EXECUTIVE SUMMARY
The North Carolina Ecosystem Enhancement Program (EEP) has facilitated the restoration of
Hatchet's Grove Tributary and an unnamed tributary to Hatchet's Grove (Meadow Creek). Soil
and Environmental Consultants, PA (S&EC) designed the restoration. The watershed of
approximately 3.7 square miles is located within USGS 14-digit HUC 03020201080010 and
NCDWQ Sub-basin 03-04-02 of the Neuse River Basin. The restoration proposed to restore
approximately 4,123 linear feet of channel, 3,828 feet on Hatchet's Grove and 295 feet on
Meadow Creek and 5.3 acres of riparian buffer. The restoration was designed to correct various
problems with the existing stream corridor including channelization and poor vegetation
maintenance practices. The restoration construction was completed in 2004, and first year
monitoring took place in 2005. This report is a description of the findings of the second year
monitoring that took place in 2006.
The riparian buffer zone was planted with 16 different species of trees and shrubs. The bankfull
channel area was live staked with three (3) different species. The vegetation monitoring plots
were established during the as-built survey. Three buffer plots and three stream bank plots were
established. For the second year monitoring, the EEP changed the vegetation monitoring protocol
for this project. The new protocol required that the three stream bank plots be repositioned. The
three new plots were established during the second year monitoring and all six of the plots were
assessed using the new monitoring protocol. The second year monitoring counted an average of
715 stems per acre in the riparian buffer. There were no major problems with exotic / invasive
plants. The only vegetation problem areas were a few patches of bare floodplain and bare banks.
There are also two areas where the riparian buffer has been mowed almost to the streambanks.
These problem areas are depicted in Appendix A, on the Vegetation Problem Area Plan View.
The first year monitoring found the vegetation component of the project to be successful.
The physical monitoring of the stream's dimension and profile consisted of an entire longitudinal
profile of both Hatchet's Grove and Meadow Creek, and two cross-sections on Meadow Creek
and six cross-sections on Hatchet's Grove. The stream assessment completed during the first
year monitoring found the stream to have numerous problems with streambank erosion and
floodplain scour. The second year monitoring documented many of these same problems, with
some previous problems stabilizing and some worsening. While parts of the stream appear to
have stable dimensions, some of the streambank erosion is severe enough to warrant timely
attention and possible maintenance/remediation. The second year monitoring profile shows large
elevation differences from the as-built profile. There is not the same profile-wide elevation
difference in comparison to the first year monitoring profile, but there is a mix of local
aggradation and degradation throughout the profile. These issues are detailed in the following
report and should be closely monitored to determine if corrective actions are warranted.

1.0 PROJECT BACKGROUND
1.1 Project Objectives
• Develop a channel with the appropriate dimension, pattern, and longitudinal profile
utilizing the existing channel condition survey and collected reference reach data as a
guide.
• Improve and create bed form diversity (riffles, runs, pools, and glides).
• Construct a floodplain (bankfull bench) that is accessible at the proposed bankfull
channel elevation (Priority II restoration).
• Ensure channel and stream bank stabilization by integrating grade control structures, root
wads, and native vegetation in conjunction with the eradication or modification of current
grounds maintenance practices.
• Establish a 30-foot native riparian plant communit ,when e from the edge of the
restored reach.
• Integrate existing golf course uses with the proposed restoration plan providing aesthetic
and education values.
1.2 Project Structure, Restoration Type, and Approach
Previously incised channels through the Prestonwood Golf Course, Hatchet's Grove and Meadow
Creek were restored using channel dimension and profile modifications and the establishment of
a vegetated riparian zone adjacent to the streams. Channel profile is maintained through the use
of rock cross vanes. Channel pattern is maintained through the use of single vanes, root wads, and
vegetation along the channel banks.
1.3 Location and Setting
The Prestonwood site is located on a golf course, which is surrounded by apartments and single
family homes. Areas of forested and agricultural land are sporadically spaced throughout the
watershed. Development pressure will continue to urbanize the watershed, increasing the amount
of impervious areas.

The plots have been renumbered according to the new vegetation monitoring protocol. There are now six plots
at the site, three of these are the buffer monitoring plots that were set up for first year monitoring, and three are
new plots that were set up for second year monitoring. For comparison to the first year monitoring report, the
new plot 1 is the same as the first year plot 1, the new plot 3 is the same as the first year plot 2, and the new plot
6 is the same as the first year plot 3. Comparison between monitoring years of these three plots reveals that;
plot 1 has the same number of stems, but the species distribution is different; plot 3 has the same species, but
reveals less than 50% survival; in plot 6 the number of stems was under reported for the first year and the
distribution of species has also changed. The third year of monitoring will provide a better assessment of the
survivability of the vegetation in the plots because of consistency in monitoring and reporting.

The primary problem facing the Hatchet's Grove stream are extended areas of severe bank erosion. While the
specific cause of the bank erosion is unknown, the radius of curvature applied to many of the meanders appears
to be too small for this suburban watershed, causing instability throughout the meanders. These eroded banks
should be closely monitored to determine if corrective actions are warranted. Floodplain conditions along the
stream varied in terms of erosion and deposition. Between stations 10+00 and 28+00 the floodplain shows signs
of aggradation as sand has been deposited on the floodplain during high flow events, see SP5. From station
28+00 to 39+00, the floodplain has eroded creating the bare areas shown in Appendix A2 and areas of
floodplain scour as listed above. Most of the floodplain scour appears to have occurred immediately following
construction, before vegetation stabilized the floodplain surface. These areas were reevaluated during the
second year monitoring and they appear to be stabilizing as vegetation cover becomes more prominent. The
lower third of the stream appears to have a stable floodplain. No significant aggradation or degradation was
noted during the second monitoring year.
The Monitoring Plan View illustrates how the cross vanes are located at the beginning of tangent sections
(heads of riffles) on the stream planform. The action of the cross vane concentrates flow in the center of the
channel and can induce scour. This action helps to maintain pools. The arms also slow water in the near bank
region before redirecting it. The placement of the structures in their current location likely had a
negative/adverse impact on the bed stability of the restored channel in these areas. Hence, the cross vanes on
Hatchet's Grove stream act as grade controls, but also promote the formation of pools where riffles should be
beginning. The cross vane arms do not extend up to the bankfull elevation or 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 the cross vane placement they have been evaluated primarily as grade control measures and stone
toe stabilization, in which case most are functional.
