughout the lower end of the stream and
• should be controlled as soon as possible. The fourth year monitoring found the vegetation
component of the project, excluding these invasive populations, to be on track to meeting success
• criteria.
• The stream assessment completed during the fourth year of monitoring found Bushy Branch to be
• functioning as designed. Channel dimensions based on repeat cross-sections have not changed
• significantly over the monitoring period. There was some localized bank erosion at one point or
another during the monitoring period totaling 8% of the projects bank footage, but the majority of
• these localized, independent instances of bank erosion did not demonstrate advancement over the
• monitoring period. UT to Bushy Branch shows areas of bed degradation with the most significant
problem being the fallen header stone near Station 02+20 that has begun to headcut further
• upstream, stressing the upstream rock sill. There has also been an increase in pedestrian
- footpaths along UT to Bushy Branch, creating more surface area devoid of vegetation and
increasing rill erosion along these paths. Many of the in-stream structures are functioning across
i the project site, though several are experiencing stress evidenced by localized erosion on cross
• vane arms.

1.0 PROJECT BACKGROUND
1.1 Project Objectives
• Installation of in-stream structures to define additional bed features.
• Relocate a section of the stream in order to restore stream pattern.
• Grade severely eroding banks and excavate new bankfull benches.
• Install root wads to promote bank stability.
• Revegetate the adjacent banks to promote the establishment of native plant communities.
1.2 Project Structure, Restoration Type and Approach
A previously incised channel, Bushy Branch, and an unnamed tributary were restored using
channel dimension, pattern, and profile modifications and the establishment of a vegetated
riparian zone adjacent to the stream. Channel profile is maintained through the use of rock cross
vanes. A new channel pattern was constructed through the use of single vanes, root wads, and
vegetation along the channel banks. Due to heavy site use and low planting success, a corrective
vegetation and stream maintenance plan was implemented since initial project completion.
1.3 Location and Setting
Bushy Branch and its unnamed tributary are located in Kentwood Recreational Park within the
city limits of Raleigh, North Carolina. The 1.4-square mile watershed has a park setting
surrounded by urban residential development with little potential for future development.

2.0 PROJECT CONDITIONS AND MONITORING RESULTS

- 2.1 Vegetation Assessment
- After the supplemental planting that took place in 2004, three vegetation monitoring plots were
set up. Plots 1 and 2 were set up directly adjacent to the stream to monitor the plants in the
streamside vegetative community. In monitoring year 04, a density of 1,840 stems/acre was
calculated from these plots. Plot 3 was set up to monitor the bottomland hardwood vegetative
community and calculated a density of 1,240 stems/acre in monitoring year 04. Overall, the
planted vegetation has exhibited good survivability. Most of the vegetative problem areas
- associated with this site are caused by the project's park setting. With a disc golf course adjacent
to the top half of the project, there is heavy foot traffic along the right bank of Bushy Branch from
10+00 to 12+75 and on both sides of UT to Bushy Branch. This foot traffic and the highly
- compacted soils have prevented vegetation from growing on the right bank of Bushy Branch from
the beginning of the project until the confluence with the tributary. Along UT to Bushy Branch
there are many foot paths crossing the easement and there is little vegetation on the terrace
- surrounding the stream. These areas appear to also have been mowed along with the rest of the
park. Towards the end of this summer, a few signs demarcating the easement boundary were
installed, which should prevent these areas from being mowed in the future.
-
There are many invasive exotic species present throughout the Kentwood Park conservation
easement. The most prevalent species include English ivy (Hedera helix), microstegium
- (Microstegium vimineum), mimosa (Albizia julibrissin), kudzu (Pueraria montana), Japanese
• hops (Humulus japonicus) and Japanese honeysuckle (Lonicera japonica). In addition to these
species, Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), and elaeagnus
- (Elaeagnus pungens) have also been observed in the riparian buffer. Due to the urban location of
- the park, there are many sources of invasive species close to the project and complete eradication
of these plants is unlikely. Controlling the invasive species and removing larger individuals
- could help reduce the closest seed sources and decrease competition with the planted native
- species. It is especially important to control the kudzu population, which has already begun to
cover a large portion of the easement and will continue to do so unless treated.

• 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.
2.2. Stream Assessment
The restored reach of Bushy Branch is predominately stable. This site is vertically controlled by
- bedrock and does not have any areas that are experiencing bed degradation or incision. There are
- portions of lateral instability throughout the project, though. In most of the cases the toe of the
streambanks has washed out and many banks are experiencing slight undercut erosion. In a few of
- these cases, the bank vegetation is stabilizing these banks, but there are isolated areas that are
- suffering uncontrolled erosion. The in-stream structures are stable for the most part, but a few of
the cross-vanes have suffered from significant back arm scour. One of the structures has fallen
- apart. The two sets of root wads that were installed have most of the root wad above the stream's
baseflow. This has caused these root wads to begin to rot and they are also suffering from erosion
behind the root wads. On UT to Bushy Creek, a scour hole downstream of a cross vane at Station
02+20 has caused the header boulder of the cross vane to fall into the hole. This headcut has
- begun to move upstream, stressing the structure just upstream of the affected cross vane. There
are two other areas of note on the tributary: one is the small patch of concrete that was poured on

the bank and bed near Station 01+15 and the other is the outlet from a black drain pipe that has
been put into the bank near Station 01+00. These issues are most likely related to the adjacent
playground equipment that was replaced earlier this summer.
A repair assessment is recommended to investigate stabilizing and rebuilding the structure that
has been affected by the headcut on UT to Bushy Creek. If left unstabilized, this vertical
instability could continue to migrate upstream, affecting additional structures. Additional repair
assessment is also recommended at the cross vane that has failed at Station 12+60. There is a
pipe protected by concrete immediately upstream of this structure, which will control vertical
instability, but further bank erosion could continue to take place in this location.
See additional stream assessment and photos in Appendix B and the Current Conditions Plan
View in Appendix C.

Explanation of Probable Causes of Vegetation Mortality
• The Euonymus americana mortality can be attributed to the high foot traffic from the disc
golf course in Vegetation Plot 1. Many paths cross through plot 1 and many plants
(planted and unplanted) have been trampled.
• The decrease in Lindera benzoin in Plot 1 during Monitoring Year 04 could also be
attributed the heavy foot traffic through the plot.
• There is over 100% survival for Quercus phellos in Plot 3. This is due to a miscount
during the as-built stem count.
• There is also over 100% survival for Betula nigra in plots 1 and 2. This is due to either a
miscount during the as-built and first year monitoring stem count or resprouts from the
original plantings that were presumed dead.
