Doug and Sue,
Thank you for your comments. Our responses are below in red.
- First, what is that structure below those proposed house lots and what is the purpose? It is a stormwater pipe. The
outlet is better shown in the screenshot below. (It does not drain directly to the stream).
Second, why can't the road be shifted to the west and completely avoid the impacts? There appear to be plenty of
SWCs already proposed for this project and plenty of room.
- The SWC in question was required as a part of their fire safety plan. The proposed development was designed based
on the zoning requirements of the City of Mint Hill. Site layout and roadway connectivity were initially established with
1

previously approved plans for the subdivision. Based on the number of proposed lots and the requirements of the NC
Fire Code and City of Mint Hill, the residential roadway network layout requires two points of access in the vicinity of the
stream crossing. The proximity of the stream to the western boundary line limits the placement of these required
internal roadway access points. The stream crossing was chosen to be at the upper end of the stream to reduce the
need for culvert capacity and stream disturbance. I have attached the previous permit approval from 2007 for this
project.
Thanks,

Hey Aliisa,
