1.0 Executive Summary
The Third Fork Creek stream restoration project is located in southwest-central Durham,
North Carolina, in the headwaters of the Third Fork Creek watershed (US Geological
Survey 14-digit Hydrologic Unit Code 03030002060120) within the New Hope Creek
Sub-basin of the Upper Cape Fear River (NC Division of Water Quality Sub-basin 03-06-
05). The project has restored approximately 3,025 linear feet of perennial stream in the
Cape Fear River Basin. Evaluation and design were initiated during the summer of 2002.
Construction was completed in January 2005.
The 2008 Initial Assessment was conducted by RJG&A in May. Subsequent qualitative
evaluations were conducted during September and October 2008. The fourth annual
vegetation monitoring data were collected during July 2008, using EEP's most-recent
monitoring protocol. The fourth annual geomorphologic monitoring data were collected
during September 2008.
Overall, the restoration project appears to have met its design goals. The average live
planted woody stem density (875 live stems per acre) has exceeded the vegetation
success criteria (320 live stems per acre) by 173 percent. According to records provided
by EEP, herbicide treatment was performed on the site in July, August, and October to
reduce the presence of invasive exotic species. Based on our last visit to the site in late
October these treatments appear to have been effective.

2.0 Project Background
2. L Project Goals and Objectives
According to the 2003 Restoration Plan (KCI 2003), the stream restoration project's
goals and objectives are to:
• Restore stable channel morphology that is capable of moving the flows and
sediment provided by its watershed;
• Reduce sediment-related water quality impacts resulting from lateral bank erosion
and bed degradation;
• Improve aquatic habitat diversity through the reestablishment of riffle-pool bed
variability and the use of in-stream structures;
• Restore vegetative riparian buffers utilizing native plant species; and,
• Improve natural aesthetics in an urban park setting.
2.2. Project Structure, Mitigation Type, and Approach
A priority 2 stream restoration approach was used to design and reestablish
approximately 3,025 linear feet of meandering, bankfull channel and a new floodplain
along Third Fork Creek. The project restored riffle-pool sequencing and used cross-vane
and j-hook in-stream structures to provide grade control. The unnamed tributary that
enters from the upper reach's left bank (station 20+33) was incorporated and stabilized
with a grade control structure to match the grade of the restored channel. Coir fiber
matting and live staking were installed/planted to help stabilize the graded stream banks.
Native species were planted in a 50-foot wide buffer on both sides the restored stream.
2.3 Location and Setting
The entire restoration site is contained within Forest Hills Park, which is owned by the
City of Durham. To get to the Third Fork Creek restoration site from NC 147, take exit
12C. At the end of the off-ramp, drive north on Duke Street. At the first light, take a left
on Jackson and then a left on to Vickers. Take Vickers to the intersection with
University Drive (US 151501 Business). Forest Hills Park will be directly in front of you.
Take a right on to University and park in the parking lot across from West Forest Hills
Boulevard (Figure 1).
The upstream boundary of the restoration project is downstream from where Third Fork
Creek emerges from the box culvert under the northern stretch East Forest Hills
Boulevard. The stream restoration extends downstream along the main channel from this
point to the southern edge of the Forest Hills Park. The double box culvert under the
southern stretch of the East Forest Hills Boulevard loop divides the restoration into upper
and lower reaches. An unnamed tributary to Third Fork Creek joins the lower reach on
the downstream end of the culvert. The lower reach therefore has a significantly larger
watershed.

Forest Hills Park is dominated by lawn/open space with relatively little mature canopy
cover (less than 25 percent). A playground and other facilities with impervious cover (e.g
swimming pool, tennis courts, and picnic shelter) are located near the southern portion of
the restoration's upper reach. The surrounding area is highly urbanized. The majority of
the land use is dedicated to residential and commercial development and secondary roads.
Prior to the restoration, both project reaches were incised and had active bed degradation
and channel widening characterized by severe bank erosion.

24. History and Background
KCI Associates of North Carolina designed the Third Fork (Forest Hills Park) stream
restoration. The restoration plan was completed in February 2003 and construction was
completed approximately two years later. As-built data collection occurred in March
2005 and the as-built and year one monitoring reports were submitted in December 2005.
Robert J. Goldstein and Associates collected year two monitoring data and submitted the
Year 2 report in December 2006 and the Year 3 report in October 2007. Year four
monitoring data were collected in July and September 2008.

3.0 Project Conditions and Monitoring Results
RJG&A's 2008 initial assessment was completed on 6 May. Quantitative vegetation and
geomorphologic data were collected between 12 and 20 July. Another qualitative
evaluation was conducted on 29 October 2008.
As was true in 2006 and 2007, structural failure and compromise were recorded in a
number of specific locations. Overall, though, the restoration project appears to be
adequately transporting urban sediment loads and restoring aquatic habitat (i.e. meeting
its design functions/goals).
In our evaluation in May 2008 we noted that several exotic invasive species continued to
have a presence in the restoration area, particularly bankfull benches and floodplain
terraces. However due to herbicidal treatment during the summer and fall the density of
these species was notably reduced. Planted woody stem density remains high.
3.1. Vegetation Assessment
Planted woody vegetation appeared to be successful when qualitatively evaluated during
October 2008. The average live, planted woody stem density for all plots was 22
individuals per plot, including live stakes. According to the Excel file exported from the
CVS/EEP data entry tool, the planted stem density per acre is 875 (excluding live stakes).
This number is down from 905 stems per acre in 2007. This 2008 density exceeds the
required 320 live stems per acre by 173 percent. Stem density is highest for Callicarpa
americana, Fraxinus pennsylvanica, and Platanus occidentalis (Table 5, Appendix A).
Mortality in the vegetation plots remains low (less than 2%).
Monitoring plot photos are also located in Appendix A.
3.1.1. Vegetation Problem Areas
Colonization of bankfull benches and floodplain terraces by invasive woody species and
vines was observed during the spring 2008 assessment, however herbicidal treatment
performed on the site during July, August, and October 2008 appear to have substantially
reduced this problem by the fall of 2008. No thriving colonies of Japanese hops
(Humulus japonicus) or porcelainberry (Ampelopsis brevipedunculata) were observed
during the late October 2008 visit and the only one cluster of princess trees (Paulownia
tomentosa) were observed near vegetation monitoring plot 6, although individual trees
are still scattered throughout the site.
See Table 6, Figure B.1. Current Conditions Plan View, and Vegetation Problem Area
Photos in Appendix A.

3.2.1. Procedural Items
3.2.1.1. Morphometric Criteria
RJG&A personnel qualitatively evaluated the site during May and October 2008. In
September 2008, cross section, pattern, and longitudinal profile data were collected.
Survey data were collected at four cross-sections and along approximately 350 linear feet
of both the upstream and downstream reaches. Photographs were taken at the four cross
sections and at the 14 permanent photo locations that were established by KCI.
3.2.1.2. Hydrologic Criteria
A crest gauge with granulated cork was installed along the right bank at station 33+75 on
13 June 2007. The evaluation of Third Fork Creek in 2008 indicates that at least two
storm events resulted in flows over the designed/built bankfull elevation. The crest gauge
was evaluated on 6 May 2008 and the only cork remaining inside the gauge was stuck
around the cap, indicating that a bankfull storm event had occurred. This conclusion was
supported by evidence of rack and drift lines on the bankfull benches throughout the
restoration. After this evaluation, the gauge was re-filled with approximately five cubic
inches of ground cork. The gauge was again evaluated on 28 October 2008. Again, the
only granulated cork remaining inside the gauge was inside the cap at the top, indicating
that at least one bankfull event had occurred since 6 May. Precipitation data from a
National Weather Service (NWS) COOP station 312515 in Durham County indicates that
bankfull events may have occurred after rainfall events on March 4 (2.00"), April 27-28
(1.84"), July 5 (2.39"), August 28 (4.82"), September 6 (3.98"), and September 26
(2.18") (NC CRONOS 2009).

3.2.3. Problem Areas Table
Overall, the site is maintaining its as-built dimension, pattern, and profile. Several areas
of bank slump/undercut have stabilized and are no longer considered problem areas. Two
areas of bank undercut/scour should be closely monitored. One begins at station 34+10
and the willows on the collapsing bank are impeding water flow; the other is located at
near the bottom of the downstream reach beginning at 38+00 and is new as of this
summer. The former is depicted in photo SP4 and the latter is depicted in photo SP3 in

should continue to be monitored to ensure that they continue to equilibrate over time.

3.2.6. Stability Assessment Table
The visual stability assessment was conducted on October 28, 2008 and the findings are
summarized below. More detailed information can be found in Appendix B5. Low
scores for certain features are due to the accumulation of fine sediment at the site, which
is creating filled-in pools, mid-stream bars, off-center thalwegs, overly-active eroding
meanders, and slumping banks. This fine sediment is both transported from upstream
and off-site into the project area and also enters the stream due to scour and bank slump
in the project area. Secondarily, debris build-up in certain stream segments has
aggravated this problem. Specific examples of these problems are discussed in Section
3.2.3. and Appendices B2 and B3.

IV. Methodology
Monitoring methodologies follow the current EEP-provided templates and guidelines
(Lee et al 2006). Photographs were taken digitally. A Trimble Geo XT handheld
mapping-grade unit was used to collect cross section, vegetation corner, photopoint, and
problem area locations. Additional notations were written on the spring 2008 versions of
the CCPV.
4.1. Stream 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). A South
Total Station and Nikon automatic level were used for collecting all geomorphic data.
Photographs facing downstream were taken at each cross section.
4.2. Vegetation Methodology
Eight representative vegetation survey plots were selected and installed in the upstream
and downstream reaches during September 2006. Where appropriate, the new
monitoring plots were co-located with the first year monitoring plots. All plots measure
100 square meters in area and are either 10 meters by 10 meters, or five meters by 20
meters. Pursuant to the guidelines, the four corners of each plot (e.g. 0,0; 0,10; 10,0; and
10,10; or 0,0; 0,20; 5,0; and 5,20.) marked with 18 inch long one half inch diameter
galvanized steel conduit were relocated in 2008. Within each plot, each planted woody
stem location (x and y) recorded in 2006 was relocated. No mortality was observed.
Level 1 (planted woody stems) and Level 2 (volunteer woody stems) data collection was
performed in all plots, pursuant to the most recent CVS/EEP protocol (Lee et al 2006).
Within each plot, each planted woody stem location (x and y) was recorded, and height
and live stem diameter were recorded for each stem location. All planted stems were
identified with pink flagging. Vegetation was identified using Weakley (Weakley 2007).
Photos were taken of each vegetation plot from the 0,0 corner. Because the dimensions of
the plots installed in 2006 are different than the first annual vegetation monitoring plots,
direct comparison with the first year data is inappropriate.
Tables 1 through 5 in Appendix A contain the data from the vegetation monitoring.
Monitoring plot photos can also be found in Appendix A.
