DATE: February 3, 2003

SUBJECT: Review of 404 Permit Application, Kentucky Creek Enhancement Project, NC
Cooperative Extension Service, Avery County
The applicant is requesting a letter o? concurrence from the North Carolina Wildlife
Resources Commission (NCWIZC) to obtaina 404 permit: from the U.S. Army Corps of
Engineers. The NCWRC has reviewed information provided by the applicant, and field
biologists on our staff are familiar with habitat values of the project area. These comments are
provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.)
and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-6674).
The applicant proposes to improve water quality and aquatic habitat: values through
sediment: reduction practices and improved floodplain functionality. Bioengineering
methodologies will be used that should improve aquatic habitat values. Impacts will occur to
1,000 linear feet: of Kentucky Creek. Kentucky Creek is a designated wild trout stream ad the
North 'roe is a Designated Public Mountain l-rout Water. The North Toe River also supports
federal and state listed aquatic species.
Lased on the information provided by the applicant and our intormation on the range of
trout in the project area, we do not believe this project will cause significant effects to waters
supporting trout providing the following conditions are implemented:
1. instream work and land disturbance within the 25-foot wide buf('er zone are
prohibited during the trout spawning season of October 1.5 through April 15 to
protect the egg and fly stageq of trout from off-site sedimentation during
construction.
2. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion. Sediment and erosion control measures
shall adhere to the design standards for sensitive watersheds ( 15A N(-'A(' 413
.0024).

3. Temporary or permanent herbaceous vegetation should be planted on all bare soil
within 10 days (preferably 4ooner) of ground disturbing activities to provide
long-term erosion control. '
4. Native trees, herbs and warm season grasses should be incorporated into the
project to the extent practicable. Disturbed banks may be vegetated with silky
dogwood (Corpus amonum?, silky willow (Salix sericea), tag alder (A nus
serrulata), black willow (Sdrlix nigra), and sycamore (Platanus occidenlalis) or
other native riparian species to provide long term bank stability, stream shading
and improved riparian buff?r habitats. Note that silky dogwood, silky willow
and black willow can be planted as live stakes collected during the dormant
growing season. Cuttings should be randomly planted and done on 4 foot centers
from the waters edge to thetop of the bank. Trees should be planted on 10•-12
foot centers. Stream banks in these areas may also be seeded with an approved
wetland seed mix or tempoi;ary crop of wheat or rye.
5. Conservation easements or (deed restrictions are recommended that permanently
preserve undisturbed trout water buffers. These buffers should extend at (cast
twenty-tive feet from the top of each streambank.
Thank you for the opportunity to review and continent on this project. If you have any
questions regarding these comments, please contact me at 336/769-9453.

Re: Permit Application for Kentucky Creek Enhancement Project
Please find enclosed a completed Pre-Construction Notification (PCN) Application Form
and a stream restoration design for Kentucky Creek in the Town of Newland in Avery
County. The purpose of the project is to improve water quality and aquatic habitat by
reducing sedimentation; to improve stream stability; and to improve riparian and
floodplain functionality of 1,000 feet of Kentucky Creek. The project meets the DWQ
definition of stream restoration and therefore a permitting fee is not included with
this package. The project is funded by Avery County, Tennessee Valley Authority, and
Trout Unlimited. This is not a stream mitigation project.

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.
The project will enhance stream stability by protecting streambanks providing grade control,
improving bed features and reducing sediment concentrations in the stream Stream impacts
during construction will be minimized by working from the streambank and limiting ground
disurbance to only those areas in the immediate vicinity of instream structures.
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.
Page 9 of 12
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/ncwetiands/strmgide.html.
I . 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.
