Hey Dave,

Our project manager and contractor for Avery bridge #1 has requested a change to the permitted plans, regarding a
stormwater device. The requested change is in regard to structure 409, which is a drop inlet/box and 15” RCP that will
deliver stormwater to rip rap on the bank and into the Linville River. I’ve attached the plans and the 401 permit above,
and a snapshot of the area below (see black oval).

They would like to replace the box and 15” pipe with a rock lined ditch. That’s actually what is in place now, and it
seems to be functioning well, even with all the rain we have had in recent weeks. We still plan to have the rip rap on the
bank, to dissipate the stormwater that leaves the ditch. I figured replacing a pipe with a ditch would be preferred – not
that either is great habitat, but I’m assuming the rock lined ditch will be better habitat for critters that the 15”
pipe. Since it was part of the plans that were permitted with the 401, I wanted to seek your approval before making the
change. Also, wanted to clarify that it is a stormwater measure, so no jurisdictional features should be impacted by the
change.

Let me know if you need additional information.

Thanks, (and this should be my least email to you for the day!:))

Kevin
