SR 1129 (Laurel Creek Road)
Watauga County, North Carolina
Project Number: 110.095081 (DWQ Permit Fee: $475)
Dear Mr. Thomas:
The NC Department of Transportation is scheduled to grade, drain, base and pave a portion of SR
1129, Laurel Creek Road in Watauga County. Due to right-of--way limitations, we will have a
gapped section running from stations 29+15-35+65. The project will end at station 60+00. Total
project length is approximately 1 mile. The roadway will be widened from 16 feet to 20 feet with
impervious surface area increasing by 0.5 acres. This project will require the replacement of
seven wet pipes as shown below:

* Due to slope, these pipes will likely remain perched after replacement. If so, a riprap energy
dissipater pad will be placed in the stream channel under the pipe outlets.
The replacement of the existing wet pipes will require temporary dewatering. An impervious
sandbag dike will be constructed approximately 20 feet upstream of the existing culverts to create
a small pool. Clean water will temporarily be pumped around the construction areas and will be
discharged downstream of the construction areas. Any dirty water located inside of the
construction areas will be pumped into a silt bag if necessary. Total dewatered azea for all wet
pipes will be approximately 0.033 acres. Once the new pipes are in place, the impervious dikes
will be removed and preconstruction streambed elevations will be restored.
The wet pipes in question carry different unnamed tributaries to Laurel Creek (Class: C, Trout).
This project was reviewed for the presence of threatened and endangered species on December 5,
2006. This project will have no effect on any federally listed endangered plant or animal species.
The State Historic Preservation Office has reviewed this project and did not request any survey
work.
The project impacts aze minor in nature and should not remove or degrade existing water quality
uses. Pipe sizes used will be the minimum necessary to create a safe roadway. By utilizing the
erosion control measures outlined in the attachments to this application, downstream water
quality standards will be protected. All appropriate BMPs will be used during construction.
Attached is a Preconstruction Notification Form, plan sheets with proposed erosion control
measures, a marked county map, a marked topography map and photographs.
By copy of this letter, it is requested that Mr. Ron Linville, Mountain Region Coordinator, with
the North Carolina Wildlife Resources Commission comment directly to you concerning the 404
Nationwide Permit application with a copy sent to me.
By copy of this letter, I am forwarding seven (7) copies of this application package to John
Hennessy, NCDENR, Division of Water Quality, 401/Wetlands Unit, for his review. It is
requested that any comments related to the 401 certification be forwarded duectly to me with a
copy sent to the US Army Corps of Engineers.
We would like to begin construction as soon as possible. If further information is required, please
let me know. Your eazly review and consideration will be appreciated.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
By utilizin¢ the erosion control measures as shown in the attached drawings adverse impacts to
streams in the area will be minimized. Since this is an existing roadway the stream impacts
cannot be avoided. However, the replacement pipe lengths will be the minimum needed to
safely construct the paved roadway. All appropriate BMPs will be used during construction
Page 7 of 12

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr state.nc us/ncwetlands/strm~ide html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
