Dear Sir:

The North Carolina Department of Transportation (NCDOT) requests modification to the existing Section
404 Individual Permit and Section 401 Water Quality Certification for the proposed Winston Salem
Northern Beltway from US 52 to US 311 (TIP U-2759 D, E, and F) in Forsyth County. This project is
currently under construction.

This modification will result in no changes to wetland impacts previous documented. It will result in 31
linear feet of additional permanent stream fill impacts and 20 linear feet of additional temporary stream
impacts. The total project impacts for U-2579D, E, and F include 12,111 linear feet of permanent stream
impacts of which 405 linear feet is bank stabilization, 615 linear feet of temporary stream impacts, 1.66
acres of permanent wetland impacts, no temporary wetland impacts, and no hand clearing in wetlands.

Please see the enclosed revised permit drawings and updated impact summary sheets which reflect the
changes in impacts.

Permit Impact Site Modification

Site 18A (Roadway Plan Sheet 20): Site 18A impacts changed as a result of the decision to remove a 24”
reinforced concrete pipe (RCP) located to the south of the Winston Salem Northern Beltway roadway
alignment and to the west of Phelps Drive (Y6C). The parcels (5 total) where Stream ES-S68 (UT to Mill
Creek) and the existing 24” RCP are located were obtained by NCDOT during the right of way process.
Access to the parcel is being removed along with the homes and sheds that occurred on the parcel(s).
This site was reviewed for onsite mitigation potential; however, due to a number of constraints, it was
determined that the best solution was to remove the 24” RCP and replace it with a standard base ditch
with embedded rip rap. The main constraint and reason to use the standard base ditch is due to the steep
slope of the channel. There will be 20 linear feet of temporary impacts at this location in order to dewater
the existing stream around during construction. Removal of the 24” RCP will result in 141 linear feet of
channel being daylighted. There will be 7 linear feet of permanent bank stabilization impacts to the
channel beyond the pipe to tie the channel in at the inlet location and 24 linear feet of permanent impact
to correct the existing scour and tie at the pipe outlet. No additional impacts will occur at this site.

Site 26 (Roadway Plan Sheets 24/25): Site 26 impacts have not changed from the modification dated
January 2020; however, the design has changed due to the noise walls. A ditch is required along the toe
of fill that will tie to the existing bank stabilization at the inlet of ES-S24. The updated plan sheets are
attached.

Compensatory Mitigation

At site 18A, compensatory mitigation is proposed for the 24’ of new linear feet of permanent impacts to
correct the existing scour and tie at the pipe outlet. No compensatory mitigation is proposed for the 7’ of
permanent bank stabilization impacts. Table 1 below illustrates the current summary of stream impacts
requiring mitigation which has changed since the last permit modification request dated October 17, 2019.

1.0 BASELINE INFORMATION
The project is located within USGS Hydrologic Cataloging Unit 03040101, and NC Division of
Water Resources (NCDWR) sub-basin 03-07-04 of the Yadkin Pee-Dee River Basin, and is part
of the of the South Atlantic-Gulf region. The potential mitigation site is located along and to the
west of Phelps Drive approximately 0.35 mile east of Baux Mountain Road in Forsyth County on
the north side of Winston-Salem, on land that was purchased by the North Carolina Department
of Transportation (NCDOT). The project is within the Piedmont physiographic province,
specifically near the line between the Northern Inner Piedmont and the Southern Outer Piedmont
Ecoregions. Land use within the watershed is primarily residential development, forested areas,
and agricultural. The existing stream length, drainage area, and jurisdictional status are
summarized in Table 1.

The project includes analyzing the feasibility of restoration, enhancement, and preservation of an
unnamed tributary (UT) to Mill Creek as well as enhancement and restoration to areas along Mill
Creek. Mill Creek has been assigned Stream Index Number12-94-7 (NCDWR 2020) and is
designated a warm water stream with a classification of C. Class C waters are protected for
secondary recreation, fishing, and aquatic life.

Most of the native plant communities have been removed from the site as the area has been
mowed and maintained for the nearby residence and outbuildings which have now been removed
through NCDOTs acquisition of the property.
NCDOT is analyzing the potential for on-site mitigation for jurisdictional stream impacts
associated with Transportation Improvement Program (TIP) U-2579DEF as part of the
construction of the Winston-Salem Northern Beltway. The project would serve as on-site
mitigation through the restoration, enhancement, and preservation of 705 linear feet of streams if
deemed feasible.
2.0 SITE SELECTION
TIP U-2579 DEF involves construction of the Winston-Salem Northern Beltway from US 52 to
US 311 (New Walkertown Road). The stream restoration, enhancement and preservation site
was selected due to its location within the U-2579DEF corridor and NCDOTs purchase of the
property related to the project. The potential mitigation area includes approximately 1.5 acres
within a Right of Way held by NCDOT. Within this area, the NCDOT reviewed the potential for
restoration of the UT to Mill Creek, restoration of Mill Creek at the crossing of Phelps Dr, and
enhancement along Mill Creek. These options are referred to as options 1, 2 and 3, respectfully.
These options are summarized in table 2.
3.0 OPTIONS REVIEWED
Option 1: Restoration of Unnamed Tributary to Mill Creek
The existing UT to Mill Creek begins immediately downstream of a 24” pipe within the footprint
of the U-2579DEF road construction project. The UT extends over 600 lf from this point to
where it ties to Mill Creek. The far upstream extent of the UT is marked by severe channel and
floodplain incision immediately downstream of the 24” pipe where the channel begins. From
this point, moving downstream, the floodplain begins to widen allowing the channel some
meander pattern progressing south toward Mill Creek. Around the midway point along the UT,
the channel proceeds through another 24” reinforced concrete pipe for 141 lf.
Approximately 180 lf of the upper portion of the UT will be filled in by the new roadway facility
(permit site 18). Extensive Class I Rip Rap outlet protection is called for in the construction
plans to address stability concerns due to a 42” cross pipe and 18” pipe system outlet at this
location. This mitigation feasibility analysis reviewed restoring the UT to a natural channel
design from the terminus of the existing impact at permit site 18 to the tie in with Mill Creek.
The feasibility analysis reviewed three options for the Unnamed Tributary to Mill Creek. These
are referred to as Options 1a, 1b, and 1c below.
• Option 1a proposes to remove 141 ft of existing 24” pipe and Provide full restoration of the
UT to Mill Creek by grading a new floodplain, installing a number of grade control structures
and steps to stabilize the channel, and plantings. See Figures 1 thru 3.
Page 3 of 7

• Option 1b incorporates restoration, enhancement, and preservation of UT to Mill Creek. This
option attempts to strike a balance between the costs of full restoration and obtaining
mitigation credits. See Figures 4 thru 6.
• Option 1c, is based on removing 141 linear feet of existing 24” pipe and replacing it with a
standard base ditch with embedded riprap for stability. This option does not propose
mitigation credits for this work. Instead, it avoids a potential issue with the existing pipe in
the future by removing it prior to access being removed or restricted. See Figures 7 and 8.

Issues Discovered with Options 1a and 1b
The feasibility analysis has several constraints which would make options 1a and 1b appear cost
prohibitive on the UT to Mill Creek. These challenges include long term stability, grade control,
cost associated with necessary cut to achieve adequate floodplain, and buffer limitations due to
utility easements.
Stability and Grade Control Concerns: First and foremost was the channel slope which is 3.8%
or more specifically the UT to Mill Creek drops 19 feet in elevation over 500 feet in length. In
order to address that slope and provide full restoration on the UT to Mill Creek would take
significant grading and a significant number of structures in order to stabilize the channel.
Because of the slope of the channel, there is also a high potential for head cutting if any proposed
structures were to fail within the restored channel. There is an approximately 8 foot drop to get
from the UT elevation in the floodplain to the elevation of Mill Creek which poses a challenge
for stability and would require a substantial structure and some grading if you left the channel at
existing grade and simply tried to tie it in at Mill Creek. Even by doing that there is still a steep
grade on the channel which would require a number of structures to stabilize the channel.
The existing 24” pipe to be removed has a slope of 2.5%. As shown in the profile drawing
(Figure 6), there is notable drop-down in channel elevation as water enters the inlet side of the
pipe. At the outlet end there is a 2’ drop from pipe outlet to channel bottom. This outlet drop is
stabilized by a small concrete pad.
Grade control structures would be needed for stability of the channel and prevention of potential
head-cutting in the channel. In addition, the new channel will need to be steeper than existing
pipe to avoid drastic elevation changes at the upstream and downstream ends. As seen in profile
drawings for Options 1a and 1b (Figures 3 and 6) the longitudinal slopes would need to be 3.5-
4% to better tie with the channel upstream and limit amount of grade change at the downstream
end. Grade control needs to be achieved through the use of rock cross vanes. These have been
shown on the mitigation plan drawings for Options 1a and 1b (Figures 1 and 4).
With the amount of grade change in this section, as well as the overall site, trying to achieve any
riffle-pool sequence would be problematic as the riffle sections would need to be very short in
Page 4 of 7

length and severely steep. Therefore a typical section resembling that of a constructed riffle with
adequately sized stone to be embedded to channel depth would be required.
At the locations noted on Figures 4 and 7, the existing channel braids with some channel flow
accessing the floodplain of Mill Creek. If we were to take this channel offline we would face
challenges with grade change and tying a new channel into Mill Creek in a stable fashion.
Floodplain Concerns: In addition to the slope and stability issues noted above, another item that
is of concern creating and maintaining the floodplain.
In the full restoration option (Option 1a) floodplain would need to be created due to channel
elevations and topography. For studying the feasibility of this option we set the longitudinal
grade by mirroring the existing channel grade for the UT and then stepping the proposed channel
down after reaching the top of bank for Mill Creek (See Figure 3, profile). Proceeding in this
fashion kept the longitudinal grade as low as possible (aided by drop structures near pipe
removal) and limited the amount of floodplain excavation needed. Even still, we estimated
approximately 1060 CY of grading.
Another concern is with potential backwater impacts to the channel that could occur due to high
flows in Mill Creek. As mentioned above about stepping a new channel down to tie back in with
Mill Creek, we would need to accomplish this with grade controls structures. There would be
potential for these to degrade or fail due to effects of higher flows in Mill Creek.
Other unanticipated impacts that could occur include potentially impacting wetlands that exist in
the floodplain of Mill Creek that were not previously mapped as jurisdictional to the west of the
existing tributary.
Option 2: Restoration to Mill Creek at Phelps Drive
The two options reviewed at the crossing of Phelps Drive included restoration using natural
channel design (option 2a) and stabilizing with conventional means as approved in the permit
application (option 2b).
Option 2a: Option 2a includes restoration along Mill Creek where the existing culvert will be
removed using natural channel design methods. The intent would be to lay back the slopes and
remove the existing roadbed/fill to accomplish this. The slopes would be matted and planted
with livestakes. The existing scour hole would be filled in and banks repaired to tie in with the
new opening from removal of the culvert and the existing channel downstream. The goal would
be to install a minimum of two structures to assist in stabilizing the channel grade where the
culvert is removed and scour hole is repaired. There would not be any relocation of the channel
with this option.
Option 2b: Option 2b includes removal of the existing culvert and stabilizing the area with riprap
as detailed and illustrated in the permitted plans.
Page 5 of 7

Issues Discovered with Options 2a
The main issue discovered when analyzing the options of restoration along Mill Creek include
the potential to increase instability along the reach and the existing utility easement along the left
bank of the channel. There is a potential to impact the utility easement by laying back the
channel to a stable slope depending on the final designed slope. In addition, when laying back
the slopes in just a short section of the channel there would be additional stress added to those
banks when the flow necks back down to the existing channel and could create a potential area of
erosion or scour. The channel has a large drainage area and storms or other events could
significantly impact the stability of the reach during the time it takes to stabilize the plantings.
This could lead to future maintenance issues and/or additional sedimentation into Mill Creek in
the interim.
Option 3: Enhancements Along Mill Creek

Option 3 includes enhancing the riparian buffer along Mill Creek. This option includes planting
of native bareroot tree and shrub species. The goal would be to plant a minimum 50-foot buffer
if possible; however, there is an existing utility easement that would not allow that width to the
south or along the left bank of Mill Creek. The minimum width of buffer along Mill Creek
would be 35 feet along the utility easement.

4.0 PROJECT COST ESTIMATES FOR UT TO MILL CREEK
Three cost estimates are provided below based on the three options that have been reviewed for
the potential mitigation site (Table 3). The first cost estimate provided is based on providing a
full restoration of the UT to Mill Creek by grading a new floodplain, installing a number of grade
control structures and steps to stabilize the channel, and plantings. In the table below this is
Option 1a.
Option 1b below is based on the proposed plan detailed in the previous sections of this document
which incorporate restoration, enhancement, and preservation of UT to Mill Creek. This option
attempts to strike a balance between the costs of full restoration and obtaining mitigation credits.
The Table below illustrates the cost estimate for Option 2.
The final option, Option 1c, is based on removing 141 linear feet of existing 24” pipe and
replacing it with a standard base ditch. This option does not propose mitigation credits for this
work. Instead, it avoids a potential issue with the existing pipe in the future by removing it prior
to access being removed or restricted.

submitted following issuance of RFC plans for the selected option.
2 Assumes work would be completed by the D-B contractor rather than an approved mitigation contractor.

Recommendations
Based on the above description of options regarding mitigation at the UT to Mill Creek and
Mill Creek at Phelps Drive, NCDOT has determined the best path forward as Option 1c which
is to remove the pipe on the UT to Mill Creek and stabilize the area and 2b which is removing
the pipe on Mill Creek and proceeding with the permitted plans for stabilizing the channel.
The decision to move in this direction was based on a number of factors such as cost of
construction when weighed against the potential mitigation credits, long term monitoring and
maintenance of the site, and utility encroachments. The overall benefit of doing full restoration
would not provide significant ecological uplift on either reach and could introduce instability
of either reach following construction.

Eric and Dave, 
Attached is a permit modification request for U‐2579DEF.  Let me know if you have any questions or need additional 
information to process. 

Dave and Kristi, 
Please use the meeting held January 10, 2019 to review the site as our preapplication meeting.  I’ve included an email 
chain that documents our discussion at the site as well as some additional mitigation questions.  As you will see in the 
application, we determined that onsite mitigation was not feasible. 

Michael Turchy, 
Please add to the permit application website for the WSNB.
