Subject: Application for Section 404 Nationwide Permits 13, 14, 33 and Section 401 Permit
for widening of NC 16 Southeast of SR 1158 (Claudemash Road) to southeast of NC 88
in Ashe County, Federal Aid Project Number STP 16 (1), State Project No. 8.1710901,
Division 11, T.I.P No. R-2100B.
Debit $570.00 from WBS No. 34369.1.1.
The North Carolina Department of Transportation (NCDOT) proposes to improve a 2.4 mile
section of NC 16 in Ashe County by widening the existing roadway to a 24-foot pavement,
installation of guardrail at selected locations, construction of a new bridge over Bear Creek, and
minor horizontal and vertical alignment changes to improve sight distance. There will be 732
feet of permanent surface water impacts and 0.03 acres of temporary surface water impacts at
Sites i - 18 as well as less than 0.01 acre of wetland impact at Site 1. These impacts occur as a
result of pipe installations and stabilizations, a stream relocation, and replacement of a culvert
with a bridge.
Please see the enclosed copies of the Pre-Construction Notification (PCN), Ecosystem
Enhancement Program (EEP) acceptance letter, meeting minutes from 413 and 4C, permit
drawings, and design plans for the above-referenced project. Also included are the Stormwater
Plan, application, and permit. The Environmental Assessment (EA) was completed for this
project in June 1990, the Finding of No Significant Impact (FONSI) was completed in November
1995, and.a Project Environmental Consultation update was completed in November 2007 and
all were distributed shortly thereafter. Additional copies are available upon request.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Use of 2:1 max side slopes at wetland and stream locations, retaining walls along stream/river side shoulder, preformed
scour holes, where practical, Permanent Soil Reinforcement Matting in lieu of rip rap in some ditches, where possible,
NCDOT is spanning Bear Creek, decreasing shoulder width in the area where the Virginia spiraea is located and utilizing
a horizontal alignment design exception that enables a reduction in cut/fills/earthwork. Also, Division 11 eliminated the
temporary roadway detour at the bridge construction site. .

With the exception of not building the project, there are no means of avoiding impacts to waters of the State. NCDOT will
minimize impacts to the streams through the use of Best Management Practices.

General
• Retaining walls have been added along the project to keep the construction footprint
to a minimum. Paved ditches will be behind the retaining walls on the mountain side.
• Shoulder berm gutter (SBG) will be along the retaining walls on the stream side.
• Jon Scarce is going to give Galen Cail a list of all box structures on the project to see
if they can be retained or should be removed
• At jurisdictional streams, rip rap should be placed on banks only. Note on plans.
• At system outlets, investigate using deeper drainage structures to flat outlet pipes to
reduce velocities. Use preformed scour holes (PSH) at outlets, where practical.
• Use roadside ditches, to extent practical, to get stormwater treatment.

The following is a brief summary of the discussions on the project:
General Introduction was initiated by Marshall Clawson. Introductions were made by all
in attendance.
General
• The retaining walls were left off of the permit drawings and need to be shown on
the final permit drawings.
• Station and location of all direct discharges need to be added to the stormwater
management plan and a reason provided as to why direct discharge could not be
avoided.
• Account for impacts where ditch/JS channel work is required to tie into other JS.
le impacts associated with tie ins to Bear Creek and South Fork New River.
Sheet 4
Retaining wall located from -L 1- Station 252+50 +/- Lt. to 256+00 +/- Lt.
o The wall is going to be built from the roadway side and will not impact to
the stream.
Cross pipes located at -L1- Station 258+05 +/- (Permit Site 1) and 260+30 +/-
(Permit Site 2)
o For onsite mitigation, stream restoration will be performed on the larger
tributary just downstream of these crossings. Part of that plan may involve
utilizing a step pool system for these two smaller tributaries. This would
be done from the proposed'pipe outlets to the relocated larger downstream
tributary.
o The stream impact currently shown is only to the limits of the proposed
pipe ends. The current wetland impacts are shown as 0.01 and 0.00
respectively. Impacts to both, could increase depending on the stream
restoration final design.
o The need for replacing the pipes was questioned. It was stated that the
pipes have to be replaced due to their current condition and they are being
replaced with a larger pipe to have the invert buried 20% of the pipe size
up to one foot.
Stream Restoration
o A priority one restoration could not be achieved due to slope constraints.
The design presented was a preliminary design, and changes would be
forthcoming after a planned onsite meeting.
Sheet 5
• Cross pipe located at-Ll- Station 266+77 +/- (Permit Site 3)
o There is stream impact at the outlet. Outlet Channel Detail width to be
revisited.
• Cross pipe located at -L I- Station 272+00 +/- (Permit Site 4)
o There are stream impacts at the inlet and outlet.
• Legend symbology should read "Denotes Impact to Surface Waters"
• Due to a possible seep and wall weep holes, a TBDI will be added somewhere
near 270+00 RT.
Sheet 6
Cross pipe located at -L1- Station 277+45 +/- (Permit Site 5)
o This site will be removed since there are not any impacts. Outlet channel
detail width to be revisited.
• Lateral 5 foot base ditch from Station 283+42 +/- to Station 284+35 +/- (Permit
Site 6)
o Ditch is on a 10% grade and warrants the need for Rip Rap.
• Cross pipe located at Station 286+50 +/- (Permit Site 7)
o There are stream impacts at the inlet and outlet.
Sheet 7
• Cross pipe located at -L 1- Station 296+88 +/-(Permit Site 8)
o There are stream impacts at the outlet. Existing stream is rock, so the rip
will be removed which will reduce amount of impacts shown on the
permit drawings.
Sheet 8
Spirea at -L1- Station 304+00 +/- (Permit Site 8)
o No impacts were found on this sheet at the time of the permit drawings,
including impacts to the spirea. This area has been looked at since the
original permit drawings were completed and impacts due to the rip rap
pad outlets out the South Fork of the New River will need to be calculated.
This sheet was not included in the original permit package, but it will be
added.
Sheet 9
Cross pipe located at -L 1- Station 318+04 +/- (Permit Site 9)
o There are stream impacts at the inlet and outlet. Request was made to
have rip rap added in outlet stream channel to reduce erosion potential.
Add a note in channel detail about flaring the outlet channel width from
the pipe width down to the existing channel width.
Cross pipe located at -L1- Station 322+20 +/- (Permit Site 10)
o There are stream impacts at the inlet and outlet. Request was made to
have rip rap added in outlet stream channel to reduce erosion potential.
.Sheet 10
• Cross pipe located at -L1- Station 330+50 +/- (Permit Site 11)
o There are stream impacts at the inlet. No stream or impacts at outlet.
Sheet 11
Cross pipe located at -L I- Station 344+97 +/- (Permit Site 12)
o This site has been added since the 4B meeting. There are stream impacts
at the inlet and outlet. Outlet Channel Detail width to be revisited.
Sheet 12
• Bridge located at-L1- Station 364+50 +/- (Permit Site 13)
o Existing structure will be removed. A Single span, 80 foot long bridge
will be put back in its place. The stream banks will be laid back and rip
rapped. It is still unclear whether an onsite or offsite detour will be used at
this location.
o Look at removing rip rap along the 10 foot berms near top of banks to
allow for better wildlife passage.
o The detour structure is currently a 143"x86" CSPA. It was questioned why
a temporary bridge couldn't be used instead. Per Structures, the CSPA is
preferred from a con.structability, construction life, safety and cost
perspective. A conventional temporary detour bridge could not be
constructed on curved (0.06 super) alignment. The curve would have lobe
placed on a wider, tangent bridge. Construction of bridge could increase
construction time a minimum of one month. Also, the potential icing of a
bridge on this superelevation is more a concern than the road at the
superelevation.
0
Sheet 2A
• Temp Crossing located at -L 1- Station 15+65 -DET-+/- (permit Site 14)
o The temporary detour structure will cause temporary impacts to the
stream. As stated from sheet 12, an offsite detour may be used in the place
of this temporary structure.
Meeting Adjourned.

TIP Project: R-2100B
Ashe County, North Carolina
Hydraulics Project Engineer: Jonathan K. Scarce, PE
NCDOT Hydraulics Project Engineer: Marshall W. Clawson, PE
Proiect Description:
This project, designated as the "B" section, will be improvements to NC 16 from
Southeast of SR 1158 to Southeast of NC 88. The project is a proposed upgrade of the
existing two lane road. The overall project is 2.4 miles in length.
Environmental Description
This project is located in the New River Basin, for which no buffer regulations have been
implemented. Bear Creek will be crossed once by the proposed action. The South Fork
New River and an unnamed tributary to the South Fork New River parallel portions of
the project. Bear Creek is listed on the NCDENR classifications list as a Class WS-IV
and Class Tr. The South Fork New River and the unnamed tributary to the South Fork
New River are listed as a Class WS-IV and HQW. Class WS-IV means the stream is a
"Water Supply IV" which stands for highly developed water supply. Class Tr means the
stream is trout water. HQW means the stream is high quality waters. Neither Water
Supplies (WS-I or WS-II) nor Outstanding Resource Waters (ORW) occur within 1.0
miles of the project. Bear Creek, the South Fork New River nor the unnamed tributary to
the South Fork New River were found on the 303(d) list for impaired streams. Wetlands
are located on the southeast quadrant at the beginning of the project along the unnamed
tributary to the South Fork of the New River. Less than 0.1 acres of wetland are impacted
at this site.
Roadway Description:
The proposed roadway cross section is a 2-lane facility, consisting of 12 foot travel lanes,
2 foot full depth paved shoulders, 6 foot grass shoulders (9 foot with guardrail). The
project drainage system will consist mainly of ditches and cross pipes. Storm systems
will also be used in order to pick up roadside ditch drainage as well as drainage at the
retaining walls along the project and discharge into a preformed scour hole, ditch or
stream.
Beim drainage outlets will be used in order to pick up off site drainage at the top of the
high cut slopes. The berm drainage outlets will discharge into a 2GI along the bottom of
the cut slope. The 2GI will connect into a storm system and outlet into a ditch.
Page 1 of 3
R-210013 Storuwater Management Plan
1 1 /25/2008
Shoulder berm gutter will be utilized in areas of high fi ll and/or excessive runoff as well
as along the top of retaining walls. In these instances, the runoff will be collected in a
2GI and discharged into a preformed scour hole, ditch or stream.
Best Management Practices and Major Structures:
• Major Structure
A single span bridge will be placed from -LI - Station 364+10.00 to -L1-
Station 364+90.00 in order to replace the existing cast in place concrete
slab bridge with vertical abutments. The proposed bridge will have spill
tlnru abutments. Neither the existing nor the proposed bridge has bents in
the channel. The bridge is also designed so that no deck drains will be
used in order to avoid any direct discharges into Bear Creek. All deck
drainage will be picked up in a stone system and discharge at the toe of
slope near the bridge.
• Retaining Walls
Retaining walls were used in order to keep the fill slope from encroaching
into the unnamed Tributary to South Fork and the South Fork New River,
as well as to decrease the amount of cut needed along the mountahnside
paralleling the South Fork New River.
• Roadside Ditches
The majority of roadside ditches on this project were unable to obtain a
3:1 slope or flatter due to the physical constraints of the mountainside.
Most ditches on this project were lined with rip rap or permanent soil
reinforcement matting in order to control erosion.
• Rip Rap Pads & Preformed Scour Holes
Rip Rap pads and Preformed Scour Holes were used in order to dissipate
energy and reduce velocities at pipe outlets. These structures are located
throughout the project.
• Cross Pipes
In order to allow for fish passage, cross pipes will be buried a minimum of
20% of the diameter of the proposed pipe size, up to and including 48"
diameter. Pipes greater than 48" will be buried 1 foot.
• Unavoidable Direct Discharge Locations
Station 274+75 LT - Proposed system is replacing an existing system that
currently discharges directly into the Tributary to South Fork of New
River. The proposed retaining wall on the left side keeps the fill from
encroaching on the Tributary and there is a mountainside on the right;
Page 2 of 3

R-2100B Stormwater Manaeement Plan
11/25/2008
therefore, there is no room left to avoid direct discharge. Grassed lined
ditches are used at the inlet for treatment. The last box in the system has
also been designed as a drop box to minimize outlet pipe velocities into
the receiving stream.
Station 280+15 LT & 291+00 LT - Proposed systems are replacing
existing systems that currently discharge directly into the Tributary to
the South Fork of New River. The proposed retaining wall on the left side
keeps the fill from encroaching on the Tributary and there is a
mountainside on the right; therefore, there is no room left to avoid direct
discharge. Permanent soil reinforcement matting has been placed on the
incoming ditches to allow for treatment in a grass lined ditches.
Station 293+75 LT - Proposed system is replacing an existing system that
cwTently discharges directly into the Tributary to the South Fork of New
River. The proposed retaining wall on the left side keeps the fill from
encroaching on the Tributary and there is a mountainside on the right;
therefore, there is no room left to avoid direct discharge. Permanent soil
reinforcement matting has been placed on the incoming ditch to allow for
treatment in a grass lined ditch. The last box in the system has also been
designed as a drop box to minimize outlet pipe velocities into the
receiving streatn.
Stations 299+95, 302+55, 306+50, 311+05, 315+00 LT - Proposed
systems are replacing existing systems at or near the same locations where
they currently directly discharge into the South Fork of New River. The
proposed retaining wall on the left side keeps the fill from encroaching on
the South Fork of the New River and there is a mountainside on the right;
therefore, there is no room left to avoid direct discharge. Pipes are
outletting near the shoulder of the road, and Class II Rip Rap with Filter
Fabric has been placed along the stream banks to dissipate outlet velocities
from the pipes and to protect the stream banks from erosion.
