EXECUTIVE SUMMARY/PROJECT ABSTRACT
The Smith and Austin Creeks Stream Restoration Site (Site) is located in northern Wake County,
approximately 1 mile southeast of the Town of Wake Forest adjacent to the Heritage Development and
Golf Course. The restored stream reaches extend upstream from Forestville Road near the intersection of
Forestville Road and Rogers Road (Figure 1). The project is located within the Neuse River Basin in
United States Geological Survey 14-digit Hydrologic Unit and Targeted Local Watershed
03020201070070 (North Carolina Division of Water Quality subbasin 03-04-02).
The primary goals of the project included the following.
1. Establish stable dimension, pattern, and profile along approximately 11,000 linear feet of
Smith and Austin Creeks.
2. Improve aquatic habitat with bed variability and the use of in-stream structures in Smith and
Austin Creeks.
3. Provide a terrestrial wildlife corridor and refuge in an area that is highly developed for
residential and commercial purposes.
4. Establish a forested riparian buffer adjacent to Smith and Austin Creeks.
5. Incorporate this project into a watershed management plan.
Sixteen vegetation plots (10 meters square) were established and permanently monumented. These plots
were surveyed in June and July 2007 for the 2007 (year 5) monitoring season. Based on the number of
stems counted, the average plot density monitored at this Site is greater than 260 stems per acre and is
considered successful. The average plot density has been measured at 870 stems per acre, or 21 stems per
plot for 2007 (year 5) monitoring. The dominant species identified at the Site were green ash (Fraxinus
pennsylvanica), sycamore (Platanus occidentalis), loblolly pine (Pinus taeda), and river birch (Betula
nigra). Each of the sixteen individual vegetation plots were well-above the success criteria with 405 to
2105 planted stems per acre.
No vegetation problem areas were noted during year 5 (2007) monitoring with the exception of mowed
areas near residential houses. Once mowing is ceased these areas are expected to recover naturally. In
addition, Chinese privet (Ligustrum sinense) is scattered within the Site most notably on the right bank of
Smith Creek near its confluence with Austin Creek, the upper reaches of Smith Creek, and the left bank
along the upper reaches of Austin Creek near the golf course. The Site is characterized by planted
seedlings exhibiting various degrees of vigor. Overall, vigor was noted as good or excellent.
Twenty-three permanent cross-sections were established after construction was completed for the as-built
mitigation plan. Longitudinal profiles were measured after construction and were scheduled to be
completed in year 1 (2003), year 3 (2005), and year 5 (2007) for a total of four measurements. Five 600-
foot reaches were measured for the year 5 (2007) monitoring season. Channel substrate is not expected to
coarsen over time and is not monitored for success at this Site.
As a whole, the majority of Site riffle cross-sections have decreased in cross-sectional area. This may
result from various factors including beaver activity, high sediment loads, and/or stream adjustments
towards a stable, vegetated channel. Width-depth ratios were similar to previous years with slightly
elevated values in Austin Reach 3. This may result from sediment deposition in a stable, low shear stress
reach with good vegetation establishment; width-depth values are expected to lower as the banks continue
to colonize with vegetation and capture sediment. Pools and associated point bars have remained
relatively stable. Longitudinal profile data indicate that riffle and run slopes have decreased while pool
and glide slopes are slightly elevated; however, this is expected due to high sediment loads. In addition,

facet slopes were measured during an extended period of drought, which affected slope measurement
values. Facet slopes are expected to return to typical values once normal rainfall resumes with a slight
increase in slope for riffles and runs, and a slight decrease in slope for pools and glides.
The as-built channel geometry compares favorably with the emulated, stable E/C stream type stream
reaches as set forth in the detailed mitigation plan and construction plans. The current monitoring has
demonstrated dimension, pattern, and profile were stable over the course of the five-year monitoring
period.
Approximately 80.3 percent or 8525 linear feet of onsite reaches are characterized by moderate
BEHI/NBS indicating that stream reaches are relatively stable, exhibiting low erosion rates
(approximately 294.5 tons per year). Site BEHI/NBS values indicate a successful stream restoration
project, particularly when the project location is considered; the project is located within a developing,
urbanized watershed that is targeted for restoration (Targeted Local Watershed 03020201070070). In
addition, erosion rates have decreased significantly over the last year primarily as the result of vegetation
establishment increasing the percentage of surface protection along stream banks throughout the Site.
Vegetation establishment is expected to increase as the Site ages; however, the lack of erosive flows in
late summer and fall may have been beneficial and contributed to the increased establishment of
vegetation along Site stream banks during year 5 (2007).
Several problem areas noted in previous annual monitoring reports were no longer present. During the
current site assessment several areas of bank erosion, mid-point bars, and reduced structure
integrity/failure were identified. Stream problem areas are relatively infrequent within the Site and are
considered minor in respect to the Site location within an urban, developing watershed; upstream
watershed development; and the channel size. Vegetation establishment has increased over the five-year
monitoring period most notably in year 5 (2007) and most problem areas are expected to stabilize over
time with further vegetation establishment. Areas of significant erosion are almost always associated
with a tight radius of curvature or turbulence associated with a root wad. Several areas of erosion are
associated with a compromised structure. In general, stream problems are minor with little to no lateral
erosion or head cutting within the Site. Based on visual inspections and quantitative data over the five-
year monitoring period, the majority of Site stream reaches appear to be migrating toward stable stream
channels. Streams are gaining meanders as the channel continues to deposit point bars, which are
gradually vegetating, creating a more sinuous, stable channel within incised and/or straighter stream
reaches.
Beaver activity has occurred within the Site throughout the five-year monitoring period resulting in
backwater effects from the beaver dams. One dam was identified during the year 5 (2007) monitoring
period on Smith Creek. Recommended proactive maintenance measures include removal of existing
beaver dams and beaver with continued beaver removal, as necessary.
In summary, the restoration site achieved success criteria for vegetation and stream attributes in the Fifth
Monitoring Year (2007) and should be considered successful for the entire five-year monitoring period.

1.0 PROJECT BACKGROUND
1.1 Location and Setting
The Smith and Austin Creeks Stream Restoration Site (Site) is located in northern Wake County,
approximately 1 mile southeast of the Town of Wake Forest adjacent to the Heritage Development and
Golf Course. The restored stream reaches extend upstream from Forestville Road near the intersection of
Forestville Road and Rogers Road (Figure 1). The project is located within the Neuse River Basin in
United States Geological Survey (USGS) 14-digit Hydrologic Unit and Targeted Local Watershed
03020201070070 (North Carolina Division of Water Quality [NCDWQ] subbasin 03-04-02).
Directions to the Site:
From Raleigh, North Carolina
? Travel north on US Highway 1/Capital Boulevard for approximately 9 miles
? Turn right/northeast on US Highway 1-A for approximately 1 mile
? Turn right on Rogers Road for approximately 1 mile (Note: the downstream end of the project is
located northeast of Rogers Road approximately 0.25 mile before the intersection with Forestville
Road/Heritage Lake Road)
? Turn left on Heritage Lake Road approximately 0.5 mile to parking area at soccer fields on left
The Site is located in the Piedmont Physiographic Province, within the Northern Outer Piedmont
ecoregion. The Site is situated within a rapidly developing area on the outskirts of the Town of Wake
Forest. Housing developments and new housing construction surrounds the Site; a golf course is located
at the upstream end of the Site east of Heritage Lake Road, which bisects Austin Creek on the Site, and a
park with soccer fields is located between Smith and Austin Creeks west of Heritage Lake Road.
1.2 Mitigation Structure and Objectives
Historically, the Site was characterized by agricultural land. Site streams were channelized in support of
land uses, resulting in low-sinuosity, incised stream channels. Streambanks and bed features were
unstable throughout the Site due to high shear stress and poor riparian vegetation. The location of the
confluence of the two streams was altered as evidenced by old USGS topographic mapping and United
States Department of Agriculture (USDA) soil survey maps, which show Austin Creek flowing into
Smith Creek approximately 2500 linear feet upstream of the current confluence. A large flood in the
early 1990s caused an avulsion to occur, which rerouted Austin Creek to its current downstream
confluence with Smith Creek. A previous landowner completed the avulsion by excavating a channel and
rerouting Austin Creek to the edge of the valley.
Smith and Austin Creeks were restored by traditional alterations to channel dimension, pattern, and
profile, as outlined in Applied River Morphology (Rosgen 1996) with the establishment of a riparian zone
adjacent to the creeks ranging from 15 to 100 feet in width from the top of bank. Stream implementation
consisted primarily of stream restoration (Priority 1 and Priority 2) where feasible (i.e. the floodplain and
easement widths allowed). Stream enhancement occurred on incised channel reaches where pattern
alterations were not feasible due to a narrow valley and/or existing development. Stream enhancement
consisted of excavation of a new floodplain bench at the bankfull stage and installation of structures to
improve bed features and provide grade control. Structures were installed throughout restoration and
enhancement reaches of Smith and Austin Creeks to maintain the restored channel profile (rock cross-
vanes) and to maintain channel pattern (single vanes). In addition, stream banks were revegetated to
provide bank stabilization.

1.4 Monitoring Plan View
Monitoring activities for the Site, including relevant structures and utilities, project features, specific
project structures, and monitoring features are detailed in Figures 2A through 2H.
Site features including vegetation, stream dimension (cross-sections), stream profile and pattern,
evaluations of bank erosion and near bank stress, and photographic documentation were monitored in
year 5 (2007). Sixteen vegetation plots were installed in year 4 (2006) and permanently monumented
with five-foot metal fence posts driven into each of the four corners of the plot and PVC pipe attached to
the origin for ease in plot location/identification. Twenty-three cross-sections, which were installed after
project construction and permanently monumented with PVC pipe were located and measured for year 5
(2007).
2.0 PROJECT CONDITION AND MONITORING RESULTS
2.1 Vegetation Assessment
Following Site construction three 25-foot by 100-foot vegetation plots were measured for the as-built
mitigation plan. Monitoring plots were changed during the following years with eight 10-meter square
plots measured in year 1 (2003), four 10 meter square plots measured in year 2 (2004), and fifty 10-meter
square plots measured in year 3 (2005). Plots were not permanently marked.
During the 2006 (year 4) monitoring period, sixteen 10-meter by 10-meter plots were established and
permanently marked with five-foot metal fence posts. Sampling was conducted as outlined in the CVS-
EEP Protocol for Recording Vegetation (Lee et al. 2006). The locations of vegetation monitoring plots
were placed to accurately represent the entire Site and are depicted on Figures 2A through 2H.
2.1.1 Soil Data
Soils within the Site are composed of the Chewacla series. Soil data including percentage of clay on the
surface, levels of erosion, and percentage of organic matter are not included in the soil survey for Wake
County. Chewacla series (Aquic Fluventic Dystrochrepts) consists of nearly level, somewhat poorly
drained, moderately permeable soils on floodplains of most streams in Wake County. The depth to the
seasonal high water table is approximately 1.5 feet; the soils are frequently flooded for brief periods.
Natural fertility and the content of organic matter are low (USDA 1970).
2.1.2 Vegetative Problem Areas
A plan view illustrating vegetative problem areas was not included in this report, but was included as part
of the stream problem areas. Two locations on Smith Creek have unwarranted stream crossings near the
soccer fields where vegetation has been removed. The areas should be allowed to revegetate and the Site
should continue to be monitored for similar activity. In addition, Chinese privet (Ligustrum sinense) is
scattered within the Site most notably on the right bank of Smith Creek near its confluence with Austin
Creek, the upper reaches of Smith Creek, and the left bank along the upper reaches of Austin Creek near
the golf course. The Site is characterized by planted seedlings exhibiting various degrees of vigor.
Overall, vigor was noted as good or excellent.
2.1.3 Stem Counts
Sixteen vegetation plots were established and permanently marked as depicted in Figures 2A through 2H.
The plots are 10 meters square and are located randomly within the Site. These plots were surveyed in
June and July 2007 for the 2007 (year 5) monitoring season using the CVS-EEP Protocol for Recording
Vegetation, Version 4.0 (Lee et al. 2006) (http://cvs.bio.unc.edu/methods.htm); results are included in
Table 5. The taxonomic standard for vegetation used for this document was Flora of the Carolinas,
Virginia, Georgia, and Surrounding Areas (Weakley 2007). No reference area was studied; therefore no
comparisons could be made to reference conditions.

Due to the revised monitoring protocol during each year of vegetation surveys, no comparisons of as-built
to the subsequent monitoring years can accurately be made. Therefore, planted species have been based
upon previous annual monitoring reports and percent survival is based on a comparison of as-built (year
0) total stems per acre. The number of "planted" species were based on the experience and judgment of
the monitoring team, and counts for planted species may be influenced by naturally recruited stems.
Based on the number of stems counted, the average plot density monitored at this Site is greater than 260
stems per acre and is considered successful. The average plot density has been measured at 870 stems per
acre, or 21 stems per plot for 2007 (year 5) monitoring. The dominant species identified at the Site were
green ash (Fraxinus pennsylvanica), sycamore (Platanus occidentalis), loblolly pine (Pinus taeda), and
river birch (Betula nigra). Each of the sixteen individual vegetation plots were well-above the success
criteria with 405 to 2105 planted stems per acre.
Shrub diversity was not particularly high within plots; however, various species would be expected to
colonize the Site over time. Species documented within the shrub layer include eastern baccharis
(Baccharis halimifolia), river birch (Betula nigra), and blackberry (Rubus argutus) with tag alder (Aluns
serrulata), black willow (Salix nigra), and sycamore (Platanus occidentalis) along the stream banks.
The herbaceous vegetation is dense in all plots. An inventory of the dominant herbaceous species on the
Site was also taken. It should be noted that species composition is seasonally dependant; surveys for
2007 (year 5) were completed in June and July. Dominant herbaceous species over the Site as a whole
are listed below:
dogfennel (Eupatorium capillifolium)
Johnson grass (Sorghum halepense)
thoroughwort (Eupatorium sp.)
rush species (Juncus spp.)
microstegium (Microstegium vimineum)
sericea lespedeza (Lespedeza cuneata)
goldenrod species (Solidago spp.)
polygonum species (Polygonum spp.)
2.1.4 Vegetation Plot Photos
Photographs were taken at all permanent photo points and are included in Appendix A. The photographs
show that vegetation is generally growing well and consists of a good combination of woody and
herbaceous species.
2.2 Stream Assessment
Twenty-three permanent cross-sections were established after construction was completed for the as-built
mitigation plan. Measurements of each cross-section include points at all breaks in slope including top of
bank, bankfull, and thalweg. Riffle cross-sections have been classified using the Rosgen stream
classification system. Longitudinal profiles were measured after construction and were scheduled to be
completed in year 1 (2003), year 3 (2005), and year 5 (2007) for a total of four measurements.
Longitudinal profile measurements of five 600-foot reaches included thalweg, water surface, bankf ill,
and top of low bank; each should be taken at the head of facets (i.e. riffle, run, pool, and glide) and the
maximum pool depth. Surveys were also used to calculate sinuosity; however, previous monitoring year
surveys were utilized for sinuosity calculations. In addition, channel substrate is not expected to coarsen
over time and is not monitored for success at this Site.
2.2.1 Bankfull Events
Documented bankfull events are included in the table below. Documents for year 0 through year 3 (2002
through 2005) did not provide this data; therefore, data presented prior to year 4 (2006) is limited to
available peak discharge data for a nearby station. Two bankfull events were documented during the year
4 (2006) monitoring period, no known bankfull events are documented thus far for year 5 (2007).

** Reported at USGS Gage Station 0208732885 on Marsh Creek near New Hope. Marsh Creek at this station has a 6.84 square
mile watershed, which is expected to have a bankfull discharge of approximately 357 cfs based on the North Carolina Rural
Piedmont Curves.
2.2.2 Bank Stability Assessments
Detailed Bank Erosion Hazard Index (BEHI) and Near Bank Stress (NBS) assessments were completed
for the year 5 (2007) monitoring report. Results of the assessments are presented in the table below.
BEHI and NBS assessments were not included in monitoring reports prior to year 4 (2006); therefore, no
comparisons between preconstruction or monitoring years prior to year 4 (2006) can be made.
The majority of onsite reaches are characterized by a moderate BEHI and moderate NBS. Reaches that
are characterized by high or extreme BEHI include a section of the downstream preservation reach (Smith
Reach 3) and sections of the upper extents of Smith and Austin Creeks (Smith Reach 1 and Austin Reach
1). These sections of stream are incised, show evidence of prior bank erosion and tree loss with low
rooting densities and some bare soil exposure.
Approximately 80.3 percent of the total length of onsite reaches are characterized by moderate
BEHI/NBS indicating that stream reaches are relatively stable, exhibiting low erosion rates
(approximately 294.5 tons per year). Site BEHI/NBS values indicate a successful stream restoration
project, particularly when the project location is considered; the project is located within a developing,
urbanized watershed that is targeted for restoration (Targeted Local Watershed 03020201070070). In
addition, erosion rates have decreased significantly over the last year primarily as the result of vegetation

establishment increasing the percentage of surface protection along stream banks throughout the Site.
Vegetation establishment is expected to increase as the Site ages; however, the lack of erosive flows in
late summer and fall may have been beneficial and contributed to the increased establishment of
vegetation along Site stream banks during Year 5 (2007).

Stream problem areas are relatively infrequent within the Site and are considered minor in respect to the
Site location within an urban, developing watershed; upstream watershed development; and the channel
size. Vegetation establishment has increased over the five-year monitoring period most notably in year 5
(2007) and most problem areas are expected to stabilize over time with further vegetation establishment.

Areas of significant erosion are almost always associated with a tight radius of curvature or turbulence
associated with a root wad. Several areas of erosion are associated with a compromised structure. In
general, stream problems are minor with little to no lateral erosion or head cutting within the Site. Based
on visual inspections and quantitative data over the five-year monitoring period, the majority of Site
stream reaches appear to be migrating toward more stable stream channels. Streams are gaining meanders
as the channel continues to deposit point bars, which are gradually vegetating, creating a more sinuous,
stable channel within incised and/or straighter stream reaches. Recommended proactive maintenance
measures include beaver removal, as necessary, monitoring for unwarranted vegetation
maintenance/removal, and removal of the irrigation dam.
2.2.4 Stream Fixed Station Photos
Photographs were taken at fixed station photo points and are included in Appendix B. The photographs
show that the stream is generally functioning well with few minor problem areas as discussed above.
2.2.5 Categorical Stream Feature Visual Stability Assessment
Each stream reach was visually inspected during the year 5 (2007) monitoring period using seven feature
categories and various metrics within each category. Assessment features included riffles, pools, thalweg,
meanders, channel bed, structures, and root wads/boulders. Tables for semi-quantitative assessements of
each reach are included in Appendix B (Tables 131-136). The mean percentage of performance for
features within each reach are summarized in the tables below. Data for the as-built and years 1 through 3
(2003-2005) were not provided in previous monitoring reports; therefore, no comparison can be made.

Problem area trends observed during year 5 (2007) monitoring included erosion around root wads with
bank sloughing, potential for future root wad loss, and erosion around structure arms. In addition, the

t 2.2.6 Quantitative Stream Measurements
During the year 5 (2007) monitoring period 23 cross-sections were
I > measured (21 onsite and two just upstream of the Site). Tables for
'A quantitative assessements are included below; these tables include data
from previous years. No cross-sections are located on Smith Reach 3,
which was targeted for stabilization/preservation; therefore, there is no
table summarizing morphological monitoring for this reach. Cross-
section plots for the 21 onsite cross-sections for year 5 (2007)
monitoring are included in Appendix B. Longitudinal profiles were
measured after construction and were scheduled to be completed in
year 1 (2003), year 3 (2005), and year 5 (2007) for a total of four

measurements. Longitudinal profile plots for year 5 (2007) monitoring are included in Appendix B.
Success criteria dictate that there should be little or no change in the as-built cross-sections. If a change
takes place it should be determined if the change is to a more unstable condition (downcutting, erosion) or
to a more stable condition (settling, increase in vegetative diversity, deposition along the banks, decrease
in the width-depth ratio, decrease in cross-sectional area). The as-built longitudinal profile should show
that bed features are neither aggrading nor degrading; however, short-term aggradation/degradation may
occur depending on the peak annual discharge. Bed features should be consistent with those observed in
typical E- and C-type channels. The as-built pattern should not change and the riffle-pool sequence
should remain constant. A significant coarsening of bed materials is not expected due to the sand/gravel
substrate; therefore, bed materials will not be analyzed for stream success.
Permanent cross-sections and longitudinal profiles in the Site are included in Appendix B. Each cross-
section is graphically depicted for as-built through year 5 (2007) for analysis of dimension attributes. As
a whole, the majority of Site riffle cross-sections have decreased in cross-sectional area. This may result
from various factors including beaver activity, high sediment loads, and/or stream adjustments towards a
stable, vegetated channel. Width-depth ratios were similar to previous years with slightly elevated values
in Austin Reach 3. This may result from sediment deposition in a stable, low shear stress reach with good
vegetation establishment; width-depth values are expected to lower as the banks continue to colonize with
vegetation and capture sediment. Pools and associated point bars have remained relatively stable.
Longitudinal profile data indicate that riffle and run slopes have decreased while pool and glide slopes are
slightly elevated; however, this is expected due high sediment loads. In addition, facet slopes were
measured during an extended period of drought, which affected slope measurement values. Facet slopes
are expected to return to typical values once normal rainfall resumes.
The as-built channel geometry compares favorably with the emulated, stable E/C stream type stream
reaches as set forth in the detailed mitigation plan and construction plans. The current monitoring has
demonstrated dimension, pattern, and profile were stable over the course of the five-year monitoring
period.
3.0 FIVE-YEAR MONITORING ASSESSMENT
Results from vegetation surveys exceeded success criteria with 705, 1510, 923, and 870 planted stems per
acre present in years 1, 2, 4, and 5, respectively. Permanent cross-sections and longitudinal profiles
indicate that all reaches classify as E-type or C-type channels and are moving toward more stable reaches.
Stream problem areas are relatively infrequent within the Site and are considered minor in respect to the
Site location within an urban, developing watershed; upstream watershed development; and the channel
size. Vegetation establishment has increased over the five-year monitoring period most notably in year 5
(2007) and most problem areas are expected to stabilize over time with further vegetation establishment.
Areas of significant erosion are almost always associated with a tight radius of curvature, turbulence
associated with a root wad, or runoff from adjacent development. Several areas of erosion are associated
with a compromised structure. In general, stream problems are minor with little to no lateral erosion or
head cutting within the Site. Based on visual inspections and quantitative data over the five-year
monitoring period, the majority of Site stream reaches appear to be migrating toward more stable stream
channels. Streams are gaining meanders as the channel continues to deposit point bars, which are
gradually vegetating, creating a more sinuous, stable channel within incised and/or straighter stream
reaches. Recommended proactive maintenance measures include beaver removal, as necessary,
monitoring for unwarranted vegetation maintenance/removal, and removal of the irrigation dam.
In summary, the restoration site achieved success criteria for vegetation and hydrology for year 5 (2007)
and over the five-year monitoring period.
