RE: Arrington Bridge I I I Year 5 Monitoring Report (SAW — 2015 — 00360)
Ms. Dailey,
Please find attached the Arrington Bridge III Year 5 Monitoring Report. All of the wetland gauges
met the hydroperiod success criteria in MY5. Twenty-five of the 27 vegetation plots met success
with a mean of 567 stems per acre. The two plots that did not meet success only missed by one
or two trees. Per the results of Year 4 monitoring, RES completed a supplemental planting of 7.10
acres of standing water, low stem density areas in April 2020 and plans to perform a follow-up
supplemental planting of 1.75 acres this winter.
RES is requesting a 15% (4.88 WMU) credit release for Year 5 monitoring
On December 19, 2019, the IRT provided comments for the Arrington Bridge Year 4 Monitoring
Report. Please see those comments and RES' responses (in blue) below.
1. The main purpose to visit the Arrington Bridge III site was based on the Monitoring Year 4
review and the extent of the vegetative low growth or low density areas reported.
2. We started at the top of the site and initially walked through the marsh like area near VPs 4-6.
This area showed very few trees and depths ranging from 6 inches to 1.5 feet. There had been a
rain event within 48 hours.
3. We walked the entire length of the site primarily on the south side. One general observation
was that DWR felt that the low growth/density polygons were underestimated. The polygons on
the map (Figure 2) shows 23% of the site affected. DWR estimates that least 30% if not higher
show low growth/density.
RES agrees with this statement. The 23% (7.10 acres) were supplemental planted in April 2020
and an additional 5% (1.75 acres) will be supplemental planted this winter.
4. RES discussed several strategies to increase the growth and density of the areas. DWR
stressed that the strategies should be based on native or natural materials.
5. An Adaptive Management Plan (AMP) should be provided for the low growth/density areas and
the area that exhibits characteristics of an open water, rather than a wetland complex. After receipt
of the AMP, the Corps will coordinate the report with the IRT to allow for comments. At the
conclusion of the AMP comment period, a portion of the Year 4 Monitoring Credits may be
released, pending IRT approval.

0
RES submitted an Adaptive Management Plan in February 2020. Year 4 credits were released at
the end of March 2020 and RES submitted a follow-up memo for the work completed in April
2020.
Thank you,

Arrington Bridge III Wetland Mitigation Site • USGS HUC 03020201
Year 5 Monitoring Report• Wayne County, North Carolina • September 2020
1 PROJECT GOALS, BACKGROUND AND ATTRIBUTES
1.1 Location and Setting
The Arrington Bridge III Wetland Mitigation Project is located in Wayne County approximately three
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.
1.2 Project Goals and Objectives
The Arrington Bridge III Wetland Mitigation Project provides numerous 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 removal
through wetland areas, the conversion of active cattle pastures to forested wetlands, and improved
denitrification and nutrient uptake through wetland zones.
Runoff filtration
Benefit will be achieved through the restoration of buffer areas that will receive and filter runoff,
thereby reducing nutrients and sediment concentrations reaching water bodies downstream.
Benefits to Flood Attenuation
Water storage
Benefit will be achieved through the restoration of wetland areas which will infiltrate more water
during precipitation events than under current site conditions.
Improved groundwater
Benefit will be achieved through the increased storage of precipitation in wetland areas, ephemeral
recharge
depressions, and reconnection of existing floodplain. Greater storage of water will lead to improved
infiltration and groundwater recharge.
Benefits Related to Ecological Processes
Restoration of habitats
Benefit will be achieved by restoring riparian wetland habitat to appropriate bottomland hardwood
ecosystem.

1.3.1 Wetland Restoration Type and Approach
The Arrington Bridge III Wetland Mitigation project provides 32.51 wetland mitigation units through
a combination of Wetland Restoration and two levels of Wetland Enhancement. The existing pasture
areas on the Site are treated 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 was put in place for 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 place for the lower -uplift wetland
enhancement areas, which are primarily along the north side of the main ditch. Both levels of Wetland
Enhancement were treated by enhancing the hydrology and providing long-term protection. This was
accomplished by filling the ditches across the site to raise the water table and restore a more natural
drainage pattern. Additionally, the pond was backfilled with the adjacent spoil pile and planted with
trees and a permanent seed mix. Although this was restored to a wetland, it receives Enhancement
credits at a ratio of 3:1 because the pond was already a jurisdictional feature.
1.3.1.1 Wetland 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 was removed and stabilized to restore the natural flow
pattern, and the pond was backfilled with the adjacent spoil pile;
• Areas of cut and fill were re -graded to create a continuous bottomland wetland system.
Plugging ditches and main channelized drainage feature
Plugging of the main feature and side ditches was accomplished through a combination of backfilling
and the construction of ditch plugs throughout the easement area. Approximately 8,600 linear feet of
open ditch was backfilled within the easement boundary. Ditches are filled, compacted, and graded to
the adjacent floodplain elevation. Typical ditch plugs are 20 feet wide and extend above the top of the
ditch bank elevation a minimum of 6 inches. Plugs are constructed of compacted 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 is graded to the existing ditch elevation.
When possible, ditch plugs are constructed using excavated material from the restoration and
construction of wetland pools.
Fill Removal, Pond Backfill, and LCgrading o fsite
Disturbed soils underlain by hydric soils (as described in the soils report) were graded to allow for a
more natural 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 three feet of elevation difference across the site.
Several decades of agricultural management and mining operations has eliminated microtopography

Arrington Bridge III Wetland Mitigation Site • USGS HUC 03020201
Year 5 Monitoring Report• Wayne County, North Carolina • September 2020
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 included large areas in a lower landscape position located adjacent to visible borrow
pits. The soils in these areas had variable textures that were exhibiting hydric indicators. All of this area
was in pasture and being grazed by cattle. One excavated pond is backfilled 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 was disked to break up the plow layer, increase
surface roughness, and promote infiltration.
1.3.1.2 Proposed 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. The ditch system was mostly in place. The restoration plan
for the site consisted of filling and stabilizing ditches, 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 lengthens wetland 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
1.4 Project History, Mitigation Bank Establishment, Contacts and Attribute Data
1.4.1 Project History
The Arrington Bridge III Wetland Mitigation Site was restored by EBX Neuse I, LLC (EBX). EBX is
an entity 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.
1.4.2 Project 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 m12). 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.

2 SUCCESS CRITERIA
The success criteria for the Arrington Bridge III Site follows accepted and approved success criteria
presented in the North Carolina Wetland Mitigation Guidelines and subsequent agency guidance.
Specific success criteria components are presented below.
2.1 Wetland Success Criteria
2.1.1 Wetland Hydrology Criteria
The Natural Resources Conservation Service (MRCS) 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 is compared to reference wetland gauge data 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 year monitoring period, then monitoring may be extended, remedial actions may be
undertaken, or the limits of wetland restoration will be determined.
2.2 Vegetation Success Criteria
Specific and measurable success criteria for plant density within the wetland areas on the site follows
IRT Guidance. Vegetation monitoring plots are a minimum of 0.02 acres in size, and cover a minimum
of two percent of the planted area. Vegetation monitoring occurs annually 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 is the 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 is the survival of 210 trees per acre at the end of
Year 7 of the monitoring period.
Survival is determined at the plot level, not averaged at the site level. No areas are planted with more
than 50 percent of one species comprising the total composition. In addition, planted vegetation should
show a general 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.
2.3 Scheduling/Reporting
The Bank Sponsor follows the 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

Arrington Bridge III Wetland Mitigation Site • USGS HUC 03020201
Year 5 Monitoring Report• Wayne County, North Carolina • September 2020
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
is implemented 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.
3 MONITORING PLAN
Annual monitoring data is reported using the IRT monitoring template. The monitoring report provides
a project data chronology that facilitates an understanding of project status and trends, research
purposes, and assists in decision making regarding project close-out. The success criteria for the
Arrington Bridge III site follows current 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.

Quarterly visual assessments
3.1 Visual Assessment Monitoring
Visual monitoring of all mitigation areas is conducted a minimum of twice per monitoring year by
qualified individuals. The visual assessments include vegetation density, vigor, invasive species, and
easement encroachments. Digital images are taken at fixed representative locations to record each
monitoring event, as well as any noted problem areas or areas of concern. Results of visual monitoring
are presented in a plan view exhibit with a brief description of problem areas and digital images.
Photographs are used 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.
3.2 Vegetation
Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover 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 occurs each year during the monitoring
period. Invasive and noxious species are monitored and controlled so that none become dominant or

Arrington Bridge III Wetland Mitigation Site • USGS HUC 03020201
Year 5 Monitoring Report• Wayne County, North Carolina • September 2020
alter the desired community structure of the site. If necessary, RES will develop a species -specific
control plan. Invasive and noxious species are monitored 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.
4 MAINTENANCE 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.
4.1 Wetlands
Any wetland 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 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 repair an area, a proposed
work plan will be submitted for remediation.
4.2 Vegetation
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 a vegetation 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
will be submitted for remediation.
5 MONITORING YEAR 5 (MY5)
The Arrington Bridge III Mitigation Site Year 5 monitoring activities were performed throughout
2020 with the most recent activity at the end of August 2020. All required Year 5 monitoring data is
present below and in the appendices. Data presented shows the site has remained stable throughout
Year 5 and in general is on track to meeting vegetation and hydrology interim success criteria. RES
performed a supplemental planting in April 2020 which included planting about 2,700 whips and
livestakes in areas that were not meeting success criteria in Year 4.
5.1 Year 5 Data Collection
5.1.1 Hydrology
Wetland hydrology is monitored with fifteen automatic 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 also installed to document
rainfall events. Monitoring Year 5 wetland hydrology gauge data is documented in Table 9, Appendix
B. Year 5 wetland hydrology data show the site is performing as planned and is trending toward targeted

Arrington Bridge III Wetland Mitigation Site • USGS HUC 03020201
Year 5 Monitoring Report• Wayne County, North Carolina • September 2020
wetland hydroperiods. During Year 5 wetland hydrology was monitored through August 27, 2020. All
15 wetland hydrology gauges met the hydrology success criteria of remaining continuously within 12
inches of the soil surface for at least eight percent of the growing season (eight percent is approximately
21 days). Hydroperiods ranged from 13% to 67%. Recorded rainfall data shows the site was below or
within normal limits for six months out of the sampled time. During February, April, May, June, and
August the site recorded above average rainfall (Table 8, Appendix B).
5.1.2 Vegetation
Vegetation monitoring occurred on August 27, 2020. Twenty-five of the 27 vegetation plots exceeded
the interim success criteria, 260 stems per acre, in Year 5. Planted stems per acre ranged from 202 to
1,052 with a mean of 567. Total stems per acre ranged from 202 to 4,897 with a mean of 851. The
average planted stem height was 5.1 feet. Vegetation Plot 6 and 7 did not meet the interim success.
Vegetation Plot 6 was two stems short and Vegetation Plot 7 was one stem short.
RES supplemental planted about 7.10 acres with 2,700 stems in April 2020. The planting occurred in
areas that exhibited open water/marsh characteristics. Visual assessments in Year 5 show that the
planting was overall successful, specifically the livestake species and the bald cypress/green ashes. RES
plans to perform an additional supplemental planting this winter, in and around Plots 6 and 7, and the
open water areas near Plot 4 and Plot 10 where the last supplemental planting was not as successful.
5.1.3 Photo Documentation
Permanent photo point locations are established at each vegetation plot by RES' staff. Any additional
problem areas or areas of concern will also be documented with a digital photograph during monitoring
activities. Digital photographs of the site's condition and vegetation plots can be found in Appendix B.
5.2 Adaptive Management
RES performed a supplemental planting in April 2020, in areas of prolonged inundation and poor tree
survival. RES performed stick plantings of bald cypress, green ash, black willow, water tupelo, and
buttonbush. Overall, the supplemental planting was successful. RES plans to plant additional trees this
winter in and around Plots 6 and 7, and the open water areas near Plot 4 and Plot 10. This supplemental
planting will total around 1.75 acres. Photos of the April 2020 supplemental planting are in Appendix
B and Additional information about the adaptive management work can be found in Appendix D and
Appendix A.

RE: Arrington Bridge III — Year 4 Monitoring Adaptive Management Plan
Dear Sam,
During Year 4 (2019) monitoring activities, RES documented an approximately 7.10 acre -area of low stem
density/poor growth of planted stems (approximately 24 perecent of the restoration area). Per the comment
letter we received on December 19, 2019, RES is providing this adaptative management plan to address the
low stem density/poor growth problem.
Comment: An Adaptive Management Plan (AMP) should be provided for the low growth/density areas
and the area that exhibits characteristics of open water, rather than a wetland complex.
Plan: RES plans on addressing the low stem density/poor growth problem by replanting the areas using
species and planting methods that are known to be successful in standing water. The areas onsite that are
exhibiting the low stem density/poor growth have surface water up to 18 inches deep present year-round.
Table 1 below outlines the species and amount of trees RES will plant. RES plans on planting 1,400 whips
and 1,300 livestakes/poles which represent about 380 stems per acre, and 2,700 trees total.

A combination of livestake approaches will be used. Three -foot -tall livestakes will be inserted directly into
the soil, ensuring some buds remain above the water level. Additionally, livestake poles that are six feet in
length will be planted in the deepest pool onsite, near VP 11. Planters will ensure buds remain above the
water level and the poles will discourage use of the open water by waterfowl.

Whips (two- to four -foot -long bareroot trees) will be prepped before planting by removing the lateral roots
and trimming the tap root down to nine inches before they are stick planted directly into the soil by pushing
them into the ground up to their root collar. The stick planting method outlined in the "Riparian & Wetland
Tree Planting Pocket Guide For North Carolina 3rd Edition" will be followed. This method works best
where soil is saturated and likely to remain saturated throughout the growing season. Stanturf et al, explains
that the trimming of the root system allows the tree to quickly begin growing a water -adapted root system
upon re -growth. Trees that are not trimmed will drain a large amount of energy shedding their old root
system before developing one better for standing water. Additionally, planting without a hole gives the
stems better contact with the soil around them and reduces the chances of the stems floating out of the soil.
RES plans to perform the replanting by the beginning of the 2020 growing season. Once work is completed,
RES will provide written notification to the IRT along with photo documentation to inform work has been
completed. A map is attached to show the areas that will be replanted. RES plans to keep the existing
vegetative success criteria (260 stems per acre by Year 5 and 210 stems per acre by Year 7) and will monitor
vegetation in MY6 to capture an extra year of data.

RE: Arrington Bridge I I I — Year 4 Monitoring Adaptive Management: Work Completed
Dear Ms. Dailey,
In response to problem areas identified in the Arrington Bridge III Year 4 Monitoring Report and
the Year 4 Adaptive Management Plan, RES performed and completed adaptive management
work in early April 2020. The work included planting whips and livestakes in the inundated, low
stem density areas. Photographs from the effort are included below (Figures 1 & 2). More
information about the work is detailed in the Adaptive Management Plan submitted on February
11, 2020, and accounted below:
