Water Quality Classification of nearest receiving water: C, Tr (Bradley); B (Little T) 2c. River basin: 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.
