Section D. Executive Summary
In response to RFP Number 16-20190201, Clearwater Mitigation Solutions, LLC presents the following
proposal for the Cool Run Mitigation Site, which will provide high quality compensatory mitigation for
authorized stream and riparian wetland impacts credited through the NC DMS in -lieu -fee program
and occurring within the Lumber River Hydrologic Unit Code (HUC) 03040207. The project team
consists of highly experienced professionals with diverse backgrounds that lend to a multi -disciplinary
approach to the mitigation effort. The team is led by Mr. Kevin Yates of Clearwater Mitigation
Soutions, LLC. The Project Manager will be Mr. Christian Preziosi with Land Management Group
(LMG). Grant Lewis with Axiom Environmental, Inc. (AXE) will serve as the lead for stream design and
construction management. Wes Newell of Waterway Design Build, LLC will provide construction
oversight and management.
The restoration areas are located along Cool Run and an unnamed headwater tributary that flow
directly into the Shallotte River. The Upper Shallotte River watershed (14-digit HUC 03040207020060)
is a Target Local Watershed (TLW) of the Lumber River Basin. The upper portion of the Shallotte River
has exhibited significant water quality impairments associated with low dissolved oxygen (DO) and pH,
possibly due to swamp water conditions. The lower portions of the Shallotte River are closed for
shellfish due to fecal coliform bacteria. The proposed project promotes the goals of the Lumber RBRP
(2008) and specifically the Upper Shallotte River TLW by addressing the priority of restoring
headwater stream channels and riparian wetlands. The anticipated functional uplift to be provided by
the project will have direct benefits to on -site stream and wetlands, as well as to the downstream
receiving waters and to the broader ecological health of the Upper Shallotte River watershed.
CMS has secured a real estate option agreement for the purchase of easement rights on one parcel in
Brunswick County, North Carolina, near the Town of Shallotte. Two options for the project are
proposed for mitigation credit generation:
Option 1 encompasses the entire 25.15 acres easement area and can produce 2,208 SMUs and
14.3 WMUs.
Option 2 also encompasses the entire 25.15 easement area, and can yield the minimum of
2,000 SMUs and 8.0 WMU, representing the requested mitigation credits in RFP #16-20190201.
Figure 9 (Appendix A) depicts the proposed easement area, which is identical for Option 1 and Option
2. Option 1 provides an additional 208 SMUs and 6.3 WMUs above the requested amount in RFP #16-
2019201. Both options provide for restoration and protection of aquatic resources with a conservation
easement and will result in net gains in hydrology, water quality, and habitat functions at the Site.

Project Manager Qualifications and Experience
CMS recognizes that the Project Manager will serve an important role on a full delivery project. An
individual with a broad range of skills linking together budgetary and personnel management with all
the components of a restoration project (assessment, survey, design, construction, permitting,
monitoring, agency and credit delivery) will be needed to successfully oversee and implement this
project. The individual will also need to be experienced in completing large scale restoration projects
with time -sensitive design and construction deliverables.
CMS's project manager on this project will be Kevin Yates. Mr. Yates has over 17 years of experience
in water resources, stream, wetlands, stormwater, riparian buffer, environmental restoration, and
mitigation. Mr. Yates began working for the US Army Corps of Engineers, Wilmington District in 2001,
while attending graduate school at the University of North Carolina at Wilmington, graduating with a
Masters of Marine Science in 2004. During this period, Mr. Yates worked as an intern in the USACE
Wilmington Regulatory Field Office and full-time in the USACE Raleigh Regulatory Field Office as a
Regulatory Project Manager through May, 2005. Mr. Yates went into private environmental
consulting in 2005, with a large multi -disciplinary engineering/design firm, McAdams Company,
based in Durham, North Carolina. Mr. Yates was awarded the McAdams Company trailblazer award
in 2006 for chartering and leading these new environmental consulting services for the firm, where
he served as the Senior Environmental Consultant and Project Manager through 2018. For the natural
Response to Request for Proposal #16-20190201 2 1 P a g e
Section E — Corporate Background and Experience
resources group at McAdams, Mr. Yates managed staffing, budgeting, billing, project scheduling,
environmental field investigations (including stream, wetland, buffer investigations), and any
required wetland, stream, and riparian buffer permitting (through USACE/DWR/CAMA). In addition,
Mr. Yates prepared and implemented compensatory mitigation plans, prepared environmental
assessment documents under NEPA/SEPA requirements, and was routinely asked to review and
comment on pending federal and state legislation, as well as local ordinances.
Mr. Yates has worked on a broad range of projects during his tenure at McAdams which has helped
to give him a well-rounded approach to problem solving and a unique ability to manage the complex
needs of large scale restoration projects. Equipped with first-hand knowledge of assessment
techniques, design understanding and construction management and implementation experience,
Mr. Yates has been challenged to manage the design and construction elements of various
environmental mitigation projects completed in both urban and rural settings. More recently, Mr.
Yates formed Clearwater Mitigation Solutions in 2015 and has since developed and managed a $2.1
million, 71-acre turn -key riparian and non -riparian wetland mitigation site known as the Lowlands
Wetland Mitigation Site, in the Hydrologic Unit 03020201 (Neuse 01) service area. CMS is currently
under contract with DMS on a full -delivery riparian buffer mitigation site, with the CMS/LMG team
working on this site, known as the Wingfoot Site in Pitt County.
Mr. Yates' philosophy on developing successful environmental design and construction projects is to
promote ownership of the project from the ground up. This involves informing and training
contractors, landowners, regulatory staff, project owners and other project stakeholders through
diligent communication and involvement. As an owner/operator, Mr. Yates understands that the key
to managing large scale projects with aggressive time requirements is to stay in front of potential
problems, foster active partnering among team members and to surround yourself with hard
working, skilled individuals who all have a stake in the success of the project. The CMS / LMG Team
has been formed with these factors in mind and will be dedicated to the success of the project.

Carolina:
Lowlands Wetland Mitigation Site (Johnston County, North Carolina)
Clearwater Mitigation Solutions' (CMS) Lowlands Wetland Mitigation Site is a 71-acre, turn -key
project which will provide wetland mitigation credits to Dominion Energy Transmission, Inc. (DETI) as
part of DETI's Permittee Responsible
Mitigation Plan (PRM) to compensate for
unavoidable impacts to wetlands associated
with the Atlantic Coast Pipeline Project (ACP),
within the Hydrologic Unit 03020201 (Neuse
01) service area. All wetland mitigation units
generated within the Site are to be utilized by
DETI for the ACP within this service area. The
project area is approximately 71.2 acres, of
which 65.3 acres will include some form of
wetland re-establishment, enhancement, or
preservation with the remaining 5.9-acres of
Response to Request for Proposal #16-20190201 6 1 P a g e
Section E — Corporate Background and Experience
uplands and non-credit area to be included within the overall conservation easement as an upland
buffer. CMS identified the site, which comprised multiple land owners, negotiated with land owners,
conducted initial groundwater level monitoring, identified and coordinated all survey items, helped
develop and coordinate contracts with DETI's legal team and the CMS legal team, developed a
mitigation plan along with the design team which was approved by the USACE in 2017 as part of
DETI's compensatory mitigation plan for the ACP. Clearwater Holdings I, a subsidiary of CMS, acquired
the conservation easement, with CMS overseeing construction and planting in early 2018.
Ultimately, the wetland mitigation project will improve the overall function, habitat, and integrity of
the degraded and drained wetlands, while preserving existing higher quality wetlands, with primary
goals to:
1. Restore the primary wetland functions and
values appropriate for this section of the
Neuse River Lowlands.
Objective: Re-establishment and conversion of the
existing agricultural fields exhibiting hydric soil
characteristics to a bottomland hardwood
wetland.
2. Improve sediment retention and capacity for
nutrient removal to offset historic agricultural
practices.
Objective: Filling discharge ditches, traditionally
used in nutrient -enriched row crop production.
Planting with native bottomland hardwood
species to prevent sediment loss and provide for
nutrient uptake.
3. Restoration of the attendant hydrologic and
biologic functions of a bottomland hardwood forest.
Objective: Restoration of appropriate bottomland
hardwood wetland hydrology through filling of site
ditches and restoring connectivity with adjacent
surface waters. Improve surface water storage by
tilling compacted soil to create microtopography. .
4. Restore and Enhance native bottomland hardwood
forest.
Objective: Plant native tree and understory species,
including Atlantic White Cedar and Bald Cypress,
within re-establishment and enhancement portions of
the Site.
S. Permanently protect existing higher quality bottomland hardwood forest, in addition to the
remainder of the project area.
Objective: Establish a perpetual conversation easement over the Site.
Construction was completed in February 2018, with the goal to re-establish 23.1-acres of riparian
wetlands, enhance 5.1 acres of riparian and 14.3 acres of non -riparian wetlands, and preserve 22.8-
acres of non -riparian wetlands within the Site producing 24.25 riparian and 9.33 non -riparian wetland
mitigation units (WMUs). The as -built data collection and survey has been completed and the site has

On behalf of Duke University, CMS staff served as
the lead consultant for environmental site
investigations, mitigation plan development,
permitting, implementation, and monitoring of the
Duke University Campus Drive Stream Mitigation
Project, as part of their compensatory mitigation
conditions of a 404/401 Individual Permit. The
project area consists of an unnamed tributary to
Sandy Creek, running along Campus Drive, within
Duke University's Main Campus, which ultimately
drains to Jordan Lake within the Cape Fear (HUC
03030002).
The project included restoration and enhancement of approximately 3,249 linear feet of existing
highly degraded and poorly functioning perennial stream channel for a total of 2,941 stream
mitigation units (SMUs), within Duke University's Main Campus. The project also ties into existing
Clean Water Management Trust Fund stream restoration projects downstream of the same unnamed
tributary, which will incorporate a more watershed -based design approach. The Campus Drive stream
restoration project created an approximate 9,500 linear foot corridor of restored stream and riparian
corridor, from Campus Drive to the Duke University golf course, protected in perpetuity. CMS staff
worked with Durham County Soil and Water Conservation District which agreed to hold the
Conservation Easement to provide, third -party, long-term assurance to the success of the project.
Although this is an urbanized setting, most of the impervious surface within the watershed is built -
out and there would be little to no
new impervious surface draining to
the proposed project. The restoration
plan also incorporated stormwater
management devices, plunge pools,
and stormwater wetlands in locations
along the mitigation corridor where
stormwater runoff is currently
untreated. Due to the challenging
conditions of stream restoration in

In response to authorized wetland and stream impacts associated with the PCS Phosphate Mine
Expansion, Land Management Group was the lead consultant in mitigation plan development,
permitting, implementation, and monitoring of the Rutman Creek Watershed Restoration Project (a
permittee-responsible mitigation project). The mitigation project consisted of landscape -scale
restoration of wetlands, streams, and riparian buffer at the headwaters of Rutman Creek, a second -
order tributary of the Pungo River located
within the Tar -Pamlico River Basin. The
entire project restored approximately 3,342
acres of wetlands and 8,793 If of zero -order
stream reaches. An additional 129 acres of
wetlands and 7,994 If of stream channel
were enhanced via re-establishment of
natural hydroperiods and flow. LMG was
the lead in agency coordination throughout
all stages of implementation and
monitoring of the project. Five years of monitoring have been recently completed for the project and

Land Management Group, Inc. served as the lead consultant for environmental site investigations,
design, permitting, implementation, and monitoring of the Bachelors Delight Stream and Wetland
Mitigation Bank. The Bank is located approximately 2 miles north of the City of Jacksonville in Half
Moon, Onslow County, North Carolina. The site is located within the New River watershed (14-digit
HUC 030300001010040) (an identified Targeted Local Watershed of the White Oak River Basin). The
Bank site (approximately 363 acres) consists predominantly of channelized headwater wetland and
stream systems that have been historically altered as a result of silvicultural and agricultural
management practices. Streams and waterbodies within the watershed are susceptible to
impairment from nutrient loading and low ambient dissolved oxygen (DO) concentrations.

In conjunction with the stream designer
(HDR, Inc.), LMG oversaw construction
management and planting. Functional
uplift to stream reaches and associated
adjacent wetlands have been achieved via
the re-establishment of natural
hydrologic and vegetative conditions that
existed prior to the initiation of intensive
land management in the early 1970s. Re-
establishment of native vegetative
communities suited to the landscape
position and soil types of the project area provide for enhanced feeding and refuge habitat for
resident and migratory species. Restoration and protection (via the conservation easement deed) of
the riparian and non -riparian wetlands provides a habitat corridor from expansive wetland flats of
Hofmann Forest to downstream bottomland hardwood forests of Bachelors Delight Swamp and New
River.

Section F. Project Organization
Section G. Technical Approach
1. Project Goals and Objectives
The over -arching goal of the Cool Run Mitigation Project is to provide high quality compensatory
mitigation for authorized stream, riparian wetland, and non -riparian wetland impacts credited
through the NC DMS in -lieu -fee program and occurring within the Lumber River Hydrologic Unit
Code (HUC) 03040207. The project is located within the Upper Shallotte River watershed (14-digit
HUC 03040207020060), which is a Target Local Watershed (TLW) of the Lumber River Basin. This
watershed exhibits water quality impairments associated with low dissolved oxygen (DO). In
addition, surface waters in this area are susceptible to high nutrient concentrations (N and P) that
manifest from non -point source loading associated with intensive agricultural and forestry land -use
practices. Sediment loading (associated with silvicultural and agricultural drainage) is prevalent
throughout the watershed. These impairments tend to be exacerbated by direct disturbances to
streams and wetlands (such as prior channelization of streams and historic drainage of wetlands).
The cumulative effects of such practices result in diminished nutrient uptake and nutrient/sediment
loading to down -gradient waters. Cool Run is located within an area subject to some of the highest
rates of population growth in the country'. Rapid growth and development has presented a suite
of additional stressors to water quality within the watershed including run-off associated with
increased impervious cover. While forest remains the dominant land cover at over 34%, the Long
Bay Subbasin is the most impervious subbasin in the Lumber River Basin (NC DENR 2010).
The proposed project promotes the goals of the Lumber River Basinwide Water Quality Plan (2008)
and specifically the Upper Shallotte River TLW by addressing the priority of restoring headwater
stream channels and riparian wetlands. The primary goals and objectives of this stream and
wetland restoration project focus on the following (goals listed first followed by objectives in bullet
form):
1. Improvement of hydraulic connectivity to floodplains and enhancement of flood attenuation
• Restoring the existing highly modified and incised channel using predominantly Priority 1
restoration techniques where bankfull and larger flows will more readily access the
historic floodplain;
• Restoring streams on -site using Priority I restoration techniques will enhance the Site's
ability to mitigate flood flows by reconnecting bankfull and higher flows to its historic
floodplain;
Brunswick County was recently identified as the fastest growing county in the state. According to the U.S. Census
Bureau (2017), Brunswick County's population increased by 21.8 percent, or by 23,466 people between 2010 and
July 2017. In addition, Brunswick County's metro area, which includes Myrtle Beach and Conway, was the second
fastest growing area in the country.
Response to Request for Proposal #16-20190201 11 P a g e
Section G. Technical Approach
• Removing adjacent earthen berms (spoil from historic channel modification) from the
floodplain will afford more natural valley access for floodwaters, in turn attenuating
flows and assisting in hydrating riparian areas that are largely severed from interaction
with existing stream channels; and
• Restoring riparian wetlands adjacent to the restored channels will assist in attenuating
floodwaters, thus reducing sediment and nutrient loading to downstream waters.
2. Raising near -surface groundwater hydrology in floodplain/riparian areas to assist in the
restoration of wetlands and to increase the Site's ability to uptake and store pollutant inputs
• Restoring the bed elevations of the stream channel into its relict channel will re-
establish surface water inflows and groundwater storage within riparian wetlands,
thus promoting the uptake, storage and fixation of nutrients and sedimentation from
overbank flows.
• Removing spoil from relic wetland areas will re-establish natural contours and
floodwater storage thus contributing to enhance nutrient uptake/transformation and
sediment retention.
3. Reduction of sediment loss from degraded banks that affects water quality and aquatic
habitat
• Restoring the degraded, straightened and incised stream as primarily a Priority 1
restoration where bankfull and larger flows can access the floodplain allows nutrients,
sedimentation, and debris from upstream silvicultural land use to settle within the
floodplain to a greater extent than existing conditions.
• Restoring a stable dimension, pattern, and profile by re -connecting to the relict
channel. Doing so will allow for the channel to transport and attenuate watershed
flows and sediment loads without aggrading or degrading. Priority 1 restoration will
increase flood interaction with the floodplain, thereby increasing capacity for nutrient
uptake and pollutant removal prior to discharge to downstream receiving waters.
• Stabilizing channel banks by restoring the channel to its relict location in the low point
of the valley and utilizing in -stream structures (where deemed suitable) to reduce
shearing forces on outside meander bends, and planting native vegetative species to
provide soil stability will reduce stream bank stressors.
4. Enhancement of aquatic, semi -aquatic and riparian habitat
• Restoring the channel to a sand bed system with meanders and natural structures that
promote invert scour and pool development fosters improved aquatic habitat for
benthic macroin vertebrate and fish propagation. Woody materials such as log
structures, overhanging planted vegetation and toe wood in submerged water will
Response to Request for Proposal #16-20190201 2 1 P a g e
Section G. Technical Approach
provide a diversity of shading, bed form and foraging opportunities for aquatic
organisms.
• Restoring wetland hydrology and introducing floodwaters back to the historic
floodplain will provide a diversity of habitats for semi -aquatic flora and fauna.
S. Protecting, preserving and enhancing stream and wetland habitat within and adjacent to
agricultural and silvicultural site
• Restoration and protection (via the conservation easement deed) of the riparian
wetlands provides a habitat corridor from the upper reaches of a first -order stream to
downstream bottomland hardwood forests of Shallotte River. Long-term protection is
considered particularly beneficial in light of intensive development pressures within the
subbasin and the susceptibility of downstream waters to shellfish closures (attributed
to stormwater runoff).
The anticipated functional uplift to be provided by the project will have direct benefits to on -site
stream and wetlands, as well as to the downstream receiving waters and to the broader ecological
health of the Upper Shallotte River watershed. This is particularly beneficial in light of the extent
and severity of water quality impairments of surface waters of the Shallotte River and the threat to
existing stream and wetland habitats as a result of intensive development pressures along this
stretch of the southeastern North Carolina coast.
2. Project Description
A. Site Location
The project site is located in Brunswick County, approximately five miles southwest of the city limits
of Shallotte, North Carolina and north of State Route 1316 (Old Shallotte Rd NW) (refer to Figure 1).
As indicated above, Cool Run is a first -order tributary located within the Upper Shallotte River
watershed (14-digit HUC 03040207020060), which is a Target Local Watershed (TLW) of the Lumber
River Basin (Figure 2). The riparian wetland restoration areas are situated within the floodplain of
the relict channel of Cool Run which has been historically re-routed (to the edge of the floodplain),
straightened, and deepened. The manipulated channel of Cool Run drains into the Shallotte River
approximately 2.0 river miles downstream from the project area (refer to Figure 3 and Figure 4).
B. Watershed and Water Quality Classification
Cool Run has a NC DEQ surface water classification of C; SW. The classification "C" denotes waters
protected for secondary uses such as secondary recreation, fishing, wildlife, fish consumption,
aquatic life including propagation, survival and maintenance of biological integrity, and agriculture.
"Secondary recreation includes wading, boating, and other uses involving human body contact with
water where such activities take place in an infrequent, unorganized, or incidental manner." The
"SW" classification is a supplemental classification intended to recognize those waters which have
low velocities and other natural characteristics which are different from adjacent streams.

Section G. Technical Approach
C. Physiography. Geology, and Soils
The Cool Run mitigation site is located within the Carolina Flatwoods of the Middle Atlantic Coastal
Plain Ecoregion (63h). In general, this ecoregion is characterized by nearly level coastal plain with
less relief and larger areas of poorly drained soils than the adjacent, higher elevation Southeastern
Plains to the west. The Carolina Flatwoods were covered by shallow coastal waters during the
Pleistocene, and the resultant terraces tend to consist of fine -loamy and coarse -loamy soils, with
periodically high water tables. Other areas have clayey, sandy, or organic soils, contributing to the
region's plant diversity. The region is a significant center of endemic biota, with high biological
diversity and rare species compared to adjacent regions. Artificial drainage for forestry and
agriculture is common.
Elevations of the site range from 52 ft above mean seal level (AMSL) along the northeastern
boundary to 38 ft AMSL where Cool Run exits along the southern boundary. The soils formed in
unconsolidated sand, silt, and clay deposited by water. They are nearly level to sloping. Soils of the
site consist of very poorly drained loams in drainageways to moderately well -drained loamy sands
along convex stream terraces (refer to Figure 5). Mapped soil series occurring on the site and their
associated properties are summarized in Table 1. Areas proposed for stream and riparian wetland
mitigation occur within the poorly drained Muckalee loam soil series. Profile descriptions of on -site
soil borings (prepared by a NC Licensed Soil Scientist) are provided in Appendix A.

D. Existing Conditions
1. Stream Tributaries
The property is currently managed for agricultural and silvicultural production with the majority of
the mitigation area occurring within the previously harvested floodplain of Cool Run. The natural
hydrologic conditions of the site have been historically altered by the relocation, straightening, and
Response to Request for Proposal #16-20190201 4 1 P a g e
Section G. Technical Approach
deepening of the Cool Run tributary and an unnamed tributary to Cool Run (UT-1) and subsequent
installation of several shallow surface ditches within the riparian floodplain. The altered channel
and ditches appear on historic aerial photos dating back to the 1950s (see historical site aerial
photography in Appendix B). The project site consists of the headwaters of Cool Run (a first -order
tributary of the Shallotte River), an unnamed tributary to Cool Run (UT-1), and former wetland
areas historically impacted by prescribed site drainage practices. The stream reaches and highly
degraded riparian areas lie within topographic crenulations characteristic of fluvial systems. Cool
Run appears to have been relocated and channelized in the late 1950s. UT-1 appears to have been
channelized prior to 1956. Historic channelization has resulted in the disconnection of the stream
channels from their adjacent riparian floodplain and effectively drained riparian wetlands. The
extent of the conservation easement boundary is depicted on the 1998 aerial and 2016 aerial in
Figure 6 and Figure 7, respectively. The existing conditions plan view (with stream features, NC
SAM form locations, and cross-section locations as further described below) is provided in Figure 8.
Site specific mitigation goals and objectives have been developed through the use of the North
Carolina Stream Assessment Method (NC SAM) analyses of existing stream systems at the Site (NC
SFAT 2015). Site functional assessment data forms are available upon request and model output is
included in Appendix C and is summarized in the following table. Metrics targeted to meet the Site's
goals and objectives are depicted in bold, within Table 2 below.
a. Cool Run
Cool Run enters the Site as a low -gradient, first order perennial tributary and maintains first order
status through the Site (USGS 1946). Cool Run generally flows from the northeast to the southwest
and south through the proposed mitigation site. The channel continues south along the outer,
eastern edge of an impounded pond that is on the adjacent property to the west. Cool Run flows
south across US Highway 17 into the Shallotte River (approximately 2 river miles south of the
mitigation site).
Cool Run enters the site via an incised and straightened channel that drains approximately 1.62-
miles of timberlands to the north (USGS Stream Stats). The stream is a sand -bed system that has
been highly modified in the past. Historical aerials confirm ditching of the site beginning in the late
1950s. Evidence of ditching includes spoil piles which act as berms along both banks. The channel
predominantly flows along the left valley shoulder (outside of the natural floodplain) as it enters the
site and then transects the floodplain to where it flows along the upper edge of the right valley.
The existing Cool Run channel lacks any natural meander geometry. Fortunately, the relic
(abandoned) natural channel was not filled during prior site alteration and remains throughout the
length of the valley (as evidenced through LiDAR imagery and subsequently verified through field
investigations). These relic sections of the channel will be utilized in further assessments during
determination of reference conditions and mitigation planning.
Channel bed form is absent of deeps/pools which would be commonly found in highly functional
and sinuous Coastal Plain stream channels. Channel banks are high, nearly vertical and display
lengths of bare soils that are eroding because the channel is incised below the rooting depth of
adjacent vegetation. Channel banks are high because:
• anthropogenic disturbances that have intentionally deepened the channel;
• spoil from channel modifications has been cast off to the top of bank, which raises the
ground surface along the bank and;
Response to Request for Proposal #16-20190201 5 1 P a g e
Section G. Technical Approach
• the channel has been relocated to the edge of the valley where topographical relief is
significantly greater than within the flatter valley floor.

These high banks cause the channel to be
much deeper than would be anticipated
naturally, which in -turn causes high flows to
be maintained within the channel and
reduces access to the floodplain.
Containment of higher flows within in the
channel increases shearing forces on the
vertical side slopes and channel invert which
promotes erosion.

the bank height ratios is 1.9.
Generally, the bankfull flow stage appears to be approximately at the low bank height. Geomorphic
data confirms the containment of bankfull and higher flows within the channel. Data from the
cross -sections (Appendix D) indicate that Cool Run can generally be classified as a G type stream,
which is indicative of an unstable system. It should be noted that geomorphic parameters that
influence channel classification have been significantly influenced by anthropogenic modifications.
As indicated above, the relic channel remains
relatively intact with characteristic channel
geometry and meanders throughout much of the
natural valley. However, due to the
channelization and relocation of the Cool Run
tributary, the relict channel exhibits no flow
patterns.
b. Un-named Tributary (UT)-1
A small stream channel with a relatively small
drainage area (approximately 70-acres) enters
the Site and converges with Cool Run (USGS
Stream Stats). This stream (UT-1) is denoted as
a blue line on the 1943 USGS Shallotte
quadrangle. However, valley crenulations are
only depicted on the 1990 USGS quadrangle.
Additionally, the digital elevation model (DEM)

d. Sediment Model
Sediment load modeling was performed using methodologies outlined in A Practical Method of
Computing Streambank Erosion Rate (Rosgen 2009) along with Estimating Sediment Loads using the
Bank Assessment of Non -point Sources Consequences of Sediment (Rosgen 2011). These models
provide a quantitative prediction of streambank erosions by calculating Bank Erosion Hazard Index
(BEHI) and Near -Bank Stress (NBS) along each Site reach. The resulting BEHI and NBS values are
then compared to streambank erodibility graphs prepared for North Carolina by the NC Stream
Restoration Institute and NC Sea Grant.
Streambank characteristics involve measurements of bank height, angles, materials, presence of
layers, rooting depth, rooting density, and percent of the bank protected by rocks, logs, roots, or
vegetation. Site reaches have been measured for each BEHI and NBS characteristic and predicted
lateral erosion rate, height, and length to calculate a cubic volume of sediment contributed by the
reach each year. Data forms for the analysis are available upon request and the data output is
presented in Appendix F. Results of the model are presented in Table 4 below.

2. Wetland Conditions
Wetlands within the project area have been historically altered via drainage and conversion to
timber and/or agricultural management. Surface water inflow via overbank flooding no longer
occurs with the floodplain of the channelized streams. Groundwater levels have been significantly
lowered to the extent that the adjacent riparian zone within the proposed restoration area is no
longer considered jurisdictional wetlands as evidenced by the lack of primary indicators of wetland
hydrology. This in turn has resulted in subsidence and oxidation of surface organics and has
contributed to a shift in vegetative assemblages (i.e. recruitment of drier species). In addition, the
vegetative assemblage has been historically altered from conversion to monotypic loblolly pine
plantation and subsequent harvesting. Canopy species within the immediate riparian zone (i.e.
within SO feet more or less) of the upper reach consist of sweet gum (Liquidambar styraciflua) and
red maple (Acer rubrum) (i.e. species more representative of altered sites). The understory consists
of species characteristic of drained sites such as horse sugar (Symplocos tinctoria), American
beautyberry (Callicarpa americana), dog fennel (Eupatorium capillifolium), and muscadine grape
(Vitis rotundifolia). Areas lacking wetland hydrology are targeted for wetland restoration (e.g. re-
establishment) as described further in Section 3B below.
In the downstream portion of the site, few remnant canopy specimens of characteristic species
such as tulip poplar (Lirodendron tulipifera), and swamp chestnut oak (Quercus michauxii) persist.
The sub -canopy and shrub strata in these area include fetterbush (Ilex glabra) and American holly
(Ilex opaca). However, subsidence, lack of hydrologic indicators, and the presence of vegetative
species indicative of drier conditions illustrate drainage through much of the reach within the
project area. Microtopographical depressions remain within the floodplain (including portions of
Response to Request for Proposal #16-20190201 9 1 P a g e
Section G. Technical Approach
the relic channel). These areas appear to meet the three parameters of wetland hydrology but lack
characteristic riparian wetland hydrology (i.e. intermittent to seasonal inundation with surface
water inflow from stream overbank flooding). Restoration of the Cool Run tributary to its original
location within the central portion of the valley will allow for the rehabilitation of wetlands that
have been historically impacted.
Up -gradient riparian wetland areas on the eastern edge of the valley have been disconnected from
the floodplain by a toe -slope interceptor ditch which has resulted in a lowered groundwater
condition. However, wetland hydrology of the adjacent seeps and headwater wetland areas still
persists (though with apparent reduced hydroperiods). As result, these wetland areas are targeted
for enhancement (refer to Figure 8 for the Existing Conditions Plan View).
Riparian wetlands associated with much of the reach of Cool Run are classified as Headwater Forest
wetland type that grade to Bottomland Hardwood Forest wetland type (NCWAM 2010) just south of
the mitigation site. UT-1 is classified as Headwater Forest wetland type (NCWAM 2010). The stream
reach grades to Riverine Swamp Forest down -gradient where overbank flooding would normally be
a more significant source of water in an unaltered condition. Based upon Schafale and Weakley
(1990), the riparian wetlands of the project area are considered Small Stream Swamp (Blackwater
Subtype) grading to Bottomland Hardwood Forest (Blackwater Subtype). These wetland types are
intermittently to seasonally flooded in an unaltered condition. Principal sources of hydrology are
groundwater seepage, diffuse surface flow, and overbank flooding. Downstream sections of Cool
Run would exhibit greater hydrologic input from higher frequency overbank flooding events
(NCWAM 2010).
Photographs of existing site conditions are provided in Appendix G. The limits of the proposed
restoration and enhancement are depicted in Figure 9 and are described in more detail in Section
3B below.
E. Jurisdictional Streams and Wetlands
As indicated above, historic drainage practices associated with silvicultural and agricultural
management have resulted in the interception of surface water, the lateral drawdown of
groundwater, and the reduction/removal of overbank flooding in former riparian wetland areas.
Some depressions within the floodplain (including those associated with the relict stream channel)
exhibit higher groundwater levels. In addition, up -gradient riparian wetland areas on the eastern
edge of the valley also retain indicators of wetland hydrology. These areas are considered to be
jurisdictional wetlands as regulated by the U.S. Army Corps of Engineers (USACE) and the NC
Division of Water Resources (DWR) (refer to Figure 8). No other wetlands were identified within
the project area as part of the site assessments. However, a complete wetland delineation with
USACE review and concurrence will be performed as part of the mitigation plan development. The
delineation will culminate in the issuance of a final jurisdictional determination (JD) issued by the
USACE prior to approval of the final mitigation plan.
All channels identified for single -thread or headwater stream restoration meet the definition of
jurisdictional Waters of the United States as each exhibits a continuous Ordinary High Water Mark
(OHWM). NC DWR Stream Identification Forms have been completed for each of the on -site
channels proposed for restoration. The entire length of the Cool Run is considered perennial. The
UT-1 headwater stream channel is considered intermittent.

F. Cultural Resources
Section 106 of the National Historic Preservation Act requires federal agencies to take into account
the effects of their undertakings on historic properties. LMG reviewed the State of North Carolina's
online cultural resource database (HPOWEB GIS Service) to determine if any cultural resources
and/or historic properties have been recorded within or near the project area. According to their
website, there are no sites or features listed in the National Register of Historic Places within or
adjacent to the project site. Attached is a map illustrating documented cultural and historic
resources in the vicinity of the project area (Appendix H).
G. Threatened and Endangered Species
Species with the federal classification of Endangered (E), Threatened (T), or Officially Proposed (P)
for such listing are protected under the Endangered Species Act (ESA) of 1973, as amended, and the
Bald and Golden Eagle Protection Act. The US Fish and Wildlife Service's Information, Planning, and
Consultation (IPaC) system was used to determine federally -protected species that are known to
occur in the general project vicinity (Table 5). Furthermore, a search of the North Carolina Natural
Heritage Program database was conducted to identify areas within or around the site that are
already known to support rare species. According to their files, no federally or state -protected
species are known to occur within the site. One historical record of a state -listed dragonfly has
previously been identified within a one -mile radius of the site (see Appendix H).
The presence of any plant or animal species is determined by the availability and abundance of
suitable habitat. Staff of LMG performed a limited site evaluation to identify community types
within the site that may support federally -protected species. The property is currently managed for
silvicultural and agricultural production (including recent harvesting along the majority of the
project area). Cool Runs has been channelized over the years and former wetlands areas adjacent
to the channel (proposed riparian wetland restoration) have been drained. The riparian areas (in
areas without harvesting) currently support a canopy of red maple and sweetgum with a fairly
dense subcanopy and shrub layer that supports horse sugar, American beautyberry, and American
holly, and gallberry (Ilex glabra). The riparian areas are classified as Bottomland Hardwood Forest
(NCWAM, 2010). Downstream of the project site consists of Bottomland Hardwood Forests grading
to Riverine Swamp Forest and high -order stream channels that have the potential to support
American alligator. However, these areas are located off the property. Proposed mitigation work
would not have an adverse effect on any federally -listed species.
Outside of the stream valley, the site consists of convex ridges and interstream flats and
depressions. These areas are actively managed for silvicultural and agricultural production and
generally consist of active farm fields and harvested areas. Based upon preliminary site evaluations
and findings, these areas do no support habitat suitable for listed species.
Overall, the proposed mitigation work would not have an adverse effect on any federally -listed
plant or animal species. However, headwater stream restoration will promote enhanced water
quality and habitat for aquatic and semi -aquatic species that will in turn beneficially affect listed
species such as the American alligator and bald eagle. Upon award of contract, an environmental
screening will confirm these findings.

Floodplain Development Permit as a courtesy to the County to inform them of the project.
I. Site Constraints
The site is well -suited for achieving the preferences as indicated in the RFP based upon its soil
types, landscape position, hydrology, extent of previous human alteration, lack of physical
constraints, and connectivity to relatively undisturbed bottomland hardwood forest offsite. There
are no known site constraints that would impede or adversely affect the restoration, enhancement,
or preservation of streams and wetlands of the project area.
3. Project Development
The Proposal documents one Mitigation Option for the proposed cataloging unit. See Figure 9 for
the Proposed Mitigation Map. Proposed mitigation is summarized as:
Summary of Streams
• Cool Run — Restore natural pattern, profile and dimension to approximately 2055 feet of
Cool Run within the Site limits by redirecting stream flow into the historic abandoned
channel.
• UT 1— Restore a headwater stream to approximately 370 feet of valley which constitutes UT
1 within the Site limits.
Summary of Wetlands
• Riparian Wetland Restoration — re-establish characteristic wetland hydrology via raising of
stream bed elevations and removal of spoil piles (re-establishment of surface water inflows
and groundwater storage); plant areas lacking characteristic wetland tree and shrubs;
connection of existing wetlands to floodplain and stream
• Riparian Wetland Enhancement — re-establish characteristic wetland hydroperiods via
backfilling or plugging of toe -slope ditches and connection to the down -gradient floodplain;
plant areas lacking characteristic wetland tree and shrubs

Section G. Technical Approach
A. Proposed Stream Mitigation
1. Cool Run
Stream restoration efforts are designed to restore a stable stream that approximates
hydrodynamics, stream geometry, and local microtopography relative to reference conditions. The
channel is incised (as evidenced by elevated bank height ratios approaching and exceeding 2.0),
channelized and significantly influenced by adjacent berms that were created when the Site was
modified in a regional drainage effort. It is evident that bankfull/channel forming and higher flows
rarely access the historic floodplain within the proposed restoration reach, causing increased stress
and subsequent erosion within the banks and increased drainage of groundwater from the adjacent
floodplain.
It is anticipated that Cool Run will be restored as a Priority I (PI) restoration where the bankfull
elevation matches the historic/abandoned floodplain. Sections of relic natural channel within the
floodplain will be located during topographical surveys and utilized in the restoration design to the
greatest extent practical. Priority II stream restoration techniques may be utilized in the upper and
lower reach of the Site tributaries to tie the channel into the existing ditches above and below the
Site. Priority II reaches will be minimized to the maximum extent feasible. Additionally, removal of
the extensive berm network that currently blocks flood access to the floodplain will allow above -
bank flows to access the entire valley.
The use of in -stream structures for grade control and habitat is essential for successful stream
restoration. It is anticipated in stream structures may be incorporated into the channel design in an
effort to increase in -stream foraging and propagation habitat, promote a diversity in bed form, and
provide immediate bank stability in higher stress areas. In -stream structures may be placed in the
channel to elevate local water surface profiles in the channel, potentially flattening the water
energy slope or gradient and directing stream energy into the center of the channel and away from
banks. The structures will consist of log cross -vanes or log j-hook vanes. In addition, the structures
will be placed in relatively straight reaches to provide secondary (perpendicular) flow cells during
bankfull events.
The mitigation plan will strive to minimize impacts to mature specimen trees within the valley of
Cool Run. It is anticipated that trees 12 inches and greater will be located during topographical
surveys in an effort to reduce impacts to mature vegetation during design and subsequent
construction. Any portion of the existing buffer that is removed to facilitate restoration of the
channel will be replanted with native vegetation characteristic of a Coastal Plain Bottomland
Hardwood Forest community (Schafale & Weakley 1990) (refer to proposed planting below).
2. UT-1
Headwater channel restoration is proposed for the valley of UT-1. UT-1 was historically
straightened and depended in an effort to promote rapid drainage through historic wetlands. The
proposed mitigation plan is anticipated to include the filling of existing ditched channels, installation
of valley sills using natural native materials, removal of berms through the valley, restoration of
natural contours, and restoration of natural vegetation that is adapted to headwater conditions.
Removal of the drainage effects of the ditched channels should greatly improve the storage and
filtering function of the headwater valley, provide attenuation for storm water flows from the
contributing watershed, provide semi -aquatic habitat for various fauna and flora, and provide a
significant carbon source for downstream receiving waters associated with Cool Run.
Response to Request for Proposal #16-20190201 14 1 P a g e
Section G. Technical Approach
3. General Description of Stream Mitigation Activities
It is anticipated that construction of the Site will begin at the upstream extents of the valleys on -site
and work downstream. Standard construction equipment including CAT 320 (or equivalent) track
hoes, dozers, and track trucks will be utilized to clean -out and re-establish the relict channel.
Erosion control measures such as a pump -around operation with silt bags, silt checks, erosion
control matting, seeding and mulch will be implemented during construction. Grading quantities
cannot be determined until after site design which will occur in the Mitigation Plan phase.
However, earthwork is anticipated to be relatively minimal since the bankfull channel of Cool Run
will be reconnected to the original floodplain for the majority of the restoration (i.e. Priority
restoration) and because UT-1 will be restored as a headwater channel through the valley.
The desired plant community and species types will be established by utilizing a reference forest
system, but may include species found within the existing wooded forest along the southern end of
the Site along Cool Run. Planting densities of bare root species at approximately 680 trees per acre
are anticipated for areas of restored vegetative buffer. Soil amendments may be added during and
following construction to promote grass and tree growth within the disturbed areas on -site. Signs
will be posted along the easement boundary to clearly demarcate the easement boundary for the
landowners.
4. Summary of Stream Function Uplift
It is anticipated that all mitigation activities will substantially increase net ecological, hydrologic and
hydraulic functions to Cool Run, and the headwater stream valley associated with UT 1, and
downstream receiving waters. Functional uplift is expected to include the following:
• Stabilizing stream channel side slopes and invert on Cool Run through reconnection to the
historic channel, coir fiber matting, and establishment of permanent native vegetation
(grasses and trees).
• Removal of eroding channel side slopes on UT's by filling channels and grading to natural
contours.
• Creating stable and productive in -stream habitat within Cool Run through a more natural
plan form geometry that promotes deeps and shallows throughout the channel.
• Introduction of woody materials into the channel of Cool Run such as toe wads and logs sills
that will provide refuge habitat for fish and semiaquatic species, foraging habitat for
macrobenthos, channel depth variability, stream shading, and invert stabilization.
• Installation of riparian and bank vegetation that will add woody debris to the channel for
foraging and refuge and will shade the channel which will regulate temperatures and
stabilize dissolved oxygen.
• Connecting higher than bankfull flows to its historic floodplain, which will decrease channel
shear stress, promote attenuation of water across the broad floodplain, drop and store
suspended solids on the floodplain, filter nutrients, pesticides and other pollutants, and
rehydrate the riparian buffer to allow for greater groundwater and surface water storage.
• Removal of the drainage effects of the ditched channels of UT-1 should greatly improve the
storage and filtering function of the headwater valley, provide attenuation for storm water
flow from the contributing watershed, provide semi -aquatic habitat for various fauna and
flora and provide a significant carbon source for downstream receiving waters associated
with Cool Run.

Section G. Technical Approach
5. Reference Streams
Stream reference reaches will be incorporated into the Natural Channel Design to assist in
determining morphological parameters for the restored channels. The design team has restored
numerous single thread and headwater streams within the same Ecoregion as the Site and have
previously identified and surveyed several suitable reference streams (both single thread and
headwater) that have been approved through agency coordination and used in Mitigation Plans. It
is anticipated that these previously surveyed and approved reference sites will be used to assist in
completion of the Site design.
B. Proposed Wetland Mitigation
Approximately 14.2 acres of former riparian wetland (or highly degraded wetland) associated with
the channelized tributaries have been targeted for restoration. As discussed in the previous
section, these areas have been historically drained through silvicultural and agricultural
management activities over the past five decades. The riparian restoration will occur within the
existing crenulation of the stream bottom via re-establishment of the original stream channel
geometry and bed elevation resulting the reconnection to the stream to adjacent riparian areas.
The reconnection of the stream and adjacent riparian wetlands (in concert with the removal of
other on -site ditches) will restore characteristic hydroperiods (via minimizing subsurface drainage
and increasing overbank flooding within the adjacent floodplain). The proposed restoration
footprint for these areas has been identified via contour LIDAR data, geomorphic data, and
observed field conditions. The final footprint will be premised on more detailed site investigations
and an approved wetland delineation (i.e. jurisdictional determination). Modeling of similarly -sized
stream reaches have demonstrated sufficient hydrologic inflow resulting from elevation of static
groundwater elevations and periodic overbank flooding in response to precipitation events.
Earthwork will include the backfilling of the existing, channelized segment of Cool Run and the re-
establishment of the relict Cool Run tributary. Existing spoil piles will be removed (i.e. will be
utilized to backfill ditches). In addition, the ditch located on the eastern toe of slope of the valley
will be plugged and/or backfilled to remove its drainage influence. Earthen material from side -cast
spoil will be used to backfill the adjacent ditches. Material will be consolidated to effectively
impede drainage. As a result, portions of the roadside ditches will remain as open water habitat
pending final cut/fill volumes. Clay plugs will be installed at prescribed intervals and will be
reinforced with filter -fabric and rip -rap to ensure long-term stability and functioning. Areas within
the valley that are graded will be disked, straw -mulched, and planted.
Prior to any grading work, appropriate federal and state authorizations will be obtained for
earthwork (including a Nationwide Permit 27). Erosion control measures to prevent sediment from
leaving the site will include installation of check dams within downgradient sections of ditches to be
backfilled and/or plugged. Areas to be graded will be stabilized with straw mulch and temporary
and permanent seeding. In addition, all graded areas will be planted with characteristic wetland
tree bare -root seedling and containerized wetland shrubs (per the planting plan in the final,
approved Mitigation Plan).
Response to Request for Proposal #16-20190201 16 1 P a g e
Section G. Technical Approach
The proposed restoration areas will be planted with species typical of a small stream swamp
community (Figure 9). Much of the restored riparian wetland valley will be re -planted due to the
lack of characteristic riparian wetland vegetation. As indicated above, much of the area consists of
non -target species characteristic of drained sites. Areas to be replanted will be drum -chopped and
or bush -hogged prior to planting. Areas with existing, suitable canopy species (at the southern
terminus of the site) will be left intact with larger specimen trees of target species located and
preserved. Plantings of the riparian valley will include installation of bare -root seedlings of bald
cypress (Taxodium distichum), swamp tupelo (Nyssa biflora), ironwood (Carpinus caroliniana), and
swamp chestnut oak. It is expected that other characteristic species will recruit naturally into these
restored areas upon successful hydrologic restoration.
C. All Mitigation
It is anticipated that Priority I restoration will be utilized throughout Cool Run to the maximum
extent practical. Several in -stream woody structures such as densely vegetated soil lifts, toe wood,
log sills, and cover logs are anticipated to be incorporated into the channel design. The final
bankfull channel size will be determined during the Mitigation Plan; however, preliminary data
suggests that the channel will be designed as moderately low width -to -depth ratio C or E type
channel that conveys the bankfull discharge. Additionally, the contributing UT-1 will be restored as
headwater streams within the Site. It is anticipated that UT-1's existing channel will be filled, and
the valleys graded to natural contours that mimic pre -disturbance conditions.
1. Site Planting
The majority of the hardwood riparian buffer has been removed from the Site, with portions of
buffers, primarily on the UT-1, being comprised of agricultural field. The proposed buffer width
includes a minimum of the required 50 foot stream buffer; however, the proposed buffer will
extend out to 100 ft or greater. It is anticipated that trees 12 inches and greater will be surveyed
within the restoration area in an effort to ensure protection of mature vegetation during design and
subsequent construction. Portions of the existing buffer that are removed to facilitate restoration of
the channels will be replanted with native vegetation.
The proposed mitigation site will provide for the establishment of natural plant assemblages
occurring within riparian habitats of the Coastal Plain. Target species to be planted have been
identified based upon site -specific information (including soil profiles and evaluation of landscape
position). The proposed planting regime will result in a mature community characteristic of specific
wetland community types. Establishment of a characteristic plant community will provide for the
necessary structure for resident and migratory fauna utilizing these types of habitat. The project is
expected to benefit a range of fauna by providing for a contiguous habitat corridor suitable for
refuge, nesting, and feeding. In addition, project activities are expected to contribute to enhanced
water quality conditions beneficially affecting downstream faunal communities.
The final planting plan will be premised on a comprehensive vegetation survey of adjacent wooded
areas as well as site soils and hydrology such that selected native trees will be well -suited to the
site -specific conditions of the property to promote high survivorship rates. No existing exotic or
invasive species have been observed within the project area. However, the mitigation plan will also
incorporate an invasive species management plan and protocol that can be implemented should
invasive species volunteer into the site. Note that the graded areas will also be planted with bare -
root seedlings, and live stakes of appropriate species (black willow, silky dogwood, and/or
Response to Request for Proposal #16-20190201 17 1 P a g e
Section G. Technical Approach
elderberry) will be installed. Planting densities of bare root species at approximately 538 to 680
trees per acre are anticipated for the restored vegetative buffer, but may be lower in areas that
may only require supplemental plantings. Soil amendments may be added during and following
construction to promote grass and tree growth within the disturbed areas on -site.
Species selection and distribution will be matched closely to micro -site hydrologic and edaphic
conditions. In other words, species more tolerant of poorly drained soils (e.g. bald cypress) will be
planted within lower landscape positions generally consisting of the Muckalee soil series while
species characteristically occurring in better drained soils will be planted in slightly higher convex
landscape positions.
2. Stream Crossings
There are currently no stream crossings within the Site.
3. Easement Boundary Protection
Marking of the easement boundary will be provided in the form of signage which will demarcate
the bounds of the conservation easement.
D. Mitigation Quantities
This proposal details one Mitigation Option that is summarized in Table 6 below. Note that the
table reflects stream credit and riparian wetland credit projections in excess of the requested
amounts in the RFP. While the project team anticipates overage on credits for these mitigation
types, it is understood that the contracted amount will not exceed the requested quantities (2,000
stream credits, 8.0 riparian wetland credits). The proposed project will satisfy all the credit needs
identified in the RFP.

G. Success Criteria
Upon completion of the restoration project, a Baseline Monitoring Report will be prepared and
submitted to the NC DMS to document the extent of the mitigation performed. The report will
include all information required by DMS monitoring guidelines including photographs, plot
locations, and documentation of existing species density and composition.
The performance standards shall be consistent with the requirements described in the Federal rule
for compensatory mitigation project sites as described in the Federal Register Title 33 Navigation
and Navigable Waters Volume 3 Chapter 2 Section § 332.5 paragraphs (a) and (b). Additionally, the
October 24`", 2016 "Notification of Issuance of Guidance for Compensatory Stream and Wetland
Mitigation Conducted for Wilmington District" will be used to not only to determine monitoring
requirements but also success criteria. Criteria below are preliminary conceptual success criteria
and may change upon approval of the final mitigation plan.
Response to Request for Proposal #16-20190201 19 1 P a g e
Section G. Technical Approach
1. Streams
The restored stream reaches are proposed to be monitored for geomorphic activity. Annual
fall/winter monitoring will include development of channel cross -sections on riffles in addition to
visual observation of channel stability. A longitudinal profile of the thalweg, water surface, bankfull,
and top of bank will be collected during the as -built survey of the constructed channel.
a. Stream Dimension
General maintenance of a stable cross-section and hydrologic access to the floodplain features over
the course of the monitoring period will generally represent success in dimensional stability. Some
changes in dimension (such as lowering of bankfull width -to -depth ratio) should be expected. Riffle
sections should generally maintain a Bank Height ratio approaching 1.0 —1.2, with some variation in
this ratio naturally occurring, and display an entrenchment ratio of no less than 2.2. Both ratios
should display no more than 10 percent change from year-to-year. Pool sections naturally adjust
based on recent flows and time between flows; therefore, more leeway on pool section geometry is
expected.
b. Stream Pattern and Profile
Pattern features should show little adjustment over the standard 7 year monitoring period. The
profile should not demonstrate significant trends towards degradation or aggradation over a
significant portion of a reach.
c. Substrate and Sediment Transport
There should be an absence of any significant trend in the aggradational or depositional potential of
the channel.
d. Hydraulics
All stream channels will maintain an ordinary high water mark (OHWM) through monitoring. A
minimum of four bankfull events must be documented within the 7 year monitoring period. The
four bankfull events shall occur within separate years.
e. Headwater Stream Restoration
Headwater stream restoration success criteria is anticipated to include documentation of surface
water flow for a minimum of 30 days during the monitoring timeframe. It is anticipated that
monitoring years 1 through 4 will document concentrated flow within the restored headwater
valley. Additionally, monitoring years 5 through 7 will document both evidence of concentrated
flow and the development of a stream bed and bank (i.e. Ordinary High Water Mark).
f. Macroinvertebrate and Water Quality
The provider will coordinate with resource agencies to determine if site specific monitoring
protocols and success criteria for the Site are required.
2. Wetland Hydrology
Hydroperiods of restored wetlands will be established in the Mitigation Plan and will be consistent
with the Wetland Threshold Saturation ranges identified in the Wilmington District Stream and
Wetland Compensatory Mitigation Guidance (October 2016). Groundwater and shallow surface
water elevations will be collected daily during the growing season via automated gauges and
downloaded quarterly. The project team will prepare hydrographs depicting water levels
Response to Request for Proposal #16-20190201 20 1 P a g e
Section G. Technical Approach
throughout the growing season of each monitoring year. Should wetland hydrology fail to meet
success criteria as outlined in the Mitigation Plan for the Site, LMG will evaluate the potential
causes of failure and provide DMS with their remediation proposal. The remediation proposal will
detail corrective actions and/or maintenance actions proposed and an implementation schedule.
Upon review and approval of the remediation proposal by DMS, LMG will implement the necessary
corrective measures.
3. Vegetation
Vegetation plots will be monitoring for 7 years, with monitoring events occurring on years 1, 2, 3, 5,
and 7. A combination of permanent fixed plots and random plots will be employed to document
vegetation coverage. The specific protocol for plot establishment will be consistent with the recent
(October 2016) Wilmington District IRT Guidance. The performance standards require a minimum
of 320 planted stems per acre surviving after year three, 260 stems per acre after year five, and 210
stems per acre after year seven. Trees should average 7 feet in height at year five and 10 feet in
height at year seven. In addition, any single species can only account for up to 50% of the required
number of stems within a vegetation plot. Should the performance criteria outlined above not be
met during the monitoring period, a remedial action plan will be prepared that will identify
corrective actions and/or maintenance actions proposed and an implementation schedule for said
actions. Upon review and approval by DMS, such actions will be implemented.
4. Noxious Species
Noxious species will be identified and controlled so that none become dominant or alter the desired
community structure of the proposed Site. If noxious plants are identified as a problem in the
proposed Site, a species -specific control plan will be prepared and provided to DMS for approval
prior to implementation. All vegetation removal from the Site shall be done by mechanical means
only, unless DMS has first authorized the use of herbicides or algaecides for the control of plants in
or immediately adjacent to the affected areas.
5. Success Criteria Methodologies and Reporting
Monitoring of the Site will be performed until success criteria are met as defined in the restoration
plans and the permits. Results will be documented on an annual basis, with the associated reports
submitted to DMS as evidence that goals are being achieved. The project team and DMS, in
coordination with the appropriate regulatory agencies, will determine when the performance
standards have been achieved at the Site. If standards are not met, project team will perform
appropriate remedial activities to satisfy DMS. If the monitoring of the Site demonstrates that the
Site is successful by year five and no concerns have been identified, the project team will propose to
terminate monitoring of the Site and forego the monitoring requirements of years six and seven. In
general, the restoration success criteria, and required remediation actions, are based on the
Wilmington District Stream and Wetland Compensatory Mitigation Update (USACE et al. 2016) and
the Annual Monitoring Report Format, Data Requirements, and Content Guidance (NCDMS 2017).
6. Frequency
All monitoring reports will be submitted to DMS's designated representative for coordination with
the appropriate regulatory agencies by December 1st of each year. The year of construction may
have two submittals, one being the As -Built drawings and the second being the First Year Annual
Monitoring Report. If monitoring reports indicate any deficiencies in achieving the success criteria
on schedule, a remedial action plan will be included in the annual monitoring reports. The project
Response to Request for Proposal #16-20190201 21 I P a g e
Section G. Technical Approach
team will be available to coordinate any agency site visits; both before and after restoration
activities have been completed. Vegetative monitoring will be conducted between July 15t and leaf
drop of each monitoring year.
H. Quality Control
Our quality approach is based on the Total Quality Management philosophy, which provides
guidance on producing quality deliverables. Quality assurance begins with a clear understanding of
the goals and objectives of the project prior to finalizing project scoping. Project team members are
selected based upon qualifications considered most suitable for accomplishing identified task items.
The Project Manager (PM) is responsible for establishing clear roles for team members, facilitating
project schedules, and ensuring quality. The project team members are involved in the
development and refinement of the final scope of work and project schedule.
Quality control will be ensured for editorial content, technical validity, and overall project
effectiveness. Prior to submittal of any documents, the identified quality assurance reviewer meets
with the PM and reviews the document's technical merits and accuracy. The assignment of a
Technical Reviewer is made by the PM. The Technical Reviewer is a senior level scientist whose
background and experience avoids and minimizes issues that may have been encountered on prior
projects. In addition, a peer reviewer will provide editorial comment to ensure correct spelling,
grammar, formatting, and consistency in text and graphics.
The project team has a strong record in providing deliverables in a timely fashion to our clients and
the regulatory community. Projects are typically executed within the stated budgetary constraints.
The assembled team has demonstrated ability to maintain efficiency while limiting cost overruns
and providing our client with a quality product. LMG has provided deliverables to NCDEQ (NC DMS)
on time and on -budget throughout the course of our work over the past 15 years.
Representative QA/QC measures to be employed for the Cool Run Mitigation Site are described
further below.
1. The Project Manager (Mr. Kevin Yates) will be responsible for ensuring timely submittal of
project deliverables (e.g. mitigation plan, baseline monitoring document, monitoring report,
etc.) and invoicing that accurately reflects contract tasks and contract percentages. In
addition, CMS has direct experience in NC DMS invoicing procedures. CMS will manage the
invoicing spreadsheet that will display percentage of task completed and invoiced along
with cumulative invoice totals.
2. The Technical Reviewer (Mr. Christian Preziosi) and the Peer Reviewer (Ms. Kim Williams)
will be responsible for the technical and editorial content of the project deliverables and will
ensure that the deliverables are consistent with current NC DMS standards and templates,
including the Annual Monitoring Report Template (ver. 2.0)). All mitigation work will be
performed in accordance with the Wilmington District Stream and Wetland Compensatory
Mitigation Update (USACE et al. 2016).
3. Task managers will be assigned for each of the major milestones of the project. Task
managers will provide a minimum of monthly progress reports to the Project Manager. The
Response to Request for Proposal #16-20190201 22 1 P a g e
Section G. Technical Approach
Project Manager will assign deadlines for all tasks and sub -tasks and will maintain a gantt
chart illustrating projected completion dates and percentages of tasks completed.
4. The construction management team led by Mr. Grant Lewis of AXE and Wes Fryar of LMG
will work closely with the Project Manager for the selection and oversight of the contractor
and for the procurement of native hardwoods suitable for site conditions. LMG and AXE will
conduct a pre -construction meeting with the contractor and planting foreman to review the
plans and to discuss specific construction and planting protocols. Professional scientists
from LMG and AXE will be on -site during planting and construction to ensure
implementation consistent with the approved mitigation plan. Planting and construction
will be photo -documented. The construction management team will work closely with the
monitoring task manager for the installation of permanent vegetation monitoring plots and
the baseline monitoring.
5. Monitoring reports will be submitted annually to the NC DMS (by December 1 of each year).
These reports will include results of vegetative monitoring and photographic documentation
of site conditions. Monitoring reports will also identify any contingency measures that may
need to be employed to remedy any site deficiencies. The seventh year monitoring report
will include a close-out report that provides an assessment of the monitoring data collected
from the entire monitoring period. The Project Manager and the monitoring task manager
will attend the close-out meeting(s) and will present the final project to the IRT following all
DMS closeout procedures and templates.
