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
Britton Creek at the project reach drains about 3 5 square miles of mainly residential and commercial land uses The
project reach is adjacent to a City of Hendersonville sanitary sewer line and easement The channel, particularly the right
bank, is suffering from active bank erosion that is threatening sewer infrastructure The primary cause of the channel
instability appears to be a lack of deep rooted woody vegetation on the banks
3b List the total estimated acreage of all existing wetlands on the property
76
3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property
1500
3d Explain the purpose of the proposed project
The purpose of the project is to stabilize the eroding creek banks, thereby protecting the adjacent sanitary sewer
3e Describe the overall project in detail, including the type of equipment to be used
The project will involve sloping the right bank, installing bioengineering measures and placing stone toe reinforcement in
select areas where bank sloping and bioengineering practices are not feasible Conventional construction equipment will
be used, including a track mounted excavator, dump truck and assorted hand tools A pump- around flow diversion is not
proposed, but measures will be taken to limit the amount of construction traffic in the stream Some in- stream equipment
access will be necessary to construct the measures

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 stream and the larger French Broad watershed by stabilizing an eroding bank
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 Equipment will operate from the top of bank to the extent feasible,
but some in- stream equipment access will be necessary to install the stabilization measures The contract documents will
require well - maintained and functioning equipment and daily checks for leaks An emergency spill plan will also be required
