SR 1147 -East Alarka Road
Swain County
State Project No. 140.087014 (DWQ Minor Permit Fee $200)
Dear Mr. Baker: ,
e North Carolina Department of Transportation (NCDOT) is proposing to widen; grade, and pave
Th
SR 1147, East Alarka Road, in Swain County from tha end el goad to a standardsl8 foot roadway s
This proposal entails widening and paving the existinb gr
The proposed improvements of SR 1147 have been identitie d NCDOT would like to perform these
improvements. Funds have been allocated for this proJec ,
activities sometime during the 2007-08 paving season.
I am sending astraight-line diagram with the proposed erothe roadt ~oss dsecotion~drawings foalpnpg
this project. In addition, I am sending a typical section of hic ma We propose to
culvert replacements as well tls below thecexisting sr tubed e evaton~s where bedrock is not
install the new culverts sligh y
encountered to minimize impacts to aquatic habitats and allow the existing stream gradients to
remain as unchanged as physically possible.
The North Carolina Natural Heritage Database was cords of 1 sted speciesf fordthelunnamed
threatened and endangered species. There are no re
tributaries of Little Alarka Creek. Additionally, there are no ek iordribfutarye does supportagood k
watershed. The Little Tennessee River, to which Alarka Cre
Alarka Creek is smaller and Fontana Lake
populations of several federally listed species. However,
has altered habitat within the lower reaches of Alarka Creek an been~surveyed prev ously w thouit n
between the two streams. Potential habitat in Alarka Creek has
yielding records of threatened and endangered species. The proposed impacts are on culvert
replacements and extensions are on small (2-4 feet) tributaries near the headwaters of Alarka Creek
and the gradient in the upper reaches is significantly higher than the occupied habitat along the
Little Tennessee River. For these reasons, we believe there will be "no effect" on threatened or
endangered species.
Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation Office
(SHPO) and the Office of State Archaeology determines that further investigations are required,
NCDOT will conduct the appropriate site investigations and obtain compliance from SHPO prior to
project construction.
The best management practices will be used to minimize and control sedimentation and erosion on
this project. The construction foreman will review all erosion control measures daily to ensure
sedimentation and erosion is being effectively controlled. If the planned devices are not functioning
as intended, they ~,vill be immediately replaced with better devices. The rock silt screens and other
erosion control devices will be in place prior to pipe culvert construction and will remain in place
until the project is stabilized.
Impacts to Waters of the United States
The unnamed tributaries are small; only the stream at site 5 is shown as a perennial stream on the
USGS topographic map. The streams appesilt~ The channels lack~veget hon.eFohtheselreasons,
channels are composed of gravel, sand and
we believe these streams are under the jurisdiction of the U.S. Army Corps of Engineers. In order
to construct the project in accordance with our current secondary road standards, it will be
necessary to impact waters of the United States in the Little Tennessee River Basin. Specifically,
NCDOT is requesting to extend/replace four metal culverts and relocate one roadside'seep in
unnamed tributaries to Little Alarka Creek (DWQ Class C). Listed below is a summary of the
proposed impacts.

Specifically describe measures taken to avoid the proposed impacts. It maybe 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. Culverts will be extended the
minimum length necessary to improve to meet current NCDOT standards. All pipe extensions
will be laced below the existing stream bed so natural substrate can be re-established. The
culvert installation sites will be de-watered to minimize im acts from sedimentation.
VIII. 1\Iitigation
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 January 15, 2002, 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 NCEEP 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~//h~o enr state nc us/ncwetlands/strm~ide.html.
