Re: Nationwide Permit Application
Action Id. 2006-20, Kingfish Bay
Dear Kimberly,
'IEVVR -1~+ATcFi QUALiI'Y
W~TLANL? P,~~Tn?~~'4`~AT~P,?RA.~IGH
Per your request for additional information dated on April 25th, 2007
regarding the Kingfish Bay Development in Brunswick County. Listed below
is discussion of each issue in your letter dated Apri125"', 2007.
1) Impact area 4 is needed to provide access to the proposed building. The
design of the proposed access road is necessary to facilitate traffic flow
and emergency vehicle access. Parking will be located under the
proposed building.
2) Multiple access/egress points are not feasible due to the adjacent
properties to the east and west being under private ownership. Access
to the property is only available from NC Hwy 179 on the north side of
the property.
Wetland impacts have been minimized by utilizing existing road
crossings and minimal side slopes/retaining walls. The applicant
explored the possibility for bridging, but due to the cost analysis,
concluded that it was not feasible.
3) In addition to providing access to uplands, this proposed impact is
needed to create a circular driveway that will provide access to parking
underneath the building. Even if the road was moved to the uplands
between W30 and W107, this wetland impact would still be needed to
create this circular driveway. Furthermore, the proposed building and
driveway could not be moved further west without creating additional
wetland impacts from grading. Engineered grading limits have been
determined to provide no additional impacts to wetlands onsite.

4) Limits of proposed disturbance have been established outside of all
wetland limits except where previously noted.
5) All proposed wetland impacts have been shown on submitted plans.
Utilities will be installed within the road right of way to avoid
additional impacts.
6) 48" culverts will be installed at the stream crossings to maintain
connectivity and allow biological passage. Culverts will be buried 12"
below ground to maintain a natural bottom.
7) Onsite stream restoration or creation is not possible due to several
factors. No formerly impacted streams exist on site, and all existing
streams are in good condition. Please note that the non-impacted
streams and wetlands located on site will be preserved in perpetuity,
and the EEP has agreed to provide necessary mitigation for the
proposed impacts.
If I can be of any assistance during your review of the application please feel
free to contact me at you convenience. We will be glad to meet with you on
site if needed.
Sincerely,
C-~ G--a-
