This modification will result in changes to the previously permitted stream impacts as well as impacts to
wetlands and riparian buffers. Wetland impact changes at Site 9 were a result of construction
methodology and stream impact changes were due to a request for stabilization at the culvert inlet and
ditch tie to the stream. Total stream impacts at Site 9 have not changed; however,the type of impact
changed. Wetland impact type has changed at Permit Site 9 from mechanized clearing to excavation in
wetlands,but the footprint of impact is unchanged.Wetland impact type has changed at Permit Site 20
from mechanized clearing to excavation in wetlands,but the footprint of impact is unchanged. Wetland
Site 27 is new and increases wetland impact by 0.01 acre (ac.) for a total of 12.46 ac. of permanent
wetland impact. Riparian buffer impacts have changed at Sites 18 and 23. Buffer Site 23 impact changes
are due to the construction of a Multi-Use Path(MUP)at the Town of Cary. Buffer Site 18 impacts
changed due to a small sliver of Buffer Zone 1 and Buffer Zone 2 being missed in the original permit
application that has now been incorporated near Y13RPD—Station 18+62.53. Riparian buffers will
increase 27 square feet(sq. ft.)in Buffer Zone 1 and will increase 2,088 sq. ft. in Buffer Zone 2. Please
see the enclosed revised permit drawings and updated impact summary sheets which reflect the
changes in impacts. We are requesting a modification to the Section 404 USACE Authorization
#SAW-2009-02240 and the 401 Water Quality Certification,Number 4179.
Stream Impacts
As recommended by NCDOT, Site 9 now includes bank stabilization along both banks at the inlet of the
66"RCP on Y1 OA due to the ditch tie to the stream and for future stability of the channel banks. As a
result,culvert stabilization increased 20 ft. from 115 ft. to 135 ft. due to the addition of bank stabilization.
Wetland Impacts
The Design-Build contractor has determined the topographic grade for the culvert diversion located at
Permit Site 9 on the R-2721B Section,is such that an at grade pipe installation cannot be constructed
without excavating in a portion of the mechanized clearing impact area. The areas which need to be
changed from mechanized clearing to excavation for construction of the culvert diversion are located on
the inlet and outlet side of the 6'x8' RCBC. The contractor realized they would need to excavate in this
mechanized clearing area to have enough room to construct the bench required for the special lateral 2'
base ditch(Detail 13-10). There will be an additional 0.054 acre of temporary excavation for the culvert
diversion. The total temporary excavation at Site 9 is 0.06 acre. These impacts were previously mitigated
as mechanized clearing.No additional mitigation is proposed.
At Permit Site 9 in order to create a haul road to YIOA, fabric was placed in a mechanized clearing area
of the wetland and temporary fill was placed on top of the fabric in order to maintain existing ground
conditions after the temporary fill is removed. This area is the only access point from the mainline due to
conflicts with shallow waterlines in this area and is needed to grade YIOA. The temporary haul road
impacts are 0.07 ac.; however,temporary impacts are not mitigable, so the impacts are still shown as
mechanized clearing in the permit impact summary table since this is the permanent impact to the wetland
but illustrated as temporary fill on Permit Drawing Sheet 27A.
Due to these changes at Permit Site 9, excavation increased from<0.01 ac.to 0.07 ac. The footprint of
impacts are unchanged, and impacts were previously mitigated as mechanized clearing.
During construction of the permanent ditch at Permit Site 20 a portion of the mechanized clearing was
changed to excavation(Station Number 486+132 -RT)in order to have room to construct the ditch. Due
to these changes at Permit Site 20, excavation increased from 2.25 ac.to 2.29 ac. The footprint of
impacts are unchanged, and impacts were previously mitigated as mechanized clearing.

Also,the Design-Build contractor is now extending a Multi-Use Path for the Town of Cary. The MUP
extension is located near the Bells Lake Road(Y8)interchange. This site has been labeled Permit Site 27
and is located on Permit Drawing Sheet 20C. The MUP design is governed by the American Association
of State Highway and Transportation Officials (AASHTO). The MUP has already been shifted as far
away from the wetland area as possible while still meeting the deflection angle requirements of this code.
To tie to the existing MUP at the appropriate angle a portion of the wetland will be impacted resulting in
an increase of permanent fill by<0.01 ac. and an increase of 0.01 ac. for mechanized clearing.
Buffer Impacts
Buffer Site 23 on Buffer Permit Drawing Sheet 8A of 19 is a new impact site created by the need to tie
the new section of the MUP into the existing MUP at the appropriate angle as well as a small buffer area
near Oxford Green Road(Buffer Permit Drawing 8 of 19)both requiring a portion of Buffer Zone 2 to be
impacted. This will increase buffer zone 2 impacts at Buffer Site 23 by 1,444 sq. ft.
Buffer Site 18 has changes to buffer impacts in both Buffer Zone 1 and Buffer Zone 2. The change in
impacts at this site is due to a small sliver(Y13RPD—Station 18+62.53)of Buffer Zone 1 and Buffer
Zone 2 being missed in the original permit application and has now been incorporated. Buffer Site 18 had
an increase of 27 sq. ft. for Buffer Zone 1 and an increase of 644 sq. ft. for Buffer Zone 2.
Revised Impacts Summary R-2721B
Jurisdictional stream impacts,jurisdictional wetland impacts, and riparian buffer impacts have changed,
as presented in this modification request. The new proposed impacts to jurisdictional wetlands total 12.46
ac. of permanent riparian wetland impacts. Total stream impacts remain the same,however bank
stabilization increased by 20 feet. The new proposed Buffer Zone 1 impacts increase 27 sq. ft., and the
total Buffer Zone 2 impacts increase 2,088 sq. ft. This modification request results in changes to Tables
3, 12, 14, 15, and 24 of the previous permit application/modifications. No changes to the other tables
were required so they are not included in this modification request.

Bolded mitigation amounts represent a change from the original issued 404(SAW-2009-02240)/401 WQC(4179)and
subsequent modifications/revisions.
Currently NCDOT has acquired mitigation for R-2721B from NCDMS to compensate for 14.64 ac. of
wetland impacts. The mitigation amount required for the modification of wetland impacts,after the changes
addressed above, is 12.46 ac. which is below the wetland mitigation acquired by 2.18 ac. The new
excavation impacts reported in Revised Table 12 are not counted towards mitigation due to the excavation
areas occurring within areas previously permitted and mitigated as mechanized clearing. Therefore, no
other changes to the required mitigation for wetland impacts are necessary due to this wetland modification
request. The original Neuse Zone 1 riparian buffer impacts request was for 582,622 sq. ft. This amount
exceeds the 557,299 sq. ft. needed by 25,323 sq. ft. The original Neuse Zone 2 riparian buffer impacts
request was for 387,313 sq. ft. This amount exceeds the 375,426 sq. ft. needed for Neuse Zone 2 impacts
by 11,887 sq. ft.No additional buffer mitigation is being proposed for this modification. The buffer impact
amounts for R-2721B were multiplied by the appropriate mitigation ratios to calculate the proposed
mitigation amounts in Table 24 (2:1 for streams and wetlands, 3:1 for Zone 1 riparian buffer impacts, and
1.5:1 for Zone 2 riparian buffer impacts).
