"This mitigation plan has been written in conformance with the requirements of the following:
• Federal rule for compensatory mitigation project sites as described in the Federal Register Title 33 Navigation
and Navigable Waters Volume 3 Chapter 2 Section § 332.8 paragraphs (c)(2) through (c)(14).

EXECUTIVE SUMMARY
The Uzzle Stream Mitigation Site (the "Site") is located in Johnston County, North Carolina,
approximately six miles southeast of Clayton. Water quality stressors currently affecting the Site
include livestock production, agricultural production, and improper flow dynamics due to impervious
surface runoff. The Site presents 5,982 linear feet of stream restoration and enhancement generating
3,118 Stream Mitigation Units (SMU) along Little Poplar Creek and two unnamed tributaries.
The Site is located in the Neuse River Basin within Cataloging Unit 03020201, TLW 03020201100040,
part of the Neuse Regional Watershed Planning (RWP) area, and the Wake -Johnston Collaborative
Local Watershed Plan (WJCLWP). As part of the RWP and WJCLWP, the Site is located in a
subwatershed identified as High Priority for stream corridor restoration due to current surrounding land
use, hydrologic impairment due to stormwater runoff, and projected impact from highway
development.
Consisting of pasture land and wooded areas, the Site's total easement area is 27.3 acres within the
overall drainage area of 1,312 acres. Grazing livestock have historically had access to all stream reaches
within the Site. The lack of riparian buffer vegetation, deep-rooted vegetation, and unstable channel
characteristics have contributed to the degradation of stream banks throughout the Site. Erosion and
aggradation are especially prominent at the upstream end of the Site where Little Poplar Creek enters
via culvert under HWY US -70.
Goals for the Site include an increase to hydrological function and restoration to ecological function
within the existing stream and riparian corridor, and protect these features in perpetuity. These will be
accomplished by returning streams to stable conditions by constructing an E/C type stream with
appropriate dimensions and pattern, which accommodate high-flow events, and by backfilling the
overflow channel created by continual erosion from high-flow events. In -stream structures will be
utilized for vertical stability ad to improve habitat. Buffer improvements will filter runoff from the
agricultural fields and neighboring car lot, thereby reducing nutrient and sediment loads to the channel.
Livestock exclusion fence will be installed along the easement boundary. The widening and restoration
of the riparian areas will also provide wildlife corridors throughout the Site. Benefits to be accrued
from these activities include improved water quality and terrestrial aquatic habitat.
The stream design approach for the Site is to combine the analog method of natural channel design with
analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain.
The analog method involves the use of a reference reach, or "template" stream adjacent to, nearby, or
previously in the same location as the design reach. The template parameters of the analog reach are
replicated to create the features of the design reach. The analog approach is useful when watershed and
boundary conditions are similar between the design and analog reaches (Skidmore et al., 2001).
Hydraulic geometry was developed using analytical methods to identify the design discharge.
After completion of all construction and planting activities, the Site will be monitored on a regular basis
throughout the seven-year post -construction monitoring period, or until performance standards are met.
Upon approval for closeout by the Interagency Review Team (IRT), the Site will be transferred to the
North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will 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 will be negotiated prior to site transfer to the responsible party.

1 PROJECT INTRODUCTION
1.1 Project Components
The Uzzle Stream Mitigation Site (the "Site") is located within a rural watershed in Johnston County,
approximately six miles southeast of Clayton, North Carolina. The Site lies within the Neuse River
Basin, North Carolina Department of Water Resources (NCDWR) sub -basin 03-04-02 and United
States Geological Survey (USGS) 14 -digit hydrologic unit code (HUC) 03020201100040 (Figure 1).
The Site proposes to restore 641 linear feet (LF) and enhance 5,340 LF of stream, and provide water
quality benefit for 1,312 acres of drainage area. The Site is in the Rolling Coastal Plain Level IV
ecoregion.
The Site is comprised of one easement location involving Little Poplar Creek and two unnamed
tributaries, totaling 6,983 LF, which eventually drain into the Neuse River. The stream mitigation
components are summarized in Table 1 and Figure 10. The Site is accessible from the end of Meta
Drive. Coordinates for the Site are as follows: 35.585186 N, -78.393553 W.
1.2 Project Outcomes
The streams proposed for restoration have been significantly impacted by livestock production,
agricultural practices, stormwater runoff, and a lack of sufficient riparian buffer. The Site is identified
as a High Priority candidate for stream corridor condition improvement due to its location within the
Neuse Regional Watershed Planning (RWP) subwatershed and Wake -Johnston Collaborative Local
Watershed Plan (WJCLWP). The proposed improvements to the Site will meet the water quality
improvement needs expressed in the Neuse RAT, WJCLWP, and the 2010 Neuse River Basin
Restoration Priorities (RBRP) as well as ecological improvements to the riparian corridor within the
easement.
Through stream restoration and enhancement, the Site presents 5,982 LF of proposed stream, generating
3,118 Stream Mitigation Unites (SMU) (Table 1).

2 WATERSHED APPROACH
The 2010 Neuse RBRP identified several restoration needs for the entire Neuse River Basin, as well as
for HUC 03020201. The Site watershed was identified as a Targeted Local Watershed (TLW) (HUC
03020201100040, Poplar Creek TLW), a watershed that exhibits both the need and opportunity stream,
and riparian buffer restoration. More specifically, goals outlined in the 2010 Neuse River RBRP
include:
1. Promote nutrient reduction in municipal areas through the implementation ofstormwater best
management practices;
2. Promote nutrient and sediment reduction in agricultural areas by restoring and preserving
wetlands, streams, and riparian buffers;
3. Continue targeted implementation of projects under Nutrient Offset and Buffer programs, as well
as focusing DOT -sponsored restoration in areas where they will provide the most functional
improvement to the ecosystem;
4. Support the Falls Lake Watershed Management Plan; a separate prioritization process for DMS
that will be developed in next 1-2 years;
S. Continue to implement planning initiatives including DMS Phase IV LWP for the Upper Neuse
(incorporates updated plans for the Ellerbe Creek, Lake Rogers/Ledge Creek, Lick Creek, Little
Lick Creek, and Upper Swift Creek) and the Upper Neuse River Basin Association's Upper Neuse
Watershed Management Plan; and
6. Protect, augment, and connect Natural Heritage Areas and other conservations lands.
2.1 Site Selection
The Site was identified as a stream restoration opportunity to improve water quality, habitat, and
hydrology within the Neuse River Basin, and more specifically, as a TLW within the 2010 Neuse
RBRP. The Site lends itself to accomplish multiple RBRP goals along reaches due to severely disturbed
riparian buffers, cattle access to the stream, and the historic land use, which has led to channelization.
Additionally, Department of Transportation (DOT) highway projects and private residential and
commercial development is anticipated in the future for this TLW. Many of the Site design goals and
objectives will be addressed further in Section 5. A watershed map with the Site's drainage areas is
shown on Figure 2 and watershed planning priority boundaries are shown on Figure 1.
The Site will address two of the six goals outlined in the 2010 Neuse RBRP. By excluding livestock
and establishing a conservation easement that will be protected in perpetuity, nutrient and sediment
transport from agricultural areas to Class C waterways will be reduced (RBRP Goal 2). By establishing
a conservation easement that will be protected in perpetuity, watershed connectivity will be met with
downstream parcels managed by the NC Clean Water Management Trust Fund for biodiversity and
suppression of disturbance events (Goal 6).

3 BASELINE AND EXISTING CONDITIONS
3.1 Watershed Process and Resource Conditions
Drainage Area
The Site area is comprised of Little Poplar Creek and two unnamed tributaries that flow north to south
and eventually drain into the Neuse River. The total drainage area at the downstream limits of the Site
is 1,312 acres (2.05 mi2). Primary land use within the rural watershed consists of approximately 49%
forest, 28% agricultural land, and 16% residential/urban land cover. Impervious surface accounts for
substantial land use at approximately six percent (Table 3 & Figure 4). Although the watershed is
largely forested, agriculture, commercial, and road development within the watershed are in close
proximity to the Site and play a significant role in the degradation of the Site's streams. Historic and
current land -use within the immediate Site area have allowed cattle direct access to the streams. A large
car lot to the west and the proposed widening of HWY US -70 to the north contribute to higher than
normal amounts of surface runoff and sediment load input to the Site. These activities have negatively
impacted both water quality and streambank stability along the Site streams and their tributaries. The
resulting observed stressors include excess nutrient input, streambank erosion, sedimentation, livestock
access to streams, channel modification, and the loss of functioning riparian buffers.

Surface Water Classification
These waters are protected for Class C uses. Class C waters are protected for 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 (NCDEQ 2018).
3.2 Landscape Characteristics
Vegetation
Vegetation around the main channel of Little Poplar Creek and its tributaries are primarily composed
of disturbed forest with sparse mid- or understory vegetation. The forested riparian area is grazed by
cattle and most closely resembles an interface between a Piedmont bottomland hardwood forest and
Coastal Plain small stream swamp. These areas are typically dominated by hardwoods and contain well
developed mid -tier and shrub strata. However, due to livestock grazing and soil compaction, the Uzzle
Site largely lacks a shrub stratum. On April 10, 2018 two 100 meter squared plots were surveyed along
the floodplain of the main channel to categorize the existing vegetation community (Appendix B).
Within each vegetation plot, all trees greater than or equal to five inches (12.7 centimeters) diameter at
breast height (DBH) were identified, measured, and used to calculate both basal area and stems per
acre. Trees greater than or equal to 54 inches (137 centimeters) in height were used to quantify tree
Uzzle Mitigation Plan 9 June 2018
Project #000230

species diversity. Canopy species data was calculated to quantify the existing natural community
(Schafale, 2012) (Table 4). Shrub species and herbaceous species were also identified and the percent
cover was estimated.

serotine), white oak (Quercus alba), water oak (Quercus nigra), and willow oak (Quercus phellos).
Sub -canopy species included red cedar (Jumperus virginaiana), sweetbay (Magnolia virginiana),
American holly (Ilex opaca), trumpet creeper (Campsis radicans), Carolina jasmine (Gelsemium
sempervirens), blackberry (Rubus argutus), and roundleaf greenbrier (Smilax rotundifolia). Herbaceous
species included Carolina geranium (Geranium carolinianum), bedstraw (Gallium aparine), crossvine
(Bignonia capreolata), jewelweed (Impatiens capensis), pokeweed (Phytolacca americana), Jack-in-
the-pulpit (Arisaema triphyllum), wild yam (Dioscorea villosa), and sedges (Carex spp.).
Invasive species were also found within the vegetation survey plots, and in the vicinity of the site:
Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), Nepalese browntop
(Microstegium vimineum), and multiflora rose (Rosa multiflora). Non-native species included common
chickweed (Stellaria media), common vetch (Vicia sativa), wavy bitter -cress (Cardamine flexuosa),
lesser trefoil (Trifolium dubium), and creeping buttercup (Ranunculus repens).
Existing Wetlands
A survey of existing wetlands was performed on January 5, 2017. Wetland boundaries were delineated
using current methodology outlined in the 1987 U.S. Army Corps of Engineers (USAGE) Wetland
Delineation Manual (Environmental Laboratory 1987). Soils were characterized and classified using
the Field Indicators of Hydric Soils in the United States, Version 7.0 (USDA-NRCS 2010). Within the
boundaries of the proposed Site, one large wetland is present (Figure 5), and is labeled as WA (Wetland
A). WA within the easement boundary is approximately 20.68 ac. in size, and portions of the wetland
are present outside the easement boundary. The wetland is found within the floodplain along both banks
of Little Poplar Creek for the entirety of the Site and is impacted by cattle access throughout. Vegetation
within the wetland areas is predominantly white oak (Quercus alba), water oak (Quercus nigra),
American holly (Ilex opaca), red maple (Acer rubrum), tulip poplar (Liriodendron tulipifera),
sweetgum (Liquidambar styrac flua), loblolly pine (Pinus taeda), blackberry (Rubus argutus),
Nepalese browntop (Microstegium vimineum), dogfennel (Eupatorium capillifolium), partridgeberry
(Mitchella repens), roundleaf greenbrier (Smilax rotundifolia), and muscadine (Vitis rotundifolia).
Outside of the easement and wetland areas, cattle are actively managed, and fescue is the predominant
forage. Jurisdiction determination was confirmed in the field by USACE representative Samantha
Dailey on June 22, 2017.
The US Fish and Wildlife Service (USFWS) National Wetland Inventory Map (NWI) depicts one
potential wetland area within the Site (Figure 6). During site evaluations on January 5, 2017, this
wetland was confirmed and delineated on-site by senior ecologist Jeremy Schmid.
Uzzle Mitigation Plan 10 June 2018
Project #000230

Soil Survey
The Site is located in a transition zone between the Northern Outer Piedmont and the Rolling Coastal
Plain Level IV ecoregion. The Northern Outer Piedmont is composed of mostly gneiss and schist rock
intruded by granitic plutons, and veneered with saprolite. It is lithologically distinct from the adjacent
Piedmont regions (Carolina Slate Belt & Triassic Basins), as well as from the younger unconsolidated
sediments of Rolling Coastal Plain. Rocks and soils are similar to Southern Outer Piedmont, but is
cooler with a shorter growing season. The region contains more loblolly pine compared to the Virginia
pine and shortleaf pine found in the Piedmont to the west, but it also contains local concentrations of
mountain disjunct plant species. At the eastern boundary, the Fall Line is a broad transition zone where
Piedmont rocks occur on the same landscape with Coastal Plain sediments. Some areas near this
boundary have metavolcanics and metasedimentary rocks similar to the Carolina Slate Belt.
The Rolling Coastal Plain extends south from Virginia and covers much of the northern upper coastal
plain of North Carolina. Relief, elevation, and stream gradients are generally greater than in the Middle
Atlantic Coastal Plain to the east, and soils tend to be better drained. It has a slightly cooler and shorter
growing season than the Atlantic Southern Loam Plains, but is a productive agricultural region with
typical crops of corn, soybeans, tobacco, cotton, sweet potatoes, peanuts, and wheat. The region appears
to be biologically less diverse than the Atlantic Southern Loam Plains and Carolina Flatwoods to the
south.
The Johnston County Soil Survey shows two mapping units across the Site. Map units include six soil
series. The soil series found on the Site are described below and summarized in Table 5.
Site soils are mapped by the Natural Resources Conservation Service (MRCS) as Appling-Marlboro
complex, Cecil loam, Lynchburg sandy loam, Pacolet loam, Rains sandy loam, and Wehadkee loam
within the easement (Figure 7). Lynchburg sandy loam, Rains sandy loam, and Wehadkee loam soils
are generally poorly drained loamy soils and range from zero to five percent slopes. Appling-Marlboro
complex, Cecil loam, and Pacolet loam are well -drained located on uplands or interfluves ranging from
one to 15 percent slopes. Lynchburg sandy loam, Rains sandy loam, and Wehadkee loam soils are listed
on the NRCS hydric soil list as hydric or having hydric inclusions. The surrounding upland soils are
primarily Appling-Marlboro complex, Pacolet loam.
Appling-Marlboro complex. This is a deep, well -drained soil that occurs on interfluves. They formed
from saprolite derived from granite and gneiss and/or schist, and generally occur on slopes between
one to six percent. Runoff is low and permeability is moderate. Major uses are in cultivation or pasture
land. Appling-Marlboro complex occurs in 0.2 percent of the easement.
Cecil loam. This is a deep, well -drained soil that occurs on interfluves. They formed from saprolite
derived from granite and gneiss and/or schist and generally occur on slopes between six to ten percent.
Runoff is medium and permeability moderate. Major uses are cultivation and pasture land. Cecil loam
occurs in 6.8 percent of the easement at the northern limits.
Lynchburg sandy loam. This is a very deep, somewhat poorly drained soil that occurs on marine
terraces or flats in the coastal plain. They formed in marine or fluviomarine deposits, and generally
occur on slopes between zero and five percent. Runoff is negligable and permeability is moderate.
Major uses are agricultural or woodland. Lynchburg sandy loam occurs in <0.1 percent of the Site
easement.
Pacolet loam. This is a very deep, well -drained soil that occurs on mesic Piedmont uplands. They
formed in residuum weathered mostly from felsic igneous and metamorphic rocks, and generally occur
Uzzle Mitigation Plan 11 June 2018
Project #000230

on slopes between 10 and 15 percent. Runoff and permeability is moderate. Major uses are mixed
hardwood and pine forest. Pacolet loam occurs in approximately 0.2 percent of the easement on the
downstream end.
Rains sandy loam. This is a very deep, poorly drained soil that occurs on flat depressions and Carolina
bays. They formed from marine or fluviomarine deposits, and generally occur on slopes between zero
and two percent. Runoff is negligable and permeability is moderate. Major uses include forest and
cropland. Rains sandy loam occurs in approximately 8.2 percent of the easement.
Wehadkee loam. This is very deep, poorly drained soil that occurs on floodplains from the mountains
and piedmont. They are formed in loamy sediments, and generally occur on slopes between zero and
two percent. Runoff is very slow and permeability is moderate. Major uses include forest. Wehadkee
loam occurs in approximately 84.6 percent of the easement, making it the dominant soil type on-site.

3.3 Land Use — Historic, Current, and Future
Historic aerial imagery indicates that the Project has been sparse woodland surrounded by agricultural
operations, and that the location of the streams has not significantly changed in over 50 years (Figure
8). Reforestation of wet agricultural land to the southwest of the Project, and conversion from
agriculture to impervious surface directly next to the Project on the northwestern edge has occurred
within the last 40 years. The area remains in an agricultural community with some neighboring forested
properties. Urban development began northwest of the Project in the late 1980s and farming operations
were expanded east of the Site in the early 2000s. Several watershed characteristics, such as
groundwater, vegetation, surface drainage, and potentially soil parameters have been modified. Soil
structure and surface texture have been altered from intensive agricultural operations.
The Project is currently in agricultural use as pasture land for cattle. Livestock have full access to the
project reaches, and these reaches remain heavily impacted. Little Poplar Creek and its two tributaries
have canopy cover, but virtually no functioning understory remains due to erosion and livestock access.
Outside of the Project is largely in agricultural use and remains partially forested, in addition to
extensive urban development both east and west of the Project.
Uzzle Mitigation Plan 12 June 2018
Project #000230

Future land use for the Project will include an established 27.3 -ac conservation easement, that will be
protected in perpetuity. The Project easement will have 5,982 linear feet of high functioning streams, a
minimum of 50- to 100 -foot riparian buffer, and will exclude livestock with fencing. Within the
watershed, DOT highway projects and private residential and commercial development is anticipated
in the future. Directly outside the Project, the area will likely remain in agricultural and urban use with
a proposed road widening project directly upstream and adjacent to the Project, however establishing a
conservation easement will provide nutrient and sediment mitigation to downstream portions of the
watershed.
3.4 Regulatory Considerations and Potential Constraints
Property, Boundary, and Utilities
One proposed 60 -foot wide crossing will be constructed along Reach LP5 for landowner access. The
crossing will utilize appropriate sized culverts and floodplain culverts (if needed) and be fenced and
gated to prevent livestock access to the stream channel. The Site is located within five miles of Johnston
County Airport, a General Aviation airport. The Site is not located on the extended runway centerline
(approach) and will not interfere with any airspace exclusion zones. RES will coordinate with Johnston
County Airport Authority to ensure potential conflicts are eliminated or minimized. Two parallel gas
line easements are located to the west of the Site. The proposed conservation easement will not be
impacted by the gas easement but it may limit buffer width in some areas. If feasible and appropriate,
the design will adjust the planform of the channel to provide a minimum 50 -foot buffer width in all
areas. Construction access is slightly constrained in some areas by existing mature hardwood
vegetation.
Federal Emergency Management Agency (FEMA)/ Hydrologic Trespass
According to the North Carolina Floodplain Mapping Information System, all Site reaches are located
within the FEMA 100 -year floodway of Little Poplar Creek (Zone AE) (Figure 9). Grading activities
are proposed within the Little Poplar Creek floodway for the stream restoration portion of the project
for reach LPI. Therefore, it is anticipated that a No -rise or Conditional Letter of Map Revision
(CLOMR) will be required for the project. Hydrologic trespass is a not a concern for this project. While
designing the Uzzle project, appropriate measures were taken to eliminate hydrologic trespass of the
adjacent properties. The adjacent land use will not be affected by the proposed design, and no
detrimental impacts are expected beyond the easement limits. The Site can be found on Flood Insurance
Rate Map (FIRM) Panels 1676, 1677, 1686 (map numbers 3720167600J, 3720167700J, 3720168600J),
effective date December 2, 2005.
Environmental Screening and Documentation
To ensure that a project meets environmental screening, scoping letters were sent to the regulatory
agencies of the IRT during the public notice. Responses are provided in Appendix G.
Threatened and Endangered Species
Plants and animals with a federal classification of endangered or threatened are protected under
provisions of Sections 7 and 9 of the Endangered Species Act of 1973, as amended. The US Fish and
Wildlife Service (USFWS) database (accessed 12 March 2017) lists seven threatened, endangered, and
proposed species for Johnston County, North Carolina: Neuse River waterdog (Necturus lewisi), red -
cockaded woodpecker (Picoides borealis), dwarf wedgemussel (Alasmidonta heterodon), Tar River
spinymussel (Parvaspina steinstansana), Yellow lance (Elliptio lanceolate), and Michaux's sumac
(Rhus michauxii). The Bald eagle (Haliaeetus leucocephalus) is protected under the Bald and Golden
Eagle Protection Act (BGPA), which prohibits take of bald and golden eagles. No protected species or
potential habitat for protected species was observed during preliminary Site evaluations.
Uzzle Mitigation Plan 13 June 2018
Project #000230

In addition to the USFWS database, the NC Natural Heritage Program (NHP) GIS database was
consulted to determine whether previously cataloged occurrences of protected species are mapped
within one mile of the Site. Results from NHP indicated that there are no known occurrences of
federally protected species within a one -mile radius of the Site. Based on initial site investigations, no
impacts to federally protected species are anticipated as a result of the proposed Site. A letter from
USFWS was received on November 9, 2016 to confirm these findings (Appendix G).
Cultural Resources
Cultural resources include historic and archeological resources located in or near the Site. RES
completed a preliminary survey of cultural resources to determine potential project impacts. A review
of North Carolina State Historic Preservation Office (SHPO) GIS Web Service (accessed 26 June 2017)
database did not reveal any listed or potentially eligible historic or archeological resources on the
proposed Site properties. There are no anticipated impacts from project activities to state surveyed
properties as there are none in the proposed Site vicinity. A letter from SHPO was received on
November 28, 2016 to confirm these findings (Appendix G).

3.5 Reach Summary Information
The Site area is comprised of one contiguous easement area along Little Poplar Creek, a tributary to
the Neuse River. The easement has one agricultural crossing on Reach LP5. The stream channels
include Little Poplar Creek and two unnamed tributaries, split into seven reaches by treatment type and
location (Figure 5). Results of the preliminary data collection are presented in Table 7.
In general, all or portions of reaches within the Site, do not function to their full potential. Current
conditions demonstrate significant habitat degradation as a result of impacts from livestock and high
storm flows from the upstream culvert. These impacts have dislocated some of the stream from its
floodplain and created poorly functioning overflow "channels." Floodplain canopy along the reach is
fair; however, livestock have prevented understory vegetative growth, caused localized areas of
erosion, and are a constant source of nutrients to the stream. Morphological parameters are located in
Appendix B.

Channel Classification
The streams have been classified as intermittent and perennial streams using the NCDWR Stream
Identification Form version 4.11 and are E-, and C -stream types as classified using the Rosgen stream
classification system (Rosgen, 1996). The design reaches are described in Section 6.2. Channel
characteristics are summarized in Table 4, and Appendix B. Stream determinations have been verified
by NCDWR staff (Appendix D).
Discharge
Estimating flows (discharge) for the Uzzle Site is difficult due to the channelization and agricultural
impacts of the existing streams. Several models, regression equations, and both the Coastal Plain
Regional curves and Piedmont Regional curves were used to estimate existing bankfull discharges.
Land use and slope were considered when the discharge calculations were developed. All hydraulic
and hydrologic analyses are discussed in Section 8.3. Data and analysis of the hydrologic and hydraulic
models are included as Appendix B.

Channel Stability Assessment
A modified version of the Channel Stability Assessment (CSA) method provided in "Assessing Stream
Channel Stability at Bridges in Physiographic Regions" by Johnson (2006) was used to assess channel
stability for the Uzzle existing channels and reference reach. This method may be rapidly applied on a
variety of stream types in different physiographic regions having a range of bed and bank materials.
The original Channel Stability Assessment method was designed to evaluate thirteen stability indicators
in the field. These parameters are: watershed characteristics (frequency of watershed disturbances such
as agricultural activities, urbanization, etc), flow habit, channel pattern, entrenchment/channel
confinement, bed material, bar development, presence of obstructions/debris jams, bank soil texture
and coherence, average bank angle, bank vegetation/protection, bank cutting, mass wasting/bank
failure, and upstream distance to bridge. As this method was initially developed to assess stability at
bridges, a few minor adjustments were made to remove indicators that contradict stability
characteristics of natural channels in favor of providing hydraulic efficiency at bridges. First, the
"channel pattern" indicator was altered such that naturally meandering channels scored low as opposed
to straightened/engineered channels that are favorable for stability near bridges. Secondly, the last
indicator, "upstream distance to bridge," was removed from the assessment as bridges are not a focus
of channel stability for this project. The twelve indicators were then scored in the field, and a rating of
excellent, good, fair, or poor was assigned to each project reach based on the total score.
The channel assessment results (scores and ratings) for the Uzzle project are provided in Table 8. Four
of the seven project streams received "Fair" ratings, while three reaches received "Good" ratings. The
reach score trended upward as we move downstream through the project. This improvement correlated
with a decrease in bank cutting and wasting in the downstream portion of the project. Overall, the
upstream project streams appear to be actively adjusting due to constant stress from surrounding
livestock. The downstream portions of the project are stable but have localized areas of erosion and
deposition due to cattle impacts and upstream sediment inputs. These characteristics are reflected in the
weaker CSA scores throughout the project.
Uzzle Mitigation Plan 17 June 2018
Project #000230

Table 8. Channel Stability Assessment Results
* Excellent (0 < Score <= 36), Good (36 < Score <= 72), Fair (72 < Score <= 108), Poor (108 < Score <= 144)
Bankfull Verification
Bankfull is difficult and often times impossible to accurately identify on actively maintained channels
and agricultural ditches. The usual and preferred indicators rarely exist, and other factors may be taken
into consideration in order to approximate a bankfull stage. Other factors that may be used are wrack
lines, vegetation lines, scour lines, or top of a bankfull bench; however, complete confidence should
not be placed on these indicators. Along the proposed restoration reaches, the channel is generally
entrenched, which means bankfull indicators were very limited or non-existent. Therefore, bankfull
stage was estimated by using Coastal Plain Regional Curves and other hydrologic analyses, existing
cross-sections, and in-house spreadsheets to estimate bankfull area and bankfull discharge.

4 FUNCTIONAL UPLIFT POTENTIAL
The Stream Functions Pyramid Framework (Harman et. al. 2012) separates stream functions to describe
project objectives, existing conditions assessments and monitoring, performance metrics, and design
criteria. The Framework separates stream functions into five categories, ordered into a hierarchy, which
communicate the interrelations among functions and illustrate the dependence of higher level functions
(biology, physiochemical and geomorphology) on lower level functions (hydrology and hydraulics).
Functions that affect the greatest number of other functions are illustrated at the base of the pyramid,
while functions that have the least effect on other functions are illustrated at the top of the pyramid.
The Pyramid is illustrated below (Chart 1).
Stream Functions Pyramid
A Guide for Assessing & Restoring Stream Functions > ovERviuw
Chart 1. Stream Functions Pyramid
wdarmarfftuaaro-r Oan"cum Wmamfthanirs
Fischenich (2006) found that the most critical functions include those that address hydrodynamic
processes, sediment transport processes, stream stability and riparian buffer restoration. By addressing
these fundamental functions and processes, a restored stream and riparian system are capable of
supporting more dependent functions that typically require time to establish, such as diverse biological
communities, chemical and nutrient processes, diverse habitats and improved water and soil quality.
The objectives of this Site will address the most critical functional objectives that will allow for a more
restored stream and riparian system over time.
While traditional mitigation approaches have generally relied on surrogate measures of success (i.e.
linear feet of restoration) for determining SNfU credit yields, a function -based approach provides a
Uzzle Mitigation Plan 21 June 2018
Project #000230

more objective and flexible approach to quantify the expected ecological benefits of a mitigation
design. Additionally, a functional based approach broadens the reach -scale goals of a restoration project
by contextualizing the functional uplift to the watershed scale. The proposed Uzzle Stream Mitigation
Site will provide numerous ecological and water quality benefits within the Neuse River Basin by
applying an ecosystem restoration approach. The restoration approach at the reach scale of this Site
will have the greatest effect on the hydraulic and geomorphology function of the system but will benefit
the upper-level functions (physiochemical and biology) over time and in combination with other sites
within the watershed. Anticipated functional benefits and improvements within the Site, as based on
the Function -Based Framework, are outlined in Table 9.
4.1 Anticipated Functional Benefits and Improvements
Hydrology
According to the Stream Functions Pyramid Framework, hydrology is defined as the transport of water
from the watershed to the channel. Therefore, this project does not intend to make significant
improvements to the already functioning hydrology. Mainly, landuse within the Project's catchment
area will not be altered outside of the easement area, meaning hydrologic parameters such as reach
runoff, flow duration, and discharge will continue to be determined by existing watershed
characteristics occurring beyond the boundaries of the Project. Although hydrology will remain largely
unaffected by the project, restoration design and activities will account for poor watershed conditions
and will provide considerable functional uplift through the following functional tiers of the Pyramid.
Hydraulic
The hydraulic function of the Pyramid Framework is defined as the transport of water in the channel,
on the floodplain, and through sediments. Perhaps the greatest potential uplift at the Project will be
achieved through establishing healthy floodplain connectivity. Reaches at the Site do not have stable
flow dynamics. Reaches in which stable flow dynamics are not functioning or functioning at risk will
be improved to functioning by constructing a new channel that is geometrically stable based on the
Site's hydrology inputs. Additionally, instream structures will be installed to address the energy and
erosive power of the water so that a stable base flow is achieved post -project.
Geomorphology
Geomorphology, as defined within the Pyramid Framework, is the transport of wood and sediment to
create bed forms and dynamic equilibrium. Sediment transport will be improved in reaches that are
currently function -at -risk or not functioning by designing a channel on the restoration reach that is
sinuous and sized so that water velocities are maintained in a stable manor and allows for sediment to
move efficiently through the other six downstream reaches. Large Woody Debris Transport and Storage
will be improved through the addition of woody debris to the system by installing in -stream structures
on the restoration reach such as log vanes, root wads, log weirs, and log toes. Some of these woody
structures will also deliver functional uplift by providing aquatic habitat. The restoration reach will be
designed to accumulate woody debris by having defined shallow riffles where cobble catches and holds
woody debris and leaf packs. In reaches proposed for restoration, lateral stability is not functioning. To
achieve functioning lateral stability, sinuous channels will be constructed with grade -control structures,
graded banks, and live -stake planted banks that will significantly reduce erosion rates compared to
existing conditions. Existing riparian vegetation is either functioning at risk or not functioning in
Project reaches. Therefore, riparian buffers will be planted out to a minimum of 50 feet to improve the
riparian vegetation to functioning levels, while also providing terrestrial habitat. Bed form diversity
will be improved in restoration reaches by designing natural riffle -pool sequences in constructed
channels based on reference reach conditions. This bed form diversity will also further improve aquatic
habitat. All of these functional parameters are interconnected and ultimately depend on each other in
Uzzle Mitigation Plan 22 June 2018
Project #000230

order to function properly. Therefore, by focusing improvements on these parameters, the restored
channels will achieve dynamic equilibrium and provide maximum geomorphic functional uplift.
Physiochemical
The Pyramid Framework defines the physicochemical category as temperature and oxygen regulation
and the processing of organic matter and nutrients. Although this Project would support the overarching
goal in the Neuse River Basin Priorities to promote nutrient and sediment reduction in agricultural
areas, it is difficult to make the direct link to this reach -scale stream restoration project to a measurable
reduction in nutrients and sediments because they depend on many variables. However, several
restoration practices are known to help reduce nutrients and sediment although it is not feasible to
measure these results directly at the project level. These activities include cattle exclusion and direct
removal of fecal inputs, filtering sediment from runoff through buffer areas, conversion of active farm
fields to forested buffers, and improved denitrification and nutrient uptake through buffer zones. It is
anticipated that temperature regulation will also be improved through the restoration of canopy tree
species in the stream buffer areas. Oxygen regulation will occur through two actions: first the
temperature of the water directly impacts the amount of gas held by the water. Therefore, through buffer
plantings, the channel will experience shading and temperature will decrease; thereby, increasing
dissolved oxygen content. Secondly, log structures placed in the stream will create aeration zones where
oxygen dissolves more readily than in a stagnant air -water surface exchange. The processing of organic
matter will improve once healthy riffles are shallow enough to catch twigs and branches that then retain
leaves. Many of these physiochemical benefits occur slowly over time and are dependent on multiple
variables within the stream ecosystem. Therefore, it is not guaranteed that physicochemical parameters
will show drastic improvements within the monitoring time -frame of this project. However, direct
physicochemical monitoring measurements will ideally show a positive trend toward water quality
betterment, and will serve as a useful tool to help project the long-term benefits of the Site in terms of
the Stream Functions Pyramid Framework.
Biology
The highest category of the Pyramid is biology and is defined as the biodiversity and life histories of
aquatic and terrestrial life, specifically referring to animals. As mentioned for the physiochemical
category, at a reach and project level it is not guaranteed that high functional uplift for biology will
necessarily be demonstrated at the Site within the monitoring time -frame of this project. However,
macroinvertebrate sampling should ideally demonstrate a trend toward higher species diversity in the
latter period of the seven-year monitoring window. It is also important to understand that since life
histories depend on all the lower -level functional categories (Hydrology, Hydraulics, Geomorphology,
and Physicochemical), benefit to biology over time and in combination with other projects within the
watershed is anticipated.

5 MITIGATION PROJECT GOALS AND OBJECTIVES
Through the comprehensive analysis of the Site's maximum functional uplift using the Stream
Functions Pyramid Framework, specific attainable goals and objectives will be realized by the Site.
These goals clearly address the excess nutrient input, streambank erosion, and sedimentation that were
identified as major watershed stressors in the 2010 Neuse RBRP. The Site will address outlined RBRP
Goals 2 and 6 (listed in Section 2).
The Site Goals are:
• Improve water transport from watershed to the channel in a non-erosive manner in a stable
channel;
• Improve water quality within the restored channel reach and downstream water sources by
reducing sediment and nutrient loads, and increasing dissolved oxygen levels;
• Improve flood flow attenuation on-site and downstream by allowing for overbank flows and
connection to the active floodplain; and
• Improve ecological processes by reducing water temperature, improving terrestrial and aquatic
habitat, and restoring a native plant community.
The Site objectives to address the goals are:
• Design and construct stable stream channels with appropriate pattern, dimension, and profile
based on reference reach conditions;
• Permanently exclude livestock from stream channels and their associated buffers;
• Add in -stream structures and bank stabilization measures to protect restored and enhanced
streams;
• Reduce bank height ratios and increase entrenchment ratios to reference reach conditions;
• Increase forested riparian buffers to at least 50 feet on both sides of the channel along all
reaches with a coastal plain hardwood riparian community;
• Treat exotic invasive species; and
• Establish a permanent conservation easement on the Site.
Anticipated functional benefits and improvements within the Site area, as based on the Function -Based
Framework are outlined in Table 9.
Limitations to achieving these watershed goals arise by remaining constrained to our Site boundaries.
While we are restoring the habitat and streams to stable and effective conditions that achieve our goals
within the Site parcels, we are unable to influence the effect of poor riparian buffers and livestock
impact in other areas within the watershed. However, through this Site's connectivity with other
projects in the watershed and responsible stewardship of current restoration projects, overall watershed
functionality and health will improve to meet the RBRP goals.

6 MITIGATION WORK PLAN
6.1 Reference Stream Studies
The restoration portions of the Site are characterized by livestock practices. Portions of the Site were
historically diverted to form poorly -functioning stream channels. Physical parameters of the Site were
used, as well as other reference materials, to determine the target stream type. The "Classification of
the Natural Communities of North Carolina" was also used to narrow the potential community types
that would have existed at the Site (Schafale, 2012). An iterative process was used to develop the final
information for the Site design.
Targeted reference conditions included the following:
• Located within the Physiographic Region and ecoregion,
• Similar watershed size,
• Similar land use on-site and in the watershed,
• Similar soil types on-site and in the watershed,
• Ideal, undisturbed habitat — several types of woody debris present,
• Similar topography,
• Similar slope,
• Pattern common among Coastal Plain streams, and
• Minimal presence of invasive species.
Obtaining property owner information and owner authorization for access was another factor in locating
suitable reference sites for the project. For this project, there was no predetermined amount of reference
sites needed as long as the site was suitable and met the parameters. Several potential reference sites
were assessed, and their characteristics were noted. It is difficult to find reference sites on the coastal
plain because many have been disturbed by farming or urban development. Most streams tend to be
modified ditches and may have some of the characteristics that are sought in a reference, but too few
to make it an ideal reference for the project site. One reference stream site that proves to be ideal in
both geomorphology and habitat is located near the intersection of Little Divine Road and Howard
Drive. Located approximately 14 miles north of the project site the reference reach is in the wooded
area east of Howard Drive.
Reference Watershed Characterization
The reference stream is an unnamed tributary that flows west to east and drains to Hannah Creek. The
portion of the reference reach that was surveyed and analyzed is approximately 275 feet long. The
drainage area for the reach is 1.24 square miles (795 acres). The land use in the watershed is
characterized by mostly agricultural (52 percent), mixed pines and hardwoods (42 percent), residential
(four percent), and open water (two percent).
The current State classification for reference reach is undefined, but the tributary runs into Hannah
Creek. Hannah Creek is defined as Class C NSW (NCDEQ 2018). Class C waters are suitable for aquatic
life, secondary recreation, and agricultural usage. The NSW is a designation for nutrient sensitive waters
— intended for waters needing additional nutrient management due to being subject to excessive growth
of microscopic or macroscopic vegetation.
Reference Discharge
Several hydrologic models/methods were used to develop a bankfull discharge for the reference site.
Existing drainage area, land use, slope, roughness, and cross-sectional area were all factors considered
Uzzle Mitigation Plan 26 June 2018
Project #000230

when performing the calculations. Using a combination of Coastal Plain Regional Curves, in-house
spreadsheet tools, and a project specific regional flood frequency analysis, the existing discharge was
found to be around 34 cubic feet per second (ft3/s).
Reference Channel Morphology
In comparison to the restoration reaches, the reference reach is approximately the same size as Reach
LP 1 when comparing pattern, dimension and profile, therefore a scaling factor was not needed for the
design. The stream was typically 12.2 feet wide and 1.65 feet deep. The cross-sectional area was
typically around 15.4 square feet with a width to depth ratio around 9.7.
Reference Channel Stability Assessment
The reference reach was stable and showed no evidence of incision or erosion in the portion that was
surveyed and analyzed. The stream appeared to maintain its slope and had sufficient amounts of
vegetation to secure its banks. Riparian buffer widths exceeded fifty feet on each side. The Channel
Stability Assessment results (scores and ratings) for the reference reach are provided above in Table 8
(Section 3.5). The reference reach received a "Good" rating as the channel demonstrates a stable
meandering pattern and a well vegetated riparian buffer.
Reference Bankfull Verification
Typical indicators of bankfull include vegetation at the bankfull elevation, scour lines, wrack lines,
vegetation lines, benches/inner berm, and point bars. Throughout the entire length of the reference
reach, bankfull is located at the top of bank elevation. The accuracy of this bankfull stage is verified by
the Coastal Plain Regional Curves and hydrologic analyses using existing cross sections to calculate
area and discharge. Evidence that can further support the location of bankfull is the lack of any bench
or berm features within the channel, and wrack lines present within the floodplain.
Reference Riparian Vegetation
The reference reach riparian community is characteristic of a Coastal Plain Small Stream Swamp
community. This community was determined to have had past disturbance altering the species
composition. It is anticipated that a local seed source for high dispersal species is present and will
disperse across much of the mitigation site. These species are often found in early successional
communities and quickly fill disturbance gaps. Because many of these high dispersal species often
become aggressive in these sites, they are not included in the Restoration Planting List (Section 6.3).
Hardwood species typical of the target community were observed in adjacent and nearby communities,
providing further guidance for planting efforts.
6.2 Design Parameters
Stream Restoration Approach
Stream restoration and enhancement efforts along the tributaries at the Uzzle Stream Mitigation site
will be accomplished through analyses of geomorphic conditions and watershed characteristics. The
design approach applies a combination of analytical and reference reach based design methods that
meet objectives commensurate with both ecological and geomorphic improvements. Proposed
treatment activities may range from minor bank grading and planting to re-establishing a stable
planform and hydraulic geometry. For reaches requiring full restoration, natural design concepts have
been applied and verified through rigorous engineering analyses and modeling. The objective of this
approach is to design a geomorphically stable channel that provides habitat improvements and ties into
the existing landscape.
Uzzle Mitigation Plan 27 June 2018
Project #000230

The Uzzle Site will include Priority I Restoration, and Enhancement Level II. The Priority I Restoration
reach will incorporate the design of a single -thread meandering channel, with parameters based on data
taken from the reference site described above, published empirical relationships, NC Coastal Plain
Regional Curves, and hydrologic and hydraulic analyses. As a result of the restoration of planform and
dimension, frequent overbank flows and a restored riparian buffer will provide the appropriate
hydrology and sediment transport throughout this coastal plain watershed. A conceptual plan view is
provided in Figure 10.
Current stream conditions along the proposed restoration reach exhibit habitat degradation as a result
of impacts from culvert outfall velocities and cattle access. Though the riparian buffer is in good
condition throughout most of the project area, livestock have direct access to the channel limiting the
buffers effectiveness.
The Uzzle Site design approach began with a thorough study of existing conditions, including the onsite
streams, valleys, and watershed. Design parameters, including active channel, habitat and floodplain
features were developed from analyses performed on the reference site data. Analytical design
techniques were used to determine the design discharge and to verify the design as a whole.
Engineering analyses were performed using various hydrologic and hydraulic models to verify the
reference reach based design. A combination of methods (including Hydraflow Hydrographs, regional
curves and flood frequency analysis) were used to calculate flows received by the channel for bankfull
and other significant storm events. Through this hydrologic analysis, the design discharge (typically
referenced as bankfull or dominant discharge) was determined, and the subsequent design was based
on this calculated discharge. Design parameters developed through the analyses of reference reach data
and hydrologic and hydraulic modeling were confirmed using the Stable Channel Design function
components within HEC -RAS and through spreadsheet tools.
Engineering analyses were performed concurrently to geomorphic and habitat studies. While the stream
design was verified by simulations of hydrology and fluvial processes, analogs of desirable habitat
features were derived from reference sites and integrated into the project design. Both riparian habitat
features, excavated floodplains, and in -stream structures such as brush toes, log j -hooks, and log drops
were used throughout the project to act as grade control and for bank stabilization by dissipating and
redirecting the stream's energy. Bank stability will also be enhanced through the installation of live
stakes that include native species (e.g. black willow (Salix nigra) and silky dogwood (Cornus
amomum)).
Sections of abandoned stream channel will be backfilled to the elevation of the floodplain in areas
adjacent to the new channel with material excavated onsite and by installing channel plugs where
necessary. The floodplain will be planted with native species creating a vegetated buffer, which will
provide numerous water quality and ecological benefits. Stream banks will be stabilized using a
combination of grading, erosion control matting, bare -root plantings, native material revetment
techniques (i.e. bioengineering), structure placement, and sod transplants where possible. The stream
and adjacent riparian areas will be protected by a permanent conservation easement.
The Uzzle Stream Mitigation Site has been broken into the following design reaches:
Reach LN — Reach beginning at northern limits of the project flowing south to Reach LP2 totaling
640 linear feet of Priority I Restoration. Wooded active pasture is located adjacent to the reach. Priority
I Restoration is proposed along Reach LP 1 to address channel degradation and bank erosion caused by
cattle access and high energy storm flows from the upstream culvert. The design approach will
including meandering the proposed channel within the natural valley, aligning the channel with the
Uzzle Mitigation Plan 28 June 2018
Project #000230

upstream culvert, backfilling the existing stream, reconnecting the channel to its floodplain, and
excluding livestock from the stream. A minimum 50 -foot buffer will be established and planted with
native riparian vegetation. Woody debris and grade control structures will be installed along the bed to
improve in -stream habitat and stability. The watershed that drains to the upper end of the project is
approximately 1,124 acres, and land use it primarily agricultural. The drainage area at the downstream
end of the reach is 1,174 acres.
Reaches LP2 through LP7
Enhancement Level II is proposed for all remaining Reaches LP2 through LP7 which will include
treatment of invasive vegetation, debris removal, and livestock exclusion. A minimum 50 -foot buffer
will be established along the reach and will be planted with native riparian vegetation where existing
vegetation is non-native or limited density. The drainage area at the downstream end of the reaches is
1,312 acres.
Reach LP2 — Reach begins at the downstream end of Reach LPI and flows south through wooded
active pasture to the confluence of Reach LP3 and Reach LN. Reach LP2 totals 1619 linear feet of
Enhancement Level II.
Reach LP3 — Reach begins at the edge of a gas pipeline easement and flows east to the confluence with
Reach LP2. Reach LP3 totals 200 linear feet of Enhancement Level II. Wooded active pasture is located
adjacent to the reach.
Reach LN — Reach begins at the downstream end of LP2 and LP3 and flows south through wooded
active pasture to Reach LP5 totaling 559 linear feet of Enhancement Level II.
Reach LP5 — Reach begins at the downstream end of Reach LP4 and flows south through wooded
active pasture and ends at a confluence with Reach LP6. A 61 linear foot easement break is located in
this reach to accommodate a proposed crossing. Reach LP5 totals 2,258 linear feet of Enhancement
Level II.
Reach LP6 — Reach begins at the edge of a gas pipeline easement and flows east to the confluence with
Reach LP5. Reach LP6 totals 387 linear feet of Enhancement Level II. Wooded active pasture is located
adjacent to the reach.
Reach LP7 — Reach begins at the confluence of Reach LP5 and LP6 flowing southeast through wooded
active pasture toward the Neuse River. Reach LP7 totals 319 linear feet of Enhancement Level II.
Design Discharge
Based upon the hydrologic analyses described below, design discharges were selected that fall near
model results for the 1.1 -year Flood Frequency Analysis for the restoration reach. The selected flow
for reach LPI is 34 ft'/s. This discharge will provide frequent inundation of the adjacent floodplain.
The design discharge was selected based on the following rationale:
• The calculated bankfull discharge for the analog/reference reach and existing reaches fall near
the results of the 1.1 -year Flood Frequency Analysis,
• The results of the 1.1 -year Flood Frequency Analysis are slightly higher than the NC regional
curve (Doll et al., 2003), and
• Selecting design discharges around the 1.1 -year storm events allows frequent inundation of the
adjacent floodplain.
Uzzle Mitigation Plan 29 June 2018
Project #000230

Design Methods
There are three primary methods that have demonstrated success in stream restoration: analog,
empirical, and analytical. All three methods have advantages and limitations, and it is often best to
utilize more than one method to address site-specific conditions or to verify the applicability of design
elements. This is particularly true in developed watersheds where existing conditions do not always
reflect current inputs and events, and sediment and hydrologic inputs may remain unstable for some
time. Combinations of analytical and analog methods were used to develop the stream designs for the
Uzzle site.
Analytical Approach
Analytical design is based on principles and processes considered universal to all streams, and can
entail many traditional engineering techniques. The analytical approach utilizes continuity, roughness
equations, hydrologic and hydraulic models, and sediment transport functions to derive equilibrium
conditions. Since the project is located within a rural watershed, restoration designs are based on
hydrologic and hydraulic analyses, including rainfall -runoff models to determine design discharges
coupled with reference reach techniques.
Analog Approach
The analog method of natural channel design involves the use of a "template" or reference stream
located near the design reach, and is particularly useful when watershed and boundary conditions are
similar between the design and analog reaches (Skidmore et al., 2001). In an analog approach, the
planform pattern, cross-sectional shape, longitudinal profile, and frequency and locations of woody
debris along the analog reaches are mimicked when developing the design parameters for the subject
stream.
1. The appropriate bankfull cross-sectional area (CSA) of each design reach was calculated using
an in-house spreadsheet based on Manning's Equation. The input parameters included the
design discharge as determined by the hydrologic analysis described above, and proposed slope
based on site conditions and the sinuosity measured for the analog reach.
The cross-sectional shape was adjusted within the spreadsheet to replicate the width -depth
ratios and side slopes surveyed along the analog reach, while also maintaining the CSA
necessary to convey the design discharge.
3. The scaling factor is determined from the ratio of the design top width to the analog top width
(Table 10). For this project, several cross-sections and planform geometry were measured at
the analog site, resulting in an average width of 12.2 feet.
4. Pool cross-sectional areas were calculated using both typical reference reach techniques and
the analog approach. Design CSA areas were determined using the measured analog ratios of
shallow/riffle CSA to pool CSA as applied to the design CSAs. The pool cross-sectional shape
was adjusted within the in-house spreadsheet as described above in step 2.

Typical Design Sections
Typical cross sections for shallows and pools are shown on the design plan sheets in Appendix A. The
cross-section dimensions were developed for the two design reaches by using a WK Dickson in-house
spreadsheet described in Section 6.2 of this plan. The cross-sections were altered slightly to facilitate
constructability; however, the cross-sectional area, width to depth ratio, and side slopes were preserved.
Typical pool sections include pools located on straight reaches and pools on meander bends.
Meander Pattern
The design plans showing the proposed channel alignment are provided in Appendix A. The meander
pattern was derived directly from the analog reach and was altered in some locations to provide
variability in pattern, to avoid onsite constraints, to follow the valley pattern, and to make the channel
more constructible. The morphologic parameters summarized in the Appendix B were applied
wherever these deviations occurred.
Longitudinal Profiles
The design profiles are presented in Appendix A. These profiles extend throughout the entire Site for
the proposed channel alignment. The profiles were designed using the analog reach bed features that
were sized with the scaling factors. The bed slopes and bankfull energy gradients were determined for
each design reach based on the existing valley slope and the sinuosity of the design reach. A mix of
rock and log structures will be utilized in the design to control grade, divert flows, and provide
additional habitat diversity and stability.
In -Stream Structures
Structures will be incorporated into the channel design to provide additional stability and improve
aquatic habitat. Native materials and vegetation will be used for revetments and grade control structures
where applicable.
Woody debris will be placed throughout the channel at locations and at a frequency that is similar to
those observed in the analog reaches. Woody habitat features installed will include brush toes, log sills,
and log j -hooks. To provide additional bank stability, sod mats harvested onsite will be installed along
stream banks during construction if and when feasible. Sod mats will only be harvested and used if
comprised of appropriate vegetation. The use of sod mats that include aggressive turf grasses will be
avoided. Sod mats are natural sections of vegetation taken from the banks when they were cut during
construction and are about nine inches thick. Before installation, proposed banks are graded lower than
specified to accommodate the thickness of the mat. The mats are placed on top of the bank to act as a
natural stabilizer of native species, and they grow much faster than the combination of coir fiber matting
and seeding. Other bank stability measures include the installation of live stakes, log sills, and brush
toes. Typical details for proposed in -stream structures and revetments are in Appendix A.
Data Analysis
Stream Hydrologic Flows
Hydrologic evaluations were performed for the design reaches using multiple methods to determine
and validate the design bankfull discharge and channel geometry required to provide regular floodplain
inundation. The use of various methods allows for comparison of results and eliminates reliance on a
single model. Peak flows (Table 11) and corresponding channel cross-sectional areas were determined
for comparison to design parameters using the following methods:
Uzzle Mitigation Plan 31 June 2018
Project #000230

• Regional Flood Frequency Analysis,
• AutoCAD's Hydraflow Hydrographs,
• NC and VA/MD Regional Curves for the Coastal Plain, and
• US Geological Survey (USGS) regional regression equations for rural conditions in the Coastal
Plain.
Regional Flood Frequency Analysis
A flood frequency analysis was completed for the study region using historic gauge data on all nearby
USGS gauges with drainage areas less than 6,400 acres (10 mit) which passed the Dalrymple
homogeneity test (Dalrymple, 1960). This is a subset of gauges used for USGS regression equations.
Regional flood frequency equations were developed for the 1.1-, 1.5-, and 2 -year peak discharges based
on the gauge data. Discharges were then computed for the design reach. These discharges were
compared to those predicted by the discharge regional curve and USGS regional regression 2 -year
discharge equations.
AutoCAD's Hydraflow Express
Hydraflow Express was used to simulate the rainfall -runoff process and establish peak flows for the
watersheds. This model was chosen over the U.S. Army Corps of Engineers model HEC -HMS because
it allows the user to adjust the peak shape factor for the watershed conditions. Rainfall data reflecting
100, 284 and 484 peak shape factors were used along with a standard Type II distribution, and NRCS
hydrology (time of concentrations and runoff curve numbers), to simulate the rainfall -runoff process.
A 100 peak shape factor was determined to be the most representative for this watershed.
Regional Curve Regression Equations
The North Carolina Coastal regional curves by Doll et al. (2003) and Sweet and Geratz (2003), and the
Virginia/Maryland (Krstolic and Chaplin, 2007) Coastal Plain regional curves for discharge were used
to predict the bankfull discharge for the site. The NC regional curves predicted flows that are similar to
those predicted by the 1.1 -year flood frequency, while the VA/MD curves are comparable to flows
predicted by the 1.5 -year flood frequency equation. The regional curve equations for NC discharges by
Doll et al. (2003) (1), Sweet and Geratz (2003) (2), and VA/MD (3) discharges are:
(1) Qbkj=-16.56*(DA)0.72 (Doll et al., 2003)
(2) Qbkj=8.49*(DA)0.76 (Sweet and Geratz, 2003)
(3) Qbkj= 28.3076*(DA)0.59834 (Krstollc et al., 2007)
Where Qbkt=bankfull discharge (ft3/s) and DA=drainage area (mi2).
USGS Regional Regression Equations
USGS regression equations estimate the magnitude and frequency of flood -peak discharges (Weaver,
et al., 2009). The regression equations were developed from gauge data in different physiographic
regions of the Southeastern United States. For this analysis, there was only concern for the 2 -year return
interval. The equation for the rural Piedmont (Hydrologic Region X) is:

Sediment Transport Analysis
An erosion and sedimentation analysis was performed to confirm that the restoration design creates a
stable sand bed channel that neither aggrades nor degrades over time. Typically, sediment transport is
assessed to determine a stream's ability to move a specific grain size at specified flows. Various
sediment transport equations may be easily applied when estimating entrainment for gravel bed
streams; however, these equations are not as effectively applied to sand bed channels where the entire
bed becomes mobile during geomorphically significant flows. Therefore, more sophisticated modeling
techniques were used to analyze the stream design for this project. The following methods and functions
were utilized during the sediment transport analysis:
Permissible Shear Stress Approach
Permissible Velocity Approach
Shear Stress Approach
Shear stress is a commonly used tool for assessing channel stability. Allowable channel shear stresses
are a function of bed slope, channel shape, flows, bed material (shape, size, and gradation),
cohesiveness of bank materials, and vegetative cover. The shear stress approach compares calculated
shear stresses to those found in the literature. Shear stress is the force exerted on a boundary during the
resistance of motion as calculated using the following formula:
(5) t = yRS
T = shear stress (lb/ft')
y = specific gravity of water (62.4 lb/ft')
R = hydraulic radius (ft)
S = average channel slope (ft/ft)
Table 12. Comparison of Allowable and Proposed Shear Stresses

1(Fischenich, 2001)
Review of the above table shows that the proposed shear stresses for the Uzzle design reaches fall
between the critical shear stress (shear stress required to initiate motion) and the allowable limits.
Therefore, the proposed channel should remain stable.
VelocityApproach
Published data are readily available that provide entrainment velocities for different bed and bank
materials. A comparison of calculated velocities to these permissible velocities is a simple method to
aid in the verification of channel stability. Table 13 compares the proposed velocities calculated using
Uzzle Mitigation Plan 33 June 2018

Handbook (MRCS, 2007).

6.3 Vegetation and Planting Plan
Plant Community Restoration
The restoration of the plant communities is an important aspect of the restoration project. The selection
of plant species is based on what was observed at the reference reach, species present in the forest
surrounding the restoration site, and what is typically native to the area. Several sources of information
were used to determine the most appropriate species for the restoration project. The reference stream is
located within a disturbed Coastal Plain Small Stream Swamp. Species dominant in the canopy included
sweetgum, red maple, tulip poplar, swamp tupelo, and various oak species (Quercus sp.) in the canopy.
Shrubs included sweetbay and American holly. The reference site was chosen due to the stability of the
channel, the physical structure of the forest community, and to evaluate stream habitat. The species
present are indicative of early successional species that have high dispersal rates. The mitigation site
also supports many species typical of this community type due to its past disturbance history. Typically,
Coastal Plain Small Stream Swamps would occur along the stream banks and adjacent floodplain of
the proposed restoration site.
Coastal Plain Small Stream Swamp will be the target community type and will be used for all areas
within the project, as well as for buffer around the site. The plant species list has been developed and
can be found in Table 14. Species with high dispersal rates are not included because of local occurrence,
adjacent seed sources, and the high potential for natural regeneration. The high dispersal species include
red maple, tulip poplar, and sweetgum.
The restoration of plant communities along the Site will provide stabilization and diversity. Planting
activities will be divided into three approaches. Approach one is the full restorative planting
surrounding Reach LP 1, in response to disturbance during construction activities. Approach two is the
projected areas of supplemental planting along the easement boundary and downslope from the current
gate where cattle access the floodplain from the above pasture. Approach three is low density
supplemental planting in small canopy openings throughout the Project, caused by historic cattle access,
and will be identified as -needed during the other planting activities. Supplemental planting in
approaches two and three will utilize primarily oaks (Quercus spp.) and bald cypress (Taxodium
distichum).
For rapid stabilization of the stream banks (primarily outside meanders), a mix of or all of either
cottonwood (Populus deltoides), silky dogwood (Cornus sericea), and/or black willow (Salix nigra)
were chosen for live stakes along the restored channel because of their rapid growth patterns and high
success rates. Willows grow at a faster rate than the species planted around them, and they stabilize the
stream banks. Willows will also be quicker to contribute organic matter to the channel. When the other
species are bigger, the black willows will slowly stop growing or die out because the other species
would outgrow them and create shade that the willows do not tolerate. The live stake species will be
planted along the outside of the meander bends three feet from the top of bank, creating a three-foot
Uzzle Mitigation Plan 34 June 2018
Project #000230

section along the top of bank. The live stakes will be spaced three feet apart with alternate spacing
vertically. Live stakes will also be utilized throughout the enhancement portions of the Project to ensure
bank stabilization where historic cattle access have caused the lack of understory vegetation along
channel banks. Since the goal is to achieve a Coastal Plain Small Stream Swamp, bare root bald cypress
will also be planted in clumps of six, approximately every 100 feet, along bank meanders to aid in bank
stabilization.

On -Site Invasive Species Management
Treatment for invasive species will be required within all grading limits associated with stream
restoration. Invasive species will require different and multiple treatment methods, depending on plant
phenology and the location of the species being treated. All treatment will be conducted so as to
maximize its effectiveness and reduce chances of detriment to surrounding native vegetation. Treatment
methods will include mechanical (cutting with loppers, clippers, or chain saw) and chemical (foliar
spray, cut stump, and hack and squirt techniques). Plants containing mature, viable seeds will be
removed from the site and properly disposed. All herbicide applicators will be supervised by a certified
ground pesticide applicator with a North Carolina Department of Agriculture and Consumer Services
(NCDA&CS) license and adhere to all legal and safety requirements according to herbicide labels and
NC and Federal laws. Management records will be kept on the plant species treated, type of treatment
employed, type of herbicide used, application technique, and herbicide concentration and quantities
used. These records will be included in all reporting documents.
Soil Restoration
After construction activities, the subsoil will be scarified and any compaction will be deep tilled before
the topsoil is placed back over the site. Any topsoil that is removed during construction will be
stockpiled and placed over the site during final soil preparation. This process should provide favorable
soil conditions for plant growth. Rapid establishment of vegetation will provide natural stabilization
for the site.

6.4 Mitigation Summary
Natural channel design techniques have been used to develop the restoration designs described in this
document. The combination of the analog and analytical design methods was determined to be
appropriate for this project because the watershed is rural, the causes of disturbance are known and
have been abated, and there are minimal infrastructure constraints. The original design parameters were
developed from the measured analog/reference reach data and applied to the subject stream. The
parameters were then analyzed and adjusted through an iterative process using analytical tools and
numerical simulations of fluvial processes. The designs presented in this report provide for the
restoration of natural Coastal sand -bed channel features and stream bed diversity to improve benthic
habitat. The proposed design will allow flows that exceed the design bankfull stage to spread out over
the floodplain, restoring wetland hydrology to the overbank areas.
A large portion of the existing stream will be filled using material excavated from the restoration
channel. However, many segments will be left partially filled to provide habitat diversity and flood
storage. Native woody material will be installed throughout the restored reach to reduce bank stress,
provide grade control, and increase habitat diversity.
Forested riparian buffers of at least fifty feet on both sides of the channel will be established along the
project reach. An appropriate riparian plant community will be established to include a diverse mix of
species. The plant species list has been developed and can be found in Table 14. Replanting of native
species will occur where the existing buffer is impacted during construction.
Due to the nature of the Project, complete avoidance of stream and wetland impacts is not possible.
Proposed stream impacts, including stream relocation and culverts, will be replaced on site. Wetland
impacts associated with restoration and enhancement efforts will only temporarily impact wetlands and
will provide an overall increase in wetland function with the addition of native trees and shrubs along
the stream banks, and restored hydrology. All stream and wetland impacts will be accounted for in the
Pre -Construction Notification (PCN) form.
6.5 Determination of Credits
Mitigation credits presented in Table 15 are projections based upon Project design (Figure 10). Upon
completion of Site construction, the project components and credits data will be revised to be consistent
with the as -built condition if there is a large discrepancy and with an approved mitigation plan
addendum. This will be approved by the USACE.

published in the October 2016 Wilmington District Stream and Wetland Compensatory Mitigation Update. A detailed
description of the methodology and calculations is described below and in Figure(s) 11.
6.6 Credit Calculations for Non -Standard Buffer Widths
Buffer measurements for additional credits were made horizontally, beginning from the edge of the
wetted perimeter and extending to easement boundary. Due to minimum require widths, additional
credit was not generated within the first 50 feet from the top of bank of stream channels. Table 16
describes the adjustments in stream credit based on buffer widths. Areas within the Site that are being
used to generate additional credit are solely being used for the generation of stream mitigation credits,
and will not be used for the generation of any other credit type (i.e., the same square foot of buffer
cannot be used to generate wetland credit, nutrient offset credits or state buffer credits). Area within a
buffer may only be used to provide credit for one stream (i.e., where buffers exist between two project
streams, these areas may only be counted toward credit for only one of the streams, and areas within
the minimum required buffer of any creditable stream may not be used for additional credit for any
other stream).
6.7 Credit Calculations for Macroinvertebrate and Water Quality Monitoring
Although water quality and macroinvertebrate monitoring is not required, this project will be monitor
both in accordance with the protocols specified in the 2016 Wilmington District Stream and Wetland
Compensatory Mitigation Update in order to generate an additional two percent credit. Credit will be
generated on all reaches since not only the restoration and enhancement treatments are expected to have
habitat uplift but also the preservation reaches due to the restoration and enhancement treatments
occurring upstream.

In order to calculate credit adjustments, the Wilmington District Stream Buffer Credit Calculator from
the USACE in January 2018 was utilized. To perform this calculation GIS analysis was performed to
determine the area (in square feet) of ideal buffer zones and actual buffer zones around all streams
within the project. Minimum standard buffer widths are measured from the top of bank (50 feet in
Piedmont and Coastal Plain counties or 30 feet in mountain counties) and are not included in the ideal
and actual buffer calculations. The ideal buffers are the maximum potential size (in square feet) of each
buffer zone measured around all creditable stream reaches, calculated using GIS, including areas
outside of the easement. The actual buffer is the square feet in each buffer zone, as measured by GIS,
excluding non -forested areas, all other credit type (e.g., wetland, nutrient offset, buffer), easement
exceptions, open water, areas failing to meet the vegetation performance standard, etc. Additional credit
is given to 150 feet in buffer width, so areas within the easement that are more than 150 feet from
creditable streams should were not included in this measurement. Non -creditable stream reaches within
the easement are removed prior to calculating this area with GIS (for both ideal and actual). The stream
lengths, mitigation type, ideal buffer, and actual buffer are all entered into the calculator. This is data
is processed, and the resulting credit amounts are totaled for the whole project (Table 15, Figure 11a
and 11b).

7 PERFORMANCE STANDARDS
The success criteria for the Site will follow accepted and approved success criteria presented in the
2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation Update and
subsequent agency guidance. Specific success criteria components are presented below.
7.1 Stream Restoration Success Criteria
Bankfull Events
Four bankfull flow events must be documented within the seven-year monitoring period. The four
bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four
bankfull events have been documented in separate years. Channel stability should be demonstrated
through a minimum of four bankfull events documented in the seven-year monitoring period.
Cross Sections
There should be little change in as -built cross sections. If changes do take place, they should be
evaluated to determine if they represent a movement toward a less stable condition (for example down -
cutting or erosion), or are minor changes that represent an increase in stability (for example settling,
vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross sections shall
be classified using the Rosgen stream classification method, and all monitored cross sections should
fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio
shall not exceed 1.2, and the entrenchment ratio shall be no less than 1.4 within restored reaches.
Channel stability should be demonstrated through a minimum of four bankfull events documented in
the seven-year monitoring period.
Digital Image Stations
Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion,
success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images
should not indicate the absence of developing bars within the channel or an excessive increase in
channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the
banks over time. A series of images over time should indicate successional maturation of riparian
vegetation.
Surface Flow
The stream restoration reach will be monitored to document intermittent or seasonal surface flow. This
will be accomplished through direct observation and the use of stream gauge transducers with data
loggers. Reaches must demonstrate a minimum of 30 consecutive days of flow.
7.2 Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the site will
follow IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover
a minimum of two percent of the planted area. Vegetation monitoring will occur annually between July
15 and leaf drop. The interim measures of vegetative success for the site will be the survival of at least
320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees that are at least 7
feet tall at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an
average height of ten feet at the end of Year 7. Volunteer trees will be counted, identified to species,
and included in the yearly monitoring reports, but will not be counted towards the success criteria of
total planted stems. Additionally, no species may account for over 50% of total stems at a given plot.
Uzzle Mitigation Plan 39 June 2018

8 MONITORING PLAN
Annual monitoring data will be reported using the IRT monitoring template. A detailed monitoring plan
is provided in Figure 12. The monitoring report shall provide a project data chronology that will
facilitate an understanding of project status and trends, research purposes, and assist in decision making
regarding project close-out. Monitoring reports will be prepared annually and submitted to the USACE.
Monitoring of the Site will adhere to metrics and performance standards established by the USACE's
April 2003 Wilmington District Stream Mitigation Guidelines and the NC IRT's October 2016
Wilmington District Stream and Wetland Compensatory Mitigation Update. Table 17 outlines the links
between project goals, objectives, and treatments and their associated monitoring metrics and
performance standards within the context of functional uplift based on the Stream Functions Pyramid
Framework.
8.1 As -Built Survey
An as -built survey will be conducted following construction to document channel size, condition, and
location. The survey will include a complete profile of thalweg, water surface, bankfull, and top of bank
to compare with future geomorphic data. Longitudinal profiles will not be required in annual
monitoring reports unless requested by USACE. Stream channel stationing will be marked with stakes
placed near the top of bank every 200 feet.
8.2 Visual Monitoring
Visual monitoring of all mitigation areas will be conducted a minimum of twice per monitoring year
by qualified individuals. The visual assessments will include vegetation density, vigor, invasive species,
and easement encroachments. Visual assessments of stream stability will include a complete
streamwalk and structure inspection. Digital images will be taken at fixed representative locations to
record each monitoring event, as well as any noted problem areas or areas of concern. Results of visual
monitoring will be presented in a plan view exhibit with a brief description of problem areas and digital
images. Photographs will be used to subjectively evaluate channel aggradation or degradation, bank
erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal
photos should indicate the absence of developing bars within the channel or an excessive increase in
channel depth. Lateral photos should not indicate excessive erosion or continuing degradation of the
banks over time. A series of photos over time should indicate successional maturation of riparian
vegetation.
8.3 Hydrology Events
Crest gauges will be installed to document the occurrence of bankfull events. A minimum of one gauge
will be installed. Crest gauges and/or pressure transducers will be installed on site to monitor surface
water hydrology For at least 30 days of flow each year. The devices will be inspected on a semiannual
basis to document the occurrence of bankfull events. Groundwater monitoring gauges with data
recording devices will be installed on site; the data will be downloaded on a quarterly basis during the
growing season.
8.4 Cross Sections
Permanent cross-sections will be installed at a minimum of one per 20 bankfull widths with half in
pools and half in shallows within the restoration area. Additional cross-sections will be installed at a
minimum of one per 50 bankfull widths along enhancement reaches to monitor stability as a result of
upstream restoration. All cross-section measurements will include bank height ratio and entrenchment
ratio. Cross-sections will be monitored in years 1, 2, 3, 5, and 7. There should be little change in as -
built cross-sections. If changes do take place, they should be evaluated to determine if they represent
Uzzle Mitigation Plan 40 June 2018
Project #000230

movement toward a less stable condition (for example down -cutting or erosion), or are minor changes
that represent an increase in stability (for example settling, vegetative changes, deposition along the
banks, or decrease in width/depth ratio).
8.5 Vegetation Monitoring
Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum of two
percent of the planted area. There will be 3 plots within the planted area (3.6 acres). Planted area
indicates all area in the easement that will be planted with trees. Existing wooded areas are not included
in the planted area. A combination of permanent fixed plots and random plots will be used to
demonstrate vegetation cover. Random plots will not make up more than 50% of the required plots.
The following data will be recorded for all trees in the plots: species, height, planting date (or
volunteer), and grid location. Monitoring will occur on years 1,2,3,5,7. Invasive and noxious species
will be monitored and treated so that none become dominant or alter the desired community structure
of the site. If necessary, RES will develop a species-specific control plan.
8.6 Water Quality
Sampling will be conducted prior to construction and for the duration of the monitoring period using a
continuous recording sampling device, and will include measurements of acidity (pH), temperature,
dissolved oxygen, and conductivity. Sampling points will be located as close as possible to the upper
and lower end of tributaries in order to detect any changes. Points will be located where water is freely
flowing and with sufficient depth to be conducted without disturbance to streambed sediments.
8.7 Macroinvertebrates
Sampling will be conducted prior to construction and once a year during monitoring years 3, 5, and 7.
Sampling points will be located on riffles, with the first sampling point located on the most downstream
riffle on the tributary. Appropriate sampling locations will be based on riffle condition and best
professional judgement. Pre -construction sampling may occur in different locations than those outlined
in the monitoring period, but sampling conducted during the monitoring period will occur within the
same riffle year-to-year, when possible. A reference location will also be sampled for comparison
purposes, located on a relatively stable reach in an undisturbed setting, located as close to the mitigation
site as possible, and within the same watershed.
The sampling will be conducted in accordance with the NCDWR Qual 4 macroinvertebrate sampling
protocol, which is described in the most current version of the Standard Operating Procedures for
Collection and Analysis of Benthic Macroinvertebrates, February 2016 (Version 5.0). If the stream is
large (greater than a 3 -square mile watershed), a mix of Qual 4 and the Standard Qualitative (Full Scale)
methods may be appropriate. Sampling will be conducted during the same time of year to minimize
seasonal differences in the data from year-to-year. Additionally, sampling will be conducted at the same
time as water quality monitoring, and within the index period referenced in the North Carolina Division
of Water Resources (NCDWR) document entitled Small Streams Biocriteria Development, dated May
29, 2009. Macroinvertebrate samples will be identified to the lowest practical taxonomic level (usually
Genus) by a qualified taxonomist (this qualification can be demonstrated by being a NCDWR certified
laboratory for macroinvertebrates). Results presented will include a list of taxa collected at each site
for each sampling event, as well as an enumeration of the Ephemeroptera, Plecoptera, and Trichoptera
(EPT) taxa and a Biotic Index (see the NCDWR Standard Operating Procedures for Collection and
Analysis of Benthic Macroinvertebrates). Each report should include a summary of the current results
and all past monitoring events in tabular format.
Uzzle Mitigation Plan 41 June 2018
Project #000230

8.8 Scheduling/Reporting
A mitigation plan and as -built drawings documenting stream restoration activities will be developed
within 60 days of the planting completion on the Site. The report will include all information required
by IRT mitigation plan guidelines, including elevations, photographs and sampling plot locations,
gauge locations, and a description of initial species composition by community type. The report will
also include a list of the species planted and the associated densities. Baseline vegetation monitoring
will include species, height, date of planting, and grid location of each stem. The baseline report will
follow USACE guidelines.
The monitoring program will be implemented to document system development and progress toward
achieving the success criteria. The restored stream morphology will be assessed to determine the
success of the mitigation. The monitoring program will be undertaken for seven years or until the final
success criteria are achieved, whichever is longer.
Monitoring reports will be prepared in the fall of each year of monitoring and submitted to the IRT.
The monitoring reports will include all information, and be in the format required by USACE.

Upon completion of Site construction, RES will implement the post -construction monitoring protocols
previously defined in this document. Site maintenance will be performed as described previously in
this document. If, during the course of annual monitoring, it is determined that the Site's ability to
achieve performance standards are jeopardized, RES will notify the USACE of the need to develop a
Plan of Corrective Action. Once the Corrective Action Plan is prepared and finalized RES 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.

Upon approval of the Site by the IRT, the Site will be transferred to the NCWHF:
North Carolina Wildlife Habitat Foundation
[phone]
PO Box 29187
Greensboro, NC 27429
www.ncwhf.oriz
The NCWHF will 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. Easements held by the
NCWHF are stewarded in general accordance with the guidelines published by the National Land Trust
Alliance. These guidelines include annual monitoring visits to easements and related communication
with the landowner(s). During the visit, a standard report is completed and pictures taken for the record.
If the Site is found to be in violation of the easement terms NCWHF works with the landowner to see
the problem rectified. When appropriate NCWHF pursues legal action to enforce the easement terms.
NCWHF typically requires the site developer to install standard NCWHF signage as part of the
easement transfer package. This includes well marked corners of the easement boundary, as well as
plastic or metal signs identifying the easement. The current sign standard is a 6"x6" aluminum sign
with contact information. Signs are refreshed on an as needed basis. Typically, a sign will last 5-10
years before it is no longer legible due to sun fading. An overview of the NCWHF Easement
Stewardship program will be included in Appendix C upon execution of the final easement agreement.
NCWHF requires and endowment for each easement it agrees to hold. All endowments are held
together in an investment fund. Endowments are sized so that the interest from the principal will pay
the expected monitoring costs for that easement. This assumes a seven-year monitoring period for the
site during which NCWHF will not incur any expenses. It also assumes a 5% annual return. Currently
NCWHF employs a contractor to handle annual monitoring visits and basic easement stewardship. This
flat fee includes a property walkthrough, report, pictures, sign installation, etc. The endowment fee has
not yet been confirmed for the easement transfer of the Uzzle Site, and it will be updated once finalized.

11 CREDIT RELEASE SCHEDULE
All credit releases will be based on the total credit generated as reported in the approved mitigation
plan of the Site. Under no circumstances shall any mitigation project be debited until the necessary DA
authorization has been received for its construction or the District Engineer (DE) has otherwise
provided written approval for the project in the case where no DA authorization is required for
construction of the mitigation project. The DE, in consultation with the 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 in Table 18.
11.1 Initial Allocation of Released Credits
The initial allocation of released credits, as specified in the mitigation plan can be released by the IRT
with written approval of the DE upon satisfactory completion of the following activities:
a) Execution of the UMBI by the Sponsor and the USACE
b) Approval of the final mitigation plan
c) Mitigation site must be secured
d) Delivery of financial assurances.
e) Recordation of the long-term protection mechanism and title opinion acceptable to the USACE
f) Issuance of the 404 permit verification for construction of the site, if required.
11.2 Subsequent Credit Releases
The second credit release will occur after the completion of implementation of the Mitigation Plan and
IRT approval of the Baseline Monitoring Report and As -built Survey. 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. As projects approach milestones associated with credit
release, the Sponsor 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.

Project #000230

12 MAINTENANCE PLAN
The Site will be monitored on a regular basis and a physical inspection will be conducted 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:
Table 19. Maintenance Plan
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. Stream
maintenance activities will be documented and reported in annual monitoring
re orts. Stream maintenance will continue through the monitoring period.
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. Vegetation
maintenance activities will be documented and reported in annual monitoring
re orts. Ve etation maintenance will continue through the monitoring period.
Site Boundary
Site boundaries shall be identified in the field to ensure clear distinction between
the mitigation site and adjacent properties. Boundaries will be marked with signs
identifying the property as a mitigation site, and will include the name of the long-
term steward and a contact number. 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. Easement
monitoring and staking/signage maintenance will continue in perpetuity as a
stewardshi activity.
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. Crossings in easement breaks are the responsibility of the landowner
to maintain.
Livestock Fencing
Livestock Fencing is to be placed outside the easement limits. Maintenance of
fencing is the responsibility of the landowner.
Beaver
Routine site visits and monitoring will be used to determine if beaver management
is needed. If beaver activity poses a threat to project stability or vegetative
success, RES will trap beavers and remove impoundments as needed. All beaver
management activities will be documented and included in annual monitoring
reports. Beaver monitoring and management will continue through the monitoring
period.

Project #000230

13 FINANCIAL ASSURANCES
CONFIDENTIAL
The Sponsor will provide financial assurances in the form of a $416,500 Construction Performance
Bond to the USACE to assure completion of mitigation construction and planting. Construction and
planting costs are estimated to be at or below $416,500 based on the Engineer's construction materials
estimate and recent bid tabulation unit costs for construction materials. Following completion of
construction and planting the Construction Performance Bond will be retired and a $206,650
Monitoring Performance Bond will be provided to assure completion of seven years of monitoring and
reporting, and any remedial work required during the monitoring period. The $206,650 amount includes
contingency and estimated monitoring costs from the Engineer. The Monitoring Performance Bond
will be reduced by $37,000 following approval of each annual monitoring report. The Monitoring
Performance Bond will be retired in total following official notice of site close-out from the IRT.
Financial assurances shall be payable to a standby trust or other designee at the direction of the obligee.
Financial assurances structured to provide funds to the USACE in the event of default by the Bank
Sponsor are not acceptable. A financial assurance must be in the form that ensures that the USACE
receives notification at least 120 days in advance of any termination or revocation. The Performance
Bonds will be provided by a surety listed with the U.S. Treasury and has an A.M. Best Rating of B or
above. All Performance Bonds will be submitted to the USACE in draft form for approval prior to
execution. In the event of Sponsor default, UP2S has agreed to receive the funds and ensure the work
is successfully completed.

Site Protection Instrument

SITE PROTECTION INSTRUMENT
The land required for the construction, management, and stewardship of this Site includes portions of
the following parcels (Table 1).
Table 1. Project Parcel and Landowner Information
The Wilmington District Conservation Easement model template was utilized to draft the site protection
instrument. Once finalized, a copy of the final recorded easement will be provided in Appendix A.
EBX-Neuse I, LLC, acting as the Bank Sponsor, will establish a Conservation Easement, and will
monitor the Site for a minimum of seven years. This Mitigation Plan provides detailed information
regarding bank operation, including long term management and annual monitoring activities, for review
and approval by the Interagency Review Team (IRT). Upon approval of the Site by the IRT, the Site
will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will 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 will be negotiated prior to site transfer to the responsible party.
The Bank Sponsor will ensure that the Conservation Easement will allow for the implementation of an
initial monitoring phase, which will be developed during the design phase and conducted by the Bank
Sponsor. The Conservation Easement will allow for yearly monitoring and, if necessary, maintenance
of the Site during the initial monitoring phase. These activities will be conducted in accordance with
the terms and conditions of the approved Mitigation Plan for the Uzzle Mitigation Site. The Uzzle Site
will be authorized under the Neu -Con Wetland and Stream Umbrella Mitigation Bank made and entered
into by EBX-Neuse I, LLC, US Army Corps of Engineers, and NC Division of Water Resources.

Dear Ms. Conder,
ROY COOPER
col, <„
WILLIAM G. ROSS. JR.
S. JAY ZIMMERMAN
On December 28, 2016, Katie Merritt, with the Division of Water Resources (DWR), received a
request from Resource Environmental Solutions, LLC (RES), for a site visit near the above -
referenced site in the 8 -digit Hydrologic Unit Code 03020201 of the Neuse River Basin to determine
the potential for riparian buffer mitigation and nutrient offset. On January 13, 2017, Ms. Merritt
performed a site assessment of the subject site, which is more accurately shown in the attached aerial
initialed by Ms. Merritt on January 13, 2017.
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. The evaluation was made from Top of Bank (TOB)
out to 200' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295 (effective
November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0240.

A map showing the project site and the features was provided by RES and was initialed by Ms.
Merritt on January 13, 2017. This letter should be provided in all future stream, wetland or buffer
mitigation plans for this Site.
This letter does not constitute an approval of this site to generate mitigation credits. Pursuant to 15A
NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DWR for written
approval prior to conducting any mitigation activities in riparian areas and/or surface waters.
Pursuant to 15A NCAC 02B .0240, a proposal regarding a proposed nutrient load -reducing measure
shall be submitted to DWR for approval prior to any mitigation activities in riparian areas and/or
surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to
be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being
viable for nutrient offset credit above, one could propose a different measure, along with supporting
calculations and sufficient detail to support estimates of load reduction, for review by the DWR to
determine viability for nutrient offset according to 15A NCAC 02B .0240.
Please contact Katie Merritt at (919)-807-6371 if you have any questions regarding this
correspondence.

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
"pre -construction notification" (PCN), or requests verification for a non -reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant's acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.

This preliminary JD finds that there "maybe" waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:

S. JAY /IMMFRMAN
On December 28, 2016, Katie Merritt, with the Division of Water Resources (DWR), received a
request from Resource Environmental Solutions, LLC (RES), for a site visit near the above -
referenced site in the 8 -digit Hydrologic Unit Code 03020201 of the Neuse River Basin to determine
the potential for riparian buffer mitigation and nutrient offset. On January 13, 2017, Ms. Merritt
performed a site assessment of the subject site, which is more accurately shown in the attached aerial
initialed by Ms. Merritt on January 13, 2017.
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. The evaluation was made from Top of Bank (TOB)
out to 204' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295 (effective
November 1, 2415) and for nutrient offset credits pursuant to 15A NCAC 02B .0240.

Uzzle Site (RES)
January I3, 2017
A reap showing the project site and the features was provided by RES and was initialed by Ms.
Merritt on January 13, 2017. This letter should be provided in all future stream, wetland or buffer
mitigation plans for this Site.
This Ietter does not constitute an approval of this site to generate mitigation credits. Pursuant to 15A
NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DWR for written
approval prior to conducting any mitigation activities in riparian areas and/or surface waters.
Pursuant to 15A NCAC 028 .0240, a proposal regarding a proposed nutrient load -reducing measure
shall be submitted to DWR for approval prior to any mitigation activities in riparian areas and/or
surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to
be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being
viable for nutrient offset credit above, one could propose a different measure, along with supporting
calculations and sufficient detail to support estimates of load reduction, for review by the DWR to
determine viability for nutrient offset according to 15A NCAC 02B .0240.
Please contact Katie Merritt at (919)-807-6371 if you have any questions regarding this
correspondence.
Sincerely.

Appendix F
Invasive Species Plan

INVASIVE SPECIES PLAN
During existing site conditions analysis, RES will perform an invasive species survey as part of the existing
vegetation community survey within the Site easement. Common species that personnel will be trained to
identify upon encountering include, but are not limited to, multiflora rose (Rosa multiflora), Chinese privet
(Ligustrum sinense), tree -of -heaven (Ailanthus altissima), mimosa tree (Albizia julibrissin), kudzu
(Pueraria spp.), oriental bittersweet (Celastrus orbiculatus), Japanese knotweed (Fallopia japonica),
autumn olive (Elaeagnus umbellata), princess tree (Paulownia tomentosa), Chinaberry (Melia azedarach),
Porcelain -berry (Ampelopsis brevipedunculata), English ivy (Hedera helix), and Chinese wisteria (Wisteria
sinensis).
If required to meet monitoring standards, invasive species within the project easement will be identified
and treated to promote the growth and establishment of native species that match the target habitat type of
the restoration project. Treatment of invasive species may include mechanical removal via cutting and/or
mowing or a combination of mechanical removal and herbicide application to minimize presence in the
project easement. All herbicide application will be conducted in accordance with the North Carolina
Department of Agriculture & Consumer Services (NCDA&CS) rules and regulations by trained and
licensed applicators. If areas of invasive species exist within the easement, they will be monitored yearly
as part of the monitoring protocol, and treated if necessary. If required, problem areas will continue to be
treated until the project easement shows overall trending towards meeting all monitoring requirements.

Subject: Action ID # 2016-01973; Modification of the Neu -Con Umbrella Mitigation Banking Instrument
associated with the addition of the Uzzle Mitigation Site
Dear Mr. Thomas:
The U.S. Fish and Wildlife Service (Service) has reviewed the information concerning the above
referenced project. The project, based on the description in your letter to our office, the provided
Instrument Modification,, and other, information, 19 expectedlo have minimal adverse impacts to:
fish and wildlife -resources:.,
The proposed Uzzle:Mitigation Site is approximately 26 -acres; anddoccurs sodth of U.S. .
Highway 70 and:west of Meta Drive,: southeast of Clayton and includes Little Poplar Creek, in
Johnston County; North Carolina. The project proposes to; restore 944 linear fee€ (LF) of stream
channel and to enhance 4,209 LF of Little Poplar Creek; and to enhance 701 LF of two unnamed
tributaries, all of which will be included within the conservation easement onsite.
We do not have any major concerns with the Uzzle Mitigation Site plan as currently proposed,
and think this project could greatly benefit the downstream water quality. Downstream water
quality in this watershed is greatly important to the Service since there have been records of the
following aquatic federal species of concern (FSC) in the recent years: Roanoke. slabshell
(E'll ptio roanot ensis) found in 2015, It floater (Aldstnicicnta tnduldta) found in 2012, and
the State threatened Eastern lampmussel (Lampsillis radiata) found in 2005. There have also
been records of the Neuse River Waterdog (Necturis lewisi), also a federal species of concern,
found downstream. The Service encourages mitigation efforts in priority watersheds, or with
work that drains to priority watersheds such as this one, that will benefit federal and state listed
species. We will continue to be involved in this project through discussions with the IRT, and
will provide additional comments in the future if warranted.
The Service has reviewed available information on federally -threatened or endangered species
known to occur in Johnson County; specifically within the proposed mitigation work area, and
downstream in the Little Poplar Creek tributaries and the larger Neuse River. Federally listed
species in Johnston County, North Carolina include: Red -cockaded woodpecker (Picoides
borealis), Tar River spinymussel (Eliptio sleinstansana), dwarf wedgemussel (Alasmidonla
heterodon), and Michaux's sumac (Rhus michauxii), in addition to many' other federal species of

2
concern. We have also reviewed information from the North Carolina Natural Heritage Program
(NCNHP) database which contains excellent data on the special status species, both federal and
state, which can be found here: https://nenlide.natureserve.org/. On page 6, the species list
mentions that one Natural Heritage Data element occurrence was found to be within one -mile of
the project, but the species is not mentioned in the Mitigation Site plan. Please define that
species in future plans for consistency. Our review indicates that no federally listed species
under Service jurisdiction are likely to occur in the project area due to lack of appropriate
habitat. Therefore, the Service would concur with a determination that the action is not likely to
adversely affect species designated as threatened, endangered, or their designated critical habitat.
In accordance with the Endangered Species Act of 1973, as amended, (ESA) and based on the
information provided, and other available information, it appears the actions described in the
Mitigation Site plan for the Uzzie Mitigation Site are not likely to adversely affect federally
listed species or their critical habitat as defined by the ESA. We believe that the requirements of
Section 7 (a)(2) of the ESA have been satisfied for this project. Please remember that
obligations under the ESA must be reconsidered if: (1) new information identifies impacts of this
action that may affect listed species or critical habitat in a manner not previously considered; (2)
this action is modified in a manner that was not considered in this review; or, (3) a new species is
listed or critical habitat determined that may be affected by the identified action.
The Service appreciates the opportunity to comment on this Mitigation Site plan. If you have
questions regarding these comments, please contact Emily Wells at 919-856-4520, ext. 25 or by
e-mail at < [e-mail] >.
