Subject: Application for Section 404 General Permit 31 and Section 401 Water Quality
Certification for the proposed replacement of Bridge No. 134 over Stony Fork
Creek on NC 151 in Buncombe County, Federal Aid Project No. BRSTP-151(10);
Division 13; TIP No. B-4034
$570.00 debit WBS 3340
Dear Sir:
The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge No. 134
over Stony Fork Creek on NC 151. There will be 439 feet of permanent surface water impacts. This
project has an unusually complex design due to steep topography. Please consider the following as a
further explanation of impacts:
1) Stream relocation: The UT to Stony Fork Creek is being relocated from the fill slopes on
the new road. It may appear that it is the detour route that pushes it over when it is actually
the fill. Natural stream design was investigated for the stream location. However, due to
steep topography in this area, natural stream design is not possible. (Permit drawing 5 of 14)
2) Existing pipe location: Channel work in this area will impact the bottom of the stream and
therefore not qualify as bank stabilization. (Permit drawing 6 of 14)
3) Existing bridge location: Due to hydraulic modeling and the bend just downstream of the
bridge, there is evidence to indicate that the stream will have a tendency to scour over time,
and compromise the bridge abutment. Because of this, the existing abutment will remain in
place to stabilize the bank. To create a larger hydraulic opening, the abutment will be cut so
that it is one foot above the normal water mark and the bank will be rip-rap up to the
abutment. There is a cross section which illustrates the areas to be excavated in order to
provide a larger hydraulic opening. (Permit drawing 14 of 14)

4) As a minimization measure, Corrugated Steel Pipe Arches (CSPA) will be installed where
the private drive and new road crosses the relocated UT to Stony Fork Creek. CSPA pipes
decrease the amount of needed fill, reduce fill slopes and reduce over-all length of pipes.

Please see enclosed copies of the Pre-Construction Notification (PCN), EEP acceptance letter,
Stormwater Management Plan, permit drawings and design plans. The Categorical Exclusion (CE)
was completed in August 2007 and the Right-of-Way Consultation was completed in October 2008.
Documents were distributed shortly thereafter. Additional copies are available upon request.
This project calls for a letting date of February 16, 2011 and a review date of December 29, 2010.
However, the project may be advanced as funding becomes available.
Comments from the North Carolina Wildlife Resources Commission (NCWRC) will be required
prior to authorization by the Corps of Engineers. By copy of this letter and attachments, NCDOT
hereby requests NCWRC review. NCDOT requests that NCWRC forward their comments to the
Corps of Engineers and the NCDOT within 30 calendar days of receipt of this application.
A copy of this permit application will be posted on the NCDOT Website at:

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed bridge is 44 feet longer than the existing bridge and the hydraulic connectivity will be increased by
excavating material beneath the old bridge. It will be in the same location as the existing structure with a temporary on-
site detour using a temporary bridge; an off site detour is not practical. The "do-nothing" alternative was not considered
due to the resulting elimination of the use of NC 151 and closing or removing the bridge. A moratorium for in-stream work
to protect trout is in effect from January 1 to April 15 in addition to Design Standards in Sensitive Waters.
1b . Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Corrogated Steel Pipe Arches will be installed at the private drive and new road crossing for the relocated UT to Stony
Fork Creek. These pipes (CSPA) reduce the amount of fill and the overall length of pipes. Impacts will also be minimized
by constructing a spanning structure and surficial bridge runoff will not be directed into Stony Fork Creek via deck drains

Dear Mr. Baker:
Subject: EEP Mitigation Acceptance Letter:
B-4034, Replace Bridge Number 134 over Stony Fork Creek on NC 151,
Buncombe County; French Broad River Basin (Cataloging Unit 06010105);
Southern Mountains (SM) Eco-Region
The purpose of this letter is to notify you that the Ecosystem Enhancement Program (EEP) will
provide the compensatory stream mitigation for the unavoidable impact associated with the above
referenced project. As indicated in the NCDOT's mitigation request dated May 4, 2009, stream
mitigation from EEP is required for 439 feet of cold stream impact.
Mitigation associated with this project will be provided in accordance with Section X of -
Amendment No. 2 to the Memorandum of Agreement between the N. C. Department of Environment and
Natural Resources, the N. C. Department of Transportation, and the U. S. Army Corps of Engineers fully
executed on March 8, 2007 (Tri-Party MOA). EEP commits to implement sufficient stream mitigation up
to 878 cold stream credits to offset the impacts associated with this project -by the end of the MOA year in
which this project is permitted. If the above referenced impact amounts are revised, then this mitigation
acceptance letter will no longer be valid and a new mitigation acceptance letter will be required from
EEP.
If you have any questions or need additional information, please contact Ms. Beth Harmon at
919-715-1929.

Project: 33401.1.1
TIP No. B-4034
Buncombe County
5/19/2009
Hydraulics Project Manager: Max Price, P.E. (Wetherill Engineering),
Marshal Clawson, P.E. (NCDOT Hydraulics Unit)
ROADWAY DESCRIPTION to
The project B-4034 involves the replacement of Bridge No. 134 on NC151 over
Stony Fork Creek in Buncombe County. The existing bridge is a 1 @ 41.3' reinforced
concrete thru girder with concrete abutments, it is 20.3 feet wide. The proposed
replacement structure is a 1@ 85' box beam bridge with spill through abutments, and will
be 33.5 feet wide. The roadway grade will be raised approximately 1.8 feet in the vicinity
of the bridge in order to maintain the same low steel elevation as the existing structure.
The existing roadway approach section is 18 feet of pavement with grass shoulders that
are approximately 2 feet wide. The proposed roadway approaches to the bridge will
consist of 2- 12 foot lanes with 8 foot shoulders. (4 foot paved, 4 foot grassed). The
intersection of SR-1102 (Davis Chapel Church Road) on the south end of the bridge, and
a private drive on the north end of the bridge require relocating to improve sight
distances. A temporary one lane detour will be constructed on the west side of NC 150. A
temporary detour bridge 85 feet in length will be constructed approximately 40 feet
downstream of the existing bridge. The project drainage system will consist of cross
pipes, grated inlets with associated pipe systems, drive pipes, roadway swales, and lateral
storm water swales.
ENVIRONMENTAL DESCRIPTION
The project is located in the French Broad River Basin. The NCDWQ surface
water classification for Stony Fork Creek is C (Aquatic Life and Secondary Recreation)
and Trout Waters. There are also four unnamed tributaries and a pond located in the
project area, and they receive the same classification as Stony Fork Creek. No
Outstanding Resource Waters, Water Supply Watersheds or watershed Critical Areas
occur within one mile of the project area. There will be no impacts to jurisdictional
wetland as a result of this project. There will be +/- 0.05 acres permanent surface water
impacts, and 459 feet of permanent channel impacts.
BEST MANAGEMENT PRACTICES AND MAJOR STRUCTURES
The primary goal of Best Management Practices (BMPs) is to prevent degradation
of the states surface waters by the location, construction and operation of the highway
system. The BMPs are activities, practices and procedures taken to prevent or reduce
stormwater pollution. The BMPs and measures that will be used on this project to reduce
stormwater impacts are rip rap energy dissipater pads to diffuse velocities at pipe outlets.
No direct discharge from the bridge deck into Stony Creek. Storm drainage was designed
to discharge runoff from paved surfaces in such a way as to maximize the grass swale or
natural vegetated swale flow length before discharging into stream. The temporary detour
was located on the west side on NC 150 in order to avoid impacts to the wetland located
on the east side on NC 150. A one lane detour with signals was utilized in order to
minimize the foot print of the temporary detour construction. A single span permanent
bridge structure was utilized in order to avoid placing bridge bents in the stream or at the
water edge in order to avoid local scour.
