Little Tennessee
3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Bradley Creek drains about 2.8 square miles of mixed forest, pasture and low density residential land uses. The 450 -LF
project reach of Bradley Creek has incised to meet the elevation of Little Tennessee River, which it flows into at the
western property boundary. The incision and a lack of riparian vegetation has led to bank erosion and sediment pollution.
The project also includes a 150 -LF reach of the right bank of the river, where bank erosion is threatening the Henson's
field and causing excess fine sediment to reach the river.
3b. List the total estimated acreage of all existing wetlands on the property:
0
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
750 LF (Bradley) + 600 LF of the right bank of the river
3d. Explain the purpose of the proposed project:
The purpose of the project is to stabilize the eroding banks and creek bed, thereby protecting adjacent land and reducing
the amount of fine sediment pollution and protecting downstream aquatic habitats.
3e. Describe the overall project in detail, including the type of equipment to be used.
The project will involve sloping banks and creating floodplain benches on Bradley Creek and the right bank of the river.
Log vanes will be used in the creek bed to direct to flows to the center of the channel and encourage pool formation for
habitat enhancement. Graded banks will be seeded with temporary and permanent (native) seed mixes, covered with
coir matting and live staked with native woody species. Conventional construction equipment will be used, including a
track mounted excavator, dump truck and assorted hand tools. A pump - around flow diversion will be employed to
dewater the work area on Bradley Creek.
4. Jurisdictional Determinations
4a. Have jurisdictional wetland or stream determinations by the
Corps or State been requested or obtained for this property /

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 the creek and larger Little Tennessee watershed by stabilizing an eroding banks
and reducing fine sediment inputs. 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 will begin only after all materials are stockpiled nearby. A pump - around flow diversion will be employed to dewater the
work area on Bradley Creek and reduce the potential for downstream sediment impacts. Equipment access across the creek
will be provided by a timber mat, which will span the creek and limit disturbance to banks and bed. For work on the river,
equipment will operate from the top of bank. The contract documents will require well- maintained and functioning equipment
and daily checks for leaks. An emergency spill plan will also be required.
