Dear Mr. Baker:
This letter addresses Section R-2518B of the 19E Widening Project that extends from SR
1421 (Windy Gap -Road) to SR 1336 (Jack's Creek Road). The North Carolina
Department of Transportation (NCDOT) proposes to widen US 19/US 19E from future I-
26 (existing 19-23) in Madison County to SR 1186 (US 19) near Micaville in Yancey
County. The total length of the project is approximately 21 miles. The length of the R-
2518B section is 6.9 miles. The project will upgrade the existing two and three-lane
principal arterial to a multi-lane facility with partial access control.

No major design changes have taken place since the original permit submittal however a
few minor revisions were introduced. Attached are the EEP confirmation letter, most
recent revisions to the permit drawings, roadway plan sheets, and a revised stormwater
management plan for R-2518B with detailed site descriptions to replace the original
corresponding pages. See below list of revisions to these plans.
• The impact summary sheet for R-2518B was revised to clarify impacts listed for Site
2A. reflect an error in site numbering. Site 2A in the original permit application
combined a stream impact site with a wetland site (wetland 2A). The stream impact
site is now listed as Site 2A (Permit Drawing Sheet 4) and the wetland is Site 22A
(Permit Drawing Sheet 23).
• There is expanded detail for the rock inlet sill at Site 8 on Permit Drawing Sheet 9.
• The approaches to the bridge over the Cane River have been shortened and the lateral
ditch detail above the Cane River has been revised on Permit Drawing Sheet 34.
• Sheet 2-J of the Roadway Plans has revised information for Detail DD.
• Sheet 17 of the Roadway Plans depicts rock plate fill being utilized in place of soil
based fill in the wetland (Wetland lA) located at station 160+60.
None of these changes will result in new impacts to jurisdictional resources. Please
refer to the original application and supplemental revisions for additional project
information.
IMPACTS TO WATERS OF THE U.S. - R-2518B
Wetlands
Permanent impacts: Wetland impacts total 0.23 acre, with 0.18 acre of impact to riverine
wetlands, and the remaining 0.05 acre of impact to non-riverine wetlands.
Temporary impacts: There will be no temporary fill in any of the wetland areas.
Surface Waters
Permanent impacts: Impacts to surface waters total 2,866 linear feet. There will be 70
square feet of impacts from bridge piers in the water at Price Creek (30 sq. ft.) and the
Cane River (40 Sq. ft.).
Temporary impacts: Impacts will be necessary for construction of the various box
culverts, pipe installations, and temporary causeways for the bridge replacements over the
Cane River and Price Creek. Temporary impacts associated with this project include 804
linear feet (0.16 acre) of temporary fill in surface waters.
The following table depicts all of the jurisdictional streams and wetlands impacted by the
final project design for Section R-2518B. Some streams were mapped by NCDOT in
preparation for the EA and were assigned names at that time.

MITIGATION OPTIONS
The NCDOT is committed to incorporating all reasonable and practicable design features
to avoid and minimize jurisdictional impacts, and to provide full compensatory mitigation
of all remaining, unavoidable jurisdictional impacts. Avoidance measures were taken
during the planning and NEPA compliance stages; minimization measures were
implemented during the design phase to include the examination of appropriate and
practicable steps to reduce adverse impacts from the project.
Avoidance on R-2518B
Permit Site 19: UT 18 to Bald Creek runs through an existing 1200 mm pipe (Sheet
20, Station 174+30) that will not be extended or replaced therefore, avoiding any new
impacts.
Minimization on R-2518B
Site specific minimization efforts that have been employed on R-2518B
include:
• Site 2A Sheet 4, Station 117+46): Preformed scour hole added at the end of the
pipe to attenuate and disperse concentrated flow before it enters the stream.
• Sheet 5 (Station 118+70 - 119+35): Natural rock energy dissipaters installed at
the pipe outlets to diffuse outlet velocities.
• Site 4 (Sheet 5, Station 120+10&61): Preformed scour holes at the end of the
pipes to attenuate and disperse concentrated flow into floodplain before entering
Bald Creek.
• Sheet 7, Station 126+52: Natural rock energy dissipater installed at the pipe outlet
to diffuse outlet velocities.
• Sheet 9, Station 135+24: Preformed scour hole at the end of the pipe to attenuate
and disperse concentrated flow into floodplain before entering Bald Creek.
• Site 9 Sheet 10, YS Station 10+28~: Natural rock energy dissipater installed at the
pipe outlet to diffuse outlet velocities.
• Sheet 11, Station 139+80): Natural rock energy dissipater installed at the pipe
outlet to diffuse outlet velocities.
• Sheet 12, Station 144+50): Natural rock energy dissipater installed at the pipe
outlet to diffuse outlet velocities.
• Sheet 15, Stations 155+00 & 155+59: Natural rock energy dissipaters installed at
pipe outlets to attenuate and disperse concentrated flow into floodplain before it
enters the stream.
• Site 14A (Sheet 16, Station 159+42): Natural rock energy dissipater installed at
the pipe outlet to diffuse outlet velocities.
• Sheet 20, Station 172+60): Natural rock energy dissipater installed at pipe outlet
to attenuate and disperse concentrated flow into floodplain before it enters the
stream.

• Sheet 20, Station 174+50: Preformed scour hole at the end of the pipe to attenuate
and disperse concentrated flow into floodplain before entering Bald Creek.
• Sheet 21, Stations 176+80 & 177+80: Permanent soil reinforcement mats were
installed at the pipe outlets to diffuse outlet velocities.
• Sheet 21, Stations 177+16: Preformed scour hole at the end of the pipe to
attenuate and disperse concentrated flow into floodplain before entering Bald
Creek
• Sheet 34, Stations 223+34 & 223+80: Permanent soil reinforcement mats were
installed at the pipe outlets to diffuse outlet velocities.
• Sheet 34, Stations 223+00 & 224+30: Hazardous spill basins will be installed to
collect and contain runoff from any accidental spills involving hazardous
materials.
Compensation for R-2518B
A field meeting to determine jurisdictional status was held on September 11, 2003 with
the USACE, DWQ, H.W. Lochner, Inc. and the DOT. During the field meeting the
stream at station 117+50 (site #2A) was determined biologically unimportant. It was
agreed that no mitigation will be required for impacts to this stream. Therefore, 131 linear
feet of impacts on this project will not require mitigation.
Compensatory Miti ation: Please refer to the original permit application and subsequent
revisions for NCDOT's mitigation strategy for the all three project Sections. Table 2
provides information about the on-site mitigation associated with each impact site within
R-2518B.

State Project: 34445.1.1 (R-2518B)
County: Yancey
Hydraulics Engrs: Bill Stephens (TGS Engineers), Galen Cail (NCDOT Hydraulics)
Project Description:
This project involves the widening of US 19 from East of the Madison-Yancey County
line to just East of the Cane River in Burnsville. The existing roadway is primarily atwo-
lane facility with shoulders. The proposed roadway will be a four lane facility with
shoulders and a 5.3m (17.5') raised grass median. The terrain along the project is rural,
mountainous with floodplain valleys.
Environmental Description:
This project is located in the French Broad River Basin. All of the streams are in the
Cane River Watershed with most being conveyed via tributaries of and including Bald
Creek. Most of the streams in the project limits are designated trout waters or tributaries
to trout waters and are classified as WS-II and CTr. The crossing at Lickskillet Branch is
a High Quality Water (HQW). There are no Outstanding Resource Waters (ORW) on the
project.
There are 31 streams along the project. Of the 31, there are 12 major stream crossings
including 9 box/ pipe culvert extensions and 3 bridges. One (1) of the major crossings
(Bald Creek) involves the replacement of an existing 4 barrel box culvert with a bridge.
The remaining 19 stream crossings involve pipe culverts. Total temporary and permanent
surface water impacts due to the project are 840 ft and 2866 ft, respectively. Specific site
impacts are provided in the permit impact summary. Specific hydraulic and BMP
information for each crossing is provided in the attached addendum. Rip rap required at
stream crossings will be placed on the stream banks only.
There are 2 wetlands impacted by the project. The total wetland impacts are 0.11 acres.
Specific site impacts are provided on the permit impact summary. Specific BMP
information at each wetland site is provided in the attached addendum.
Best Management Practices BMP):
Best Management Practices (BMP) are used along the project to control and mitigate
Stormwater pollution and erosion conveyed to streams, to improve fish passage, to
provide outfall stability and to promote stable stream banks and streambeds.

The primary BMP on this project is the grassed swale. The grassed swale criteria is met
using both standard roadway and/or special drainage ditches. Where possible, drainage
systems will outlet away from streams into grassed swales to allow opportunity for
infiltration. Grassed swales remove suspended solids, metals and nutrients through
sedimentaion, vegetative filtration, infiltration and biological uptake. Additional
consideration was given where stabilization was a concern and a ditch liner was needed.
The use of permanent soil reinforcement mat (PSRM) was considered in-lieu of rip rap.
The PSRM allows vegetation to grow and thus allows Swale treatment (infiltration). The
use of PSRM versus rip rap was dependent on overall ditch stability (shear stresses) with
consideration to stormwater discharge, velocity, slope and R/W and/or site restrictions.
Other BMP's utilized on the project are preformed scour holes (PSH), hazardous spill
basins (HSB), low flow rock inlet sills, outlet rip rap pads and burying of culvert
extensions (where practical).
The PSH's are used to dissipate energy and attenuate and diffuse flow at outlets. By
inducing diffuse flow, PSH's promote runoff infiltration and reduce downgrade erosion.
The HSB's are located at the outfalls on each side of the Cane River. They are used to
provide resource protection from potential spills along the road facility. Runoff from the
Cane River bridge deck will be directed to the basins along with drainage within the local
roadway facility.
The low flow rock inlet sills are used at some culvert inlets, to improve low flow fish
passage and to improve sediment transport.
The outlet rip rap pads are proposed at existing outlets to improve outlet stability and
reduce erosion.
There is also on-site stream mitigation proposed throughout the project along Bald Creek
and a Tributary to the Cane River. The mitigation will provide both stream restoration
and enhancement. See mitigation plans for specific site information and details.
