Pre-Construction Notification (PCN) Application Form
For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality Certifications, and Riparian Buffer and Watershed Buffer Rules
This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
http:/hvtiv-w.saw.usace.army.miI/wetlands/Perm app.htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://?vww.saw.usace.anny.mil/wetlands/rei2tour.htm, or contact one of the field
offices listed on page 3 of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.ne.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for General Certifications is not required, provided
that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet should
contact DWQ's Central Office in Raleigh at [phone].
Trout Waters Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on page 4 of this application).
Page 1 of 12
Coastal Area Management Act (CAMA) Coordination - If the project occurs in any of North Carolina's
twenty coastal counties (listed on page 4) the applicant should contact the North Carolina Division of
Coastal Management (DCM). DCM will determine whether or not the project is within a designated
Area of Environmental Concern, in which case DCM will act as the lead permitting agency. In such
cases, DCM will require a CAMA Permit and will coordinate the 404/401 Permits.
The applicant may also choose to coordinate with the United States Fish and Wildlife Service to ensure
that the proposed project will have no impact upon any endangered or threatened species or critical
habitat as regulated by the Endangered Species Act, and the State Historic Preservation Office, North
Carolina Department of Cultural Resources to ensure that the proposed project will have no impact upon
any properties listed or eligible for listing on the National Register of Historic Places. Compliance with
these regulations is required to be eligible for any Department of the Army permit. The addresses for
both agencies are listed on page 3 of this application.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office. Upon receipt of an application, the
USACE will determine if the application is complete as soon as possible, not to exceed 30 days. This
PCN form is designed for the convenience of the applicant to address information needs for all USACE
Nationwide, Regional or General permits, as well as information required for State authorizations,
certifications, and coordination. Fully providing the information requested on this form will result in a
complete application for any of the USACE Nationwide, Regional or General permits. To review the
minimum amount of information that must be provided for a complete PCN for each USACE
Nationwide permit, see Condition 13, 65 Fed. Reg. 12893 (March 9, 2000), available at
http://www.saw.usace.army.niil/wetlands/nwpfinalFedReg.pdf. Processing times vary by permit and
begin once the application has been determined to be complete. Please contact the appropriate
regulatory field office for specific answers to permit processing periods.
401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.ne.us/iicwet]ands/fees:litm1. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The project is involved with restoring the East Tarboro Canal to serve EEP's program
objective and mitigation needs. The project is a mitigation effort and does not impact
adjacent streams and watersheds. See Plans for specific information regarding the
restoration design.
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.
Page 9of12
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
littT)://h2o.enr.state.iic.us/ncwetiands/strmgide.htnil.
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.
The restoration plan is attached. The plan indicates the conservation easement
acquired by the state, plan views, cross section view and proposed method of
restoration.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http:/lh2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):

East Tarboro Canal Restoration Plan
Edgecombe CountY, NC
1.0 INTRODUCTION
The North Carolina Ecosystem Enhancement Program (NCEEP) has identified two
portions of the East Tarboro Canal as potential stream restoration sites. The East Tarboro
Canal is located in the town of Tarboro in Edgecombe County, North Carolina (Figure 1).
The most upstream segment (Reach 1) begins at the outlet of the culvert under Forest
Acres Drive and proceeds downstream to the town property line crossing the creek
adjacent to the end of the Rosewood Drive cul-de-sac (--1,900 linear feet). The work in
this section will consist of stream enhancement. The downstream segment (Reach 2)
begins at the outlet of the culvert under Martin Luther King Jr. Drive and proceeds
downstream for approximately 2,900 linear feet to the inlet of the St. James Street cross
pipes. Stream restoration is proposed for this Reach. Patillo Elementary School is
immediately to the west of: the Canal on Reach 2.
The town actively maintains East Tarboro Canal by dredging and cleaning debris out of
both reaches. According to the town, this maintenance work is being done for flood
control purposes. Appendix A contains a photo log of the site depicting existing
conditions of the canal.
Vegetation throughout the majority of the site is minimal due to channel degradation and
maintenance. Along Reach 1, there are row plantings of alternating loblolly pines (Pious
taetln) and crapemyrtles (Lagerstroemia indica) situated on the roadway shoulders that
flank both sides of the canal. A majority of Reach 2 runs through a grassed park area. In
Reach 2, there are no trees nor shrubs until the most downstream 300 feet where the town
does not maintain the channel on both sides. There is a woody buffer along the left bank.
The combination of extreme streambank erosion, lack of vegetation, and the cooperation
of property owners make this an excellent potential restoration site.
Restoration and/or enhancement requires determining how far the stream has departed
from its natural stability and then establishing the stable form of the stream under the
current and future hydrologic conditions within the drainage area. The proposed
enhancement on Reach 1 will involve raising the streambed in a few locations, vegetation
planting, and the placement of structures to create a riffle-pool sequence that is currently
lacking. The proposed restoration on Reach 2 will involve construction of stable meander
geometry, modification of the channel cross-sections, and establishment of a floodplain at
the existing stream elevation, thus, restoring a stable dimension, pattern, and profile. This
restoration is based on analysis of current watershed hydrologic conditions, field
evaluation of the project site, and the assessment of a stable reference reach. The
following recommendations are included in this restoration plan:
• Form a stable channel with the proper dimension, pattern, and profile;
• Establish a floodplain along the stream channel where possible;
• Place natural material structures in the stream to improve stability and enhance
aquatic habitat;
• Stabilize streambanks with herbaceous and woody vegetation; and
• Restore/enhance the streams riparian zone.

East Tarboro Canal Restoration Plan
Edgecombe County, NC
1.1 PROJECT DESCRIPTION
For purposes of this report, the restoration site is broken into two segments or reaches:
Reach 1 lies between Forest Acres Drive and Rosewood Drive (1,917 linear feet) and
Reach 2 extends 2,887 linear feet between Martin Luther King Jr. Drive and St. James
Street. In reach 1, the East Tarboro Canal flows to the south and then to the southeast at
the reach 1 terminus of construction. In Reach 2, the East Tarboro Canal flows
southwesterly to the Tar River. Through both reaches the Town of Tarboro and
Edgecombe Board of Education are the primary landowners. Several storm drainage
pipes flow into the East Tarboro Canal along Reach 1. Two small drainage ditches, one
Swale, and several drainage pipes enter the canal downstream of Martin Luther King Jr.
Drive in Reach 2.
1.2 GOALS AND OBJECTIVES
There are five overall goals for the project in its entirety. Each reach also has specific
objectives to address particular problems within in each. The following are the overall
goals:
1. Provide a stable stream channel that neither aggrades nor degrades while maintaining
its dimension, pattern, and profile with the capacity to transport its watershed's water
and sediment load.

2. Reconnect the canal to its floodplain and/or establish a new floodplain at a lower
elevation.
3. Improve aquatic habitat with the use of natural material stabilization structures such
as root wads, cross-vanes, woody debris, and riparian buffers.
4. Provide aesthetic value, wildlife habitat, and bank stability through the creation of a
riparian zone.
5. Stabilize and enhance the small drainages that enter the site.

In addition to the above goals, Reach I has the following specific objectives that will be
met for an Enhancement Level 1:
• Reducing erosion;
0 Providing in-stream habitat;
0 Protecting sewer and water lines from channel down-cutting;
0 Planting native urban landscaping species; and
• Installing structures for adding in a riffle-pool system.

The following goals and objectives must be met to obtain full restoration credits for
Reach 2:

• Reducing flooding problems;
• Plantin- native urban landscaping species; and
0 Enhancing habitat through a wildlife corridor.
1.3 STREAM SURVEY METHODOLOGY
The US Forest Service General Technical Report RM-245, Stream Channel Reference
Sites: An Illustrated Guide to Field Technique is used as a guide when taking field
measurements (Harrelson et al 1994). Accurate field measurements are critical to
determine the present condition of the existing channel, conditions of the floodplain, and
watershed drainage patterns.
Earth Tech contracted with 4D Site Solutions, Inc. to conduct a topographic survey of the
restoration site in September 2004. This mapping is used to evaluate present conditions,
new channel alignment, and grading volumes. Mapping also provides locations of
property lines, large trees, vegetation lines, culverts, roads, and elevations.
A stream survey of the property was conducted to better evaluate the drainage properties
of the area surrounding the restoration site on August 21-22, 2004. A windshield survey
was also conducted to determine the existing conditions within the watershed. During the
site visit, three cross-sections on Reach 1 and eight cross-sections on Reach 2 were taken
using standard differential leveling techniques. These cross-sections were used to gather
details on the present dimension and condition of the channel. Due to recent channel
disturbances, a bankfull feature was not reliably identified in the field. Cross-sectional
area was calculated using the best estimate of the bankfull feature identified in the field.
See Appendix B for a copy of the existing condition survey for the East Tarboro Canal.
1.3.1 Stream Delineation Criteria - Classification
Dave Rosgen developed his stream classification system in order to accomplish the
following:
1) Predict a river's behavior;
2) Develop specific hydraulic and sediment relationships for a given stream type and its
state;
3) Provide a mechanism to extrapolate site-specific data to stream reaches having
similar characteristics; and
4) Provide a consistent frame of reference for communicating stream morphology and
condition among a variety of disciplines and interested parties.
The Rosgen Stream Classification System is based on five criteria: width/depth ratio,
entrenchment ratio, slope, sinuosity, and channel materials (1996). The cross-sections
were classified using this system based on the few bankfull features present in the
existing channel.

1.3.2 Bankfull Verification
The foundation of Dave Rosgen's classification system is the concept of bankfull stage,
which is the point of incipient flooding. The classification depends on the correct
assessment of bankfull. It is important to verify the physical indicators observed in the
field with either gage data or a regional curve to ensure the correct assessment of the
bankfull stage.
The bankfull stage is determined in the field using physical indicators. The following is a
list of commonly used indicators that define bankfull (Rosgen, 1996):
• The presence of a floodplain at the elevation of incipient flooding;
• The elevation associated with the top of the highest depositional feature (e.g. point
bars, central bars within the active channel). These depositional features are
especially good stage indicators for channels in the presence of terrace or adjacent
colluvial slopes;
Y A break in slope of the bank and/or a change in the particle size distribution, since
finer material is associated with deposition by overflow, rather than deposition of
coarser material within the active channel;
• Evidence of an inundation feature such as small benches below bankfull; and
• Staining of rocks.
Bankfull indicators were weak throughout both reaches of East Tarboro Canal. In Reach
1, there was a break in slope where a small bench has formed. In Reach 2, the channel
had developed sinuosity and perhaps an inner berm where the town had not recently
excavated the channel. Where the channel was recently excavated, there were no
bankfull indicators due to the trapezoidal characteristics of the canal. In the lower section
of Reach 2. where there were less human disturbances, a relatively consistent bankfull
indicator was located along the left bank.
In ungauged areas like the East Tarboro Canal, Dave Rosgen recommends verifying
bankfull with the development of regional curves. The regional curves normally plot
bankfull discharge (Qbkt), cross-sectional area, width, and depth as a function of drainage
area. The cross-sectional areas of both reaches of the East Tarboro Canal, the reference
reach, and the proposed design area are plotted on the North Carolina Coastal Plain
Regional Curve developed by the North Carolina State University (NCSU) Water Quality
Group, 2003 (Figure 2).
Data obtained from field surveys described in Section 2.2.2 were used to compute the
morphological characteristics shown on the graph. The cross-sectional area for both
reaches of East Tarboro Canal plot just above the trend line on the NC Coastal Plain
Regional Curve (Figure 2).

2.1 WATERSHED
1?9 2.1.1 General Description of the Watershed
East Tarboro Canal, a perennial stream, is located within the Coastal Plain Physiographic
Province of the Tar River Basin (USGS Cataloging Unit 03020103). The watershed is
located to the northeastern section of the Town of Tarboro in Edgecombe County, North
Carolina. From the headwaters, the East Tarboro Canal flows for approximately 2.5
miles before entering the Tar River. Several small drainages enter the East Tarboro Canal
along its extent.
'T'ile watershed for East Tarboro Canal is approximately 2.19 square miles (1,402 acres) at
the end of Reach 2 (Figure 3). The watershed is oriented north to northeast. The
topography of the watershed is relatively flat with wide floodplains. Land surface
elevations range from approximately 16 to 72 feet above mean sea level. There are
approximately 690 acres in the headwaters of this watershed that are currently
undeveloped. Due to the relative proximity to the Town of Tarboro, it is likely that these
parcels of land may be developed in the future.
2.1.2 Surface Waters Classification
Surface waters in North Carolina are assigned a classification by the Division of Water
Quality that is designed to maintain, protect, and enhance water quality within the state.
The East Tarboro Canal is classified as Class C; NSW (28-(80)). Class C waters are
freshwaters protected for secondary recreation, fishing, and aquatic life including
propagation and survival, and wildlife.) The NSW classification is for waters that need
additional nutrient management strategies for both point and non-point source pollution.
2.1.3 Land Use of the Watershed
r
Land use within the watershed consists of commercial, residential, forested, and disturbed
areas (sand quarry). Approximately 49% of the watershed is classified as
agricultural/forested, 25% residential, 16% is a combination of commercial, industrial
and institutional, and the remaining 1190 is maintained (i.e. roads). Evaluation of a
USGS topographic map reveals that approximately 18% of the watershed is impervious.
Based on conversations with town officials, the East Tarboro Canal has been actively
maintained for at least 30 years. The channel maintenance was conducted to relieve
flooding issues in the area.

2.2 RESTORATION SITE
East Tarboro Canal Restoration Plan
Edgecanbe County, NC
The following sections provide a description of existing site conditions. This includes the
current stream conditions, soils, and surrounding plant communities.
2.2.1 Site Description
The project site begins downstream of Forest Acres Drive and flows for approximately
1,900 ft. in Reach 1. Reach 2 begins downstream of Martin Luther King Jr. Drive and
continues downstream for approximately 2,900 linear ft. to Saint James Street. The
project is located primarily on Town of Tarboro and the Edgecombe County Board of
Education properties. Channel sinuosity for the entire reach is 1.02, with long straight
stretches. High banks and areas of severe bank erosion can be found throughout both
project reaches due to high in-stream shear stress and lack of streambank vegetation.
The causes of impairment throughout the restoration site are:
• Upstream development
• Road embankments adjacent to the streambanks on Reach 1;
• Previous channelization;
• Removal of riparian vegetation;
• Sedimentation on both reaches;
• Maintenance by the Town of Tarboro Public Works Department for flood
control, and
• Recent channel modifications due to utility work and flood control.
2.2.2 Existing Stream Characteristics
Field surveys of the existing stream channels and surrounding floodplains were
conducted to determine the potential for stream restoration on-site. The stream
measurements are critical to the classification and assessment of the existing stream type.
These measurements provide data to classify the stream using the Rosgen classification
method, Levels I and 11 (Rosgen 1996).
Photographs of the site were taken and are provided in Appendix A. The channel can be
typically described as a canal maintained by the Town of Tarboro for flood control
(Figure 4). Although the channel is deeply incised and both reaches classify as 135c,
Reach 2 is currently attempting to meander at a lower elevation by establishing a stable
dimension, pattern, and profile within the new floodplain. Streambank erosion
throughout the site is a result from pattern modifications and the lack of stream bank
vegetation. An erosion assessment using the Bank Erosion Hazard Index was performed
at each cross-section. Overall the banks of the canal in Reach 1 have high erosion
potential while Reach 2 erosion potential varies from low to very high. Heavy rains,
sandy soils, and a lack of vegetation have left unprotected soil on the streambanks
I vulnerable to erosion.

2.2.3 Soils of the Restoration Site
According to the Edgecombe County Soil Survey (USDA-SCS, 1979) several soil types
are present in the project area (Figure 5). The soils mapped along the floodplain of the
East Tarboro Canal in Reach I are Roanoke loam and Gran thani- Urban land complex.
The soils mapped along the floodplain of the East Tarboro Canal in Reach 2 are
Portsmouth fine sandy loam and Roanoke loam. Surface runoff from these soils is slow
to very slow and sometimes ponded in Portsmouth soil. Grantham, Portsmouth, and
Roanoke soils are considered to be hydric by the NRCS. Soil units mapped by the NRCS
along the floodplain at the site are briefly described below.
Grantham-Urban land complex (Gt). This unit is a poorly drained soil formed in
Coastal Plain sediments and is found on nearly level broad interstream divides and
shallow depressions in the uplands. The seasonal high water table is at the surface to 1
foot below the surface from December through March.
Portsmouth fine sandy loam (Pu). This unit is a very poorly drained soil formed in
fluvial sediments and is found on nearly level broad flats and depressions on stream
terraces. The seasonal high water table is at the surface to I foot below the surface
throughout the year. A few small areas are subject to flooding.
Roanoke loam (Ro). This unit is a poorly drained soil formed in fluvial sediments and is
found on nearly level broad flats and depressional areas along stream terraces. The
seasonal high water table is at the surface to I foot below the surface from November
through May. This soil is typically frequently flooded for brief periods.
The uplands immediately adjacent to the channel in Reach 2 are mapped as State loamy
sand and Norfolk-Urban land complex. Land use and management of these soils may
impact the soils in the project area.

2.2.4 Geotechnical Investigations
Froehling & Robertson, Inc. has performed Geotechnical investigations for both stream
reaches. The report is located in Appendix D. A total of five soil test borings were
performed. Soils encountered are predominately loose sands, soft clays, and stiff silts.
Due to the loose and soft condition of the native sand, Froehling & Robertson, Inc
recommend that stream banks be graded no steeper than 3 Horizontal to 1 Vertical
(3H:1 V) for slope stability. In some locations, slopes of 2.5H:1 V maybe used.
2.2.5 Terrestrial Plant Communities
The following sections describe the existing plant communities on and adjacent to the
restoration site (Figure 4). Historically the entire floodplain of the East Tarboro Canal
was most likely a continuous bottomland hardwood ecosystem connecting, flooding, and
draining numerous adjacent wetlands. This ecosystem is now altered and fragmented by
various land uses. The previous floodplain is no longer available for overbank flows
because of filling of the floodplain and channel incision. The communities that now exist
along the East Tarboro Canal are drier, well drained urban landscapes that no longer
resemble the original plant communities. Nomenclature follows Radford et al (1968) and
the National Plants Database (USDA-NRCS 2004).
2.2.5.1 Street Scape
The upper reach of this project is located between two urban residential streets, East
Canal Street and West Canal Street. Within this reach the banks are steep to nearly
vertical and lack woody vegetation. Herbaceous vegetation is reduced because of the
frequent mowing. The area between the top of the banks and the edge of pavement is
frequently maintained. Vegetation consists of a row on each bank consisting of loblolly
pines (Pines taeda) that alternate with crapemyrtle (Lagerstroemia indica) and photinia
(Photinia sp.). The closely mowed grass is centipede grass (Eremochloa ophiuroides).
Although overbank flooding occurs on occasions, this area is relatively dry because of the
deeply incised channel and well-drained, sandy soil surrounding the channel.
2.2.5.2 Maintained Grass Field
An area consisting of an open grass field, parking lot, and picnic area is located in the
middle and lower reaches near Patillo Elementary School. The area surrounding the
stream is herbaceous and is maintained regularly through mowing, often to the edge of
the channel. Species within the open field include Bermudagrass (Cynodon dactylon.),
centipede grass, crab grass (Digitaria sp.), bahiagrass (Paspalum notatian), Carolina
horsenettle (Solantan carolinense), and buckhorn plantain (Plantago lanceolata).
Vegetation in the channel included a few other species including soft rush (Juncus
effuses) and sedges.

2.2.5.3 Wooded Buffer
A narrow wooded buffer is located in the lower reach along the east side of the canal.
Beyond this buffer is a field with agricultural row crops. The woody species found
within the buffer include sweet gum (Liguidambar styriciflua), water oak (Quercus
nigra), river birch (Belula nigra), common elderberry (Santbucus nigra ssp. Canadensis),
Japanese honeysuckle (Lonicera japonica), and privet (Ligustrunt sinense). The canal is
wider and less maintained in this section. Much of the vegetation canopies the a portion
of the channel. Within this reach, additional herbaceous species are found including
deertongue (Dichanthelium clandestin?un), Virginia dayflower (Commelina virgnrtca),
and eastern gamagrass (Tripsacum dactyloides). Within the channel, wartremoving herb
(also called Asian dayflower) (Mur(lannia keisak) is also present.
2.2.6 Wildlife Observations and Protected Species
Wildlife and signs of wildlife were noted during on-site visits; however, a formal wildlife
survey was not performed. Tracks of white tailed deer (Odocoileus virginianus) and
raccoon (Procyon lotor) were observed along the stream banks.
The USFWS lists two species under federal protection and seven species of federal
concern for Edgecombe County (list updated February 13 2003 - USFWS 2004). These
species are listed in Table 2.

1 3.0 REFERENCE REACHES
3.1 Unnamed Tributary to Mill Creek

Gast Tarboro Canal Restoration Plan
Edgccombe County, NC
The Unnamed Tributary to Mill Creek (UT Mill Creek) is a first order stream flowing
into the Ncuse River in Bentonville located in Johnston County, NC (Figure 6). The
watershed area is approximately 608 acres (0.95 square miles), most of which is rural
farmland.
The watershed boundary to the east is NC 1197 (Bentonville Road), to the south SR 1009
(Devils Racetrack Road), and then follows the ridgelines to the reference reach site. The
watershed is predominately comprised of single-family residences, forested areas, and
farms.
Approximately 280 linear feet of this stream was surveyed on September 13, 2004 to
obtain the morphological data. This length of channel was determined from tile bankfull
width of the first cross-section that was taken (10.8 ft. wide). The reference reach length
falls within that recommended by Rosgen; a range of 20 to 30 bankfull widths.
The streambed is composed of sand with some small gravel in the riffle cross-sections.
Signs of recent overbank storm flows are evident by the amount of debris on the
upstream side of trees in the floodplain. This reference classifies as a C5 stream type
with a mean width-to-depth ratio of 13.4 and a sinuosity of 1.28. The complete data set
for this reference reach can be found in Appendix C and a summary can be found in
Table 2.
The vegetation is of fairly good reference quality, given the difficulty of finding
undisturbed stands of forest. The canopy trees are a mixture of age classes, but very few
are of large diameter. Pines are a minor component, indicating that the stand is
approaching maturity. The canopy is relatively dense, reaching approximately 60 feet in
height with the mid-canopy still developing. A few trees appeared to be older and may
have been established along the buffer prior to the existing forest development. Canopy
and subcanopy trees include sweetgum, red maple (Acer rubrian), yellow poplar
(Liriodendron tulipifera), swamp chestnut oak (Quercus michauxii), loblolly pine, and
swamp tupelo (Nyssa biflora). Shrubs and vines are abundant but not dense and include
coastal doghobble (Leucothoe axillaris), sweet pepper bush (Cletltra ahtifolia), swamp
greenbriar (Smilax laurifolia), grape (Vitis sp.), American holly (Ilex opaca), and
greenbriar (Smilax rotundifolia). The herbaceous layer includes Nepalese browntop
(Microstegittm vintineunt), cinnamon fern (Osnumda cinnamomea), and giant cane
(Arundinaria gigantea). Wetter areas on the floodplain and along the stream also
included netted chain fern (IVoochvarclia areolata) and jewel weed (Impatiens capensis).
This community appears to be a marginal example of a Quercus ntichauxii - Quercus
pagoda Saturated Forest Alliance (1.13.2.N.g.7).

REFERENCE REACH
UNNAMED TRIBUTARY
TO MILL CREEK

East Tarboro Canal Restoration Plan
Edgecombe County, NC
4.0 STREAM CHANNEL DESIGN
The proposed design is based upon Dave Rosgen's natural channel design methodology.
As described in Section 3.0, UT to Mill Creek was utilized as a reference reach on which
the morphological characteristics were measured to determine a range of values for the
stable dimension, pattern, and profile of the proposed channel. The existing, reference,
and proposed morphological characteristics are shown in Table 1.
Reach l will be modified to improve the bedform and to increase the vegetation on the
streambanks. The two roads that bound the project, East and West Canal Street, restrict
any pattern adjustment. However, bankfull benches and grading of the slope will be
performed in order to improve the stream's dimensional characteristics. This design will
be classified as Enhancement due to the fact that only the profile and dimension will be
modified in addition to the vegetation.
The design of Reach 2 will include dimension, pattern and profile adjustments in addition
to vegetation and buffer establishment. Therefore, this reach will qualify for Restoration
credits. The proposed stream will include a meandering plan form that incorporates in-
stream natural material structures for stability and habitat value. The drainages that enter
the canal in this reach will be incorporated into the design, which will integrate a stable
tie-in with the East Tarboro Canal. There will be no natural channel design of these
minor drainage ways, other than in-stream structures at the tie-in with the main channel.
A conceptual design was developed from the range of values listed in Table 1. This
project will enhance approximately 1,833 linear feet in Reach I and restore
approximately 2,916 linear feet of Reach 2 as measured along the proposed centerline of
East Tarboro Canal (excluding culvert lengths). The plan view of the proposed
restoration design can be seen in Figure 7.
4.1 RESTORATION TECHNIQUES
Stream dimension, pattern, and profile will be adjusted so the new stream channel can
maintain stability while transporting its water and sediment load. Enhancement will
involve adjusting the profile and dimension of Reach 1 while the dimension, pattern and
profile of Reach 2 will be modified to qualify as restoration of the East Tarboro Canal
(Figure 7).
Vegetation will be used to provide stability and provide habitat along the streambanks
and in the riparian area. In Reach 1, primarily low growing shrubs and herbaceous
vegetation will be planted due to the limited width of the buffer, adjacent landowner
concerns, and sight constraints for traffic. Reach 2 will include the addition of more
woody vegetation in the form of trees and shrubs in addition to herbaceous vegetation.
Reach 2 has a wide floodplain available for buffer establishment. The main landowner in
this reach is the Town of Tarboro, which is a great advantage to this project.

East Tarboro Canal Restoration Plan
Edgecombe County, NC
4.1.2 Pattern Geometry
The existing pattern of the East Tarboro Canal can be described as long straight reaches
followed by sparse meanders. The current sinuosity in Reach l is 1.01 and 1.03 in Reach
2. Design sinuosity for the East Tarboro Canal is 1.20 to 1.35 in Reach 2. The pattern in
Reach 1 will remain unchanged due to lateral constraints. The proposed pattern in Reach
2 is limited in a few places due to utility crossings, property lines, and road crossings.
A stable pattern will be achieved by introducing meanders into the stream with
appropriate radius of curvatures and lengths based on reference reach data from the
Tributary to Westbrook Mill Creek and existing constraints. Introduction of these
meanders will improve habitat while lowering shear stress.
Multiple pipe and ditch systems enter the main stream along both reaches. These will be
tied to the main channel using a combination of ditch realignment, augmentation of
piping systems, and dissipater basins. Floodplain pools will be used to collect storm
water and treat it to enhance water quality. Tie-ins will typically be done downstream of
pool forming structures to minimize the risk of erosion at stream confluences.
4.1.3 Bedform
The existing bedform along the East Tarboro Canal is fairly uniform. Long, straight
sections of the channel consist of predominantly run bedform features. The design
channel will incorporate riffles and pools to provide bedform common to C-stream types
with sand substrate. Pools will be located in the outside of meander bends with riffles in
the inflection points between meanders. Riffles in Reach l will have a mean depth of
1.00 ft. and a thalweg depth of 1.60 ft. while the pools will be deeper with a maximum
depth of 2.00 ft. Reach 2 will have a mean riffle depth of 1.46 ft, a maximum depth of
2.50, and a pool depth of 3.33 ft. The proposed longitudinal profile is shown in Figure 9
for Reach 2.
The existing pool-to-pool spacing on the East Tarboro Canal, Reach 2 is 44 to 133. The
proposed spacing is 32 to 86 ft., which is within the range of 1.5 and 4.1 bankfull widths
as determined from the reference reach data. To accomplish this, pools will be realigned
or constructed such that they will be located in the outside of the meander bends.
Bedform will also be addressed through the strategic placement of natural material
structures such as cross vanes, grade control vanes, root wads, and stone sills.
Modifications to the bedform will provide stability and habitat to the channel.
4.1.4 Riparian Areas
A riparian zone will be created around the new proposed stream channel to enhance both
aquatic and terrestrial habitat as well as stabilize the stream channel. The riparian zone
® will extend from the top of bank to the conservation easement boundaries (Figure 7& 8).
® These areas will be planted with appropriate riparian vegetation as described in Section
5.0 Habitat Restoration.

East Tarboro Canal Restoration Plan
Edgecombe County, NC
4.2 SEDIMENT TRANSPORT
A stable stream has the capacity to move its sediment load without aggrading or
degrading. The total load of sediment can be divided into bedload and wash load. Wash
load ?s normally composed of fine sands, silts and clay and transported ?n suspension at a
rate that is determined by availability and not by stream hydraulics. Bedload is
transported by rolling, sliding, or hopping (saltating) along the bed. At higher discharges,
some portion of the bedload can be suspended, especially if there ?s a sand component in
the bedload. Bed material transport rates are essentially controlled by the size and nature
of the bed material and hydraulic conditions (]ley 1997).
Critical dimensionless shear stress can be calculated for gravel and cobble bed streams
using sediment entrainment calculations. However, the bed material of both Reach 1 and
2 of the East Tarboro Canal classifies as sand. All particles in a sand bed channel have
the potential to become mobilized during bankfull events.
Shear stress at the riffle was also checked using Shield's Curve. The shear stress placed
on the sediment particles is the force that entrains and moves the particles, given by:
r = yRs
where, T=shear stress (lb/ft2)
=specific gravity of water (62.4 lb/ft)
R=hydraulic radius (ft)
s=average bankfull slope (ft/ft)
Hydraulic radius is calculated by:
R= P
where, R=hydraulic radius
A=cross-sectional area (ft)
P=wetted perimeter (ft)
Thus,
12.0 ft 2
Re achl : R = 12.6 ft = 0.95 ft
29.25 ft z
Re ach2 : R = = l .40 ft
20.96 ft
Wetted perimeter and cross-sectional area were measured off of a CADD file of the
typical riffle cross-section drawn to scale.
C
35
East Tarboro Canal Restoration Plat
Edgecombe County, NC

Therefore,
Re achI : r = (62.4 113 )(0.95 Jc)(0.0022 '/l) 0.1311) / Jt'
Jt .fl
Re ach2 t = (62. )(1.40 f't)(0.00I S '?t > 0.161121 Jt'
13 The critical shear stress for the proposed channel has to be sufficient to move the Dsa of
the riffle bed material, which is sand for both reaches of East Tarboro Canal. Based on a
shear stress of 0.13 or 0.16 lb/ft2, Shield's Curve predicts that this stream can move a
particle that is, on average, greater than 10 nun (medium gravel). Since the D84 was less
than 2 mm and Shield's Curve predicts, on average, 10 mm, the proposed stream has the
competency to move its bedload. Rosgen has also generated a curve that piggybacks
Shields Curve (Appendix B). Rosgen recommends using this curve when the critical
shear stress falls below 1.0 lb/ft2 and Shield's Curve above 1.0 lb/ft2. This curve predicts
that a 35 mm particle will be moved based on the critical shear stress of 0.13 to 0.16
lb/ft2. The largest particle measured during the pebble count was less than 2 mm. These
particles would be moved as predicted by either curve.
4.3 FLOODING ANALYSIS
The East Tarboro Canal is a Federal Emergency Management Agency (FEMA) regulated
stream with a detailed study. The proposed stream restoration project is located within a
zone AE flood hazard area (Figure 10). Zone AE indicates areas inundated by the 100-
year recurrence storm event. Along the downstream reach, work shall be performed both
in the floodplain and in the floodway. A new floodplain will be excavated so that the
active stream will be able to access it during larger storm events. Additionally, the stream
profile will be altered somewhat and the stream channel form will change radically. This
will likely necessitate adjustments to the FEMA FIRM (Flood Insurance Rate Map).
Therefore, requests for both Conditional Letter of Map Revision (CLOMR) and follow-
up Letter of Map Revision (LOMR) will be required. Since the floodplain is to be
lowered, consequently decreasing cross sectional area, it is believed that the stream
restoration will lower flood elevations in this reach. During Hurricane Floyd, most of the
structures located in the floodplain in this area received substantial damage and were
demolished. The majority of these properties were "bought-out" by FEMA and, as a
result, the property in the 100-year floodplain is generally structure-free and Town-
owned.
Work to be performed on the upper reach involves mainly the placement of structures,
planting, minimal channel bed re-profiling, minimal grading and re-shaping of the
dimensional characteristics. All work shall be done in the existing floodway. During the
design process, it will be endeavored to maintain flood elevations at or below existing
flood elevations. Unless a FEMA FIRM adjustment is to be done, FEMA regulations
require (section 60.3 (b) 7) that communities assure that the flood carrying capacity
within the altered or relocated portion of watercourses be maintained. Consultation with

Reach
/

the local floodplain administrator and hydraulic analysis shall be performed during final
design to determine the relevance of CLOMR/LOMR submittals for this reach.
In order to meet FENIA requirements and assess the flooding effects of the proposed
project, a hydraulic analysis will be performed using FEMA accepted modeling software
(HEC-RAS, HEC-2) for both the existing conditions and the proposed conditions. This
analysis will aid in taking the necessary action to protect structures, if any, impacted by
changes to the hydraulic environment and will verify assumptions made during the design
process.
4.4 STRUCTURES
Several different structures made of natural materials will be installed along the East
Tarboro Canal. These structures include cross vanes, root wads, and sills. Vegetated
gcogrids and brush layering may also be used on a limited basis. Figures 1 1 contain the
details for the proposed structures. Natural materials such as boulders, logs, root wads,
and vegetation cuttings will be used to create these structures from both off-site and on-
site sources.
4.4.1 Cross Vane
A cross vane structure serves to maintain the grade of the stream. The design shape is
roughly that of the letter "U" with the apex located on the upstream side. Footer rocks
are placed in the channel bottom for stability. Rocks are then placed on these footer rocks
in the middle of the channel at approximately the same elevation as the thalweg. On
either side of the channel, rocks are placed at an angle to the streambank, gradually
inclining in elevation until they are located above the bankfull surface directly adjacent to
the streambank. Water flowing downstream is directed over the vane towards the middle
of the channel. Rocks placed at the apex determine the bed elevation upstream. A cross
vane is primarily used for grade control and to protect the streambanks.
4.4.2 Root Wads
Root wads provide the following benefits: (1) protect the streambank from erosion; (2)
provide in-stream and overhead cover for fish; (3) provide shade, detritus, and terrestrial
insect habitat; (4) look natural, and (5) provide diversity of habitats (Rosgen 1996). A
footer log and boulder are placed on the channel bottom abutting the streambank along an
outside meander that will provide support for the root wad and additional stability to the
bank. A large tree root wad is then placed on the streambank with additional boulders and
rocks on either side for stability. Flowing water is deflected away from the bank and
towards the center of the channel. Specific location of these structures and types of
structures will be determined during final design.
4.4.3 Vegetated Geogrids/Brush Mattresses
Vegetated geogrids may be used in locations where space for root wads and other
structures is limited and where slopes are very steep. The primary application of
vegetated gcogrids will likely be along Canal Street. Vegetated geogrids use a hardened
38
e

East Tarboro Canal Restoration Platt
Edgecontbe Counry, NC
structure, such as a gabion basket or rock toe, for their base. Lifts of soil are wrapped in
a geotextile fabric and live cuttings are placed in-between individual lifts. The vegetative
stabilization provides soil reinforcement and aquatic habitat. Unlike a typical retaining
wall, the hardened look of this structure disappears once the overhanging vegetation is
established.
Brush mattresses are used to create a system of living branches that form a cover over the
streambank, providing immediate protection from erosion. These live stakes, cuttings,
and fascines root and grow into an excellent natural riparian zone habitat that works to
stabilize the banks. Brush mattresses will be used primarily on the steep banks along
Canal Street.
4.4.4 Stone Sills
A stone sill consists of boulders aligned perpendicular to the stream's flow so that the
header rock's top elevations are at the elevation of the proposed channel. The sill length
includes the bankfull to bankfull distance plus a portion embedded into each bank.
Individual rocks shall be fitted tightly such that water flows over the device and not
through the individual rocks. The header and footer boulders must be placed such that
the ends butt up against each other. No gaps between boulders will be accepted.
However, where voids occur between boulders due to the jagged surfaces, Structure
Stone, Class A shall be hand placed from both the upstream and downstream sides of the
structure to fill the voids.
After the structure is constructed, a trench shall be dug upstream along the outline of the
vane and sill rock. The trench shall extend to the bottom of the footer rocks. A non-
woven geotextile fabric shall be placed in the trench and backfilled with No. 57 Stone
(Sediment Control Stone). Fabric that overlaps the header rocks must be trimmed after
backfilling with stone, so that a maximum of 2 inches is exposed. Vegetation transplants
or live stakes shall be placed along the channel bank around the structure as detailed in
the Landscape Plans. Minor modifications to the structure may be necessary after water
has been returned to the channel.
4.4.5 Grade Control Vane
A grade control vane is essentially half of a cross-vane with the cross portion of the vane
extended into a sill. It redirects water in the downstream direction, thus reducing the near-
bank stresses. A grade control vane can be built in combination with rootwads and can
be built out of boulders or logs. Grade control vanes will be placed near the beginning of
meander bends to protect the steeper sloped banks along the outside of pools. Specific
location of these structures will be determined during final design.

5.0 HABITAT RESTORATION
5.1 Vegetation

East Tarboro Canal Restoration Plan
Edgecombe Countti•, NC
Vegetation that quickly develops a canopy, has an extensive root system, and a
substantial aboveground plant structure is needed to help stabilize the banks of a restored
stream channel in order to reduce scour and runoff erosion. In natural riparian
environments, pioneer plants that often provide these functions are alder, river birch,
silky dogwood, and various willow species. Once established, these trees and shrubs
create an environment that allows for the succession of other riparian species including
ashes, red maples, sycamores, and oaks.
In the newly restored stream channel, revegetation will be vital to help stabilize the
stream banks and establish a riparian zone around the restored channel. Revegetation
efforts on this project will emulate natural vegetation communities found along relatively
undisturbed stream corridors in ecologically similar settings. To quickly establish dense
root mass along the channel bank, a native herb/grass mixture will be planted on the
streambed and bank. Shrubs, vines, and live stakes will be utilized on the stream bank
and along the floodplain to provide additional root mass. Extra care will be given to the
outside of the meander bends to ensure a dense root mass in those areas of high stress.
Coir matting will be used to provide erosion protection until vegetation becomes
established. Trees, shrubs and a native grass mixture will be planted along the tops of the
channel banks.
In addition to the plantings to help stabilize the newly excavated stream banks, a
characteristic floodplain forest community will be reestablished in a riparian buffer zone
along each stream bank. Where possible the buffer will be 50 feet. Due to the urban
constraints in Reach 1, the buffer will extend from the top of bank to the road shoulder,
which is less than 50 feet on each side.
All plant material should be native species collected and propagated from material within
the Upper Coastal Plain physiographic province and within 200 miles north or south
latitude. The use of material that is genetically adapted to specific site conditions
enhances long-term growth and survival and avoids contaminating the gene pool of the
surrounding vegetation with non-adapted ecotypes. Vigorous growth of well-adapted
ecotypes can also minimize problems with exotic invasive plants. Appropriate plant
material is usually available upon request and can be obtained with planning and
foresight.
Woody vegetation will be planted between November and March to allow plants to
stabilize during the dormant period and set roots during the spring season. A non-
aggressive, rapidly germinating grass will be used for immediate temporary erosion
control on all newly excavated surfaces. A seed mix consisting of native graminoids and
43
East Tarboro Canal Restoration Plan
Edgecombe County, NC

forbs will be applied during the appropriate season to ensure optimal germination and
survival. Removal or control of nuisance vegetation will be implemented as necessary to
promote survival of target plants.
The floodplain community recommended for this project is modeled after tile Nyssa
(aquatica, biflora, ogeche) Floodplain Seasonally Flooded Forest Alliance (I.B.2.N.e.8)
as described in International Classification of Ecological Communities: Terrestrial
Vegetation (NatureServe 2002). This community is similar to the Coastal Plain Small
Stream Swamp (Blackwater Type) (Schafale and Weakley. 1990). Few indicator species
of this community are present on the site because of longstanding anthropogenic
alterations such as development and cultivation. However, the geography and topography
of the site match the characteristics of the target community. Recommended plantings
for this floodplain community are listed in the following sections. Dryer species are
recommended for the top of bank areas.
This restoration can be divided into two main types of restoration communities. The
upstream reach will require consideration of its location within a residential community
and the types of plantings that will be appropriate in this setting. The lower reach is in an
area with sufficient land to establish adequate buffers. This is also near a school and may
be used as a teaching tool for teachers, students, and community leaders.
5.1.1 Site Preparation
This restoration occurs within an urban setting and raising the streambed elevation to its
original elevation is not practical. Because a new floodplain will need to be excavated,
the underlying soil will need to be considered for fertility and compaction in relation to
establishing a vegetative cover. Existing topsoil shall be stockpiled on-site for later use.
It is recommended that topsoil be added to the newly excavated surface to provide more
favorable growing conditions that will allow quick establishment and growth of the
desired vegetation. Topsoil should be loamy and contain higher amounts of organic
material. The upper reach does not currently appear to have appropriate topsoil.
Therefore, topsoil from the lower reach or from an outside source may be required in this
area.
Liming and fertilizing are probably not necessary on this site, given the long history of
these treatments. Addition of nutrients and a pH greater than 6.0 will favor the growth of
ruderal opportunists over the desired native species. However, a soil analysis should be
performed to confirm nutrient status on the site. Any required soil amendments shall be
disked in.
Although exotics species are limited within the restoration reaches, these species are
upstream and adjacent to the site. Care should be taken to prevent invasion of these
species as most are relatively mobile and can establish rapidly under favorable
conditions.
44
East Tarboro Canal Restoration Plan
Edgccombe County, NC
All planting areas to be planted shall be ripped on contour to a minimum depth of 18
inches. A 2-inch layer of organic matter and other soil amendments, including topsoil,
fertilizer, and possibly lime, should be incorporated into the soil surface of planting areas
by disking. Addition of organic matter during site preparation is a fast, easy way to
shorten the time it will take for the soil to revert to a characteristic pre-disturbance
structure and chemistry supportive of bottotnland forests. Well-seasoned hardwood chips
or leaf compost may be used as a source of organic matter. Including organic matter on
the entire site may not be practical. However, it is recommended in the areas adjacent to
and including the newly built channel. The surface should be left rough and irregular to
emulate natural microtopography except where coir matting is to be placed which
requires a smooth surface free of irregularities for optimum performance.
5.1.2 Streambank Vegetation
A combination of seeds, live stakes, and bare root nursery stock will be utilized to
stabilize the banks. Species proposed for planting are listed below. Any of the listed
species may also be salvaged from construction areas and transplanted on the
streambanks.
Live stakes

5.1.3 Riparian Buffer
In Reach 2, a target 50 ft. riparian buffer will be established in the floodplain from the top
of the banks of the proposed stream channel. Bare-root seedlings of canopy and
subcanopy tree species will be planted on 8-foot centers for a planting density of 680
trees/acre of the finest quality 1/0 seedlings. Hardwood bare-root seedlings that will form
the canopy must have a minimum root collar diameter (RCD) of 3/8-inch. It is
recommended that seedlings be at least 12 to 18 inches in height. Proposed species to be
planted in these areas include the following:
Trees (bare root)
Swamp tupelo (1 vssa biflora)
Bald cypress (Taxodiwn dislichum)
Green ash (Fr(ixiriits peruts),lvattica)
Oaks (Quercus laurifolia, Q. nigra, Q. phellos, Q. pagoda)
Ironwood (Carpinus caroliniana)
Bitternut hickory (Carva cordiformis)
Shrubs should be concentrated along the outer edges of the buffer as a possible barrier to
opportunistic invasions of exotic species.
Shrubs (bare root or container)
American beautyberry (Callicarpa americana)
American hazelnut (Corti.lus americana)
Flowering dogwood (Corpus florida)
Grandizoids and Forbs
Deertongue (Panicum clandestinton)

6.0 MONITORING
The following monitoring criteria are taken from the Stream Mitigation Guidelines
(USACE, 2003) for Level 1 Restoration and Enhancement sites.
Monitoring of the stability of the channel is recommended to occur after the first growing
season and should continue annually for a period of 5 years or until two bankfull events
have been documented. Bankfull events must be documented during separate monitoring
years.
The following monitoring practices are recommended at all Level 1 Restoration and
Enhancement sites: reference photos, plant survival analysis, channel stability analysis,
and biological data if required by permit conditions. Channel stability analysis will
consist of a representative longitudinal profile, cross-sections, pebble counts at each
cross-section, and pattern measurements if altered since construction. The purpose of
monitoring is to determine bank stability, bed stability, morphological stability, overall
channel stability, and mortality of vegetation. If biological sampling is required, it will
be used to evaluate secondary impacts of the restoration project.
The monitoring report shall contain a general description of the site and the goals of the
project. The report will discuss the current years' results and a discussion of any changes
that have occurred on the restoration site. The relative significance of these changes will
be discussed in detail and a maintenance plan will be recommended if applicable. The
current data overlaid over the previous data and a photo log showing successive photos
will be included in the appendix.
7.0 SUCCESS CRITERIA
The following success criteria are recommended for the East Tarboro Canal Project.
These criteria are taken from the Stream Mitigation Guidelines (USACE, 2003).
7.1 Channel Stability
7.1.1 Dimension, Pattern, and Profile
The dimension, pattern, and profile of the stream should show no radical change during
the 5-year monitoring period. To determine this, the longitudinal profile and cross-
sections will be re-surveyed annually. Cross-sections will be overlaid to verify no
significant change in the dimension from year to year. Similarly, the longitudinal profile
will be overlaid to confirm a stable bed profile, i.e. riffle pool spacing should remain
fairly constant and there should be a general lack of aegradation and degradation. Due to
the number of rootwads located in the majority of the meanders, the pattern may be
47
s
B

? .i
East Tarboro Canal Restoration Plan
Edgecombe County, NC
confirmed through visual observation. If a rootwad has washed out or there are signs of
erosion, the radius of curvature will be measured and compared to the as-built mapping.
7.1.2 Bed Material
A Modified Wohnan Pebble Count will be taken at each cross-section to determine the
change in the surface material below bankfull. The pools should contain a finer material
than the riffles. In general, the pebble count should show a change in the size of bed
material toward the desired composition. The pebble count will be taken once a year
during the annual monitoring period. The consecutive pebble counts will be plotted on
the same graph. In addition, the D50 and D84 will be compared to determine changes in
the surface material of the cross-section.
7.2 Photograph Documentation
Photographs will be taken as described by the permit conditions and compared to the as-
built photos. The photos will be used to make a qualitative assessment of channel
aggradation or degradation, bank erosion, success of riparian vegetation, effectiveness of
erosion control measures, and the presence or absence of developing in-stream bars. Any
significant changes from the as-built conditions will be discussed and highlighted in the
report.
7.3 Ecological Function
Ecological function will be assessed to determine the health and survival of the
vegetation and to determine if the restored section mimics the reference reach. The
success criteria for tree seedlings in the riparian buffer zones are defined by the Division
of Water Quality to be 80 % survival of planted species or 260 trees/acre after five years.
Vegetation will be monitored annually.

1.0 PURPOSE AND SCOPE OF SERVICES
F&R has completed the subsurface exploration for the proposed East Tarboro Canal realignment
in Tarboro, North Carolina. F&R completed the subsurface exploration at the project site on
August 18, 2004. The purpose of this exploration was to evaluate the subsurface conditions near
the existing canal and within the general area of the proposed realignment and to provide general
recommendations with regards to creek bank stabilities. In order to achieve these purposes, we
performed the following scope of work:
• Performed a site reconnaissance to complete geotechnical observations;
• Reviewed relevant, readily available published geologic maps;
• Advanced 5 soil test borings within the project area;
li ' • Prepared typed Boring Logs and a Subsurface Profile;
• Assessed the collected information and prepared this report.
This report is organized to discuss the Project Data (Section 2.0), Exploration Procedures
(Section 3.0), Geologic & Subsurface Conditions (Section 4.0), General Engineering Evaluation
(Section 5.0). The drawings, and test boring logs are presented in the Appendices to this report.
2.0 PROJECT DATA
2.1 SITE DESCRIPTION

The subject property is located within the City of Tarboro, North Carolina (see Figure 1, Appendix
I) along the existing East Tarboro Canal. The existing canal currently runs parallel to West Canal
Street and then through a series of parks, open areas, and a school yard. In general, the nearby
ground surface is covered with grass and scattered pine trees.
The site elevations range between 10 and 14 feet above mean seal level (see Figure 2 - Boring
Location Plan). Large flat plains are typical topographic features of the surrounding area and the
site itself is relatively flat. The project vicinity is developed with residential homes, parks, schools
and small businesses.

2.2 PROPOSED CONSTRUCTION
SINCE
t??t®
The proposed project will consist of the realignment of the existing canal, creating a more natural
meandering stream. Final grading plans and stream alignments were not available at the time of
explorations or the preparation of this report. F&R is not aware of any structures or cuts and fills
of significant depth associated with this project.
3.0 EXPLORATION PROCEDURES
A total of five (5) soil test borings (B-1 through B-5) were performed at the project site. The
borings were advanced at the approximate locations shown on the attached Boring Location Plan
included as Figure 2 in Appendix I. The boring locations were established in the field with the
assistance of Mr. John Nichols of Earth Tech. Ground surface elevations at the boring locations
have been interpolated from topographic map (USGS 7.5 Minute Series, Tarboro Quadrangle) and
should only be considered approximate given the method of determination.
Each boring was advanced to a depth of 15 feet below the ground surface utilizing hollow stem
auger boring techniques for borehole stabilization. Representative soil samples were obtained using
a standard two-inch outside diameter (O.D.) split barrel sampler in general accordance with ASTM
D 1586, Penetration Test and Split-Barrel Sampling of Soils (Standard Penetration Test). T
number of blows required to drive the split barrel sampler three consecutive 6-inch increments
recorded and the blows of the last two 6-inch increments are added to obtain the Stands
Penetration Test (SPT) N-values representing the penetration resistance of the soil.
Penetration Tests were performed at frequent intervals to evaluate the consistency and
engineering properties of the subsurface soils.
Representative portions of the soil samples obtained from each SPT interval were sealed in a
container, labeled and transported to our laboratory for final classification by a geotechnical
engineer. The soil samples were visually classified in general accordance with the Unified Soil
Classification System (USCS), using visual-manual identification procedures (ASTM D 2488). The
Boring Log for each test boring is presented in Appendix 11 of this report.

4.0 GEOLOGIC AND SUBSURFACE CONDITIONS
4.1 REGIONAL GEOLOGY
' The project site is geologically located within the Coastal Plain Physiographic Province of North
Carolina. The Coastal Plain of North Carolina is comprised of flat lying to very gently dipping
sedimentary strata which overlay a "basement" of crystalline rocks. The site is specifically
located within the Yorktown Formation (Tpy). This formation is described as fossiliferous clay
with varying amounts of fine grained sand, bluish gray, shell material commonly concentrated in
lenses, mainly in areas north of the Nuese River (Brown, 1985).
4.2 SUBSURFACE CONDITIONS
A Subsurface Profile has been prepared from the boring data to graphically illustrate the
subsurface conditions encountered at the site and is presented as Figure 3. Strata breaks
designated on the Boring Logs and Subsurface Profile represent approximate boundaries
between soil types. The transition from one soil type to another may be gradual or occur
between soil samples. This section of the report provides a general discussion of subsurface
conditions encountered within areas of proposed construction at the project site during our
subsurface exploration. More detailed descriptions of the subsurface conditions are presented on
the Boring Logs in Appendix H.
Soil conditions in Borings B-1, B-2 and B-3 were similar to each other, while B-4 and B-5 were
similar. Each boring encountered a relatively thin layer of organic topsoil, between 0.2 feet in
thickness, consisting of dark brown loamy soils with roots and rootlets.
i
Underlying the topsoil, Borings B-1, B-2 and B-3 encountered loose to medium dense, mixed
brown sand with varying amounts of silt to depths between 1.5 to 6.0 feet. SPT N-values ranged
between 4 and 7 bpf (blows per foot). Beneath this layer, very loose to medium dense, mixed
brown clayey sands were encountered to depths between 8.5 and 15.0 feet below the ground
surface. SPT N-values ranged between 2 and 11 bpf, with typical values of 6 bpf. B-2 was
terminated in this formation at a depth of 15.0 feet. Borings B-1 and B-3 then encountered loose,

with typical values of 7 bpf.
i
SPT N-values ranged from 6 to 15 bpf,
Borings B-4 and B-5 encountered a slightly different soil profile from B-l, B-2 and B-3. B-4
penetrated a relatively thin layer of firm, mixed brown and gray, sandy silt to a depth of 1.5 feet.
The blow counts in this layer were 6 bpf. From just below the topsoil layer in B-5, and
underlying the sandy silt in B-4, each boring penetrated stiff, mixed gray clay with varying
amounts of sand. SPT N-values ranged in this layer from 12 to 15 bpf with typical values of 12
bpf. A relatively thin layer of sandy clay underlies the silts which was found to be soft, gray and
brown. SPIT N-values within this soil layer were 3 bpf. Each boring was terminated in a very
loose to medium dense gray and green sand which contains variable amounts of silt and clay.
SPT N-values varied between 11 bpf in B-4 and 2 bpf in B-5.
4.3 GROUNDWATER CONDITIONS
Soil samples were generally found to be in a moist condition, however, all samples retrieved from
below the groundwater table were saturated. Free-standing groundwater was encountered between
approximately 4.0 to 7.0 feet below the ground surface in all borings. Measurements were taken
immediately after drilling. Borings were backfilled upon completion of drilling. We note that the
elevation of the groundwater table is dependent upon seasonal factors such as precipitation and
temperature as well as the depth of water in the nearby canal. Therefore, the elevation of the
groundwater table may be different at other times of the year from the elevation presented in this
report.
5.0 GENERAL ENGINEERING EVALUATION
' The soils encountered in the borings that will form the new stream banks predominantly consist of
loose sands, soft clays, and stiff silts. Based on the estimated stream bed elevations, it is anticipated
that the stream bed will consist of different combinations of these soils.
Due to the apparently loose and soft condition of the native sands and clays, F&R recommends that
the stream banks within sandy areas generally be graded no steeper than 3 Horizontal to 1 Vertical
(3H:1 V) for slope stability considerations. In locations with the stiff silts (B-4 and B-5) the stream

banks may be increased to 2.5 Horizontal to I Vertical (2H: IV) if required. However, it should be
understood that minor sloughing may occur in areas of steeper slopes.
Following excavation, the slopes should be vegetated as soon as possible to stabilize the surface and
prevent erosion and surface sloughing. It is our understanding that the type of vegetation and
method of placement will be determined by Earth Tech. Slopes which are not adequately vegetated
and stabilized may be more susceptible to sloughing and erosion, which may then require
maintenance.
Please do not hesitate to contact us if you have any questions regarding this report or require
additional geotechnical information.
6.0 MUTATIONS
This report has been prepared for the exclusive use of Earth Tech for specific application to the
referenced property in accordance with generally accepted soil and engineering practices. No other
warranty, expressed or implied, is made. These conclusions and recommendations do not reflect
variations in subsurface conditions that could exist intermediate of the boring locations or in
unexplored areas of the site. Should such variations become apparent during construction, we
reserve the right to re-evaluate our conclusions and recommendations based upon on-site
observations of the conditions. In the event changes are made in the proposed construction plans,
the recommendations presented in this report shall not be considered valid unless reviewed by our
firm and conclusions of this report modified or verified in writing. Prior to final design, F&R
should be afforded the opportunity to review the project plans and specifications to determine if
additional or modified recommendations are necessary.
