1.0 Introduction
Wildlands Holdings VI, LLC ("Sponsor") proposes to develop the Folly Swamp Mitigation Site (Site) as the
first project under the Wildlands Pasquotank 05 Umbrella Mitigation Bank ("bank"). Wildlands Holdings VI,
LLC is wholly owned by Wildlands Engineering, Inc.
The Folly Swamp Mitigation Site (Site) is in northern Gates County approximately 30 miles northwest of
Elizabeth City, NC and four miles north of Sunbury, NC (Figure 1). The project is located within the
Pasquotank River Basin Hydrologic Unit Code (HUC) 03010205010010 and NC Division of Water Resources
(DWR) Subbasin 03-01-50. The site was selected to provide stream mitigation credits in the Pasquotank
Basin 03010205 (Pasquotank 05) (Figure 2). The project involves the restoration of approximately 12,000
linear feet (LF) of incised and straightened streams. Restoration of these reaches will provide 12,809
stream mitigation credits (SMUs). The Site will be protected by a 50-acre conservation easement. The Site
Protection Instrument outlining the proposed easement is provided in Appendix 1.

2.0 Basin Characterization and Site Selection
The Site is in the Pasquotank 05 Basin, the DWR Subbasin 03-01-50, and the 03010205010010 14-digit
Hydrologic Unit (HU). There are no current local or state watershed plans associated specifically with this
subbasin. The Pasquotank 05 is dominated by forested land (59%) and agricultural land (40%), and 51% of
the stream buffers are non -forested. The major developed areas include Elizabeth City, Hertford, and
Edenton, and the main roadways consist of US-17, US-64, and US-158 (Figure 1). The Folly Swamp
Mitigation Site was selected because it would allow unavoidable impacts to Waters of the United States
within the service area to be mitigated appropriately and provide a means for the economic growth of this
region to continue while ensuring aquatic resources and water quality are maintained.
Very few water quality studies have been reported in the basin and subbasin. NCDMS published a River
Basin Restoration Priorities (RBRP) plan for the Pasquotank 05 in 2009. Among the goals listed in the 2009
RBRP that this mitigation project will address are:
• Develop additional Strategic Habitat Areas (SHAs) and coordinate data and methodology
improvements with other state and federal agencies
• Implement agricultural BMPs to reduce nonpoint source inputs to the estuary
• Protect, augment, and connect Natural Heritage Areas and other conservation lands
Also mentioned in the RBRP is that the watershed will benefit from stream restoration projects that
reestablish more natural pattern, hydrology, and habitat, especially in heavily ditched watersheds.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 1
The Site fits the need for meeting the watershed goals by augmenting and connecting Natural Heritage
Areas and reducing nonpoint source loading to the Albemarle Sound estuaries. Folly Swamp drains to the
Great Dismal Swamp National Wildlife Refuge and later the Pasquotank River and Albemarle Sound. The
project will essentially extend the protected area by 50 acres to the west of the Great Dismal Swamp.
Various areas of the Albemarle Sound on the 2018 303(d) list for pH, copper, and dioxin impairment. Also,
various segments of the Pasquotank River appear on the 2018 303(d) list for copper, dissolved oxygen, and
pH. The Site is a large source of nutrients and bacteria because it hosts a pasture -raised livestock operation
and is fertilized to promote growth of row crops. Visual inspections indicate that the primary stressors in
the Folly Swamp watershed come from row crop agriculture, lack of riparian buffers, and stream
channelization.
Restoration of streams and wetlands on the Site will directly and indirectly address stressors identified in
the RBRP by building stable stream banks and restoring a forested riparian buffer. The project will slow
surface runoff, increase retention times, provide shade to streams, and reconnect the streams to a
floodplain and riparian wetlands. This will reduce sediment and nutrient loads. Sediment and nutrient
loading contribute to the downstream production of chlorophyll a, which can lower dissolved oxygen
levels. In addition, restoration will provide and improve instream and terrestrial (riparian) habitats while
improving stream stability and overall hydrology.
3.0 Baseline and Existing Conditions
3.1 Watershed Conditions
The Site watershed (Table 2 and Figure 5) is situated in the rural countryside in Gates County between
Sunbury and Corapeake, NC, within the Middle Atlantic Coastal Plain. Site topography, as indicated on the
Sunbury, NC USGS 7.5-minute topographic quadrangles, includes mostly gently sloped areas with some
moderate topography along the upstream reaches. Generally, valleys onsite are unconfined and alluvial,
and valley slopes tend to flatten as elevation decreases. Channels closer to the Folly Swamp floodplain have
lower slopes than the headwater reaches.
To its confluence with Hamburg Ditch, Folly Swamp is a Class C, Swamp Waters stream suitable for aquatic
life and secondary recreation. The Hamburg Ditch, also known as Cross Canal, is within the Great Dismal
Swamp National Wildlife Refuge. Swamp Waters is a supplemental classification intended to recognize
those waters which have low velocities and other natural characteristics which are different from non -
swamp streams (i.e., naturally low dissolved oxygen and pH).
The watershed to the Site streams includes agriculture, forest, and some development, including dozens of
single-family homes, and relatively few commercial uses along NC 32. Most of the Site has row crops within
the riparian areas, while Greene Branch runs through pasture. There are no development pressures
indicting that the Site land use will change in the future. However, because Gates County serves as a
bedroom community for Suffolk, VA, it is conceivable that the Site could include a low -density development
in the distant future.
Based on a review of historical aerials, included in Appendix 4, the Site streams have had the same
approximate land use and configurations since at least 1950 with the following exceptions:
Folly Swamp was channelized between 1950 and 1959. Since that time, the drainage district travel
way (berm) has been on the left bank and the right floodplain has largely been cleared for
agricultural use.
• In the 1970's and 1980's, the following changes were made to the Site:
o Folly Swamp's left floodplain was converted to row crop fields.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 2
o A small area of forest was cleared at the downstream end of Barker Branch
0 105 acres of Greene Branch's watershed was converted from forest to agriculture.
o A field in the middle of Greene Branch was converted to agriculture, and Greene Branch
and its floodplain were ditched.

3.2 Landscape Characteristics
The Site is located within Ecoregion 63e — Mid -Atlantic Flatwoods. It occupies the middle portion of the
coastal plain. Soils formed in mostly Pleistocene -age clays and sands. Since the subsurface drainage is slow,
except near streams, artificial drainage is common.
The project is in the undivided Tertiary Yorktown Formation geologic region. The Yorktown Formation is
fossiliferous clay with varying amounts of fine-grained sand, bluish gray, shell material commonly
concentrated in lenses. The channel bed material reflects the local geology and consists of fine-grained
sand and silt.
The predominant Site floodplain soils on site are described in Table 3 below and depicted in Figure 7.

3.3 Project Resources
3.3.1 Existing Streams
In September 2019, Wildlands contracted an investigation of on -site jurisdictional waters of the U.S. within
the proposed project easement areas. Folly Swamp was deemed perennial and four unnamed tributaries
on the Site were deemed intermittent. These tributaries have been named Powell Branch, Morgan Branch,
Greene Branch, and Barker Branch by Wildlands. Jurisdictional stream features are shown on Figures 3, 3A
and 3B and supporting documentation is provided in Appendix 2.
The streams on the project site are small, first or second order streams with the exception of Folly Swamp.
Two Folly Swamp reaches comprise the upper end of the project area. Below this, Folly Swamp is a large,
channelized ditch maintained by the Gates County Drainage District #1 for drainage purposes and is not
suitable for stream mitigation. It should be noted that we are calling the mainstem Folly Swamp where it
will be restored, and Folly Ditch, as it is locally known, where not included in the mitigation project.
The Drainage District is in favor of restoring Folly Swamp at the upper end. Additional project streams enter
the Folly Ditch as it flows towards the Great Dismal Swamp, approximately 2.5 miles downstream from the
mainstem stream mitigation area.
Moving downstream from the Folly Swamp restoration reaches, approximately 1,500 feet from the
downstream terminus, Powell Branch is the first mitigation tributary to join the Folly Ditch. It flows from a
drainage area comprised of agricultural fields and forest into the southern bank of Folly Swamp. The stream
has widened in several locations and rills have formed as a result of agricultural runoff, resulting in
headcutting within Powell Branch. Morgan Branch is the next tributary downstream, flowing parallel to the
eastern side of NC 32 and entering the Folly Ditch from the north. Its headwaters are comprised of
silviculture and low density residential areas. The project reaches of Morgan Branch are within active
agricultural fields with a silviculture area along the downstream right bank.
The last reaches to join the Folly Ditch are Greene Branch and Barker Branch, approximately 2,100 and
2,500 feet downstream from Morgan Branch, respectively. Both Greene Branch and Barker Branch enter
the Folly Ditch from the south. Approximately 30 head of cattle graze along Greene Branch and have access
to the upper reach. A single strand of electrified wire keeps them out of the lower reach. Greene Branch's
headwaters have been diverted and the upper reach is an ephemeral low area in a forested setting.
Barker Branch is also a maintained ditch that flows through agricultural fields. Its lower left bank is adjacent
to the same cattle pasture shared by Greene Branch. The two branches are on opposite sides of a wetland
feature adjacent to the Folly Ditch.
Geomorphic surveys were conducted on Site streams to characterize their existing condition. Existing
streams and cross section locations are illustrated in Figure 2. NCDWR stream assessment forms are in
Appendix 3 and reach specific cross sections and geomorphic summaries are provided in Appendix 4.
Folly Swamp
Folly Swamp is a maintained ditch with instream substrate dominated by silt and sand. A pilot channel is
frequently present within the larger ditch. Early successional trees populate the streambanks. A sidecast
berm is present along much of the left bank and serves as a travel way for ditch maintenance. On the
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 4
downstream end, the berm directs high floods over the right bank toward the residential homes on Savage
Road. A perched culvert on this stream may function as an aquatic migration barrier. Stream function was
assessed on Folly Swamp using the North Carolina Stream Assessment Method (NCSAM) and found to be
Low due to deficiencies in flood flow, water quality, in -stream habitat, and poor vegetative bank cover.
Two cross sections were measured in the upper and lower reach. The reaches are separated by another
maintained ditch from the north. This ditch is referred to in the project as Jordan Branch. As presented in
the Section 3.3.2 below, Jordan Branch, within its banks, has been determined to be a jurisdictional
wetland.

Powell Branch is a first order tributary to the Folly Ditch. A sidecast berm is also present along most of the
upper portion of the reach and the stream has been channelized downstream of the wood line. In the
channelized section, a 4-foot high berm parallels the left bank and a maintenance travel way parallels right
bank. Powell Branch has sections of vertical, eroding banks and active rilling where agricultural field runoff
concentrates down the stream banks. The stream is deeply incised with a bank height ratio of 4.4. Stream
function was assessed on Powell Branch using NC SAM and found to be Low due to deficiencies in epifaunal
substrate, embeddedness, low bank stability and stream -side habitat, and poor vegetative bank cover.

Morgan Branch is a first order tributary to the Folly Ditch located just east of NC-32. Morgan Branch is
incised with a bank height ratio of 3.8 and is eroded in areas where the stream banks are steep. Two active
drain tiles are present in the upstream floodplain of Morgan Branch, indicating that the floodplain is being
hydraulically bypassed. The last 540 feet of Morgan Branch's left floodplain is wet and frequently bush
hogged while the right floodplain is a planted pine forest with a Chinese privet understory. Stream function
was assessed on Morgan Branch using NCSAM and found to be Low due to deficiencies in flood flow,
stream stability, water quality, in -stream and stream -side habitat, and poor vegetative bank cover.

The upper end of Greene Branch is poorly defined. An upslope ditch which parallels Greene Branch and a
diversion channel at the property boundary diverts much of the overland flow that would naturally reach
this section of Greene Branch. Wildlands installed a weir and flow gage on the diversion channel on March
15, 2019 and measured flow through April 10, 2019. The gage measured consistent ditch flow on all 26
days.
Approximately midway between the diverted headwaters and Greene Branch's confluence with the Folly
Ditch, is a ditched drainage that has been determined to be a linear wetland. This drainage is referred to as
Pollo Branch in the project. It drains an area with four chicken -rearing houses.
Downstream of this area, Greene Branch is channelized with a deeply set, constructed U-shaped channel.
Erosion is present at the toe of the channel, but largely obscured by the presence of thick vegetative
overgrowth above the deeply incised channel. Greene Branch is incised with a bank height ratio of 1.8. A
perched culvert on this stream may function as an aquatic migration barrier. Stream function was assessed
on Greene Branch using NCSAM and found to be Low due to deficiencies in water quality, in -stream and
stream -side habitat, and poor vegetative bank cover.
Approximately 20 cattle and 50 sheep have access to areas with the proposed conservation easement
along Greene Branch. As evidenced in the photo below, they regularly disturb the herbaceous vegetation
and soil structure along upper Greene Branch. Excluding them from the conservation easement area will
allow the vegetation and soil structure to re-establish, as well as reduce nutrient and fecal coliform loading
to the Folly Ditch.

Barker Branch emanates as a shallow channel from a wooded area and flows along the east side of an
agricultural field and becomes intermittent as it leaves the treeline and received from a ditch from the east.
Barker Branch becomes incised and entrenched below an active headcut just 200 feet downstream from its
jurisdictional start and continues in that condition to the stream's confluence with the Folly Ditch. Stream
function was assessed on Barker Branch using NCSAM and found to be Low due to deficiencies in flood
flow, stream stability, water quality, in -stream and stream -side habitat, and poor vegetative bank cover.

In September 2019, Wildlands contracted an investigation by Soil & Environmental Consultants, PA (S&EC)
of on -site jurisdictional waters of the U.S. within the proposed project easement areas. Jurisdictional areas
were delineated using the US Army Corps of Engineers (USACE) Routine On -Site Determination Method.
This method is defined by the 1987 Corps of Engineers Wetlands Delineation Manual and the subsequent
Atlantic and Gulf Coastal Plain Regional Supplement. All jurisdictional waters of the U.S. were located by
sub -meter GPS. Wetland determination forms representative of on -site jurisdictional areas as well as non -
jurisdictional upland areas are included in Appendix 2.
The wetland delineation was field reviewed by USACE staff on November 6, 2019 and PJD application was
submitted on November 18, 2019. There are five jurisdictional wetland features located on -site (labeled
Wetland A — Wetland E). These wetland features are classified as headwater forests, bottomland hardwood
forest, or seeps.
Wetlands are infrequent along the project streams. Jurisdictional wetlands are present along Folly Swamp
in three locations:
• on the left bank just upstream from the Jordan Branch confluence
• on the left bank downstream from NC32 extending to Morgan Branch
• on the right bank between lower Greene Branch and lower Barker Branch

Pollo Branch and lower Jordan Branch were also mapped as jurisdictional wetlands. Pollo Branch is a linear
wetland that drains from the west to the middle area of Greene Branch. Jordan Branch is a linear wetland
ditch that drains from the north to the middle of Folly Swamp and demarcates the break between Reach 1
and 2.
These features exhibit a high water table, pockets of shallow inundation, saturation within the upper 12
inches of the soil profile, a low chroma matrix, and hydrophytic vegetation.
3.3.3 Existing Vegetation
Vegetation along the Site streams is fairly consistent, including species such as sweetgum (Liquidambar
styraciflua), red maple (Acer rubrum), smooth sumac (Rhus glabra), elderberry (Sambucus spp.), pokeberry
(Phytolacca americana), dog fennel (Eupatorium capillifolium), loblolly pine (Pinus taeda), Chinese privet
(Ligustrum sinense), blackberry (Rubus spp.), and various grasses. Chinese privet (latin name) is present
throughout the Site but is only dense at the downstream ends of Morgan Branch and Powell Branch.
3.4 Overall Functional Uplift Potential
The primary stressors on site are incision and entrenchment from channelization and a lack of riparian
buffers. These stressors led to Low NCSAM scores. Without intervention, Folly Swamp and its tributaries
will continue to widen, which will further disconnect riparian wetland hydrology. Ultimately, functional
uplift for this Site is linked to improvement in and maintenance of hydrologic connectivity between streams
and riparian wetlands. Additionally, establishing a riparian buffer will protect and enhance this connectivity.
Functional uplift for the site will be achieved through the following:
• Restoring degraded stream channels to reduce erosion and reconnect streams to riparian wetlands
to restore hydrologic connection.
• Eliminating bank erosion and associated pollutants.
• Planting riparian buffers to shade streams, help stabilize streams, and promote woody debris in
system.
• Fencing out livestock.
• Protecting the site with a conservation easement.
These project components are described in Section 5 in terms of goals, objectives, and outcomes for the
project and in greater detail in Section 6 as the project site mitigation plan.
3.5 Site Constraints to Functional Uplift
The following potential Site constraints have been identified and will be addressed as part of this project.
Establishing vegetation on Priority Level 2 stream restoration (Folly Swamp and Powell Branch) has been
challenging on other projects. Wildlands has prepared a Vegetation and Planting Plan (Section 3.7) to
address this potential constraint. Priority Level 2 restoration may have a limited floodplain on some
projects. As described in Section 6.6 Project Implementation, Wildlands will construct floodplains that are
at least 4 times bankfull width and have a slope that is flatter than 5:1. Groundwater wells will be placed on
the floodplains of each Site stream to assess the effect of restoration on local hydrology. Another
constraint is that some of the smaller drainage areas may have low flow. Wildlands has monitored these
channels and expects that 30 days of continuous flow annually will be achievable. Last, beaver may enter
the Site streams because they are known to be present on lower Folly Ditch, near the Great Dismal Swamp.
Wildlands will contract with the U.S. Department of Agriculture (USDA) to remove beavers if they become a
problem on the Site (i.e., within the conservation easement areas).

A pedestrian survey of the site conducted on October 29, 2019 indicated that suitable habitat was present
for the Red -Cockaded Woodpecker and the NLEB. No suitable habitat was found for the American alligator.
No federally threatened or endangered individuals were observed.
4.1.1 Biological Conclusion
A public notice was issued for comment to Federal, State, and local agencies and officials, including the
USFWS, NC Wildlife Resources Commission (NCWRC), and the State Historic Preservation Officer (SHPO) on
August 22, 2019. Wildlands also submitted scoping letters to these agencies on November 22, 2019 that
included investigation into the presence of threatened and endangered species on Site protected under
The Endangered Species Act of 1973, as well as any historical resources protected under The National
Historic Preservation Act of 1966.
USFWS's biological conclusion for the Site is that the project "is expected to have minimal adverse impacts
to fish and wildlife resources". USFWS requested that USACE submit a Situation three pursuant to the
SLPOES agreement to USFWS to satisfy the remaining requirements of section 7 (a)(2) of the ESA. NCWRC
did not comment.
SHPO concluded that the project will not affect historic resources

4.2 FEMA Floodplain Compliance and Hydrologic Trespass
Folly Swamp, through the Site, is mapped as FEMA Zone AE with a regulatory floodway. Wildlands has
preliminarily modeled the design conditions and is seeking to achieve a No -Rise condition. However,
because the stream is being relocated outside of the effective regulatory floodway, a CLOMR may be
required while meeting the expectation of no rises in modeled water surface elevations. If a CLOMR is
required, a LOMR will be prepared after construction is complete. A floodplain development permit will be
obtained as part of the mitigation project. The other project reaches, Powell Branch, Morgan Branch,
Greene Branch, and Barker Branch are primarily mapped Zone X and are not modeled streams. However,
the downstream extents of each tributary are located within the flood fringe of Folly Swamp. We
anticipate any requirements around the tributaries will be addressed locally with Gates County through the
floodplain development permit.
4.3 401/404
Five jurisdictional wetlands are located in the project area (see Section 3.3 — Project Resources). The
existing jurisdictional wetlands appear in Figure 8A and 8B. The proposed stream channels are routed away
from these features when possible. However, the proposed stream channels often will impact the wetlands
when there is no alternative. Any wetlands within the conservation easement will be denoted in the final
construction plans on the Erosion and Sediment Control plan and detail plan sheets, as well as in the
project specifications. Floodplain grading will be considered a temporary impact to wetlands if final grade is
within one foot of existing grade. Some wetland resources will be converted to stream resources. Wildlands
expects a net gain of wetland area, as construction of the new channels will fill most of the old channels to
the elevation of the existing wetlands, creating a wider overall floodplain and riparian wetland area.
Table 11 estimates the anticipated impacts to wetland areas on this project. Final impacts will be provided
in the Pre -Construction Notification (PCN), after proposed floodplain grading has been completed, and will
more accurately quantify these data. The numbers below reflect a conservative estimate of potential
impacts. Of the five individually mapped wetlands, five may have temporary impacts, and four may have
permanent impacts. Wetland impacts will be scrutinized much more closely in the PCN application.

5.0 Mitigation Site Goals and Objectives
The project will improve stream functions as described in Section 5 through stream and wetland
restoration and riparian buffer re -vegetation. Project goals are desired project outcomes and are verifiable
through measurement and/or visual assessment. Objectives are activities that will result in the
accomplishment of goals. The project will be monitored after construction to evaluate performance as
described in Section 10 of this report. The project goals and related objectives are described in Table 12.

6.0 Design Approach and Mitigation Work Plan
6.1 Design Approach Overview
The design approach for this Site was developed to meet the goals and objectives described in Section 5
which were formulated based on the potential for uplift described in Section 3.4. The design is also
intended to provide the expected outcomes in Section 5, though these are not tied to performance criteria.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 13
The project streams planned for restoration will be reconnected with an active floodplain and the channels
will be reconstructed with stable dimension, pattern, and profile that will transport the water and sediment
delivered to the system. Exceptions are in two instances when the Coastal Plain headwater approach
(USACE and DENR, 2005) will be implemented. In this case the channel will have floodplain access but a
single -thread channel with meandering pattern will not be constructed. Where buffer restoration or
enhancement is needed, the adjacent floodplains and riparian wetlands will be planted with native tree
species. Instream structures will be built in the channels to help maintain stable channel morphology and
improve aquatic habitat. The Site will be protected in perpetuity by a conservation easement.
The design approach for this Site employed a combination of analog and analytical approaches for stream
restoration. Reference reaches were identified to serve as an acceptable range for design parameters.
Channels were sized based on design discharge hydrologic analysis and empirical approaches including
applying regional curve equations. Designs were then verified and/or modified based on a sediment
transport analysis. This approach has been used on successful Inner Coastal Plain restoration projects (e.g.,
Falling Creek and Grantham Branch Mitigation Sites) and is appropriate for the goals and objectives for this
Site.
6.2 Reference Streams
Reference streams provide geomorphic parameters of a stable system, which can be used to inform design
of stable channels of similar stream types in similar landscapes and watersheds. Eight reference reaches
were identified for this Site (Figure 9) and used to support the design of Folly Swamp and its tributaries.
These reference reaches were chosen because of their similarities to the Site streams including drainage
area, valley slope, morphology, and bed material. All but three of the reference reaches are located either
within the Yorktown Formation and Mid -Atlantic Flatwoods ecoregion that also contain the Site. The Hell
Swamp and Watts mitigation projects serve as reference reaches for the Coastal Plain headwater approach.
They are located slightly to the east in Quaternary deposits and the Pamlico Lowlands and Tidal Marshes
(Ecoregion 63b). It appears that the geologic and ecoregion settings are relatively similar to the Site.
Geomorphic parameters for most of these reference reaches are summarized in Appendix 4; the local sites
used only for discharge are not included in Appendix 4. The references to be used for the specific streams
are shown in Table 13. A description of each reference reach is included in Table 13.

6.2.1 Acorn Hill Creek
In search of reference sites, Wildlands investigated Acorn Hill Creek, which is approximately 3 miles south
of the Greene and Barker Branch area of the Site. Acorn Hill Creek is east of Sunbury and south of US 158.
Like the Site, it is underlain by Yorktown formation. The land use hasn't changed since 1993 except for
limited logging activity in headwater areas outside of the identified reference reaches. Four subwatersheds
ranging in size from approximately 170 acres to 670 acres provided several examples of Site -similar
drainage areas with well -formed channels.
It should be noted that the soils at Acorn Hill are primarily Nawney loam, Bladen loam, and lesser Pantego
fine sandy loam. These are largely the same as the Site soils.
Wildlands conducted four detailed geomorphic surveys and additional cross sections of mostly single -
thread channels within the Acorn Hill system. These includes the North Fork of Acorn Hill Creek (0.27
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 15
square mile drainage area and 0.31% channel slope), the South Fork of Acorn Hill Creek (0.7 square mile
drainage area and 0.13% channel slope), Outland Branch (0.81 square mile drainage area and 0.70%
channel slope), and the Acorn Hill Creek (1.05+ square mile drainage area and 0.11% channel slope).
Cross sections were measured at several other locations in the Acorn Hill Creek system that were reference
quality. The Acorn Hill reference reaches served to define the lower end of the reference reach curve. They
also served to develop dimension and profile parameters for the Site streams. Tree roots formed natural
grade control features on these references. The drop height over these roots informed how grade is
dropped on low -slope Site reaches including Folly Swamp and Powell Branch.
6.3 Design Discharge Analysis
Multiple methods were used to develop bankfull discharge estimates for each of the project restoration
reaches: the NC Rural Coastal Plain Regional Curve (Doll et al., 2003), the EcoScience Coastal Plain Curve
(Sweet and Geratz, 2003), Wildlands Regional Flood Frequency Analysis, a site -specific reference reach
curve, and data from previous successful design projects. The resulting values were compared and
concurrence between the estimates was evaluated. The purpose of using multiple methods to estimate
design discharge is to eliminate reliance on a single method as the basis of channel design. However, the
methods commonly produce significantly different results so professional judgement must be used to
select the final design discharge for each restoration reach. Each of the methods used to estimate
discharge are described below and the results of the analysis are summarized in Table 14 and illustrated in
Figure 11.
6.3.1 Published Regional Curve Data
The NC Rural Coastal Plain Regional Curve published by Doll et al. in 2003 and the EcoScience Coastal Plain
Curve were used to estimate discharge based on the drainage area of each design reach. The discharge
values derived from these regional curves were in the same range as those derived from the site -specific
reference reach curve and consistently lower than the figures produced by the Wildlands Regional Flood
Frequency Analysis.
6.3.2 Regional Flood Frequency Analysis
Wildlands developed a regional flood frequency analysis relation for the NC Coastal Plain region based on
methodology described in the 2009 USGS publication Magnitude and Frequency of Rural Floods in the
Southeastern United States, through 2006 (Weaver et al., 2009). Of the 103 stations referenced in the
publication, 12 stations with drainage areas ranging from 0.28 to 7.63 square miles were used in the
development of the tool. The applicable stations were selected based on several criteria such as geographic
region, drainage area, watershed characteristics, and dates of data collection. Peak flow data from the 12
USGS stream stations used for the creation of this relation were analyzed for homogeneity using Hosking
and Wallis (1993) heterogeneity statistics in the statistics program R®. All stations were found to be
acceptably homogeneous. The included gages are as follows:
• USGS 02227422 —
Crooked Creek Tributary near Bristol, GA (DA = 0.28 mil)
• USGS 0209173190 — Unnamed Tributary to Sand Run near Lizzie, NC (DA = 0.57 mil)
• USGS 02227990 —
Satilla River Tributary 2 at Atkinson, GA (DA = 0.67 mil)
• USGS 02169960 —
Lake Marion Tributary near Vance, SC (DA = 2.12 mil)
• USGS 01668300 —
Farmers Hall Creek near Champlain, VA (DA = 2.18 mil)
• USGS 021355013
— Davis Branch near Sumter, SC (DA = 2.50 mil)
• USGS 02136361 —
Turkey Creak near Maryville, SC (DA = 4.25 mil)
• USGS 021720725
— Canton Creek near Moncks Corner, SC (DA = 4.82 mil)
• USGS 02148090 —
Swift Creek near Camden, SC (DA = 4.90 mil)
• USGS 02130800 —
Backswamp near Darlington, SC (DA = 6.22 mil)
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan

USGS 01661800— Bush Mill Stream near Heathsvi Ile, VA (DA = 6.77 mil)
USGS 02102908— Flat Creek near Iverness, NC (DA = 7.63 mil)
The data from these 12 gage stations were used to develop flood frequency curves for the 1-year, 1.2-year,
1.5-year, 1.8-year, and 2-year recurrence interval discharges. These relations can be used to estimate
discharge of those recurrence intervals for ungaged streams in the same hydrologic region and were solved
to determine the discharge of each project reach with the drainage area as the input. The Wildlands
regional flood frequency analysis produced discharge values that were consistently higher than the other
two primary discharge analysis methods.
6.3.3 Site Specific Reference Reach Curve
A total of 14 reference reaches were identified for this project (Section 6.2) and all but the two Coastal
Plain Headwater reaches were used to develop a Site -Specific Reference Reach Curve. Each reference reach
was surveyed to develop information for analyzing drainage area -discharge relationships. Some were only
used for plotting on a Site -specific reference curve for discharge and did not include development of design
parameters for pattern or profile; these channels do not appear in the Appendix reference reach table.
Stable cross -sectional dimensions and channel slopes were used to compute a bankfull discharge with the
Manning's equation for each reference reach. The resulting discharge values were plotted against drainage
area to make a Site -specific reference curve. The discharge values derived from the resulting curve were
consistently lower than the published Coastal Plain regional curve data and the Wildlands regional flood
frequency analysis.
6.3.4 Design Discharge Analysis Summary
The results of the design discharge analysis provided a range of discharge values. There was convergence
between the estimates derived from the NC Rural Coastal Plain Regional Curve and the Wildlands regional
flood frequency analysis 1.2-year discharges for Folly Swamp and Powell Branch. The results of the two
methods had an average variation of 9% over the design reaches. On the other hand, the Wildlands
regional flood frequency analysis returned values for the 1.2-year event that were consistently higher than
the other two primary methods for the other design streams (Morgan Branch, Greene Branch, and Barker
Branch).
For Morgan Branch, Greene Branch, and Barker Branch, there was convergence between the estimates
derived from the NC Rural Coastal Plain Regional Curve and the site -specific reference reach curve. On
average, these two methods differed by 19% over the four design reaches.
Wildlands ultimately selected a weighted design discharge approach by using 33% weight from the
reference reach curve, 27% weight from the NC Rural Coastal Plain Regional Curve, 20% weight from the
1.2-year flood frequency analysis, 13% weight from the EcoScience Coastal Plain Curve, and 7% weight
from the 1.5-year flood frequency analysis. The products of this weighted design discharge were 8-25%
above those of the reference reach curve.
Table 14 provides a summary of the discharge analysis. Figure 11 illustrates the design discharge data.

6.4 Design Channel Morphological Parameters
Reference reaches were a primary source of information to develop the pattern and profile design
parameters for the streams. Ranges of pattern parameters were developed within the reference reach
parameter ranges with some exceptions based on best professional judgement and knowledge from
previous projects. For example, radius of curvature ratio is kept above 1.9 on all reaches and meander
width ratio is kept above 2.9 in the moderately confined valleys of the Folly Swamp site. Wildlands has
found these minimum ratios to support stable geometry. For the B channel headwater reaches, channel
design did not follow the stream pattern ratios.
Reference ranges were also used to inform the design of the cross -sections on the streams. The streams
were designed with pool widths to be approximately 1.3 times the width of riffles to provide adequate
point bars and riffle pool transition zones. Designer experience was used for pool design as well. Pool
depths were designed to be a minimum of nearly 2.0 times deeper than riffles to provide habitat variation.
Cross-section parameters such as area, depth, and width were designed based on the design discharge and
stable bank slopes. The width to depth ratio was increased beyond some of the reference parameters to
provide stable bank slopes prior to the establishment of a vegetated streambank. A summary of
morphological parameters for several Site reaches, including Folly Swamp R1 and R2, Powell Branch,
Morgan Branch, Greene Branch R2, and Barker Branch R2 are listed in Tables 15, 16, and 17. Complete
morphological tables for existing, reference, and proposed conditions are provided in Appendix 4.

6.5 Sediment Transport Analysis
Results of sediment transport analyses are presented in Table 18 below. The primary consideration for
sediment transport in this project is transport capacity. This is measured by stream power. Shear stress is
not a factor because the sand bed streams will mobilize all particles in a sediment -moving discharge event.
Furthermore, the existing streams, for the most part, are not aggrading or degrading, though some are
widening, and lower Greene and Barker Branches are degrading. Wildlands conducted an analysis to see if
changes to stream power might affect the channel condition. If a problem is identified, further grade
control or bank revetment measures could be implemented.
On -site streams were visually inspected numerous times between 2018 and 2020 to qualitatively assess
bank erosion and aggradation and degradation within the channels. Site streams exhibit some evidence of
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 20
on -going fluvial erosion of streambanks and channel bottom. However, if streambank and bed erosion is
reduced through restoration and enhancement activities, this sediment load will be greatly reduced. The
restoration design will also more uniformly distribute stream power and shear stress in the channels.
Set in mostly flat valleys and channels, the Folly Swamp streams are not prone to degradation. As such, the
design will generally not include threshold structures to prevent headcuts from forming and migrating. One
exception is where reach slopes are steeper for channels to drop from a higher grade to the existing bed
grade. In those cases, threshold structures will include log sills, woody riffles that include gravel backfill,
and combinations of the two. Rock will be obtained from a Coastal Plain pea gravel pit that provides
material in the 2- to 6-inch diameter range. This material was used at the Falling Creek Mitigation Site in
Wayne County and is of suitable size and type to meet the requirements of the Site.
Another potential source of erosion is runoff from agricultural fields within the project area. Row crop
fields and cattle pasture deliver fine sediment that appears to be mostly transported by the existing
channels. With a planted riparian buffer, the potential for washload to the proposed streams will be
significantly reduced. Consequently, due to a decrease in potential sediment loading, lower stream power
in the design streams should not result in increased aggradation potential.
6.5.1 Competence Analysis
Competence analyses were performed during design for each of the restoration reaches by comparing
shear stress associated with the design bankfull discharge, proposed channel dimensions, and proposed
channel slopes. The analysis used standard equations based on a methodology using the Shields (1936)
curve and Andrews (1980) equation described by Rosgen (2001). The results of the analysis are shown in
Table 18.
One reach that warrants closer attention is Powell Branch Reach 2, where the channel is relatively steep as
it is dropped from a higher restored grade to existing grade in the Folly Ditch. Additional grade control and
bank revetments, such as brush toe, will be implemented here to prevent channel degradation and bank
erosion. Morgan Branch and Folly Swamp include similar short transitional zones, but the gradient change
is less significant than for Powell Branch.
6.5.2 Capacity Analysis
Table 18 lists the estimated design and existing stream power for each of the primary restoration stream
channels. The primary objective of calculating capacity was to note where design stream power varies
demonstrably from existing stream power and whether the existing conditions indicate a problem may
result. For example, if the existing stream is degrading and stream power increases, further degradation
may be expected.
As shown, stream power increases in Greene Branch Reach 2B and is relatively high in Powell Branch Reach
2. The increase in stream power in Greene Branch is not concerning because it is a relatively small increase;
however, the existing channel is degrading in this section. As a result, additional grade control and bank
revetments will be implemented in Greene Branch Reach 2B. As described above, Powell Branch Reach 2
will receive additional grade control and bank revetments. Finally, low stream power is not expected to be
an issue with the Site because the future bedload and washload are expected to be negligible.

6.6 Project Implementation
This section provides narrative detail on the restoration or enhancement approaches for each of the
project reaches. All project reaches will include the establishment of the following:
1. A conservation easement protecting the project from uses that would damage it.
2. A riparian buffer that consists of native hardwood species at a density to meet success criteria.
3. Livestock exclusion where applicable.
4. Invasive species treatment.
6.6.1 Folly Swamp Reaches 1 and 2
Folly Swamp will be restored beginning at the upstream property line and continuing through the
conservation easement to the downstream property line. At the upstream end of the project Folly Swamp
will be gradually raised with Priority Level 2 restoration. It is designed to have a shallow but wide floodplain
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 22
of at least five times bankfull width. As with all reaches, the highest floodplain elevation attainable will be
targeted. The terrace slopes will rise very gradually from the excavated floodplain such that the width from
existing ground to existing ground will be approximately 125 to 175 feet. The side cast berm along the
existing ditch will be removed. A new travel way will be reconstructed outside of the conservation
easement.
The restored stream will gently meander through an excavated valley, restoring pattern to the straightened
channel. The Folly Swamp design consists of a two -stage channel. A smaller pilot channel will thread
through a larger meandering channel. The pilot channel is designed to transport baseflow and the sediment
load carried at that stage. The larger meandering channel has a width -to -depth ratio of 19, which targets a
channel dimension similar to that at Acorn Hill Creek, a nearby reference stream system. Pools comprise
72% of the reach and are designed to be flat to allow for grade drops over log structures. Riffles, as in the
Acorn Hill reaches, are used sparingly in only the short downstream transitional section. Stream structures
are placed primarily for habitat formation and maintenance as there is low shear stress. Woody material
will be incorporated as much as possible to mimic conditions found in the Acorn Hill system.
Where grading is required to lower floodplain elevations topsoil will be stockpiled and combined into
subsurface soil to achieve final grades. Additionally, soil samples have been collected and analyzed, and
amendments will be added as necessary to achieve desirable pH and nutrient levels. Chicken litter is being
obtained and composted to be added to the Priority 2 cut areas. This will boost soil properties such as
organic matter, fertility, and water retention.
Floodplain slopes will have grades no steeper than 5:1 to reduce rilling before vegetation establishes and to
better stabilize soil structure. Stockpiled topsoil will be reapplied with the necessary soil amendments after
the final slopes are completed. Wildlands will work to establish temporary vegetation on these slopes as
quickly as possible to ensure erosion is limited. Section 6.7 includes details on how Wildlands will address
soil compaction.
The wetland (Wetland D, —0.67 acres) identified in the preliminary JD has been avoided as much as
possible. The proposed stream alignment is as far south as the property boundary allows, which brings the
restored channel through the narrower end of the wetland. A gage has been placed on the northern side of
the wetland, approximately halfway between where the cut slope begins and the conservation easement
boundary, to determine the project's effect on wetland hydrology. Additionally, it is expected that
wetlands will be created along the excavated floodplain.
In sum, except for livestock exclusion, the restoration proposed for Folly Swamp will meet the goals and
objectives outlined in Table 13 (Section 5).
6.6.2 Powell Branch
Powell Branch will be restored below the Savage Road culvert until its confluence with Folly Ditch. For the
first approximately 900 feet of Powell Branch, a functional floodplain will be constructed using a Priority Level
2 approach with an average depth of floodplain cut, relative to existing top of bank, of 2.6 feet. This approach
will be necessary because the proposed starting thalweg elevation cannot exceed the existing thalweg
elevation without creating increased backwater conditions that extend upstream to and past Savage Road.
To avoid potential adverse effects from floodplain cut, topsoil will be removed and stockpiled before further
excavation. The stockpiled topsoil will be reapplied and improved with soil amendments.
Priority Level 1 restoration will be implemented beyond the first 900 feet until the confluence with Folly
Ditch. The floodplain cut will be significantly reduced throughout this length of valley. To achieve the desired
floodplain width, the wooded area on lower Powell Branch, which is dominated by Chinese privet, will be
cleared and replanted.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 23
The vast majority of Powell Branch will have a wide floodplain of at least four times bankfull width.
Like Folly Swamp, Powell Branch has been designed with a two -stage channel. A smaller pilot channel will
thread through a larger meandering channel. The pilot channel is designed to transport baseflow and the
sediment load carried at that stage. The larger meandering channel has a width -to -depth ratio of 20, which
targets the channel dimension present at Acorn Hill Creek, a nearby reference stream system. The two -stage
Powell Branch channel transitions to a single stage channel approximately 370 feet from Folly Ditch. This
transition is necessitated by an increased channel slope which will result in increased stream velocities and
a reduced cross -sectional area will be required to carry the design bankfull discharge.
Except for livestock exclusion, the restoration proposed for Powell Branch will meet the goals and
objectives outlined in Table 13 (Section 5).
6.6.3 Morgan Branch
Morgan Branch will be initially restored with shallow Priority 2 restoration that uses a floodplain elevation
of approximately one foot below the existing ditch top of bank. This will allow for a wide floodplain, very
limited cut, and balanced earthwork. As such, the disturbance to the existing soil profiles will be minimal
and trees, with proposed soil amendments, should readily establish. By approximately 1,200 feet, Morgan
Branch will be at Priority 1 depth according to the existing top of bank. Priority 1 restoration then continues
for 2,100 feet.
The final 300 feet of the Morgan Branch design implements a steeper, Piedmont -like C channel to drop
gradient over three woody riffles and tie in the with deeper Folly Ditch.
The grading plan for Morgan Branch, to be completed while the draft mitigation plan is reviewed, will seek
to balance earthwork and promote drainage from the surrounding agricultural fields. The finished
floodplain will widen at a flat elevation initially and then taper at a 10:1 slope to existing grade.
Two drain tiles enter Morgan Branch at 700 and 1,600 feet into the restored alignment. Vernal pools will be
constructed to receive flow from the tiles. The vernal pools will then be drained to the proposed channel
with small channels.
Angled log sills and log sill with rootwads were used to serve as grade control. Brush toes and cover logs are
also used throughout the reach.
An existing wetland approaches the stream's right bank at the furthest downstream riffle in the vicinity of
stream station 435+00. A small amount of grading may be conducted to install a woody riffle along this
wetland, resulting in a temporary wetlands impact.
Except for livestock exclusion, the restoration proposed for Morgan Branch will meet the goals and
objectives outlined in Table 13 (Section 5).
6.6.4 Greene Branch
Upper Greene Branch is complicated by the fact that it is not fed by the drainage area expected based on
the surrounding topography. However, by installing a culvert at the upstream end and plugging the ditch
below the head of the proposed culvert, the natural drainage of upper Greene Branch will be reconstituted
and the riparian corridor will be restored using the Coastal Plain headwater valley approach.
Wildlands has an agreement in concept with the neighboring landowner to purchase a conservation
easement that will allow the culvert installation and ditch plugging. It will also restrict drainage alteration in
the 1.59 acres leading to the culvert. This will prevent any drainage modification that would undo the re-
establishment of the natural drainage pattern. Trees will not be planted on this 1.59 acres and farming will
continue.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 24
The Coastal Plain headwater design proposed for Greene Branch will utilize the existing hydrology of the
wooded valley to the greatest extent possible. An existing ditch within the adjacent open pasture that runs
parallel to the wooded valley will be filled and flow to the existing ditch will be rerouted to the low area of
the wooded valley. Necessary grading within this reach will include the creation of gentle swales to
hydraulically connect existing flow paths and low areas within the valley as well as connect the proposed
culvert, described above, to the valley. Where swales are proposed, woody structures will be added to
mimic the existing intertwined network of tree roots that serve as grade control and habitat structures.
Livestock will be excluded from the easement. The upper reach of Greene Branch (Reach 1) is proposed at a
1.5:1 credit ratio, based on valley length. This considers that vegetation is already well established.
Greene Branch Reach 2, an incised and maintained ditch, will be restored with Priority 1 restoration
approach. Jurisdictional wetlands will be avoided as much as possible; the only wetland impact will be
along the end of the reach, beginning approximately 190 linear feet above the confluence with Folly Ditch.
Within this area and within the roughly 220 linear feet above the start of the wetland impact, the proposed
bankfull profile will follow the existing ground nearly exactly with less than 0.2 feet of vertical deviation.
Along Greene Branch Reach 2 upstream of this area, the proposed bankfull profile generally follows the
existing top of bank elevations.
It should be noted that the permanent wetland impacts along lower Greene Branch will be limited to the
new channel location. Wetlands hydrology and vegetation will be rehabilitated over a broad area. Impacts
to the wetland identified in the preliminary JD (Wetland B, —1.56 acres) have been avoided as much as
possible. The proposed stream alignment does go through the wetland; however, the stream is at grade
and consequently the water table should be at least similar to the existing condition. A monitoring well has
been established to allow comparison of pre- and post -construction conditions.
Because of the backwater condition of Folly Ditch due to beaver activity, it is not necessary to have a steep
connecting grade on lower Greene Branch. Beaver maintenance has been attempted on lower Folly Ditch,
but, likely due to its proximity to the Great Dismal Swamp, it has proven difficult to prevent beaver from
returning. As described in Section 3.6, if necessary, Wildlands will contract to control beaver within the
conservation easement areas. Lower Folly Ditch is outside of the Site and will not be placed in a
conservation easement.
The restoration proposed for Greene Branch will meet the goals and objectives outlined in Table 13
(Section 5).
6.6.5 Barker Branch
Barker Branch will be restored using the Coastal Plain headwater valley approach. Unlike Greene Branch
Reach 1, most of this system exists within open agricultural fields. The conservation easement extends
approximately 250 feet to the south and 150 feet to the east-southeast upstream of the beginning of the
proposed work so that the resulting backwater from the starting elevation of the headwater valley will not
extend outside of the conservation easement. A headwater valley will be established where the existing
ditch converges with a shallow ditch from the east and leaves the treeline. Credit for this reach will not be
started until it reaches the intermittent/ephemeral break as determined by NCDWR. This location is
approximately 360 feet from where the headwater valley alignment commences.
The proposed alignment of the headwater valley follows the floodplain left of the existing ditch because
this area is lower in elevation than the right floodplain. An existing culvert crossing will be reconstructed in
essentially the same location and will be designed to blend into the proposed restoration work. Beginning
approximately 190 linear feet downstream of the crossing, the headwater valley will follow the existing
ditch for approximately 440 linear feet.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 25
To limit backwater to within the easement, as described above, valley cut will be required for roughly the
upper half of Barker Branch. For the lower half, the proposed headwater valley generally follows the
existing ditch top of bank elevations. As with Powell Branch Reach 1, appropriate steps will be taken to
preserve topsoil and facilitate plant growth within cut areas.
As Barker Branch approaches Folly Ditch, the proposed centerline is moved about 20 feet to the left of the
existing ditch to preserve existing trees. The alignment will slightly impact the edge of an existing
jurisdictional wetland (also Wetland B) that runs along the Folly Ditch. The higher restored profile, relative
to the existing ditch bottom, however, will enhance the hydrology of the adjacent wetlands. Additionally,
the wetland area will be placed in a conservation easement and planted with tree species appropriate for
its hydrology.
The restoration proposed for Barker Branch will meet the goals and objectives outlined in Table 13 (Section
5).
6.7 Vegetation, Planting Plan, and Land Management
6.7.1 Vegetation and Planting Plan
The Site will be planted and seeded with a combination of early and later successional native vegetation
chosen to create a coastal plain bottomland hardwood forest community. The specific species composition
will be selected based on the community type, observations from floristic inventory in the existing and
reference -reach buffers, and best professional judgment on species establishment and anticipated site
conditions in the early years following project implementation.
Potential species to be planted in the floodplain and wetland areas of the Site include bald cypress
(Taxodium distichum), swamp chestnut oak (Quercus michauxii), willow oak (Quercus phellos), sycamore
(Platanus occidentalis), river birch (eetula nigra), swamp tupelo (Nyssa biflora), and sweetbay (Magnolia
virginiana). Stream banks may be planted with species such as black willow (Salix nigra), Carolina willow
(Salix caroliniana), buttonbush (Cephalanthus occidentalis), and silky dogwood (Cornus amomum).
Understory species such as arrow wood (Viburnum dentatum) and winterberry (Ilex verticillata) will also be
included in the planting plan to enhance diversity.
Soil samples were collected and analyzed. Amendments will be added as necessary to achieve desirable pH
and nutrient levels. This includes composted poultry litter, lime, and humic acid. Soil composition test
results show possible subsoil deficiencies in zinc and magnesium. Plant growth and health will be
monitored to determine whether there is a need for diagnostic plant tissue sampling and additional soil
amendments.
Floodplain slopes will have grades that range from 5:1 to 10:1 to reduce rilling before vegetation
establishes and to better stabilize soil structure. Stockpiled topsoil will be reapplied with the necessary soil
amendments after the final slopes are completed. Wildlands will work to establish temporary vegetation
on these slopes as quickly as possible to ensure erosion is limited. Where grading is required to lower
floodplain elevations topsoil will be stockpiled and combined into subsurface soil with composted poultry
litter to achieve final grades.
Wildlands will also work to reduce soil compaction in highly compacted areas such as farm or haul roads.
This will be accomplished by ripping the soil with an excavator or an agricultural ripping element (e.g. chisel
plow). Ripping these areas will reduce plant growth -limiting bulk densities and increase porosity for better
water absorption by the soils. Soil compaction may also be reduced on larger areas with less severe
compaction by seeding annual species such as daikon radish or other tillage radish varieties specifically
bred to reduce soil compaction. The mix of vegetation on the site will also include N-fixers such as partridge
pea (Chamaecrista fasciculata var. fasciculata) that will improve soil fertility on the site.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 26
Adding or incorporating ramial wood chips to the floodplain is another approach that Wildlands may
employ. Ramial wood chips are made from small diameter stems and branches (<2.5") of hardwood tree
species and are beneficial to soil restoration by promoting mycorrhizal and saprophytic fungal growth. The
cambium to cellulose ratio of small -diameter branches is high so that the carbon to nitrogen ratio is low.
This avoids the soil nitrogen robbing capacity that is known to occur when 'green wood' decays on the
ground surface. Instead, it adds organic material and promotes fungal growth. This, or any other, addition
of organic material of will also make macro- and micro -nutrients more available to plants and act as a
buffer in acidic or basic soils.
In summary, Wildlands understands it will be held to the tree survival and growth performance standards
specified in the October 2016 Wilmington District Compensatory Mitigation Update.
Additional monitoring and maintenance issues regarding vegetation can be found in Appendix 6.
6.7.2 Land Management
The primary purpose of land management prior to construction is to effectively prepare and set the stage
for successful ecological restoration. This includes site preparation, soil testing and amendments, and
chemical and mechanical treatments to remove non-native invasive species. Dense infestations of Chinese
privet (Ligustrum sinense) in portions of the Site make this species a primary target. Japanese honeysuckle
(Lonicera japonica), autumn olive (Elaeagnus umbellate) and mimosa (Albizzia julibrissin) have been
identified as secondary targets for chemical treatment. Prior to construction, in two heavily privet -infested
portions of the easement Wildlands anticipates work -intensive cut stump treatment.
The Site will be monitored for non-native invasive species and treated as necessary during the monitoring
period. Additionally, Wildlands will also monitor the Site for future land management issues such as
floodplain erosion, areas of poor vegetation growth, and boundary encroachments.
6.8 Utilities, Stream Crossings, and Site Access
Table 19 summarizes the proposed crossings on the Site. The only crossing that is included in the easement
is that on Greene Branch because livestock are in this area. This crossing will be fenced with 5-strand
barbed wire or charged high -tensile wire and gated.
The crossings will be designed to allow for fish passage and aquatic habitat continuity. Culvert pipes will be
buried 6 to 12 inches to allow for a natural stream bed through the crossing. Many existing culverts on the
Site have vertical profile steps at the outfalls, posing a challenge to fish passage. Restoration activities will
help to improve aquatic passage and stream habitat by replacing these perched culverts and allowing for a
continuous stream bed habitat.

There are two additional culverts but these do not, per se, constitute Site crossings. The culvert at the
downstream end of Folly Swamp Reach 2 will be replaced. And the culvert being installed to add drainage
area to Greene Branch will be upstream of where stream crediting begins.

7.0 Determination of Credits
The final stream credits proposed for the Site are listed in Table 20. All the stream buffers measure will be
at least 50 feet from the top of the stream banks, with some exceptions in the vicinity of reach starts and
finishes. These exceptions total much less than 5% of the total project stream length. The credit release
schedule is in Appendix 7.

8.0 Performance Standards
The stream performance standards for the Site will follow approved performance standards presented in
North Carolina Interagency Review Team's (NCIRT) Monitoring Requirements and Performance Standards
for Compensatory Mitigation in North Carolina (February 2013) and the Wilmington District Stream and
Wetland Compensatory Mitigation Update (NCIRT, October 2016). Annual monitoring and routine site visits
will be conducted to assess the condition of the finished project by a qualified scientist. Specific
performance standards that apply to the Site are those described in the 2016 Compensatory Mitigation
Update including Vegetation (Section V, B, Items 1 through 3), Stream Channel Stability and Stream
Hydrology (Section VI, B, Items 1 through 7), and Headwater Stream Performance Standards (Section Vill, B,
Items 1 and 2). Table 21 summarizes performance standards.

Signs of encroachment, stream instability, invasive species.
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. It is important to note
that in sand bed channels, pools and bed forms (ripples, dunes, etc.) may migrate overtime as a natural
function of the channel hydraulics. It is also of note that sand bed streams are highly mobile and movement
of the bed material during storm events is not considered a sign of instability. This could lead to changes in
pool depth from storm to storm. These sorts of bed changes do not constitute a problem or indicate a need
for remedial actions. If channel changes indicate a movement toward stability, remedial action will not be
taken.
This is a sand bed system and the nature of the bed material is not expected to change over time. No
pebble counts will be conducted for the project reaches and no performance standard is being set for
substrate.
Wetlands have been degraded due to ditching, drain tiles, and stream channelization. Though no wetland
credits are being sought, the proposed restoration work should create wetlands along the restored
channels. Wildlands will install a monitoring well at each restoration area to document relatively high water
table levels. For the existing wetlands along Folly Swamp and Greene Branch, these gages will also help
assess the impacts to wetland hydrology from the mitigation project.
The extent of invasive species coverage will be monitored and controlled as necessary throughout the
required seven-year monitoring period. All herbicide applications will be performed in accordance with the
NC Department of Agriculture rules and regulations.
9.0 Monitoring Plan
An annual Site monitoring plan has been developed to ensure that the required performance standards are
met, and project goals and objectives are achieved. Annual monitoring reports will provide data and a
chronology that will facilitate an understanding of Site status and assist in decision making regarding close-
out. The monitoring period will extend seven years beyond completion of construction or until
performance criteria have been met.
Table 22, below, describes how the monitoring plan is set up to verify project goals and objectives have
been achieved.

1. Cross -sections will be permanently marked with rebar to establish location. Surveys will include points measured at all breaks
in slope, including top of bank, bankfull, edge of water, and thalweg.
2. Pattern and profile will be assessed visually during semi-annual site visits. Longitudinal profile will be collected during as -built
baseline monitoring survey only, unless observations indicate widespread lack of vertical stability (greater than 10% of reach is
affected) and profile survey is warranted in additional years to monitor adjustments or survey repair work.
3. Crest gages and/or flow gages will be monitored using automated pressure transducers. Transducers will set to record bank
full events at least twice a day, stream flow at least every 3 hours, and will be inspected quarterly.
4. Both mobile and permanent vegetation plots will be utilized to evaluate the vegetation performance for the open areas
planted. Two percent of the open planted acreage will be monitored with permanent and mobile plots. Permanent vegetation
monitoring plot assessments will follow CVS Level 2 protocols. Mobile vegetation monitoring plot assessments will document
number of planted stems and species using a circular or 100 m2 square/rectangular plot. Planted shaded areas will be visually
assessed.
5. Groundwater well data will be collected for informational purposes only. Results are not tied to success criteria nor stream
crediting.
6. Locations of exotic and nuisance vegetation will be mapped
7. Locations of vegetation damage, boundary encroachments, etc. will be mapped.
8. Coastal Plain Headwater Photo Points will be taken multiple times a year as needed to document flow and channel
development.
10.0 Long -Term Management Plan
10.1 Ownership and Long-term Manager
The Site will remain in private ownership, protected in its entirety, and managed under the terms detailed
in the conservation easement. Unique Places to Save (UP2Save) will serve as the Grantee and long-term
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 32
manager and will be the party responsible for long-term management. The conservation easement will be
transferred to UP2Save prior to the initial credit release.
UP2Save is a 501c3 non-profit organization that is committed to land conservation through sustainable
planning and management. UP2Save has the ability, both logistically and financially, to monitor and enforce
the provisions of the conservation easement and long-term management plan. The organization operates
in a sustainable manner to facilitate operations well into the future. UP2Save has been approved to serve
as the easement holder and long-term manager on several mitigation banks in North Carolina, including the
Falling Creek, Daniels, Creek, Hoosier Dam, and Box Creek projects. Additional qualifications and UP2Save's
annual report can be provided upon request.
10.2 Long -Term Management Activities
Prior to the initial credit release and following authorization of the Mitigation Banking Instrument, the Site
will be protected in perpetuity with a conservation easement. Following the issuance of the close-out letter
(i.e., final determination of success), long-term management activities will be conducted to ensure the Site
remains perpetually monitored. The long-term manager will be responsible for inspecting the Site annually,
conducting the long-term management activities described below, and rectifying identified deficiencies as
necessary. The restrictions and long-term management responsibilities will convey with the land, should
the property be transferred in the future. The long-term manager will be responsible for periodic
inspection of the Site to ensure that the restrictions documented in the recorded easement are upheld.

with the conservation easement.
10.3 Funding Mechanism
Anticipated long-term management activities and their associated annual cost are listed in Table 25 below.
Wildlands will fund a stewardship endowment that will be managed by UP2Save. UP2Save's endowment is
designated to provide on -going revenue to support long-term management activities. The stewardship
endowment is invested to provide recurring revenue to cover the cost of anticipated annual activities,
easement defense, and violation resolution.
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 33
The level of effort for each activity is listed in hours or as a lump sum (LS). The cost per unit or labor rate
and anticipated frequency were utilized to calculate the total and annual activity cost. For example, the
steward anticipates four hours of staff time at a rate of $50 per hour to support adjacent landowner
coordination, which may consist of coordinating with current and adjacent landowners to ensure access
and maintain relationships and scheduling site visits. A conservative (lower than anticipated) rate of return
(or capitalization rate) of 4.50% and the estimated annual costs of the identified management activities
were utilized to determine the endowment funding requirement.

10.4 Contingency Plan
Should UP2Save be unable to fulfill the long-term management responsibilities, a plan to transfer the
responsibilities and stewardship endowment will be presented to the USACE. Long-term management
responsibilities will not be transferred unless the long-term manager receives written authorization from
the USACE.
11.0 Adaptive Management Plan
Upon completion of Site construction, Wildlands will implement the post -construction monitoring
protocols and minor remedial actions (routine maintenance — see Maintenance Plan in Appendix 6) will be
performed as needed for the duration of the monitoring period. Wildlands, as the Sponsor, will notify the
USACE immediately if monitoring results or visual observations suggest a trend towards instability, major
Wildlands Pasquotank Umbrella Mitigation Bank Draft Mitigation Plan
Folly Swamp Mitigation Site June 2020
Page 34
remedial actions are needed, or that performance standards cannot be achieved. Should major remedial
measures be required, the Sponsor will submit a Corrective Action Plan and coordinate with the USACE
until authorization is secured to conduct the adaptive management activities. The Bank Sponsor is
responsible for funding and/or providing the services necessary to secure any necessary permits to support
the proposed major remedial adaptive management actions, to implement the corrective action plan, and
to deliver record drawings that depict the extent and nature of the work performed. If the USACE
determines that the Bank is not meeting performance standards or the Sponsor is not complying with the
terms of the instrument, the USACE may take appropriate actions, including but not limited to: suspending
credit sales, utilizing financial assurances, and/or terminating the instrument.
12.0 Financial Assurances
Financial assurances will be provided in the form of insurance for the activities specified in this plan. The
insurance will assure performance of construction and monitoring work to restore, enhance and/or preserve
the project aquatic resources. The principal amount of the insurance will be based on Table 26, below.
Construction insurance will convert to monitoring insurance upon as -built report approval.
Wildlands Holdings VI, LLC will serve as the Named Insured and Nautilus Insurance Company will serve as
the insurance carrier. In the event that Wildlands Holdings VI, LLC fails to meet the conditions of the
Mitigation Plan, Nautilus may fulfill these obligations either by performing those obligations up to the
applicable annual Limits of Insurance described in the policy's Declaration Pages, or by paying such claim(s)
to a willing party acceptable to the USACE, who would develop a proposal to fulfill the mitigation
obligations. The insurance will stipulate that any insurance payouts be made payable to an established
third party. Unique Places to Save (UP2Save) is to serve as the third party for this Mitigation Bank. At such
time as funds are distributed to UP2Save, they will become a surety to the insurance. Financial assurances
will not be structured to provide funds to the USACE in the event of default by the Principal (Sponsor). The
USACE will be notified a minimum of 120 days prior to termination of financial assurances. A letter from
UP2Save acknowledging their third -party status is located in Appendix 8.
Insurance will be phased to allow coverage through the monitoring period. Insurance covering construction
will be provided after the MBI is approved and prior to the initial credit release. The casualty insurance will
be retired upon submittal of the final as -built report to the DE. The initial term of the insurance policy will
be 15 months and will include an option to renew the policy for a term not to exceed one year to cover site
construction. The principal amount of the construction insurance will be calculated based on the remaining
cost to complete engineering, permitting, and construction activities as described in Table 26. Note, the
cost of recording easements will not be included in the construction insurance as this process will be
complete at the time the insurance is submitted to the USACE.
Following retirement of the construction insurance, insurance for annual monitoring will be utilized to
cover anticipated monitoring and adaptive management costs. Insurance will be structured to provide
continuous coverage through a single policy that will decrement in value each year according to Table 26.
Annual monitoring insurance will be submitted to the USACE upon approval of each previous year's
monitoring report. The principal amount of monitoring insurance is calculated based on the total estimated
costs that remains through closeout, including monitoring and maintenance activities. Table 26 lists the
proposed insurance principal amounts for each monitoring year.

Site Protection Instrument
1.0 Site Protection Instrument
The land required for construction, management, and stewardship of this mitigation project includes
portions of the parcels listed in Table 1. This area totals 50.65 acres. The deed book and page number
listed are for the agreements on an option to purchase a conservation easement. A conservation
easement will be recorded on the parcels and includes streams and wetlands being restored along with
their corresponding riparian buffers.
Note that 1.59 acres of the conservation easement on the Barker parcel at the head of Greene Branch
(i.e., where culvert will be installed below to add natural drainage area) will be limited to a drainage
alteration restriction only. That is, trees will not be planted, and easement restrictions will be limited to
preventing the existing drainage pattern from being altered.

❑ I intend to construct/develop a projector perform activities on this parcel which would be
designed to avoid all jurisdictional aquatic resources under Corps authority.
❑✓ I intend to construct/develop a projector perform activities on this parcel which may
require authorization from the Corps, and the JD would be used to avoid and minimize
impacts to jurisdictional aquatic resources and as an initial step in a future permitting
process.
❑ I intend to construct/develop a projector perform activities on this parcel which may

Jurisdictional Determination Request
F. JURISDICTIONAL DETERNIINATION (JD) TYPE (Select One)
0 I am requesting that the Corps provide a preliminM JD for the property identified herein.
A Preliminary Jurisdictional Determination (PJD) provides an indication that there may
be "waters of the United States" or "navigable waters of the United States"on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional "waters of
the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is
"preliminary" in the sense that an approved JD can be requested at any time. PJDs do
not expire.
❑ I am requesting that the Corps provide an approved JD for the property identified herein.
An Approved Jurisdictional Determination (AJD) is a determination that
jurisdictional "waters of the United States" or "navigable waters of the United
States" are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner, permit applicant, or other "affected
party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).
❑ I am unclear as to which JD I would like to request and require additional information
to inform my decision.
G. ALL REQUESTS

■ Jurisdictional non -wetland features (i.e. tidal/navigable waters, tributaries,
impoundments) should be labeled as Non -Wetland Waters of the US, stream, tributary,
open water, relatively permanent water, pond, etc. Please include the acreage or linear
length of each of these features as appropriate.
■ Isolated waters, waters that lack a significant nexus to navigable waters, or non -
jurisdictional upland features should be identified as Non -Jurisdictional. Please
include a justification in the label regarding why the feature is non jurisdictional (i.e.
"Isolated", "No Significant Nexus", or "Upland Feature"). Please include the acreage
or linear length of these features as appropriate.
For Preliminary Jurisdictional Determinations:
Wetland and non -wetland features should not be identified as Jurisdictional, 404,
Waters of the United States, or anything that implies jurisdiction. These features can be
identified as Potential Waters of the United States, Potential Non -wetland Waters of
the United States, wetland, stream, open water, etc. Please include the acreage and
linear length of these features as appropriate.

2) In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring "pre -
construction notification" (PCN), or requests verification for a non -reporting NWP or
other general permit, and the permit applicant has not requested an AJD for the
activity, the permit applicant is hereby made aware that: (1) the permit applicant has
elected to seek a permit authorization based on a PJD, which does not make an
official determination of jurisdictional aquatic resources; (2) the applicant has the
option to request an AJD before accepting the terms and conditions of the permit
authorization, and that basing a permit authorization on an AJD could possibly result
in less compensatory mitigation being required or different special conditions; (3) the
applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can
accept a permit authorization and thereby agree to comply with all the terms and
conditions of that permit, including whatever mitigation requirements the Corps has
determined to be necessary; (5) undertaking any activity in reliance upon the subject
permit authorization without requesting an AJD constitutes the applicant's acceptance
of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps permit
authorization based on a PJD constitutes agreement that all aquatic resources in the
review area affected in any way by that activity will be treated as jurisdictional, and
waives any challenge to such jurisdiction in any administrative or judicial compliance
or enforcement action, or in any administrative appeal or in any Federal court; and (7)
whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms
and conditions contained therein), or individual permit denial can be administratively
appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic
jurisdiction exists over aquatic resources in the review area, or to provide an official
delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds
that there "may be"waters of the U.S. and/or that there "may be" navigable waters of
the U.S. on the subject review area, and identifies all aquatic features in the review
area that could be affected by the proposed activity, based on the following
information:

The Division of Water Resources (DWR) has determined that the streams listed above and included
on the attached map have been located on the most recent published NRCS Soil Survey of GATES
County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale
and evaluated for applicability to the Water Quality Standards. Each stream that is checked "Not
Subject" has been determined to not be at least intermittent or not present on the property. Streams
that are checked "Subject" have been located on the property and possess characteristics that qualify
them to be at least intermittent streams. There may be other streams or features located on the
property that do not appear on the maps referenced above but may be Considered jurisdictional
according to the US Army Corps of Engineers and subject to the Clean Water Act.

The Division of Water Resources (DWR) has determined that the streams listed above and included
on the attached map have been located on the most recent published NRCS Soil Survey of GATES
County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale
and evaluated for applicability to the Water Quality Standards. Each stream that is checked "Not
Subject" has been determined to not be at least intermittent or not present on the property. Streams
that are checked "Subject" have been located on the property and possess characteristics that qualify
them to be at least intermittent streams. There may be other streams or features located on the
property that do not appear on the maps referenced above but may be Considered jurisdictional
according to the US Army Corps of Engineers and subject to the Clean Water Act.

Travis Wilson/NCWRC
John Hutton/Wildlands
Chris Roessler/Wildlands
John Hutton and Chris Roessler of Wildlands Engineering, Inc. (Wildlands) led the group on a tour of the
Folly Swamp mitigation site in Corapeake, NC. The purpose of the tour was to present the site to a group
of IRT members and to get input on the management/mitigation options proposed for the site. During
the tour, the group discussed the condition of the channels on the site and the design options and
crediting scenarios they felt would be most appropriate to restore and enhance the channels. The
accompanying map identifies the stream reach names.
The tour began with the Folly ditch, then visited Jordan Branch, Powell Branch, Greene & Pollo Branch,
and concluded with Morgan Branch. Comments provided during the site visit are listed below by reach.
Folly Ditch/Swamp
The project is called Folly Swamp because that is the name given to the main channel on most available
maps. However, the locals refer to the channel as the Folly ditch. Wildlands learned this week that the
Drainage District was established in the 1930s and the channel has been maintained as a ditch since
then.
Wildlands proposes to create a wide, excavated floodplain with a meandering, single -thread channel.
John Hutton explained that the floodplain width on Folly Swamp will be approximately 100 feet with a
gently sloped transition to existing grade. Anthony Scarborough pointed out that E&S permits require
excavated dirt to be wasted on the project parcel from which it originated.
The Drainage District understands that they will not be able to clear and maintain the channel as they
have in the past and will need to sign agreements stating such. We will coordinate with the IRT on the
form of this agreement. Wildlands will obtain a no -rise certification from FEMA and NC Flood Mapping
to ensure that flooding will not be made worse by the project.
IRT members questioned the functional uplift potential of Priority 2 restoration in this setting. They cited
past problems with soil impacts from this approach that have resulted in poor tree growth. Nearby Duke
Swamp is a good example, where approximately 10-year-old trees are 10 feet tall. Wildlands heard more
about the specifics of this from the regulators and recognizes the challenges. We are open to further
suggestions but plan to save the topsoil to incorporate it at the excavated depth. Also, based on soil test
recommendations, Wildlands will add lime to raise the pH, use low pH seed mix as needed, and
incorporate fertilizer.
Adding ramial wood chips to the floodplain is another approach that Wildlands may employ. Ramial
wood chips are made from small diameter stems and branches (<2.5") of hardwood tree species and are
beneficial to soil restoration by promoting mycorrhizal and saprophytic fungal growth. The cambium to
cellulose ratio of small -diameter branches is high so that the carbon to nitrogen ratio is low. This avoids
the soil nitrogen robbing capacity that is known to occur when 'green wood' decays on the ground
surface. Instead, it adds organic material and promotes fungal growth. This material could be obtained
by thinning the hardwood saplings surrounding the immature pine stands along Jordan Branch.
In sum, Wildlands understands it will be held to the tree survival and growth performance standards
specified in the October 2016 Wilmington District Compensatory Mitigation Update.
For biological functional uplift, Wildlands will conduct pre- and post -construction surveys of benthic
macroinvertebrates and amphibians. We are not sure that benthic communities will improve within the
7-year monitoring period but are willing to investigate. It may take additional time to observe the
pollution intolerant and diverse communities seen in mature forest settings. Amphibian communities,
however, are expected to significantly improve within the conservation easement area, which now
includes row crop fields and cattle pasture.
Past projects have shown that wetlands will likely form on the excavated floodplains. To show that the
excavated floodplains will show a higher water table and improved hydrology, Wildlands will include a
monitoring well at each restoration area. We are not seeking wetland mitigation credit, however.
Kyle Barnes commented that the access corridor (elevated road) along upper Folly Ditch may interfere
with the project and conservation easement. Wildlands explained that a crossing will be established
near the existing crossing and that the access easement will be entirely outside of the conservation
easement. We have left space for this access on the north side of the proposed conservation easement
(see Folly Swamp — Reach 1 in attached map).
Mac Haupt commented on the disconnectedness of the project, with four separate mitigation areas and
some short lengths. A review of the concept map shows that what hasn't been included are primarily
wooded areas. Wildlands recognized this as a concern during option acquisition but thought the IRT
would not approve channel restoration or enhancement for mitigation in those areas and therefore did
not pursue conservation easements. Restoration or enhancement would impact wetlands and require
significant tree removal. These reaches are not of preservation quality either due to manipulation and
maintenance by the Drainage District. Wildlands also tried to address Mac's general concern about
disconnected projects areas by maintaining a minimum 3,000 ft length per area. Except Powell Branch,
this minimum was achieved.
Jordan Branch
As a direct tributary to the project reach of the Folly ditch, Wildlands wanted to include Jordan Branch in
the mitigation project. However, upon further review, including seeing it with low flow in December, it
will be mostly dropped from the project. Wildlands proposes to restore approximately 250 linear feet of
the existing Jordan ditch. This will enable it to tie into an elevated Folly Swamp without causing a
lengthy backwater effect.
Powell Branch
Chris Roessler explained that Powell Branch has a mapped drainage area of 115 acres but that it is
actually larger because the ditch at the upstream end has been historically reversed to drain to the
project channel. He also stated that the area has been relatively dry in recent months, having largely
been missed by Hurricanes Florence and Michael. Each of September, October, and November had
between 3.0 and 3.5 inches of rain. Dave Lekson looked at PRISM data on his phone and confirmed the
project area has received below normal rainfall.
Kyle Barnes stated that the upper end is not a jurisdictional channel because it lacks an ordinary
highwater mark and had upland vegetation in the ditch. Also, the channel goes through high ground in
the middle of the reach, in the vicinity of the excavated pond.
Chris Roessler talked to the landowner after the IRT field meeting to confirm the background of this
area. The pond was excavated between 1959 and 1961 to a depth of 16 feet. Dirt from the pond was
piled around it and used over the years to fill low spots on the farm. Not all the dirt has been removed,
however, leaving the possibility that the high ground that Powell Branch runs through was from the
pond spoil.
The figure below is from the 1929 Gates County Soil Survey, which is before the Drainage District was
established in the 1930s. The map appears to show Powell Branch as an intermittent stream within the
project area.
This map is available at https://web.lib.unc.edu/nc-maps/interactive/MC 041 1929d c2.php

And here is the current USGS topo of Powell Branch, including the excavated pond:
If USACE would like to take a closer look at Powell Branch to make a final call on its jurisdictional status,
Wildlands would be in favor of that. However, if the answer is essentially already known, then Powell
Branch can be removed from the project.
Greene Branch
Wildlands proposes to use a headwater restoration approach on upper Greene Branch if there is
sufficient evidence that the channel will have 30 days of consecutive flow after connecting the low point
of the valley with its upper watershed. Currently, the valley is disconnected with its upper watershed by
a road and ditches on the adjacent farm. Wildlands proposes to install weirs and pressure transducers
on the adjacent farm ditches, as well as on middle Greene Branch and Pollo Branch, to determine if it
will have sufficient hydrology to support the proposed mitigation approaches.
IRT members agreed with this approach and stated that the project reaches would need to meet the 30-
day flow requirement to receive mitigation credit. A camera or other monitoring device was
recommended instead of a pressure transducer for post restoration monitoring. Otherwise, the IRT
members agreed with the proposed approaches on Pollo Branch and Greene Branch Reaches 1 and 2.
Lower Greene Branch (Reach 1) was proposed for Priority 2 restoration in the Prospectus. Priority 1
restoration is possible and will be targeted at the upper end. Kyle Barnes noted apparent JD wetlands in
the lower field and that Priority 2 restoration would impact those. Wildlands will investigate ways to
avoid and minimize impacts to any jurisdictional wetlands that may include extending the Priority 1
approach, using an alignment that avoids wetlands, or some other measure.
Morgan Branch
The last site visit of the project was Morgan Branch. Morgan Branch was proposed for Priority 2
restoration in the Prospectus. Wildlands will achieve Priority 1 restoration or very shallow Priority 2
restoration by the large pine tree on the existing ditch.
IRT members stated that other Priority 2 related concerns about the Folly ditch section above apply to
Morgan Branch. Wildlands proposes to address these concerns in the same way (i.e., soil amendments,
biological monitoring, tree performance standards, etc.).
Summary and Conclusion
The IRT questioned the functional uplift potential of the site given the general Priority 2 approach to
many channels proposed by Wildlands. We hope we have addressed some of that concern with these
meeting minutes. An updated credit table is provided below. As discussed above, we can remove Powell
Branch from the project if the IRT chooses.

Kyle Barnes will serve as the Project Manager for USACE and the main point of contact. Chris Roessler
will be the Wildlands Project Manager and coordinate/submit project deliverables directly to Kyle
Barnes for distribution to all NCIRT team members.
Action Items and Next Steps
• The IRT will consider these meeting minutes and provide feedback to Wildlands.
• Project Schedule — Wildlands is ready to proceed with project survey in the coming months.
• USACE requires Jurisdictional (JD) stream/wetland calls for the project. Wildlands will coordinate
with Kyle Barnes (or assigned) for on -site JD verification prior to mitigation plan submittal.
• After the jurisdictional determination has been conducted, any wetland areas that will be
impacted by the proposed work (filled or drained) will need to be identified and functional
replacement for those losses will be proposed and discussed in the draft mitigation plan.
• Signage will be needed on all conservation easement areas.
This represents Wildlands' interpretation of the meeting discussions. If any meeting attendees should
find any information contained in these meeting minutes to be in error and/or incomplete based on
individual comments or conversations, please notify Chris Roessler with corrections/additions as soon as
possible.

Comments on the Folly Swamp Minutes
January 24, 2019
1. Folly Ditch/Swamp- while DWR applauds WEI for engaging a project within a Drainage District,
until the roles and restrictions (and written affirmation) can be better realized by the Drainage
District regarding this proposal, DWR will reserve final judgement on the proposal on Folly Ditch
and all other proposed reaches in the prospectus.
WEI heard the concerns regarding the priority 2 approach on these type of streams from the
I RT.
The Folly Ditch is currently the only stream reach over 3,000 linear feet.
2. Jordan Branch- WEI reduced the length given the flow conditions, DWR concurred.
3. Powell Branch- This reach seemed to have some flow issues and Kyle Barnes stated the lack of
jurisdictional status in the upper reach. This reach has a red flag concerning flow and is a short
reach.
4. Greene Branch- The minutes state WEI intends to use a headwater approach in the upper
reach, however, in the proposed credits reach 1 shows a significant increase in project length.
The headwater approach utilizes valley length, DWR believes the amount of credit proposed
here would be reduced. In addition, this headwater reach will likely be dependent on the
hydrology that will come from an adjoining field outside the easement area. Until there is a
determination that 1) enough flow would be contributed to the headwater reach, and 2) there is
an agreement from the adjoining landowner that allows the flow to enter the reach, the viability
of the reach remains in question. A positive for the Greene and Pollo Branch is that there is a lot
of opportunity for nutrient abatement given the adjoining animal operations. Moreover, at the
bottom of Greene Branch, wetlands were noted and hopefully the design will incorporate
measures to maintain/enhance these resources.
5. Morgan Branch- DWR concurs with the minutes
6. Table of Proposed Stream Mitigation Credits- without getting too much into the design aspects
here, the proposed lengths seem high on several reaches, yielding a roughly calculated higher
than expected sinuosity. For example, proposed length of Folly ditch works out to roughly 1.33
sinuosity. There are similar concerns on the other reaches.
7. Overall, DWR maintains its position that the project is disconnected and most reaches are under
3,000 linear feet. Given the other comments provided by the IRT members regarding priority 2
project concerns in the coastal plain, DWR believes that for this project to move forward, some
of the issues regarding the Greene Branch would need to be resolved.
Kyle, below are my comments on the Folly Swamp field visit and meeting summary:
1. The discussion on Drainage Districts is of concern, and until we have a signed agreement from them stating that
channel maintenance will not occur on Folly Ditch, or any of the project channels, I am hesitant to continue to the
Final Prospectus stage of this Bank.
2. For the project as a whole, I understand the constraint of doing Priority 1 restoration due to the risk of flooding
adjacent properties; however, with the majority of the project being proposed as P2, there is very little functional
uplift, aside from a riparian buffer, that will occur. In order to justify 1:1 credits for restoration, you should be
restoring the system to its original state, which is not what is currently proposed. It's understood that there will be
considerable earthmoving associated with the proposed P2, but the burden of proof will be on Wildlands to justify
the functional uplift associated with a 1:1 ratio.
3. Powell Branch, along with all project streams and associated wetlands, will need a JD. If it's determined that a
portion of Powell Branch is not jurisdictional, that entire reach should be dropped from the Final Prospectus.
4. Greene Branch and Pollo Branch: a headwater valley approach through the woods seems appropriate, if in fact
you are able to divert water from the adjacent property to the east via the culvert at the fenceline, otherwise flow
remains a concern here. Lower Greene Branch is of concern, especially at the lower end, and appears to be more
wetland -like, especially if the channel is raised here for P 1. It's likely that the wetlands in this area will have
increased hydrology from raising the stream channel, but flow continues to be a concern.
5. Morgan Branch would benefit from P1 for as much linear footage possible.
Thanks for the opportunity to comment,
Kim

IRT Field Meeting Notes — Folly Swamp May 13, 2019
Meeting Attendees
Kyle Barnes/USACE
John Hutton/Wildlands
Chris Roessler/Wildlands
Kyle Barnes met with John Hutton and Chris Roessler on April 24, 2019 to review two of the areas that
are part of the Folly Swamp mitigation site in Corapeake, NC. The purposes of the meeting were to look
at the jurisdictional status of Powell Branch, discuss some of the issues brought up in IRT meeting about
Greene Branch, and to review another channel that is adjacent to Greene Branch.
Comments provided during the site visit are listed below by reach.
Powell Branch
Wildlands installed a weir and flow gage on this site in March and data collection began on March 15tn
The weir was undermined by storm flow on March 25t" but in the intervening time consistent
streamflow was measured. John Hutton provided Kyle Barnes with a plot of the streamflow.
Kyle acknowledged that the stream looked a good bit different than on the IRT site visit in December. He
observed a consistent ordinary high water mark. He then looked upstream at the two channels that
drain to the project reach. The one to the west is an agricultural ditch that has been historically
redirected to flow to Folly Swamp. The one to the east, coming out of the woods, appeared to be a
jurisdictional stream on the downstream end. Kyle OK'd this area of the project from a jurisdictional
standpoint.
One concern Kyle brought up was the amount of flow input coming from the agricultural ditch to the
west versus the natural stream feature and the fact that the farmer could ditch it to drain away from the
project. Chris and John spoke with Mr. Powell, who owns Powell Branch within the project limits as well
as all of the fields that drain to the agricultural ditch. Mr Powell is also the Chairman of the Drainage
District that includes Folly Swamp. He stated that there is no way to make the grade work to drain the
fields away from the project area.
Wildlands will update the Prospectus to include this information.
Greene Branch
The group next looked at the gage placed on the ditch that is on the Barker property, just above the
head of Greene Branch. The proposal in this area is for Wildlands to install a culvert to add drainage area
to Greene Branch and use an outer Coastal Plain headwater approach on upper Greene Branch.
The gage on the Barker ditch measured consistent flow from March 15 to April 10, at which point the
weir became undermined. It is encouraging that flow was measured on all 26 days of recording. The bar
for hydrology on upper Greene Branch is 30 consecutive days of flow each year.
Kyle expressed concerns about installing a culvert and having the drainage to it last forever. While Chris
talked with the farmer, John and Kyle discussed placing a conservation easement or deed restriction on
a 1- to 2-acre area upstream from the culvert that essentially prevents the landowner from altering the
drainage pattern. Wildlands will seek to obtain a conservation easement or deed restriction that
prevents alteration to the drainage in the area surrounding the culvert.
The group walked downstream and viewed the gage at Pollo Branch. This showed consistent flow.
Next the group looked at the gage on Greene Branch. This showed consistent flow and Kyle commented
that it had more water than he expected for this time of year.
Barker Branch
Next the group looked at the channel (Barker Branch) to the east of Greene Branch on the Barker
property. Wildlands is in discussions with the landowner about adding it to the mitigation project. Kyle
observed a consistent ordinary high water mark from the tree line downstream to the Folly ditch and
stated that it was appropriate for Priority 1 restoration. He cautioned that it is important to look at
drainage leading into the easement because any problems created by the project are likely to lead to
alterations by the farmer. John and Kyle discussed that the wetlands would be mapped and presented in
a PJD application and the design would seek to avoid impacts. Wildlands plans to use a NW 27
application to obtain a 404 permit. Kyle agreed with this approach.
The group then looked at the upper portion of Barker Branch beginning at the wood line where a
drainage ditch enters from the east. Kyle noted the ordinary high water mark along this section was not
consistent and he did not believe it was jurisdictional from a Corps' perspective. John suggested that
Wildlands install a gage to monitor hydrology and also request that Anthony Scarbraugh do a stream
determination from a DWR perspective. Kyle agreed with this. Based on the results of additional
monitoring, if single thread Priority 1 restoration was not acceptable, Chris suggested an outer coastal
plain headwater approach. Kyle cautioned against over engineering but thought it may be workable and
confirmed that an ordinary high water mark is not required for the headwater approach. Wildlands will
further investigate options for upper Barker Branch.
Action Items and Next Steps
Wildlands will update the Prospectus based on feedback from the December IRT meeting and Kyle
Barnes in this past meeting. Kyle will look to public notice the Prospectus soon after.
Wildlands plans to begin survey soon and will present a PJD application in the coming months prior to
commencing substantial design efforts.
Wildlands will look to provide conceptual agreements with the Drainage District and Mike Barker (re.
culvert installation and drainage conservation easement/deed restriction) that the IRT requested in the
December meeting minutes.
This represents Wildlands' interpretation of the meeting discussions. The minutes will be presented to
Kyle Barnes for confirmation. Kyle accepted the minutes with one change, which is captured in this
version.
Sincerely,
Chris Roessler

Folly Swamp Mitigation Site, Gates County, NC
Pasquotank River Basin - 03020105
USACE Action ID No. SAW-2018-02026
Dear Mr. Barnes,
Wildlands received comments from the NC IRT dated January 24, 2019 on the Folly Swamp field meeting
minutes. The field took place on December 18, 2018. This letter provides our responses to those
comments.
Comments on Folly Swamp Field Meeting Minutes
Mac Haupt, NCDWR, January 7, 2019
1. Folly Ditch/Swamp —while DWR applauds WEI for engaging a project within a Drainage District,
until the roles and restrictions (and written affirmation) can be better realized by the Drainage
District regarding this proposal, DWR will reserve final judgement on the proposal on Folly Ditch
and on other proposed reaches in the prospectus.
WEI heard the concerns regarding the Priority 2 approach on these type of streams from the IRT.
The Folly Ditch is currently the only stream over 3,000 linear feet.
Wildlands provides a conceptual understanding with the Folly Swamp Drainage District in the
updated Prospectus. A more formal and detailed agreement will be established once the design
nears completion.
The existing length of Morgan Branch is approximately 3,000 feet and the proposed length of
Greene Branch area, with Barker Branch which will be connected through a conservation
easement, is more than 3,000 feet. Only Powell Branch is clearly less than 3,000 feet.
2. Jordan Branch —WEI reduced the length given flow conditions, DWR concurred.
3. Powell Branch —This reach seemed to have some flow issues and Kyle Barnes stated the lack of
jurisdictional status in the upper reach. This reach has a red flag concerning flow and is a short
reach.
Wildlands Engineering, Inc. (P) 919.851.9986 • 312 West Millbrook Road, Suite 225 • Raleigh, NC 27609
From the updated Prospectus, Section 3.1.1.:
Some question of Powell Branch's jurisdictional status were raised by IRT members during a
December 18, 2018 site visit. However, after seeing the site again on April 24, 2019, Kyle Barnes
considered it to be jurisdictional with a consistent ordinary high water mark. Additionally, of the
two channels upstream of Savage Road leading to the project reach at least the original one
coming from the southern wooded area appears to be jurisdictional. Wildlands installed a weir
and flow gage on Powell Branch in March and data collection began on March 151h.The weir was
undermined by storm flow on March 251h but in the intervening time consistent streamflow was
measured. Minutes from both site visits are included in Appendix F.
4. Greene Branch — The minutes state WEI intends to use a headwater approach in the upper reach,
however, in the proposed credits reach 1 shows a significant increase in project length. The
headwater approach utilizes valley length, DWR believes the amount of credit proposed here
would be reduced. In addition, this headwater reach will likely be dependent on the hydrology
that will come from an adjoining field outside the easement area. Until there is a determination
that 1) enough flow would be contributed to the headwater reach, and 2) there is an agreement
from the adjoining landowner that allows flow to enter the reach, the viability of the reach
remains in question. A positive for the Greene and Pollo Branch is that there is a lot of
opportunity for nutrient abatement given the adjoining animal operations. Moreover, at the
bottom of Greene Branch, wetlands were noted and hopefully the design will incorporate
measures to maintain/enhance these resources.
Apologies because the reaches were labeled backwards in the meeting minutes. Reach 3 in the
minutes table is the one that will follow the headwater approach and it uses valley length. (It
has been relabeled as Reach 1 in the updated Prospectus). Wildlands established a flow
monitoring device in the ditch on the neighboring Barker property and learned that a small
amount of stream flow was present from mid March to mid April. Wildlands will establish a
conceptual agreement with the Barkers to install a culvert to connect the agricultural ditches to
upper Greene Branch. The Barkers have verbally agreed to this.
Jurisdictional wetlands will be mapped at all sites and considered in the design process.
Measures will be taken to maintain or enhance these resources.
5. Morgan Branch — DWR concurs with the minutes.
Sounds good.
6. Table of Proposed Stream Mitigation Credits —without getting too much into design aspects
here, the proposed lengths seem high on several reaches, yielding a roughly calculated higher
than expected sinuosity. For example, proposed length on Folly ditch works out to roughly 1.33
sinuosity. There are similar concerns on other reaches.
The anticipated sinuosity on all the single -thread restoration reaches was reduced to
approximately 1.22. Wildlands will investigate sinuosity on reference reaches, valley width, and
sediment transport before making a final determination on proposed sinuosity.
7. Overall, DWR maintains its position that the project is disconnected and most reaches are under
3,000 linearfeet. Given the other comments provided by the /RT members regarding Priority 2
project concerns in the coastal plain, DWR believes that for this project to move forward, some
of the issues regarding the Greene Branch would need to be resolved.
This is a large project with more than 14,000 stream credits likely involved. Please see response
to first DWR comment.
Wildlands is committed to working with the IRT to make sure existing jurisdictional wetlands are
maintained or enhanced, as well as to create new wetland features.
Wildlands has worked to demonstrate that 30 days of flow are likely on Greene Branch. A
culvert will be added to connect additional drainage area above Greene Branch. Additionally,
Wildlands will work with the landowner to obtain a conservation easement that prevents
drainage alteration. We have also added Barker Branch, which will connect to lower Greene
Branch via a conservation easement.
Kim Browning, USACE, January 24, 2019
1. The discussion on Drainage Districts is of concern, and until we have a signed agreement from them
stating that channel maintenance will not occur on Folly Ditch, or any of the project channels, I am
hesitant to continue to the Final Prospectus stage of this Bank.
This is the same response to DWR's first comment. Repeated:
Wildlands provides a conceptual understanding with the Folly Swamp Drainage District in the
updated Prospectus. A more formal and detailed agreement will be established once the design
nears completion.
2. For the project as a whole, I understand the constraint of doing Priority 1 restoration due to the risk
of flooding adjacent properties; however, with the majority of the project being proposed as P2,
there is very little functional uplift, aside from a riparian buffer, that will occur. In order to justify 1:1
credits for restoration, you should be restoring the system to its original state, which is not what is
currently proposed. It's understood that there will be considerable earthmoving associated with the
proposed P2, but the burden of proof will be on Wildlands to justify the functional uplift associated
with a 1:1 ratio.
Priority 2 is done for 1:1 credit in other parts of the state. Wildlands would like to know that if
we address Priority 2 as outlined in the updated Prospectus, whether that would alleviate the
IRT's concerns about functional uplift. Is there anything that could be added? Perhaps Wildlands
could show the area with a higher water table before and after restoration.
3. Powell Branch, along with all project streams and associated wetlands, will need a JD. If it's
determined that a portion of Powell Branch is not jurisdictional, that entire reach should be dropped
from the Final Prospectus.
Wildlands met with Kyle Barnes on April 24, 2019. At this site visit, Kyle affirmed that Powell
Branch is a jurisdictional channel. Minutes from this meeting are included in the updated
Prospectus.
4. Greene Branch and Pollo Branch: a headwater valley approach through the woods seems
appropriate, if in fact you are able to divert water from the adjacent property to the east via the
culvert at the fenceline, otherwise flow remains a concern here. Lower Greene Branch is of concern,
especially at the lower end, and appears to be more wetland -like, especially if the channel is raised
here for P 1. It's likely that the wetlands in this area will have increased hydrology from raising the
stream channel, but flow continues to be a concern.
Wildlands proposes a headwater approach for upper Greene Branch and upper Barker Branch.
Flow monitoring, described in the updated Prospectus, indicates 30 consecutive days of flow will
be attainable on Greene Branch.
Jurisdictional wetlands will be mapped at all sites and considered in the design process.
Measures will be taken to maintain or enhance these resources.
5. Morgan Branch would benefit from P1 for as much linear footage possible.
We agree and will strive for that.
We hope that these responses adequately address the IRT's comments and we look forward to working
with the IRT during the next phases of this project.

This correspondence is in reference to the proposed compensatory mitigation bank known
as Pasquotank Umbrella Mitigation Bank (Bank). The Bank consists of five sites totaling 47
acres all flowing to Folly Swamp. The sites are located approximately four miles north of the
town of Sunbury on NC 32 in Gates County, North Carolina. The sites are located on named and
unnamed tributaries within the Pasquotank River Basin (HUC 03010205).This correspondence
refers to comments received in response to Interagency Review Team (IRT) reviews and a Public
Notice dated August 22, 2019.
After review of the public notice, project prospectus, and/or our on -site meetings, the North
Carolina Division of Water Resources (NCDWR), the North Carolina Department of Natural
Resources State Historic Preservation Office (SHPO), the United States Department of the
Interior Fish and Wildlife Service (USFW) and the US Army Corps of Engineers (Corps)
provided comments which are enclosed for your review. It is Department of the Army policy to
provide a project proponent the opportunity to furnish a proposed resolution or rebuttal to all
comments and/or objections from the public and government agencies before a final decision is
made. In this regard, I would appreciate receiving any comments that you have on the comments
received.
Also, pursuant to 33 CFR Part 332.8 (d)(5), Initial Evaluation, I have determined that your
proposed mitigation bank has potential for providing appropriate compensatory mitigation for
activities authorized by Department of the Army permits. We share some of the same concerns
outlined by the IRT which should be resolved as the bank is finalized through the interagency
review process.
Accordingly, you may proceed with preparation of the draft mitigation banking instrument
(MBI) as directed by 33 CFR Part 332.8 (d)(6), Draft Instrument and finalization of your
mitigation plan. Thank you for your time and cooperation. If you have any questions, please

the wetlands in this area will have increased hydrology from raising the stream channel, but flow
continues to be a concern.
5. Morgan Branch would benefit from P1 for as much linear footage possible.
Kyle's Comments:
1) The Pasquotank HUC is 03010205. The prospectus indicates the Pasquotank HUC as 03020105 in
multiple locations.
2) Wetlands have been identified outside of the project area along Folly Swamp Reach 1. 1 have
concern that there may be a drainage effect on these adjacent wetlands.
3) The project as discussed will result in a significant amount of spoil and the needed area to
stockpile. Areas adjacent to Powell Branch and within the floodplain of the non -project area of
Folly Swamp have been identified as spoil stockpile areas. Removing vegetation and stockpiling
spoil within these areas are counter to the purpose of stream and wetland mitigation. These
areas should be avoided for spoil stockpiling because it removes or reduces existing
buffer/riparian area.
4) Same concern for Morgan Branch. Stockpiling spoil in the identified area only limits the function
of the buffer/riparian area outside of the project area.
5) Barker Branch: I have concern that the project will have issues with the owner/farmer when the
land outside of the easement becomes wetter. There needs to be a larger easement area to
prevent additional ditching and draining when the agricultural fields become too wet to farm.
6) Green Branch: The headwater approach in upper Green Branch is a concern due to the fact that
it is fully dependent on flow from the adjacent property that enters through a culvert. After
seeing the site in a high rainfall season and a semi drought season I have concern that the
headwater reach will only be a wetland in "normal" conditions.
7) Flow is a concern on Powell, Morgan, Green, and Barker Branch's.

RE: Response to IRT comments on December 18, 2018 Field Meeting Minutes
Folly Swamp Mitigation Site, Gates County, NC
Pasquotank River Basin - 03020105
USACE Action ID No. SAW-2018-02026
Dear Mr. Barnes,
Wildlands received comments from Kyle Barnes and the NC IRT on December 6, 2019 on the Folly
Swamp Prospectus. This letter provides our responses to those comments.
Comments on Folly Swamp Prospectus
Kyle Barnes, USACE, December 6, 2019
1. The Pasquotank HUC is 02010205. The prospectus indicates the Pasquotank HUC as 03020105 in
multiple locations.
Thank you for noting that. We'll look to get it right in the mitigation plan.
2. Wetlands have been identified outside of the project area along Folly Swamp Reach 1. I have
concern that there may be a drainage effect on these adjacent wetlands.
Wildlands will install a groundwater gage(s) to monitor wetlands hydrology in this area before
and after construction to determine whether the stream design created a drainage effect. This
area will be identified in the preconstruction notification for an NWP 27. Additionally, Wildlands
will seek to minimize impacts to this area and conduct a wetlands delineation in the area by
MY5 to show that additional wetlands are created. Wildlands will offset any impacts to the
identified wetlands with onsite creation of floodplain wetlands.
3. The project as discussed will result in a significant amount of spoil and the needed area to
stockpile. Areas adjacent to Powell Branch and within the floodplain of the non -project area of
Folly Swamp have been identified as spoil stockpile areas. Removing vegetation and stockpiling
spoil within these areas are counter to the purpose of stream and wetland mitigation. These
areas should be avoided for spoil stockpiling because it removes or reduces existing
buffer/riparian area.
Wildlands Engineering, Inc. (P) 919.851.9986 • 312 West Millbrook Road, Suite 225 • Raleigh, NC 27609
The identification of spoil disposal locations included large blocks to evaluate jurisdictional
wetlands. Our intention is not to put spoil immediately adjacent to the conservation easement,
but we wanted to know where wetlands are present in the general areas. Wildlands will place
spoil in non -project areas (i.e., outside of CEs) such that the no negative effect on drainage is
created. If spoil placement causes runoff to enter the CE as concentrated flow, Wildlands will
include design measures to detain and diffuse the runoff.
Finally, Wildlands will be obtaining a no -rise certification for FEMA flood mapping so the spoil
must be placed outside of the 100-year floodplain limits.
Some concern for Morgan Branch. Stockpiling soil in the identified area only limits the function of
the buffer/riparian area outside of the project area.
See response above. A travel way is located between Folly Ditch and the proposed spoil area.
We will be targeting an area along NC 32 for spoil disposal and will keep it some distance from
Folly Ditch and the conservation easement. Any effect on drainage into the CE will be
ameliorated with design measures that promote runoff detention and diffusion.
5. Barker Branch: I have concern that the project will have issues with the owner/farmer when the
land outside of the easement becomes wetter. There needs to be a larger easement area to
prevent additional ditching and draining when the agricultural fields become too wet to farm.
We considered this when drafting the proposed conservation easement. The easement extends
more than 500 feet upstream from the start of stream credit. It also covers two ditches that
drain to Barker Branch. The valley rises quickly beyond the existing right bank so more of the
easement will be beyond the left bank. We will examine the proposed contours to determine if
the mitigation project would adversely affect agriculture. Due to wet conditions, the landowner
and farmer have low expectations, now and in the future, for crop yield from the field adjacent
to and southwest of the proposed CE.
In addition, installing the culvert to Greene Branch will remove flow from the ditch on the west
side of this field. Finally, we may widen the proposed CE if it appears doing so would include
agricultural land that will become unacceptably wet as a result of the project.
6. Green Branch: The headwater approach in upper Green Branch is a concern due to the fact that
it is fully dependent on flow from adjacent property that enters through a culvert. After seeing
the site in a high rainfall season and a semi drought season I have concern that the headwater
reach will only be a wetland in "normal" conditions.
We acknowledge your and Mac's concern. We will base our approach on the Outer Coastal Plain
Guidance and set performance standards accordingly. We will also monitor stream flow as well
as wetland hydrology and herbaceous plant communities.
Wildlands has visited several examples of the Coastal Plain headwater approach, including the
DMS Watts Site in Perquimans County, and the Nutrien Hell Swamp and Sage Gut Sites in
Beaufort County. These sites appear to be slowly showing a trend toward having stream
characteristics.
On the IRT site visit to Greene Branch in December 2018, Mac Haupt stated that, at this time,
the requirement for stream hydrology is 30 consecutive days of streamflow. This is confirmed by
the October 2016 IRT mitigation guidance. Mac suggested measuring streamflow with a camera
is probably the best method for a coastal plain headwater approach.
7. Flow is a concern on Powell, Morgan, Green, and Barker's Branch.
See the acknowledgement above. Flow is not expected to be an issue on Powell or Morgan
Branch due to the drainage area size. Barker Branch is known to have streamflow at nearly all
times according to the farmer.
We hope that these responses adequately address the IRT's comments. If not, feedback is requested as
we proceed into the mitigation plan phase.
Sincerely,
Chris Roessler

Chris,
I got in touch with our Coastal Management NCDOT field representative, and he agreed with us that
he wouldn't take jurisdiction of the canal that NC-32 crosses (bridge designated as C6). This means
that the mitigation site is not within CAMA jurisdiction and as such, no permitting is required from
us.
If you need anything else, feel free to contact me.

Chris,
I've read through the material, checked the site out on Google Earth and spoke with the CAMA Field
Rep for that area and it appears that the proposed mitigation sites are not within a CAMA
jurisdictional area. The canal that NC-32 goes over looks substantial, but as it heads east it appears
to disappear and transition to a flooded USACE 404 wetland swamp. I want to check with our NCDOT
Field Rep to see if he has ever made a jurisdictional call up there just to be sure.

Thanks, Ron. Sure thing on the details and info. I've attached the Prospectus main document and
figures.
Basically, we're developing a stream mitigation bank in Gates County, between Sunbury and
Cora pea ke.
We plan to work on six different streams and will be doing mostly restoration. Because we're not
including wetlands, our proposed approach is most commonly Priority 1.5. The idea is that we'll be
excavating a shallow floodplain below the existing floodplain. This will help to contain flooding within

Lastly, I reread this email... per the regulatory considerations, I agree, FEMA floodplain compliance is
applicable and maybe list the No -Rise or CLOMR are needed to resolve it. There is no official
documentation about it at this stage. I'm targeting end of August to submit the No-Rise/CLOMR
package. That should give us time to process all the comments, etc before construction.

Subject: Folly FEMA floodplain compliance
Hi Nicole-> One of the tables in the MP lists regulatory considerations and whether it is applicable
and resolved.
I'd say FEMA floodplain compliance is applicable and a no -rise certification is what we'd need to
resolve it.
Sorry if I've missed your communication about this but would you put any documentation you have
in this folder:
X:\Shared\Projects\005-45022 Folly Swamp\Reports\Mitigation Plan\Appendices\Appendix 5
Regulatory Correspondence
I recall you said you were working on iterations and it sounded like achieving no rise was doable.
Maybe we just
include a cover letter you're sending to the appropriate authority about this.
I think you mentioned we'd have to do a LOMR but it would mostly be a formality since it's about the
extent changing, no the elevation.

GATES COUNTY DRAINAGE DISTRICT #1
05/02/2019
This document summarizes discussions between Gates County Drainage District #1,
also known as Folly Ditch Watershed, and Wildlands Engineering.
Wildlands Engineering proposes to convert a portion of the drainage district's
maintained channels to wetlands areas. The areas to be involved include a portion of
the L.B Jordan property and the Jean C. Powell property, both of which are located on
Savage Rd., in Corapeake, NC.; said locations are in the Holly Grove Township of
Gates County, NC.
Discussion between Ronald Powell, Chairman, of Gates County Drainage District #1
and Wildlands Engineering project manager Chris Roessler have been ongoing to
address concerns about maintaining the ability of the channels to continue to allow
proper water flow for flood control_ The drainage district was established in the late
1950's, early 1960's through a federal project to reclaim farm lands and establish flood
control for the surrounding area. The parties acknowledge the following:
Wildlands will design the project such that it obtains a no -rise certification
from FEMA. This will indicate to the Gates County Drainage District #1
that the project, as modeled, should not cause a rise in flood elevation
greater than 0.1 feet.
Wildlands will conduct an as -built survey after construction that shows the
project was built according to the construction plans. This will confirm that
the no -rise condition will be valid.
The Gates County Drainage District #1 will not use heavy equipment or
motorized vehicles within the project area without first consulting with
Wildlands during the mitigation project life and the long-term manager
after that time. The mitigation project is expected to close out seven years
after construction. Unique Places to Save, LLC is expected to be the long-
term .manager_
Wildlands will clear flow obstructions while it is involved with the project.
Afterwards, it will be up to the Drainage District to do that if deemed
necessary. This should be done with chain saws and hand labor to the
extent possible. This can be done without contacting the long-term
manager provided heavy equipment or motorized vehicles are not used.
A design goal of the projects is to include positive slope on the stream
valleys. This will enable floods to continue moving downstream even if the
stream channel(s) is obstructed.

Component/Feature
Maintenance through project close-out
Routine channel maintenance and repair activities may include chinking of in -stream
structures to prevent piping, securing of loose coir matting, and supplemental
Stream
installations of live stakes and other target vegetation along the channel. Areas where
storm water and floodplain flows intercept the channel may also require maintenance to
prevent bank erosion. Beaver dams that inundate the stream channels shall be removed
and the beaver shall be trapped.
Vegetation shall be maintained to ensure the health and vigor of the targeted
community. Routine vegetation maintenance and repair activities may include
Vegetation
supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species
shall be controlled by mechanical and/or chemical methods. Any vegetation control
requiring herbicide application will be performed in accordance with NC Department of
Agriculture (NCDA) rules and regulations.
Site boundaries shall be identified in the field to ensure clear distinction between the
mitigation site and adjacent properties. Boundaries may be identified by fence, marker,
Site boundary
bollard, post, tree -blazing, or other means as allowed by site conditions and/or

Credit Release Schedule
1.0 Credit Release Schedule
All credit releases will be based on the total credit generated as reported by the as -built survey of the
Site. Under no circumstances shall any mitigation project be debited until the necessary DA
authorization has been received for its construction or the District Engineer (DE) has otherwise provided
written approval for the project in the case where no DA authorization is required for construction of
the mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if
performance standards have been satisfied sufficiently to meet the requirements of the release
schedules below. In cases where some performance standards have not been met, credits may still be
released depending on the specifics of the case. Monitoring may be required to restart or be extended,
depending on the extent to which the site fails to meet the specified performance standard. The release
of project credits will be subject to the criteria described as follows:

. 10% of credits will be reserved for the site that can be subsequently released after four bankfull events have
occurred in separate monitoring years, provided that the channel is stable and all other performance standards are
being met.
1.1 Initial Allocation of Released Credits
The initial allocation of released credits is defined as Bank Establishment in the 2016 Wilmington District
credit release schedule guidance document. The initial allocation can be released without prior written
approval of the DE upon satisfactory completion of the following activities:
a. Execution of the UMBI by the Sponsor and the USACE
b. Approval of the Final Mitigation Plan
c. Recordation of the conservation easement, as well as delivery of a title opinion that is
acceptable to the USACE.
d. Delivery of the financial assurances described in the Mitigation Plan.
e. 404 permit verification for construction of the site, if required.
1.2 Subsequent Credit Releases
All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a
determination that required performance standards have been achieved. For stream projects, a reserve
of 10% of a site's total stream credits shall be released after four bankfull events have occurred in separate
years, provided the channel is stable and all other performance standards are met. In the event that less
than four bankfull events occur during the monitoring period, release of these reserve credits shall be at
the discretion of the IRT. As projects approach milestones associated with the credit release, Wildlands
will submit a request for credit release to the DE along with documentation substantiating achievement
of criteria required for release to occur. This documentation will be included with the annual monitoring
report.

AGREEMENT TO ESTABLISH THE WILDLANDS PASQUOTANK
UMBRELLA MITIGATION BANK IN THE PASQUOTANK RIVER
BASIN WITHIN THE STATE OF NORTH CAROLINA
USACE approval of this Instrument constitutes the regulatory approval required for
the Wildlands Pasquotank Umbrella Mitigation Bank to be used to provide
compensatory mitigation for Department of the Army permits pursuant to 33 C.P.R.
332.8(a)(1). This Instrument is not a contract between the Sponsor or Property Owner
and USACE or any other agency of the federal government. Any dispute arising under
this Instrument will not give rise to any claim by the Sponsor or Property Owner for
monetary damages. This provision is controlling notwithstanding any other provision
or statement in the Instrument to the contrary.
This Umbrella Mitigation Banking Instrument (UMBI) is made and entered into on
the day of , 20 , by Wildlands Holdings VI, Inc., hereinafter Sponsor, and
the U.S. Army Corps of Engineers (Corps), and each of the following agencies,
upon its execution of this UMBI; the Environmental Protection Agency (EPA), the
U.S. Fish and Wildlife Service (FWS), the National Marine Fisheries Service
(NMFS), the North Carolina Wildlife Resources Commission (NCWRC), the State
Historic Preservation Office (SHPO) and the North Carolina Division of Water
Resources (NCDWR). The Corps, together with the State and Federal agencies that
execute this UMBI, arehereinafter collectively referred to as the Interagency Review
Team (IRT).
WHEREAS the purpose of this agreement is to establish an umbrella mitigation bank
(Bank) providing compensatory mitigation for unavoidable wetland and/or stream impacts
separately authorized by Section 404 Clean Water Act permits and /or Section 10 of the
Rivers and Harbors Act permits in appropriate circumstances;
WHEREAS the agencies comprising the IRT agree that the Bank site(s) is/are
suitable mitigation bank site(s), and that implementation of the Mitigation Plan(s) is/are
likely to result in net gains in wetland and/or stream functions at the Bank site(s), and
have therefore approved the Mitigation Plan(s);
THEREFORE, it is mutually agreed among the parties to this agreement that the
following provisions are adopted and will be implemented upon signature of this UMBI.
A. The Sponsor is responsible for assuring the success of the restoration, creation,
enhancement and preservation activities at the Bank site(s), and for the overall
operation and management of the Bank. The Sponsor assumes the legal
responsibility for providing the compensatory mitigation once a permittee secures
credits from the Sponsor and the District Engineer (DE) receives documentation that
confirms the Sponsor has accepted responsibility for providing the required
compensatory mitigation.
Version March 2020
B. The goals of the Umbrella Bank site(s) is/are to restore, enhance, create and
preserve wetland and/or stream systems and their functions to compensate
in appropriate circumstances for unavoidable wetland and/or stream impacts
authorized by Section 404 of the Clean Water Act permits and or Section 10
of the Rivers and Harbors Act permits in circumstances deemed appropriate
by the Corps after consultation, through the permit review process, with
members of the IRT.
C. Use of credits from the Bank to offset wetland and/or stream impacts authorized by
Clean Water Act permits must be in compliance with the Clean Water Act and
implementing regulations, including but not limited to the 404(b)(1) Guidelines, the
National Environmental Policy Act, and all other applicable Federal and State
legislation, rules and regulations. This agreement has been drafted in accordance
with the regulations for Compensatory Mitigation for Losses of Aquatic Resources
effective June 9, 2008 (33 CFR Parts 325 and 332) (Mitigation Rule).
D. The IRT shall be chaired by the DE of the U.S. Army Corps of Engineers, Wilmington
District (District). The IRT shall review documentation for the establishment of
mitigation bank sites. The IRT will also advise the DE in assessing monitoring reports,
recommending remedial measures, approving credit releases, and approving
modifications to this instrument. The IRT's role and responsibilities are more fully set
forth in Sections 332.8 of the Mitigation Rule. The IRT will work to reach consensus
on its actions.
E. The DE, after consultation with the appropriate Federal and State review agencies
through the permit review process, shall make final decisions concerning the amount
and type of compensatory mitigation to be required for unavoidable, permitted
wetland and/or stream impacts, and whether or not the use of credits from the Bankis
appropriate to offset those impacts. In the case of permit applications and
compensatory mitigation required solely under the Section 401 Water Quality
Certification rules of North Carolina, the NCDWR will determine the amount of credits
that can be withdrawn from the Bank. Any credits used to offset impacts solely
authorized by Section 401 cannot be used for other impacts authorized under Section
404 of the Clean Water Act or Section 10 of the Rivers and Harbors Act.
F. The parties to this agreement understand that a watershed approach to
establish compensatory mitigation must be used to the extent appropriate
and practicable. Where practicable, in -kind compensatory mitigation is
preferred.
Section II: Geoaraahic Service Area
The Geographic Service Area (GSA) is the designated area within which the Umbrella
Bank is authorized to provide compensatory mitigation required by DA permits. The GSA
for this Bank shall include the Pasquotank Hydrologic Unit 03010205 in North Carolina.
Credits are to be used in the same HUC in which they were generated, and credits within
each HUC should be tracked on separate ledgers.
2
Version March 2020

C. Mitigation Plans submitted for inclusion in this bank must meet the requirements of
any District guidance that is current at the time the new site is submitted to the
District, including any updates made to monitoring requirements, credit releases,
long term management, or any other provisions that are required and/or specifically
addressed in the Mitigation Plan. The addition of any site to this instrument shall be
considered as a modification to this instrument and processed in accordance with
the procedures set forth in the Mitigation Rule.
D. The members of the IRT will be allowed reasonable access to the Property
for the purposes of inspection of the Property and compliance monitoring of
the Mitigation Plan.
Section IV: Reaortina
A. The Sponsor shall submit to the DE, for distribution to each member of the IRT,

Version March 2020
Section V: Remedial Action
A. The DE shall review the monitoring reports, as required in the Mitigation Plan(s),
and may, at any time, after consultation with the Sponsor and the IRT, direct the
Sponsor to take remedial action at the Bank site(s). Remedial action(s) required
by the DE shall be designed to achieve the performance standards as specified
in the Mitigation Plan(s). All remedial actions required under this section shall
include a work schedule and monitoring criteria that will take into account
physical and climactic conditions.
B. The Sponsor shall implement any remedial measures required pursuant tothe
above.
C. In the event the Sponsor determines that remedial action may be necessary to
achieve the required performance standards, it shall provide notice of such
proposed remedial action to all members of the IRT. No remedial actions shall be
taken without the concurrence of the DE, in consultation with the IRT.
A. Description of credit classifications and provisions pertaining to the use of those
credits shall be provided in the Mitigation Plan(s) to be included in this bank.
Credit classifications (e.g., cold water stream, cool water stream, warm water
stream, coastal wetlands, non -riparian wetlands, riparian non-riverine wetlands,
and riparian riverine wetlands) will be in accordance with current District guidance
at the time the Mitigation Plan is submitted to the District. In general, these
classifications will be used to determine if a particular credit qualifies as 1n- Kind"
mitigation. Exceptions to the use of "In -Kind" mitigation may be allowed at the
discretion of the permitting agencies on a case -by -case basis.
B. Wetland and stream compensation ratios are determined by the DE on a case -by -
case basis based on considerations of functions of the wetlands and/or streams
impacted, the severity of the wetland and/or stream impacts, the relative age of
the mitigation site, whether the compensatory mitigation is in -kind, and the
physical proximity of the wetland and/or stream impacts to the Bank Site.
C. Notwithstanding the above, all decisions concerning the appropriateness of using
credits from the Bank to offset impacts to waters and wetlands, as well as all
decisions concerning the amount and type of such credits to be used to offset
wetland and stream impacts authorized by Department of the Army permits, shall
be made by the DE, pursuant to Section 404 of the Clean Water Act and
implementing regulations and guidance. These decisions may include notice to
and consultation with the members of the IRT through the permit review process if
the DE determines this to be appropriate given the scope and nature of theimpact.

Mitigation Plan(s). The Sponsor shall provide financial assurances in a form
acceptable to the DE, sufficient to assure completion of all mitigation work, required
reporting and monitoring, and any remedial work required pursuant to this UMBI.
The financial assurance value should be based on the cost of doing the mitigation
work, including costs for land acquisition, planning and engineering, legal fees,
mobilization, construction, and monitoring. For preservation only Bank Sites, no
financial assurances will generally be required unless there are specific activities
necessary to ensure the successful preservation of resources on the site, in which
case appropriate financial assurances may still be required.
B. All financial assurances shall be made payable to a standby trust or to a third -

DE, sufficient to protect the Bank Site(s) in perpetuity. The CE shall be perpetual,
preserve all natural areas, and prohibit all use of the property inconsistent with its
use as mitigation property, including any activity that would materially alter the
biological integrity or functional and educational value of wetlands or streams
within the Bank Site, consistent with the Mitigation Plan. The purpose of the CEwill
be to assure that future use of the Bank Site will result in the restoration,
protection, maintenance and enhancement of wetland and/or stream functions
described in the Mitigation Plan. The name and contact information for the Corps
approved easement holder and a draft copy of the CE will be provided in the site -
specific Mitigation Plan(s).
B. The Sponsor shall deliver a title opinion acceptable to the DE covering the
mitigation property. The property shall be free and clear of any encumbrances that
would conflict with its use as mitigation, including, but not limited to, any liens that
have priority over the recorded CE.
C. Subsequent to the recording of the CE, the Sponsor may convey the Bank Site
property either in fee or by granting an easement to a qualified land trust, state
agency, or other appropriate nonprofit organization approved by the Corps. The
Sponsor is responsible for ensuring that the CE is re -recorded so that it remains
within the chain of title. The terms and conditions of this conveyance shall not
conflict with the intent and provisions of the CE nor shall such conveyance enlarge
or modify the uses specified in the easement. The CE must contain a provision
requiring 60 day advance notification to the DE before any action is taken to void or
modify the CE, including transfer of title to, or establishment of any other legal
claims over, the project site.
Section XI: Lona-term Manaaement
A. The Sponsor shall implement the long-term management plan as described in
the site- specific Mitigation Plan(s). Unique Places to Save is responsible for
long-term management. They may be reached at: P.O. Box 1183; Chapel Hill,
NC 27514-1183; info(a)unigueplacestosave.org; and
https://www.uniqueplacestosave.org/contact .
B. The long-term management plan will include a list of annual maintenance,
monitoring, and/or repair activities for the/each mitigation site, the associated
annual cost for each activity, and the required total amount necessary to provide
all future site management. The long-term management plan should explain how
the funds will be managed and provided to the designated long-term manager
(e.g., an endowment managed through a separate account holder). The long- term
management plan should include a contingency section that addresses how the
responsibility and funding for the long-term site management will be passed on to
a new manager in the event that the selected long-term management entity is no
7
Version March 2020
longer able to provide for management of the site.
A. It is agreed to establish and maintain the Bank site(s) until (i) credits have been
exhausted or banking activity is voluntarily terminated with written notice by the
Sponsor provided to the DE and other members of the IRT; and (ii) it has been
determined and agreed upon by the DE and IRT that the debited Bank site has
satisfied all the conditions herein and in the Mitigation Plan. If the DE determines
that the Bank site is not meeting performance standards or complying with the
terms of the instrument, appropriate action will be taken. Such actions mayinclude,
but are not limited to, suspending credit sales, adaptive management, decreasing
available credits, utilizing financial assurances, and terminating the instrument.
B. As projects developed as part of this bank are specifically intended to restore
streams and/or wetland systems that are subject to periodic flooding and drought
conditions, they should be designed to withstand any such events that are
anticipated to occur in the natural environment. This is not limited to routine or
minor flooding or droughts, but also specifically includes flooding events resulting
from hurricanes, or other extreme weather events as well as extended periods of
drought. Additionally, this includes conditions resulting from sea level rise that
adversely impact projects that are part of this bank.
C. Any delay or failure of Bank Sponsor shall not constitute a default hereunder if and
to the extent that such delay or failure is primarily caused by any act, event or
conditions beyond the Sponsor's reasonable control and significantly adversely
affects its ability to perform its obligations hereunder including: (i) acts of God,
subject to the exceptions contained in Paragraph B above, lightning, earthquake,
fire, landslide, or interference by third parties; (ii) condemnation or other taking by
any governmental body; (iii) change in applicable law, regulation, rule, ordinance
or permit condition, or the interpretation or enforcement thereof; (iv) any order,
judgment, action or determination of any federal, state or local court, administrative
agency or government body; or (v) the suspension or interruption of any permit,
license, consent, authorization or approval. If the performance of the Bank
Sponsor is affected by any such event, Bank Sponsor shall give written notice
thereof to the IRT as soon as is reasonably practicable. If such event occurs before
the final availability of all credits for sale, the Sponsor shall take remedial action to
restore the property to its condition prior to such event, in a manner sufficient to
provide adequate mitigation to cover credits that were sold prior to such delay or
failure to compensate for impacts to waters, including wetlands, authorized by
Department of the Army permits. Such remedial action shall be taken by the
Sponsor only to the extent necessary and appropriate, as determined by the IRT.
D. At the end of the monitoring period, upon satisfaction of the performance
standards, the Sponsor may submit a request to the DE for site close out. The DE,
in consultation with the IRT, shall use best efforts to review and comment on the
request within 60 days of such submittal. If the DE determines the Sponsor has
achieved the performance standards in accordance with the mitigation plan and all
0
Version March 2020
obligations under this MBI, the DE shall issue a close out letter to the Sponsor.
