1 Introduction
1.1 Background
Water & Land Solutions, LLC (WLS) is submitting this mitigation plan for the Slowplay Mitigation Project
(“Project”), which will be a single bank site. The proposed Project is being developed as a private
commercial mitigation bank (“Bank”) located in the Catawba River Basin, 8-digit Hydrologic Unit Code
(HUC) 03050101 (Figure 1). The purpose of the Project is to provide stream mitigation credits to
compensate for unavoidable impacts to Waters of the U.S. (WOTUS) authorized under sections 401 and
404 of the Clean Water Act, Section 10 of the Rivers and Harbors Act, and all applicable state statutes.
The Project is providing 5,422.2 warm thermal regime stream mitigation credits. In addition, 19.73 acres
of easement will be protected in perpetuity.
This mitigation plan is prepared in accordance with C.F.R. §332.1-8 (2008), Compensatory Mitigation for
Losses of Aquatic Resources, and is based on current United States Army Corps of Engineers (USACE) –
Wilmington District Guidance, which is subject to the approval of the USACE District Engineer (DE) in
consultation with the North Carolina Inter-Agency Review Team (IRT).
1.2 Bank Sponsor
WLS will serve as the Bank sponsor for the Slowplay Mitigation Project. The contact information for the
sponsor is:
Water & Land Solutions, LLC
Attn: Catherine Roland
7721 Six Forks Rd, Suite 130
Raleigh, NC 27615
Phone: [phone]
Email: [e-mail]
1.3 Mitigation Goals and Objectives
The purpose of the proposed Bank is to generate compensatory mitigation credits in the Catawba River
Basin (HUC 03050101). The mitigation goals and objectives are based on the current resource condition
and functional uplift capacity of the project watersheds to improve and protect aquatic resources
comparable to stable reference stream systems within the Piedmont Physiographic Province. The
proposed Bank addresses the general watershed goals and restoration opportunities outlined in the
Catawba River Basin Restoration Priorities (RBRP; NCEEP, 2007, amended 2013). More specifically,
functional uplift goals will be accomplished by:
•Reducing sediment, soil erosion, turbidity, and nutrient inputs such as fecal coliform bacteria,
nitrogen, and phosphorus to the Catawba watershed.
•Promote nutrient and sediment reduction in agricultural areas by restoring and preserving
wetlands, streams, and riparian buffers.
•Improving riparian corridors and targeting restoration of impacted streams and riparian buffer
areas.
Draft Mitigation Plan
Slowplay Mitigation Project Page 2
To accomplish these goals, the following objectives will be measured to document overall project
success:
•Provide a floodplain connection to the incised Project stream reaches by lowering bank height
ratios (BHRs) to less than 1.2, thereby promoting more natural floodplain storage and overbank
flood flows.
•Improve bedform diversity by increasing scour pool to pool spacing and depth variability.
•Increase native species riparian buffer vegetation density/composition along streambank and
floodplain areas.
•Improve aquatic habitat through the addition of in-stream cover and native woody debris.
•Site protection through a 19.73-acre conservation easement with minimum 50-foot riparian
buffers from the top of banks along all streams in perpetuity.
The existing conditions site assessment suggests that the proposed mitigation activities will result in a
higher functioning aquatic ecosystem. The project goals and objectives address water quality stressors
by reducing nutrient and sediment inputs through stream and riparian buffer restoration. Raising the
local water table will improve hydrologic functions, and biologic and habitat functions will improve by
the revegetation of the riparian buffers.
2 Bank Establishment and Operation
2.1 Site Selection
The Project site (35.852430°, -81.148672°) is located in Alexander County, North Carolina (Figure 1). The
Project is in North Carolina Department of Environmental Quality (NCDEQ) sub-basin 03-08-32 within
the Catawba River Basin. The project reaches include three unnamed tributaries to the Lower Little
River, which drain into the Catawba River and ultimately Lake Norman. The Lower Little River and the
Catawba River are listed as WS-IV because they flow into Lake Norman, a water supply reservoir.
To access the site from Raleigh, NC, travel on I-40 West, take exit 131 to continue on I-40W towards I-
785 N/Greensboro/Winston-Salem. Follow signs for I-40/I-85BL S, continue on I-40/US-220 S, and then
follow signs for I-40 W/Winston-Salem. Take exit 148 for US-64/NC-90 towards Statesville/Taylorsville,
turn right onto NC-90 W/US-64 W/Taylorsville Hwy, and continue onto US-64 W. Turn left on McClain
Rd, in 0.9 miles turn right on Old Mountain Rd, then turn left onto Liberty Church Rd. After 1.3 miles
turn left on Millersville Rd, in 1.8 miles turn left on Paynes Dairy Rd, and then in 0.8 miles turn right on
Grassy Ridge Ln (35.852430°, -81.148672°).
2.2 Service Area
The proposed Geographic Service Area (GSA) is illustrated in Figure 2 and will provide compensatory
mitigation credits for unavoidable, permitted impacts to Waters of the United States in the Catawba
River Basin (8-Digit HUC 03050101). Use of approved mitigation credits from the bank to compensate
for impacts outside the GSA may be considered by USACE on a case-by-case basis. The Project will
provide compensatory mitigation for warm stream impacts.
Draft Mitigation Plan
Slowplay Mitigation Project Page 3
2.3 Site Protection Instrument
The Sponsor has obtained a legal option agreement to develop the mitigation project with a permanent
conservation easement for each of the parcels that make up the site. A copy of the agent authorization
form and conservation easement template are provided in Appendix D. The Sponsor shall record a
conservation easement with the Alexander County Register of Deeds that has been approved by the
USACE, in coordination with the IRT, and provide a copy of the recorded conservation easement to the
USACE. The current property owners for the Project site are listed in Table 1 below.
Table 1. Parcel Ownership Information
Owners of Record Parcel ID Number County Acres Deed Reference
Moose, Christina Herman 3767 21 4729 Alexander 159.266 655/1986
The conservation easement will ensure that the site will be protected in perpetuity from land uses that
are inconsistent with the Mitigation Banking Instrument (MBI). Apart from USACE-approved activities (in
coordination with the IRT), the site shall not be disturbed by activities that would adversely affect the
intended extent, condition, or function of the project. The conservation easement shall not be removed
or modified without prior written approval of the USACE.
2.4 Watershed Need and Feasibility
As a result of implementing this Bank, WLS will address restoration components as defined in the
Catawba River Basin Restoration Priorities (RBRP; NCEEP, 2007, amended 2013). To appropriately offset
unavoidable impacts to Waters of the United States associated with growth and development, the
proposed Bank will improve water quality and protect aquatic resource functions in this region.
The technical feasibility of the Project is assured due to WLS’ extensive experience with stream and
wetland mitigation in North Carolina and throughout the Southeast. Examples of WLS’ success with
stream and wetland restoration include the WLS Neuse 01 Umbrella Mitigation Bank and the WLS
Yadkin 01 Umbrella Mitigation Bank. The absence of fatal flaws, such as hydrologic trespass and absence
of threatened and endangered species and their habitats, means the project is unlikely to be impeded
by resource issues or by objections from landowners.
The Project mitigation goals are to provide water quality and ecological benefits within the Glade Creek-
Lower Little River and Catawba River watersheds. Major goals for the Catawba River basin, as described
in the Catawba River Basin Restoration Priorities (RBRP; NCEEP, 2007, amended 2013) include: 1)
improved management of stormwater runoff to Crowder and Catawba creeks, 2) protection of the
critical water supply reservoirs in the region and their immediate riparian zones, and 3) land protection
for important natural and cultural resource sites including the Bunker Hill bridge over Lyle Creek. The
Slowplay Mitigation Bank will restore aquatic habitats that are currently degraded by cattle access and
bank erosion, improve water quality by excluding cattle, restore riparian buffers, stabilize streams that
are part of a WS-IV watershed, serve to continue existing water quality initiatives that are on-going in
the watershed, and enhance/restore riparian wetlands by reconnecting the stream to its historic
floodplain.
Draft Mitigation Plan
Slowplay Mitigation Project Page 4
In the Catawba River Basin wide Water Quality Plan (NCDWQ, 2010), the Lower Little River Watershed
(0305010110, Figure 1) is specified for protection efforts that include headwater streams that drain to
Lookout Shoals Lake, a water supply reservoir for the city of Statesville. As part of the proposed Project,
approximately 7,314 linear feet of stream (warm water thermal regime) will be stabilized, enhanced,
and restored. The Lower Little River watershed is described as making a shift from agricultural land use
to small poultry farms. The proposed restoration work for the Project would restore riparian buffers at
least 50 feet in width along all stream reaches. This proposed work will provide significant reductions in
nutrients, sediment, and fecal coliform supplied to the Lower Little River, Lookout Shoals Lake, and
ultimately Lake Norman.
3 Baseline Information
WLS performed an existing conditions assessment for the site by compiling and analyzing baseline
information, aerial photography, and field data. The purpose of this assessment was to determine how
aquatic resource functions have been impacted within the catchment area. Parameters such as
watershed drainage area, percent impervious cover, land use, climate, and hydrology were evaluated.
The following sub-sections describe the existing site conditions, impairment, and primary controls that
were considered for developing an appropriate restoration design approach.
3.1 Watershed Characterization
3.1.1 Surface Water Classification
The project site is situated within the Glade Creek - Lower Little River watershed in the southeastern
portion of Alexander County, NC. The project reaches include unnamed tributaries to Lower Little River.
The reaches on the Project flow southwest into an unnamed tributary. The unnamed tributary flows
south approximately 0.7 miles to its confluence with the Lower Little River. The Little River then flows
directly into the Catawba River approximately one mile downstream. The Glade Creek- Lower Little River
watershed is classified by the NCDEQ Division of Water Resources as ‘C’ and ‘WS-IV’ (Aquatic Life, Water
Supply) waters within the project area downstream to its confluence with the Catawba River.
3.1.2 Jurisdictional WOTUS
WLS investigated on-site jurisdictional WOTUS using the USACE Routine On-Site Determination Method.
This method is defined in the 1987 USACE Wetlands Delineation Manual and subsequent Eastern
Mountain and Piedmont Regional Supplement. Stream classification utilized the North Carolina Division
of Water Quality (NCDWQ) Stream Identification Form. Potential jurisdictional (JD) wetland areas as well
as upland areas were classified using the USACE Wetland Determination Data Form. The results of the
on-site field investigation indicated that all Project reaches were determined to be jurisdictional stream
channels. In addition, seven jurisdictional wetland areas were delineated within the proposed Project
area (Figure 8). WLS submitted a preliminary jurisdictional determination (PJD) request to the USACE in
January 2024 and attended a site visit with Mitchell Anderson (USACE) on March 6, 2024. WLS has not
received a concurrence email or PJD but expects to have the official documentation included in the Final
Mitigation Plan. Appendix F contains a copy of the submitted PJD and correspondence with Mitchell
Anderson.

Slowplay Mitigation Project Page 5
3.1.3 NC SAM and NC WAM
WLS completed stream and wetland assessments using the NC Wetland Assessment Method (NC WAM,
Version 5.0, 2015) and NC Stream Assessment Method (NC SAM, Version 2.1, 2015). WLS evaluated the
NC WAM and NC SAM metrics relevant to the Project wetland areas and stream reaches (See Appendix
E). The Project reaches S100-R1, S100-R2, S100-R3, S103, S105, and S201 all scored ‘low’ due to incised
channels, lack of buffer, and water quality stressors from agriculture. Reaches S101, S102, S104, S200-
R1/R2 and S300 all scored “medium” due to wider buffers. S100-R4 scored “high” due to a more stable
channel, wider buffers, and more established in-stream habitat. Wetland areas W01 through W07 all
scored “low” due to heavy alteration from cow access. The ecological assessments also incorporated
qualitative and quantitative observations using historic aerials, field evaluations, and detailed
topographic survey data collected across the site. The conclusions from these assessments help describe
the current stream and wetland conditions and functional ratings, however, these methods are not
intended for determining mitigation success on the site.

3.2 Land Use and Development Trends
The Glade Creek watershed is primarily agricultural, forested, and low density residential land use. The
Project will protect the wildlife corridor and protect aquatic and terrestrial habitat in the Project area
through a permanent conservation easement (Figure 9). Currently, the project area consists of mostly
pasture (hay and grass) with sparse riparian buffers. A review of topographic maps, field investigations
of on-site soils and stream/wetland conditions, and LiDAR survey data provides clear evidence that the
valley morphology and catchments support a Piedmont stream and riparian wetland system.
The surrounding areas remain a largely agricultural community with some neighboring forested
property and low-density home sites. US Census data indicate the community of Taylorsville, NC has
been very slowly increasing in population for the past several years. Based on historic aerial photo
review and development data, the project area and watershed has not appreciably changed or
developed in several decades and will likely remain in dominant agricultural use for the foreseeable
future.
Draft Mitigation Plan
Slowplay Mitigation Project Page 6
3.3 Landscape Characteristics
3.3.1 Physiography and Geology
The Project site is in the Northern Inner Piedmont (45e) Level IV Ecoregion (Griffith et al., 2002). The
Northern Inner Piedmont is characterized by higher elevations, more rugged topography, and mountain
outliers than other areas of the Piedmont (Griffith et al., 2002). Geologically, the Bank area consists of
Biotite Gneiss and Schist (‘CZbg’) (NC Geological Survey, Geologic Map of North Carolina, NCDNR 1985).
Gneiss, schist, and granite are typical rock types, covered with deep saprolite and mostly red, clayey
subsoils (Griffith et al., 2002).
3.3.2 Soils
As shown on the NRCS Soils Map (Figure 4), existing floodplain soils surrounding the project reaches are
within the mapping units RdE (Rhodhiss sandy loam), FcD2 (Fairview sandy loam), and FcC2 (Fairview
sandy clay loam). Rhodhiss sandy loam soils comprise the majority of the easement, which are not
frequently flooded and have 25 to 45 percent slopes. Fairview soil, which comprises the top portion of
S100-R1, is also is not frequently flooded and has a 15 to 25 percent slope.
3.3.3 Climate
Alexander County is generally hot and humid for long periods in the summer, and winter is cool and
fairly short (NRCS, 1995). The average growing season for the Project site is 250 days, beginning March
16th and ending November 21st (Taylorsville, NC WETS table). The average annual precipitation in the
Project area is approximately 55.34 inches with a consistent monthly distribution, except for convective
storm events or hurricanes that occur during the summer and fall months. Over the past 48 months, the
rain gauge at the Taylorsville station, approximately 4.8 miles north of the Project site, has recorded
231.89 inches of rain (NRCS).
3.3.4 Existing Vegetation
The current and historic use surrounding the Project area has been primarily for agriculture purposes and
is currently an active cattle pasture. The project is a mix of hardwood forested areas with cattle access
and open grass pastures. Prior to anthropogenic land disturbances, the riparian vegetation community
likely consisted of Mesic Mixed Forest (Piedmont subtype) (Schafale, 2012).
Agricultural Fields: Currently, most field areas surrounding the Project area are used as livestock
pasture. The Project area is a mix of forested and open pasture and one farm pond (S100-R1) with
unrestricted cattle access to all stream reaches. Red fescue (Festuca rubra) dominates this area along
with dogfennel (Eupatorium capillifolium), blackberry (Rubus sp.), multiflora rose (Rosa multiflora), and
broomsedge (Andropogon virginicus).
Mixed Hardwood Forest: The wooded portion of the Project area is a mix of scrub pine and mixed
hardwood forests along the hillsides of the stream buffer zones. Areas dominated by pines include white
pine (Pinus strobus) and Virginia pine (Pinus virginiana), with a shrub and herbaceous layer consisting of
blackberry (Rubus sp.) and broomsedge. Mixed hardwood forests on the Project are dominated by tulip
poplar (Liriodendron tulipifera), river birch (Betula nigra), red maple (Acer rubrum), American beech
(Fagus grandifolia), white oak (Quercus alba), blackgum (Nyssa sylvatica), black willow (Salix nigra), and
Draft Mitigation Plan
Slowplay Mitigation Project Page 7
white pine in the canopy. The shrub layer includes American holly (Ilex opaca), ironwood (Carpinus
caroliniana), Chinese privet (Lingustrum sinense), and multiflora rose. Herbaceous cover in the mixed
mesic forest is limited but includes Christmas fern (Polystichum acrostichoides), Japanese honeysuckle
(Lonicera japonica), mayapple (Podophyllum peltatum), and red fescue.
Invasive Species Vegetation: There is not a significant presence of invasive species vegetation in the
Project area. There are sparse occurrences (totaling less than five percent) of multiflora rose and
Chinese privet located in existing riparian buffers. A small cluster of kudzu (Pueraria montana)is present
outside of the proposed easement located above S201. Invasive vegetation will be treated during
construction activities. After restoration, these areas will be monitored, and any invasive plants found
within the project boundary will be treated to prevent expansion and establishment of a substantial
invasive community. This will allow for native riparian and upland plant communities to establish.

3.4 Existing Stream Conditions
3.4.1 Geomorphic Assessment
WLS conducted geomorphic and ecological assessments of the Project reaches to determine the current
stream function, channel stability, and the impact of past and current land use on the Project site’s
aquatic resources. From historical aerial research, evidence was found to demonstrate that most of the
Project area has been heavily impacted from historic and current land use practices. A further review of
topographic maps, field investigation of on-site features, similar stream reference conditions, and LiDAR

imagery (Figure 5) provides clear evidence that the existing channel patterns appear to be indicative of
valley signatures, valley slopes, and drainage basins that support stream and wetland systems with
associated bottomland hardwood forest.
The streams at the Project were broken down into thirteen reaches (S100-R1, S100-R2, S100-R3, S100-
R4, S101, S102, S103, S104, S105, S200-R1, S200-R2, S201, and S300) totaling approximately 7,314 linear
feet of existing streams. Field evaluations determined that project reaches S100-R2, S100-R3, S100-R4,
S200-R1, S200-R2, and S300 are perennial streams and reaches S100-R1, S101, S102, S103, S104, S105,
and S201 are intermittent. Table 4 provides reach designations, approximate drainage areas, stream
status based on field analyses, and NCDWQ stream classification form scores.

The existing project streams have been degraded as a result of historic and current land use practices,
including agriculture and silviculture. Livestock access to the streams has severely impacted the
streambanks along some of the project stream reaches. The project streams are incised and unstable,
with associated bank erosion. Clearing and ditching of stream buffers for agricultural purposes has
removed or reduced high functioning riparian buffers. Currently, the project reaches act as significant
sources of sediment and nutrient contamination to downstream waters. Table 5 characterizes the

3.4.2 Existing Reach Descriptions
S100-R1: Reach S100-R1 begins at the northeast boundary of the project as a headwater seep. The
channel is ill-defined and is impacted by the
backwater of a small pond. S100-R1 is heavily
impacted by cattle using it for wallowing and a
drinking source. The reach lacks riparian buffer and is
dominated by pasture grasses and weeds. Large trees
are present along the banks of the upper portion of
S100-R1. S100-R1 is bisected by a fence line that runs
across the reach before transitioning to a pond.
Below the pond dam, S100-R1 continues down the
valley to its connection with S100-R2. The channel
exhibits widespread channel instability and erosion
due to a lack of riparian buffer and direct cattle
access. The biological function of the stream has
been severely impacted by sedimentation and
Ponded area at the top of S100-R1. Pond has
cattle access and agricultural runoff.

Slowplay Mitigation Project Page 10
habitat degradation. Reach S100-R1 transitions into Reach S100-R2 as the channel conditions and
mitigation approach change.
S100-R2: Reach S100-R2 starts below S100-R1.
Most of this reach is stable due to the presence of
a thin riparian buffer and bedrock in the stream
with several small cascade features. Cattle have
access to most of this reach. However, due to
access constraints of topography, the geomorphic
impacts from cattle are minimal. Channel banks are
mostly stable with minor areas of bank erosion.
Due to cattle access within the reach and from
reaches above, the biological function of the
stream has been severely impacted through
sedimentation and habitat degradation. Reach
S100-R2 transitions into S100-R3 as the channel
conditions change.
S100-R3: Reach S100-R3 is a short, severely incised, and entrenched stream section downstream of
S100-R2. As with S100-R1, S100-R3 has experienced stressors associated with agricultural practices, such
as cattle access and timbering. Most of the stream banks are vertical with many areas of mass wasting
present. Along the right terrace, the riparian buffer has been disturbed and is dominated by small pines
and invasive species. The riparian buffer on the left is dominated by a mature hardwood forest. The
reach terminates below a large culvert crossing that will be removed as it transitions into S100-R4.
S100-R4: Reach S100-R4 starts downstream of S100-R3. Similar to S100-R2, this reach is mostly stable
with some minor areas of channel instability and bank erosion. Cattle have access to this reach, but
generally do not use these areas of the property. Due to cattle access within the reach and from reaches
upstream, the biological function of the stream has been severely impacted through sedimentation and
habitat degradation. Reach S100-R4 ends with its confluence with S300.
S101: Reach S101 starts close to the southeast corner
of the project. This can be generally characterized as a
gravel-dominated transport channel that is spring fed
with significant channel incision, severe
entrenchment, and undergoing many of the same
channel evolution processes as S100-R1. In many
areas of the stream, bank heights exceed five feet.
Eroding and vertical banks are common throughout
this reach. S101 has experienced stressors associated
with agricultural practices, such as cattle access and
timbering. The entirety of the reach is dominated by a
thin riparian buffer, sparse trees, and invasive species.
Reach S101 ends with its confluence with S100-R3.
S102: Reach S102 is a small headwater tributary that
starts as a groundwater seep and flows into S101. This short reach is characterized as a severely incised
Bedrock seen on S100-R2.

and entrenched stream. The stream is experiencing the same channel evolutionary processes as S101
from current and past agricultural practices, such as cattle access and timbering. The entirety of the
reach is dominated by a small riparian buffer, sparse trees, and invasive species. Reach S102 ends with
its confluence with S101.
S103 and S105: Both reach S103 and S105 begin
as small headwater seeps. The landowner has
used these reaches as a place for dumping farm
waste. The upper half of both reaches are
severely incised and entrenched but are
dominated by in-channel bedrock. Both reaches
have cattle access and the lower half of each
reach is used primarily by cattle as a wallowing
hole and drinking source. Therefore these
sections lack defined bed and bank. Both S103
and S105 lack riparian buffers and are dominated
by pasture grasses and weeds. Due to cattle
access within the reaches, the biological function
of the streams have been severely impacted
through sedimentation and habitat degradation. Both S103 and S105 end at their confluence with S100-
R1.
S104: Reach S104 begins as a small headwater seep to the south of S103. This reach is moderately stable
with some areas of bank erosion. The presence of bedrock in the stream along with mature woody
vegetation along the stream bank has helped to maintain both stream channel and bank stability
throughout. The entire reach has cattle access. However, due to topographic constraints and presence
of bedrock, cattle impact has been limited. The reach has some woody vegetation but lacks a mature
riparian buffer. Due to cattle access within the reach the biological function of the stream has been
impacted through sedimentation and habitat degradation. S104 ends at its confluence with S100-R1.
S200-R1/R2: Reach S200-R1 begins at a large
headcut at the northwest corner of the project.
S200-R1 is severely incised and entrenched and has
experienced stressors associated with agricultural
practices, such as cattle access and timbering. Most
of the stream banks are vertical and eroding with
some areas of lower banks and channel bed stability.
A culvert crossing towards the lower end of the reach
has caused a backwater effect in the stream resulting
in an overly wide channel, large amounts of fine
sediment, and diminished transport capability. Below
the culvert the reach exhibits similar attributes to the
upper part of the reach. The riparian buffer is
dominated by a mature hardwood forest with a less
mature buffer along the left valley. The biological function of the stream has been severely impacted by
sedimentation and habitat degradation resulting from bank erosion and cattle access. Below the
Reach S103 bank erosion. Cattle have access
to this reach.
Reach S200-R1 bank erosion.

Slowplay Mitigation Project Page 12
confluence of S200 and S201 there is a short, severely incised, and entrenched stream section. The
stream banks are vertical and eroding with areas of mass wasting. S200-R1 ends and S200-R2 begins at
the bottom of this highly eroded area. The beginning of S200-R2 marks a change in the valley
characteristics, as the valley becomes less confined and valley slopes are lower in this reach. The riparian
buffer is dominated on the right valley by a mature hardwood forest with a less mature buffer along the
left valley. The biological function of the stream has been severely impacted by sedimentation and
habitat degradation resulting from bank erosion and direct cattle access. The lower 150 feet of this
reach is somewhat stable with low banks. This is a direct result of historically rerouting the stream at
the downstream terminus of the project away from the natural valley. Reach S200-R2 terminates at the
property boundary.
S201: Reach S201 is a short headwater tributary east of S200. The farmer has used the upper portion of
this reach as a dump for farm waste. Headcuts have formed causing severe incision and entrenchment.
Channel evolution has allowed for some areas of bed and bank stability at a lower floodplain elevation.
However, much of the reach is experiencing vertical banks and erosion. The riparian buffer is dominated
on both sides by a mixture of pasture and some large hardwood vegetation. Cattle have access to the
stream throughout. As a result of cattle access, the biological function of the stream has been severely
impacted by sedimentation and habitat degradation.
S300: Reach S300 is a segment of a large unnamed
tributary at the southwestern boundary of the
property. The majority of this reach is incised and
slightly entrenched. Outside meander bends are
characterized by tall vertical and bare eroding banks.
The channel is overly wide which results in poor
transport capabilities of its gravel dominated
substrate. Mid channel bars are evidence of the
streams inability to transport its sediment properly.
The riparian buffer is dominated by pasture
immediately adjacent to the stream with a mature
hardwood forest farther away from the stream. The
biological function of the stream has been severely
impacted by sedimentation and habitat degradation
resulting from bank erosion and direct cattle access. Reach S300 ends at the property boundary.
3.4.3 Sediment Supply, Delivery and Storage
Project streams were characterized using pebble counts within stable riffles and were visually inspected
for sediment impacts or large sediment deposits. Fine sediment inputs to the stream were evident in
some areas of the project, but in general the project streams were capable of transporting all fine
sediments. Large fine sediment deposits were not noted except in locations where back water
conditions were present (above culverts or the farm pond and at the confluence of S100-R4 and S300).
Field investigations suggest the sediment supply along the project streams is recruited predominantly
from streambank erosion along the stream reaches, livestock access to the stream, and general
sediment inputs from the adjacent livestock pastureland use. The proposed design addresses the
sediment issues within the project streams. The exclusion of livestock from the conservation easement,
Reach S300 bank erosion.
Draft Mitigation Plan
Slowplay Mitigation Project Page 13
revegetation of the riparian buffer, and stabilization or restoration of streambanks that are actively
eroding is expected to reduce the overall sediment inputs throughout the Project watershed. Crossings
are designed to pass large flow events (10-year recurrence) without backing up water within the reach.
Minimum slopes are maintained even within the flattest areas of the project to continue sediment
transport down the reach and prevent large deposits from aggrading in the project reaches.
3.5 Potential Site Constraints
3.5.1 Existing Easements on the Site
There are no known existing easements or potential site constraints on the project site.
3.5.2 Utility Corridors within the Site
There are no utility easements in the project area, and no significant constraints have been identified for
the project.
3.5.3 Easement Breaks
WLS coordinated stream crossing locations with the landowner and discussed keeping existing stream
crossings within the conservation easement as internal breaks. The landowner requested 60-foot wide
easement breaks at the stream crossings to allow unencumbered access for potential future
development. There are three external crossings on the project for landowner access: an existing culvert
crossing that will remain on S100-R1 below the existing pond, a culvert crossing on S100-R4, and a ford
crossing at the top of S101.
3.5.4 Aviation Facilities
Based on a review using Google Earth, the nearest airport to the project site is Alexander County
Airport, private grass airstrip located approximately 0.2 miles southeast of the Project. Also located
within a five-mile radius of the Project is the Brown Airport, a private grass airstrip located
approximately 3.6 miles north of the Project, and the Gryder-Teague Airport, a private grass airstrip
located approximately 4.7 miles north of the Project. In accordance with the FAA Advisory Circular (AC
No: 150/5200-33C), WLS will coordinate with the airports as required. WLS does not anticipate the
project to affect aviation. Project summary letters were sent by WLS via certified mail to all three airport
owners. Confirmation of no landowner concerns was acquired via email, verbally through phone call,
and/or no response to the letter by the specified date. Correspondence between WLS and the airport
owners can be found in Appendix G. There are no other aviation facilities within five miles of the Project
area.
3.5.5 Mineral or Water Rights Assurance
There are no known mineral or surface water rights issues within or adjacent to the site property.
3.5.6 FEMA Floodplain Compliance and Hydrologic Trespass
Review of the Federal Emergency Management Agency’s (FEMA) National Flood Insurance Program’s

and S200 are not regulated waters (Figure 6). There are no established Base Flood Elevations (BFEs),
Floodways, or Flood Hazard Zones along the tributaries. However, S300 is within the flood hazard zone
AE. The proposed Enhancement II work associated with this project reach includes structure placement
and excavation within the Flood Hazard Zone. After phone discussions with the Alexander County
Floodplain Administrator, the proposed work was deemed significant enough to require an engineering
study and application for an Alexander County Floodplain Development permit. FEMA permitting
coordination is ongoing with the Alexander County Floodplain Administrator. Significant changes to the
work along S300 as depicted in the Plans (Appendix A) are not anticipated after coordination with the
county floodplain administrator.
3.5.7 Invasive Species Vegetation
There are currently no substantial communities of invasive plant species within the proposed project
boundaries. Small populations of Chinese privet and multiflora rose were observed on the project site
along the reaches of S100 and S200. A small cluster of kudzu is present outside of the proposed
easement located above S201. These areas will be monitored by WLS, and any invasive plants found
within the project boundary will be treated to prevent expansion and establishment of a substantial
invasive community. This will allow for healthy, native riparian and upland plant communities to
dominate the area and help prevent future establishment of invasive species vegetation.
3.5.8 Potential Future Site Risk and Uncertainties
Future site risks and uncertainties include, but are not limited to, development, silviculture, livestock,
and infrastructure maintenance. Historic aerial imagery indicates that the Project has been used
extensively for livestock, agricultural, and silviculture purposes. The surrounding areas remain in an
agricultural community with some neighboring forested property and small home sites. Due to low
development potential, the project area will likely remain in agricultural use. There are some forested
areas surrounding the project area that could be used for silviculture or logging operations. There is also
potential for the area surrounding the easement to be developed in the future. The project area is not
adjacent to any roads that might need future maintenance. Project streams were designed to be self-
maintaining and resilient in a dynamic landscape. Riparian buffers of 50 feet in many areas of the project
will protect the project reaches and wetland areas from changes in watershed hydrologic regimes.
3.6 Regulatory Considerations
3.6.1 Cultural Resources
The Project is not anticipated to have any adverse impacts on cultural or historic resources. There are no
sites currently listed on the National Register of Historic Places (NRHP) within the Project area. The
nearest site is the Alspaugh Cotton Mill (HPO Site ID: AX0003) which is approximately 1.8 miles from the
Project site. On-site investigations and discussions with the landowners have not disclosed any potential
resources or occurrences on the property. Therefore, the proposed Project activities should have no
effect on any historic properties eligible for listing in the National Register, and the State Historic
Preservation Office (SHPO) did not have any comments.
Draft Mitigation Plan
Slowplay Mitigation Project Page 15
3.6.2 Threatened and Endangered Species
Based on a review of the US Fish and Wildlife Service (USFWS) database and IPaC, there is currently one
federally listed endangered species that may occur within the Project boundary, Northern long-eared
bat (Myotis septentrionalis), and one proposed endangered species, Tricolored Bat (Perimyotis
subflavus). There are also two threatened species: Dwarf-flowered heartleaf (Hexastylis naniflora) and
Bog turtle (Glyptemys muhlenbergii). No other potential protected species occurrences were observed
during site investigations. Project implementation is not anticipated to have a negative impact on any of
these species. Agency correspondence can be found in Appendix G.
3.6.3 Conditions Affecting Hydrology
Three farm crossings (two culvert and one ford) will be accounted for in the stream design (Figure 9).
These crossings will allow livestock and farm equipment to access fields and pastures on either side of
the stream reaches. To ensure stream stability, the crossings will be replaced with appropriately sized
pipes set at the correct elevations to promote stability and allow aquatic organism passage. Stabilization
practices will be applied to ensure stable crossings. The ponds at the top of S100-R1 will be dewatered,
and a step-pool channel will be designed down the center of the valley reconnecting the stream to a
natural floodplain.
3.6.4 Adjacent Land Use
Project-adjacent land use is primarily cattle pasture. The project is designed to protect aquatic features
from cattle impacts.
4 Functional Uplift Potential
Harman et al. (2012) provides a framework for conducting function-based assessments to develop
project goals and objectives based on a site’s restoration potential and functional uplift. The framework
is based on the Stream Functions Pyramid (SFP) which is a conceptual model that can be used to help
define project goals and objectives by linking them to stream functions. Stream functions are separated
into a hierarchy of functions and structural measures, ranging from Level 1 to Level 5 and include the
following functional categories: Hydrology (Level 1), Hydraulic (Level 2), Geomorphic (Level 3),
Physiochemical (Level 4), and Biological (Level 5). Function-based goals and objectives were considered
that relate restoration activities to the appropriate parameters from the SFP framework, which are
based on existing conditions, site constraints, and overall restoration potential. To accomplish these
site-specific goals, the following functional objectives will be measured to document overall project
success as described in Table 6.

4.1.1 Restoration Potential and Project Benefits Summary
Restoration projects commonly provide functional lift of Level 2 and 3 parameters. To achieve goals in
Levels 4 and 5, a combination of reach scale restoration and upstream watershed health must be
measurable and sustainable. It is expected the Project will reduce pollutant loads, including sediment
and nutrients, improving overall aquatic functions. Given the landscape position and catchment size, the
restoration activities will likely provide functional lift within the physiochemical and biological functional
categories.
The Project will provide numerous water quality and ecological benefits within the watershed. While
many of these benefits focus on the Project area, others, such as nutrient removal, sediment reduction,
and improved aquatic and terrestrial habitat, have more far-reaching effects that extend downstream.
The expected project benefits and ecological improvements are summarized in Table 7.

6 Mitigation Work Plan
The project will involve the restoration of nine reaches (S100-R1, S100-R3, S101, S102, S103, S105, S200-
R1, S200-R2 and S201) totaling approximately 4,562 linear feet of stream (Figure 9). An additional four
reaches (S100-R2, S100-R4, S104, and S300) totaling 2,436 linear feet of stream will receive
enhancement level II stream work. The design approach utilizes common mitigation practices and will
appropriately address the jurisdictional streams at the site, including protecting or enhancing riparian
buffers and riparian wetlands along all the Project stream reaches, providing the maximum functional
uplift with the goal of improving aquatic functions to a degraded resource. The design approach and
mitigation work plan are described in the following subsections.
6.1 Design Approach
The Project appropriately addresses all the jurisdictional stream reaches at the project site, including
restoring riparian buffers along all the project stream reaches currently in agriculture, and enhancing
and preserving riparian wetlands. The restoration project reaches are unstable, with extensive incision,
channel downcutting/widening, and stream bank erosion. Many of the disturbed riparian buffers are
completely or partially cleared. The proposed project will provide adequate floodplain access to all
stream reaches. Priority Level I Restoration is proposed to reconnect the project streams with their
geomorphic floodplains. Priority II Restoration areas will be minimized to transition and tie out areas of
the stream corridor.
The Project will provide increased floodplain access throughout the project area for all reaches and will
be monitored to demonstrate successful floodplain function. The stream channel design included
analysis of the hydrology, hydraulics, shear stress, sediment transport, and bankfull channel dimensions.
Draft Mitigation Plan
Slowplay Mitigation Project Page 20
WLS considered three methods (field indicators if present, published regional curve information, and
hydraulic modeling) for estimating a design bankfull discharge. The hydrology and hydraulics analysis
evaluated a range of lower flow discharges and flood frequency curves to help determine an appropriate
design discharge. The design discharge was used to select an appropriate channel geometry and help
monitor long-term project performance.
6.2 Design Criteria Selection
Selection of design criteria (Table 10) was based on a combination of approaches, including review of
reference data, flow regime equations, evaluation of monitoring results from successful past projects,
and best professional judgment. Evaluating data from reference reach surveys and monitoring results
from numerous Piedmont stream restoration projects provided pertinent background information to
determine the appropriate restoration potential and design parameters given the existing conditions,
current functions, and site constraints. The proposed stream design parameters also considered the
USACE Stream Mitigation Guidelines (USACE, 2003) and the Natural Channel Design Checklist (Harman,
2011) as described Section 6.4.

6.2.1 Stream Design Reach Summary
Restoration
S100-R1: The confined valley shape and steep stream profile dictated that S100-R1 be designed as a
Rosgen B-Type stream. The design incorporates a step-pool system with drops in profile elevation
spread out over a mixture of rock sills, log sills, stone riffles, cascading riffles, and existing bedrock slides.
Throughout the reach, the proposed stream channel cross-sectional area will be reduced compared to
the existing channel. Where appropriate, small, sloped flood benches will be constructed before the
proposed grading ties to the existing valley walls.
S100 begins at the jurisdictional origin of the existing stream, located between the downstream existing
farm pond and the breached upstream pond. A water quality feature will be constructed above the
proposed stream origin point to mitigate flashy runoff events and improve water quality before runoff
enters the stream. Upstream of the water quality feature, the breached dam associated with the upper
pond will be graded to a more natural valley shape and stabilized to promote sheet flow as runoff enters
the water quality feature. An existing crossing consisting of a metal drum culvert will be removed and
the crossing graded to match the surrounding valley landscape.
The stream alignment then moves into the existing farm pond with the proposed stream profile
positioned below the existing farm pond bottom. During the site survey, the pond bottom was probed
to determine the approximate elevation of mucky pond sediment as well as the elevation of more
consolidated soils underneath. The proposed stream profile cuts below the upper sediments into the
better, lower soils. Before construction, the pond will be breached and dewatered, and the existing
pond bottom will be allowed to dry as much as feasible. Unsuitable pond sediments will be removed
from the immediate vicinity of the stream corridor. Off-site rock will likely be necessary to construct the
in-stream structures through the pond bed. The existing crossing located at the top of the pond dam will
be reconfigured with a larger culvert and a floodplain relief culvert. The proposed crossing features a
lower crossing height and more stable embankments than the current dam. The proposed culvert will be
embedded a minimum of one foot with similar rocky material that is being used in the S100-R1 riffles
and will be capable of passing a 10% recurrence interval discharge event (10-year storm). When the
relief culvert is activated, the design will be capable of passing a 2% recurrence interval discharge event
(50-year storm). The entire crossing will be located within a 60-foot wide external break in the
conservation easement.
Below the existing pond, the valley narrows considerably, requiring much of the proposed stream
alignment to be located within the existing channel. Stream profile was raised in these areas to improve
stream access to the floodplain. In the few locations where the valley was less confined, off-line sections
of the stream were incorporated, and the old channel is backfilled to match the contours of the existing
valley. Several existing bedrock slides are tied into the proposed stream profiles and will be incorporated
into the stream design. Typically, the design improves the slides by excavating a pool immediately
before the bedrock and by setting a high sill downstream of the bedrock to form another large pool,
thus bounding the bedrock slide with stable constructed pools. Small gullies, located along the left valley
wall of the reach, will be stabilized with erosion control matting, seeding and live staking, and grading
where necessary. S100-R1 ends a few feet below an existing farm road crossing which will be removed,
and an appropriate floodplain graded in place.
Draft Mitigation Plan
Slowplay Mitigation Project Page 23
S100-R3: S100-R3 continues the B-stream design approach that was utilized for S100-R1. The reach
begins just above a large bedrock slide in the stream where a pool will be constructed before the stream
profile ties to the bedrock. A riffle and sill will be placed downstream of the bedrock to form a large pool
at the bottom of the bedrock. An existing farm road that parallels S100-R3 will be decommissioned and
revegetated. New floodplain and channel will be cut through the existing crossing, and the existing
perched culvert will be removed. The S100-R3 stream profile will then gradually descend into a short re-
alignment section where an existing, tortuous meander bend will be softened by moving the stream
alignment through the existing point bar and backfilling the old channel. Finally, the stream ties back to
the existing stream bed as it transitions to S100-R4.
S101: The existing ford crossing above S101 will be re-graded and enhanced with additional stone to
improve stability and access to the crossing. Just below the crossing, a water quality feature will be
constructed to slow flashy runoff events and to improve water quality before runoff enters the stream.
S101 begins at a large headcut in the existing channel. The banks and channel surrounding the headcut
will be graded to gentler slopes, stabilized, and revegetated. S101 channel design uses a similar B-type
approach to S100. The confined valley requires the proposed stream to be constructed over the existing
channel for much of the stream alignment. Elevation loss along the steep stream profile is distributed
over stable riffles and sills. Near the end of the stream, the existing eroding culvert crossing will be
removed and the crossing path reincorporated into the stream channel. The stream ends at an existing
bedrock slide sequence before entering the S100-R3 channel.
S102: S102 begins at a headcut in a small drainage within the S101 watershed. Above the stream origin,
a water quality feature will be constructed and the drainage stabilized. The channel design approach is
the same as S101 and incorporates an existing bedrock slide sequence into the in-stream structures. The
proposed channel will be constructed over the existing channel and tie out with sloped benches where
possible in the confined valley. The stream profile ties to the raised profile of S101 at the end of the
stream.
S103: Brush, plastic pipe, and other debris located near the origin of S103 will be removed from the
channel. Clean brush material will be incorporated into stream structures or as woody debris in the
floodplain. Other debris will be disposed of properly. The new channel will be defined and graded into
the existing debris-filled channel. Upstream, a water quality feature will be constructed to improve
water quality and stability within the drainage. The S103 channel design uses the same B-type approach
as the other steep streams in the project. The stream profile ties to an extended bedrock slide feature
where the surrounding banks will be graded back and stabilized. The stream ends at the confluence with
S100-R1.
S105: S105 begins as a groundwater seep located at the top of a small, steep valley. The seep area will
be excavated to remove excess sediment from cattle impacts. Steep banks surrounding the seep will be
graded back and stabilized. Construction traffic will be limited in the immediate vicinity of the
groundwater seep to protect it from excess disturbance. The proposed channel uses the same B-type
stream approach as the other steep streams in the project. The stream ends near the confluence with
S100-R1.
S200-R1: A water quality feature will be constructed in the drainage above the S200 stream origin. The
drainage will be stabilized including the banks and channel of the large headcut that is immediately
Draft Mitigation Plan
Slowplay Mitigation Project Page 24
upstream of the S200 origin. The first reach of the stream was designed as a B-type channel similar to
other steep streams on the project. Elevation is dropped over the stream profile on constructed riffles
and sills. The confined valley positions the proposed stream alignment over the existing channel for a
majority of the stream.
S200-R2: As S200 approaches the boundary of the project, the valley slope flattens, and the valley
becomes less confined. The design changes to a Cb-type approach, resulting in a more sinuous
alignment, fewer sills, and flatter, wider floodplains. A new reach was designated for the stream due to
the changing design parameters. The stream alignment is taken off-line in the wider valley to allow for a
more direct path to the stream outlet from the project. S200 leaves the project parcel and conservation
easement boundary at the same location where the existing stream leaves the property.
S201: S201 begins at a headcut in a small drainage within the S200 watershed. Above the stream origin,
a water quality feature will be constructed and the drainage stabilized. The channel design approach is
the same as S200 and incorporates an existing bedrock slide sequence into the in-stream structures. The
proposed channel will be constructed over the existing channel and tie out with sloped benches where
possible in the confined valley. The stream profile ties to the raised profile of S200 at the end of the
stream.
Enhancement Level II
S100-R2: Enhancement Level II activities along S100-R2 will include bank stabilization and
decommissioning of farm roads. Bank stabilization will target eroding banks along the reach which will
be graded back, seeded, stabilized with erosion control matting, and live staked. Road decommissioning
will consist of loosening the road soils to a minimum 12 inch depth and then revegetated according to
the revegetation plan. All disturbed areas of the conservation easement along this reach will be
stabilized and revegetated according to the revegetation plan.
S100-R4: S100-R4 work includes bank stabilization of small areas and the construction of a culvert
crossing before the stream’s confluence with S300. Eroding banks will be stabilized using the same
techniques as S100-R2. A point bar will also be graded into a sharp meander of the stream. Near the
downstream extents of the reach, a culvert crossing will be constructed within a 60-foot wide break in
the conservation easement. The stream alignment will deviate from the existing alignment
approximately 50 feet upstream of the crossing to improve the orientation of the culvert within the
stream corridor. Stream design approach is the same as S100-R3. The proposed culvert will be
embedded a minimum of one foot with similar rocky material that is being used in the S100-R1 riffles
and will be capable of passing a 10% recurrence interval discharge event (10-year storm). When the
relief culvert is activated, the design will be capable of passing a 4% recurrence interval discharge event
(25-year storm).
S104: Streambanks of S104 that are eroding or deemed unstable will have matting applied and live
staked. Due to the steep terrain in the area around S104, work in this area is expected to be handwork
only.
S300: Large woody debris and derelict culvert pipes will be removed from the S300 stream channel
throughout the reach. The woody debris will be reincorporated into stream structures, if suitable, or the
floodplain. Pipes and other debris will be removed from the conservation easement. Bank stabilization
Draft Mitigation Plan
Slowplay Mitigation Project Page 25
and the installation of toewood with geolift structures will occur along eroding banks. Log vanes and the
grading of point bars will be applied to the more extreme meanders in the stream to help turn water
around the bends. A gully located along the left bank of the stream will be stabilized using grading,
erosion control matting, seeding, and live stakes.
6.3 Flow Regime
Extensive research has demonstrated that a wide range of flows are essential to maintain stable and
high functioning habitat across ecological systems. The flow regime has been identified as the primary
factor in sustaining the ecological integrity of riparian systems (Poff et al. 1997) and is a key variable in
determining the abundance, distribution, and evolution of aquatic and riparian species (Schlosser 1985,
Resh et al. 1988, Power et al. 1995, Doyle et al. 2005). The ecological significance of variable stream
flows is more relative to flow duration, not necessarily just the flow recurrence interval. Seasonal flow
variations are impacted by natural and anthropogenic mechanisms (i.e. stressors) that correlate to
biological relationships and habitat response. Although dynamic, flow conditions can generally be
categorized as low flow, channel-forming flow, or flood flows, each with specific ecological significance
(Postel and Richter, 2003).
WLS recognizes the importance of seasonal flow variables and the ecological role they play in supporting
high functioning steams, both in smaller headwater systems (first order) and larger systems such as
S300. As such, flow monitoring will be conducted to demonstrate that the restored stream systems
exhibit seasonal base flow during a year with normal rainfall conditions. The stream surface flow
documentation methods are further described in Section 9. Table 11 summarizes the basic flow levels
and ecological roles the restoration design will provide after Project implementation.
Table 11. Flow Level and Ecological Role
Low Flow (Base Flow):
occurs most
frequently/seasonally
-Provide year-round habitat for aquatic organisms (drying/inundation pattern)
-Maintain suitable conditions for water temperature and dissolved oxygen
-Provide water source for riparian plants and animals
-Enable movement through stream corridor and refuge from predators
-Support hyporheic functions and aquatic organisms
Channel-forming Flow:
infrequent, flow duration of
a few days per year
-Shape and maintain physical stream channel form
-Create and maintain pools, in-stream and refuge habitat
-Redistribute and sort fine and coarse sediments
-Reduce encroachment of vegetation in channel and establishment of exotic
species
-Maintain water quality by flushing pollutants
-Maintain hyporheic connection by mobilizing bed and fine material
-Create in-channel bars for seed colonization of native riparian plants
Flood Flow: very infrequent,
flow duration of a few days
per decade or century
-Deposition of fine sediment and nutrients on floodplain
-Maintain diversity, function, and health of riparian floodplain vegetation
-Create streamside habitat, new channels, sloughs, and off-channel rearing
habitat through lateral channel migration and avulsion
-Recharge floodplain and storage processes
-Recruitment of native wood and organic material into channel

6.3.1 Regional Curve Comparison
Regional curves developed by Dunne and Leopold (1978) relate bankfull channel dimensions to drainage
area and are based on the channel forming discharge theory, which states that one unique flow can
yield the same channel morphology as the full range of flows. A primary purpose for developing regional
curves is to aid in identifying bankfull stage and dimension in un-gaged watersheds, as well as to help
predict the bankfull dimension and discharge for natural channel designs (Rosgen, 1994). Gage station
analyses throughout the United States have shown that the bankfull discharge has an average return
interval of 1.5 years or 66.7 percent annual exceedance probability on the maximum annual series
(Dunne and Leopold, 1978; Leopold, 1994).
Hydraulic geometry relationships are empirically derived and can be developed for a specific river or
extrapolated to a watershed in the same physiographic region with similar rainfall/runoff relationships
(FISRWG, 1998). Published and unpublished watershed specific bankfull regional curves are available for
a range of stream types and physiographic provinces. The NC Rural Piedmont Regional Curve (Harman et
al., 1999), unpublished NC Piedmont Regional Curve developed by the NRCS (NRCS, Walker, private
communication, 2015), and the NC Rural Mountain Curve (Harman et al. 2000) were used for
comparison when estimating bankfull discharge. The Regional Curve discharge equations and bankfull
hydraulic geometry equations are shown in Table 12.
Table 12. Regional Curve Equations
WLS has implemented numerous projects in drainages in the Piedmont hydrophysiographic province of
North Carolina, including projects in surrounding Piedmont counties, and has developed “mini-curves”
specific to these projects. The data set help reduce uncertainty by providing additional reference points
and supporting evidence for the selection of bankfull indicators. Channel slope, valley setting, channel

geometry, and sediment supply, as well as information from published United States Geological Survey
(USGS) regression analysis and Manning’s equations were all considered during examination of the field
data. The selected design bankfull discharges, cross-sectional areas, bankfull widths, and bankfull depths
were plotted on the Regional Curve comparison graphs found in Appendix C.
6.3.2 Channel Forming Discharge
A hydrologic analysis was completed to estimate and validate the design discharge and channel
geometry required to provide more frequent overbank flows and floodplain inundation. WLS used
multiple methods for evaluating the bankfull stage and dominant discharge for the Project reaches.
Cross-sections were identified and surveyed to represent reach-wide conditions. Additional bankfull
estimation methods, such as the commonly accepted Manning’s equation, were compared to help
interpret and adjust field observations to select the appropriate design criteria and justification for the
design approach.
The bankfull flows in gaged watersheds within the NC Rural Piedmont study documented return
intervals (RI) that ranges from 1.1 to 1.8, with a mean of 1.4 years (Harman et al, 1999). WLS also
compared the two-year flow frequency using the published USGS regression equations for rural streams
within the Piedmont hydrologic area of North Carolina (USGS, 2009, 2014). As expected, these values
fall slightly above the published bankfull discharge and were extrapolated to represent a wider range of
flows. WLS then compared lower flow frequencies in the 1.2-yr and 1.5-yr RI range versus existing
conditions survey data and LiDAR Digital Elevation Model (DEM).
It should be noted that this best fit approach does not always match the dataset, since it falls at the low
end of the curve. Therefore, caution should be used when comparing these lower RIs with additional
data sets. Using the rationale described above, the bankfull discharge analyses compared rural
Piedmont and Mountain regional curves, Manning’s equation discharges calculated from the
representative cross-section geometry for existing reaches, and published USGS regional regression
equations.

After considering these estimation methods and results (geometry measurements, regional curves, flow
frequency, and USGS regional regression equations), WLS estimated the design discharge using values
between the unpublished NC Rural Piedmont Regional Curve and the published NC Rural Mountain
regional curve to select the appropriate design dimensions and flows rates that best correspond to the
design channel that will convey the 1.2-yr to 1.5-yr RI. The design discharge analysis summary is
provided in Appendix C.
6.3.3 Channel Stability and Sediment Transport Analysis
WLS investigated potential sediment sources from the upstream watershed and performed pebble
counts in several reaches to characterize substrate material. The pebble count results indicate that the
dominant bed material in the stream reaches is small cobbles under current conditions, with bedrock
and small boulders playing an important role in maintaining grade within the system. The results of the
counts were used to classify the streams and complete critical shear stress calculations required for
designing slopes/depths and predicting channel stability. Despite cattle access and eroding banks
contributing fine sediment to the system, the competence and capacity of the streams is a low concern
due to the steep stream slopes at the site and because fine sediment supply is expected to be curtailed
via the exclusion of cattle and stabilization of streambanks. Instead, emphasis was placed on
determining stable substrate size for the designed streams to reduce the potential for channel
degradation in the system. The sediment transport capacity was analyzed to help predict stable channel
design conditions and bankfull discharges for the Project reaches. Sediment transport analysis data

As a design consideration, portions of the bed material will contain particle sizes greater than the
moveable particle sizes as predicted by the Rosgen Curve above. In general, sections with steeper slopes
(>4 percent) will be addressed by installing a combination of grade control structures such as wood/rock
riffles, angled log sills, and boulder sills. Incorporating these structures will prevent further channel
degradation and embeddedness, promote natural scour and sediment storage, and increase bed/bank
stability since shear stress and sediment entrainment are directly affected by factors such flow energy
distribution and channel resistance.

6.4 Reference Sites
6.4.1 Reference Streams
The morphologic data obtained from reference reach surveys can be a valuable tool for comparison and
used as a template for analog design of a stable stream in a similar valley type, drainage area, valley
slope, and bed material. To obtain morphological relationships in a stable stream system, dimensionless
ratios were compared from the composite reference reach data shown in Table 15. WLS selected
reference reaches in the NC Piedmont and compared them with composite reference reaches within the
same climatic, hydrophysiographic, and ecoregion as that for the Project site. These ratios were
considered in the stream design to ‘mimic’ the natural, stable form of the target channel type.
While reference reach data can be a useful aid in analog design, they are not always appropriate and can
have limitations in ungaged or smaller stream systems (Hey, 2006). The channel morphology for
reference reach quality streams is controlled by valley slope, bed material, drainage areas, land use
(stressors), geology, and large trees and/or other deep-rooted vegetation.

Note 1: Reference reach data from Shoals Community Park (SCP) was used to compare with S200-R2. Reference
reach data from Upper Rocky – Reach 4 (UR-R4) and Grassy Creek Tributary – Reach 6A (GCT-R6A) were used to
compare with the steep “B” type streams at the Project site. This data was collected from previous successful
restoration projects.
Note 2: Composite reference reach values and ratios were developed from multiple stable stream restoration
projects monitored in the NC Piedmont as illustrated in the Natural Channel Design Checklist (Harman, 2011).
Shoals Community Park (SCP): Shoals Community Park is a small first order rural Piedmont stream
(Rosgen C4b stream type) located in Surry County, NC that was restored in 2008. WLS visited the site
and conducted a geomorphic survey in Spring 2018 to confirm that the stream was stable and reference
Draft Mitigation Plan
Slowplay Mitigation Project Page 31
quality. The stream flows through the east side of the park and originates just west of Shoals Road. The
riparian corridor is vegetated, and the stream has conservative meander geometry (k=1.16) as it flows
across the natural valley bottom. Bedform diversity consists of rock riffles, small boulder steps, and
angled log drops.
Upper Rocky – Reach 4 Upstream (UR-R4): Upper Rocky Reach 4 is a small Piedmont, headwater stream
(Rosgen B6c stream type) located in Mecklenburg County, NC. The upstream portion of this reach was
noted as stable with good stream bedform in the existing step-pool channel. Access to a large floodplain
was available for most of the reach length. The stream is similar in drainage area and valley location to
several of the Project streams. Construction was completed in 2022, and stability of the stream has been
monitored in the ensuing years.
Grassy Creek Tributary – Reach 6A (GCT-R6A): Grassy Creek Tributary Reach 6A is a restored stream
located in Surry County, NC within the Upper Yadkin River Basin (HUC 03040101). The stream was
restored as a B4a type stream with a step-pool design. Bank grading and floodplain were limited in some
locations along the reach due to the steep and confined nature of the valley. Restoration of the stream
was completed in 2020, and the reach has been monitored for stability in the ensuing years.
6.5 Water Quality Treatment Features
Water quality treatment features (WQTF) in the form of small depressions or basins are designed to
treat runoff from the surrounding agricultural areas. The WQTF are proposed along upper S100, S101,
S102, S103, S200, and S201. The WQTF function most like a stormwater wetland to temporarily store
surface runoff in shallow pools that support emergent and native riparian vegetation. The features
should increase infiltration and groundwater recharge, diffuse flow energies, trap sediment inputs from
upland areas, and allow nutrient uptake within the project area.
The WQTF will be installed along non-jurisdictional areas where ephemeral drainages intersect with the
proposed restored stream corridor. The areas will be improved and stabilized by grading flatter side
slopes (>3H:1V) and planting appropriate vegetation. Over time, as vegetation becomes established, the
areas will function as shallow wetland complexes or depressions. The outlet channels will be
constructed with suitable material and stabilized with permanent vegetation and stone that will deliver
reduced runoff and prevent headcut migration and/or erosion into the newly constructed stream
channels. This strategy will allow the features to function properly with minimal risk and without long-
term maintenance requirements. See Appendix A design plan sheets for details and feature locations.
6.6 Revegetation Plan
Riparian buffers will be established a minimum of 50 feet from the top of the streambanks along each of
the Project reaches, as well as permanently protecting those buffers with a conservation easement.
Proposed plantings will be conducted using native tree species predominantly consisting of bare root
vegetation planted at a total target density of 680 stems per acre. Additionally, live staking will establish
woody stems along stream reaches and wet-weather conveyances. The proposed plant selection will
help to establish canopy cover and soil stability based on an appropriate reference community, Mesic
Mixed Hardwood Forest (Piedmont Subtype) (Schafale, 2012). Species proposed for revegetation
planting are presented in Table 16.

Note: WLS will plant minimum eight (8) bare root species from the list with no one species exceeding 15%
composition; green ash will not exceed 4%. A minimum of three (3) live stake species will be planted with no one
species exceeding 60% composition. Final planting decisions will be made at construction based on availability.
6.6.1 Planting Materials and Methods
Planting will be conducted during the dormant season, with all trees installed between mid-November
and March 15th. The final planting zone limits may be modified based on these observations and
comparisons, and the final selection of the location of the planted species will be matched according to
the species wetness tolerance and the anticipated wetness of the planting area.
Live Staking and Live Branch Cuttings: Where live staking is proposed on streambanks, live stakes will
typically be installed at a minimum of 40 stakes per 1,000 square feet, and the stakes will be spaced
approximately three feet apart in meander bends and six feet apart in the riffle sections, using a
triangular spacing pattern along the streambanks, between the toe of the streambank and bankfull
elevation. When bioengineering is proposed, live branch cutting bundles will be installed at five linear
feet per bundle approximately two to three branches thick. Table 16 includes the proposed live stake
species and quantities.
Permanent Seeding: Temporary and permanent seeding will be conducted simultaneously at all
disturbed areas of the Project site during construction and will conducted with mechanical broadcast
spreaders. Table 17 lists the proposed species, mixtures, and application rates for permanent seeding.
The vegetation species proposed for temporary seeding germinate quickly to swiftly establish vegetative
ground cover and thus, short term stability. The permanent seed mixture proposed is suitable for both
the mixed-mesic and bottomland hardwood forest planting zones. This mix will be appropriate for
streambank, floodplain, adjacent riparian wetland areas, and the upland transitional areas in the
Draft Mitigation Plan
Slowplay Mitigation Project Page 33
riparian buffer. Beyond the riparian buffer areas, temporary and permanent seeding will also be
conducted at all other disturbed areas of the Project site that are susceptible to erosion. If temporary
seeding is applied from November through April, rye grain will be used and applied at a rate of 130
pounds per acre. If applied from May through October, temporary seeding will consist of browntop
millet, applied at a rate of 40 pounds per acre.

Note: Final species selection may change due to refinement or availability at the time of planting. Species
substitutions will be coordinated between WLS and planting contractor prior to the procurement of seeding stock.
Invasive Species: There is not a significant presence of invasive species vegetation in the project area.
There are sparse occurrences (totaling less than five percent) of multiflora rose located in existing
riparian buffers. Additional wooded areas within the project area contain individual or small clumps of
Chinese privet totaling less than five percent of overall vegetation. A small cluster of kudzu is present
outside of the proposed easement located above S201. During the Project implementation, invasive
species exotic vegetation will be treated both to control its presence and reduce its spread within the
conservation easement areas.
6.7 Site Construction Methods
6.7.1 Site Grading and Construction Elements
Much of the grading across the Project site will be conducted within the existing riparian corridor. The
restored streams will be constructed within the existing natural valleys. Suitable fill material will be
generated from new channel excavation and adjacent upland areas and hauled to ditch fill/plugs or
stockpile locations, as necessary. Portions of the existing, unstable channels will be partially to
completely filled in along their length using compactable material excavated from construction of the
restored channels.
Floodplain grading activities will focus on providing flood relief during larger flow events. Floodplain
grading extents are balanced with avoiding destabilizing steep valley walls and saving existing trees and
vegetated areas along the Project streams. Additional work in the riparian buffer will include the
construction of water quality features, the decommissioning of existing dirt farm roads, and the
Draft Mitigation Plan
Slowplay Mitigation Project Page 34
stabilization of existing drainages and gullies. Any excess material not used for ditch plugging or suitable
as a soil base for vegetation will be spread across upland areas outside of the easement boundary and
jurisdictional WOTUS.
6.7.2 Stream, and Floodplain Improvement Features
Stream improvement features such as in-stream structures and bioengineering techniques are proposed
for grade control, streambank protection, and improving bedform diversity and habitat. All in-stream
structures will be constructed from materials naturally found in the region such as hardwood trees,
trunks/logs, brush/branches, and gravel stone materials. Whenever possible, existing substrate material
in the abandoned stream channels will be harvested and utilized for the new channel locations.
WLS will also incorporate bioengineering practices, when appropriate, that use biodegradable materials
and fabrics, uncompacted soils, live plant cuttings, and native species vegetation to stabilize
streambanks. Bioengineering treatments will provide initial bank stability that allow for the quick
establishment of deep-rooted vegetation along the newly restored streambanks. Additionally, floodplain
improvement features such as large woody debris (LWD) will be installed. This will mimic features like
tree throws, snags, stumps, etc. that are commonly found in natural riparian systems. These floodplain
improvement features will be added to provide habitat and serve as water storage and sediment sinks
throughout the corridor to improve riparian functions (Dooley, 2003).
6.7.3 Construction Feasibility
WLS has field verified that the Project site has adequate, viable construction access, staging, and
stockpile areas. Physical constraints or barriers, such as stream crossings, account for only a small
percentage of the proposed total stream reach length within the Project boundary. Existing Project site
access points and features will be used for future access after the completion of construction.
6.7.4 Future Project Risks and Uncertainties
Listed below are identified project risks and uncertainties that have been evaluated in the development
of design plans for the site, along with methods that have been/will be used to address these concerns.
Land Use Development: There is minimal risk that changes in land use upstream in the Project
watershed would alter the hydrology or sediment supply enough to impair the project streams after
construction. The Project area has seen little to no development in recent years, and it is unlikely
development will the threaten the site.
o Methods to Address: Restoration and reforestation of the site streams will reduce the likelihood
of future degradation from watershed changes, as erosive flood flows will spread over a wider
reconnected floodplain.
Easement Encroachment: There is potential for landowner or cattle encroachment into the permanent
conservation easement.
o Methods to Address: WLS has had considerable discussions with the landowner regarding the
Project requirements and limitations of easement access and is confident that the landowners
fully understand and will maintain the easement protections. The easement boundaries will be
Draft Mitigation Plan
Slowplay Mitigation Project Page 35
clearly marked per requirements. The easement will be fenced in all areas where cattle may
have access. Any encroachments that do occur will be addressed by WLS or the long-term
steward to remedy any damage and provide any other corrections required by the IRT.
Drought and Floods: There is potential for extreme climatic conditions during the monitoring period of
the Project.
o Methods to Address: WLS will apply adaptive management techniques as necessary to meet the
site performance criteria. Such adaptive management may include replanting, channel damage
repair, irrigation, or other methods. If adaptive management activities are significant, additional
monitoring may be required by the IRT.
Beavers: While there was no evidence of beaver activity during recent assessments, there is potential
for beavers to affect the site during the monitoring period of the Project.
o Methods to Address: WLS will take steps to trap and remove beaver if they threaten Project
success during the monitoring period.
7 Maintenance Plan
The Project will be monitored on a regular basis and a physical inspection of the Project will take place
at least twice a year throughout the post-construction monitoring period until performance standards
are met. These inspections may identify Project components and features that require routine
maintenance. Routine maintenance is anticipated in the years following Project construction and may
include the following components as described in Table 18.
Draft Mitigation Plan
Slowplay Mitigation Project Page 36
Table 18. Routine Maintenance Components
Feature Maintenance Activity Through Close-out
Stream Routine channel maintenance and repair activities may include modifying in-stream structures to
prevent piping, securing loose coir matting, and supplemental installation of live stakes and other
target vegetation along the Project reaches. Areas of concentrated stormwater and floodplain flows
that intercept the channel may also require maintenance.
Vegetation Vegetation will be maintained to ensure the health and vigor of the targeted plant community. Routine
vegetation maintenance and repair activities may include supplemental planting, pruning, and
fertilizing. Exotic invasive plant species will be treated by mechanical and/or chemical methods. Any
invasive plant species control requiring herbicide application will be performed in accordance with
North Carolina Department of Agriculture (NCDA) rules and regulations.
Project Site
Boundary
Project boundaries will be demarcated in the field to ensure clear distinction between the Project site
and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, or other means
as allowed by Project conditions and/or conservation easement. Boundary markers disturbed,
damaged, or destroyed will be repaired and/or replaced on an as needed basis.
Beaver
Management
Routine maintenance and repair activities caused by beaver activity may include supplemental
planting, pruning, and dewatering/dam removal. Beaver management will be implemented using
accepted trapping and removal methods only within the recorded Conservation Easement.
Stream
Crossing
The stream crossing(s) within the Project may be maintained only as allowed by the recorded
Conservation Easement, deed restrictions, rights of way, or corridor agreements. Stream crossings will
be excluded from the easement area and maintained by the landowner.
8 Performance Standards
The success criteria for the Project will follow the approved performance standards and monitoring
protocols presented in this mitigation plan which have been developed in compliance with the USACE
October 2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008
Compensatory Mitigation Final Rule. Monitoring activities will be conducted for a period of seven years
with the final duration dependent upon performance trends toward achieving the Project goals and
objectives. Specific success criteria components and evaluation methods are described below.
8.1 Streams
Stream Hydrology: Four bankfull flow events must be documented within the seven-year monitoring
period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will
continue until four bankfull events have been documented in separate years.
Stream Profiles, Vertical Stability, and Floodplain Access: Stream profiles, as a measure of vertical
stability and floodplain access will be evaluated by measuring Bank Height Ratios (BHR) and
Entrenchment Ratios (ER). In addition, bedforms and pool to pool spacing should be consistent for
channels of the design stream type(s). The BHRs shall be ≤1.2 and the ERs ≥2.2 along the restored Project
stream reaches. This standard only applies to restored reaches of the channel where BHRs and ERs are
corrected through design and construction.
Stream Horizontal Stability: Cross-sections will be used to evaluate horizontal stream stability. There
should be minimal changes in cross-section geometry during the monitoring period. If measurable
Draft Mitigation Plan
Slowplay Mitigation Project Page 37
changes do occur, they should be evaluated to determine if the changes represent a movement toward a
more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g.,
settling, vegetation establishment, deposition along the streambanks, decrease in width/depth ratio).
Cross-sections shall be classified using the Rosgen Stream Classification method, and all monitored cross-
sections should fall within the quantitative parameters defined for channels of the design stream type.
Streambed Material Condition and Stability: After construction, there should be minimal change in the
particle size distribution of the streambed materials, over time, given the current watershed conditions
and anticipated upstream sediment supply. Since the stream substrate and instream structures have
been sized for stability and upstream sediment supply is expected to be greatly reduced, significant
changes in particle size distribution and excess channel aggradation are not expected.
Jurisdictional Stream Flow: The restored stream systems must be classified as at least intermittent, and
intermittent streams must exhibit 30 days of continuous flow for some portion of the year during a year
with normal rainfall conditions. A post restoration flow gauge will be installed on S100-R1, S103 and
S105.
Photo Documentation: Photographs should illustrate the Project’s vegetation and morphological
stability on an annual basis. Permanent photo stations will be set up at all cross-sections and above and
below the stream crossings. Cross-section photos should demonstrate no excessive erosion or
degradation of the banks. Longitudinal photos should indicate the absence of persistent mid-channel
bars or vertical incision. Grade control structures should remain stable.
8.2 Vegetation
Vegetative restoration success for the Project during the intermediate monitoring years will be based on
the survival of at least 320, three-year-old planted stems per acre at the end of Year 3 of the monitoring
period; and at least 260, five-year-old planted stems per acre that must average seven feet in height at
the end of Year 5 of the monitoring period. The final vegetative restoration success criteria will be
achieving a density of no less than 210, seven-year-old planted stems per acre that must average 10 feet
in height in Year 7 of monitoring.
8.3 Invasive Species
WLS will treat invasive species vegetation within the Project area and provide remedial action on a case-
by-case basis. Common invasive species vegetation, such as Chinese privet, kudzu and multiflora rose
will be removed to allow native plants to become established within the conservation easement.
Invasive species vegetation will be treated by approved mechanical and/or chemical methods. Any
control methods requiring herbicide application will be performed in accordance with NCDA rules and
regulations. If necessary, these removal treatments (i.e., cutting and/or spraying) will continue until the
corrective actions demonstrate that the site is trending towards or meeting the standard monitoring
requirement.
9 Monitoring Plan
In accordance with the approved mitigation plan, the baseline monitoring document and as-built report
documenting the mitigation activities will be developed within 60 days of the completion of planting and
Draft Mitigation Plan
Slowplay Mitigation Project Page 38
monitoring device installation at the restored Project. In addition, a period of at least six months will
separate the as-built baseline measurements and the first-year monitoring measurements. The baseline
monitoring document and as-built monitoring report will include all information required by the USACE
Stream Mitigation Guidelines, issued in April 2003 and USACE Guidance for Compensatory Stream and
Wetland Mitigation Conducted for Wilmington District dated October 2016.
WLS will conduct mitigation performance monitoring based on these methods and will submit annual
monitoring reports to IRT by December 31st of each monitoring year during which required monitoring is
conducted. Project success criteria must be met by the final monitoring year prior to Project closeout, or
monitoring will continue until unmet criteria are successfully met. The following subsections summarize
the monitoring methods and linkage between the goals, parameters, and expected functional lift
outcomes. Figure 10 illustrates the post-construction monitoring feature types and location.
9.1 Stream Monitoring
Hydrologic monitoring will be conducted for all the Project stream reaches. For reaches that involve a
combination of Restoration (Rosgen Priority Level I and II) approaches, geomorphic monitoring methods
will be employed to evaluate the effectiveness of the restoration practices. Visual monitoring will be
conducted along these reaches as described herein. For the Project reaches involving an Enhancement
Level II approach, monitoring efforts will focus primarily on geomorphic monitoring, visual inspections,
photo documentation, and vegetation assessments, each as described herein. In areas where bank
stabilization occurs, geomorphic monitoring methods will be used. The monitoring of these Project
reaches will utilize the methods described under visual monitoring.
9.1.1 Hydrologic Monitoring
The occurrence of four required bankfull events within the monitoring period, along with floodplain
access by flood flows, will be documented using pressure transducers and/or photography. The pressure
transducers will be installed in pools and correlating sensor depth to top of bank elevation. Recorded
water depth above the top of bank elevation will document a bankfull event. Corresponding
photographs will be used to document the occurrence of debris lines and sediment deposition on the
floodplain during monitoring site visits. This hydrologic monitoring will help establish that the
restoration objectives of restoring floodplain functions and promoting more natural flood processes are
being met.
9.1.2 Geomorphic Monitoring
Pattern: A planimetric survey will be conducted for the entire length of restored channel immediately
after construction to document as-built baseline conditions (Monitoring Year 0). The survey will be tied to
a permanent benchmark and measurements will include thalweg, bankfull, and top of banks. The plan
view measurements such as sinuosity, radius of curvature, and meander width ratio will be taken on
newly constructed meanders during baseline documentation (Monitoring Year 0) only. These
measurements will demonstrate that the restored stream channel pattern provides more stable planform
and associated features than the old channel, which provide improved aquatic habitat and geomorphic
function, as per the restoration objectives.
Draft Mitigation Plan
Slowplay Mitigation Project Page 39
Dimension: Twenty-six (26) permanent cross-sections will be installed and surveyed at an approximate
rate of one cross-section per 20 bankfull widths or an average distance interval (not to exceed 500 LF) of
restored stream, with approximately 50 percent cross-sections located at riffles, and 50 percent located
at pools. Each cross-section will be monumented on both streambanks to establish the exact transect
used and to facilitate repetition each year and easy comparison of year-to-year data. The cross-section
surveys will occur in years 0 (as-built), 1, 2, 3, 5, and 7, and will include measurements of bankfull cross-
sectional area (Abkf) at low bank height, Bank Height Ratio (BHR) and Entrenchment Ratio (ER). The
monitoring survey will include points measured at all breaks in slope, including top of streambanks,
bankfull, inner berm, edge of water, and thalweg, if the features are present.
There should be minimal change in as-built cross-sections. Stable cross-sections will establish that the
restoration goal of creating geomorphically stable stream conditions has been met. If changes do take
place, they will be documented in the survey data and evaluated to determine if they represent a
movement toward a more unstable condition (e.g., down-cutting or erosion) or a movement toward
increased stability (e.g., settling, vegetative changes, deposition along the streambanks, or decrease in
width-to-depth ratio). Using the Rosgen Stream Classification System, all monitored cross-sections should
fall within the quantitative parameters defined for channels of the design stream type. Given the smaller
channel sizes and meander geometry of the proposed steams, bank pin arrays will not be installed unless
monitoring results indicate active lateral erosion at cross-sections occurring in meander bends or an
increase of greater than 15 percent in cross-sectional area, or when visual monitoring indicates potential
bank instability.
Reference photo transects will be taken at each permanent cross-section. Lateral photos should not
indicate excessive erosion or continuing degradation of the streambanks. Photographs will be taken of
both streambanks at each cross-section. A survey tape stretched between the permanent cross-section
monuments/pins will be centered in each of the streambank photographs. Photographers should attempt
to consistently maintain the same area in each photo over time.
Profile: A longitudinal profile will be surveyed for the entire length of restored channel immediately after
construction (Monitoring Year 0) to document as-built baseline conditions. The survey will be tied to a
permanent benchmark and measurements will include thalweg, water surface, bankfull, and top of low
bank. Each of these measurements will be taken at the head of each feature (e.g., riffle, pool) and at the
maximum pool depth. The longitudinal profile should show that the bedform features installed are
consistent with intended design stream type. The longitudinal profiles will not be taken during
subsequent monitoring years unless vertical channel instability has been documented or remedial
actions/repairs are deemed necessary. Bank height ratios will be measured along the restored reaches
using the results of the longitudinal profile.
9.1.3 Flow Duration Monitoring
Jurisdictional Stream Flow Documentation: Monitoring of stream flow will be conducted to demonstrate
that the restored stream systems classified as intermittent exhibit surface flow for a minimum of 30
consecutive days throughout some portion of the year during a year with normal rainfall conditions. To
determine if rainfall amounts are normal for the given year, precipitation amounts using tallied data
obtained from the Taylorsville Station (GHCN:USC00318519), which is approximately 4.8 miles north of
the Project, will be used, and a rain gauge will be installed on site. If a normal year of precipitation does
Draft Mitigation Plan
Slowplay Mitigation Project Page 40
not occur during the first seven years of monitoring, monitoring of flow conditions at the Project site will
continue until it documents that the intermittent streams have been flowing during the appropriate
times of the year. A flow gauge will be installed on S100-R1, S103 and S105. The proposed monitoring of
restored intermittent reaches will include the installation of flow devices (continuous-read pressure
transducers) installed in pools and correlating sensor depth to the downstream top of riffle elevation. If
the pool water depth is at or above the top of riffle elevation, then the channel will be assumed to have
surface flow. The devices will be installed in the upper one-third portion of the reach. In addition,
photographic documentation using a continuous series of remote photos over time may be used to
subjectively evaluate and document channel flow conditions throughout the year. More specifically, the
longitudinal photos should indicate the presence of flow within the channel to illustrate water levels
within the pools and riffles. The photographs will be taken from a height of approximately five feet to
ensure that the same locations (and view directions) at the Project site are documented in each
monitoring period and will be shown on a plan view map. The devices will be inspected on a quarterly
basis to document surface hydrology and provide a basis for evaluating flow response to rainfall events
and surface runoff throughout the monitoring period.
9.2 Vegetation Monitoring
Vegetation-monitoring quadrants or plots will be installed and monitored across the Project in
accordance with the CVS-EEP Level I & II Monitoring Protocol (CVS, 2008). The vegetation monitoring
plots shall comprise approximately two percent of the proposed planted portion (14.47 acres) of the
Project site with approximately six (6) fixed plots established randomly within the planted riparian
buffer areas and three (3) random transect plots. The sampling may employ annually located quasi-
random plot locations, which may vary upon approval from IRT. Any random plots should comprise no
more than 50 percent of the total required plots, and the location (GPS coordinates and orientation) will
be identified in the monitoring reports. The size and location of fixed plots will be 100 square meters
(i.e., 10m X 10m or 5m X 20m) for planted stems and may be adjusted based on site conditions after
construction activities have been completed. No monitoring quadrants will be established within
undisturbed wooded preservation or enhancement areas, however visual observations will be
documented in the annual monitoring reports to describe any changes to the existing vegetation
community.
Vegetation monitoring will occur in the fall each required monitoring year, prior to the loss of leaves.
Mortality will be determined from the difference between the previous year's living, planted seedlings
and the current year's living, planted seedlings. Data will be collected at each individual quadrant and
will include specific data for monitored stems on height, species, date planted, and grid location, as well
as a collective determination of the survival density within that quadrant. Volunteer species will be
noted and if they are on the approved planting list and meet success criteria standards, they will be
counted towards success criteria. Other species not included on the list may be considered by the IRT on
a case-by-case basis.
The presence of invasive species vegetation within the monitoring quadrants will also be noted, as will
any wildlife effects. At the end of the first full growing season (from baseline/year 0) or after 180 days,
species composition, stem density and survival will be evaluated. For each subsequent year, vegetation
plots shall be monitored for seven years in years 1, 2, 3, 5 and 7, and visual monitoring in years 4 and 6,
or until the final success criteria are achieved.

9.3 Visual Assessment Monitoring
WLS will conduct visual assessments in support of mitigation performance monitoring. Visual
assessments of all stream reaches will be conducted at least twice per monitoring year with a minimum
of five months in between each site visit throughout the monitoring period. Photographs will be used to
visually document system performance and any areas of concern related to streambank and bed stability,
condition of in-stream structures, channel migration, active headcuts, live stake mortality, impacts from
invasive plant species or animal browsing, easement boundary encroachments, cattle exclusion fence
damage, and the general condition of pools and riffles. The monitoring activities will document and
quantify the visual assessment throughout the monitoring period.
A series of photographs over time will be compared to subjectively evaluate channel aggradation (bar
formations) or degradation, streambank erosion, successful maturation of riparian vegetation, and
effectiveness of sedimentation and erosion control measures. More specifically, the longitudinal profile
photos should indicate the absence of developing bars within the channel or excessive increase in
channel depth, while lateral photos should not indicate excessive erosion or continuing degradation of
the banks. The photographs will be taken from a height of approximately five feet to ensure that the
same locations (and view directions) at the Project site are documented in each monitoring period and
will be shown on a plan view map. The results of the visual monitoring assessments will be used to
support the development of the annual monitoring document that provides the visual assessment
metrics.

10 Long-Term Management Plan
The Project will be protected in perpetuity by a recorded conservation easement. The conservation
easement will allow for annual monitoring and maintenance of the Project during the monitoring phase.
Upon final site approval and project closeout, the Project stewardship will be transferred to an approved
long-term stewardship program. WLS has partnered with Unique Places To Save (UP2S) as the long-term
steward for the Project site (See Appendix D for conservation easement template and engagement
letter).

Draft Mitigation Plan
Slowplay Mitigation Project Page 43
This party shall serve as conservation easement holder and long-term steward for the property and will
conduct periodic inspection of the Project to ensure that restrictions required in the conservation
easement are upheld. Any endowment funds for the conservation easement and deed restrictions shall
be negotiated prior to transfer to the responsible party. Funding will be supplied by the responsible
party on a yearly basis until such time and endowments are established. The use of funds from the
Endowment Account is governed by NC General Statue GS 113A-232(d) (3). Payments and interest
gained by the endowment fund may be used only for stewardship, monitoring, stewardship
administration, and land transaction costs, if applicable. The management activities will be conducted in
accordance with the terms and conditions of the approved MBI as agreed to by WLS, USACE, and the
IRT.
11 Adaptive Management Plan
The Sponsor will conduct post-construction monitoring activities and routine maintenance as needed for
the duration of the monitoring period. The Sponsor will notify the USACE immediately if monitoring
results or visual observations demonstrate that performance standards cannot be achieved. In the event
the Project site or a specific component of the Project site fails to achieve the performance standards as
specified in the mitigation plan, the sponsor shall notify the IRT and develop a corrective action plan and
facilitate remedial actions. The Sponsor is responsible for providing any necessary permits to implement
the corrective action plan that describes the extent and nature of the work to be performed. If the
USACE determines that the Project 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 holding credit sales, utilizing financial assurances, and/or terminating the instrument.
The site will be monitored on a regular basis and a physical inspection of the site will take place at least
once a year throughout the post-construction monitoring period until performance standards are met.
These site inspections may identify site components and features that require routine maintenance.
Routine maintenance should be expected most often in the first two years following site construction.
12 Financial Assurances
CONFIDENTIAL
The Sponsor will provide financial assurances in the form of casualty insurance or a performance bond
that is acceptable to the USACE and sufficient to assure successful completion of all mitigation bank
activities, reporting and monitoring, and any remedial work required pursuant to the approved
Mitigation Plan and/or UMBI. The insurance policy or performance bond will be submitted for review
and approval by the USACE. The financial assurance will cover the cost estimates for providing the
mitigation bank activities such as site mobilization and construction, annual monitoring, and reporting as
outlined in Table 20 and broken out by annual cost below. There will be a financial assurance for the
construction phase in the amount of $1,292,380, and that financial assurance will be retired following
completion of construction and planting. Then, a monitoring financial assurance in the amount of
$242,042 will be provided to assure completion of seven years of monitoring and reporting, and any
remedial work required during the monitoring period.

The monitoring financial assurance will be reduced following approval of each annual monitoring report
as provided in the financial assurance policy. However, monitoring years 1 through 3 will keep the full
contingency amount of $77,542 and the contingency will be reduced starting in monitoring year 4. The
monitoring financial assurance will be retired in total following official notice of site close-out from the
IRT. Financial assurances shall be payable to a standby trust or other designee at the direction of the
oblige or lender. Financial assurances structured to provide funds to the USACE in the event of default
by the Bank Sponsor are not acceptable. The USACE shall receive notification at least 120 days in
advance of any termination or revocation. In the event of Sponsor default, UP2S has agreed to receive
the endowment funds and will ensure the mitigation work is successfully completed.

SUBSTRATE RESTORATION NOTES:
THE FOLLOWING SPECIFICATION IS DESIGNED TO REPLACE AND RESTORE COARSE (GRAVEL, COBBLE, BOULDER AND BEDROCK) SUBSTRATE TO THE STREAM CHANNEL IN CASES
WHERE COARSE SUBSTRATES ARE ABSENT FOLLOWING CHANNEL EXCAVATION. THE PURPOSE OF THIS RESTORATION MEASURE IS TO PROVIDE NATURAL SUBSTRATE AND EROSION
AND SCOUR PROTECTION IN THE CHANNEL.
1. SUBSTRATES COMPRISED PREDOMINANTLY OF GRAVEL (0.08-2.5 INCHES), COBBLE (2.5-10.1 INCHES) AND/OR BOULDER (10.1-80 INCHES), ALSO REFERRED TO IN THIS
SPECIFICATION AS COARSE SUBSTRATE OR ALLUVIUM, THAT ARE REMOVED FROM THE STREAM DURING CHANNEL EXCAVATION WILL BE TEMPORARILY STOCKPILED IN A
NON-WETLAND/AQUATIC SITE FOR POSSIBLE REPLACEMENT IN THE CHANNEL.
2. IMMEDIATELY FOLLOWING CHANNEL EXCAVATION, PERFORM AND RECORD THE RESULTS OF A PEBBLE COUNT (HARRELSON ET AL. 1994) IN THE EXCAVATED CHANNEL TO
DETERMINE THE PERCENT COMPOSITION OF SILT/CLAY, SAND, GRAVEL, COBBLE, BOULDER, AND BEDROCK SIZE CLASSES.
3. IF THE IN-PLACE STREAM SUBSTRATE IS COMPRISED OF GREATER THAN 70% GRAVEL, COBBLE, BOULDER, AND/OR BEDROCK, THE STREAM SUBSTRATE WILL BE DEEMED
ACCEPTABLE AS IS AND SUBSTRATE REPLACEMENT WILL NOT BE PERFORMED.
4. IF THE IN-PLACE STREAM SUBSTRATE IS COMPRISED OF LESS THAN 70% GRAVEL, COBBLE, BOULDER, AND/OR BEDROCK, THE CHANNEL WILL BE OVER-EXCAVATED TO A DEPTH
OF 6 TO 8 INCHES AND BACKFILLED WITH COARSE SUBSTRATE TO MEET THE >70% SPECIFICATION, AS VERIFIED BY A PEBBLE COUNT.
5. COARSE ALLUVIUM EXCAVATED FROM THE CHANNEL AND TEMPORARILY STOCKPILED IS THE PREFERRED MATERIAL TO USE FOR SUBSTRATE REPLACEMENT.
6. IF THE QUANTITY OF EXCAVATED COARSE ALLUVIUM IS INSUFFICIENT OR CONTAINS TOO HIGH A PERCENTAGE OF FINES (SAND, SILT, AND CLAY), THEN THE FOLLOWING MIXTURE
OF MATERIALS CAN BE USED AS SUBSTRATE:
A. CLEAN, NON-ACID FORMING ROUNDED NATURAL ROCK AND STONE, SUCH AS RIVER GRAVEL, LIMESTONE OR SANDSTONE;
B. USE AND MIX THE SPECIFIED QUANTITIES (% BY WEIGHT) OF THE FOLLOWING NSA SIZE CLASSES OF ROCK AND STONE:

E. Obligations of Ownership. Grantor is responsible for any real estate
taxes, assessments, fees, or charges levied upon the Property. Grantor shall
keep the Property free of any liens or other encumbrances for obligations
incurred by Grantor, except those incurred after the date hereof, which are
expressly subject and subordinate to the Conservation Easement. Grantee shall
not be responsible for any costs or liability of any kind related to the ownership,

G. Extinguishment. In the event that changed conditions render
impossible the continued use of the Conservation Easement Area for the
conservation purposes, this Conservation Easement may only be extinguished,
in whole or in part, by judicial proceeding.

H. Eminent Domain. Whenever all or part of the Conservation
Easement Area is taken in the exercise of eminent domain so as to

Easement, Grantor and Grantee shall join in appropriate actions at the time of
such taking to recover the full value of the taking, and all incidental and direct
damages due to the taking.

I. Proceeds. This Conservation Easement constitutes a real property
interest immediately vested in Grantee. In the event that all or a portion of the

enforce this Conservation Easement, or if Grantee ceases to be a qualified
grantee, and if within a reasonable period of time after the occurrence of one of
these events Grantee fails to make an assignment pursuant to this
Conservation Easement, then the Grantee’s interest shall become vested in
another qualified grantee in accordance with an appropriate proceeding in a
10

court of competent jurisdiction.

L. Amendment. This Conservation Easement may be amended, but
only in a writing signed by all parties hereto, and provided such amendment
does not affect the qualification of this Conservation Easement or the status of
the Grantee under any applicable laws, and is consistent with the conservation
purposes of this grant.

to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the assessment area (5M),
and within 2 miles and within the watershed draining to the assessment area (2M).
WS 5M 2M
A A A > 10% impervious surfaces

C C C ≥ 20% coverage of pasture
D D D ≥ 20% coverage of agricultural land (regularly plowed land)
E E E ≥ 20% coverage of maintained grass/herb
F F F ≥ 20% coverage of clear-cut land

D D From 10 to < 50 acres
E E < 10 acres
F F Wetland type has a poor or no connection to other natural habitats

13b. Evaluate for marshes only.
Yes No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands.
14. Edge Effect – wetland type condition metric (skip for all marshes and Estuarine Woody Wetland)
May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include
non-forested areas ≥ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors, and clear-cuts. Consider
the eight main points of the compass. Artificial edge occurs within 150 feet in how many directions? If the assessment area is clear cut,

Mitchell,
I completed a follow up visit to the site on March 14th to add additional small wetland pockets as we
discussed and gather more information on the stream start point above the pond. Five very small
pockets of wetland were added within seepage areas in or adjacent to streamside areas. I have
included Wetland forms, photographs, and updated figures and areas/lengths for these features.
Also as discussed, stream lengths were updated to reflect survey information collected by Key
Mapping and Surveying for the mitigation site.

Saturday March 9th was the last previous rainfall event on site, so 4 full days without precipitation
had passed prior to my visit on the 14th. The stream origin point that was included in the original PJD
submittal was once again the start of S100 – see the included pictures of the area. No flow from the
old farm pond above this origin point persisted, and very little water remained up above the origin
point. The water remaining in the old pond was very shallow, 1” or less, and stagnant.
Attached to this email is the updated ORM spreadsheet and updated feature shapefiles including
surveyed streams on site, updated conservation easement, and updated wetland boundaries. I have
reattached the report as with the updated photographs, data sheets, and table. If you require any
further information please reach out and I’ll provide it to you as soon as possible.
Thank you and have a great day.

Re: NCIRT Initial Review of the WLS Slowplay Umbrella Mitigation Banking Instrument
and Mitigation Site Prospectus

Ms. Catherine Roland
Water & Land Solutions, LLC
7721 Six Forks Road, Suite 130
Raleigh, NC 27615

Dear Ms. Roland:
This letter is regarding your prospectus document dated March 2023, for the proposed
WLS Slowplay Mitigation Banking Instrument and associated Mitigation Site. The
proposal consists of the establishment and operation of a private commercial mitigation
bank, and the associated 20-acre WLS Slowplay Mitigation Site, located southwest of
Grassy Ridge Lane in Taylorsville, Alexander County, North Carolina (35.852430° N, -
81.148672° W). The proposed WLS Slowplay Mitigation Site would include stream
restoration and enhancement within the Catawba River watershed (8-digit hydrologic unit
code (HUC): 03050101).

The Corps determined the Prospectus was complete and issued a public notice (P/N
# SAW-2023-00725) on April 17, 2023. The purpose of this notice was to solicit the
views of interested State and Federal agencies and other parties either interested in or
affected by the proposed work. Incorporated in this email and attached are comments
received in response to the public notice from the North Carolina Department of Natural
and Cultural Resources State Historic Preservation Office, NC Wildlife Resource
Commission and the US Army Corps of Engineers.

The Corps has considered the comments received from members of the Interagency
Review Team (IRT) and information that was discussed during an IRT site review on
June 21, 2023 (see site visit meeting minutes attached). We have determined that the
proposed umbrella mitigation bank appears to have the potential to restore aquatic
resources within the 8-digit HUC 03050101 of the Catawba River Basin; however, we
request that you address the enclosed agency concerns in the draft mitigation plan.

Please provide a response to the attached comments with your draft mitigation plan
submittal. We appreciate your interest in restoring and protecting waters of the United
States. If you have questions regarding this letter, please contact me at [phone]
or by email at [e-mail].

Memorandum to the Record
August 7, 2023

Agency Comments for the WLS Slowplay Mitigation Bank (SAW-2023-00725)
Prospectus in Alexander County, North Carolina.

David McHenry, NCWRC:
Please consider a couple follow-up thoughts for Slowplay that I perhaps mentioned in the field
on June 21, 2023:
1) Rock structures or riffles in S103, S105, and S100-RI (as I believe the sponsor is intending to
include in the design) is recommended given the relative steepness of those
reaches/watersheds, the removal of the big pond on RI, and proximity of these reaches to
upper pasture areas where cattle use is more concentrated. I believe basins or other BMPs at
the head of these, or at least RI, was mentioned by someone and should be worthwhile
particularly if cattle use of the pastures increases.
2) S100-R4 (the possible Hexastylis ? reach) had good riparian canopy tree cover worth
keeping. I don’t think I mentioned this, but maybe some armored scour holes would be
worthwhile just inside the easement where those rills enter S100-R4 from the north side
(?).
3) Repair of the bank blow-out on R300 should be included.
4) If only minor cross-sectional changes to S200 shake-out, then it would be good to avoid
some undisturbed sections of riparian vegetation using targeted work access and work
points. Removal of tree trunk/canopy, but not stumps, is recommended on immediate
streambanks where excavation or equipment caused root damage is suspected.

Steve Kichefski, USACE:
The following comments are considered in addition to the site meeting minutes.
1. Small streams S105 and S103 need work and different approaches were discussed. S103
had bedrock, but Chris felt restoration needed to match the P1 approach to S100. There is
risk that they could lose jurisdiction when lifted, so include flow gauges and justify the
approach proposed. Consider expanding the CE if needed to provide enough space to
include BMP’s.
2. S104: EII is appropriate, but again getting enough buffer to stabilize is recommended.
3. Existing vegetation present along various portions of the project (S100, S101, S200, S201
& S300). Some shaded areas or heavily treated invasive areas may justify additional
planting in understory or to fill gaps. It was recommended to be clear which portions will
be planted in order to justify ratios proposed and what performance metrics would apply.
S100-R4 is a good example of a reach that may need minimal veg work and modified
ratio.
4. S201: This reach was clearly degraded/incised; however concern was expressed that even
if lifted it would remain a confined channel. It has steep slopes with established veg so
care is needed to keep slopes stable. This channel has limited functional uplift and was
justified partially due to the P1 lift needed on S200 and matching the channel elevation at
their confluence. Justify the approach and ratio of this reach with functional uplift in
mind and take care with the existing vegetation on the steep slopes for stabilization.
5. S200: Restoration needed, however see previous comments on existing vegetation both
for keeping slopes stable and detailing planting/veg performance metrics along with
justifying proposed ratios.

Subject: NCIRT Prospectus Site Meeting
Date Prepared: June 22, 2023
Meeting Date and Time: June 21, 2023 at 9:30 am
Meeting Location: On Site (Alexander County, NC) 35.852430°, -81.148672°
Attendees: USACE: Steve Kichefski and Erin Davis (NCIRT)

These meeting minutes document notes and discussion points from the North Carolina Interagency
Review Team (NCIRT) Prospectus Site Meeting for the Slowplay Mitigation Project (Catawba River Basin,
CU03050101). The proposed bank site is located in Alexander County, North Carolina. The meeting began
at 9:30 am with a general summary of the overall project concepts. After the site overview, attendees
toured the project site to review existing conditions and proposed mitigation types, restoration and
enhancement approaches, and design concepts. In general, the project site review notes are presented
below in the order they were discussed/visited.

General/Before Site Walk
• Erin asked if the second crossing on S100-R4 was required. WLS explained that it was
requested by the landowner in order for them to have access to the other portion of their
property.
S100-R1
• The site visit started on S100-R1. The group walked to the top of the pond at an existing
culvert crossing.
• Erin asked if WLS planned to install a BMP at the top of the pond inside the CE. Chris
responded that a BMP would be located within the CE above the junctional stream call and
that cattle will be permanently fenced out across the entire project.
• The group discussed the design plan for the pond area. Chris explained that the pond dam(s)
and culverts would be removed along with any unsuitable soil. The design would involve a
combination PI and PII approach to restore natural valley contours across the remnant pond

waterlandsolutions.com | 7721 Six Forks Rd, Ste 1130, Raleigh, NC 27615 | 919-614-5111
bottom. WLS will design a step-pool channel to accommodate the steep drop across the
existing impoundment.
• Erin asked about the cut/fill and if Chris thought the reach would balance. Chris stated that
getting the earthwork to balance was the goal and if there was excess dirt that it would most
likely get spread across the adjacent side slopes and stabilized accordingly.
• The group discussed the use of both rock and wood structures for channel stability. Chris
stated that he will incorporate wood structures (angled log drops and woody riffles) based on
material availability, but rock structures will be utilized in steeper sections. Steve noted that
woody structures, including toe wood, should be submerged whenever possible. Chris added
that it’s important to maintain surface flow across remnant pond bottom and mixing suitable
clay soil will help promote saturation to keep wood structures from dry rotting.
• The group then walked below the pond dam. The IRT agreed that restoration was the best
approach in this location.
• Erin suggested WLS watch for the possibility of a monoculture of Virginia Pine on the lower
end of S100-R1 and the upper portion of S200-R2.
S105
• The group discussed how this reach was fed by a seep. Kayne discussed that WLS would design
a step-pool channel that would tie into the main tributary (S100-R1). The IRT agreed with the
proposed design approach for S105.
S103
• Maria asked if there was WLS had considered installing an in-line BMP at the top of the reach.
The group discussed that depending on where the jurisdictional call is made the CE may be
extended, if necessary.
• Erin suggested that it might be risky to claim jurisdictional stream credit above the existing
headcut.
• Erin asked for a flow gauge on S103.
• The group discussed the design approach, Erin and Steve expressed that they believed the
reach was more appropriate for EII given the existing bedrock knickpoints. Kayne disagreed
that the reach should at least be EI with the proposed channel work, buffer planting, BMP
and cattle exclusion. Chris stated that the best approach would be restoration and he would
prefer a shallow PII design approach. Steve stated that WLS needed to justify the approach
and credit ratio for S103.
S104
• The group walked down to S104. It was agreed that EII approach was an appropriate
treatment for this reach.
• Steve suggested that when WLS submits the PJD that we go to the county contact first, but
that we copy him on the email submittal.
S100-R3
• Erin suggested that we add a table into the mitigation plan that summarizes the mitigation
approach and the credit ratios for the total length of restoration and enhancement proposed
in this reach. She stated that it would be helpful to split the reach sections and proposed
credit ratios to match the proposed level of work.

waterlandsolutions.com | 7721 Six Forks Rd, Ste 1130, Raleigh, NC 27615 | 919-614-5111
• Erin and Steve stated that we need to make our vegetation plan very clear. If there is
established vegetation, WLS needs to make sure it is marked in the plans/figures. Different
success thresholds can be used in areas of understory planting. Erin suggested a stem survival
percentage threshold.
• Erin stated that WLS can propose different monitoring criteria where we are only planting
understory vegetation.
S101/S102
• The IRT agreed with the restoration approach in this area.
• Erin suggested we run the buffer tool, if possible, to capture more stream credits.
• Maria, Erin, and Steve suggested that WLS consider having the proposed stream crossings as
internal crossing in the CE deed vs. a break outside of the CE. WLS stated we would consider
including language in the CE deed that allows them to be used for farm crossings.
S100-R4
• The group walked the entire S100-R4 reach.
• Erin stated that she did not think a 2.5:1 ratio was appropriate EII for this reach and that WLS
would need to justify the credit ratio for this reach.
S300
• The group walked to the upper section near the blown out culvert. Steve commented that the
main stem was short and disconnected, but the channel was unstable with eroding banks in
the localized area. Kayne noted that the reach condition improves further downstream and
the IRT did not think a 2.5:1 ratio was appropriate for the entire reach.

S201
• The group then drove across to S201/S200 confluence. There was a group discussion on how
far WLS was going to raise the deepened channel and grade stable benches with side slopes.
The group agreed that although significant work is being proposed for a short reach, there
was some benefit to doing full restoration since the work also includes buffer planting,
invasive treatment (kudzu and multiflora rose) and adding a BMP to reduce sediment from
highly erodible soils.
S200
• The group walked up to the large headcut on S200. There was a discussion about the steep
slopes and vegetated buffer in this area. The group also discussed the excess sediment above
the crossing and how WLS would remove and prevent more entering the system during the
design and construction.
• Chris discussed that the existing crossing would be removed and excess sediment would be
excavated prior to channel restoration. Further upstream, existing trees of significance would
be saved, and the design approach would involve minimizing buffer disturbance with strategic
structure placement to improve bedform/step-pool morphology rather than denude entire
swath of vegetation along the reach.

Summary
•Overall, the IRT members agreed the project is suitable to provide compensatory mitigation,
provided it is properly justified in the mitigation plan.
•WLS will provide a Draft Mitigation Plan as the next step in the project.

federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through IPaC by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a biological

▪
evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that
listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found in the "Endangered
Species Consultation Handbook" at: https://www.fws.gov/sites/default/files/documents/
endangered-species-consultation-handbook.pdf
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Endangered Species Act (ESA), there are additional responsibilities under the
Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to
protect native birds from project-related impacts. Any activity, intentional or unintentional,
resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by
the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more
information regarding these Acts, see Migratory Bird Permit | What We Do | U.S. Fish & Wildlife
Service (fws.gov).
The MBTA has no provision for allowing take of migratory birds that may be unintentionally
killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to
comply with these Acts by identifying potential impacts to migratory birds and eagles within
applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan
(when there is no federal nexus). Proponents should implement conservation measures to avoid
or minimize the production of project-related stressors or minimize the exposure of birds and
their resources to the project-related stressors. For more information on avian stressors and
recommended conservation measures, see https://www.fws.gov/library/collections/threats-birds.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies
to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities
that might affect migratory birds, to minimize those effects and encourage conservation measures
that will improve bird populations. Executive Order 13186 provides for the protection of both
migratory birds and migratory bird habitat. For information regarding the implementation of
Executive Order 13186, please visit https://www.fws.gov/partner/council-conservation-
migratory-birds.
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Code in the header of
this letter with any request for consultation or correspondence about your project that you submit
to our office.

PROJECT SUMMARY
Project Code:2024-0064174
Project Name:Slowplay Mitigation Project
Project Type:Mitigation Development/Review - Mitigation or Conservation Bank
Project Description:The project will restore and enhance approximately 6,258 linear feet of
stream. Stream restoration activities will include restoring appropriate
dimension, pattern, and profile to reconnect the streams to their active
floodplains. Stabilization structures will be installed, which will also
provide habitat. An existing open water farm pond will be drained, and
the stream channel will be restored through this area. Native riparian
buffers (trees) will be planted to a minimum of 50-feet from the proposed
top of bank where no canopy currently exists. A majority of the stream
buffers are already partially or fully forested. No wetland mitigation or
creation of open waters will take place on the project site.

Project Name: Slowplay Mitigation Project

Federal Nexus: yes
Federal Action Agency (if applicable): Army Corps of Engineers

Subject:Record of project representative’s no effect determination for 'Slowplay Mitigation
Project'

Dear Alyssa Davis:
This letter records your determination using the Information for Planning and Consultation
(IPaC) system provided to the U.S. Fish and Wildlife Service (Service) on March 18, 2024, for
'Slowplay Mitigation Project' (here forward, Project). This project has been assigned Project
Code 2024-0064174 and all future correspondence should clearly reference this number. Please
carefully review this letter.
Ensuring Accurate Determinations When Using IPaC
The Service developed the IPaC system and associated species’ determination keys in accordance
with the Endangered Species Act of 1973 (ESA; 87 Stat. 884, as amended; 16 U.S.C. 1531 et
seq.) and based on a standing analysis. All information submitted by the Project proponent into
IPaC must accurately represent the full scope and details of the Project.
Failure to accurately represent or implement the Project as detailed in IPaC or the Northern
Long-eared Bat Rangewide Determination Key (Dkey), invalidates this letter. Answers to certain
questions in the DKey commit the project proponent to implementation of conservation
measures that must be followed for the ESA determination to remain valid.
Determination for the Northern Long-Eared Bat
Based upon your IPaC submission and a standing analysis, your project has reached the
determination of “No Effect” on the northern long-eared bat. To make a no effect determination,
the full scope of the proposed project implementation (action) should not have any effects (either
positive or negative), to a federally listed species or designated critical habitat. Effects of the
action are all consequences to listed species or critical habitat that are caused by the proposed
Project code: 2024-0064174 IPaC Record Locator: 484-140258603 03/18/2024 16:32:47 UTC

action, including the consequences of other activities that are caused by the proposed action. A
consequence is caused by the proposed action if it would not occur but for the proposed action
and it is reasonably certain to occur. Effects of the action may occur later in time and may
include consequences occurring outside the immediate area involved in the action. (See § 
402.17).
Under Section 7 of the ESA, if a federal action agency makes a no effect determination, no
consultation with the Service is required (ESA §7). If a proposed Federal action may affect a
listed species or designated critical habitat, formal consultation is required except when the
Service concurs, in writing, that a proposed action "is not likely to adversely affect" listed species
or designated critical habitat [50 CFR §402.02, 50 CFR§402.13].
Other Species and Critical Habitat that May be Present in the Action Area
The IPaC-assisted determination for the northern long-eared bat does not apply to the following
ESA-protected species and/or critical habitat that also may occur in your Action area:
Bog Turtle Glyptemys muhlenbergii Similarity of Appearance (Threatened)
Dwarf-flowered Heartleaf Hexastylis naniflora Threatened
Monarch Butterfly Danaus plexippus Candidate
Tricolored Bat Perimyotis subflavus Proposed Endangered

You may coordinate with our Office to determine whether the Action may affect the animal
species listed above and, if so, how they may be affected.

Next Steps
Based upon your IPaC submission, your project has reached the determination of “No Effect” on
the northern long-eared bat. If there are no updates on listed species, no further consultation/
coordination for this project is required with respect to the northern long-eared bat. However, the
Service recommends that project proponents re-evaluate the Project in IPaC if: 1) the scope,
timing, duration, or location of the Project changes (includes any project changes or
amendments); 2) new information reveals the Project may impact (positively or negatively)
federally listed species or designated critical habitat; or 3) a new species is listed, or critical
habitat designated. If any of the above conditions occurs, additional coordination with the
Service should take place to ensure compliance with the Act.
If you have any questions regarding this letter or need further assistance, please contact the
Asheville Ecological Services Field Office and reference Project Code 2024-0064174 associated
with this Project.

DETERMINATION KEY RESULT
Based on the information you provided, you have determined that the Proposed Action will have
no effect on the Endangered northern long-eared bat (Myotis septentrionalis). Therefore, no
consultation with the U.S. Fish and Wildlife Service pursuant to Section 7(a)(2) of the
Endangered Species Act of 1973 (87 Stat. 884, as amended 16 U.S.C. 1531 et seq.) is required
for those species.
QUALIFICATION INTERVIEW
Does the proposed project include, or is it reasonably certain to cause, intentional take of
the northern long-eared bat or any other listed species?

Note: Intentional take is defined as take that is the intended result of a project. Intentional take could refer to
research, direct species management, surveys, and/or studies that include intentional handling/encountering,
harassment, collection, or capturing of any individual of a federally listed threatened, endangered or proposed
species?
No
The action area does not overlap with an area for which U.S. Fish and Wildlife Service
currently has data to support the presumption that the northern long-eared bat is present.
Are you aware of other data that indicates that northern long-eared bats (NLEB) are likely
to be present in the action area?

Bat occurrence data may include identification of NLEBs in hibernacula, capture of
NLEBs, tracking of NLEBs to roost trees, or confirmed NLEB acoustic detections. Data
on captures, roost tree use, and acoustic detections should post-date the year when white-
nose syndrome was detected in the relevant state. With this question, we are looking for
data that, for some reason, may have not yet been made available to U.S. Fish and Wildlife
Service.
No
Does any component of the action involve construction or operation of wind turbines?

Note: For federal actions, answer ‘yes’ if the construction or operation of wind power facilities is either (1) part
of the federal action or (2) would not occur but for a federal agency action (federal permit, funding, etc.).
No
Is the proposed action authorized, permitted, licensed, funded, or being carried out by a
Federal agency in whole or in part?
Yes
Is the Federal Highway Administration (FHWA), Federal Railroad Administration (FRA),
or Federal Transit Administration (FTA) funding or authorizing the proposed action, in
whole or in part?
No

Are you an employee of the federal action agency or have you been officially designated in
writing by the agency as its designated non-federal representative for the purposes of
Endangered Species Act Section 7 informal consultation per 50 CFR § 402.08?

Note: This key may be used for federal actions and for non-federal actions to facilitate section 7 consultation and
to help determine whether an incidental take permit may be needed, respectively. This question is for information
purposes only.
No
Is the lead federal action agency the Environmental Protection Agency (EPA) or Federal
Communications Commission (FCC)? Is the Environmental Protection Agency (EPA) or
Federal Communications Commission (FCC) funding or authorizing the proposed action,
in whole or in part?
No
Is the lead federal action agency the Federal Energy Regulatory Commission (FERC)?
No
Have you determined that your proposed action will have no effect on the northern long-
eared bat? Remember to consider the effects of any activities that would not occur but for
the proposed action.

If you think that the northern long-eared bat may be affected by your project or if you
would like assistance in deciding, answer “No” below and continue through the key. If you
have determined that the northern long-eared bat does not occur in your project’s action
area and/or that your project will have no effects whatsoever on the species despite the
potential for it to occur in the action area, you may make a “no effect” determination for
the northern long-eared bat.

Note: Federal agencies (or their designated non-federal representatives) must consult with USFWS on federal
agency actions that may affect listed species [50 CFR 402.14(a)]. Consultation is not required for actions that will
not affect listed species or critical habitat. Therefore, this determination key will not provide a consistency or
verification letter for actions that will not affect listed species. If you believe that the northern long-eared bat may
be affected by your project or if you would like assistance in deciding, please answer “No” and continue through
the key. Remember that this key addresses only effects to the northern long-eared bat. Consultation with USFWS
would be required if your action may affect another listed species or critical habitat. The definition of Effects of
the Action can be found here: https://www.fws.gov/media/northern-long-eared-bat-assisted-determination-key-

RE: FAA Required Coordination with Airfields within a Five-Mile Radius of the Slowplay Mitigation
Project

Dear Mr. Gryder:
Water & Land Solutions LLC (WLS) is currently in the planning and design phase for the Slowplay Mitigation Site
(hereinafter referred to as “project”). The project is a stream restoration site located on a parcel that is mainly
cattle pasture. The project parcel is located approximately 4.7 miles from the Gryder-Teague Airport, of which you
are the listed owner/manager. Per an FAA Advisory Circular (AC No: 150/5200-33C), updated February 2020, WLS
is required to reach out to officials for a consultation for all projects that have an airfield within a five-mile radius.
The purpose of the project is to provide mitigation credits to compensate for unavoidable impacts to the Waters of
the U.S. authorized under Section 404 of the Clean Water Act and all applicable state statutes. These credits will be
sold to anyone needing to make unavoidable impacts to stream in the Catawba River watershed.
The project will restore and enhance approximately 6,258 linear feet of stream. Stream restoration activities will
include restoring appropriate dimension, pattern, and profile to reconnect the streams to their active floodplains.
Stabilization structures will be installed, which will also provide habitat. An existing open water farm pond will be
drained, and the stream channel will be restored through this area. Native riparian buffers (trees) will be planted
to a minimum of 50-feet from the proposed top of bank where no canopy currently exists. A majority of the stream
buffers are already partially or fully forested. No wetland mitigation or creation of open waters will take place on
the project site.
I have included the public notice for your reference. If you have any questions or concerns, please reach out either
by email or phone by March 15, 2024. If we do not hear from you by this date, we will assume you have no concerns
regarding the project.
Thank you,
