MEMORANDUM
TO Lori Beckwith USACOE
Asheville Regulatory Field Office
FROM Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE March 30 2011
SUBJECT SR1591, Eastbrook Circle, Unnamed Tributary Hunting Creek Burke County
The NC Department of Transportation proposes to replace an existing bridge with a culvert
Biologists with the North Carolina Wildlife Resources Commission are familiar with habitat
values in the area These comments are provided in accordance with the provisions of the Fish
and Wildlife Coordination Act (48 Stat 401 as amended, 16 U S C 661 667d) and the North
Carolina Environmental Policy Act (G S 113A 1 through I I 3 10 NCAC 25)
The project will install a 50 x 81' x 59' aluminum pipe 60 x 60' CMP in a five (5) foot wide
stream channel Additional impacts to waters or wetlands are not indicated Including
dewatermg impacts will total 110 of stream The project is indicated to maintain existing
channel morphology The stream is lower elevation waters that are not known to support trout
or listed species however, these waters are classified as a water supply (WS IV)
Based on our review of the submittal we will not object to the project as proposed providing the
following conditions are implemented
Since a bridge is being replaced that allows relatively unrestricted floodplam
functions the pipe should be large enough to mimic floodplam conditions and pass
the stream without stream width restrictions The pipe should be large enough to
prevent erosive swirling above the pipe and hose nozzlmg below the pipe during
significant storm events Bedrock conditions can exasperate these issues if pipes are
not properly oriented and sized
