Subject: Nationwide 14 Permit Application for the Installation of a culvert on SR 2145 (Old Stage
Coach Trail) on Horsepen Creek, Guilford County, North Carolina, WBS Element No. 44449
Dear Mr. Bailey and Mr. Wrenn:
The North Carolina Department of Transportation (NCDOT) is proposing to install a culvert on SR 2145
(Old Stage Coach Trail) where previously there was a bridge. The purpose of the project is to restore a
former roadway connection along a roadway network with a new, h�iple bairel box culvert (2 at 12'X8'
RCBC). No detour will be necessaiy to convey traffic during conshuction as the roadway isn't currently in
use. The project will also include some minor approach work on the existing roadway which inchides
shifting the roadway alignment to the south to insure that tl�e conservation ease�nent for the immediately
adjacent stream restoration site will not be disturbed.
The North Carolina Natural Aeritage Database was checked for records of threatened and endangered
species. A survey for the Sinal] Whorled pogonia species and habitat was conducted in May 2016 and
while there was habitat present, no specimens were found. Therefore a"No Effect with HabitaY' biological
conclusion was rendered. Bald eagle is protected in every county in North Carolina under the Bald and
Golden Eagle Protection Act. No suitable feeding/water source is located within one mile of the project
study area to support Bald eagle habitat. Further, Mr. Gary Jordan (USFWS) recently released the
ProgrammaHc Conference Opinion (PCO) for the recently listed Northern Long Eared Bat (NLEB). This
opinion, states in part, that "... it is lhe Se�vice's confere�tce opinion £hat NCDOT activities in eastern North
Carolina (Divisions 1-8), as proposed, are �aot likely to jeopardize the cmitinued existeisce ofthe NLEB. "
This project was reviewed by,NCDOT's Human Environment Unit in 2015 for potential affects to
histoiica] architecture and archaeology. It was determined there would be no eligible architectural or
archaeological resources present within the project study area.
The project study area is comprised of a mix of hardwood forest, grassed open areas and existing roadway
surface. The immediate surrounding area is industrial in nature including Honda Aircraft Company,
HAECO Americas, the Piedmont Triad International Airport, Interstate 73 and a sewer line easement.
NCDOT best management practices (BMPs) wi1] be used to minimize and control sedimentation and
erosion. The construction foreman will review tl�e BMPs daily to ensure erosion and sedimentation is
being effectively controlled. If the foreman determines the devices are not functioning as intended, they
will be replaced inunediately with better devices.

Horsepen Creek (DWR Class: WS-II; NSW) is shown on the USGS topographic map as a perennial stream.
The channel is well defined with a substrate primarily composed of sand and silt, and is approximately 15-
20 feet in width. From the project site, Horsepen Creek flows east to its confluence with Lake Brandt
which flows into Lake Townsend. Reedy Fork flows from Lake Townsend to its confluence with the Haw
River. The Haw River meets the definition of a Traditiona] Navigable Water. For these reasons, we
believe Horsepen Creek is a Relatively Peimanent Water and is under the jurisdiction of the U.S. Army
Coips of Engineers. In order to construct the project, it will be necessary to impact waters of the United
States in the Cape Fear River Basin (HUC 03030002). Streamside riparian zones within the study area are
protected under provisions of the Jordan Lake Water Supply Watershed Buffer Rules administered by the
NCDWR. The attempt has been made to avoid and minimize impacts to sheams and wetlands to the
greatest extent practicable in choosing a preferred alternarive. Specifically, NCDOT is requesting to install
a new, hiple barrel, reinforced concrete box culvert. The impacts are listed in the table below:

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project study area is mostly comprised of forested land, however, the immediate surrounding area is industrial in
nature include Honda Aircraft Company, HAECO Americas, the Piedmont Triad International Airport and Interstate 73.
There are no other jurisdictional features in the project area, besides Horsepen Creek.
3b. List the total estimated acreage of all existing wetlands on the property:
There are no wetlands within the project study area.
3c. List the total estimated linear feet of aIl existing streams (intermittent and perenniai) on the property:
� 100 LF of stream within the project boundaries
3d. Explain the purpose of the proposed project:
To restore a former roadway connection along a roadway network. Employment increases in the area since 2007 have
resulted in an increase from 14,634 trips per day to 27,570 trips per day - almost double the amount of trips.
3e. Describe the overall proJect in detail, including the type of equipment to be used:
There is currently no traffc on the road as it stubs out, so a detour will not be necessary. Erosion and sedimentation control
measures will be installed. Water will be diverted around the construction area. The original structure was nearing the end of its
service life and was removed approximately 10 years ago. NCDOT proposes to now replace the structure with three, 12 ft. X 8
ft. box culverts just south of the original structure location. The new RCBC proposes 2 foot silis in the outer, high flow barrels
and a 1 foot sill in the central, low flow barrel. During construction, impervious dikes wiil be installed up and downstream of the
bridge and the stream will be placed in a 36" temporary pipe while the cuivert is installed. Once completed, stream flow will be
placed into low flow barrel and the area stabilized (see attached sequencing plan). Equipment to be used includes a track hoe,
dump truck, paving equipment, pumps and various hand tools.

D. Impact Justification and Mitigation
7. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed project is to restore an east-west connection 6etween Ballinger Road and Chimney Rock Road along the
existing Stage Coach Trail . Roadway approach work is minimized as much as is practical to reduce the overali project
footprint. Impacts to the associated protected riparian buffers have also been reduced by promoting sheet flow as well as
providing grass shoulders to promote infiitration. Bank stabilization wiil be minimized to those areas where deemed
necessary.
Providing a connection between Service Center Drive and Chimney Rock Road over Horsepen Creek to address purpose and
need was considered. New location alternatives were considered but dismissed from further study as they would impact a
restored stream and wetland mitigation site, introduce impacts to previously undisturbed streams, buffers, and uplands. The
costs would be substantially higher to construct a new location connection. Providing a connection that utilized the former
bridge location on Stage Coach Trail over Horsepen Creek was analyzed and determined to be the alternative that best
addressed purpose and need while avoiding and minimizing impacts to jurisdictional areas. Based on further review to avoid
and minimize impacts, the Iocation of the proposed crossing over Horsepen Creek on Stage Coach Trail was shifted slightly to
the south away from the mitigation site(conservation easement.
A bridge versus culvert was studied to determine the type of crossing structure to be constructed on Stage Coach Trail over
Horsepen Creek. A bridge spanning structure was compared to a three@12 feet by S feet reinforced concrete box culvert
(RCBC) as the proposed replacement structure to cross Horsepen Creek. The results of this comparison show that a bridge
structure would avoid stream and buffer im acts to Horse en Creek. The former brid e consisted of a 21 feet 10 inch sin le
Page 6 of 11
PCN Form — Version 1.3 December 10, 2008 Version

span bridge with concrete abutments and has similar hydraulic characteristics including backwater impacts and outlet
velocities when compared to a culvert. In analyzing a bridge structure, a 180-foot bridge was reviewed and resulted in a 100
YR water surtace increase of 1.75 feet. Increasing the bridge length even more did not result in reduction in the 100 YR water
surface below the 1.00-foot threshold. This is likely due to the significant overtopping of Old Stage Coach Road projected in
the 100 YR event. If a bridge is utilized there must be at least four feet of clearance under the bridge to allow access for
maintenance workers at the abutment. In areas where bridges are recommended this requires NCDOT to raise the roadway
grade, which increases the backwater/road overtopping impacts, as well as increases the roadway fill slope footprint.
The culvert structure meets the hydrological and FEMA requirements of the drainage area without significantly increasing the
100 YR water surface elevation for the FEMA Flood study for Horsepen Creek. A box culvert structure does not require
raising the roadway grade to the extent a bridge structure requires. A CLOMR (Conditional Letter of Map Revision) and
LOMR (Letter Of Map Revision) will need to be reviewed and approved by FEMA for this crossing. FEMA requires that the
100 YR water surface not be increased by more than 1.00 feet from the established (mapped) water surface elevation. As
stated earlier, a bridge raises the water surface 1.75 feet, therefore using a bridge structure increases the probability of not
gaining approval of the CLOMR coordinated through FEMA.
The basin drainage area and estimated discharges are compatible with a culvert structure and are often best suited to
minimize raising the roadway grade. Where site conditions allow culverts are typically preferred due to longer service life and
reduced maintenance versus a bridge. Both upstream and downstream of the proposed crossing are existing three @ 12 feet
by 8 feet RCBC's which are located approximately 1100 feet and 2000 feet, respectively, from the Old Stage Coach Road
crossing. Any proposed bridge structure would be considered fatally flawed because it could not be built long enough to
resolve the FEMA backwater issue.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Erosion and sedimentation BMPs will be installed prior to construction. Water will be diverted around the work area to prevent
sedimentation of downstream aquatic resources. Impacts will be minimized by strict enforcement of Best Management
Practices for the protection of surface waters, restrictions against the staging of equipment in or adjacent to waters of the US
and coordination (including a pre-construction meeting) with the Division Environmental Supervisor.

Wetland Rules (15A NCAC 2H .1300), DWQ Surtace Water or Wetland Standards, ❑ Yes � No
or Riparian Buffer Rules (15A NCAC 2B .0200)?
2b. Is this an after-the-fact permit application? ❑ Yes � No
2c. If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s):
3. Cumulative Impacts (DWQ Requirement)
3a. Will this project (based on past and reasonably anticipated future impacts) result in � Yes � No
additional development, which could impact nearby downstream water quality?
3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy. If you answered "no," provide a short narrative description.
Per the NC DWQ April 10, 2004 Version 2.1 Cumulative Impacts policy, small scale public transportation projects — such
as widening projects, bridge replacements and intersection improvements — have a"low potential for cumulative impact
since littie (if any) new impervious surface is added and the projects are usually in already developed Iocales:' This
proposed project is within a somewhat developed landscape (i.e. existing businesses and industrial buildings in the
vicinity), this is not a road on a new location (i.e. there is an existing road and there used to be a bridge structure and
thus, the area already contains impervious surfaces) and the project drains to Horsepen Creek, which is Class WS-III;
NSW (i.e. not HWQ or ORW). We anticipate the NC DWR will advise us if a qualitative or quantitative analysis is needed.
4. Sewage Disposal (DWQ Requirement)
4a. Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility.
It is not anticipated that this project will generate any wastewater as it is a roadway project.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or � Yes � No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
impacts? � Yes ❑ No
� Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
North Carolina Natural Heritage Database and onsite investigation. On May 9'h, Jeff Hemphill of NES reviewed the
project site for the Small whorled pogonia and found no specimens but did determine that there is habitat present.
Therefore, the biological conclusion is No Effect with Habitat.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat? ❑ Yes � No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
This project takes place in Guilford County which is not near any coastal or tidal habitat that would support EFH (i.e. salt
marshes, oyster reefs, etc.).
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation � yes � No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
This project was submitted to the North Carolina Department of Transportation's Human Environment Unit for review in
June 2015. It was determined that no survey was required for historic architecture or for archaeological resources (see
attached letters).
8. Flood Zone Designation (Corps Requirement)
Sa. Will this project occur in a FEMA-designated 100-year floodplain? � Yes ❑ No
Sb. If yes, explain how project meets FEMA requirements: MOA
8c. What source(s) did you use to make the floodplain determination? North Carolina Floodplain Mapping Program
