EXECUTIVE SUMMARY
Wildlands Engineering(Wildlands) restored and enhanced a total of 10,706 linear feet (LF) of stream on
a full-delivery mitigation site in Union County, NC.The project streams consist of Norkett Branch, a third
order stream, two unnamed first order tributaries to Norkett Branch (UT1 and UT2), and two
intermittent tributaries to Norkett Branch (UT2A and UT3). Water quality treatment Best Management
Practices (BMPs)were installed to treat water quality on the non-jurisdictional headwaters of UT3 and
an adjacent ephemeral drainage feature.The project is expected to provide 10,098 stream mitigation
units (SMUs).
The Norkett Branch Stream Mitigation Site (Site) is located in southeastern Union County, NC,
approximately ten miles southeast of the City of Monroe and five miles north of the South Carolina state
line.The Site is located in the Yadkin River Basin eight-digit Cataloging Unit (CU) 03040105 and the 14-
digit Hydrologic Unit Code (HUC) 03040105081020 (Figure 1).This CU was identified as a targeted local
watershed in the 2009 Lower Yadkin-Pee Dee River Basin Restoration Priority(RBRP) plan. This plan
identifies agricultural practices and runoff as the probable major sources of water quality impairment in
the Middle Lanes Creek watershed.The 2008 North Carolina Division of Water Resources' (NCDWR)
Basinwide Water Quality Plan (BWQP) lists turbidity and nutrient concentrations of nitrogen and
phosphorus as specific concerns in the Rocky River watershed portion of the Yadkin-Pee Dee River basin.
Other pollutants of concern cited in this report are fecal coliform bacteria, iron, and copper.The project
reaches flow off-site, directly into Lanes Creek, which is included on the NCDWR 303d list of impaired
streams.The section of Lanes Creek downstream of the Site is listed as impaired due to turbidity
(NCDWR, 2012).The project goals established in the Mitigation Plan (Wildlands, 2013)were completed
with careful consideration of goals and objectives that were described in the RBRP and NCDWR BWQR
and to meet the North Carolina Division of Mitigation Services (DMS) mitigation needs while maximizing
the ecological and water quality uplift within the watershed.
The following project goals were established to address the watershed and project Site stressors:
• Improve aquatic and terrestrial habitat within the riparian corridor and provide habitat
corridor extension from adjacent downstream forested habitat,
• Improve additional water quality aspects within stream channels on Site,
• Decrease sediment inputs to the stream channels and decrease turbidity in receiving Lanes
Creek, and
• Decrease phosphorus, nitrogen, and fecal coliform inputs to the stream channels.
Stream restoration and enhancement, water quality treatment BMP construction, and planting efforts
were completed between December 2013 and April 2014. Baseline as-built monitoring activities were
completed between April and May 2014. A conservation easement is in place on the 31.6 acres of
riparian corridor and stream resources to protect them in perpetuity.
This is the seventh and final monitoring year(MY7) as established in the Mitigation Plan (Wildlands,
2013).The site will be presented to the Interagency Review Team (IRT)for regulatory closeout in 2021.
Overall,the Site has met the required stream, hydrologic, and vegetation success criteria for MY7 except
for the average planted stem height in some vegetation plots. Geomorphically, each restored and
enhanced stream has remained stable with cross-sectional dimensions falling within the range of
parameters for the appropriate Rosgen (1996) stream type. Visual stream assessments indicate channel
beds, banks, and engineered structures are functioning as designed with little to no sign of instability.
The average planted stem density for the Site is 405 stems per acre which exceeds the final density
criteria of 210 stems per acre. A majority(18 of 26) of the vegetation plots meet or exceed the final
average stem height requirement of 10 feet at the end of MY7. Visual vegetative assessments indicate
good vegetative cover across the Site with only isolated spots of invasive plant populations.The Site met

Monitoring Year 7 Annual Report- FINAL

final hydrological success criteria after MY3, and all three of the restored reaches (Norkett Branch, UT1,
and UT2) recorded multiple bankfull events during MY7. Water quality results indicated sporadic
pollutant removal by the stormwater BMPs in MY7 compared to previous monitoring years.

Section 1: PROJECT OVERVIEW
The Site is located in southeastern Union County, NC, approximately ten miles southeast of the City of
Monroe and five miles north of the South Carolina state line.The Site is in the Yadkin River Basin eight-
digit Cataloging Unit (CU) 03040105 and the 14-digit Hydrologic Unit Code (HUC)03040105081020
(Figure 1). The Site is located in the Carolina Slate Belt of the Piedmont physiographic province(USGS,
1998).The project watershed consists primarily of agricultural land, pasture, and forest. A conservation
easement was recorded on 31.6 acres within the seven parcels (Deed Book 06095, Pages 0530-0589).
The Site is located within the North Carolina Division of Water Resources (NCDWR) subbasin 03-07-14.
The project streams consist of Norkett Branch, a third order stream, two unnamed first order tributaries
to Norkett Branch (UT1 and UT2), and two intermittent tributaries to Norkett Branch (UT2A and UT3).
Norkett Branch (DWQ Index No. 13-17-40-8) is the main tributary of the project and is classified as WS-V
waters. Class WS-V waters are protected as water supplies draining to Class WS-IV waters or waters
used by industry to supply drinking water or waters formerly used as water supply, and are protected
for secondary recreation, fishing,wildlife, aquatic life, the maintenance of biotic integrity, and
agriculture.The drainage area for the project Site is 2,034 acres (3.18 sq mi) at the lower end of Norkett
Branch Reach 2.
Mitigation work at the Site included restoration on Norkett Branch, UT1, and UT2. Enhancement II was
implemented on UT2A and UT3. Water quality treatment BMPs were also implemented to treat
agricultural drainage upstream of UT3 and agricultural drainage in the right floodplain of Norkett Branch
Reach 2. All on-site riparian areas were planted with native species. Construction and planting activities
were completed in April 2014. Directions and a map of the Site are provided in Figure 1 and project
components are illustrated in Figure 2.
1.1 Project Goals and Objectives
Prior to construction activities, the streams were routinely maintained to provide drainage for
agricultural purposes. Impacts to the streams included straightening and ditching, eroding banks, and a
lack of stabilizing riparian vegetation.The streams were also used as a water source for cattle in some
areas resulting in over-widened, unstable, and trampled banks. Algal blooms, presumably from
agricultural nutrient loading, were observed during Site visits.Trampled stream banks, over-widened
channels, and banks illustrating signs of instability were a common occurrence throughout the Site.The
alterations of the Site to promote farming resulted in an impairment of the ecological function of Site's
streams. Specific functional losses at the Site included degraded aquatic habitat, altered hydrology, and
the reduction of quality in-stream and riparian wetland habitats, as well as related water quality
benefits.Table 4 in Appendix 1 and Tables 11 a-c in Appendix 4 present the Site's pre-restoration
conditions in detail.
The mitigation project is intended to provide numerous ecological benefits such as pollutant removal
and improved aquatic and terrestrial habitat. Expected improvements to water quality and ecological
processes are outlined below as project goals and objectives.The agricultural stressors and pollutants
have been specifically addressed by the Site design.The major goals of the stream mitigation project are
to provide ecological and water quality enhancements to the Norkett Branch, Lane's Creek, Rocky River
and Yadkin River Basins while creating a functional riparian corridor at the Site level and restoring a
Piedmont Bottomland Forest as described by Schafale and Weakley(1990).These project goals were
established with careful consideration of goals and objectives that were described in the RBRP and to
meet the North Carolina Division of Mitigation Services (DMS) mitigation needs while maximizing the
ecological and water quality uplift within the watershed.
Norkett Branch Stream Mitigation Site
Monitoring Year 7 Annual Report- FINAL 1-1

The following project goals and objectives were established and listed in the Mitigation Plan (Wildlands,
2013)to address the effects listed above:
• Improve aquatic and terrestrial habitat within the riparian corridor and provide habitat corridor
extension from adjacent downstream forested habitat. By restoring appropriate channel cross
section and profile, including riffle and pool sequences, coarse substrate zones for
macroinvertebrates and deep pool habitat for fish. Introduction of large woody debris, rock
structures, brush toe, and native stream bank vegetation to provide additional habitat and cover
for both fish and macroinvertebrates. Adjacent buffer areas will be restored by planting native
vegetation which will provide habitat and forage for terrestrial species.These areas will be
allowed to receive more regular inundating flows, and vernal pools may develop over time
increasing habitat diversity.A watershed approach, restoring riparian corridor functions on
multiple interconnected tributaries as well as treating agricultural drainage from headwater
features with BMPs, will allow for large-scale riparian corridor connectivity.
• Improve additional water quality aspects within stream channels on Site. Riffle/pool sequences
will be restored to provide re-aeration allowing for oxygen levels to be maintained in the
perennial reaches. Creation of deep pool zones will lower temperature, helping to maintain
dissolved oxygen concentrations. Establishment and maintenance of riparian buffers to create
long-term shading of the stream and to minimize thermal heating. Water quality BMPs situated
in the headwaters, upstream of jurisdictional streams, will treat agricultural runoff before it
reaches project streams.
• Decrease sediment inputs to the stream channels and decrease turbidity in receiving Lanes
Creek. Cattle will be fenced out of the riparian corridor, eliminating bank trampling. Sediment
input from eroding stream banks will be reduced by bioengineering and installing in-stream
structures while creating a stable channel form using geomorphic design principles. Sediment
from off-site sources will be captured by deposition on restored floodplain areas where native
vegetation will slow overland flow velocities. By allowing for more overbank flooding and by
increasing channel roughness, in-channel velocities can be reduced.This will lower bank shear
stress and decrease bank erosion.
• Decrease phosphorus, nitrogen, and fecal coliform inputs to the stream channels. Nitrogen-and
phosphorus-laden chemical fertilizers, pesticides, and cattle waste will be decreased by
buffering adjacent agricultural operations from the restored channels. Cattle will be fenced out
to eliminate in-channel fecal pollution. Off-site nutrient input will be absorbed on-site by
filtering flood flows through restored floodplain areas,water quality BMPs, and vernal pools
positioned to treat concentrated overland flow. Flood flows will be allowed to disperse through
native vegetation across the reconnected floodplain. Increased surface water residency time will
provide contact treatment time and groundwater recharge potential.

Monitoring Year 7 Annual Report- FINAL 1-2

1.2 Monitoring Year 7 Data Assessment
Annual monitoring was conducted between March and November 2020 to assess the condition of the
project. The stream restoration success criteria for the Site follows the approved success criteria
presented in the Mitigation Plan (Wildlands, 2013).
1.2.1 Vegetative Assessment
A total of 26 vegetation plots were established during the baseline monitoring within the project
easement area using standard 10-meter by 10-meter vegetation monitoring plots. Plots were randomly
established within planted portions of the stream restoration and enhancement areas to capture the
heterogeneity of the designed vegetative communities. The plot corners were marked and are
recoverable either through field identification or with the use of a GPS unit. Reference photographs
were taken at the plot origin looking diagonally across the plot to the opposite corner to capture the
same reference photograph locations as the as-built. The final vegetative success criteria will be the
survival of 210 planted stems per acre in the riparian corridor along restored and enhanced reaches at
the end of the seventh year of monitoring (MY7). Planted vegetation must average 10 feet in height in
each plot by MY7.
The MY7 vegetation survey completed in September and October 2020 resulted in 23 of 26 vegetation
plots meeting the year seven success criteria (210 stems per acre). Three vegetation plots (plots 5, 7,
and 10) have planted individual stem densities of 202 stems per acre; however, vegetation plot 10 stem
density increases to 243 stems/acre with inclusion of volunteers. Overall,the Site has an average
planted stem density of 405 stems per acre which exceeds the year seven success criteria. The average
woody stem density of the Site with volunteers is 601 stems per acre. In MY7, planted stems heights for
the Site averaged 12.5 feet which is a 42% increase in height compared to the MY6 stem height average
of 8.8 feet. Eight plots have average stem heights below the final success criteria of 10 feet. The average
stem height in these plots range from 4.6 to 8.8 feet. Most planted woody stems (90%) within
vegetation plots had a vigor rating of 3 or more.
In February 2015 during MY2, supplemental planting added 6,000 stems (37%of the MY1 stem total) on
reaches east of Philadelphia Church Road. The supplemental planting was in response to low stem vigor
of many plots and high bare root mortality between the as-built and MY1 which was attributed to dry
site conditions, lack of soil fertility, scour flows shortly after installation, insects, and disease. An
additional supplemental planting in MY5 added 400 containerized trees (3%of the MY5 stem total) on
portions of Norkett Branch and UT1 in response to low stem density. In MY6, 50 containerized tree (less
than 1% of the MY6 stem total) were added in areas of poor woody growth documented in MYS. Some
of the monitoring plots showed an increase in planted stem densities in MY2 and MY5 because of the
supplemental planting.
Refer to Appendix 2 for vegetation plot photographs, the Current Condition Plan View (CCPV) maps, and
the vegetation condition assessment table and Appendix 3 for vegetation summary tables.
1.2.2 Vegetation Problem Areas
The planted riparian buffer continues to develop along project streams with minimal vegetative problem
areas. In the late winter/early spring of MY4, several areas previously identified as "Bare/Poor
Herbaceous Cover" were addressed through a combination of reseeding and the installation of
hugelkultur(hugel) beds. The hugel beds provided additional organic matter and aided in moisture
retention to encourage herbaceous and woody vegetation growth. Hugel bed installation involved the
excavation of small floodplain trenches that were backfilled with organic matter, covered in a mixture of
soil and brush, and planted with live whips, live stakes and seeded. The live stakes and whips were
planted to anchor the beds. As the woody species established, they helped diffuse the energy of out of
bank events and trap additional organic matter. During MY6 and MY7, several hugel beds have slightly
Norkett Branch Stream Mitigation Site
Monitoring Year 7 Annual Report- FINAL 1-3

subsided which is likely a result of backfilled organic matter breaking down and/or compacting. Planted
whips and lives stakes on the hugel beds were also not as vibrant as previous years however hugel beds
have served their purpose as bare areas have filled in and woody vegetation continues to establish.
Pockets of invasive species including cattail (Typha latifolia), Chinaberry tree (Melia azedarach), Chinese
privet(Ligustrum sinense),Japanese honeysuckle(Lonicera japonica), and parrot feather(Myriophyllum
aquaticum)were observed during MY7; however, most are localized pockets, too small to map (less
than 1,000 square feet) and are not impacting planted vegetation. Mapped invasives account for less
than 1% of the easement acreage. Parrot feather populations located along Norkett Branch Reaches 1
and 2 were treated with glyphosate between May and July 2020; however,this aquatic invasive may
persist until the streambed becomes fully shaded. Areas of dense groundsel tree (Baccharis halimifolia),
an aggressive coastal plain native evergreen shrub, were mechanically and chemically treated during
MY4.This species is not typically considered a species of high concern for DMS-required monitoring;
however, portions of the Site were infested with such dense thickets of this shrub that they were
competing with planted woody and herbaceous vegetation. A cut/spray treatment was applied in MY5
to minor pockets of groundsel re-sprouts. During MY7, resprouts were present along Norkett Branch
Reach 1 and UT1; however,they are now less of a competition threat to established planted vegetation.
Soil amendments were applied to areas of low woody growth between November 2019 and July 2020.
Visual assessments that were conducted in November 2020 indicate improved tree growth across the
site. Areas of poor woody growth decreased from approximately 10%of the planted easement acreage
in MY6 to 1% in MY7 based on the mapping threshold of 0.25 acres. Minor encroachment into the
conservation easement occurred along Norkett Reach 1 and UT1 during MY7 because of harvesting in
adjacent row crop fields.
Adaptive Management- Vegetation
As warranted, future adaptive management activities may be employed through close-out to continue
to improve growth rates of planted woody stems in targeted areas. Areas noted with invasive plant
populations will be monitored and treated, as necessary. Easement encroachment will be addressed
through landowner coordination and if necessary,the installation of additional conservation easement
markers.
1.2.3 Stream Assessment
A total of 20 cross-sections were installed along the stream restoration reaches. One permanent cross-
section was installed per 20 bankfull widths along stream restoration reaches, with riffle and pool
sections in proportion to DMS guidance. Each cross-section was permanently marked with pins to
establish its location. Annual cross-section survey includes points measured at all breaks in slope,
including top of bank, bankfull, edge of water, and thalweg. Photographs were taken looking upstream
and downstream at each cross-section. Stream photographs were also taken at 51 permanent
photograph reference points throughout the project area. A reach-wide pebble count was conducted
along all restoration reaches (Norkett Branch Reach 1, Norkett Branch Reach 2, UT1, UT2 Reach 1, UT2
Reach 2, UT2 Reach 3A, and UT2 Reach 3B) for classification purposes. A wetted perimeter pebble count
was conducted at each permanent riffle cross-section to characterize the pavement.
Riffle cross-sections on the restoration reaches should be stable and should show little change in bankfull
area, maximum depth ratio, and width-to-depth ratio. All riffle cross-sections should fall within the
parameters defined for channels of the appropriate Rosgen stream type. If any changes do occur, these
changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators
of instability include a vertically incising thalweg or eroding channel banks. Changes in the channel that
indicate a movement toward stability or enhanced habitat include a decrease in the width-to-depth ratio
in meandering channels or an increase in pool depth.Substrate materials in the restoration reaches should
Norkett Branch Stream Mitigation Site
Monitoring Year 7 Annual Report- FINAL 1-4

indicate a progression towards or the maintenance of coarser materials in the riffle features and smaller
particles in the pool features.
Morphological surveys for MY7 were conducted in May 2020. All streams within the Site appear stable
and have met success criteria. Riffle cross-section dimensions fell within the parameters defined for
channels of the appropriate Rosgen stream type (Rosgen 1996) and generally show little change in the
bankfull area, maximum depth ratio, or width-to-depth ratio. Minor channel adjustments were
documented at cross-sections 3 (Norkett Branch Reach 1), 6 (Norkett Branch Reach 2), 9 (UT1), 10(UT1),
14 (UT2), and 15 (UT2). Cross-section 3 (pool) exhibited minor bank scour on the lower, left (outer)
bank.The scour was not noticeable during field assessments which could be attributed to the
establishment of woody streambank vegetation. Bed scour at cross-section 6 (riffle) may be the related
to large storm events during late MY6 coupled with previous beaver activity immediately upstream of
the cross-section. Cross-section 9 (riffle) exhibited slight deepening in the center of the channel which
could be attributed to the continued establishment of dense woody vegetation including silky dogwood
(Corpus amomum) and silky willow (Salixsericea) on both streambanks. Bed and bank elevations shifted
slightly downward at cross-section 10 (pool). No instability was noticeable during field assessments.
Minor aggradation was recorded at cross-section 14 (pool) and 15 (riffle).The aggradation at cross-
section 14 appears to be a natural adjustment in response to sediment transport. Cross-section 15
aggraded back towards design bed elevations after degradation in MY3. Subtle changes in cross-sections
are expected and do not indicate instability.
In-stream structures used to enhance channel habitat and stability on the outside bank of meander
bends, such as brush toe, are providing stability and habitat as designed. Per the Mitigation Plan
(Wildlands 2013), pattern data will only be completed if there are indicators from the dimensions that
significant geomorphic adjustments indicating a trend toward vertical or lateral instability. No changes
were observed that indicated a change in the radius of curvature or channel belt width; therefore,
pattern data was not collected or included in the MY7 report. Visual assessment during MY7 revealed
little to no eroding banks.
In general, substrate materials in the restoration reaches indicate maintenance of coarser materials in
the riffle features and finer particles in the pool features. Fluctuations in grain size distribution were
documented with MY7 pebble counts; however, distributions generally fell within previous ranges
indicative of cyclic changes in sediment transport.
Please refer to Appendix 2 for the stream visual assessment tables,the CCPV maps, and stream
reference photographs. Refer to Appendix 4 for the morphological data and plots. Additional stream
photographs were collected in 2020 to further document conditions at the upstream end of Norkett
Branch (Station 100+00 to 103+00). During the monitoring phase of the project, a portion of Norkett
Branch immediately above the Site had been channelized for the agricultural purposes. Visual
assessment did not reveal any noticeable impacts from the upstream channelization. Refer to Appendix
7 for additional stream photographs.
1.2.4 Stream Problem Areas
One isolated area of bank scour was noted at Station 109+60 of Norkett Branch.The scour is
approximately 10 feet in length along the left bank.The scour may have developed in response to
instream deposition at that location which may be directing stream velocity vectors towards the left
bank. Minor bank grading and live staking were performed in MY7 at Station 130+75 of Norkett Branch
Reach 2 and Station 302+00 of UT2 to address areas affected by previous beaver dams. In October 2020,
one beaver dam was observed at Station 128+50 of Norkett Branch Reach 2.Trappers with the U.S.

process of removing beaver at that location. The Site will be monitored for beaver activity through
closeout.
Adaptive Management-Stream
Wildlands will continue to monitor the streams for potential areas of concern and if necessary, repairs
may be implemented. Refer to Appendix 2 for the stream visual assessment tables,the CCPV maps,
reference photographs, and photographs of the stream problem areas.
1.2.5 Hydrology Assessment
Hydrologic monitoring was accomplished using both manual crest gage readings and In-situ Rugged Troll
100 pressure transducers installed at three surveyed cross-sections throughout the Site (XS6 on Norkett
Branch Reach 2, XS9 on UT1, and XS18 on UT2 Reach 3A). Rainfall data was used from a nearby weather
station at the Monroe Airport (KEQY) (NCCRONOS, 2020).To meet hydrological success criteria, two or
more bankfull events must occur in separate years within the restored reaches by the end of MY7. The
success criteria were met for the project after MY3. During MY7, multiple bankfull events were recorded
along Norkett Branch, UT1, and UT2. Please refer to Appendix 5 for hydrology data.
1.2.6 Water Quality BMPs
Water quality samples were collected during the monitoring period to assess the functionality of the
Step Pool Storm Conveyance BMP (SPSC BMP) and the Pocket Wetland BMP (PW BMP). This sampling is
not part of the success criteria for the project. However, the following expected rates for pollutant
removal were established in the Mitigation Plan (Wildlands, 2013) and in accordance with published
rates of removal from similar BMP approaches. The SPSC BMP is expected to provide similar pollutant
removal rates as the published removal rates of a bioretention area with internal water storage
(NCDWQ, 2007), which are 85%TSS removal,40%TN removal, and 40%TP removal. The PW BMP is
expected to provide 60%TSS removal, 20%TN removal, and 45%TP removal, which is similar to
extended detention wetlands (Center for Watershed Protection, 2000 and United States Environmental
Protection Agency, 2012).
The monitoring plan calls for quarterly sampling; however, samples were unable to be obtained during
Q1 and Q4 due to the timing and intensity of rain events. Inflow and outflow points were sampled at
each BMP after storm events on 4/30/2020 (Q2) and 9/18/2020 (Q3). First flush style sample bottles
were used to capture stormflow, which filled during the rain event at a pre-determined stage height and
were retrieved within 24 hours. Samples were analyzed for total suspended solids (TSS), phosphorus as
total phosphorus (TP), nitrogen as total nitrogen (TN), Nitrate/Nitrite (NOx), and Total Kjeldahl Nitrogen
(TKN), by Waypoint Analytical. Refer to in Appendix 6 for water quality sampling results and pollutant
removal rates.
The SPSC BMP provided pollutant removal of 89%of TN in the Q1 sample but an increase of 273% in TN
was recorded in Q3. TP removal ranged from 40%to 53%in MY7 SPSC samples.TSS increased by 221%in
the Q1 event but removal of 57%was documented in the Q3 sample.
PW BMP Q1 samples showed increases in TN and TP of 58%and 126% respectively but a decrease in TSS
of 97%. The PW BMP provided removal rates of 26% (TN), 67% (TP), and 71% (TSS) in the Q3 sample.
1.2.7 Wetland Monitoring
A permanent photo station (photo point#16) was established in the existing wetland complex along
Norkett Branch Reach 1 near station 104+00 on the left floodplain to visually monitor Site conditions of
the existing wetland. The photo point(#16) is included in the Stream Photographs section of Appendix 2.
The wetland complex is maintaining hydrology and supports a wetland plant community composition.
Soil boring data points were collected in April 2020 within the wetland complex as requested by the IRT
Norkett Branch Stream Mitigation Site
Monitoring Year 7 Annual Report- FINAL 1-6

at the 2020 credit release meeting. Hydric soil indicators were documented at each soil boring. Refer to
Appendix 7 for soil boring descriptions and photographs. Soil boring locations are included on CCPV
maps in Appendix 2.
1.3 Monitoring Year 7 Summary
Overall,the Site has met the required stream,vegetation density, and hydrology mitigation success
criteria for MY7. The average planted stem density for the Site is 405 stems per acre meets final density
criteria. The MY7 average stem height was 12.5 feet which is a 42% increase from the MY6 average stem
height of 8.8 feet. Most vegetation plots exceed the 10-foot average stem height per plot final success
criteria except for eight plots that are trending towards the 10-foot average. Morphological surveys
indicate that the channel dimensions are stable and functioning as designed. Visual assessment indicates
the channels show little to no sign of instability within the bed, bank, or engineered structures. All
restored channels (Norkett Branch, UT1, and UT2) recorded multiple bankfull events during MY7.The
hydrological success criteria for the Site were achieved after MY3. Water quality monitoring during MY7
indicated partial pollutant removal in both stormwater BMPs. MY7 is the final year of monitoring and
the Site will be presented to the IRT for regulatory closeout in 2021.
Summary information/data related to various project and monitoring elements can be found in the
tables and figures in the report appendices. Narrative background and supporting data can be found in
the Mitigation Plan documents available on the DMS website. All raw data supporting the tables and
figures in the appendices are available upon request.

Section 2: METHODOLOGY
Geomorphic data collected followed the standards outlined in The Stream Channel Reference Site:An
Illustrated Guide to Field Techniques(Harrelson et al., 1994) and in the Stream Restoration:A Natural
Channel Design Handbook(Doll et al., 2003). Longitudinal and cross-sectional data were collected using
a total station and were georeferenced to established benchmarks and NC State Plane coordinates.
Morphological surveys were conducted using a total station tied to these geo-referenced (control)
points. Reachwide pebble counts were conducted along each restored reach for channel classification.
Cross-section substrate analyses conducted in each surveyed riffle followed the 100-count wetted
perimeter methodology to characterize pavement. All CCPV mapping was recorded using a Trimble
handheld GPS with sub-meter accuracy and processed using was Pathfinder and ArcView. Crest gauges
were installed during the baseline monitoring period in surveyed riffle cross-sections and are monitored
quarterly. Hydrology attainment installation and monitoring methods are in accordance with the USACE
(2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-NCEEP Level
2 Protocol (Lee et al., 2008).

1 Prior to MY5,bankfull dimensions were calculated using a fixed bankfull elevation.
2 MY5-MY7 Bank Height Ratio are calculated based on the As-built(MVO)cross-sectional area as described in the Standard Measurement of the BHR Monitoring Parameter document provided by the NCIRT and NCDMS(9/2018).The remainder of the cross-section dimension
parameters were calculated based on the current year's low bank height.
3 MY3 calculations were adjusted on Cross-section 8 because they were found to omit a portion of the bankfull area.

1 Prior to MYS,bankfull dimensions were calculated using a fixed bankfull elevation.
2 MYS-MY7 Bank Height Ratio are calculated based on the As-built(MYO)cross-sectional area as described in the Standard Measurement of the BHR Monitoring Parameter document provided by the NCIRT and NCDMS(9/2018).The remainder of the cross-section
dimension parameters were calculated based on the current year's low bank height.
3 Entrenchment Ratio(ER)is the floodprone width divided by the bankfull width.ER in MY5-MY7 is based on the width of the cross-section,in leiu of assuming the width across the floodplain as was done in MY0-MY4.
