1. Executive Summary
The Ellerbe Creek stream restoration a project is located on the Hillandale Golf Course in
Durham, North Carolina just east of the intersection of U.S. 15/501 and Interstate 85 (I-
85). The project has restored 6,279 linear feet of the perennial stream in the Neuse River
Basin (USGS HUC 03020201050010). The drainage area for the site covers
approximately 5,635 acres. Several unnamed tributaries enter Ellerbe Creek upstream of
the restoration site. Project construction began in January 2004 and was completed in
December of the same year. First year monitoring was done in the fall of 2005. Second
year monitoring was completed in November 2006. The third year monitoring was
completed in early July 2007.
RJG&A's initial 2007 qualitative evaluation was conducted on 10 April. Quantitative
vegetation and geomorphologic data were collected between 25 June and 10 July.
Another qualitative evaluation was conducted on 02 October 2007. Vegetation
monitoring was performed, recorded, entered, and analyzed pursuant to the methodology
outlined in the Mitigation Plan and the First Annual Monitoring Report.
The restoration project has met its design goals. No significant geomorphologic changes
have occurred during the third monitoring year. Aquatic and semi-aquatic organisms
have colonized most of the restoration area and the average woody stem density (843 per
• acre) has exceeded the vegetation restoration goal.
II. Project Background
A. Project Objectives
The objectives of the Ellerbe Creek Stream restoration project are to:
1. Establish a new floodplain at a lower elevation and connecting the stream to the
new floodplain;
2. Reduce erosion and sedimentation;
3. Provide wildlife habitat through the creation of a more natural riparian buffer;
4. Improve aquatic habitat with the use of natural material stabilization structures
and a riparian buffer; and
5. Improve water quality within Ellerbe Creek.
B. Project Structure, Restoration Type, and Approach
A Priority 2 stream restoration was used for the most of project's length to establish a
new floodplain, improve sediment transport capability, restore wildlife habitat, and
improve water quality. Some stream enhancement was done in the Croasdaile,
Hillandale, and Albany reaches, where utility rights-of-way were present. The Albany
reach also included preservation. The project involved channel dimension adjustments,
pattern alterations, in-stream structure (root wads, rock vanes, and woody debris)

installation to provide grade control and channel stability, and riparian buffer restoration
(woody vegetation planting and stock exclusion).
The areas where site constraints related to the golf course and utility rights-of-way are
detailed in the As-Built Report.

C. Location and Setting
The Ellerbe Creek restoration is located in the City of Durham on the Hillandale Golf
Course. The golf course and restoration area are located approximately 1,500 feet east of
the I-851U.S. 15/501 intersection, on the east and west sides of Hillandale Road. To
access the site from I-85, travel south on exit 17a (Hillandale Road). Ellerbe Creek is at
the bottom of the first hill. The restoration site begins where Ellerbe Creek emerges from
a double box culvert under I-85, continues east under Belleview Avenue and Hillandale
Road, and terminates approximately 300 feet west of Albany Street. Sprunt Avenue
parallels most of the site to the south. Indian Trail parallels the Albany reach to the north
(Figure 1). The Croasdaile reach is along an unnamed tributary to Ellerbe Creek that
emerges from a double box culvert under I-85. It is paralleled by Belleview Avenue to
the east.
Maintenance of the immediately surrounding golf course, channel straightening, and the
large amount of impervious surface in the surrounding urban watershed were primarily
responsible for the stream's instability. The golf course had intensively managed the
vegetation adjacent to the stream and only a grass buffer existed along the banks. The
result was an entrenched stream with low sinuosity. The channel was incised four to six
feet and erosion and slumping affected large portions of the banks.

III. Project Conditions and Monitoring Results
RJG&A's initial 2007 qualitative evaluation was conducted in April and the project
appeared to be functioning as designed. Subsequent evaluations in July and October
2006 also revealed relatively complete design compliance, with a few minor exceptions,
detailed below.
A. Vegetation Assessment
Hillsborough Reach
Three vegetation problem areas were observed in the Hillsborough reach during the
second growing season. Two of them are on the slopes between the terrace and the golf
course. They are likely to have resulted from rill and gully erosion in compacted subsoil.
The third, and largest, vegetation problem area involves both rill and gully erosion on the
slopes as well as bare soil on the floodplain which appears to be result of poor growth
medium (i.e. too compact/not enough organic material/nutrients). In addition to the three
large vegetation problem areas, originally identified in the 2006 monitoring, small,
isolated rill and gully areas exist throughout the project that have poor vegetative cover,
as well (Appendix A.1 and A.2).
Replanting, mulching, and installation of erosion control devices (e.g. coir matting) in the
• rill and gully areas is recommended. Although poor soil/conditions in the larger
vegetation problem area has resulted in bare soil and sparse herbaceous cover, the
vegetation monitoring plot (HB-V3) located adjacent to the area contains 22 live, planted
stems (or 890 stems per acre). Because the area is far exceeding the goal of 320 stems
per acre, no remedial work appears to be necessary at this time. These areas should
continue to be closely monitored.
Although one beaverdam was observed, and subsequently removed during the
geomorphological survey by an EEP subcontractor, no evidence of beaver browsing was
observed in this, or any other reach in the project.
Croasdaile Reach
The only vegetation problem area observed in the Croasdaile reach was where the
NCDOT rip-rap spillway crosses the stream buffer. No remedial action is
recommended/possible at this time.
Hillandale Reach
A small rill and gully vegetation problem area was observed on the slope from the golf
coarse in the Hillandale reach, immediately downstream from cross section four. As
described above, this vegetation problem area is likely to be the result of the lack of an
adequate substrate.
. Ellerbe Creek Stream Restoration 2007 Final Monitoring Report
Project #127 Year 3 of 5
RJG&A Page 9
Albany Reach •
Two vegetation problem areas were observed in the Albany Reach. Both are a
combination of rill and gully erosion on the slopes and bare soil on the floodplain, due to
poor/compacted soil. Similar to the Hillsborough Reach, vegetation monitoring plots in
the vicinity of these areas have 21 and 36 live planted stems (850 and 1457 stems per
acre respectively), so no remedial action is recommended at this time.
All Reaches
The average live, planted woody stem density for all plots was 20.8 individuals per plot,
(843 stems per acre). This exceeds the required 320 stems per acre in the third
monitoring year by 263 percent, in spite of the 62.8 percent survival of planted woody
stems (Table VII).
B. Stream Assessment
1. Morphometric Criteria
RJG&A staff evaluated the Ellerbe Creek Stream Restoration site during April, June, and
October 2007. The RJG&A staff collected the third year monitoring quantitative
geomorphological data during July 2007.
As the quantitative data and qualitative evaluations indicate, after the third growing •
season the structure and function of the entire restoration project very closely match the
as built conditions and nearly all structures appear to be functioning as designed.
One high priority structural failure was observed at a cross vane on Ellerbe Creek's right
bank at station 6330 (Appendix B I.3). The vane's downstream-most header rock has
become entirely dislodged from the underlying footer and is in the channel below. From
the header's former location, the downstream bank is eroding severely and slumping into
the creek for approximately 30 more feet. Several low priority areas of scour,
aggradation, and structure undermining were observed at other locations ( Exhibit Table
X, Appendix B1).
One beaverdam was found in the Hillsborough reach and removed by a subcontractor
during data collection. The removal occurred on 2 July 2007 and the results of which can
be seen in the longitudinal profile data (Appendix B.6). Beaver were subsequently
removed from the site.
The most obvious structural difference from monitoring year 2, was the increased number
of aggradation areas, mostly in the form of bars. This may be due to a combination of
high beaver activity in 2006 that trapped a large amount of sediment behind the dams,
followed by the low flow conditions of 2007 that resulted in downcutting through the
remaining sediment, instead of moving sediment though the system. The result appears
to be an increase in the size and number of bars, especially in the Albany reach.
Ellerbe Creek Stream Restoration 2007 Final Monitoring Report

Project #127 Year 3 of 5
RJG&A Page 10
• The lowest portion of the Albany reach continues to be "backwatered", presumably due
to downstream beaver impoundments, resulting in flooded structures and aggregation in
the two downstream-most pools.
Several slopes with rill and gully erosion are still present throughout the site. These will
continue to be evaluated. If erosion continues, organic material and secured stability
matting may need to be remedially installed.
Although construction overflow spillway that serves the I-85 stormwater settling basin
has altered a portion of the Croasdaile Reach's right bank and the dimensions of the
adjacent constructed wetland, it appears to be stable and functioning.
2. Hydrologic Criteria
A crest gauge was installed at this site to document bankf ill events on 13 June 2007. As
of 02 October 2007, at least one bankfull event had occurred. Based on NC CRONOS
data from the 312515 Durham weather station during this time period, a bankfull event
most likely occurred in response to a storm that occurred on 28 July 07, when the highest
amount of precipitation (1.08 in) was recorded. Previous to this, potential occurrence
was based on USGS stream gauge discharge data for Ellerbe Creek near Gorman (USGS
02086849). This gauge is located approximately 10 miles downstream of the restoration
• site and has a drainage area of 21.9 square miles. According to the bankfull regional
curves, a stream with a drainage area of 21.9 square miles would reach a bankfull
discharge at 2,144.5 cubic feet per second (cfs) using the urban piedmont regional curves,
and 819.7 cfs using the rural piedmont regional curve (Doll et al., 2002). Presumably
due to a drought in the area, there have been no bankfull flow events at this USGS stream
gauge in 2007 (Figure 2).
Qualitative evaluation (rack and drift lines, downed herbaceous and woody vegetation on
the floodplain) indicated at least one high flow event between 7 December 2006 and 11
April 2007. It is likely that another bankfull event occurred on 12 April 2007, based on
on-site observation by RJG&A staff, of the water level in the channel being two to three
inches below bankfull and rising.

G Wetland Assessment
As part of the project design, a stormwater wetland and 11 pocket wetlands were created
throughout the Ellerbe Creek floodplain. No monitoring wells were established in
relation to any of these wetlands and EEP did not claim any mitigation credit for them.
By all appearances, all of the wetlands appear to be functioning as designed. The
NCDOT rip-rap stormwater spillway could negatively impact hydrology in the
Croasdaile Reach's constructed wetland.
IV. Methodology
Methods employed were a combination those specified in the Mitigation Plan, the First
Annual Monitoring Report, and standard regulatory guidance and procedures documents.
Stream monitoring data was collected using the techniques described in US ACE Stream
Mitigation Guidelines, US Forest Service's Stream Channel Reference Sites, and Applied
River morphology (USACE, 2003; Harrelson et al., 1994; Rosgen, 1996). Vegetation
data collection followed the methodology described in the Mitigation Plan and the First
Annual Monitoring Report. The taxonomic standard used to identify vegetation is Flora
of the Carolinas, Virginia Georgia, and Surrounding Areas (Weakly, 2007).
