Dear reviewer:

MAR 8 2013
This letter describes site conditions and presents the proposed streambank stabilization
efforts for the subject project. The work is being sponsored through partnerships with
the NaturalResources Conservation Services and the US Fish and Wildlife Service.
Watauga Creek is classified as Class C trout water.
The project site is located in a FEMA regulatory floodplain; per direction from the local
floodplain administrator, the work will be documented in a post - construction Letter of
Map Revision.
Site Conditions
The project site is located along Watauga Creek, north of Franklin between US Highway
441 and the Little Tennessee River. Work is proposed at three sites along a roughly
3,000 linear foot (LF) reach where agricultural practices and buffer clearing have lead to
bank erosion problems. Over the past several years, bank erosion has caused loss of
land, undermining of fences and mature trees, and mid - channel sediment deposition.
Land on the Brown property (right bank looking downstream) is used for pasture and
row crops. The Stiles property on the left bank is used for pasture, while the Thweatt
and Maribona properties on the left bank are both sparse young forest.
Watauga Creek at the downstream end of the project reach drains a 7.6 square mile
watershed. Based primarily on field surveys of bankfull indicators but also on regional
relationships, the bankfull discharge is estimated at 340 cubic feet per second.
Proposed Stabilization Measures
The stabilization design is based on natural channel design principles. The primary
goal is to create a design cross section and profile that transport the water and
sediment delivered to the stream by its watershed in a state of dynamic equilibrium.

Confluence Engineering conducted a detailed existing conditions assessment, which
included topographic surveys of the creek and floodplain areas, sediment sampling and
testing, and an evaluation of site constraints such as property boundaries and mature
trees. We used assessment data to inform the design, which is presented on the
attached plans.
Impacts to the trout buffers will be temporary, lasting only as long as the stabilization
work lasts. Work is expected to begin shortly after the trout moratorium ends in April
2013 and is expected to last for three to four weeks.
The design attempts to minimize sediment impacts through the following practices:
• The contractor will be required to mobilize all equipment and materials necessary
for stabilization work before beginning any stream work. The contractor will also be
required to stage and store equipment and materials outside of the trout buffers.
• Sediment fence will be installed on the stream side of stockpiles and staging areas.
• A stabilized temporary stream crossing will be installed to allow equipment access
to both banks while protecting underlying soils.
• The contractor will be required to stage his work such that disturbed areas will be
stabilized with seeding, mulch and erosion control matting (where appropriate) prior
to the end of each work day.
• A pump- around flow diversion will be used to dewater all in- stream work areas.
Closure
Thanks for your consideration of this request. If you have any questions, please contact
Jason Meador (Aquatic Program Manager) at 828.524.2711 ext. 309.
