Middle South Muddy Creek Restoration NCEEP Mitigation Plan

EXECUTIVE SUMMARY
The North Carolina Ecosystem Enhancement Program (EEP) proposes to restore, enhance, and
preserve reaches of South Muddy Creek and two of its tributaries at two sites located in southeastern
McDowell County. This Mitigation Plan describes the details, methods, and monitoring protocols
proposed to generate approximately 3,281 stream mitigation credits, which includes approximately
1,990 linear feet of stream restoration, approximately 196 linear feet of stream enhancement and
approximately 6,836 linear feet of preservation.
General Site Conditions
The Middle South Muddy Creek Site (the Site) occurs near the intersection of Brackett Town Road and
Sprouse Road in southeastern McDowell County. The Site encompasses approximately 5.87 acres of
predominately agricultural land. Within the Site, approximately 2,201 linear feet of channel exhibit
mitigation potential. Agricultural practices including cattle grazing, maintenance and removal of
vegetation, and relocating, dredging, and straightening of on -site streams have contributed to the
degraded water quality and unstable channel characteristics.
Included as a part of this project is the Haney Preservation Tract, which is located just north of the Middle
South Muddy Creek Site along Vein Mountain Road. This tract preserves 5,836 LF of stream and
approximately 35 acres of buffer along South Muddy Creek.
The Middle South Muddy Creek Site and the Haney Preservation Tract were both identified as part of a
Local Watershed Planning (LWP) initiative conducted by the Muddy Creek Restoration Partnership and
covering the entire Muddy Creek Watershed, which culminated in development of a Feasibility Report &
Restoration Plan in late 2003. An updated and expanded project atlas for the Muddy Creek LWP area
was completed using EEP funding in 2008. This LWP meets criteria for CFR- compliant watershed
assessment and planning to support mitigation requirements under the Clean Water Act.
Restoration Concept
Restoration and enhancement practices proposed for this project have been designed with the intent to
minimize unnecessary disturbance to adjacent land. Professional judgment has been used to determine
which channel reaches could potentially benefit most from preservation or enhancement over full
restoration. Where restoration was determined to be warranted, consideration was given to which
reaches could best be served by maintaining as much of the existing channel pattern as possible.
Proposed South Muddy Creek is designed as a Type C4 stream. This channel configuration provides a
stable and natural form in the Type VIII(b) alluvial valley in which the existing stream is found. Proposed
Sprouse Branch and Iva Branch are designed as Type B5 streams. These channel configurations
provide the most stable and natural form for these slightly entrenched channels flowing through
moderately sloped colluvial valleys. The proposed channel dimensions, patterns, and profiles are based
on hydraulic relationships and morphologic dimensionless ratios of the reference reaches.
The installation of brush, rock, and wood structures will be utilized throughout the restored reaches of the
Site. Brush toe structures will be installed along the toe of bank to provide roughness and bank stability
on outer meander bends. Boulder structures will be used for grade control to prevent headcut formation.
Log vanes with rootwads will be installed in meander bends to direct the flow away from the outside of the
bend and provide toe and bank protection. On -site material including brush, boulders, logs, and bed
material will be used to the maximum extent possible and in- stream structures will be designed to improve
aquatic habitat.
This mitigation plan has been written in conformance with the requirements of the following:
Federal rule for compensatory
Register Title 33 Navigation and
paragraphs (c)(2) through (c)(14).

1.0 RESTORATION PROJECT GOALS AND OBJECTIVES
The Middle South Muddy Creek Project (the Site) is located in the Muddy Creek Local Watershed
planning area (http: / /www.nceep.net /services /Iwps /muddy creek/Muddy Creek plan 2003.pdfl. The
Project Site watershed includes Hydrologic Unit Code (HUC) 03050101040020 which was identified as a
Targeted Local Watershed (TLW) in EEP's 2009 Upper Catawba River Basin Restoration Priority (RBRP)
Plans ( http:// www .nceep.net/services /restplans /Upper Catawba RBRP 2009.pdfl.
The Muddy Creek Restoration Partnership (MCRP) developed a local watershed plan (LWP) for the 111
sq mi drainage area that included land use analysis, water quality monitoring and stakeholder input to
identify problems with water quality, habitat and hydrology. The Muddy Creek watershed is characterized
as primarily agricultural and has a history of entrenchment and increased sediment problems due to
barren bank issues. MCRP completed the Feasibility Report and Restoration Plan for the Muddy Creek
Watershed in December 2003
(http: / /www.nceep.net/services /Iwps /muddy creek /Muddy Creek plan 2003.pdfl.
The Muddy Creek LWP identified nutrients, streambank erosion and livestock access to streams as major
stressors within this watershed. The LWP Feasibility Report (2003) included an initial set of project site
recommendations, including identification of the Middle South Muddy Creek Project as a stream
restoration and enhancement opportunity with the potential to improve water quality and habitat within the
Muddy Creek watershed. The Muddy Creek Mitigation Search Final Summary Report (2008), which was
prepared to address the plans and objectives of the MCRP, additionally identified the Haney Tract as a
mitigation opportunity.
The goals of the Middle South Muddy Creek Project address stressors identified in the LWP and include
the following:
The following goals are established to guide the restoration process for the project:
1.) Improve local water quality within the restored channel reaches as well as the downstream
watercourses through: (a) the reduction of current channel sediment loads by restoring
appropriately sized channels with stable beds and banks, (b) the reduction of nutrient loads from
adjacent agricultural fields with a restored riparian buffer, and (c) the reduction of water
temperatures provided through shading of the channel by canopy species along with the resultant
increase in oxygen content.
2.) Improve local aquatic and terrestrial habitat and diversity within the restored channels and their
vicinity through: (a) the restoration of appropriate bed form to provide habitat for fish, amphibian,
and benthic species, (b) the restoration of a suitable riparian buffer corridor in order to provide
both vertical and horizontal structure and connectivity with adjacent upland areas, and (c) the
restoration of understory and canopy species in order to provide forage, cover, and nesting for a
variety of mammals, reptiles, and avian species.
3.) Preclude land disturbing activities including the construction of additional infrastructure, future
mining activities and agricultural practices including cattle grazing and the application of
pesticides and fertilizer within the riparian buffer area by providing a permanent conservation
easement.
The following objectives are proposed for accomplishing the above listed goals:
1.) Provide approximately 3,281 stream mitigation units (SMU's) through Priority I and II
restoration of approximately 1,990 linear feet of stream, enhancement of approximately 196 linear
feet of stream, and preservation of approximately 6,836 linear feet of stream threatened by
mining activities.
2.) Restore natural stable channel morphology and proper sediment transport capacity.
3.) Create and /or improve bed form diversity and improve aquatic and benthic macroinvertebrate
habitat.
4.) Construct a floodplain bench that is accessible at the proposed bankfull discharge.
5.) Improve channel and stream bank stabilization by integrating in- stream structures and native
bank vegetation.
Middle South Muddy Creek Restoration NCEEP Mitigation Plan

6.) Provide approximately 5.87 acres of riparian buffer restoration by establishing a native forested
and herbaceous riparian buffer plant community with a minimum width of 30 feet from the edge of
the restored channels. This new community will be established in conjunction with the
eradication of any existing exotic and /or undesirable plant species.
7.) Construct barricades on existing dirt road network on Haney Tract to prevent future vehicular
trespassing.

entrance to the Site is on the left at Sprouse Rd. and is located at a Lat/Long of 35.5635° N and 81.9249°
W.
2.2 Site Selection
2.2.1 Description
The Site encompasses approximately 5.87 acres of predominately agricultural and forested land and
includes approximately 2,513 linear feet of degraded channel proposed for restoration and enhancement.
Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Livestock have
unrestricted access to the majority of Site streams, resulting in significant local disturbance to stream
banks. Additional land use practices, including the maintenance and removal of riparian vegetation, and
the relocating, dredging, and straightening of on -site streams have contributed to the degraded water
quality and unstable channel characteristics.
2.2.2 USGS Hydrologic Unit Code and NCDWQ River Basin Designations
The Site is located in the Catawba River Basin, United States Geological Survey (USGS) 14 -digit
Hydrologic Unit 03050101040020, within the North Carolina Division of Water Quality (DWQ) sub basin
03- 08 -30. The Site lies within a NC EEP Targeted Local Watershed and is part of a Local Watershed
Plan. Site tributaries are not listed on the NCDWQ final 2010 303(d) lists (NCDWQ 2010). South Muddy
Creek drains to Muddy Creek approximately 12.5 miles downstream of the Site which in turn drains into
the Catawba River another 4.5 miles downstream. South Muddy Creek has been assigned the Stream
Index Number 11 -32 -2 by DWQ.
2.2.3 Watershed Characterization
The Site watershed is characteristic of the Foothills region with moderate rainfall and moderate valley
slopes (5% to 20 %). Annual precipitation within McDowell County averages 56.1 inches and elevations
within the Site range from 1,315 ft. on upper slopes above Sprouse Branch to 1,263 ft. at the site outfall
(NGVD). The Site encompasses approximately 2,513 linear feet of streams including South Muddy
Creek and two tributaries, named for the purposes of this project as Sprouse Branch and Iva Branch.
The drainage area of South Muddy Creek is 4.52 miZ (2,893 ac) at the upstream project limits and 4.69
miZ (3,002 ac) at the downstream limits. The headwaters of both Sprouse Branch and Iva Branch are
located within the project extents, and the drainage areas at their confluences with South Muddy Creek
are 0.042 miZ and 0.046 miZ, respectively.
2.2.4 Surface Water Classification
According to the North Carolina Department of Environment and Natural Resources (NCDENR), Division
of Water Quality (DWQ) website, South Muddy Creek has been assigned a Best Usage Classification of
C. The section of the Catawba River that South Muddy Creek and the project tributaries drain to has
been assigned the Best Usage Classification of WS -IV; Tr. Class C waters are suitable for aquatic life
propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The designation Tr
(Trout Waters) includes areas protected for natural trout propagation and survival of stocked trout. The
designation WS -IV (Water Supply IV) indicates waters used as sources of water supply for drinking,
culinary or food processing purposes where a WS -1, II or III classification is not feasible. These waters are
also protected for Class C uses. WS -IV waters are generally in moderately to highly developed
watersheds or Protected Areas.
Middle South Muddy Creek Restoration NCEEP Mitigation Plan

2.2.5 Physiography, Geology, and Soils
The Site is located in the Eastern Blue Ridge Foothills ecoregion of North Carolina. Regional
physiography is characterized by open, low mountains at a lower elevation than most Blue Ridge regions
having more Piedmont influences. This region includes the Brushy Mountains to the north and the South
Mountains to the south. Covered with mixed oak and oak - hickory-pine forests, these mountains tend to
be slightly drier and warmer than most of the Blue Ridge ecoregion. The underlying geology within the
ecoregion consists of primarily metamorphic rocks with occasional igneous and sedimentary deposits.
The local lithology is mapped as migmatitic granitic gneiss.
The valley associated with the portion of South Muddy Creek within the project extents is a narrow alluvial
valley, Type VIII(b) (Rosgen) with cross - slopes ranging from 1% to 3% and a longitudinal slope
approximately 0.4 %. The valleys of Sprouse Branch and Iva Branch are moderately sloped Type II
(Rosgen) colluvial valleys with a down valley gradient of 2% to 5% that transition onto the gentle alluvial
valley of South Muddy Creek.
The Site lies in the low mountains of North Carolina in rolling topography underlain by metamorphic and
igneous bedrock. The side slopes in the area are well drained, moderately permeable, sandy -loamy sub-
soils (Hayesville -Evard Soil Series). The alluvial soils along the stream systems in the area are generally
underlain by yellowish- brown, sandy -loamy sub -soils belonging to the lotla series. These somewhat
poorly drained soils are moderately permeable and are non - hydric.
2.2.6 Historical Land Use and Development Trends
The watershed upstream of the Site is characterized mainly by agricultural and forested land with
moderate to heavy mineral mining activity occurring in close proximity to tributaries. Mining activities
appear to be non - commercial individual prospecting for gold. Most of these activities appear to have
occurred in the floodplain, however there is evidence of some incursion into the stream channels.
Residential land use accounts for only a marginal percentage of the watershed. Currently rural residential
land use makes up approximately 3 percent of the watershed and impervious area covers less than 1
percent of the total watershed. Historical land use was evaluated through conducting interviews of
property owners and reviewing aerial photos from 1954 through 2010 (ERTR, June 2011). Historical land
use has been consistent with present land use practices that include pastureland for cattle, hay
production, and some forest stands. Grazing livestock have historically had access to most on -site stream
reaches and the adjacent terraces.
2.2.7 Existing Site Conditions
South Muddy Creek
Based on the present configuration of the channel and on typical historical agricultural practices it is likely
that South Muddy Creek was realigned and dredged throughout the project reach. The resulting channel
form exhibits low sinuosity and moderate incision. The channel classifies as a Type G4 stream under the
Rosgen channel classification system throughout the majority of the on -site reach. The existing
entrenchment ratios range from 1.2 — 2.6, bank - height ratios range from 1.8 — 2.5, and the width /depth
ratio is 3.3 — 9.6. The high bank - height ratios and low width /depth ratios result in increasing the stress on
the stream banks. The profile appears vertically stable due to the low channel gradient, although the
riffle -pool form is poorly developed and often misaligned with the pattern, further contributing to near -bank
stress. Mobile bed material consists mainly of gravel (38 % -65 %) with lesser constituents of cobble (19 %-
24%) and a considerable fraction of sand (16 % -37 %).
South Muddy Creek was divided into two vegetative community types due to the presence of livestock
below the culvert. The upper reach is characterized as agricultural pastureland and is utilized primarily for
hay production with the dominant grass being fescue (Festuca sp.). The riparian buffer, adjacent to the
agricultural field, is only 5 to 10 feet wide and is dominated by tag alder (Alnus serrulata), red maple (Acer
rubrum) and river birch (Betula nigra). The existing riparian buffer consists of less than 5% invasive
exotics including Japanese honeysuckle (Lonicera japonica) and Chinese privet (Ligustrum sinense).
The lower reach is also characterized as agricultural pastureland, but it is primarily used for livestock
production. The riparian buffer is 0 to 5 feet and is dominated by tag alder, red maple, tulip poplar
(Liriodendron tulipifera), and river birch. There were no significant invasive exotics populations observed
in this reach.
Middle South Muddy Creek Restoration NCEEP Mitigation Plan

Sprouse Branch
Sprouse Branch originates from a spring within a forested reach at the upstream project extents. The toe -
of -slope spring, which forms a small channel within a confined valley, is impacted by livestock and
erosion. At the termination of the forested reach, Sprouse Branch continues as a dredged and
straightened ditch. Entrenchment ratios are generally low; between 1.1 and 1.9. Width /depth ratios are
moderate at the upstream end and low at the downstream end; 11 — 13 and 6 — 7, respectively. The
channel classifies as a Type G5 stream. Bed material is composed mainly of sand with only a small
fraction of gravel ( <10 %). The gravel present in the channel is in the fine gravel class (4 -8 mm).
The upper reach ( -200') of Sprouse Branch is dominated by red maple, black cherry (Prunus serotina),
and tulip poplar. The lower reach is agricultural pastureland dominated by fescue with tag alder present
along the ditch banks. Less than 5% of the riparian buffer contained invasive exotics including multiflora
rose (Rosa multiflora), Japanese honeysuckle and Chinese privet.
Iva Branch
Iva Branch originates within a drawline that drains a small catchment at the northeast project extents. The
channel remains vertically unstable as multiple headcuts have formed and migrated upstream to form a
deeply entrenched channel with steep, vertical bluffs. Unrestricted livestock access continues to
exacerbate instability. Entrenchment ratios range between 1.1 and 1.4. Banks are up to eight (8) feet high
at the upstream end of the channel and decrease to four (4) feet near the downstream end. The channel
bed slope ranges from 3% to 5% and the typical valley slope is 3.5 %. The channel classifies as a Type
G5 stream as bed material is composed mainly of sand (79 %) with small gravel (19 %) accumulating
towards the downstream end.
Iva Branch has a 5 to 15 foot riparian buffer comprised of red maple, river birch, American sycamore
(Platanus occidentalis), and black cherry. The surrounding pastureland is dominated by fescue. Other
species observed within the riparian zone include American holly (Ilex opaca), shortleaf pine (Pinus
echinata), black walnut (Juglans nigra) and red cedar (Juniperus virginiana). Iva Branch contained the
largest amount of invasive exotics (15 %). Invasives observed included multiflora rose, Chinese privet,
and Japanese honeysuckle.
Haney Tract
The Haney Tract is located approximately 1,000 feet downstream of the Middle South Muddy Creek Site.
This tract was identified as a target for preservation in the 2008 Muddy Creek Mitigation Search Final
Summary Report (September 2008). This tract has since been acquired for preservation and will preserve
5,836 LF of stream channel and approximately 35 acres of riparian buffer.
Historically the property has been the location of continuous mining for at least 50 years. Mining
operations may have been commercial at one time, but recently consisted of a club of individual
prospectors mining for gold lag deposits in the floodplain. Establishment of the conservation easement
will protect the stream and adjacent floodplain from future destructive mining activities.

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

6.1 Initial Allocation of Released Credits
The initial allocation of released credits, as specified in the mitigation plan can be released by the NCEEP
without prior written approval of the DE upon satisfactory completion of the following activities:
a. Approval of the final Mitigation Plan
b. Recordation of the preservation mechanism, as well as a title opinion acceptable to the USACE
covering the property
c. Completion of project construction (the initial physical and biological improvements to the
mitigation site) pursuant to the mitigation plan; Per the NCEEP Instrument, construction means
that a mitigation site has been constructed in its entirety, to include planting, and an as -built
report has been produced. As -built reports must be sealed by an engineer prior to project
closeout, if appropriate but not prior to the initial allocation of released credits.
d. Receipt of necessary DA permit authorization or written DA approval for projects where DA permit
issuance is not required.
6.2 Subsequent Credit Releases
All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a
determination that required performance standards have been achieved. For stream projects a reserve of
15% of a site's total stream credits shall be released after two bank -full events have occurred, in separate
years, provided the channel is stable and all other performance standards are met. In the event that less
than two bank -full events occur during the monitoring period, release of these reserve credits shall be at
the discretion of the IRT. As projects approach milestones associated with credit release, the NCEEP will
submit a request for credit release to the DE along with documentation substantiating achievement of
criteria required for release to occur. This documentation will be included with the annual monitoring
report.

7.0 MITIGATION WORK PLAN
7.1 Description of Target Stream and Vegetation Communities
Reference reaches were sought to provide a target for design of the proposed streams. Searches were
conducted first upstream and downstream of the Site and then into surrounding watersheds to find
suitable references that contained comparable slope, bed material, and valley type. A Type C4 reference
was located on Toms Creek, a tributary of the Catawba River in McDowell County and a Type B4
reference was located on Cold Springs Creek, a tributary to the Pigeon River in Haywood County. The
reference vegetation community data were collected at the Toms Creek reference site.
7.1.1 Reference Reach
The reference reaches were selected to represent the probable configurations for the proposed stream
restoration. Detailed geomorphic survey and Level II Rosgen classification were conducted on each
reference reach (See Appendix C).
Toms Creek Reference
The Toms Creek reference reach is located in the Blue Ridge hydrophysiographic region of North
Carolina. The watershed for Toms Creek reference is similar to the character of the South Muddy Creek
watershed including average annual rainfall, elevation changes, and valley type. The reference
watershed is located northwest of the project site within Pisgah National Forest and is predominantly
forested. The drainage area for the Toms Creek reference is 3.33 miZ.
The Toms Creek reach is representative of a C4 channel in a moderately sloped valley. Bed material,
channel slope, and valley form of this stream are consistent with the Site and provide reasonable
analogues for the potential channel forms that can be expected at the Site. The Toms Creek reference
reach has a D50 of 31 mm, D84 of 71 mm, channel slope of 0.93 % and width /depth ratio of 15.
Cold Springs Reference
The Cold Springs Creek reference reach is located in the Blue Ridge hydrophysiographic region of North
Carolina. The watershed is similar in many ways to the character of the Site watershed including average
annual rainfall, elevation changes, and valley type. However, the two tributaries on the project site are
sand bed streams with moderate gradient valleys (2 % -5 %) and a similar stream in reference condition
was not identified. The Cold Springs Creek reference represents a stable stream type with a gravel bed in
a similar valley type and slope. The reference watershed is rural and consists predominantly of forest
stands with some grassy fields although there are no livestock on the adjacent land. The drainage area
for the Cold Springs Creek reference is 2.77 miZ.
The Cold Springs reach is representative of a B4 channel in a moderately sloped valley with a narrow,
constrained floodplain. Channel slope, and valley form of this stream are consistent with the project site
and provide reasonable analogues for the potential channel forms that can be expected at the Site. The
Cold Springs reference reach has a D50 of 45mm, D84 of 130mm, channel slope of 0.024 ft/ft, and
width /depth ratio of 16.
Discharge and Bankfull Verification
Bankfull was readily identified on the reference streams as they exhibited consistent indicators throughout
the reach. Verification of bankfull was accomplished by plotting the bankfull cross sectional area against
the regional curve data. The graph indicates that the bankfull identified in the surveyed reach is
consistent with the regional curve data.
After verification of bankfull cross sectional area, bankfull discharge was calculated for the surveyed
reach using a single- section analysis. Manning's `n' was estimated from relative roughness calculations
of the bed material and from observation of the channel flow conditions. Water surface slope was
assumed to be consistent with the slope of the bed profile. Discharge was then plotted against a graph of
the regional curve data. The graphing of this data indicated that the calculated bankfull discharges were
consistent with the regional curve data.
Middle South Muddy Creek Restoration NCEEP Mitigation Plan 25

Channel Stability Assessment
A detailed channel stability assessment was not performed for these reaches since the bank and bed
stability were obvious from observation. Subsequent review of the surveyed dimensions confirmed that
width -depth ratios and bank height ratios were within the appropriate range for stable, self- maintaining
streams. Additional observations included significant upstream and downstream reconnaissance to
identify any past, present, or future signs or sources of degradation.
Limited Reach Reference
Through the course of conducting the reference reach searches, several streams were identified as
possessing qualities of stability and natural form. However, these reaches were determined not to be
suitable references for the project due to either incompatible stream type, valley form, or insufficient reach
length. In these locations morphological measurements were taken to supplement the data acquired from
the reference reach sites. Measurements on eight (8) individual reaches included bankfull width, bed
width, depth of bankfull, toe depth, and width of thalweg. A graph of this data is included in Appendix C.
7.1.2 Reference Vegetation Community
The plant community survey was performed at Toms Creek on July 6, 2011. The riparian plant
community most closely resembles a Montane Alluvial Forest as described by Schafale and Weakley
(1990). Canopy species observed included Sycamore (Platanus occidentalis), Green Ash (Fraxinus
pennsylvanica), American Beech (Fagus grandifolia), River Birch (Betula nigra), White Oak (Quercus
albs), Black Oak (Quercus velutina), Red Maple (Acer rubrum), and Tulip Poplar (Liriodendron tulipifera).
Subcanopy species included Spicebush (Lindera benzoin), American holly (Ilex opaca), iron wood
(Carpinus caroliniana), and witch hazel (Hamamelis virginiana). Herbaceous species included Christmas
Fern (Polystichum acrostichoides), Dog Hobble (Leucothoe fontanesiana), New York Fern (Thelyptris
novaboracensis), Virginia Creeper (Parthenocissus quinquefolia), and Yellowroot (Xonthorhiza
simplicissima).
7.2 Narrative of Design Parameters
South Muddy Creek
South Muddy Creek will be designed as a Type C4 stream with moderate sinuosity. Priority II Restoration
will be implemented with the intent being to create a stable channel with a floodplain capable of
conveying storm flows and routing the moderately high sediment loads supplied by the watershed. The
presence of an existing bridge in the middle of project requires that the floodplain bench be transitioned at
the approach and exiting of the channel. Generally, the channel appears to be vertically stable; therefore,
only minor adjustment will be made to the profile which will include re- establishment of proper riffle -pool
sequence and installation of in- stream log and brush structures. Reference data will provide the basis for
pattern and dimension adjustments, and a new floodplain bench will be excavated below the existing
terrace. Existing topsoil will be salvaged for use on the floodplain bench to facilitate vegetation success.
Sprouse Branch
The upper reach of Sprouse Branch has a mature forested canopy and channel instabilities are minor.
Enhancement (Ell) is proposed for this reach. It is anticipated that the exclusion of livestock from the
area will greatly reduce erosion and instability within this reach. Enhancement efforts will include the
installation of a grade control at the spring head to prevent further headcut migration. Supplemental
plantings will be used to treat existing bare banks. Enhancement activities will be minimally invasive to
provide for the protection of mature riparian buffer.
Middle Sprouse Branch and Lower Sprouse Branch are designed as Type B5 and Type B5c channels,
respectively. As Sprouse Branch exits the upper forested reach and flows into the pasture, the
moderately high gradient (3 %) warrants the installation of rock grade - control structures to stabilize the
vertical profile. As Sprouse Branch intersects the valley of South Muddy Creek, the gradient decreases
(1.8 %), resulting in a transition to a Type B5c stream. In both cases, construction of a stream profile that
is consistent with the valley gradient would be unstable for the sand bed material supplied by the
watershed. In order to accommodate the steeper valley gradient a terraced profile is proposed with
intermediate slopes of less than 0.2 %. Dimension adjustments will include an increase in width /depth
Middle South Muddy Creek Restoration NCEEP Mitigation Plan 26

ratio to reduce the stress on channel banks, and the excavation of a floodplain bench to provide for the
conveyance of flood flows. Existing topsoil will be salvaged for use on the floodplain bench to facilitate
vegetation success.
Iva Branch
Upper Iva Branch is a candidate for Priority I Restoration which will involve filling the existing incised
valley to raise the channel as much as eight (8) feet. Material from the excavation of South Muddy Creek
will be used to fill the valley and the woody material in the gully will be salvaged for use throughout the
rest of the project. The fill material will be placed in no greater than 2 -ft lifts and compacted to in situ soil
densities. The constructed channel will be designed as a Type B5 stream and will be vertically stabilized
through the installation of rock structures.
The short reach comprising Lower Iva Branch traverses the South Muddy Creek Valley and is designed
as a Type B5c channel. Profile, pattern, and dimension shall be adjusted to provide for proper pool
spacing, riffle -pool sequence, and reductions of stress along stream banks. A bankfull bench shall be
constructed to provide for proper conveyance of greater- than - bankfull flows. Log and rock structures will
be installed to control vertical alignment and provide aquatic habitat. In order to accommodate the steeper
gradient of the valley, a terraced profile is proposed with intermediate slopes of less than 0.2 %.
Vegetation
In order to address potential poor soil conditions on the graded bench and floodplain, EEP may plant a
mixture of leguminous and grassy cover crop species to add organic matter and fix nitrogen in the soil.
Cover crops will be disked into the soil after construction to incorporate the biomass and attempt to avoid
dominance of the site by these species. In addition, a combination of containerized woody plants and
tolerant bare roots will be planted in these sensitive areas.
Haney Tract
The Haney Tract will be established as a preservation site to protect and buffer the existing stream. The
network of dirt roads that occur throughout this tract will be barricaded in strategic locations to prevent
future vehicular access. The barricades will be constructed of boulders and large diameter tree trunks.
7.3 Narrative of Data Analysis
Hydraulic Analysis
The proposed channel sections were evaluated for their ability to convey the bankfull flows and the flood
flows (2Yr, 10Yr, 50Yr, 100Yr) of the watershed by performing a hydraulic analysis. Bankfull discharge
was determined from the revised North Carolina mountain and piedmont regional curve (NRCS) and flood
flow discharges were taken from the existing FEMA model. The analysis consisted of first modeling the
existing conditions with the HEC -RAS water surface profile model. Cross sections were taken through
the channel and the adjacent valley at representative locations throughout the project reach. Existing
hydraulic conditions were evaluated and the model calibrated based on available site data including the
presence of rack lines and testimony of past flooding from local residences. Proposed conditions were
analyzed by revising the existing sections based on the proposed channel geometry and by revising the
model to reflect proposed pattern conditions and anticipated future roughness coefficients. Comparison
of the existing and proposed HEC -RAS models provided assistance in the analysis of the sediment
transport, bankfull flow capacity, and confirmation that there will be no hydraulic trespass onto adjacent
properties.
FEMA Results
South Muddy Creek is a limited detail study stream. The HEC -RAS model of the 100 -yr event indicates no
appreciable increase in the water surface elevation within or upstream of the project. However, there is a
0.1' rise in one section upstream of the site and there is a significant decrease in the water surface
elevation upstream of the bridge that may require a CLOMR submittal. This determination will be subject
to review of the floodplain manager.
Sediment Competence Analysis
The design sections were evaluated for competence to transport the sediment supplied by the watershed.
Critical shear stress was calculated for bankfull discharge for each design section and related to particle
Middle South Muddy Creek Restoration NCEEP Mitigation Plan 27

sizes expected to be mobilized. These predicted particle sizes were compared to the caliber of the bed
material found in the existing channels. The material composing the bed of existing South Muddy Creek
consists of particles with a D50 of 19 mm and a Dmax of 57 mm. The proposed channel was designed by
calculating threshold conveyance for the maximum mobile particle and the representative particle size.
Bed material in existing Sprouse and Iva Branch is composed of primarily of sand and silt particles and
shear stress calculations suggest that profile slopes less than 0.2 % are required for bed stability (See
Appendix C for sediment transport calculations).
Sediment Capacity Evaluation
The design configuration was evaluated for sediment transport capacity by assessing continuity and
magnitude of stream power. Stream power was determined from the HEC -RAS modeling for a range of
events greater than bankfull (2Yr, 10Yr, 50Yr, 100Yr) and comparisons were made with existing and
proposed conditions. Results indicate that maintaining stream power values above 1.0 are necessary to
provide for capacity continuity and to accommodate the moderately high bed loads of the channel. The
model indicates that a spike in stream power will result at the upstream end (section 64854.66) from the
construction of the restored channel. The risk of adverse effects will be greatest in the first two years
following construction with risk diminishing as vegetation on the banks increase channel roughness.
Several channel configurations were evaluated in an attempt to reduce this effect. However, none
demonstrated a significant advantage over the design section. Additionally, flood plain pipes were
evaluated to improve floodplain performance. The model results indicated that floodplain pipes will have
only a marginal effect and may in some instances negatively influence sediment conveyance. Given
these results along with the cost of installation and presence of timber retaining walls on the bridge
approach; floodplain pipes are not recommended on this site.
Sediment capacity calculations were not performed on Iva Branch or Sprouse Branch since both streams
have low sediment supply. Stability issues associated with sediment transport on low sediment supply
streams are focused on providing the correct balance with respect to sediment transport competence.

8.0 MAINTENANCE PLAN
NCEEP shall monitor the site on a regular basis and shall conduct a physical inspection of the site a
minimum of once per 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 and may include the following:
Component/Feature
Maintenance through project close -out
Stream
Routine channel maintenance and repair activities may include
chinking of in- stream structures to prevent piping, securing of loose
coir matting, and supplemental installations of live stakes and other
target vegetation along the channel. Areas where stormwater and
floodplain flows intercept the channel may also require
maintenance to prevent bank failures and head-cutting.
Wetland
Routine wetland maintenance and repair activities may include
securing of loose coir matting and supplemental installations of live
stakes and other target vegetation within the wetland. Areas where
stormwater and floodplain flows intercept the wetland may also
require maintenance to prevent scour.
Vegetation
Vegetation shall be maintained to ensure the health and vigor of the
targeted plant community. Routine vegetation maintenance and
repair activities may include supplemental planting, pruning,
mulching, and fertilizing. Exotic invasive plant species shall be
controlled by mechanical and /or chemical methods. Any vegetation
control requiring herbicide application will be performed in
accordance with NC Department of Agriculture (NCDA) rules and
regulations.
Site Boundary
Site boundaries shall be identified in the field to ensure clear
distinction between the mitigation site and adjacent properties.
Boundaries may be identified by fence, marker, bollard, post, tree -
blazing, or other means as allowed by site conditions and /or
conservation easement. Boundary markers disturbed, damaged, or
destroyed will be repaired and /or replaced on an as needed basis.
Utility Right -of -Way
Utility rights -of -way within the site may be maintained only as
allowed by Conservation Easement or existing easement, deed
restrictions, rights of way, or corridor agreements.
Ford Crossing
Ford crossings within the site may be maintained only as allowed
by Conservation Easement or existing easement, deed restrictions,
rights of way, or corridor agreements.
Road Crossing
Road crossings within the site may be maintained only as allowed
by Conservation Easement or existing easement, deed restrictions,
rights of way, or corridor agreements.
Stormwater Management Device
Storm water management devices will be monitored and
maintained per the protocols and procedures defined by the NC
Division of Water Quality Storm Water Best Management Practices
Manual.

9.0 PERFORMANCE STANDARDS
9.1 Morphologic Parameters and Channel Stability
Restored and enhanced streams should demonstrate morphologic stability to be considered successful.
Stability does not equate to an absence of change, but rather to sustainable rates of change or stable
patterns of variation. Restored streams often demonstrate some level of initial adjustment in the several
months that follow construction and some change /variation subsequent to that is also to be expected. If
some trend is evident, it should be very modest or indicate migration to another stable form.
Dimension
Cross - section measurements should indicate little change from the as -built cross - sections. If changes do
occur, they will be evaluated to determine whether the adjustments are associated with increased stability
or whether they indicate movement towards an unstable condition.
Pattern and Profile
Measurements and calculated values should indicate stability with little deviation from as -built conditions
and established morphological ranges for the restored stream type. Annual measurements should
indicate stable bed -form features with little change from the as -built survey. The pools should maintain
their depth with flatter water surface slopes, while the riffles should remain shallower and steeper.
Substrate
Calculated D50 and D84 values should indicate coarser size class distribution of bed materials in riffles and
finer size class distribution in pools. Generally, it is anticipated that the bed material will coarsen over
time.
Sediment Transport
Depositional features should be consistent with a stable stream that is effectively managing its sediment
load. Point bar and inner berm features, if present, should develop without excessive encroachment of
the channel. Lateral and mid - channel bar features should typically not be present and if so only in
isolated instances. Bar features may be more prevalent in sand bed channels but should be transient in
nature and should occupy no more than 20% of the cross sectional area.
9.2 Vegetation
Riparian vegetation monitoring shall be conducted for a minimum of five years to ensure that success
criteria are met per USACE guidelines. Accordingly, success criteria will consist of a minimum survival of
320 stems per acre by the end of the Year 3 monitoring period and a minimum of 260 stems per acre at
the end of Year 5. If monitoring indicates either that the specified survival rate is not being met or the
development of detrimental conditions (i.e., invasive species, diseased vegetation), appropriate corrective
actions will be developed and implemented.

10.0 MONITORING REQUIREMENTS
Annual monitoring data will be reported using the EEP monitoring template. The monitoring report shall
provide a project data chronology that will facilitate an understanding of project status and trends,
population of EEP databases for analysis, research purposes, and assist in decision making regarding
project close -out.

11.0 LONG -TERM MANAGEMENT PLAN
Upon approval for close -out by the Interagency Review Team (IRT) the site will be transferred to
NCDENR or other IRT- approved stewardship entity. This party shall be responsible for periodic
inspection of the site to ensure that restrictions required in the conservation easement or the deed
restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions
shall be negotiated prior to site transfer to the responsible party.
The NCDENR Division of Natural Resource Planning and Conservation's Stewardship Program currently
houses EEP stewardship endowments within the non - reverting, interest - bearing Conservation Lands
Stewardship Endowment Account. The use of funds from the Endowment Account is governed by North
Carolina General Statute GS 113A- 232(d)(3). Interest gained by the endowment fund may be used only
for the purpose of stewardship, monitoring, stewardship administration, and land transaction costs, if
applicable. The NCDENR Stewardship Program intends to manage the account as a non - wasting
endowment. Only interest generated from the endowment funds will be used to steward the
compensatory mitigation sites. Interest funds not used for those purposes will be re- invested in the
Endowment Account to offset losses due to inflation.
12.0 ADAPTIVE MANAGEMENT PLAN
Upon completion of site construction EEP will implement the post- construction monitoring protocols
previously defined in this document. Project maintenance will be performed as described previously in
this document. If, during the course of annual monitoring it is determined the site's ability to achieve site
performance standards are jeopardized, EEP will notify the USACE of the need to develop a Plan of
Corrective Action. The Plan of Corrective Action may be prepared using in -house technical staff or may
require engineering and consulting services. Once the Corrective Action Plan is prepared and finalized
EEP will:
1. Notify the USACE as required by the Nationwide 27 permit general conditions.
2. Revise performance standards, maintenance requirements, and monitoring
requirements as necessary and /or required by the USACE.
3. Obtain other permits as necessary.
4. Implement the Corrective Action Plan.
5. Provide the USACE a Record Drawing of Corrective Actions. This document shall
depict the extent and nature of the work performed.
13.0 FINANCIAL ASSURANCES
Pursuant to Section IV H and Appendix III of the Ecosystem Enhancement Program's In -Lieu Fee
Instrument dated July 28, 2010, the North Carolina Department of Environment and Natural Resources
has provided the U.S. Army Corps of Engineers Wilmington District with a formal commitment to fund
projects to satisfy mitigation requirements assumed by EEP. This commitment provides financial
assurance for all mitigation projects implemented by the program.
