Subject: Nationwide 14 & 33 Permit Application
Hiwassee Dam High School Access Road
Cherokee County
State Project No.: WBS 41355 (DWQ Minor Permit Fee $200)
Dear Mr. Baker:
The North Carolina Department of Transportation (NCDOT) is proposing to extend an
access road to Hiwassee Dam High School off of NC 294 in Cherokee County. This
proposal entails a small section of road on new location to connect to a section, which
was completed in the summer of 2006. Funds have been allocated for this project, and
NCDOT would like to perform these activities sometime during the 2007 paving season.
I am enclosing a PCN application, cross sections, pipe installation details, photographs, as
well as a marked county map and USGS quad map. We propose to install a new culverts
slightly below the existing streambed elevations where bedrock is not encountered to
minimize impacts to aquatic habitats and allow the existing stream gradients to remain as
unchanged as physically possible.
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 will be immediately replaced with
better devices.
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

area. In addition, The North Carolina Natural Heritage Database was checked for records of
threatened and endangered species. There are no records of listed species for the Thompson
Branch watershed. Riparian habitat along Thompson Branch has been impacted from cattle
grazing and poor land use practices throughout the watershed. Impacts associated with the
culvert installations should be minimal. This project will have "no effect" on threatened and
endangered species.
Impacts to Waters of the United States
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 Hiwassee River Basin. Specifically,
NCDOT is requesting to install 40 linear feet of new culvert in Thompson Branch (DWQ Class:
C), and extend an existing culvert 201inear feet in an unnamed tributary to Thompson Branch.
In addition, we propose to impact a small wetland area (0.009 Acres), comprised of a depression
in an old pasture, which is fed by stormwater runoff from the adjacent fire department building
and parking lot. Below is a summary of the proposed impacts.

Page 6 of 10

were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Original roadway features were not designed to accommodate school traffic including cars and
buses. Impacts (pipe len hs, etc.) were minimized to the maximum extent practical to construct
the new road to current NCDOT secondary road standards. Pipes will be installed sli hg_tly below
the existing streambed elevation to provide aquatic life passage during_periods of low flow.
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 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 maybe 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 (see DWQ website for most current
version.).
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.
If mitigation is required for this protect, NCDOT will make payment to the NCEEP.
Page 7 of 10

2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
