Dear Sir:
The purpose of this letter is to request a modification to the United Stated Army Corps of Engineers
(USACE) Section 404 Individual Permit and North Carolina Division of Water Resources Section 401
Certification for the above referenced project. The original 2014 permit application and subsequent 2016
and 2017 modifications (referenced above) presented final impacts far R-2915A, R-2915B, R-2915C, and
R-2915D. This inodification presents changes to one permit site in the B Section needed as a result of a
wing wall modification at the outlet of the new culvert at Site 1 B to prevent the wing wall from extending
into Gap Creelc. The angle of one wing wall has been changed to better tie it into the existing stream
bank, resulting in 20 linear feet of additional bank stabilization along Gap Creek to prevent the culvert
wing froin being undernlined during high water events.
All changes in llnpacts due to tl�e additional bank stabilization at Site 1B in the B Section are in red
itcrlics. Please see the enclosed revised permit drawings for Section B.
Summary of R-2915 Jurisdictional Impacts:
The preliminary projected impacts for the overall (Sections A-E) project will be approximately 3.11 acres
of permailent wetla��d in�pacts, 0.15 acre of teinporary wetland impacts, 8,776 linenr f'eet of pernianent
st��eam inzpacts (6,983 linear feet of fill and 1,193 lineao� feet of bank st�bilizrltion), and 0.34 acre of
temporary stream impacts (see Tables 1 and 2 for a breakdown of impacts by Section).

MITIGATION
At this time, DMS is providing compensatory mitigation for Sections A, B, C, and D impacts. Table 5
summarizes the total mitigation needs as 2.59 acres of wetlands impacts and 6,578 linear feet of stream
impacts. No urlditic�nrr[ rnitiKati�jt is reyuire�l �lue to the a�l�led strerrn� buiTk s7abilizaiio�� �rt Site IB in
the B Section ��s it does taot corrstitute a loss of'water. Compensatory mitigation for Section E will be
provided accordingly during the subsequent permit modification. This modification will occur when final
design on the remaining Section has been completed.
