Bethabara Road Emergency Repair (SAW-2019-00697)
Winston-Salem, North Carolina

Dear Mr. Roden-Reynolds:
The City of Winston-Salem (City) has experienced impacts to City infrastructure as a result of stream
channel erosion causing a roadway embankment to fail, compromising the safety of the traveling public.
The City intends to stabilize and realign the stream channel away from the eroded roadway embankment
to reestablish the roadway shoulder. The Project Site includes 0.85 acres located along the south side of
Bethabara Road from Hickory Glen Road to the confluence of Monarcas Creek in Winston-Salem, North
Carolina (Figures 1 and 2).
On behalf of our client, the City of Winston-Salem, HDR Engineering, Inc. (HDR), is requesting
authorization under a Nationwide Permit (NWP) 27 (Aquatic Habitat Restoration, Establishment, and
Enhancement Activities) for activities associated with the Bethabara Road Emergency Repair in Winston-
Salem, Forsyth County (Figures 1 and 2). A utility line crossing under NWP 12 (Utility Line Activities) and
bank stabilization under NWP 13 (Bank Stabilization) are also proposed for this project, but would be
considered automatically authorized as both activities do not trigger pre-construction notification.

Project Background
On March 7, 2019, HDR scientists reviewed the Project Site for Waters of the U.S. under Section 404 of
the Clean Water Act. Jurisdictional waters were delineated according to the methodology and guidance
described in the U.S. Army Corps of Engineers (USACE) 1987 Wetland Delineation manual, USACE
Post-Rapanos guidance, and the 2012 USACE Eastern Mountains and Piedmont Regional Supplement
(Version 2.0). A number of resources were also utilized including U.S. Geological Survey (USGS)
topographic maps (Figure 2), aerial imagery (Figure 3), and Natural Resources Conservation Service
(NRCS) Soil Survey (Figure 4). A Preliminary Jurisdictional Determination Verification was issued on May
9, 2019 (Figure 5, Table 1, and SAW-2019-00697, attached). The on-site surface waters drain to and
include Monarcas Creek which is located in the Upper Yadkin River Basin (HUC 03040101). Monarcas
Creek is classified as Class C Waters by the North Carolina Department of Environmental Quality –
Division of Water Quality.

Project Description
The Bethabara Road Emergency Repair will consist of stream enhancement utilizing natural channel
design techniques. Stream enhancement activities will occur along the entire length of Tributary 2
beginning at the existing 48-inch corrugated metal pipe (CMP) beneath Hickory Glen Road and ending at
the confluence to Monarcas Creek. The existing culvert will be left in-situ. In order to accommodate the
new channel location, a portion of the existing sewer line will be relocated further to the south (Figures 6
and 7). Proposed enhancement activities include channel relocation, bank grading and stabilization,
floodplain bench excavation, installation of in-stream structures, and establishment of a riparian buffer.
Purpose and Need for the Project
Currently, the southern road embankment of Bethabara Road is failing as the result of stream channel
erosion (Photographs 1 and 2 on Figure 5). The stream channel has cut into the toe of slope along the
road and the embankment has sloughed off, resulting in the loss of the road shoulder. The stream banks
are in an unstable condition and are subject to mass wasting and excessive erosion in many places,
causing excessive sediment inputs into the stream and the subsequent failure of the road embankment.
The existing channel is also incised and lacks a connection to an active floodplain. This road
embankment failure, due to excessive stream erosion, poses a serious safety threat for the traveling
public. The road embankment will need to be rebuilt to support the road.
The current alignment of Tributary 2 is abutting the toe of slope of the road and in order to rebuild the
road embankment, the channel requires a realignment to the south to provide adequate area for the road
embankment rebuild. Therefore, the purpose of the project is to realign Tributary 2 south, away from the

Pre-Construction Notificaiton Pursuant to Nationwide Permit Nos. 12, 13, and 27

3 | P a g e

road, utilizing natural channel design techniques to enhance approximately 409 linear feet (lf) of the
existing 423 lf channel.
Two constraining factors considered in the design include the need to provide area for the road
embankment rebuild and the location of an existing sewer line south of Tributary 2. Essentially, the
channel is located between the road and the sewer line. To work within these constraints and also meet
the purpose and need of the project, a net loss of 14 lf of channel is anticipated during the channel
relocation.
Natural channel design techniques include reconnecting Tributary 2 to its relict floodplain where possible,
and to restore a stable pattern, profile, and cross-section. In-stream structures will be used to provide
grade control and to enhance habitat diversity within the channel. Bioengineering techniques such as live
staking and coir fabric for bank stabilization will be used to enhance stream bank stability, thus reducing
sediment inputs.
No mitigation credits are being proposed.
Avoidance and Minimization
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent possible.
Proper sediment and erosion control measures will be used to minimize disturbances to downstream
waters. A pump around will be utilized to ensure that all work is conducted in the dry. The project will
comply with all FEMA requirements and NWP Regional and General Conditions.
No impacts to wetlands will occur.
Alternatives Analysis
A no-build alternative was considered, but was deemed impracticable. To not fix the failing road
embankment could result in serious injury to vehicular travelers. Therefore, a build option is necessary.
Two build options were considered and are discussed below.
Alternative 1
The first alternative considered was to construct a tiered, gabian wall along the entire south side of
Bethabara Road to create a road shoulder. The gabian wall would extend to the toe of slope and would
effectively be the right bank of Tributary 2. The bed and banks would not be altered and this alternative
would not result in any permanent loss of waters of the US; however, the channel would not receive the
beneficial enhancement activities for aquatic uplift that the chosen alternative proposes. Moreover, this
option is cost prohibitive as the estimated costs of installing the gabian wall exceed that of the estimated
total costs to realign the channel using natural channel design techniques, to relocate the sewer, and to
rebuild the road embankment. Therefore, this alternative was eliminated from further consideration.
Alternative 2 (Preferred Alternative)
The preferred alternative proposes to relocate the existing channel to the south, away from the failing
road embankment (Figures 6 and 7). Relocating the channel away from the road will provide the space
needed to reconstruct the road embankment and provide the necessary reinforcement to prevent failure
in the future. This alternative proposes a constructed riffle with a log sill for grade control at the outfall of
the existing CMP at Hickory Glen Road. Rip rip will be placed and keyed in around the culvert and along
the left bank for the length of the constructed riffle, but above the OHWM, resulting in no impact. There
are also four double drop rock vanes located throughout the relocated channel and a rock step pool
structure is also proposed to step the channel grade down to Monarcas Creek. Finally, a log sill will be

Pre-Construction Notificaiton Pursuant to Nationwide Permit Nos. 12, 13, and 27

4 | P a g e

installed on the left bank of Monarcas Creek to stabilize the bank to protect the confluence of Tributary 2.
The log sill on the left bank of Monarcas Creek will not be greater than one cubic yard per running foot
below the OHWM. A rip rap toe will be installed along the length of the repaired road embankment. This
rip rap will be outside the OHWM of the creek and will not result in impacts to Jurisdictional Waters.
An existing sewer line is located south (or parallel to the left bank) of existing Tributary 2. A portion of the
sewer line will be relocated further south, creating the space needed to relocate the channel away from
the failing road embankment. The sewer relocation will necessitate a sewer crossing across Tributary 2
that will occur within the same footprint of the constructed riffle, just downstream of the existing CMP
outfall at Hickory Glen Road. No permanent impacts will result from this sewer crossing.
Proposed Impacts to Jurisdictional Waters
Nationwide 12 (Utility Lines)
A portion of an existing sewer line is proposed to be relocated further south to provide the spatial area to
relocate the channel away from the failing road embankment (Figures 6 and 7). The sewer line will be
relocated and tied into an existing manhole located in the western portion of the project. Due to
easement constraints, the relocated sewer line will necessitate one crossing of Tributary 2 in the same
footprint as the proposed constructed riffle that will occur under NWP 27 (described below). Any impacts
associated with the sewer line crossing are temporary and because the utility crossing will occur in the
same footprint as the constructed riffle proposed for stream enhancement, will be reported under NWP
27.
Nationwide 13 (Bank Stabilization)
Under Nationwide 13, a 35 foot log sill is proposed to be installed on the left bank of Monarcas Creek to
stabilize the bank to protect the confluence of Tributary 2 (Figures 6 and 7). The log sill on the left bank of
Monarcas Creek will not be greater than one cubic yard per running foot below the OHWM and is
therefore automatically authorized under NWP 13.
Nationwide 27 (Aquatic Habitat Enhancement)
The City proposes to enhance approximately 409 lf of jurisdictional stream. The proposed stream
enhancement will necessitate the filling of approximately 423 lf of existing, degraded stream channel and
the building 409 lf of stream channel (Figures 6 and 7). The proposed restored stream channel is
approximately 409 lf in length, resulting in a net loss of 14 lf of stream channel. No wetlands will be
impacted by the proposed activities. A complete construction plan set (attached), including plan, profile,
and cross section for the proposed channel is also attached.
Natural channel design techniques were selected for this project based on the existing conditions and on-
site constraints. Stream bed and bank stabilization and realignment is proposed for Tributary 2 due to is
constraining location between Bethabara Road and the existing sewer line which limited the ability to
improve the pattern of the channel. Published reference reach data were used to generate design criteria
for the proposed activities. Figure 6 illustrates the proposed alignment for the channel relocation and
enhancement activities along with the proposed impacts to the existing stream channel. The proposed
impacts to Tributary 2 total 423 lf of stream channel. The proposed new channel will be 409 lf, resulting in
a net loss of 14 lf of stream channel.
The existing degraded channel will be filled in and approximately 409 lf of stream will be established and
reconnected to its original floodplain. The existing 48” corrugated metal pipe (CMP) at Hickory Glen Road
will remain in-situ and the confluence to Monarcas Creek will be maintained because the stream profile is
designed to tie in to the invert of the CMP and invert of the confluence. A reference reach database of

North Carolina piedmont stream channels was used to develop design criteria for channel dimension,
pattern, and profile. A cross-sectional area was developed to accommodate sediment load and stabilize
the stream banks. In-stream structures will be installed to stabilize stream bed and bank and to enhance
aquatic habitat. Channel dimensions and stream profile were verified using hydrologic modelling
techniques.
The improvements planned for Tributary 2 will adjust the alignment to relocate the stream channel away
from the road, and establish a bankfull floodplain channel. Biodegradable, coconut matting with a native
riparian seed mix will be used to stabilize the banks once grading is complete. Silky dogwood (Cornus
amomum), silky willow (Salix sericea), and elderberry (Sambucus canadensis) will be used as live stakes
to establish native woody species on the newly graded and matted bank and a native, riparian seed mix
will also be used. (Construction Planset, attached).

HDR also queried the North Carolina Natural Heritage Program (NCNHP) Data Explorer database for
protected species Element Occurrence distribution and proximity to the Project Site (Project Report
[NCNHDE-8960], attached). The query revealed that no known occurrences of federally protected
species or critical habitat have been documented within a one-mile radius of the Project Area.
HDR conducted an on-site visit and determined that the project site does not exhibit habitat for bog turtle
or small-anthered bittercress. It was also determined that potential summer roosting habitat for the NLEB
is present in forested areas of the site. Therefore, the project was also reviewed in accordance with the
northern long-eared bat (NLEB) Standard Local Operating Procedures for Endangered Species
(SLOPES) between the USACE, Wilmington District, and the Asheville and Raleigh U.S. Fish and Wildlife
Service (Service) Offices. It was determined that the project is located is more than 0.25 miles away from
HUCs with documented hibernacula and activities in the project limits do not require prohibited incidental
take; as such, this project meets the criteria for the 4(d) rule and any associated take is
exempted/excepted. As established in the NLEB SLOPES, this project does not require prohibited
intentional take of the NLEB and it meets the criteria for the 4(d) rule.
The proposed Project is not anticipated to have an effect on any federally protected species.
Compensatory Mitigation
This project will result in a net loss of stream channel (14 linear feet), but will provide an improvement in
stream quality and stability. Therefore, no compensatory mitigation is proposed for this project. However,
the City would like to propose the establishment of photographic monitoring points along the channel to
monitor the channel enhancement. The City will provide annual monitoring photographs along with a
short letter describing channel conditions for a period of three years post-construction.

D. Impact Justification and Mitigation

1. Avoidance and Minimization

1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Alternatives Analysis
A no-build alternative was considered, but was deemed impracticable. To not fix the failing road embankment could result in
serious injury to vehicular travelers. Therefore, a build option is necessary. Two build options were considered and are
discussed below.

Alternative 1
The first alternative considered was to construct a tiered, gabian wall along the entire south side of Bethabara Road to create a
road shoulder. The gabian wall would extend to the toe of slope and would effectively be the right bank of Tributary 2. The bed
and banks would not be altered and this alternative would not result in any permanent loss of waters of the US; however, the
channel would not receive the beneficial enhancement activities for aquatic uplift that the chosen alternative proposes.
Moreover, this option is cost prohibitive as the estimated costs of installing the gabian wall exceed that of the estimated total
costs to realign the channel using natural channel design techniques, to relocate the sewer, and to rebuild the road
embankment. Therefore, this alternative was eliminated from further consideration.

Alternative 2 (Preferred Alternative)
The preferred alternative proposes to relocate the existing channel to the south, away from the failing road embankment
(Figures 6 and 7). Relocating the channel away from the road will provide the space needed to reconstruct the road
embankment and provide the necessary reinforcement to prevent failure in the future. This alternative proposes a constructed
riffle with a log sill for grade control at the outfall of the existing CMP at Hickory Glen Road. Rip rip will be placed and keyed in
around the culvert and along the left bank for the length of the constructed riffle, but above the OHW M, resulting in no impact.
There are also four double drop rock vanes located throughout the relocated channel and a rock step pool structure is also
proposed to step the channel grade down to Monarcas Creek. Finally, a log sill will be installed on the left bank of Monarcas
Creek to stabilize the bank to protect the confluence of Tributary 2. The log sill on the left bank of Monarcas Creek will not be
greater than one cubic yard per running foot below the OHWM. A rip rap toe will be installed along the length of the repaired
road embankment. This rip rap will be outside the OHWM of the creek and will not result in impacts to Jurisdictional Waters.
An existing sewer line is located south (or parallel to the left bank) of existing Tributary 2. A portion of the sewer line will be
relocated further south, creating the space needed to relocate the channel away from the failing road embankment. The sewer
relocation will necessitate a sewer crossing across Tributary 2 that will occur within the same footprint of the constructed riffle,
just downstream of the existing CMP outfall at Hickory Glen Road. No permanent impacts will result from this sewer crossing.

1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent possible. Proper sediment and
erosion control measures will be used to minimize disturbances to downstream waters. A pump around will be utilized to ensure
that all work is conducted in the dry. The project will comply with all FEMA requirements and NWP Regional and General
Conditions. No impacts to wetlands will occur.

Definitions of Federal Status Codes:
E = endangered. A taxon "in danger of extinction throughout all or a significant portion of its range."
T = threatened. A taxon "likely to become endangered within the foreseeable future throughout all or a
significant portion of its range."
C = candidate. A taxon under consideration for official listing for which there is sufficient information to support
listing. (Formerly "C1" candidate species.)
BGPA =Bald and Golden Eagle Protection Act. See below.
ARS = At Risk Species. Species that are Petitioned, Candidates or Proposed for Listing under the Endangered
Species Act. Consultation under Section 7(a)(2) of the ESA is not required for Candidate or Proposed species;
although a Conference, as described under Section 7(a)(4) of the ESA is recommended for actions affecting
species proposed for listing.
FSC=Federal Species of Concern. FSC is an informal term. It is not defined in the federal Endangered Species
Act. In North Carolina, the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service)
define Federal Species of Concern as those species that appear to be in decline or otherwise in need of
conservation and are under consideration for listing or for which there is insufficient information to support
listing at this time.Subsumed under the term "FSC" are all species petitioned by outside parties and other
selected focal species identified in Service strategic plans, State Wildlife Action Plans, or Natural Heritage
Program Lists.
T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance
https://www.fws.gov/raleigh/species/cntylist/forsyth.html 1/2

5/13/2019 Forsyth County Endangered Species, Threatened Species,Federal Species of Concern, and Candidate Species
with another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered
or threatened and are not subject to Section 7 consultation. See below.
EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental,
nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land,
for consultation purposes, and as species proposed for listing on private land.
P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT",
respectively.
Bald and Golden Eagle Protection Act (BGPA)_
In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de-
listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007.
After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the
primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a
statutory definition of "take" that includes "disturb". The USFWS has developed National Bald Eagle
Management Guidelines to provide guidance to land managers, landowners, and others as to how to avoid
disturbing bald eagles. For mor information, visithttp://www.fws.gov/migratorybirds/baldeagle.htm
Threatened due to similarity of appearance(T(S/A))_
In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New
York south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to
Georgia) was listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the
collection and interstate and international commercial trade of bog turtles from the southern population. The
T(S/A) designation has no effect on land management activities by private landowners in North Carolina, part of
the southern population of the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife
Service considers the southern population of the bog turtle as a Federal species of concern due to habitat loss.
Definitions of Record Status:
Current - the species has been observed in the county within the last 50 years.
Historic - the species was last observed in the county more than 50 years ago.
Obscure - the date and/or location of observation is uncertain.
Incidental/migrant - the species was observed outside of its normal range or habitat.
Probable/potential - the species is considered likely to occur in this county based on the proximity of known
records (in adjacent counties), the presence of potentially suitable habitat, or both.

RE. Bethabara Rd Emergency Repair
Dear Jessica Tisdale.
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database indicates that
there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary. Please note that although there
may be no documentation of natural heritage elements within the project boundary, it does not
imply or confirm their absence, the area may not have been surveyed. The results of this query
should not be substituted for field surveys where suitable habitat exists. In the event that rare
species are found within the project area, please contact the NCNHP so that we may update our
records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of
the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for
guidance. Contact information for USFWS offices in North Carolina is found here:
httr)s://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund
easement, or Federally -listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod nev.butlerWncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program
