EEP Project # 289

Summer 2007 - MY03 - Final
EXECUTIVE SUMMARY
The North Carolina Ecosystem Enhancement Program (EEP) directed 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 the USGS 14-digit HUC 03020201080010 and
the NCDWQ Sub-basin 03-04-02 of the Neuse River Basin. The project restored approximately
4,123 linear feet of channel, 3,828 feet on Hatchet's Grove and 295 feet on Meadow Creek. The
- restoration was designed to correct various problems within the existing stream corridor from
channelization and poor vegetation maintenance practices. Construction was completed in 2004,
and the first and second year monitoring took place in 2005 and 2006, respectively. This report
. describes the findings of the third year monitoring that took place in 2007.
a The riparian buffer zone was planted with sixteen different species of trees and shrubs. The
. bankfull channel area was live staked with three different species. Six vegetation monitoring
. plots were established during the as-built survey. Three buffer plots and three stream bank plots
were established. During the second year of 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 of monitoring and
all six of the plots have been assessed using the new monitoring protocol. The third year of
monitoring counted an average of 740 stems per acre in the riparian buffer. This site does not
- have any exotic vegetation problems. The only vegetation problem areas identified during
. Monitoring Year 03 were poor vegetative coverage on portions of the floodplain and some bare
banks. There are also areas where the riparian buffer has been mowed almost to the streambanks,
including at the beginning of the project where a sewer line easement overlaping the riparian
- buffer has been cleared. These areas are depicted in Appendix C, on the Current Conditions Plan
View. The third year of monitoring found the vegetation component of the project to meet the
vegetation success criterion of 320 stems/acre.
The physical monitoring of the stream's dimension and profile consisted of 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. Previous monitoring reports documented the stream had
i numerous problems with streambank erosion and floodplain scour. The third year monitoring
documented many of these same problems with some previous problems stabilizing and some
worsening. The third year of monitoring found that, due to the drought conditions and fewer
. bankfull events that occurred during 2007, some of the larger areas of bank erosion (Station
14+75) did not worsen during Monitoring Year 03. While parts of the stream have stable
dimensions, streambank erosion is severe enough to warrant timely attention and possible
- maintenance/remediation. There is also evidence of bed degradation and scour along much of the
- stream. This is evident at most of the in-stream structures, where, as illustrated in the profile, the
elevation of the header rock is slightly above the elevation of the streambed upstream of it.
Monitoring Year 03 has found that the stream is generally functioning appropriately, but the
- streambank erosion and bed degradation indicate that the stream is susceptible to change and that
these issues need to be closely monitored.

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 2 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 community, when possible, 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
Hatchet's Grove and Meadow Creek, were incised channels flowing through the Prestonwood
Golf Course that were restored using channel dimension and profile modifications and by
establishing a vegetated riparian zone adjacent to the streams. The channel profile is maintained
through the use of rock cross vanes. The new channel pattern was constructed using 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 forest and agricultural land are sporadically spaced throughout the
watershed. Development pressure will continue to urbanize the watershed, increasing the amount
of impervious area.

During the first monitoring year, the plots were renumbered according to the new vegetation monitoring
protocol set out by the EEP. Of the 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. The third year
vegetation monitoring revealed one missing Quercus laurifolia in Plot 5, the cause of which is unknown. There
was also an increase in Quercus michauxii in Plot 4. These trees were not counted previously because a
bankfull event concealed the trees under sediment and debris. The new trees were surveyed and added to the
plot data. In Plot 1, several trees were cut by the golf course staff, due to the plot being in a play over area.
This play over area appears to be periodically mowed and the woody vegetation is pruned back. The other area

of the buffer that is impacted by the golf course is the riparian buffer along the right bank of Meadow Creek.
Two exotic species, Japanese honeysuckle (Lonicera japonica) and Chinese lespedeza (Lespedeza cuneata),
were found at the site. However, these species were only established sporadically throughout the site.
It should be noted that most of the areas called out as bank erosion on the Current Conditions Plan View are raw
banks and therefore devoid of vegetation. This can be seen in the representative photos for these problem areas.

EEP Project # 289

Summer 2007 - MY03 - Final
The Hatchet's Grove stream has 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. Most of the floodplain scour likely occurred immediately following
construction before vegetation stabilized the floodplain surface. Monitoring Year 03 found that some of these
• areas continue to stabilize as vegetative cover becomes more established. The lower third of the stream has a
stable floodplain with no significant aggradation or degradation noted during the third monitoring year.
- 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 Prestonwood, The placement of the structures in their current location likely had an
adverse impact on the bed stability of the restored channel in these areas. 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
installed 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 their placement, the cross vanes they have been evaluated primarily as grade control measures and stone toe
stabilization, in which case most are functional.
- Fewer areas of streambank erosion were noted in Monitoring Year 03 than in previous years. This is primarily
due to some of the eroding areas becoming stabilized by vegetation. Many of the banks along the main channel
are close to vertical due to previous erosion at the toe of the bank, but there is less overall active erosion than in
- former years.
Two new beaver dams have been built just downstream of the project boundary, 15 feet apart, but still on the
• main channel. The previous beaver dam along the downstream portion of the project is no longer present. The
new beaver dam is ponding the lower portion of the stream, as described in the Current Conditions Plan View.
This beaver dam should be removed to allow normal stream flow.
- Monitoring Year 03 found that the beaver dams along Meadow Creek as documented in Monitoring Year 02
had washed away and were no longer present. As illustrated in the longitudinal profile, Meadow Creek has a
highly unstable streambed that is experiencing continued degradation. The grade of the streambed is somewhat
- controlled by stone sills, which are the only grade control in this stream.
