addition, one failed rock structure was observed approx. 100 feet downstream of the
tributary/stormwater pipe.
Vegetation diversity appeared pretty good, although the tree density was lower in a section of stream
upstream from the tributary/stormwater pipe.
Despite the fact that this is only year 1, two species of caddisflies were found in the riffles in the upper
portion of the stream.
Being that this is year 1, my only recommendation would be to try rto do something with the area
below the road culvert, as there is a high level of erosion occurring here.
UT to Bear Swamp Creek - Franklin County. According to the report 10 rock structures are not
performing as intended. However, no instability problems were observed because of this. The stream
appeared stable, with good riffle-pool pattern. Some sediment was observed, apparently from
upstream.
Vegetation was very dense, and although pines were abundant, the riparian zone was densely vegetated,
and I don't think it it worth trying to control the pines.
1 species of caddisfly (several individuals) was found in two riffles on the stream.
I would not recommend any work on this stream at this time, and. this project looks like it would go in
the "Successful" category.
Hope the comments are helpful.

My notes/comments on the sites we looked at Friday.
Smith & Austin Creeks - Wake County Stability problems were noted in a number of locations on both
creeks. Erosion around root wads was observed at several locations on Austin Creek. An area on the
r.r'
north/west side of Austin Creek had fescue lawn to the stream bank and appeared to be maintained, "
possibly by a homeowner. A possible buffer violation was observed on the south/east side of the creek,
where fill material for a residential lot was within Zone 1 of the riparian buffer, and the deck of the
house was within Zone 2 of the buffer. On Smith Creek, areas of scour and bank erosion were
observed, and mid-channel bars were noted.
In the lower portion of the stream, in the golf course, a cross vain appears to have failed, as fabric was
dislodged and one or more rocks appeared to be missing.
Overall, I am concerned about the stability of the streams, particularly upstream from the road (Smith
and Austin Creeks, on either side of the soccer fields).
UT to Billy's Creek - Franklin County. The biggest issue here was the considerable amouts of sediment
in the stream, presumably from the upstream farm field. I am concerned that this will be an annual
event. As a result of the sediment, the channel dimension is obscured. From what I could tell, the
banks appear fairly stable, although a portion of the channel circumvented a vain in the middle portion
of the project, and the stream has become somewhat overwidened with mid-channel bars. The lower
reach of the stream did not have a good riffle-pool pattern, and consisted mostly of pools.
There are some vegetation issues, even though this is only year one. Bare areas are present from when
cattle got into the conservation easement area. Juncus is abundant, and in places, is growing within the
channel, sometimes filling the entire channel. The sediment in the channel is also exacerbating this
situation. I am concerned that during a dry summer, the channel may be completely filled with Juncus
in places, which could result in the channel relocating following periods of heavy rain.
Despite the sediment in the channel and the fact that this is only year 1, three species of caddisflies
were found in the riffles in the upper and middle portions of the stream.
Hopefully, the sediment will flush out and the channel will stabilize. I don't think any remedial actions
are warranted at this time, but some additional planting may be warranted int he sparse areas in the
future, a the Juncus may need to be controlled at some point.
UT to Tar River - Franklin County The stream channel appeared to generally be stable, except for
some erosion/scour in the lower portion of the stream, and a large problem area at the road culvert at
the upstream end of the project. In this area, considerable erosion has occurred, and a large vertical
bank has been carved, which is continually releasing sediment to the stream (mass wasting). In

UT to Bear Swamp Creek Restoration Site
1.0 EXECUTIVE SUMMARY
The Unnamed Tributary to Bear Swamp Creek Stream Mitigation Site (hereafter referred to as the "Site")
was constructed for the North Carolina Ecosystem Enhancement Program (EEP) to provide compensatory
stream mitigation in the Tar/Pamlico River Basin. This stream restoration project is located on an
unnamed tributary to Bear Swamp Creek at the Murphy Hay Farm just north of the Town of Louisburg.
This project involves the permanent exclusion of cattle from the stream, stabilization of eroding stream
banks, installation of cross-vane structures for habitat, and the planting of a forested riparian buffer.
The following report summarizes the monitoring activities that have occurred in the past year (the third
year ofproject monitoring) at the Site. Site construction began and was completed in July 2002. As-built
surveys for the Site were performed in August 2002. First year monitoring was conducted in September
2003, and second year monitoring was performed in 2004. The Site must demonstrate vegetative criteria
success and a stable restored stream channel for a minimum of five years or until the Site is deemed
successful. The following paragraphs summarizes the results of the current year monitoring.
Vegetation Monitoring
Vegetation success criteria for the forested riparian restoration areas is based on a minimum survival of
320 stems per acre of planted species at the end of Year 5. Volunteer woody vegetation will also be
included in the survivability calculations. Based on the third year surveys, the average count of the
surviving planted species is 620 stems per acre. If volunteer species are included, the total number of
stems increases to 8,120 stems per acre.
The Site is meeting the established success criteria for vegetation based on the survival of the planted
species. When volunteer species are included in the calculation, the densities are very high. This is
typical of the early forest successional development process when open fields and pastures go fallow.
Early successional species in abundance on the site include loblolly pine (Pinus taeda), red maple (Acer
[rubrum), and sweet gum (Liquidambar styraciflua). The heavy loblolly pine colonization, in particular, is
becoming a nusisance as they compete with the more desireable species for light and nutrients. Measures
may need to be undertaken in the near future to cull their numbers.
Stream Enhancement Monitoring
Success criteria for the restored stream reach has been established to confirm no significant changes have
occurred to the dimension, pattern, profile, and bed material over the 5-year monitoring period. Location
surveys of the constructed features were conducted to verify the performance of the stream. A total
station survey was used to describe the stream longitudinal profile and five permanent stream cross-
section (3 riffles and 2 pools). A modified Wolman pebble count and assessment of the constructed
features was also undertaken.
Overall, the stream channel bed form is stable. Water surface and bed slopes have changed little from the
as-built conditions. However, many of the grade control structures (rock vanes) in the stream have failed
which has led to low to moderate bed degradation immediately behind these structures. Of the twenty-
four rock vanes that were installed, ten are not performing their intended function. Six vanes have water
piping through or behind the structure. The remaining four have filled-in with sediment and have become
obsolete.
EEP Project No. 27
UT to Bear Swamp Creek Restoration Site
Based on the cross-sections and visual observations, the channel dimensions have not changed
significantly. However, observed features and surveyed cross-section indicate that the channel has
narrowed slightly and is developing a bankfull bench at many locations. The stream was designed as a
B5c (step-pool) stream (Rosgen 1996), which provides a sand bed channel with moderate entrenchment
and a moderate width-depth ratio. The current classification measurements are split, with the current
channel exhibiting the moderate entrenchment characteristic of a B-channel, yet exhibiting a very low
width-depth ratio of an E-channel. During the current survey, bankfull indicators were also found at a
significantly lower elevation than those described by the designer. Caution is advised in interpreting and
comparing past years data. This years morphological data is based on the newly identified bankfull
elevation. Pebble counts show no significant change to the channel substrate.

2.0 PROJECT BACKGROUND
2.1 LOCATION AND SETTING
The Site is located north of Louisburg in Franklin County, NC, immediately south of Dyking Road
(SR 1235) at the Murphy Hay Farm (Figure 1, Appendix A). From Raleigh follow Highway 401 north to
Louisburg. Approximately one mile past the the Highway 561 split in Louisburg take a left onto Dyking
Road. The Murphy Hay Farm will be approximately one mile on your left. The entrance to the stream
restoration area is accessed by several gates through the electric fence. The stream restoration reach
begins approximately 460 feet upstream of the road crossing and ends approximately 775 feet
downstream.
2.2 RESTORATION STRUCTURE AND OBJECTIVES
Approximately 1,400 linear feet of an Unnamed Tributary to Bear Swamp Creek were identified on the
32-acre Murphy Hay Farm. The stream had severely degraded and eroded significantly due to past
vegetation removal and the unrestricted access of cattle. The torrential rain events associated with
Hurricanes Fran and Floyd provided the final impetus for restoration work. The stream originates at a
pond approxiamely 500 feet east of Dyking Road and 1,000 feet east of the project. Land use in the
watershed consists of agriculture, pature, forest, and single-family residential.
The design of the new stream included both Priority II and III stream restoration. The degraded F5 and
G5c stream types were restored to a B5c (Rosgen 1996). Approxiamtely 664 linear feet of new channel
was constructed; and 771 linear feet of stream was stabilized in-place. Approximaley 800 tons of rock
were used to construct 24 rock vanes throughout the reach (Figure 2, Appendix A). The vanes were
designed to improve hyraulic flow and reduce shear stress. The vanes also provided bed stabilization and
improved stream habitat by creating pools. The steep, eroded banks were graded back and expanded to
increase the entrenchment ratio. Root wads were also installed to provide bank protecting and additional
habitat diversity. Approximately 2.4 acres of riparian vegetation was also established along the restored
channel in Zone 1 (inner 30 feet) of the Tar/Pamlico Riparian Buffer. This riparian buffer zone has been
fenced to exclude cattle. Site construction began and was completed in July 2002. Project monitoring
began the next year in September 2003.
The objective of this project is to restore habitat and water quality to the restored reach and the Tar-
Pamlico River Basin as a whole. By stablizing the streambed and banks, the restoration will improve
water quality by reducing the amount of sediment contributed to the watershed. Exclusion of cattle and
establishment of a permanent riparian buffer should further help reduce sediment and nutrient imput. The
newly established riparian buffer will provide shade, thereby reducing water temperatures, and increase
habitat and food for wildlife.
