1.0 EXECUTIVE SUMMARY / PROJECT ABSTRACT
In 2008, the North Carolina Ecosystem Enhancement Program (EEP) restored and enhanced a reach of
Ellerbe Creek, an Unnamed Tributary to Ellerbe Creek (UT 3), and stream buffer within Northgate Park
in Durham County, NC. The project also included the creation of two stormwater wetlands with outfalls
to the project streams. The 5.9 mi2 project watershed is located in US Geological Survey Hydrologic Unit
03020201-05-0010 (NC Division of Water Quality Sub-basin 03-04-01) of the Neuse River Basin. This
Hydrologic Unit is within EEP’s Ellerbe Creek Local Watershed Plan (2003) area and is also listed as a
Targeted Local Watershed (TLW) in EEP’s Neuse River Basin Priorities Plan (2010).This project is
within the Falls Lake watershed, a drinking supply reservoir for the City of Raleigh. The drainage area for
the site is urban residential land. The State has a permanent conservation easement of 7.5 acres and the
project is located entirely within Northgate Park, which is a City of Durham public park. The project
stream begins at the pedestrian bridge near the baseball diamond and flows 2,284 linear feet to the culvert
under Acadia Street. The project goals and objectives are listed below.
Project Goals
• Improving water quality.
• Enhancing flood attenuation.
• Restoring aquatic and riparian habitat.
Project Objectives
• Restoring the Project Reach to a stable urban stream channel that will retain its dimension,
pattern, and profile over time, and that is capable of transporting watershed flows and sediment
load efficiently.
• Using Priority II restoration to change Ellerbe Creek from a G5c type stream channel to a E type
channel.
• Enhancing the capacity of the site to mitigate flood flows by improving the connection of the
stream to its floodplain.
• Improving aquatic habitat by establishing a heterogeneous bed morphology with riffle-pool
sequences supported by in-stream structures.
• Restoring the riparian buffer from park grasses and herbaceous vegetation to Piedmont
Bottomland Forest to provide filtration of nutrients and organic matter inputs into the stream, to
improve wildlife habitat, and to provide shade for the stream channel.
• Reducing sediment inputs from localized streambank erosion by re-establishing stream geometry
and by stabilizing and revegetating the stream banks.
• Installing three stormwater wetland best management practices (BMPs) to reduce stormwater
pollutants (namely nitrogen and phosphorus) and improve water quality prior to discharging into
the stream.
Ellerbe Creek is a perennial, third-order stream. Three unnamed tributaries and four stormwater outfalls
enter Ellerbe Creek within the project site. The park setting has scattered large trees, recreational grasses,
and patches of upland forest. The restoration and enhancement designs followed a Priority 2 approach.
There are three distinct reaches: Reaches 1 and 2 on Ellerbe Creek and UT 3. Reach 1 (Station 10+00 to
25+80) is the Enhancement I portion of Ellerbe Creek and Reach 2 (Station 25+80 to 32+69) is
Restoration. UT 3 (Station 100+00 to 101+17) covers all of UT 3, which is restoration. Two stormwater
wetlands were also built as a part of this project. One is upstream of UT 3 and the second is on the
stormwater outfall immediately downstream of UT 3 (Outfall 3).
Construction was completed at the site in December 2008. In March 2009, live stakes were planted along
the stream and the stormwater wetlands were planted. The planting of the riparian buffer was delayed
until November 2009 when the rest of the site was planted with tublings and containerized plants. After
planting, six vegetation plots were installed following the CVS-EEP vegetation monitoring procedure,

five in buffer restoration areas and one in the planted stream riparian zone. This report documents the
baseline vegetation monitoring conditions. The vegetation monitoring success criterion for the planted
stream riparian zone is a density of 320 stems/acre after the third year of monitoring and an allowance for
10% mortality in the fourth and fifth years with a final density of 260 stems/acre. The vegetation
monitoring success criterion for the buffer restoration zone is a density of 320 stems/acre after the fifth
year of monitoring. The site’s average baseline density was 600 stems/acre. All six of the plots had
greater than 404 stems/acre. The first-year vegetation monitoring will be based on the Level 2 CVS-EEP
vegetation monitoring protocol to ensure that all of the volunteers are counted. That monitoring will occur
in 2010. The easement includes a few isolated areas of managed herbaceous zones (as shown in Figure 2)
for public safety sight line considerations and pedestrian trail access. These areas are shown in Figure 2.
Invasive vegetation was present onsite prior to restoration. These invasive species were treated/removed
during construction, but some return is likely and will be monitored/addressed as necessary.
The project as-built survey was conducted in January 2009 and KCI conducted the first-year monitoring
survey in January 2010. The longitudinal profile in Appendix D includes the longitudinal profile data
from both of these surveys. The as-built profile data are limited in that the survey measurements taken
were not annotated in the field and water surface measurements were not taken. As a result, the survey is
not detailed enough to generate profile morphology data. The five detailed cross-sections were installed
after the as-built survey, so there are no baseline dimensional data, but there are first-year dimensional
data. Any changes in these cross-sections will be evident when comparing the monitoring data from year
to year. The first year of monitoring found most of Reach 1 to be stable and functioning as designed. The
portion of Reach 1 upstream of the Lavender St. culvert does not have any areas of significant bank
erosion or bed degradation. After the Lavender St. culvert, the stream does have areas of bank erosion and
bed degradation. All but two of the project’s in-stream structures are functioning without any problems.
These areas have been called out in the Current Condition Plan View (CCPV). As a part of the stream
success criterion, the stream must experience at least two bankfull events, each in separate monitoring
years. The site has experienced multiple bankfull events since construction.
Summary information/data related to the occurrence of items such as beaver or encroachment and
statistics related to performance of various project and monitoring elements can be found in the tables and
figures in the report appendices. Narrative background and supporting information formerly found in
these reports can be found in the mitigation and restoration plan documents available on the EEPs
website. All raw data supporting the tables and figures in the appendices are available upon request.

2.0 SUCCESS CRITERIA
2.1 Dimension
The dimensional data from the yearly cross-sectional survey should show minimal change over
the course of the monitoring period. However, some change is natural and expected, indicating
that the site is becoming more stable. Changes that may indicate destabilizing conditions include
significant widening or deepening of the riffle section or a consistent trend of change over the
course of the monitoring. For a pool cross-section, deepening is frequently a positive change
while consistent filling of the pool may indicate destabilization.
2.2 Pattern and Profile
For the profile, the reach under assessment should not demonstrate any trends in thalweg
aggradation or degradation over any significant continuous portion of its length. The profile
should also demonstrate contrasting bedform diversity against the pre-existing condition.
Bedform distribution, riffle/pool lengths, and slopes will vary, but should do so around design
distributions. The majority of pools should be maintained at greater depths with lower water
surface slopes while riffles should be shallow with steeper water surface slopes. Pattern features
should show little adjustment over the monitoring period.
2.3 Substrate
Substrate measurements should indicate the progression towards, or the maintenance of, the
known distributions from the design phase. While stream projects are designed to transport
bedload in equilibrium and carry overall sediment loads at bankfull, fines can be transported even
at low discharges and upstream instability beyond design projections can also lead to deposition
as storm events recede in areas of energy dissipation such as restoration reaches. This can have
the effect of obscuring bedform and fining of riffles especially in the first few years after the
implementation of a stream project. In many cases subsequent narrowing and reduction of width-
to-depth ratios as a project develops/stabilizes can then increase transport efficiency and return
bedform to intended distributions, but some fining can persist due to upstream disturbance.
2.4 Sediment Transport
Maintenance of sediment transport will be evident by the monitored cross-sections and profile.
These two indicators should show no evidence of any significant trend in aggradation or
degradation throughout the channel.
2.5 Vegetation
Vegetation success is based on the criteria established in the USACE Stream Mitigation
Guidelines (2003) and the requirements for Neuse buffer restoration (2000). For the planted
stream riparian zone that is not part of the Neuse buffer credit the vegetation monitoring results
should have the following planted stem density minimums in the corresponding monitoring years:
320 stems/acre through Year Three, 288 stems/acre in Year Four, and 260 stems/acre in Year
Five. For the vegetation plots in the Neuse Buffer restoration areas, the stem density must average
320 stems/acre in Year Five. If the plots in the Neuse Buffer restoration areas attain densities of
between 260 and 320 stems/acre in Year Five, they may be considered successful for the stream
restoration, but the site may not be creditable for Neuse Buffer restoration.
2.6 Hydrology
A minimum of two bankfull events, occurring in separate years, must be documented within the
monitoring period.

EEP Project # 272 4 2010 - MY00 & MY01
3.0 MONITORING PLAN
3.1 Dimension
Five permanent monitoring cross-sections have been established on the site. One pool cross-
section and two riffle cross-sections were established on Reach 1, and there are two riffle cross-
sections on Reach 2. Permanent monuments of rebar in concrete have been established at each
end of these cross-sections. These cross-sections will be surveyed each year, with measurements
occurring at bankfull, top of bank, edge of water, and other significant breaks in slope.
3.2 Profile
The entire profile of the restored stream will be surveyed each monitoring year. The profile will
be surveyed in detail, documenting the elevations of the thalweg, water surface, and bankfull.
Pool and riffle features will be called out to calculate feature slopes and lengths.
3.3 Pattern
Pattern measurements have been taken for the as-built condition and are documented in this
report. Future pattern measurements will not be taken unless there is evidence that significant
geomorphological adjustments have occurred.
3.4 Visual Assessment
A visual assessment of the stream, easement boundary, and site vegetation will be completed each
year to document any problem areas and to provide an overview of the entire site, as required for
the EEP monitoring report.
3.5 Vegetation
Six vegetation plots were set up and assessed for the baseline vegetation monitoring. Vegetation
data collection must follow the CVS-EEP Protocol for Recording Vegetation (Lee et al. 2006,
http://cvs.bio.unc.edu/methods.htm). The baseline vegetation monitoring was conducted as a
Level 1: Inventory of Planted Stems. Beginning in Year One and continuing throughout the rest
of the monitoring period, the site will be monitored using the Level 2 protocol.
3.6 Digital Photos
Ten permanent photo stations have been established as part of the baseline monitoring. Starting in
the second monitoring year, these photos will be taken in late October / early November, so that
vegetative conditions are similar at the site between monitoring years.
4.0 MAINTENANCE AND CONTINGENCY PLANS
Problem areas at the site will be dealt with based on the severity of the problem and at the discretion of
the EEP. Site maintenance may include reinstallation of coir matting, removal of debris from the channel,
stabilization of bank erosion with protective structures, or adjustments to in-stream structures. All
maintenance activities will be documented in the annual monitoring reports.
5.0 METHODOLOGY
The survey data were collected with a total station instrument, using control coordinates supplied by URS
and the as-built surveyor, Level Cross.
The stationing for the longitudinal profile is based on the thalweg stationing.
The CVS-EEP Level 1 Protocol (http://cvs.bio.unc.edu/methods.htm) was used to collect vegetation data
from Ellerbe Creek this year.
