Re: Neu-Con MBI / Nahunta Swamp Site Specific Wetland and Stream - Phase 11
401/404 Pre-Construction Notification Application
Dear Mr. Bell and Mr. Hennessy:
Enclosed for your consideration and approval is the Pre-Construction Notification for the Corps nationwide
permit 27 and the Division of Water Quality's general certification 3399 for Wetland and Riparian
Restoration and Creation for our Nahunta Swamp wetland and stream mitigation project. Also enclosed are
copies of the revised Nahunta Swamp Site-Specific Wetland and Stream Mitigation Plan for your reference
in reviewing the PCN application. Please note that we have requested expedited review of this application to
enable site preparation to take place during July and August so that the wetland plant species may be planted
during the appropriate dormant season at the end of this year. Thank you in advance for your assistance.
The Nahunta Swamp Site was broken up into two phases. The first phase involved restoration of 43.5 acres
of riparian wetlands. This phase was implemented during February 2004 in order to have Phase I completed
before the start of the 2004 growing season. A secondary reason for the two phases was to use the wetland
sites for Phase I as a benchmark for Phase 11; the design for Phase II could be tweaked if necessary based on
the construction and success of Phase 1. Phase I did not involve impacts to jurisdictional waters of the US,
therefore only a Sediment and Erosion Control permit was required and obtained. Phase II involves stream
restoration in addition to wetland restoration. Therefore, the enclosed PCN and request for 401/404
certification are being submitted for Phase II only.
If I can be of any further assistance, please do not hesitate to contact me at [phone].
Very truly yours,

Proposed impacts are required to restore wetland hydrology and stream functions, as
described in The Nahunta Swamp Wetland and Stream Mitigation Plan. Proiect will result
in the restoration of approximately 73 acres of prior-converted farm fields to wetland, and
an overall increase in stream len th on the site from 5,113 feet to 10,820 feet.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http: //h2o. enr. state. nc.us/ncwetlands/strmp,ide.htinl.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

Executive Summary
The Nahunta Swamp wetland and stream mitigation site is located in Wayne
County, North Carolina approximately eight miles northeast of the Town of Goldsboro.
All project properties are located adjacent to Nahunta Swamp. Numerous ditches exist
across the properties and were used to promote drainage when the land was under
agricultural production. These ditches collect shallow subsurface drainage and discharge
to Nahunta Swamp. The entire project site is approximately 249 acres is size, with
approximately 126 acres of prior-converted cropland.
Land-use for the mitigation site over the past 50 to 60 years has been row crop
agriculture. However, the riparian areas located around the perimeter of the site contain
desirable native vegetation, including water oak (Quercus nigra), overcup oak (Quercus
lyrata), and river birch (Betula nigra). The shrub layer is dominated by giant cane
(Arundinaria gigantea), and southern arrowwood (Viburnum dentatum). The herb and
vine strata consists of pokeweed (Phytolacca americana), dog-fennel (Eupatorium
capillifolium), aster (Aster spp.), royal fern (Osmunda regalis), blackberry (Rubus spp.),
green-briar (Smilax spp.), and honeysuckle (Lonicera japonica). Therefore, the potential
for restoration of a diverse community of native vegetation exists due to the close
proximity of appropriate seed sources.
Monitoring data collected from February 2002 through February 2003 indicate the
site currently exhibits hydrologic conditions drier than wetland conditions. The ditches on
the site transport surface and shallow subsurface drainage from the site, in effect lowering
the water table and keeping soil conditions favorable for agricultural production.
Examination of the available hydrology and soil data indicate that the site has good
potential for the restoration of a productive wetland and stream ecosystem.
The targeted restoration communities will include the "Coastal Plain small stream
swamp," and "non-riverine hardwood forest" communities, as described by Schafale and
Weakley (1990). Due to the productivity and accessibility of these systems, most have
experienced heavy human disturbance. Restoration will involve raising the bottom
elevation and re-establishing a normal pattern on six of the tributaries draining into
Nahunta Swamp. These measures will raise the local water table and restore wetland and
stream hydrology on the mitigation sites. In addition, scarification of the fields and
breaking of the local plow pan will provide increased surface storage of water and
provide a range of conditions for a variety of native wetland plant species. No
modifications will be made to the main channel of Nahunta Swamp, as any increases in
stream bottom elevation could pose potential flooding concerns, not only for the
restoration site, but also for property owners upstream. The total area of restored
wetlands will be approximately 117 acres, with approximately 33.5 acres of wetland
preservation. The proposed designs will also result in 10,822 feet of stream restoration.

I Introduction
1.1 Project Description
The Nahunta Swamp wetland and stream mitigation site is located in northeast
Wayne County, North Carolina, approximately eight miles northeast of the Town of
Goldsboro (see Figure 1-1). The site has a past history of agricultural use, consisting
primarily of row crop agriculture and some smaller areas of pasture land. There are
several small, channelized tributaries that drain through the project properties to Nahunta
Swamp. There are also numerous field ditches that provide additional drainage. The
entire site is approximately 249 acres in size, with approximately 126 acres of prior-
converted farm fields.
Environmental Banc and Exchange (EBX), LLC proposes to restore wetland and
stream functionality to the site for the purpose of fulfilling mitigation requirements for
the North Carolina Department of Transportation (NCDOT). The project properties have
been divided into tracts for ease of presentation and discussion in this report (see Figures
2 through 2-5). The characteristics of each tract are discussed in Section 2 of this report,
and proposed restoration plans are discussed in Section 3.
1.2 Study Area
The Nahunta Swamp mitigation site is located in the Coastal Plain Physiographic
Region near the Towns of Goldsboro and Fremont, North Carolina. The proposed
wetland and stream restoration areas are located on the historic floodplain of Nahunta
Swamp. The site is located within eight digit hydrologic unit code (HUC) 03020203. The
tributaries targeted for restoration originate on the higher ground and interstream divide
areas and discharge to Nahunta Swamp after flowing across its floodplain. All of these
tributaries have been channelized in the past to provide drainage to the surrounding
agricultural fields. All properties targeted for restoration are classified as prior converted
(PC) cropland by the Natural Resources Conservation Service (MRCS).

2.1 Introduction to Project Tracts
Due to the large land area encompassed by the project, the number of streams, and
the complexity of the project, the project properties have been divided into five (5)
project tracts for ease of presentation and discussion in this report. The existing
conditions of each tract, including soils, hydrology, stream assessments, and existing
wetlands, will be discussed in this section of the report. The locations of each tract are
shown in Figures 2 through 2-5, and a summary of existing conditions is provided in
Table 2-1 below.

2.2 General Geology and Soils
The project site is located in the Coastal Plain of North Carolina along the
floodplain of Nahunta Swamp. The underlying geology of the site is mainly sedimentary
rock of the undivided Yorktown and Duplin Formations. The Yorktown Formation is
composed of fossiliferous clay and sand, while the Duplin Formation is composed of
shelly sand, sandy marl, and limestone (NCGS, 1991). Bore hole tests were conducted
during the spring of 2001 to verify soil information obtained from the Wayne County soil
survey (a formal confirmation of hydric soils was conducted by Wetland and Natural
Resource Consultants Inc., WRNC). The test holes were dug primarily in low lying areas
where most restoration activities will occur. Although there was some variation between
test-hole profiles and soil survey descriptions, all test holes indicated presence of hydric
soils with a depleted matrix in the A and/or B horizons of the soil profile. Surface layers
to a depth of 2 to 3 feet typically exhibited matrix values of 4 or less and chromas of 2 or
less. Most profiles consisted of a sandy clay loam textured surface layer, changing to
sandy loam textures in the subsurface horizons. Typically, at a depth of approximately 5
feet, a layer of saturated sand to sandy loam textured sediments was found at most
locations; however, this layer was found to be shallower in several locations. Augered
holes were also used to measure saturated hydraulic conductivity using the method
described by van Beers (1970). Saturated hydraulic conductivity measurements were
conducted and the collected data were used as inputs for hydrologic models. Typical
conductivities across the site ranged from approximately 4 to 20 cm/hr, although higher
conductivities were recorded in areas where test holes penetrated a sand layer.
2.3 Climatic Conditions
Wayne County, North Carolina has an average annual rainfall of 49.8 inches
(NRCS WETS Tables NC3510 for Goldsboro). In much of the Coastal Plain of North
Carolina, approximately 36 inches of water are lost to evapotranspiration during an
average year (Evans and Skaggs, 1985). Since average rainfall exceeds average
evapotranspiration losses, the Coastal Plain of North Carolina experiences a moisture
excess during most years, meaning that the excess water must leave a site by groundwater
flow, runoff, channelized surface flow, or deep seepage. Annual losses due to deep
seepage, or percolation of water to confined aquifer systems, are typically less than 1 inch
of water for most Coastal Plain areas and are not a significant loss pathway for excess
water. Although groundwater flow can be significant in some systems, most excess water
is lost via surface and shallow subsurface flow.
0 The growing season for Wayne County is 248 days long, beginning on March 10
• and ending November 13, as calculated from National Weather Service wetland
Determination Tables (WETS) for Goldsboro 4 SE, NC3510.
0 2.4 General Site Hydrology
r
The presence of hydric soils over much of the project site is evidence that the site
historically supported a wetland ecosystem. As is the case in much of the Coastal Plain of
North Carolina, local drainage patterns have been altered over the past two centuries to
Nahunta Wetland and Stream Mitigation Plan 2-8

• promote agricultural production. Historically, Nahunta Swamp was a large Coastal Plain
swamp system with numerous smaller tributaries and headwater swamps that fed into it.
Many years ago, a large canal was dug through the swamp to provide drainage and flood
control to the surrounding areas, so that the fertile hydric soils of the swamp could be
• developed for agriculture. Likewise, the smaller tributaries were also channelized and
additional ditching and topographic manipulations were used to provide the drainage
necessary to work the land. The Nahunta Swamp canal is classified as Class "C", nutrient
sensitive waters by the NC Division of Water Quality. The proposed project will reduce
• the input of nutrients to the system by restoring riparian buffers and wetlands, and by
• removing crop and pasture land directly adjacent to Nahunta Swamp from production.
A number of issues preclude restoring the Nahunta Swamp system to its condition
• prior to the influence of man. At the downstream end of the project site, the Nahunta
. Swamp canal has a drainage area of approximately 40 square miles. Therefore, any
attempts to restore the hydrology of the main canal would impact land miles upstream of
the project site and would lead to considerable hydrologic trespass and flooding issues.
• However, the potential exists to restore the functionality of certain drained areas by
• removing the current drainage practices and restoring the smaller tributaries that flow
through the site to a more natural condition. In this manner, the local water table will be
raised within the project boundaries without adversely affecting properties outside of the
project limits.
A total of 29 wells were installed across the project tracts for the purpose of
documenting site hydrology (locations are shown in Figures 2-1 through 2-5). Water
table data for manually read wells were collected from April 2002 through August 2002,
. while data from three automated wells were collected from February 2002 through
February 2003 to capture detailed data from one entire year at specific locations. Well
• data from the project site were analyzed to determine the current hydrologic state of the
site. Discussions about the specific site hydrology of each project tract are provided
within Sections 2.5 through 2.9. Wells installed across the site have been removed in
• preparation for construction activities. New wells will be installed during the post-
construction monitoring period, as described in Section 5.1 of this report.

Rainfall data were collected for the monitoring period to correlate climatic
• conditions with water table hydrology. Rainfall data were collected from the nearest
automated weather station, located in Goldsboro, North Carolina, approximately eight (8)
miles southwest of the project site (Goldsboro 4 SE, NC3510). Since the data from the
Goldsboro 4 SE station had significant amounts of data missing from July 2002 through
• February 2003, data for these months were provided by the Goldsboro ECONet station,
located approximately 12 miles southwest of the project site. Monthly precipitation
• amounts from February 2002 through February 2003 are compared with average monthly
rainfall in Table 2-2. These data indicate that much drier than average conditions were
• experienced at the project site during the monitoring period.

The data from the three automated wells on the site (Wells #17, #23, and #25) are
shown in Figure 2-6. As expected, the data indicate that a range of hydrologic conditions
exists across the Nahunta properties, with several noticeable trends. First, low water table
conditions are present over all the sites during the majority of the growing season.
Second, water table conditions can vary over a wide range of depths throughout the year,
with the highest water table during the dormant season and the lowest during the middle
of summer. The high water table conditions during the winter for Well #17 are due to the
presence of hillslope seepage on the Edmundson Tract, and are discussed in Section 2.7.

2.5 Cole Tract
The Cole Tract is the northernmost of the five tracts located on the mitigation
property (Figure 2-1). The Cole Tract is approximately 24.9 acres in size, with
approximately 6.3 acres of prior converted fields. This land was the historic floodplain of
Nahunta Swamp prior to channelization. The land is currently under row crop agriculture
production (corn) and is composed primarily of hydric soils. An unnamed tributary to
Nahunta Swamp, designated as Reach 1, flows along the northern boundary of the Cole
Tract for approximately 1,020 feet before its confluence with Nahunta Swamp.
2.5.1 Cole Tract Existing Soils
The Soil Survey for Wayne County (NCDA, 1991) classifies the cleared soils on
the Cole Tract as the Johnston (Js) series. Johnston soils are described as very poorly
drained soils found on flat, broad floodplains, formed in recent alluvium. The surface
layer is approximately 20 to 30 inches thick and is a dark gray loam. The subsoil extends
to a depth of nearly 50 inches and is grayish brown to gray sandy loam; the seasonal high
water table is at the ground surface. Johnston soils are listed as hydric by the NRCS
(USDA, 1995). Soil Survey information indicates that when artificially drained, as is the
case with the Cole tract, the soil is well suited for crop production. Within the mapped
area of Johnston soil, near the northwest corner of the cleared field, is a sand ridge that
does not match the description of the Johnston series. This area of non-hydric soil was
delineated as shown in Figure 2-1 and is approximately 0.6 acre in size. The sand ridge is
likely a remnant of alluvial deposits from Nahunta Swamp.
Nahunta Wetland and Stream Mitigation Plan 2-11 EBX / Buck Engineering
To the east of the site beyond the toe of the hillslope, soils are characterized as the
Lucy (Lu) and Norfolk (No) series. Lucy soils consist of well drained, nearly level to
gently sloping soils on smooth, slightly convex divides. The seasonal high water table
remains below 5 feet in depth. The surface layer is loamy sand about 24 inches thick that
is brown in the upper part and light yellowish brown in the lower part. The subsoil, to a
depth of about 70 inches, is friable sandy clay loam that is strong brown and yellowish
red in the upper part and red in the lower part. Norfolk soils consist of well drained,
nearly level to sloping soils on broad, smooth, slightly convex divides. The seasonal high
• water table remains below a depth of 5 feet. The surface layer is grayish brown and pale
brown loamy sand about 11 inches thick. The subsoil is about 64 inches thick and is
dominantly yellowish-brown and brownish-yellow, friable sandy clay loam.
• 2.5.2 Cole Tract Existing Stream
Reach 1 exists as an incised "C5" stream type, using the Rosgen Stream
S Classification Method (Rosgen, 1994), with bank height ratios ranging from 1.1 to 2.0
• and averaging 1.4. The "5" in the stream classification indicates that the stream bed is
• dominated by particles in the sand size fraction. Reach 1 appears to have been
channelized in the past, as the channel has a trapezoidal shape and there is minimal
pattern on the project property. There is potential for additional down-cutting since the
confluence with Nahunta Swamp has a drop of nearly 4 feet. Above the property line, the
• reach has developed a meandering pattern and as a result, exhibits well developed pool
and riffle sequences. Bank height ratios, in this section, are close to 1.0, indicating that
the stream is not incised and has access to the adjacent floodplain. The land adjacent to
this portion of the stream is forested and well buffered by vegetation. Within the project
• property, the stream was apparently channelized in the past to provide additional drainage
and reduce flooding of the property. As a result, Reach 1 suffers from a lack of bedform
diversity and moderate bank erosion along much of the project length. Geomorphical
stream parameters for Reach 1 are provided in Appendix 1.

2.5.3 Cole Tract Hydrology
Four (4) manually read groundwater monitoring wells were installed on the Cole
Tract during early April 2002 (see Figure 2-1 for well locations). Water level
observations were made on weekly to monthly intervals through July 2002. All well
installations and data collection were completed by WNRC, Inc. On the Cole Tract,
wells were placed in two transects of two wells each. The wells were installed
approximately 200 feet apart, perpendicular to Nahunta Swamp. Both transects on the site
indicate that the groundwater flows from the hill slope on the east side of the cleared field
to Nahunta Swamp, following the topographic gradient. During the early growing season,
water table depths across the field were generally in the range of 25 to 40 inches. During
the summer months, water table depths dropped to greater than 60 inches deep over
extended dry periods. Well data are provided in Figure 2-7 for the Cole Tract.
On the southern corner of the Cole Tract, where the property boundary and
Nahunta Swamp meet, there is a 4-inch diameter subsurface tile drain outlet. The extent
Nahunta Wetland and Stream Mitigation Plan 2-12
EBX / Buck Engineering
of the tile drainage on the field is unknown. Based on site topography, it is likely that the
drain and any lateral lines are confined to the lower southwestern corner of the field. This
corner of the field is concave in shape and as a result was likely a historically wet area.
The tile line allows for drainage of the corner without losing any usable land. On the
northern portion of the field, the channelized stream (Reach 1) provides surface and
subsurface drainage.

2.5.4 Cole Tract Existing Wetlands
There is an area of existing riparian wetlands approximately 5.0 acre in size that
exists along the northern wooded edge of the Cole Tract. A formal delineation of the area
will be performed prior to construction on the site to document the existing condition of
the wetland. The restored wetlands on the Cole Tract will connect to this area of existing
wetland, expanding the total acreage of wetlands on the site. Existing wetland areas
within the project limits will be protected with a conservation easement.
2.6 Tapp Tract
The Tapp Tract is located downstream along Nahunta Swamp from the Cole Tract
(Figure 2-2). Like all of the tracts described in this report, the Tapp Tract cleared fields
are located on the historic floodplain of Nahunta Swamp. Soils on this property are
primarily hydric, with the exception of the hill slope to the east, where areas of non-
hydric soils are present and several smaller pockets of non-hydric sand ridges within the
cleared fields. Project Reaches 2 and 4 flow along the northern and southern boundaries
of the Tapp Tract, respectively, while Reach 3 flows through the middle of the property.
The total area of the Tapp Tract is 63.2 acres, with approximately 18.2 acres of prior
converted fields.

r
2.6.1 Tapp Tract Existing Soils
• The Soil Survey indicates that Johnston (Js) soils, described in Section 2.5.1, and
• Weston (We) soils exist on the floodplain of Nahunta Swamp, with Bibb (Bb) soils
present along the toe slope areas in the northeast portion of the tract. On the higher
elevation hillslope areas, Norfolk (No) soils are present. Weston soils are described as
poorly drained, nearly level soils found on smooth flats and in depressions on upland
• terraces. Weston soils, like the Johnston soils, are formed in stream sediments. The
seasonal high water table for Weston soils is at the ground surface. Typically, the surface
layer is about 12 inches thick and is a gray to grayish brown loamy sand. The subsoil is a
sandy loam that is approximately 42 inches thick and is a light brownish gray. Bibb soils
• are described as poorly drained, nearly level soil situated on floodplains. This soil series,
• like the Johnston and Weston soils, are formed in recent alluvium. The surface layer is
dark grayish-brown sandy loam approximately 10 inches thick. The subsurface layer
extends to a depth of nearly 55 inches and is dark gray to gray sandy loam. The seasonal
• high water table is at the surface. Both the Bibb and Weston soil series are listed as
. hydric "A" list soils by the NRCS (USDA, 1995). The Norfolk soils series is described in
Section 2.5.1.

2.6.2 Tapp Tract Existinq Streams
Reach 2 is the northernmost reach on the Tapp tract and flows in a westerly
direction on the mitigation property for 1,178 feet before its confluence with Nahunta
Swamp. Reach 2 exists as an incised "G5/C5" Rosgen stream type on the project
property. In the "G5" portion of the stream, the bank height ratio is greater than 3
indicating that the stream does not have access to the floodplain except during extreme
high water events. Bank height ratios decrease somewhat as the stream flows to Nahunta
Swamp, such that the lower portion of the stream is classified as an incised "B5" or "C5"
stream type. This lower portion of the reach is channelized and degraded, with vertical
eroding streambanks and an overall lack of bedform diversity.
Upstream of the project property, Reach 2 exists as an "ES" stream type that is not
incised and displays a natural stream pattern. After the reach flows onto the project
property, there is an abrupt drop in streambed elevation. It appears that the stream
through the property was channelized in the past, up to a point where the gradient of the
hillslope increases. At this location, the channelization was stopped. This point of
dramatic change in stream gradient caused a headcut that has now migrated up through
the stream. The headcut is now located near the northeast corner of the site, and at this
location there is a dramatic 3 foot drop in stream bed elevation and a large scour pool.
Reach 3 originates in a forested area before flowing through the agricultural fields
on the mitigation property. From the point where Reach 3 flows into the open agricultural
fields, the stream flows approximately 568 feet in a southwesterly direction to its
confluence with Nahunta Swamp. Within the open field area and for a distance into the
woods upstream, Reach 3 exists as an incised "B5" Rosgen stream type. Incision and
Nahunta Wetland and Stream Mitigation Plan 2-14
EBX / Buck Engineering
• bank height ratios increase as the stream flows toward its confluence with Nahunta
Swamp. Currently on the project property, the stream has little or no pattern, due to the
apparent channelization used to improve drainage and increase the farmable area for
• agricultural production. The stream exhibits features typical of agricultural ditching: a
• trapezoidal shape and deep banks with steep slopes. The existing stream has few bed
features due to the lack of pattern. The stream bed is dominated by particles in the sand
size fraction. The change in Rosgen stream type can be explained by the increase in
valley slope on the project property, as well as the elevation change needed for Reach 3
• to flow into Nahunta Swamp at their confluence. Near its confluence with Nahunta
Swamp, the channel has widened over time to the point that the stream is beginning to
form a floodplain at a lower elevation within the widened, incised channel. Bank
instability is still high in this area as the extremely high banks continue to slump and
• erode in an attempt to reach stability over the long term.
Reach 4, the southern most reach on the Tapp Tract, originates in a forested area
east of the project property before flowing through an agricultural field on the project
• property. Reach 4 flows in a southwesterly direction for 777 feet before dropping
• abruptly at the confluence with Nahunta Swamp. The reach exists as an incised "ES" and
"G5" Rosgen stream type. The "G5" sections of the reach are located on the upstream
and downstream portions. Stream instability is high in these sections of the reach, with
high vertical banks and active bank erosion. In the middle portion of the reach, bank
• height ratios decrease to near 1.0 and the stream is classified as an "E5." It is likely that
the low bank heights are the result of aggradation of sediments in this low slope section
of channel. This conclusion is reached because it is unlikely that channelization and
deepening of the stream would have been performed on the upper and lower portions, and
• not on the middle section.
Currently, Reach 4 has little or no pattern, due to channelization used to improve
drainage for agricultural production. The stream exhibits features typical of agricultural
• ditching, a trapezoidal shape and deep banks with steep slopes and no bedform diversity.
• The existing stream has few bed features due to the lack of pattern. The stream bed is
dominated by particles in the sand size fraction. Due to the degree of incision, down
cutting, and steep banks the stream displays signs of instability increasing the potential
. for sediment transport from the site.
Geomorphical stream parameters for Reaches 2, 3, and 4 are provided in
Appendix 1.
• 2.6.3 Tapp Tract Hydrology
In addition to the channelized streams described in the previous section, there are
several field ditches on the northern portion of the Tapp Tract that provide additional
• drainage. These ditches carry runoff and drainage from the wet hillslope area on the
• northeast side of the tract. The ditches have not been maintained well over the past few
years and are now partially clogged. As a result, portions of the field edges are saturated
during wet times of the year.
• Nahunta Wetland and Stream Mitigation Plan 2-15 EBX / Buck Engineering
Five (5) well transects were placed on the Tapp Tract with a total of 10 manually
read wells. Well data are provided in Figure 2-8. In general, the water table data indicates
that the gradient from the toe of the hill slope to Nahunta Swamp is greater than the Cole
Tract. Although the water level in Nahunta Swamp is nearly the same as the Cole Tract,
the groundwater level measured along the hill slope was found to be higher. This
information follows that of observations made in the field. Site visits during wet periods
have found the water table at the surface near the toe of the hill slope. These are areas of
hillslope seepage, where groundwater intersects or comes very close to the ground
surface. Two areas on the Tapp property have been observed to have "seeps": the
northern and central portions of the property.

2.6.4 Tapp Tract Existing Wetlands
There is an existing area of wetlands on the northeastern portion of the tract. The
wetlands appear to be primarily the result of springs and hillside seeps that discharge on
the lower portions of the hillslope. Soils in the wetland areas are classified as the Bibb
series by the county soil survey. The wetland areas show signs of past impacts. There are
remnant logging ruts in many locations, as well as small surface drainage ditches, many
of which that have now become clogged and are not longer functioning. The total area of
existing wetlands within the project property is 4.5 acres. Existing wetland areas within
the project limits will be protected with a conservation easement.

2.7 Edmundson Tract
The Edmundson Tract is approximately 65.4 acres in size with approximately 39.8
acres of prior converted fields (Figure 2-3). The tract is divided by NCSR 1534 (Big
Daddy's Road) which runs east to west across the middle of the site. The tract is situated
on the eastern floodplain of Nahunta Swamp. Existing soils are hydric within the cleared
fields, and have been drained by the use of field ditches and channelization of the stream
(Reach 5) that flows through the southern portion of the tract.
2.7.1 Edmundson Tract Existing Soils

The soil survey indicates that Johnston (Js) soils (described in Section 2.5. 1)
. occupy the level floodplain areas and cleared fields adjacent to Nahunta Swamp. Areas of
the Exum (Ex), Wagram (Wa), and Norfolk (No) series are located on the non-hydric
hillslope areas of the tract. The Exum series consists of moderately well drained, nearly
level soils on smooth, broad divides. The seasonal high water table is at a depth of about
2.5 feet. The surface layer is typically a grayish-brown and pale-brown very fine sandy
loam about 10 inches thick. The subsoil is 55 inches thick and is yellowish-brown, friable
clay loam in the upper part. The Wagram series consist of well-drained, nearly level to
strongly sloping soils on smooth, slightly convex and rounded sides of broad divides. The
seasonal high water table remains below a depth of 5 feet. The surface layer is grayish-
brown loamy sand about 8 inches thick over pale-brown loamy sand about 20 inches
thick. The subsoil is 40 inches thick and is dominantly yellowish-brown, friable sandy
clay loam. The Norfolk soil series is described in Section 2.5.1.

2.7.2 Edmundson Tract Existing Stream
Reach 5 is located on the Edmundson Tract, approximately 500 feet southeast of
NCSR 1534. This reach originates on upland areas above the project site, flowing
through a forested area before entering the project property. Reach 5 flows 1,020 feet
through agricultural fields before its confluence with Nahunta Swamp. Reach 5 exists
primarily as an incised Rosgen "E5" stream type. On the upstream end where the stream
flows onto the project property, the stream is entrenched enough to be classified as a
"G5c" stream type. The stream then flows through a farm culvert and for the remainder
of its length, it is classified as an incised "E5" or "C5" stream type. Bank height ratios are
generally less than 1.5 on the lower portions of the reach where the channel bed has
aggraded over time. As the stream approaches Nahunta Swamp, incision increases as the
stream drops to its confluence with Nahunta Swamp. The streambed is dominated by
particles in the sand fraction. Considering the location of the stream and the relative
topography of the site, it is likely that the stream was altered to increase drainage and
promote agricultural production. Reach 5 displays little sinuosity and subsequently
limited bed features. Based on field evaluations, the existing stream is unstable with areas
of active bank erosion, especially on the upper and lower portions of the reach.
Geomorphical stream parameters for Reach 5 are provided in Appendix 1.

2.7.3 Edmundson Tract Hydrology
There are several field ditches on the Edmundson Tract that collect surface runoff
and subsurface drainage and discharge to Nahunta Swamp. Some of the ditches were dug
along the hillslope areas to collect hillslope seepage and runoff. These ditches discharge
to lateral ditches and the channelized Reach 5 which route the drainage to Nahunta
Swamp.
There are three well clusters on the Edmundson Tract, with a total of 7 wells; 6
manually read wells and 1 automated well. As with the other tracts, the water table data
indicate that the local water table gradient increases closer to Nahunta Swamp (Figure 2-
9). The water surface of Nahunta swamp is approximately 4 to 5 feet below its average
adjacent floodplain elevation. However, the existing ground immediately adjacent to
Nahunta swamp is much higher due to the presence of spoil piles from past dredging.
Wet pockets of standing water and saturated soil have been observed for periods of time
during the growing season. Site visits have determined the presence of hillslope seepage
on the Edmundson Tract in certain areas. During wet periods of the year, these seepage
areas provide enough water to saturate large portions of the adjacent fields.

Figure 2-9 Water table data collected from wells on the Edmundson Tract.
2.7.4 Edmundson Tract Existinq Wetlands
There is an area of existing wetlands on the northeastern corner of the tract. The
area of wetlands located on the project property is approximately 4.0 acres in size. The
hydrology of the area appears to be fed by hillslope seepage, similar to the wetland areas
described for the Tapp Tract (Section 2.6.4). Soils within the wetland area are mapped as
Nahunta Wetland and Stream Mitigation Plan 2-18 EBX / Buck Engineering
the Johnston series. The entire wetland acreage is wooded. Existing wetland areas within
the project limits will be protected with a conservation easement.
. 2.8 Gonder Tract
The entire Gonder Tract is approximately 38.4 acres in size, with approximately
29.8 acres of prior converted land (Figure 2-4). The tract is the southernmost property on
. the east side of Nahunta Swamp. Like the Edmundson Tract, the Gonder Tract is situated
on the eastern floodplain of Nahunta Swamp. Existing soils on the cleared fields are
hydric. There is one stream on the tract which originates from upland areas offsite.

2.8.1 Gonder Tract Existing Soils
Similar to the Edmundsen Tract, soils on the cleared fields of the Gonder Tract
are mapped as the Johnston (Js) series. The Johnston series is described in Section 2.5.1.
. Soils on the upslope areas east of the cleared fields are mapped as the Lynchburg (Ly)
. and Wagram (Wa) series. The Lynchburg series is described as somewhat poorly drained,
nearly level soils on broad, smooth flats on interstream divides. The seasonal high water
table is at a depth of about 1.5 feet. The surface layer is dark gray and light brownish-
gray sandy loam about I 1 inches thick. The subsoil is about 61 inches thick. The upper
. part is pale-brown and light yellowish-brown, friable sandy clay loam mottled with light
brownish gray and brownish yellow. The middle part is gray, friable sandy clay loam
mottled with yellowish brow, strong brown, brownish yellow and yellowish red. The
. lower part consists of thin layers of dark-gray, very friable sandy loam and firm sandy
• clay loam. The Wagram series is described in Section 2.7.1.
2.8.2 Gonder Tract Existing Stream

. Reach 6 flows in a southwesterly direction for 550 feet on the Gonder Tract and
currently receives drainage from upslope, as well as shallow subsurface drainage from
the adjacent agricultural field and horse pasture. Field measurements determined that
Reach 6 is classified as a Rosgen "G5c" stream type on the upper end, and an incised
. "E5" for much of its length through the cleared field. The stream has a low width to depth
. ratio and is entrenched to moderately entrenched over much of its length. The streambed
is dominated by the sand size fraction. In its existing state, the stream has little or no
pattern or bedform features, due to channelization used to improve drainage for
agricultural production. The stream exhibits features typical of agricultural ditching
. including a trapezoidal shape and high banks with steep slopes. Like Reach 5, this reach
does not have a vegetative buffer. At the confluence of Reach 6 and Nahunta Swamp, the
elevation of Reach 6 drops abruptly. The reach lacks a vegetative buffer resulting in
increased bank erodibility as well as poor habitat for aquatic ecosystems. Due to the
. degree of incision, steep banks, and lack of a vegetative buffer, the stream displays signs
of instability increasing the potential for sediment transport from the site. Geomorphical
stream parameters for Reach 6 are provided in Appendix 1.

2.8.3 Gonder Tract Hydrology
There is a field ditch on the northeastern portion of the tract that drains in a
southern direction to Reach 6. This ditch was apparently constructed to intercept hillslope
drainage and convey it to Reach 6. The ditch is approximately 3 to 4 feet deep.
There is one well transect on the Gonder Tract with a total of 3 wells; 2 manually
read wells and 1 automated well. In general, well data indicate that the water table is the
highest in the middle of the field (Figure 2-10). Nahunta swamp forms the southwestern
boundary of the property while the northeastern boundary of the site is formed by a
shallow agricultural drainage ditch. Considering this land tract is bound by two
hydrological sinks, the water table in the center of the property would likely be higher
than the land adjacent to the hydrologic sinks. The water surface of Nahunta swamp is
approximately 4 to 5 feet below its average floodplain elevation on the adjacent ground.

2.8.4 Gonder Tract Existing Wetlands
There are no areas of existing wetlands on the Gonder Tract.
2.9 Cook Tract
The Cook Tract is the only portion of the mitigation property located on the
western floodplain of Nahunta Swamp (Figure 2-5). The Cook Tract is currently utilized
for row crop production. Site soils are hydric on the cleared fields and in much of the
wooded land on the western edge of the tract. One stream exists on the site along the
northern property line of the tract, and there are several field ditches that provide
Nahunta Wetland and Stream Mitigation Plan 2-20 EBX / Buck Engineering
drainage to the site. The total size of the Cook Tract is approximately 56.7 acres, with
approximately 31.3 acres of prior-converted cropland.
2.9.1 Cook Tract Existing Soils
The Cook Tract is mapped entirely as Johnston (Js) soils (described in
Section 2.5.1).
2.9.2 Cook Tract Existing Streams
One perennial stream exists on the Cook Tract and serves as the northwestern
property boundary between the proposed mitigation site and adjacent properties. Due to
hydrologic trespass concerns, the stream will be left in its existing condition.
Three field ditches exist within the main portion of the Cook Tract. On August 29,
2002, a representative from the Washington Regional Office of NC Division of Water
Quality performed a site inspection of the ditches and concluded that they were exempt
from compliance of EMC rules for protection and maintenance of existing riparian areas.
The reason stated for the exemption was that the ditches were man-made conveyances
created to provide drainage of the agricultural fields (copies of the field forms are
provided in Appendix 14). These drainage ditches will be filled in order to restore
wetland hydrology.
2.9.3 Cook Tract Hydrology
There are two well transects on the Cook Tract, with a total of four manual wells
and one automated well. The data collected indicate that water table depths across the
Cook Tract are not as deep throughout the year as on the other tracts of the Nahunta
properties (Figure 2-11). This is most likely due to the presence of existing wetlands
along the western edge of the tract that promote higher water table conditions as water
drains from the wetlands and through the agricultural fields on its way to Nahunta
Swamp. Saturated conditions have been observed during the growing season for brief
periods after rainfall events.
2.9.4 Cook Tract Existing Wetlands
There is an area of existing wetlands on the Cook Tract along the western side of
the tract. The area of delineated wetlands located on the tract is approximately 20 acres in
size. The hydrology of the area appears to be fed by hillslope seepage, similar to the
wetland areas described for the Tapp Tract (Section 2.6.4). Soils within the wetland area
are mapped as the Johnston series. The entire wetland acreage is wooded. Existing
wetland areas within the project limits will be protected with a conservation easement.

2.10 Hydrologic Modeling
To further investigate the current hydrologic status of the site and provide a means
for evaluating proposed restoration plans, hydrologic models were developed to simulate
site hydrology. DrainMod (version 5.1) was used to develop three hydrologic simulation
models to represent conditions at the locations of the three automated monitoring wells.
DrainMod was identified as an approved hydrologic tool for assessing wetland hydrology
by the NRCS (1997). For more information on DrainMod and its application to high
water table soils, the reader is referred to Skaggs (1980).
Model parameters were selected based on field measurements and professional
judgment of site conditions. Rainfall and air temperature information were collected from
the nearest automated weather stations, located in Goldsboro, North Carolina, as
described in Section 2.4. Measured field parameters were entered into the model and
initial model simulations were compared with observed data collected from the
monitoring wells. To calibrate the model, parameters not measured in the field were
adjusted within the limits typically encountered under similar soil and geomorphic
conditions until model simulations most closely matched observed well data. Results of
model simulations are compared with observed data in Figure 2-12. Model inputs are
presented in Appendix 2.
Trends in the observed data are represented by the model simulations. DrainMod
uses simplifying assumptions in the estimation of water table depths. When applied to a
site such as the Nahunta properties with complex hydrologic processes involving
drainage, seepage, runoff and storage, the model can be used to assess overall trends and
Nahunta Wetland and Stream Mitigation Plan 2-22 EBX / Buck Engineering
relationships but is unlikely to offer exact predictions of water table hydrology.
Although hydrograph peaks between observed and simulated data do not match exactly,
relative changes in water table hydrology as a result of precipitation events at different
times of the year correlate between observed and modeled data.

Figure 2-12 Comparison between observed and modeled water table depths.
DrainMod computes daily water balance information and outputs summaries that
describe the loss pathways for rainfall over the model simulation period. Table 2-3
summarizes the average annual amount of rainfall, infiltration, drainage, runoff, and
evapotranspiration estimated for the existing condition of the Nahunta Swamp restoration
property, based on 30 year simulations averaged over the three simulated well sites.
Infiltration represents the amount of the water that percolates into the soil and is lost via
drainage or runoff. Drainage is the loss of infiltrated water that travels through the soil
profile and is discharged to the drainage ditches or to underlying aquifers. Runoff is
water that flows overland and reaches the drainage ditches before infiltration.
Evapotranspiration is water that is lost by the direct evaporation of water from the soil or
through the transpiration of plants. From the data provided, it is clear that a significant
amount of the rainfall that falls on the site is lost via drainage and runoff to the field
ditches. Restoration of the site will involve raising the bottom elevation of the adjacent
streams and increasing the amount of surface storage available to pond water. In this way,
the respective amounts of drainage and runoff are decreased and the excess water allows
the water table to remain higher throughout the year, thus restoring wetland hydrology.

2.11 Vegetation
Land use for the Nahunta properties over the past 50 to 60 years has been row crop
. agriculture. The plant species in areas with significant riparian buffers consist of sweet
. gum (Liquidambar styraciflua), red maple (Acer rubrum), water oak (Quercus nigra),
overcup oak (Quercus lyrata), river birch (Betula nigra), tulip poplar (Liriodendron
tulipifera), hornbeam (Carpinus caroliniana), holly (Ilex opaca), and persimmon
. (Diospyros virginiana). The shrub layer is dominated by giant cane (Arundinaria
. gigantea), and southern arrowwood (Viburnum dentatum). Wax myrtle (Myrica
cerifera) and Chinese privit (Ligustrum sinense) are present between the fields and
forested areas. The herb and vine strata consists of pokeweed (Phytolacca americana),
dog-fennel (Eupatorium capillifolium), aster (Aster spp.), Royal fern (Osmunda regalis),
. blackberry (Rubus spp.), green-briar (Smilax spp.), and honeysuckle (Lonicera japonica).
. The areas on the east side of Nahunta Swamp without riparian buffers consist of species
including goldenrod (Solidago spp.), pokeweed, red maple saplings and elderberry
(Sambucus canadensis). Areas to the west without riparian buffers are dominated by
. giant cane and blackberry.

2.12 Stream Benthic Macroinvertebrates
Benthic macroinvertebrates samples were collected at four sampling sites within
the project area on April 3, 2002. Three of the sites were located on tributaries targeted
for restoration, while one site was a reference site located upstream of the project
property. Stream Reaches 1, 3, and 5 were sampled on the project properties, and Reach
1 was also sampled upstream of the project property to serve as a reference reach. The
sampling methodology followed the Qual-4 protocol listed in the North Carolina Division
of Water Quality (NCDWQ) Benthic Macroin vertebrate Monitoring Protocols for
Compensatory Stream Restoration Projects. A summary of the results of benthic
macroinvertebrate sampling for the project reach is presented in Table 2-4, with complete
results presented in Appendix 3.
Mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera),
collectively referred to as EPT taxa are considered by aquatic ecologists to be intolerant
of pollution or other forms of environmental degradation. Therefore, the presence of
Nahunta Wetland and Stream Mitigation Plan 2-24
EBX / Buck Engineering
substantial numbers of EPT taxa and individuals are considered indicative of relatively
undisturbed "higher quality" streams.

Note: *An overall healthier community is characterized by higher total and EPT taxa richness values and
lower biotic index values.
A shift in the benthic community, indicating water quality decline from upstream to
downstream, is evident in Reach 1. This is reflected by the EPT taxa richness and biotic
index metrics, which are the two major metrics used to rate water quality. The EPT taxa
richness decreased from 6 taxa at the reference reach to 0 taxa at the project reach, while
total taxa decreased from 40 to 18. Total and EPT taxa richness and EPT abundance
values were considerably higher at the reference reach than the other project reaches
indicating better water quality at the reference reach compared to the project reaches.
The low EPT Biotic Index value recorded for Reach 3 (Tapp Tract) does not accurately
reflect the low EPT Taxa Richness and EPT Abundance values and therefore should not
be considered useful for data interpretation.
Based on the macroinvertebrate sampling data provided, it is clear that stream
habitat and biological function within the project reaches have been degraded, as
compared to the reference reach data. The upstream reference site on Reach 1 provides
excellent refugia of additional species for the downstream site and other nearby project
reaches. Through the proposed restoration practices (described in Section 3), the project
stream reaches will be restored to conditions similar to those observed on the reference
site. This will include the restoration of a forested canopy and buffer, proper riffle / pool
sequences, in-stream habitat, and over-banking flooding.
2.13 Cultural Resources
In a letter dated May 14, 2003, WNRC, Inc. requested that the North Carolina
Department of Cultural Resources (NCDCR) review the project and comment on any
possible impact to cultural resources within the project area. The NCDCR determined, in
a letter dated June 12, 2003, that there were no properties of architectural, historic, or
archaeological significance which would be affected by the project (see Appendix 4 for a
copy of the letter from the NCDCR).
Nahunta Wetland and Stream Mitigation Plan 2-25 EBX / Buck Engineering
2.14 Natural Resources
The North Carolina Natural Heritage Program (NCNHP) was contacted by WNRC,
Inc. in a letter dated November 15, 2001, to determine any possible issues with respect to
significant natural resources from wetland and/or stream restoration practices on the
project site. One federally listed endangered species, red-cockaded woodpecker (Picoides
borealis), is listed for Wayne County. It is anticipated that no adverse impact will occur
from proposed restoration practices since no suitable habitat for the red-cockaded
woodpecker exists within the project property.
In a reply letter dated November 15, 2001, the NCNHP issued a "No Effect"
determination for the project site (see Appendix 4 for copies of the correspondence).
Nahunta Wetland and Stream Mitigation Plan 2-26 EBX / Buck Engineering
restored stream, as well as living root mass to increase streambank stability and create
holding areas for fish and aquatic biota.
The new stream channels will be constructed "in the dry" and all stabilization practices will
be in place prior to routing stream water into the new sections of channel. When the time
arises to route stream water into the new channel sections, plugs will be installed in the old
channel to re-direct the water into the new channel. After the water has been routed from the
former channel, the process of filling the old channel with soil will begin immediately.
Portions of the old abandoned channels will be left open and graded to form shallow
floodplain pools to increase the diversity of habitats.

3.2.1 Sediment Transport Analysis
The purpose of sediment transport analysis is to ensure that the stream restoration
design creates a stable sand bed channel that does not aggrade or degrade over time. The
overriding assumption is that the project reach should be transporting all the sediment
delivered from upstream sources, thereby being a "transport" reach and classified as a
Rosgen "C" or "E" type channel. Empirical relationships from stable sand bed channels
in North Carolina are used in this analysis.
Sediment transport is typically assessed by computing channel competency,
capacity, or both. Sediment transport competency is a measure of force (lbs/ft2) that
refers to the stream's ability to move a given grain size. Quantitative tools include shear
stress, tractive force, and critical dimensionless shear stress. Since these equations help
determine a size class that is mobile under certain flow conditions, they are most
important in gravel bed studies where the bed material ranges in size from sand to cobble,
of which only a fraction are mobile during bankfull conditions. In sand bed systems, all
particle sizes are mobile during bankfull flows; therefore, there is no need to determine
the maximum particle size that the stream can transport. However, comparing the design
shear stress values for a project reach to those computed for sand-bed reference reaches
does provide a useful comparison to determine if the stresses predicted for the design
channels are within the range of those found in stable systems.
Shear stress placed on sediment particles within a stream channel may be
estimated by the following equation:
i = yRS, where Equation (1)
T = shear stress (lb/ft2)
y = specific gravity of water (62.4 lb/ft)
R = hydraulic radius (ft)
S = average channel slope (ft/ft)
The values were calculated based on average design conditions on each of the
Nahunta design reaches, and the data are compared with sand-bed reference stream data
from the Neuse Basin in Figure 3-6. The design shear stress values plot within or slightly
lower than the scatter of data points collected from reference reaches and provide
evidence that the stresses predicted for the design channels are well within the range of
stable values calculated for the reference reaches. Therefore, excessive scour of design
channels is not expected.

Slope (ft/ft)
Figure 3-6 Comparison between bankfull shear stress and channel slope for the
Nahunta design reaches and Neuse Basin reference reach data.
For sand bed streams, sediment transport capacity is a much more important
analysis tool than competency. Sediment transport capacity refers to the stream's ability
to move a mass of sediment past a cross section per unit time in pounds/second or
tons/year. Sediment transport capacity can be assessed directly using actual monitored
data from bankfull events if a sediment transport rating curve has been developed for the
project site. Since this is extremely difficult, other empirical relationships are used to
assess sediment transport capacity. The most common capacity equation is stream power.
Stream power can be calculated a number of ways, but the most common among
geomorphologists is:
w = 7QS/W, where
w = mean stream power in W/m2
Equation (2)
7 = specific weight of water (9,810 N/m3); 7 = pg where p is the density of
the water-sediment mixture (1,000 kg/m) and g is the acceleration due to
gravity (9.81 m/s2)
Q = bankfull discharge in m3/s
S = Design channel slope (dimensionless)
W = Bankfull channel width in meters
Note: 1 ft-lb/sec/ff2 = 14.56 W/m2
Equation 2 does not provide a sediment transport rating curve; however, it does
describe the stream's ability to accomplish work, e.g. move sediment. For this analysis,
stream power values were calculated for cross over (riffle) sections along the Nahunta
design reaches and are reported in Table 3-7. These values and the design channel slope
Nahunta Wetland and Stream Mitigation Plan 3-16 EBX / Buck Engineering
were then overlaid onto Figure 3-7, which shows the relationship of stream power versus
slope for reference reach sand bed streams located within the Neuse Basin of the Coastal
Plain of North Carolina.

from the reference reaches, and follows the trend of the data and the regression line. This
provides good evidence that the design stream reaches will not aggrade or degrade.

•
As an additional check of stream design stability, the design width-to-depth ratios
(W/D) were plotted against slope and compared with data from sand bed reference
reaches in the Neuse Basin. Data collected on sand-bed systems in the Coastal Plain of
North Carolina indicate a strong correlation between W/D and slope, with W/D
decreasing as channel slope increases. The design W/D ratios are compared with
reference reach data in Figure 3-8, which shows bankfull W/D ratio versus channel slope.
The design points for the Nahunta reaches fall within the range of W/D values shown for
reference reaches under similar slope conditions.

Figure 3-8 Comparison between width-to-depth ratio (W/D) and channel slope for
the Nahunta design reaches and Neuse Basin reference reach data.
In areas where the restored channel will be connected to existing incised channels
(both on the upstream end of some reaches and where the restored channel will tie into
Nahunta Swamp), the slope of the restored channel may exceed the average design slopes
presented in Table 3-7. In areas where the average slope will be exceeded, grade control
structures will be used to protect against incision of the stream channel and to step the
channel back to the incised channel grade. Data collected from the existing stream
reaches indicates that slopes much greater than the typical slopes observed in sand-bed
channels are stable where the reaches flow into Nahunta Swamp. The reason for this
observation is that during rainfall and high flow events, the water in Nahunta Swamp
rises quickly and causes a backwater condition up the smaller tributaries. This condition
reduces the stress placed on the tributary beds near the confluence during high flow
events. Small knick-points formed by dense clay layers, woody debris, and tree roots hold
the grade of these streams at base flow conditions. Grade-control structures placed in the
restored channel will serve the same purpose, acting as knick-points and protecting
against incision.

The analyses presented in this section provide evidence that the proposed designs
for the Nahunta reaches will be stable over the long-term, and will neither aggrade nor
degrade over time.

3.3 Restoration of Wetland Hydrology

• The presence of hydric soils over much of the project site is evidence that the site
historically supported a wetland ecosystem. As is the case in much of the Coastal Plain of
• North Carolina, local drainage patterns have been altered over the last two centuries to
promote agricultural production or logging activities. Nahunta Swamp has a drainage
area of approximately 40 square miles. The hydric soils present on the floodplain areas of
• Nahunta Swamp were formed long ago before the swamp was channelized. In its
predisturbed condition, it is likely that much of the project area existed as a bottomland
hardwood or cypress-gum swamp system where hydrology was primarily supported by
flow from Nahunta Swamp. Due to the size of Nahunta Swamp, the degree of
• channelization, and the large drainage area, restoration of the project area to its
predisturbance state is not a realistic or attainable goal. As discussed in the Stream
Mitigation Guidelines drafted by the US Army Corps of Engineers and NC Division of
Water Quality (USACE and NCDWQ, 2003), "[i]t is not necessarily the goal of stream
• mitigation to return stream segments to some pre-impact condition." Instead, the
restoration plan for the site will "...establish the maximum biological, chemical, and
• physical integrity possible in the current environment" (USACE and NCDWQ, 2003).

Based on on-site evaluations of the tributaries on the project site, channelization of
the reaches was completed sometime in the past to promote drainage for row crop
agriculture as well as increase the farmable area of the site. The channelization process
eliminated the existing stream pattern by making the channel linear. In addition, channels
were dug deeper than the existing stream, disconnecting the existing stream from the
natural floodplain. Restoration of the project site will involve the restoration of these
small tributaries across the abandoned floodplains. By raising the streams back to the
floodplain elevations, an overbank flooding regime will be restored to the riverine
restoration areas of the site. Raising of the stream beds will also raise the local water
table and restore wetland hydrology. In non-riverine areas, drainage ditches and swales
will be filled such that surface drainage and runoff are reduced. In this manner, rainfall
and hillslope seepage will collect in areas away from the stream channel and restore these
poorly drained non-riverine areas.
3.4 Hydrologic Model Analyses
The DrainMod simulations that were developed to evaluate the current hydrologic
status of the restoration site (Section 2.10) were modified to estimate the hydrologic
conditions of the site under the proposed restoration practices. Model parameters that
describe the depth of stream and topographic surface storage were changed to values
representative of the described restoration practices. For example, drain depths were
reduced to represent average water levels in the restored, meandering channels. Surface
storage parameters were increased, within a range of two to four cm to represent soil
Nahunta Wetland and Stream Mitigation Plan 3-19
EBX / Buck Engineering
• scarification practices. Input files that describe cropping conditions were changed to
represent forested conditions.
. Due to the complex hydrology of the Nahunta properties, modeling of exact
. conditions on the project tracts is difficult. Many areas experience slope seepage during
wet periods of the year, soil and topographic conditions vary across the site, and the
hydrologic influence of Nahunta Swamp is difficult to predict and varies depending on
the time of the year. To estimate the hydrologic wetland conditions that the restored site
. will support, a model scenario was chosen to represent average conditions that would be
experienced across the site. The location chosen for simulation was a location
approximately 100 to 150 feet from one of the restored stream channels within the
proposed restoration area (hydric fields). This condition is believed to represent average
. conditions across the site since the targeted wetland system for the majority of the site is
. a small stream swamp system, in which the hydrology is driven largely by the stream
channel itself. Thirty (30) year simulations were run following the procedures described
in Section 2.10. DrainMod input files used to model the representative location are
. provided in Appendix 6.

This modeled scenario is presented to give an indication of the average hydrologic
conditions that would be expected across the restored site. The data indicate that the
restored hydroperiod would be approximately 7% across much of the restored wetland
site (ie. a water table within 12 inches of the soil surface for 7% of the growing season
consecutively), with some areas being wetter in depressional areas. Coastal Plain small
stream swamp systems have highly variable flows and depending on the size of the
watershed, can become dry during parts of the year. High water table conditions are often
experienced only for brief periods during the early and later parts of the growing season.
Since no wetland system is homogeneous throughout, hydrology will vary across the
restored site. Factors that will affect hydrology in any particular location include seepage
inputs and outputs, degree of ponding, frequency of stream flooding events, local soil and
subsoil conditions, runoff, and run-on.
To assess the drainage effect of the Nahunta Swamp channel on the hydrology of
the proposed wetland restoration areas, DrainMod simulations were performed. The
analyses were performed using the sub-irrigation routines provided with DrainMod,
which simulate the effect of baseflow stream conditions. Since DrainMod simulates
water table depth between two ditches, the model was setup as if there were two Nahunta
canals parallel to each other, with a permanent water level approximately six feet below
the average ground surface. Surface storage parameters were changes to 4 centimeters,
representing the surface roughing and minor depressions which will be constructed on the
site to store the maximum amount of rainfall and overbank flow. All other inputs besides
those that describe the geometry of the ditches were left the same as the model
simulations previously described in this section. The spacing between the canals was then
adjusted and model simulations run until a point between the two simulated canals met
minimal wetland hydrology (5% of the growing season). In this way, the edge of the
restored wetland area was approximated as one half the ditch spacing which met minimal
Nahunta Wetland and Stream Mitigation Plan 3-20
EBX / Buck Engineering
wetland hydrology, or approximately 150 feet for the described model parameters.
DrainMod input and output files for these simulations are provided in Appendix 6.
It should be noted that the analysis presented above is conservative and does not
take into account several hydrologic attributes which the actual restored site will
experience. DrainMod simulations cannot take into account the effect of overbank
flooding events, hillslope seepage, and perhaps most importantly, the effect of the
restored stream channels on site hydrology. The comparison between simulated
conditions and actual site conditions is presented in Figure 3.9 below. When these
additional hydrologic inputs are taken into account, it is expected that the actual drainage
effect from the Nahunta Swamp canal will be approximately 100 to 150 feet. Therefore,
the restoration areas depicted in Figures 3.1 through 3.5 have been offset from Nahunta
Swamp by 100 to 150 feet.

3.5 Vegetation Plan
The design for much of the restored project site will most closely resemble the
"Coastal Plain Small Stream Swamp" described by Schafale and Weakley (1990). Trees
to be planted include willow oak (Quercus phellos), swamp chestnut oak (Quercus
michauxii), laurel oak (Quercus laurifolia), overcup oak (Quercus lyrata), swamp
blackgum (Nyssa biflora), bald cypress (Taxodium distichum), water oak (Quercus
nigra), green ash (Fraxinus pennsylvanica), shumard oak (Quercus shumardii), and
cherrybark oak (Quercus pagoda). Overcup oak, swamp blackgum, and bald cypress will
be planted in the wettest areas.
Sections of the restored project site on the higher ground, non-riverine soil areas
will be "Non-riverine Wet Hardwood Forest" as described by Schafale and Weakley
(1990). This community will include the species listed above except for bald cypress.
The permanent seed mixture for the entire project will be composed of Virginia wild rye
(Elymus virginicus), switch grass (Panicum virgatum), and fox sedge (Carex
vulpinoidea).
3.6 Soils
Existing soils within the restoration site are hydric. Samples of topsoil from the site
will be collected and tested to determine soil fertility and chemical properties. If
necessary, soil amendments (fertilizer, lime, etc.) will be applied at rates appropriate for
the target vegetation. Since the land has been in agricultural production for a number of
years, it is likely that soil fertility amendments will not be necessary.
Disking and tillage practices commonly used in agriculture will be used to break
the plow pan and reduce compaction of the soil caused by years of agricultural
production. Tillage practices will also be used to remove any field crowns, restoring a
more natural topography to the site.

4 Success Criteria
•
Factors considered in establishing hydrologic success criteria include the site specific
water budget (Section 3.4), soil types (Section 3.6), and target wetland systems (Section
3. 1), as well as pertinent scientific literature.
•
Several examples of performance standards are discussed in the WRP Technical
Note entitled Examples of Performance Standards for Wetland Creation and Restoration
in Section 404 Permits and an Approach to Developing Performance Standards (WG-
RS-3.3), dated January 1999. Specific and measurable success criteria for plant density
. within the Neu-Con Wetland and Stream Mitigation Umbrella Bank sites are based on the
• recommendations found in the WRP Technical Note and correspondence from MBRT
members (EPA, June 15, 2001 and USFWS, December 19, 2000).

The proposed success criteria "... refer to practicably measurable or observable
• attributes that reflect compensatory mitigation objectives," which is consistent with the
cited Technical Note (page 12).

4.1 Wetland Hydrologic Success Criteria
Hydrology will be monitored through the use of monitoring wells during each
growing season for the first five years of hydrologic monitoring, or until success criteria
. have been met, whichever occurs later. To meet the hydrologic success criteria, the
monitoring data must show that for each normal year within the monitoring period, the
site has been inundated or saturated within 12 inches of the soil surface for a minimum of
12.5% of the growing season (31 consecutive days). WETS tables for Wayne County
• will be utilized to determine normal precipitation. If the restored site is inundated or
saturated within 12 inches of the soil surface for less than 12.5% of the growing season
(31 consecutive days), but the post-restoration monitoring data reflects that the site meets
applicable Corps criteria for wetlands, then the Corps and the MBRT may consider the
• site for mitigation of in-kind impacts on a case-by-case basis.
If a normal year of precipitation does not occur during the first five years of
monitoring to meet success criteria, the bank sponsor will continue to monitor hydrology
on the site until it documents that the site has been inundated or saturated as described
• above. In the alternative, and at the Corps' and MBRT's discretion, a site may be found to
meet the hydrologic success criteria on the basis of comparison of monitoring data taken
from the mitigation site, with monitoring data taken from an established reference site
that was approved by the Corps and the MBRT. The Corps and the MBRT retain the
. discretion to find that the hydrologic success criteria are met if such monitoring data from
the mitigation site and the reference site are substantially the same. This finding by the
Corps and the MBRT may be made during years with or without normal rainfall.
• In the event there are years of normal precipitation during the monitoring period,
• and the data for those years does not show that the site has been inundated or saturated as
described above during the normal precipitation year, the Corps and the MBRT may
. Nahunta Wetland and Stream Mitigation Plan 4-1 EBX / Buck Engineering
require remedial action. The bank sponsor shall perform such required remedial action
and continue to monitor hydrology on the site until it displays that the site has been
inundated or saturated as described above.
4.2 Wetland Vegetative Success Criteria
The interim measure of vegetative success will be the survival of at least 320 3-year
old planted trees per acre at the end of year three of the monitoring period. The final
vegetative success criteria will be the survival of 260 5-year old planted trees per acre at
the end of year five of the monitoring period.
Up to 20% of the site species composition may be comprised of invaders. Remedial
action may be required should these species (i.e., loblolly pine, red maple, sweet gum,
etc.) present a problem and exceed the 20% composition. Beneficial species regeneration
should be noted within the monitoring reports.
A listing of preferred canopy species to be planted on the site is provided in
Section 3.5.
4.3 Reference Site
If the rainfall data for any given year during the monitoring period is not normal,
and if the desired hydrology for the project site is not on a trajectory to achieve success,
then the reference wetland data can be assessed to determine if there is a positive
correlation between the underperformance of the restoration site and the natural
hydrology of the reference site. A description of the reference site is provided in Section
6 of this report.
The procedure described in Section 4.1 will be used to determine if normal rainfall
has not occurred in any given year.
4.4 Stream Restoration Success Criteria
Bankfull Events
Two (2) bankfull flow events must be documented within the 5-year monitoring
period. The two bankfull events must occur in separate years. Otherwise, the- stream
monitoring will continue until two bankfull events have been documented in separate
years.
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 more
unstable condition (eg. down-cutting or erosion) or are minor changes that represent an
increase in stability (eg. settling, vegetative changes, deposition along the banks, or
decrease in width/depth ratio). Cross-sections shall be classified using the Rosgen stream
Nahunta Wetland and Stream Mitigation Plan 4-2 EBX / Buck Engineering
classification method (1994) and all monitored cross-sections should fall within the
quantitative parameters defined for "E" or "C" type channels.
Longitudinal Profiles
The longitudinal profiles should show that the bedform features are remaining
stable, e.g. they are not aggrading or degrading. The pools should remain deep with flat
water surface slopes and the riffles should remain steeper and shallower than the pools.
Bedforms observed should be consistent with those observed in "E" and "C" type
channels.
Bed Material Analyses
Each project stream reach is composed of bedforms in the sand size sediment
fractions. Since the Wolman pebble count was created and tested in gravel bed streams, it
is not applicable for a sand bed channel. It is highly unlikely that a pre- and post-
restoration difference in the grain size distribution would be detectable in a sand bed
channel. Therefore, it is recommended that a post-restoration bed material analysis be
omitted from the monitoring plan.
Photo Reference Stations
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 absences 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.
Nahunta Wetland and Stream Mitigation Plan 4-3 EBX / Buck Engineering

5 Monitoring Plan
An as-built report documenting both stream and wetland restoration will be
submitted to the MBRT within 60 days of the planting completion and well installation.
The report will include elevations, photographs, well and sampling plot 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.
a The monitoring program will be implemented to document system development and
. progress toward achieving the success criteria referenced in Sections 4.1, 4.2, and 4.4.
. Wetland hydrology and vegetation as well as the restored stream morphology will be
assessed to determine the success of the mitigation. The monitoring program will be
undertaken for 5 years or until the final success criteria are achieved, whichever is longer.

Monitoring Reports will be completed on the schedule found in the approved EBX-
Neuse I Mitigation Banking Instrument (MBI) at Section V Maintenance and Monitoring
of the Bank:
Sponsor agrees to perform all necessary work to monitor the Bank and to
demonstrate compliance with the Success criteria established in this
Banking Instrument and the Site Specific Mitigation Plan(s). Members of
the MBRT may conduct, at their own expense and in coordination with
other Federal and State resource agencies, field investigations to determine
the functions and values of the Bank. The MBRT's best professional
judgment shall be used to determine wetland, upland and habitat functions
and values. Reports resulting from such investigations will be promptly
provided to Sponsor and its designated agents. The Sponsor may conduct
field investigations at its own expense to determine the functions and
values of the Bank. Reports resulting from such investigations will be
promptly provided to members of the MBRT.

Nahunta Wetland and Stream Mitigation Plan 5-2 EBX / Buck Engineering
B. Remedial Actions.
In the event the Bank or a specific phase of the Bank fails to achieve the
Success Criteria specified in the Site Specific Mitigation Plans, the
Sponsor shall develop necessary adaptive management plans and/or
implement appropriate remedial actions for the Bank for that phase in
coordination with the MBRT. The MBRT shall review the reports
described above, and may, at any time, after consultation with the
Sponsor and the MBRT, direct the Sponsor to take remedial action at the
Bank site. Remedial action required by the Corps shall be designed to
achieve the Success Criteria specified in this Site Specific Mitigation
Plan, and shall include a work schedule and monitoring criteria that will
take into account physical and climactic conditions. Sponsor shall
implement any remedial measures required pursuant to this paragraph.
5.1 Hydrology
The hydrologic success criteria are defined in section 4.1.
In order to determine if the criteria are achieved, groundwater-monitoring stations
will be installed on each mitigation tract, for a total of 13 monitoring stations across the
entire Nahunta property. Of the stations installed on each tract, at least one monitoring
station will be an automated station and the other stations will be manually read stations.
Ground water monitoring stations will follow the USACE standard methods
found in WRP Technical Notes ERDC TN-WRAP-00-02 (July 2000) as per MBRT
recommendations (stations installed prior to September 2001 were installed following
Technical Note HY-IA3.1, August 1993).
In order to determine if the rainfall is normal for the given year, rainfall amounts
will be tallied using data obtained from the Wayne County WETS Station.
5.2 Vegetation
The vegetation success criteria are defined in Section 4.2.
Successful restoration of the vegetation on a wetland mitigation site is dependent
upon hydrologic restoration, active planting of preferred canopy species, and volunteer
regeneration of the native plant community.
Nahunta Wetland and Stream Mitigation Plan 5-3 EBX / Buck Engineering

In order to determine if the criteria are achieved, vegetation-monitoring stations
will be installed on approximately 2% of the restoration site, for a total of 23 monitoring
plots. The size of individual monitoring plots will be 0.1 acre. Vegetation monitoring will
occur in spring after leaf-out has occurred. Individual plot data for woody species will be
provided. Plot data will not be averaged over the entire site to obtain a single figure for
stem density. Permanent plots for the sampling of planted species shall be randomly
located in each of the target communities. The enumeration of the density of planted
species will equal the number of remaining stems in the plot divided by the plot size in
. acres. Individual seedlings will be marked such that they can be found in succeeding
. monitoring years. Mortality will be determined from the difference between the previous

will be evaluated. For each subsequent year, until the final success criteria is achieved,
the sites will be evaluated between July and November.
•
The Corps and the MBRT retain the discretion to find that the vegetative success
criteria are met by evaluating all site data regarding vegetative success, including the data
from the vegetative monitoring plots.
•
5.3 Stream Restoration
The stream restoration success criteria are defined in Section 4.4.
Bankfull Events

The occurrence of bankfull events within the monitoring period will be
. documented by the use of a crest gage and photographs. The crest gage will record the
. highest watermark between site visits, and the gage will be checked each time there is a
site visit to determine if a bankfull event has occurred. Photographs will be used to
document the occurrence of debris lines and sediment deposition on the floodplain during
. monitoring site visits.
Cross Sections
Two (2) permanent cross-sections will be installed per 1,000 linear feet of stream
restoration work, with one (1) located at a riffle cross-section and one (1) located at a
pool cross-section. In general, cross-sections will be spaced approximately 500 feet apart.
r Each cross section will be marked on both banks with permanent pins to establish the
exact transect used. A common benchmark will be used for cross-sections and
. consistently used to facilitate easy comparison of year-to-year data. The annual cross
section survey will include points measured at all breaks in slope, including top of bank,
bankfull, inner berm, edge of water, and thalweg. Riffle cross sections will be classified
using the Rosgen stream classification system.

. The profile will be conducted for a length of restored channel at least 3,000 feet in length.
. Measurements will include thalweg, water surface, inner berm, bankfull, and top of low
. bank. Each of these measurements will be taken at the head of each feature, e.g. riffle,
run, pool, and glide, and the max pool depth. The survey will be tied to a permanent
0 benchmark.

Photo Reference Stations
Photographs will be used to visually document restoration success. Reference
stations will be photographed before construction and continued for at least 5 years
following construction. Reference photos will be taken once a year. After construction
has taken place, reference stations will be marked with wooden stakes.
Lateral reference photos: Reference photo transects will be taken at each
permanent cross section. Photographs will be taken of both banks at each cross section.
The survey tape will be centered in the photographs of the bank. The water line will be
located in the lower edge of the frame and as much of the bank as possible included in
each photo. Photographers should make an effort to consistently maintain the same area
in each photo over time.
Structure photos: Photographs will be taken at each grade control structure along
the restored stream. Photographers should make every effort to consistently maintain the
same area in each photo over time.
Benthic Macroinvertebrates
Benthic macroinvertebrate data will be collected from the reference reach
(upstream of project reach) and within the project reach. Monitoring was conducted prior
to initiation of stream restoration practices (data provided in Section 2.12). Post-
restoration sampling will begin one year after construction activities have been
completed, and annually thereafter for a total of three years. Sampling will be conducted
during summer months if significant flow is present. Sampling will be conducted
between November and March if summer flows are insignificant for project streams.
Sample collection will follow protocols described in the standard operating
procedures of the Biological Assessment Unit of the NC Division of Water Quality. The
Qual-4 collection method will be used for this project. A NC certified laboratory will
conduct the identification of the biological samples. The metrics to be calculated will
include total and EPT taxa richness, EPT abundance, and biotic index values. In the years
that data are collected, data will be provided to the MBRT with the annual monitoring
reports.

Fish Sampling
Due to the small size of the project reaches, it is recommended that fish sampling
not be included as part of the monitoring plan for the Nahunta Swamp site. Improvements
in aquatic habitat will be documented through the collection of macroinvertebrate data
from the restored stream reaches.

6 Reference Wetland and Stream Sites
6.1 Overview
Existing wetlands found within the Cole Tract will be used as the reference wetland
to document system development and progress toward achieving mitigation goals and
objectives. The site falls within the same climactic, physiographic, and ecological region
as the mitigation sites.
The reference site is located in the northeastern corner of the Cole Tract,
approximately 400 feet into the woodline at the edge of the agricultural field. The site is
an example of a "Coastal Plain small stream swamp," as described by Schafale and
Weakley (1990). These systems exist as the floodplains of small blackwater or
brownwater streams in which separate fluvial features and associated vegetation are too
small or poorly developed to distinguish. Hydrology of these systems is palustrine,
intermittently, temporarily, or seasonally flooded. Flows tend to be highly variable, with
floods of short duration, and periods of very low flow.
The reference site has experienced disturbances in the past, primarily due to timber
harvest. However, cutting of timber occurred long ago and a mature canopy of vegetation
exists across the site. It also appears that the hydrology of the site was affected little by
timber harvest.
6.2 Soils
Johnston and Bibb soils are mapped on the reference site. These same soils are
found at the mitigation site and soil profiles from both are comparable. The Johnston
series is described in Section 2.5.1 and the Bibb series is described in Section 2.6.1.
Based on soils information collected on site, soils in the area chosen for the monitoring
well (see Section 6.3 below) most closely matched the description of the Johnston series.
This location was chosen since the majority of the soils on the mitigation sites are
Johnston.
6.3 Hydrology
The site classifies as a wetland utilizing criteria identified in the USACE 1987
Manual. These criteria include the FAC Neutral Test, oxidized root channels, and local
soil survey data. Climatic conditions of the reference site are the same as those described
for the project site (Section 2.3). The reference site is classified as a "Coastal Plain small
stream swamp" (Schafale and Weakley, 1990). It is difficult to distinguish the site as
either the blackwater or brownwater subtype, as the site displays characteristics of both
communities. Small stream swamp communities are palustrine with variable flows and
are intermittently, temporarily, or seasonally flooded (Schafale and Weakly, 1990). Site
hydrology is controlled by the main stream channel that flows through the site (Reach 1),
Nahunta Wetland and Stream Mitigation Plan 6-7 EBX / Buck Engineering
as well as several seepage areas that provide additional water to the floodplain areas
during wet periods. Due to the shallow, unincised condition of the main stream through
the site and drainage from upland side slopes, high water table conditions are sustained
across the active floodplain.
A water table monitoring well was installed within the reference site on April 16,
2003. Monitoring data will be collected from the site until the completion of post-
restoration monitoring.
6.4 Stream Reference Reaches
Two reference reaches were chosen for the stream designs on the Nahunta Tracts:
1) the Cole reference reach, and 2) the Still Creek reference reach. The Cole reference
reach is a very small, meandering, sand-bed channel. The drainage area for the stream is
approximately 0.26 square miles and land use in the watershed is primarily forested with
some agriculture on the upland terraces. The site was chosen due to its stable condition
and the fact that it is located upstream of one of the project reaches (Reach 1). The
reference reach is located approximately 1,000 feet northeast of the Cole Tract, along
Reach 1 in its headwater regions. The stream flows through the bed of an old pond.
According to accounts from the landowner, the dam of the pond failed approximately 30
years ago and was never rebuilt. The Cole reference reach formed within the sediments of
the old pond, forming a single thread meandering sand bed channel with numerous
floodplain wetland areas. The reference reach site now supports a mature tree canopy
within the old pond bed.
The second reference stream site is located within the Cliffs of the Neuse State
Park, south of Goldsboro, NC, approximately 17 miles south of the project site. The
reference reach is located on the eastern side of the park along a stretch of Still Creek.
Still Creek is a small, meandering, sand-bed channel with a drainage area of 0.35 square
miles. The site was chosen due to its similar drainage area to the project reaches. The site
has a mature canopy and it appears that there has been little disturbance in recent times.
Field surveys of the reference sites were conducted in the spring of 2002. Survey
data were used to evaluate the natural channel parameters describing the dimension,
pattern, and profile of the streams. In order to properly design the streams existing on the
project site two reference reaches were used for this project. Although the streams on the
project property are very similar to each other, parameters from two reference reaches
were used to help account for the range of slopes observed on the upstream and down
stream portions of the existing streams. The Cole stream originates on the uplands before
flowing to the flat floodplain of Nahunta Swamp. The reference reach section formed
within and old pond bottom, therefore the slope of the stream is typical of sand bed
channels on alluvial valleys (0.0037 ft/ft). The reach surveyed on Still Creek had a
steeper slope and based on data collected from other sand bed systems, the stream may
represent the upper limit in slope that a stable meandering sand bed system can support
(0.0066). Both reference reaches are located within a reasonable distance of the project
Nahunta Wetland and Stream Mitigation Plan 6-8 EBX / Buck Engineering
0
• property, and both sites lie within the Neuse River Basin. Morphological stream
parameters are summarized in Appendix 7.
40 The Cole and Still Creek reference reaches are classified as "ES" channels using
• the Rosgen method (1994). The channels are classified as "B" channels since the average
• width/depth ratios are less than 12, (a width/depth ratio of 12 is the breakpoint between
classifying a channel as an "E" (< 12) or "C" (> 12)). "E" type channels typically have a
low width/depth ratio and are only slightly entrenched. "B" type streams are commonly
found in the Coastal Plain where nearly level land slopes and dense vegetation promote
• the establishment of a meandering, low width/depth ratio stream channel. The suffix "5"
indicates that the streams are sand bed systems. Both reference reach streams have
appropriate bed features for a sand-bed system, with shallow pools in the meander bends,
and deeper pools formed by scour features such as roots and debris jams. Longitudinal
• profile, cross-sections, and particle size distribution data are presented in Appendix 7 for
• both reference reaches.
r
S
Unlike many other Coastal Plain stream systems, the sections of channel surveyed
for the reference reaches show no evidence of having been altered or channelized in the
recent past. Trees can be found within the riparian area that appears to be at least 30 years
of age. Both channels have good meander pattern with low bank heights. As a result,
flooding of the adjacent riparian wetland areas occurs frequently.
6.5 Vegetation
The sub-canopy of the system is an expression of the native seed bank. Herbaceous
wetland plants and immature hardwood species are found within the area utilized as a
reference wetland. The reference site is comprised of greater than 50% facultative and
wetter species and therefore meets the hydrophytic vegetation requirement.
The reference site is well buffered along both stream banks with tree species that
include sweet gum (Liquidambar styraciflua), red maple (Acer rubrum), water oak
(Quercus nigra), overcup oak (Quercus lyrata), river birch (Betula nigra), tulip poplar
(Liriodendron tulipifera), hornbeam (Carpinus caroliniana), holly (Ilex opaca), and
persimmon (Diospyros virginiana). The shrub layer is dominated by giant cane
(Arundinaria gigantea), and southern arrowood (Viburnum dentatum). The herb and vine
strata consists of aster (Aster spp.), Royal fern (Osmunda regalis), blackberry (Rubus
spp.), green-briar (Smilax spp.), honeysuckle (Lonicera japonica), and lizard tail
(Saururus cernuus).
6.6 Benthic Macro!nvertebrates
Benthic macroinvertebrates samples were collected at three reaches within the
project property and upstream of the project area on April 3, 2002. A discussion of
benthic macroinvertebrate data for the project reaches and the Cole reference reach are
provided in Section 2.12. Benthic macroinvertebrate data was not collected on the Still
Creek reference reach. Complete results from the macroinvertebrate sampling are
provided in Appendix 5.

7 Administrative and Regulatory
7.1 HUC Service Area
The site will serve impacts in HUC 03020203 (Appendix 8).
7.2 Credit Release for Wetland Restoration
The schedule of credit availability will be dictated by the provisions of IV E.1(a) of the
Neu-Con MBI. It provides as follows:
1. Schedule of Credit Availability:
a. Advance Credits: Fifteen percent (15%) of the projected credit total for each
site (other than preservation acreage) shall be available for advance sale and
debiting, provided the following minimum requirements have been satisfied
with regard to the Bank: (i) the Banking Instrument has been approved; (ii)
the Site Specific Mitigation Plan has been approved; and (iii) a conservation
easement is placed on a Bank Site or on approved phase of a Bank Site; and
(iv) appropriate financial assurances of a type and amount acceptable to the
Corps and the MBRT have been established. Initial physical and biological
improvements necessary to achieve projected credits available for advance
sale shall be initiated no later than the first year following initial debiting from
the Bank.
For preservation acreage, the projected credit total shall be available for sale
and debiting provided the restoration requirements have been met and the
following minimum requirements have been satisfied with regard to the Bank:
(i) the Banking instrument is executed and the Site Specific Mitigation Plan
has been approved by the MBRT; (ii) credits are established consistent with
Section I.F.3 and the Site Specific Mitigation Plan; (iii) a conservation
easement is placed on the Bank Site or approved phase of a Bank Site that
generates the preservation credits; and (iv) appropriate financial assurances of
a type and amount acceptable to the Corps and the MBRT have been
established, only if such preservation acreage is used in conjunction with
restoration, creation or enhancement acreage and such financial assurance is
necessary for the restoration, creation and enhancement acreage.
b. Credit Release Schedule:
-10% after first year, if interim success measures are met (total 25%)
-10% after second year; if interim success measures are met (total 35%)
-10% after third year; if interim success measures are met (total 45%)
-15% after fourth year; if interim success measures are met (total 60%)
-15% after fifth year; if Success Criteria are met (total 75%); and
Nahunta Wetland and Stream Mitigation Plan 7-1
EBX / Buck Engineering
-25% after fifth year, if Bank Site or an approved phase of a Bank Site
meets the overall objectives and Success Criteria set forth in Site Specific
Mitigation Plan (total 100%).
If the monitoring period suggests that progress for the Success Criteria is being
met, then the credits shall be released consistent with the above schedule. The
MBRT shall review and make its determination with respect to the Success
Criteria within 60 days after receipt of the Sponsor's report. If one or more
Success Criteria is not being met, then the Sponsor will evaluate opportunities for
adaptive management or remedial bio-engineering. Adaptive management may
include, but not be limited to, installation of additional plant material,
supplementation of the vegetative community, control of undesirable invasive
exotic species, control of herbivores, modification of hydrologic regime, or
possible revision of Success Criteria based on reference site data or literature.
2. Compliance with Success Criteria:
Except as provided in Section IV.E. La, each unit of credit release as referenced in
Section III.E.l.b above shall be accepted into the Bank (available for debit) and
the appropriate transaction recorded as described in Section III.G upon delivery of
the Annual Monitoring Report. If one or more Success Criteria is not being met,
then the Sponsor will evaluate opportunities for adaptive management or remedial
bio-engineering as deemed appropriate by MBRT.
7.3 Credit Release for Stream Restoration
The schedule of credit availability will be dictated by the provisions of IV E.1(a) of the
Neu-Con MBI, which provides, in part, that the MBRT will determine the credit release
schedule.
7.4 Credit Ratios
The credit ratios for the Nahunta mitigation site, as stated in the Neu-Con MBI, are
as follows:
"The credit composition formula and procedures provided herein are
designed to ensure that there is no net loss of wetlands due to the use of
this Bank. Credits will be evaluated using the following standard:
Ratio
Restoration Acres = R (1:1)
Creation Acres = C (3:1)
Enhancement Acres = E (2:1)
Preservation Acres = P (5:1)
Stream restoration credits will be assessed as specified by MBRT."
Nahunta Wetland and Stream Mitigation Plan 7-2 EBX / Buck Engineering
The stream restoration credit ratio will be assessed at 1:1 (linear feet) consistent
with applicable guidelines.
A total of 117 acres of restoration is proposed and therefore 117 credits are
proposed to be generated for the restored wetland acreage. A total of 33.5 acres of on-site
preservation is proposed and therefore a total of 7.2 credits are proposed to be generated
from the preservation acreage. Therefore, a total of 124.2 wetland credits will be
generated from 153 acres of the Nahunta mitigation site. In addition, a total of 10,822
linear feet of stream restoration is proposed and therefore 10,822 linear feet of stream
credits will be generated. A summary of proposed mitigation credits is provided in Table
7-1.

7.5 Credit Accounting
Credit accounting will follow the procedures set forth in Section G of the Neu-Con
MBI, as follows: (See Appendix 9 for Credit Accounting Ledger)
A. Crediting/Debiting and Accounting Procedures
1. Each credit for compensatory wetland mitigation shall be comprised
of acreage consistent with the terms of Section I.F. of this Banking
Instrument. Each credit for stream mitigation shall be consistent with the
MBRT guidelines. Areas that are available for stream restoration
crediting may be considered separately from the area available for
wetlands mitigation crediting. Applicants may purchase credits from the
Bank to compensate for unavoidable wetland or stream impacts caused by
projects authorized by the Corps or by any North Carolina agency when
the permitting agency determines that compensatory mitigation is
necessary or appropriate and that the Bank is appropriate for use.
2. The Bank Sponsor will establish and maintain an accounting system
which documents the activity of the accounts and the location of the
credits used from the Bank. As part of this accounting system, Sponsor
will record the sale of credits used to compensate for impacts to wetlands
Nahunta Wetland and Stream Mitigation Plan 7-3 EBX / Buck Engineering
and the sale of credits used to compensate for impacts to streams. A
ledger will be submitted to identify the location of the actual wetland
acreage or stream footage associated with the credits. Statements will be
generated each time an approved debit/credit transaction occurs and at the
end of each season in which restoration and/or creation occurs. Sponsor
will furnish copies of all statements generated from an approved
debit/credit transaction to each member of the MBRT. Sponsor also will
compile an annual report on activity in the Bank and distribute a copy of
such report to each member of the MBRT.
7.6 Conservation Easement
Consistent with Section III G of the Neu-Con MBI, a conservation easement will
be placed over the preservation acreage in its entirety, in perpetuity, prior to the release of
any credits from the site. The easement will be recorded in the chain of title and will be
held by a qualified land trust, non-profit organization or government entity. A copy of a
sample Deed of Easement is attached (see Appendix 10). Consistent with Section III G.2,
to the extent a conservation easement is placed on acreage that is approved for credit
release and the Bank Sponsor determines that such acreage will not be debited or used;
such acreage may be released from the preservation requirement upon written notice to
and approval from the MBRT.
7.7 Financial Assurances
The financial assurances shall be consistent with the provisions set forth in III.F of
the Neu-Con MBI. It provides as follows:
F. Financial Assurance Requirements:
1. ...The sponsor will provide financial assurance in a form and amount
acceptable to the Corps and the MBRT. The financial assurance shall be
sufficient to cover the cost of the following in the event of Sponsor default
or Bank failure at sites from which credits have been debited, where
wetlands or streams are being restored, created or enhanced:
a. Actions necessary for the debited, pre-sold wetland areas, streams
and riparian corridor (exclusive of preservation acreage) in accordance
with the Banking Instrument and Site Specific Mitigation Plans.
These shall include costs of site design, topographic and boundary
surveys, manipulation of site hydrology, monitoring well installation,
grading, planting, as-built surveys, and an amount deemed appropriate
by the MBRT to cover potential remedial actions in the event Success
Criteria are not met.
Nahunta Wetland and Stream Mitigation Plan 7-4 EBX / Buck Engineering
b. Maintenance of completed wetland areas, streams and riparian
corridor (exclusive of preservation acreage) in accordance with the
Banking Instrument and Site Specific Mitigation Plans, including
sediment control, control of the undesirable plant species, maintenance
of hydrologic control structures and maintenance of monitoring wells.
C. Monitoring and reporting as required by Section V of this Banking
Instrument.
2. Upon completion of the Bank or any site or segment thereof:
a. Financial assurance required by this Section III.F. may be reduced for
the Bank or for any completed phase upon demonstration by the
Sponsor, to the satisfaction of the Corps and the MBRT, that the Bank,
site or any approved phase of a Bank Site has satisfied the Success
Criteria;
b. Financial assurance required by this Section III.F. may be further
reduced or eliminated for the Bank or for an approved phase of a Bank
Site when Sponsor demonstrates, to the satisfaction of the Corps and
the MBRT, that the Bank, segment or site is self-sustaining in its
ability to maintain compliance with the Success Criteria.
Attached hereto in Appendix I1 are financial assurances that exceed the
requirements set forth in III.F of the Neu-Con MBI.
7.8 Title
Title options for the sale of real property that constitute the Nahunta mitigation sites
are attached as Appendix 12.
