EXECUTIVE SUMMARY
The 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 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 third year monitoring that took place in 2007.
• 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 third
• year monitoring counted an average of 1,984 stems per acre in the streamside community based
on plots 1 and 2, and 1,255 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 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) is a prominent invasive plant
• documented throughout the site. There are also a few areas where kudzu (Pueraria lobata) is
i present and should be controlled as soon as possible. The third year monitoring found the
vegetation component of the project to be successful excluding these invasive populations.

- The stream assessment completed during the third year of monitoring found Bushy Branch to be
functioning. Channel dimensions have not changed drastically from the as-built conditions with
the exception of some areas of bank erosion and lateral adjustment of the channel. The third year
- monitoring profile shows bed degradation from Station 16+25 to 16+50 in comparison to the as-
built profile. Bed aggradation is also present from Stations 11+10 to 11+60 and 12+50 to 13+00.
UT to Bushy Branch also shows areas of bed aggradation and degradation when the profile is
compared to the as-built profile. The most notable problem on the UT to Bushy Branch is an area
- of bed degradation near Station 02+20. The header stone of the upstream structure has fallen into
the pool and a headcut has begun. Many of the in-stream structures are functioning across the
project site, though several are experiencing stress evidenced by localized erosion on cross vane
- arms. Overall, the most extensive stream problem is the instability of the banks along various
parts of Bushy Branch. These bank erosion issues are detailed in the following report and should
be closely monitored to determine if repairs are warranted.

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 have been implemented since initial project completion.
1.3 Location and Setting
Bushy Branch and an unnamed tributary are located in Kentwood Recreational Park within the
city limits of Raleigh, North Carolina. The 1.33 square mile watershed has a park setting
surrounded by urban residential development with little potential for future development.

Explanation of Probable Causes of Vegetation Mortality
• The Euonymus americana mortality can be attributed to the high foot traffic from the disc
golf course or browsing in Vetation 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 03, could be attributed
the heavy foot traffic through the plot or browsing pressure. The direct cause could not
be determined, because the plant was missing.
• One Cornus amomum and one Sambucus canadensis were not found in Vegetation Plot 2.
As stated in previous reports, this vegetation plot is located on a bankfull bench and is
subject to frequent flooding, which may have caused the plants to become.
• The dead Betula nigra in Plot 2, during Monitoring Year 3, was due to insect damage.
• 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 Nyssa sylvatica and 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 had died back.

Monitoring Year 03 documented fewer problem areas than the previous year's monitoring. Many of the
streambanks that had been eroding in previous years have become stabilized by vegetation, or even if they did
not have vegetation covering them, they did not appear to be actively eroding. Some bed instability was
apparent during the annual stream assessment. This was evident in a few areas where the features had
adjusted their length and appeared to still be undergoing adjustment.
