1ProjectSummary
1.1ProjectLocationandDescription
The Scarborough Mitigation Project (“Project”) is a mitigation bank under the WLS Neuse 02 Umbrella
Mitigation Bank. The Project is located approximately four miles southwest of the Town of Goldsboro in
Wayne County, NC (35.3211000, -77.98972222). The Project is located within the 8-digit HUC 03020202,
in the NC Department of Environmental Quality (NCDEQ) sub-basin 03-04-05 (Warm Water Thermal
Regime).
The Project involved the restoration, enhancement, and permanent protection of seven stream reaches
and their riparian buffers totaling approximately 11,306 linearfeet of streams. The Project also included
the preservation, re-establishment, and enhancement of riparian wetlands totaling 117.95 acres on the
site.The mitigation plan provides a detailed project summary and Table 1 provides a summary of project
assets. Figures1a,1b,and1c illustratethe projectmitigationcomponents.
Monitoring Year 2 (MY2) activities occurred in Juneand October 2022. This report presents the data for
MY2. The Project meets the MY2 success criteria for stream hydrology, stream horizontal and vertical
stability, streambed condition and stability, andstream flow. Of the 26 groundwater gauges, 11 are
meeting the proposed hydroperiod. Of the 26 fixedvegetation plots, 23 aremeeting interim success
criteria. All 15 random vegetation transects are meeting interim success criteria.Based on these results,
the Project is on a trajectory to meetsuccess criteriain Monitoring Year 3 (MY3). For moreinformation
on the chronology of the project history and activity, refer to Appendix A, Table 2. Relevant project contact
information is presented in Table 3 and project background information is presented in Table 4.
1.2ProjectGoalsandObjectives
The Project will meet the goals and objectives described in the Scarborough Final Approved Mitigation
Plan and will address general restoration goals and opportunities outlined in the NC DMS Neuse River
Basin RBRP (DEQ 2010). More specifically, watershed goals and management strategies will be met by:
•Reducing sediment, soil erosion, turbidity, and nutrient inputs such as nitrogen and
phosphorus to the Neuse River Watershed.
•Restoring, enhancing, preserving, and protecting headwater streams, wetlands, riparian
buffers, and aquatic habitat functions.
•Improving riparian corridor management and targeting restoration of impacted streams
and riparian buffer areas.
Toaccomplish these project-specific goals,thefollowingobjectiveswillbemeasuredtodocument
overall project success:
•Provide a floodplain connection to the incised/channelized Project stream reaches by
maintaining bank height ratios (BHRs) between 1.0 – 1.2, thereby promoting a more natural
headwater flow regime and overbank flood flows;
•Improve wetland hydrology and vegetation to degraded wetlands by plugging ditches and
establishing wet tolerant native species vegetation;
•Improve channel bedform diversity by increasing scour pool spacing and depth variability;
1

•Improve aquatic habitat and fish species diversity and migration through the addition of in-
stream cover and native woody debris; and
•Site protection through a 230.838-acre conservation easement with a minimum width of
50 feet from the top of the restored stream banks. The easement protects all project
streams, wetlands, and aquatic resources in perpetuity.
1.3ProjectSuccessCriteria
The success criteria for the Project will follow approved performance standards and monitoring protocols
from the final approved mitigation plan; which was developed in compliance with the USACE October
2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008
Compensatory Mitigation Final Rule. Cross-section and vegetation plot data will be collected in Years 0, 1,
2, 3, 5, and 7. Stream and wetland hydrology data and visual monitoring will be reported annually. Specific
success criteria components and evaluation methods are described below.
1.3.1Single-Thread Streams
StreamHydrology: Four separate bankfull or over bank events must be documented within the seven-
year monitoring period and the stream hydrology monitoring will continue until four bankfull events have
been documented in separate years. Stream hydrology monitoring will be accomplished with pressure
transducers installed in pools and correlating sensor depth to top of bank elevation. Recorded water depth
above the top of bank elevation will document a bankfull event. The devices will record water depth
hourly and will be inspected quarterly. In addition to the pressure transducers, traditional cork gauges
wereinstalled at bankfull elevation and will be used to document bankfull events with photographs.
StreamProfiles,VerticalStability,andFloodplainAccess:Stream profiles, as a measure of vertical stability
and floodplain access will be evaluated by looking at BHR. In addition, observed bedforms should be
consistent with those observed for channels of the design stream type(s). The BHR shall not exceed 1.2
along the restored Project stream reaches. This standard only applies to restored reaches of the channel
where BHRs were corrected through design and construction. Vertical stability will be evaluated with
visual assessment, cross-sections and, if directed by the IRT, longitudinal profile.
StreamHorizontalStability:Cross-sections willbe used to evaluate horizontal stream stability on restored
streams. There should be little change expected from as-built restoration cross-sections. If measurable
changes do occur, they will be evaluated to determine if the changes represent a movement toward a
more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g.,
settling, vegetation establishment, deposition along the streambanks, decrease in width/depth ratio).
Cross-sections shall be classified using theRosgen Stream Classification method and all monitored cross-
sections should fall within the quantitative parameters defined for channels of the design stream type.
Reference photo transects will be taken at each permanent cross-section. Lateral photos should not
indicate excessive erosion or continuing degradation of the streambanks. Photographs will be taken of
both streambanks at each cross-section. A survey tape stretched between the permanent cross-section
monuments/pins will be centered in each of thestreambank photographs. The water elevation will be
shown in the lower edge of the frame, and as much of the streambank as possible will be included in each
photo. Photographers will attempt to consistently maintain the same area in each photo over time.
2

Additional photo points will be taken annually at the culvert crossings located on the project at Casey Mill
Road and Arrington Bridge Road, and in the Enhancement II section on upper UT2.
Streambed Material Condition and Stability: There should be minimal change in the particle size
distribution of the streambed materials, over time, given the current watershed conditions and limited
upstream sediment supply. Because the streambed material and sediment supply is predominantly sand
with minimal gravel, significant changes in particle size distribution and channel substrate are not
expected.
JurisdictionalStreamFlow:Monitoring of stream flow will be conducted to demonstrate that the restored
stream systems, classified as intermittent, exhibit surface flow for a minimum of 30 consecutive days
throughout some portion of the year, during a year with normal or below normal rainfall conditions.
Stream flow monitoring will be accomplished with pressure transducers installed in pools and correlating
sensor depth to the downstream top of riffle elevation. If the pool water depth is at or above the top of
riffle elevation, then the channel will be assumed to have surface flow. The devices will record water
elevation twice per day and will be inspected quarterly to document surface hydrology and provide a basis
for evaluating flow response to rainfall events. A diagram of the flow gauge installation and measurements
can be found in Appendix E.
1.3.2Headwater Streams
Seasonal Flow: Surface flow must be documented using automatic pressure transducers (flowgauges).
Continuous surface water flow within the valley or crenulation must be documented to occur every year
forat least 30 consecutive days during the prescribed monitoring period. This will be accomplished in the
sameapproach as Jurisdictional StreamFlow above.
ChannelFormation:During monitoring years 1 through 4, a preponderance of evidence must demonstrate
a concentration of flow indicative of channel formation within the topographic low-point of the valley or
crenulationas documented by the following indicators:
Scour (indicating sediment transport by flowing water)
Sediment deposition (accumulations of sediment and/or formation of ripples)
Sediment sorting (sediment sorting indicated by grain-size distribution within primary flow path)
Multipleobserved flow events (must be documented by gauge data and/or photographs)
Destruction of terrestrial vegetation
Presence of litter and debris
Wracking (deposits of drift material indicating surface water flow)
Vegetation matted down, bent, or absent (herbaceous or otherwise)
Leaf litter disturbed or washed away
During monitoring years 5 through 7, the stream must successfully meet the requirements above and in
addition must demonstrate the development of stream bed and banks as documented by the following
indicators:
Bed and banks (may include the formation of stream bed and banks, development of channel
pattern such as meander bends and/or braiding at natural topographic breaks, woody debris, or
plant root systems)
Natural line impressed on the bank (visible high-water mark)
3

Shelving (shelving of sediment depositions indicating transport)
Water staining (staining of rooted vegetation)
Change in plant community (transition to species adapted for flow or inundation for a long
duration, including hydrophytes)
Changes in character of soil (texture and/or chroma changes when compared to the soils
abutting the primary path of flow)
1.3.3 Wetlands
Wetland Hydrology: The performance standard for wetland hydrology will be at least 12 percent in the
lower elevations (i.e. floodplain areas) and 10 percent along the ridges where hydric soils transition to
upland areas. These hydroperiod ranges are based on the suggested wetland saturation thresholds for
soils taxonomic subgroups provided by the IRT and as compared with on-site wetland reference data. The
proposed success criteria for wetland hydrology will be when the soils are saturated within 12 inches of
the soil surface for 10 to 12 percent (23 to 27 days) of the growing season (March 21 through November
6) based on WETS data table for Wayne County, NC. The saturated conditions should occur during a period
when antecedent precipitation has been normal or drier than normal for a minimum frequency of 5 years
in 10. Precipitation data will be obtained from Seymour-JohnsonAFB AirportinGoldsboro, which is
approximately one milenortheastfrom the Project site. A tipping bucket rain gauge was installed on- site
for reference data.
1.3.4Vegetation
Vegetation monitoring will occur in the fall each required monitoring year, prior to leaf drop. Plots will be
monitored in years 1, 2, 3, 5, and 7. Vegetative success for the Project during the intermediate monitoring
years will be based on the survival of at least 320, three-year-old planted stemsper acre at the end of
Year 3 ofthe monitoring period; and at least 260, five-year-old, planted stemsper acre that must average
seven feetin height at the end of Year 5 of the monitoring period. The final vegetative restoration success
criteria will beachieving a density of no less than 210, seven-year-old planted stems per acre that must
average 10 feet in height in Year 7 of monitoring.
1.3.5Visual Assessment
WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments
of all stream reaches will be conducted twice per monitoring year with at least five months in between
each site visit for each of the seven years of monitoring. Photographs will be used to visually document
system performance and any areas of concern related to streambank and bed stability, condition of in-
stream structures, channel migration, excess sediment, active headcuts, live stake mortality, invasive
plant species or animal browsing, easement boundary encroachments, and general streambed conditions.
Permanent photo points will be at the cross-sections, culvert crossings, and Enhancement II reaches.

3MonitoringYear2AssessmentandResults
The dates of Year 2 monitoring activities are detailed in Appendix A, Table 2. All Year 2 monitoring data is
presented in this report and in the appendices. The Project is on track for meeting stream success criteria.
Vegetation on the site is doing well overall, threeof the 26 fixedvegetationplots are not meeting interim
criteria. All 15 random vegetation transectsmet interim success criteria. Wetland gauges are not fully
5

successful and WLS willcontinue to monitor them closely and implement adaptive management when/if
necessary. All monitoring device locations are depicted on the CCPV (Figure 1a-1c).
3.1MorphologicalAssessment
3.1.1 Stream Horizontal Pattern & Longitudinal Profile
Visual assessment was utilized for assessment of MY2 horizontal and vertical stream stability. The visual
assessments for each stream reach document MY2 stream channel pattern and longitudinal profiles, and
in-stream structure location/function, whichalign withthe profile design parameters and MY0/baseline
conditions (Appendix D). The MY2 planform geometry and dimensions fall within acceptable ranges of the
design parameters for all restored reaches. Minor channel adjustments in riffle slopes, pool depths and
pattern were observed based on appropriate sediment transportand stream bank vegetation
establishment.
During MY2, three smallbeaverdams were found on UT1-R1near stations 17+00, 24+50, and 31+50. WLS
will be contactingthe North Carolina Beaver Management Assistance Program early in MY3 to trap
beavers on site and remove the dams. Beaver impacts to the site were minimal during MY2 and did not
negatively affect stream pattern and profile or vegetation on either reach. WLS will continue to monitor
these areas closely and any remedial action taken during MY3 will be noted in future reports.
3.1.2 Stream Horizontal Dimension
The MY2 channel dimensions generally match thedesign parametersand are within acceptable andstable
ranges of tolerance. Eight of the 14 cross-sections are located in coastal headwater restoration reaches
andthe remaining six cross-sectionsare located in Priority I/II single-thread restoration channels. Allsix
of the PI/II cross-sections show little to no change in the bankfull area and bank height ratios are less than
1.2. It is expected that over timethat some pools may accumulate finesediment and organic matter;
however,this is notan indicatorofchannel instability. Maximum riffle depths are also expected to
fluctuate slightly throughout the monitoring period as the channels adjust to the new flow regimeand
catchment conditions. Headwatercross-sections are expected to fluctuate throughout the initial
monitoring years 1-4 as the headwater streams exhibit channel formation.
3.2StreamHydrology
3.2.1Stream Flow
The flow gauges on UT1-R1, UT1B, UT3, and UT2 (upper)document that the stream exhibited surface flow
for a minimum of 30 consecutive days throughout the monitoring year (Appendix E, Figure 2). Flow gauges
th
were re-surveyed for data accuracy on October 4, 2022, and flow depths were congruent with MY0.
Additionally, to determine if rainfall amounts are normal for the given year, precipitation data was
obtained from the onsite rain gauge, and compared with data from the NC State Climate Office station
KGSB, located at Seymour-Johnson AFB approximately one mile northeastof the site. Rainfall totals for
th
the site were below the 30percentile in four of the seven months included in the growing season.

3.2.2Bankfull Events
During MY2, bankfull events were recorded on both pressure transducers(and the associated crest
gauges). UT1-R2gaugerecorded fiveevents with a maximum event of 0.419feet above bankfull elevation
th
occurring on January 16, 2022. UT2-R2gaugerecorded sevenevents with a maximum event of 0.375
th
feet above bankfull occurring on January 16, 2022. Both traditional cork crest gauges also captured
bankfull events. The associated data is in Appendix E.
3.2.3Headwater Stream Channel Formation
During MY2, streams UT1-R1, UT1B, UT2,and UT3 all exhibited evidence indicative of channel formation
within the topographic low-point of the valley. See Appendix D (Table 6d)for channel forming evidence
documentation.
3.2.4Wetland Hydrology
Data for the twenty-sixgroundwater wells installed is available in Appendix E.All 26 wellsare in creditable
wetland areas. Thirteengroundwater wellsare located within wetlands with a proposed minimum
hydroperiod of 10percent. Of these thirteen, threeare meeting the wetland hydrology criterion. The
other thirteen wetland groundwater wells are located within wetlands with a proposed minimum
hydroperiod of 12 percent. Of these thirteen, eightare meeting the wetland saturation threshold. Wewill
continue to monitor the wetland gaugescloselyand investigate potential adaptive management options
to present to the IRTfollowing the collection of Spring 2023 data. Rainfall totals for the site were below
th
the 30percentile in fourof the sevenmonths included in the growing season. Thisaffectedhydrology
negatively throughout the siteas compared to 2021 groundwater data. Groundwater well locationsare
shown on Figures 1a-1cand data is includedin Appendix E (Figures 5A and 5B).
3.3 Vegetation
Monitoring of the 26 permanent vegetation plots (joint 404/401) and 15 random vegetation transects
(50m x2m)was completed during the thirdweek of October2022. Vegetationdata can be found in
Appendix C with the associated photos located in Appendix B. The MY2 average stem density is 418stems
per acre, which exceeds the interim measure ofvegetativesuccess of at least 320 planted stems per acre
at the end of the third monitoring year.Three of the26 fixedvegetation plots did not meet the interim
measureof success for stems per acre, but WLS anticipates volunteers in coming years. All 15random
vegetation transects met the interim measure of success for stems per acre. Low stem densities in these
7

plots arelikely due to prolongedsaturation. Areas surrounding the failing vegetation plots are doing well
based on visual observations. At this time no remedial action is proposed and the areas with lower stem
counts will be monitoredclosely in MY3. Bald cypress (Taxodium distichum), ironwood (Carpinus
caroliniana), sycamore (Platanus occidentalis), and water oak (Quercus nigra) volunteerswere noted in
MY2, and more species are expected to establish in upcoming years.Volunteers included in the approved
mitigation plan were included in stem count data.
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation
is becoming well established throughout the project.
A significant population of kudzu (Pueraria montana) was documented west of UT2 (upper) prior to
construction. Initial spray treatments occurred in September 2020. No treatments were conducted in
during MY2. This area will be closely monitoredduring MY3, and re-sprouts will be treated as needed to
prevent further establishment.During MY1 monitoring activities, WLS staff noted the presence of small,
isolatedpopulations of common cattail (Typha latifolia) on the project site. There are no adverse effects
associated with the cattail (i.e., aggradation, competition). WLS staff willtreat cattails during the
appropriate treatment window during MY3, as needed. Any subsequent vegetationmanagement for
problem or invasive species will be included in the MY3 report.
4Methods
Stream cross-section monitoring was conducted using a Topcon RL-H5 Laser Level. Morphological data
were collected at 14 cross-sections. Survey data were imported into Microsoft Excel® for data processing
and analysis. The stage recorders include an automatic pressure transducerset in PVC piping in the
channel. The elevation of the bed and top of bank at each stage recorder location was recorded to be able
to document presence of water in the channel and out of bank events. Visual observations (i.e. wrack or
debris lines) and traditional cork crest gauges will also be used to document overbank flow bank events.
Vegetation success is being monitored at a total of 26 permanent vegetation plots(each 10m x 10m)and
15random vegetation plots/transects (each 2m x 50m). The 26 permanent vegetation plots are joint
404/401and the 15 transects are 404 only. Vegetation plot monitoring follows the CVS-EEP Level 2
Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species
composition and density of planted species. Data are processed using the CVS data entry tool. In the field,
the four corners of each fixed plot were permanently marked with PVC at the origin and rebar at all
corners. Random transectswere marked in the field with flagging tape on each end of the transectand
each stem was markedwith flagging tape. Photosof each fixed plot are to be taken from the origin each
monitoring year. Tree species and height will be recorded for each planted stem. Random transects will
beGPS located/mapped and new locations will be monitored in subsequent years.
Wetland hydrologyis monitored to document success in wetland restoration and enhancement areas
where hydrology was affected. This is accomplished with 26 recording pressure transducer gauges
(located in groundwater wells) that record twice daily groundwater levels. Pressure transducers are HOBO
Water Level (13ft) Data Loggers made by Onset. Twenty-six data loggers have been installed within the
wetland crediting area. Of the 26 located in the credited areas, one was installed within a reference
wetland area. One automatic pressure transducer is installed above ground for use as a barometric
reference. Gauges are downloaded quarterly and wetland hydroperiods are calculated during the growing
8

season. Gauge installation followed current regulatory guidance. Visual observationsof primary and
secondary wetland hydrology indicators are also recorded during quarterly site visits.
