Tyson,
Thanks for meeting out the other day. As discussed, I had several questions relating to avoidance and minimization
efforts on the design that was included in the PCN which I've outlined below. Also we discussed mitigation requirements
in relation to past impacts which just on this parcel alone appear to be at least 200-300 linear feet of perennial stream
channel that has been culverted at some point in the past. So with that said, any additional stream impacts at this point
would trigger mitigation and a mitigation plan should be submitted with the PCN that adequately offsets impacts.
Mitigation ratios typically start at 2:1 unless you conduct NCSAM and depending on the results, potentially a reduced
ratio can be applied. With regards to avoid/minimization, please provide additional information/ clarification on the
following to continue the review of this application:
1. Please provide information as to why a second access/road crossing is needed for the facilities expansion and
will this crossing/area provide parking as well. It is also unclear from the plans the need to fill the entire length
of the stream channel versus just have a more narrow road crossing with retaining walls. Please discuss if
retaining walls could be used which would minimize impacts to the stream channel.
2. Also please address why other portions of the parcel that are currently open/not developed could not be used
for the facility which have existing pipes/culverts and would not require much if any additional stream piping.
Once I receive this information, I will review and provide follow up questions/comments as needed. Feel free to give me
a call with any questions, thanks.
