Year 7Monitoring Report• Wayne County, North Carolina•August2022
1PROJECT GOALS, BACKGROUND AND ATTRIBUTES
1.1Location and Setting
The Arrington Bridge III WetlandMitigation Project is located in Wayne County approximatelythree
miles southwest of Goldsboro, NC. To access the Site from the town of Goldsboro, travel south on NC
HWY 117, and turn left onto Arrington Bridge Road (NC Highway 581). Turn right onto the dirt
entrance road immediately after crossing the railroad tracks (approximately 0.15 miles). Turn left after
0.3 miles. In 0.1 miles, follow the left fork to access the northern end of the Site. Following the path to
the right will lead to the middle and southern portions of the Site.
The site is located in the Neuse River Basin within Cataloging Unit 03020201 (NCDWQ sub-basin 03-
04-12). The project is located within the Neuse River Basin (8-digit USGS HUC 03020201, 14-digit
USGS HUC 03020201200040.
1.2Project Goals and Objectives
The Arrington Bridge III WetlandMitigation Project providesnumerous ecological and water quality
benefits within the Neuse River Basin. While many of these benefits are limited to the project area,
others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching
effects. Expected improvements to water quality, hydrology, and habitat are outlined below.
Design Goals and Objectives
Benefits Related to Water Quality
Benefit will be achieved through cattle exclusion and direct removal of fecal inputs, filtering of runoff
Nutrient removalthrough wetlandareas, the conversion of active cattle pasturesto forested wetlands, and improved
denitrification and nutrient uptake through wetlandzones.
Benefit will be achieved through the restoration of buffer areas that will receive and filter runoff,
Runoff filtration
thereby reducing nutrients and sediment concentrations reaching water bodies downstream.
Benefits to Flood Attenuation
Benefit will be achieved through the restoration of wetlandareas which will infiltrate more water
Water storage
during precipitation events than under current site conditions.
Benefit will be achieved through the increased storage of precipitation in wetlandareas, ephemeral
Improved groundwater
depressions, and reconnection of existing floodplain. Greater storage of water will lead to improved
recharge
infiltration and groundwater recharge.
Benefits Related to Ecological Processes
Benefit will be achieved by restoring riparian wetlandhabitat to appropriate bottomland hardwood

1.3.1Wetland Restoration Type and Approach
The Arrington Bridge III Wetland Mitigation project provides32.51wetland mitigation units through
a combination of Wetland Restoration and two levels of Wetland Enhancement. The existing pasture
areas on the Site aretreated with Wetland Restoration at a credit ratio of 1:1. Wetland Restoration
activities included: plugging the main channel and side ditches, removing fill, and regrading the area
to reconstruct historical contours. A credit ratio of 3:1 wasput in placefor higher-uplift wetland
enhancement areas, including a drained area of planted cypress, an excavated pond, and forested areas
along the north side of the main ditch. A ratio of 5:1 was put in placefor the lower-uplift wetland
enhancement areas, which are primarily along the north side of the main ditch. Both levels of Wetland
Enhancement weretreated by enhancing the hydrology and providing long-term protection. Thiswas
accomplished by filling the ditches across the site to raise the water table and restore a more natural
drainage pattern. Additionally, the pond wasbackfilled with the adjacent spoil pile and planted with
trees and a permanent seedmix. Although this was restored to a wetland, itreceivesEnhancement
credits at aratio of 3:1 because the pond was already a jurisdictional feature.
1.3.1.1Wetland Restoration Summary
The primary wetland restoration activities included:
• The backfilling and stabilizing of the main channelized drainage feature and existing side ditches;
• The fill material on one of the access roads wasremoved and stabilized to restore the natural flow
pattern, and the pond wasbackfilled with the adjacent spoil pile;
• Areas of cut and fill werere-graded to create a continuous bottomland wetland system.
Plugging ditches and main channelized drainage feature
Plugging of the main feature and side ditches wasaccomplished through a combination of backfilling
and the construction of ditch plugs throughout the easement area. Approximately 8,600 linear feet of
open ditch wasbackfilled within the easement boundary. Ditches arefilled, compacted, and graded to
the adjacent floodplain elevation. Typical ditch plugs are20 feet wide and extend above the top of the
ditch bank elevation a minimum of 6 inches. Plugs areconstructed ofcompacted fill placed in 12-inch
lifts with the upper 18 inches minimally compacted to allow for plant growth. Plugs are spaced such
that successive plugs are no more than 6 inches in elevation below one another. At the point of departure
from the conservation easement, a headwater-type channel isgraded to the existing ditch elevation.
When possible, ditch plugs areconstructed using excavated material from the restoration and
construction of wetland pools.
Fill Removal, Pond Backfill, and regrading of site
Disturbed soils underlain by hydric soils (as described in the soils report) weregraded to allow for a
morenatural hydrologic regime and function. Additionally, the fill material on the access roads was
removed to restore the natural flow pattern of the site. The restoration site is very gently sloping (less
than one percent) but does contain approximately threefeet of elevation difference across thesite.
Several decades of agricultural management and mining operations has eliminated microtopography
2

Year 7Monitoring Report• Wayne County, North Carolina•August2022
across the site. As outlined in the soils report located in the Mitigation Plan, approximately 12.6 acres
of the project area is described as disturbed soils having hydric indicators and lacking wetland
hydrology. These includedlarge areas in a lower landscape position located adjacent to visible borrow
pits. The soilsin these areas had variable textures that wereexhibiting hydricindicators. All of this area
was in pasture and being grazed by cattle. One excavated pond isbackfilled with soil from the adjacent
spoil pile. The filled pond is considered enhancement due to the jurisdictional status of the existing
open water habitat. The entire conservation easement wasdisked to break up the plow layer, increase
surface roughness, and promote infiltration.
1.3.1.2Proposed Wetland Hydrology
The Arrington Bridge III Mitigation Site was once a Cypress Gum Swamp wetland subject to prolonged
inundation as indicated by soils mapping, historical aerial photography, and personal communication
with landowners. By 1974, the area was cleared, much of the borrow removed, and conversion of area
to agricultural production was occurring. Theditch system was mostly in place. The restoration plan
for the site consistedoffilling and stabilizingditches, converting active pasture to a bottomland wetland
system, restoring bottomland hardwood forests, and enhancing the hydrology of existing wetlands. The
backfilling and plugging of ditches lengthenwetland hydroperiods by halting artificial subsurface
drainage and preventing rapid surface drainage. Periodic flooding is vital to sustain plants and wildlife
characteristic of riverine wetlands (Ainslie, 2002). The drainage area for the project area is
approximately 0.63 square miles. The restored wetlands have a variable flooding regime due to the
small size of the drainage area.
1.4Project History, Mitigation Bank Establishment, Contacts and Attribute Data
1.4.1Project History
The Arrington Bridge III WetlandMitigation Site was restored by EBX Neuse I, LLC (EBX).EBX is
anentity of Resource Environmental Solutions LLC (RES).Tables 2, 3, and 4 (Appendix A) provide a
time sequence and information pertaining to the project activities, history, contacts, and baseline
information. EBX, acting as the Bank Sponsor, established a Conservation Easement (CE) and will
monitor the Site for a minimum of seven years. The Mitigation Plan provides detailed information
regarding bank operation, including long term management and annual monitoring activities. The Bank
Sponsor has conveyed the CE to the long-term land steward, the North Carolina Wildlife Habitat
Foundation (NCWHF). The Bank Sponsor will ensure that the conveyed CE will allow for the
implementation of an initial monitoring phase, which will be developed during the design phase and
conducted by the Bank Sponsor. The conveyed CE will allow for yearly monitoring and, if necessary,
maintenance of the Site during the yearly monitoring phases. These activities will be conducted in
accordance with the terms and conditions of the Neu-Con Wetland and Stream Umbrella Mitigation
Bank made and entered into by EBX, USACE, and NCDWR.
1.4.2Project Watersheds
The easement totals 57.40 acres with one unnamed tributary entering the easement and draining into a
channelized wetland ditch, which runs the length of the easement. The total drainage area at the
downstream limits of the project is 403 acres (0.63 mi2). The land use in the project watershed is
approximately 41 percent cultivated cropland, 18 percent pasture, 16 percent forested, eight percent
residential, eight percent commercial, and seven percent managed open space.

2SUCCESS CRITERIA
The success criteria for the Arrington Bridge III Site followsaccepted and approved success criteria
presented in the North Carolina Wetland Mitigation Guidelines and subsequent agency guidance.
Specific success criteria components are presented below.
2.1Wetland Success Criteria
2.1.1 Wetland Hydrology Criteria
The Natural Resources Conservation Service (NRCS) has a current WETs table for Wayne County
upon which to base a normal rainfall amount and average growing season. The closest comparable data
station was determined to be WETS station NC713 Goldsboro S Johnson AFB. This station is located
at the Seymour Johnson Air Force Base approximately 1.5 miles east of the proposed mitigation site.
The growing season for Wayne County is 262 days long, extending from March 4 to November 21, and
is based on a daily minimum temperature greater than 28 degrees Fahrenheit occurring in five of ten
years.
Because of the surface roughing and shallow depressions, a range of hydroperiods and inundation is
expected. The hydrology success criterion for the site is to restore the water table at the site so that it
will remain continuously within 12 inches of the soil surface for at least eight percent of the growing
season (approximately 21 days) at each groundwater gauge location.
Restoration and enhancement wetland gauge data iscompared to reference wetland gaugedata in
growing seasons with less than normal rainfall. In periods of low rainfall, if a restoration gauge
hydroperiod exceeds the reference gauge hydroperiod, and both exceed five percent of the growing
season, then the gauge will be deemed successful. If a gauge location fails to meet these success criteria
in the seven-yearmonitoring period, then monitoring may be extended, remedial actions may be
undertaken, or the limits of wetlandrestoration will be determined.
2.2VegetationSuccess Criteria
Specific and measurable success criteria for plant density within the wetland areas on the site follows
IRT Guidance. Vegetation monitoring plots are aminimum of 0.02 acres in size andcover a minimum
of two percent of the planted area. Vegetation monitoring occursannually in the fall of each year. The
measures of vegetative success for the site vary based on the planting zones outlined in the mitigation
plan.
The interim measures of vegetative success for the planted areas in the site isthe survival of at least
320 planted three-year old trees per acre at the end of Year 3 and 260 five-year old trees per acre at the
end of Year 5. The final vegetative success criteria isthe survival of 210 trees per acre at the end of
Year 7 of the monitoring period.
Survival isdetermined at the plot level, not averaged at the site level. No areas areplanted with more
than 50 percentof one species comprising the total composition. In addition, planted vegetation should
show ageneral trend toward successful establishment of the target communities with vigor and height
growth. Specific height criteria are not specified due to the variability of species and site conditions.
2.3Scheduling/Reporting
The Bank Sponsor followsthe guidance document published by NC DMS, “Monitoring Requirements
and Performance Standards for Stream and/or Wetland Mitigation” dated November 7, 2011 and the
2003 USACE Stream Mitigation Guidelines. Due to the fact that this project is a private mitigation
4

Year 7Monitoring Report• Wayne County, North Carolina•August2022
bank and not an NC DMS project, monitoring documents follow DMS guidelines only to the extent
necessary for IRT approval. A monitoring report will be generated by December 31st of each
monitoring year documenting activities of the site, and submitted to the IRT. The monitoring program
isimplemented to document system development and progress toward achieving the success criteria.
The monitoring program will be undertaken for seven years or until the final success criteria are
achieved, whichever is longer.
3MONITORING PLAN
Annual monitoring data isreported using the IRT monitoring template. The monitoring report provides
a project data chronology that facilitatesan understanding of project status and trends, research
purposes, and assistsin decision makingregarding project close-out. The success criteria for the
Arrington Bridge III site followscurrent accepted and approved success criteria presented in the North
Carolina Wetland Mitigation Guidelines, and subsequent agency guidance. Specific success criteria
components are presented in the table below. Monitoring reports will be prepared annually and
submitted to the IRT.

3.1Visual Assessment Monitoring
Visual monitoring of all mitigation areas isconducted a minimum of twice per monitoring year by
qualified individuals. The visual assessments include vegetation density, vigor, invasive species, and
easement encroachments. Digital images aretaken at fixed representative locations to record each
monitoring event, as well as any noted problem areas or areas of concern. Results of visual monitoring
arepresented in a plan view exhibit with a brief description of problem areas and digital images.
Photographs areused to subjectively evaluate surface hydrology, success of vegetation, and
effectiveness of erosion control measures. A series of photos over time should indicate successional
maturation of vegetation.
3.2Vegetation
Vegetation monitoring plots will be a minimum of 0.02 acres in size andcover a minimum of two
percent of the planted area. The following data will be recorded for all trees in the plots: species, height,
planting date (or volunteer), and grid location. Monitoring occurseach year during the monitoring
period. Invasive and noxious species aremonitored and controlled so that none become dominant or

Year 7Monitoring Report• Wayne County, North Carolina•August2022
alter the desired community structure of the site. If necessary, RES will develop a species-specific
control plan. Invasive and noxious species aremonitored and controlled so that none become dominant
or alter the desired community structure of the site. Table 6(Appendix B) provides a success summary
for each vegetation monitoring plot.
4MAINTENANCE AND CONTINGENCY PLAN
All identified problematic areas or areas of concern such as wetland hydrology not meeting success
criteria, erosion/instability, aggradation/degradation, lack of targeted vegetation, and invasive/exotic
species which prevent the site from meeting performance success criteria will be evaluated on a case
by case basis. The USACE will be notified if monitoring or other information indicates that the Bank
Site, or a portion of a Bank Site, is not progressing as anticipated towards meeting the site specific
performance standards as defined in the Mitigation Plan. In such an event the USACE will be provided
with recommendations for adaptive management measures, which may include site modifications,
design changes, revisions to maintenance requirements, and revised monitoring requirements. USACE
approval will be obtained prior to conducting any adaptive management activities.
4.1Wetlands
Any wetland problem areas which are identified during post construction monitoring activities are
documented and mappedon the Current Conditions Plan View (CCPV) as part of the annual monitoring
report. Wetland problem areas may include wetland hydrology not meeting success criteria. If it is
determined through IRT correspondence that remedial action is required to repairan area, a proposed
work plan will be submitted for remediation.
4.2Vegetation
Any vegetation problem areas which are identified during post construction monitoring activities are
documented and mapped on the Current Conditions Plan View (CCPV) as part of the annual stream
monitoring report. Vegetation problem areas or areas of concern may include avegetation plot not
meeting success criteria, invasive species abundance, sparse vegetation areas, etc. If it is determined
through IRT correspondence that remedial action is required to repair an area, a proposed work plan
willbesubmitted for remediation.
5MONITORING YEAR 7(MY7)
The Arrington Bridge IIIMitigation Site Year 7monitoring activities were performed throughout
2022with the most recent activity atthe end of August2022.All required Year 7monitoring data is
present below and in the appendices. Data presented shows the site has remained stable throughout
Year 7and in general has metvegetation and hydrology success criteriaand is proposed for closeout.
5.1Year 7Data Collection
5.1.1Hydrology
Wetland hydrology is monitored with 15automatic recording pressure transducer gauges that have been
installed in representative locations across the wetland restoration areas. Two wetland hydrology
gauges were installed in reference wetland areas. An onsite rain gauge is alsoinstalled to document
rainfall events. Monitoring Year 7wetland hydrology gauge data is documented in Table 9,Appendix
B.Overall, wetland hydrology data show the site has performedas planned and hasmettargeted
wetland hydroperiods. During Year 7,wetland hydrology was monitored throughAugust 2, 2022.
Data was obtained from eightof the 15 wetland hydrology gauges.The data from the remaining seven
6

Year 7Monitoring Report• Wayne County, North Carolina•August2022
wetland hydrology gauges wasunattainable due tobattery loss of HOBOwater level loggersat some
point during the MY7 monitoring year.Six of the eightwetlandhydrology gauges met the hydrology
success criteria of remaining continuously within 12 inches of the soil surface for at least 8%of the
growing season (8%is approximately 21 days). Gauge AW1 and AW3did not meet success criteria,
with 1% and 2% hydroperiods respectively. However, AW1 met success criteria fiveout ofseven
monitoring years and AW3 met success criteria in all previousyears.Hydroperiods ranged from 1% to
31%.Although wetland hydrology datawas not obtained for gaugesAW4, AW6, AW7, AW9, AW11,
AW12, and AW15in MY7,those particular gauges met success criterion (>8%) in all previous
monitoring years. Recorded rainfall data shows the site was below normal limits inMarch, April, June,
and Augustand above normal limits in Januaryand July (Table 8, Appendix B).Reference Well 2 was
destroyed during MY6and wasnot replaceddue to the continued success of other gauges onsite.
5.1.2Vegetation
Vegetation monitoring occurred on August 2, 2022.26of the 27 fixedvegetation plots andallsix
random vegetation plots exceeded the interim success criteria, 210stems per acre, in Year 7. Planted
stems per acre ranged from 121to 1,012with a mean of 535. Total stems per acre ranged from 121to
28,692with a mean of 3,349. The average planted stem height across the entire site was7.4feetwhich
includes replanted stems. When averaging the necessary number of stems to meet 210 stems per acre,
the average planted stem height is 9.6feet.Vegetation Plot 6did not meet the interim successfor
planted stems; however,theplotseemed to be isolated and contained fewer trees than their surrounding
areas. Additionally, as discussed in the subsequent paragraph of this report, theplothad high vegetative
coverage. Vegetation Plot 6 was dominated by desirable herbaceous vegetation which may have
affected tree survivability. Given the conditions and lowexpectations of additional survivability, RES
believes these areaswould not benefit from supplemental planting.
As requested by IRTduring our site visit at the end of Monitoring Year 5, RES performed herbaceous
monitoring in Monitoring Year 7at every vegetation plot. Herbaceous monitoring consisted of species
identification and percent coverage estimation within eachplot. The goalsof the herbaceous monitoring
were: 1) to evaluate ifopen water areas were prevalent on site and2)to document herbaceous diversity
to supplement our understanding of the success of areas with low tree vigor/survival. With the exception
of two plots, each plot had two to seven herbaceous species and 21species totalwere documented
across all plots.The herbaceous coverages averaged 91% and the median coverage was 100%. The
lowest coverage percentage was 50% in Plot 14; this plot has 526stems per acre and is meeting all
success criteria.Plots 2, 12, and 15 had herbaceous coverages from 55 -68%, all of these plots are
meeting success criteriafor woody stems.All other plots had at least 70% to 100% coverage. Plot 6,
which did not meet success criteria for woody stems,had 100% coverage of vegetation including
Broadleaf arrowhead (Sagittaria latifolia),cattails (Typha latifolia),Curlytop knotweed(Polygonum
lapathifolium),soft rush(Juncus effusus), and alligator weed(Alternanthera philoxeroides).The dryer
plots documented more diversity than the wetter plots. The wetter plots had less diversity buthad high
coverage andwere dominated by either Swamp smartweed (Persicaria hydropiperoides), Alligator
weed, sallow sedge, soft rush, or tearthumb.No plot exhibited areas of open water.Documented
invasive species included Alligatorweed and parrotfeather (Myriophyllum aquaticum) and nuisance
species included cattails.RES treatedcattails patches in August 2022andreducedtheir presence onsite.
The treatment of the other dominant invasive species on-site would lead to unnecessary mortality of
desirable species as well as an increase in open water areas; therefore, RES will not treat the widespread
aquatic invasives.

5.1.3Photo Documentation
Permanent photo point locations areestablished at each vegetation plot by RES’staff. Any additional
problem areas or areas of concern will also be documentedwith a digital photographduring monitoring
activities. Digital photographs of the site’s condition and vegetation plots can be found in Appendix B.
5.2Adaptive Management
RES plantedadditional trees in March 2021 in and around Plots 6 and 7, and the open water areas near
Plot 4,Plot 10, and Plot 11. This supplemental planting totaledaround 1.75 acresand consisted of 125
willow poles and 75 bald cypress containertrees.Replanting around Plots 10and 11 was not successful.
Thetwo low stem density/open water areas near Plots 10 and 11remain open and trees have failed in
these areas numerous times despite multiple replanting events. The area near VP11 is 0.23 acres of
wetland restoration and the area near VP10 is 0.17 acres of wetland enhancement (3:1)(Figure 2).In
accordance with (USDA, Biology Technical Note, October 2008), RES does not believe these areas are
attractive to waterfowl, therefore are nota risk to nearby aircraftactivity because waterfowl prefer
wetland macrotopography features that are 0.5 to 3.0 acres in size.The two areas in questionare 0.23
acres and 0.17 acres, which even combined, are still less than 0.5 acresand only make up 1% of the
restored wetland.Additionally, the size and depth of the open water areas, represent habitatattractive
to amphibiansand aquatic snakes and turtles.The table below describes macrotopography design
guidance fortargeted wetland species.
