Walnut Creek Aquatic Organism Passage Restoration Project
Macon County, North Carolina
Dear Ms. Higgins:
0 1 7 1 5 7 9
Wildlands has prepared design drawings for an aquatic organism passage restoration project along Walnut
Creek in Macon County, NC for the Mainspring Conservation Trust and the North Carolina Wildlife Resource
Commission (WRC). The project entails demolishing an existing, perched box culvert and replacing it with a clear
span bridge. Walnut Creek will also have structures installed within it and banks will be graded and planted to
help ensure the stability of the site. An Agent Authorization Form is attached which provides verification that
Sharon Taylor, the Executive Director for Mainspring Conservation Trust, is acting on behalf of Pine Grove
Baptist Church and Cheryl Duncan.
Project Overview and Proposed Impacts
Walnut Creek is classified as Class C; Tr water. Proposed construction along Walnut Creek is limited to
approximately 80 linear feet of stream with a short-term impact during the 2-3 week anticipated construction
period. Disturbance through the property is proposed along portions of both banks. The majority of existing
buffer vegetation at the site is maintained as short grass with some large trees along the top of bank of the
creek. A small section of the left bank at the end of the project consists of established trees, woody shrubs, and
herbaceous plants and will not be disturbed by construction.
The following additional information is being provided to support this request:
1. The impact on the buffer has been minimized by keeping the construction footprint as small as possible
and coordinating access and other project areas (staging is located in a nearby parking lot, etc.) to
minimize disturbance.
2. The disturbance will be a temporary impact and disturbed areas will be stabilized at the end of each day
with erosion control matting and straw mulch. The long term benefits include: reducing bank erosion,
establishing deep-rooted vegetation along the banks, and promoting aquatic organism passage
upstream by eliminating the perched culvert obstacle.

3. The top of bank and 25 -foot trout buffer are shown on an overview plan included with the plan set. The
area to be disturbed by project activities is denoted on the overview plan.
4. Project Narrative: As a first step, a pump -around flow diversion will be set up in the channel to divert
flow around the work area. The roof and interior walls of the existing box culvert will then be
demolished using excavators operating from the top of the bank. Excavators will be used to install in -
stream structures and grade the stream profile and banks. Disturbed banks will be seeded, mulched and
matted, and live staking will be used to establish deep-rooted vegetation on the banks. The replaced
bridge structure will be constructed after all in -stream work is complete.
5. Construction Schedule: A 2-3 week construction period is anticipated. Work efforts will be sequenced
to allow for stabilization of completed work at the end of each working day.
6. Erosion Control: The primary erosion control practices will include: the pump -around flow diversion, silt
fence around staging areas, and seeding, mulching and matting on the disturbed banks. Adjacent
floodplain areas will be seeded and mulched, or silt fence or wattles will be installed on the streamside
of the disturbance area if the area is to be subject to continued use for access to on-going work. Mulch
will be placed on all disturbed areas when rain is anticipated.
7. Other measures: The designer will be on-site to verify that erosion control measures are being installed
and maintained. Erosion control practices will be reviewed prior to anticipated precipitation and shored
up as necessary to maximize protection. Equipment fueling and maintenance will be required to occur a
minimum of 100 feet from the stream. It has been specified that equipment brought on-site must be in
good working order, clean and free of leaks.
Please find enclosed four copies of our PCN package for the subject project. We have included the following
supporting data:
• PCN form,
• Vicinity, USGS, and Site Maps,
• 11" x 17" copy of the 60% plan set,
Signed Agent Authorization Form, and
• Photolog.
This same information has been submitted to the US Army Corps of Engineers, NC Wildlife Resources
Commission, and Asheville USFWS office. If you have any questions, please contact me at 704.451.2177 or

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project represents a long-term benefit to Walnut Creek and the Cullasaja River as well as the larger Little Tennessee watershed by enhancing
aquatic habitat. The bottom, interior walls, and roof of existing box culvert will be removed, but the exterior walls will remain to support the new bridge
deck, helping to maintain the existing footprint of the original culvert area. Construction phase best management practices will help minimize the short-
term impacts, as described in below.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The project will begin only after all materials are stockpiled nearby. Equipment will operate from the top of bank to the extent feasible. The contract
documents will require well-maintained and functioning equipment and daily checks for leaks. An emergency spill plan will also be required
