Hey, Sue and Cyndi. I'm sad that I won't get to be with you at the party next
Tuesday Very glad that you both and the Corps folks will be there.
I looked through the plan, and I'll also pass a couple FAA documents on to Cyndi
that may be helpful at the site visit. A few questions that came to mind...
1) The tree cutting is "isolated" - hopefully you can get a sense at the site visit
about how many trees will be left afterwards! Is this effort going to significantly
reduce the density of woody vegetation in the wetland areas? Is this an issue that
will repeat periodically when the remaining trees grow to a certain height or crown
size? Are there plans to plant shrubs which would provide woody veg without the
height issue of the trees?
2) The project layout sheet shows a runway "under construction by others." Was this
runway originally slated to be built in this location? It's <600' from areas in a
conservation easement and 1000' from wetlands that are now slated for tree
removal. Was it anticipated during the airport design that trees would become an
issue due to proximity to the runway? Note: the FAA documents recommend a
separation distance of 5000' to 5 miles between "air operations areas" and hazardous
wildlife attractants (such as wetlands) - it does not appear to be met in this case
(although I'm not sure how it would be possible on the Coastal Plain of NC!). There
is also an "area under construction by others" near the center of.the page, and I'm
curious what's being built there.
3) It looks like no clearing is planned for the Brush Creek mitigation area, part of
which is on sheet EP -107. I'd like to verify that, and find out if there are any
future plans for veg management in the wetlands adjacent to the area shown on the
sheet (or elsewhere on the airport property).
4) Cyndi mentioned that the Corps were the mitigation heavies on this permit, while
DWQ had stormwater on its shoulders. I'd like to hear what the Corps thinks in
relation to mitigation, and I wonder what potential issues there may be for the
stormwater treatment system that we need to address.
Good luck at the site visit. Please keep me posted, and let me know what I can do
to help.

thanks Tammy. If you see any big issues in their document can you call me and
chat with me about it before Tues. otherwise I'll just take notes and come back
to discuss with you about how DWQ will handle this. John Thomas mentioned its
possible that the USACE will be requiring a permit modification.

a boundary if it extends across the entire width of the floodplain. Additionally, other wetland types are considered boundaries for column

Hi Richard,
John Thomas left me a voice mail that the meeting is Tuesday. Can you
provide me with the exact time and a reminder of how to get to the
construction trailer please. I'll be coming and I think Cyndi Karoly is
going to try to attend also.

IThanks Sue. We are trying to schedule a field meeting with the Corps (John
Thomas and Jean Manuel) for as soon as possible - might be as early as next
Tuesday - if you (or other DWQ personnel) can't make that, we can be available

Richard,
I've forwarded this info to our Central Office. I'm not sure who in DWQ
will be the main contact, myself, or maybe Tammy Hill as our wetland
mitigation expert from the Central Office. I, or Tammy will be in touch
as soon as we've had a chance to review this and sort it out internally.

John:
Per our discussion, attached are the first 4 pages of the subject tree
removal plans which include clearing approximately 18 acres within
Conservation Easement and/or jurisdictional wetland areas. A complete
hardcopy set of the plans will be forwarded to you shortly.
One point of clarification - "Temporary Stream Crossing"s noted on the plans
are understood to be temporary crossings of permitted/constructed stormwater
II drainage conveyances - not jurisdictional streams or wetlands. Please let me II
II know your earliest convenient availability to field -review the areas proposed I)
I( for clearing and discuss the methods used to develop the plan. Thanks for II
