Subject: [External] U-5828 (NC 54 Bypass/McCrimmon Pkwy Phase II) Permit
Modification Request
Good afternoon James and Rob,
On behalf of the Town of Morrisville, Kimley-Horn is submitting the attached
modification request for the TIP# U-5828 (NC 54 Bypass/McCrimmon Parkway) Phase II
project in Morrisville, Wake County, NC. The project was originally permitted in May
2017 and proposes to construct Phase II of the NC 54 Bypass project (NCDOT TIP# U-
5828) in Morrisville to extend McCrimmon Parkway from Airport Boulevard to Aviation
Parkway at Evans Road. The proposed roadway will be four lanes wide with median to
accommodate existing traffic loads and reduce congestion along the NC 54 corridor.
The project is being constructed in coordination with NCDOT, and following their review
of the permitted impacts, NCDOT has requested the Town modify the permit to allow
for more improved outlet protection and bank stabilization at the culvert outlets.
NCDOT stated that they have seen bank-only protection fail on multiple NCDOT
projects, and the Town proposes to utilize countersunk riprap at the culvert outlets to
provide long-term stabilization while not resulting in any loss of waters or stream
function. Additionally, a design change was made at Site 7 which reduced the length of
the culvert under the proposed road. As shown in the attached revised impact tables,
the use of countersunk riprap rather than bank-only stabilization and the shortened
culvert will result in 96 LF of additional permanent impact (with no loss of waters)
spread between sites 2, 3, 4, 5, and 7. This modification has reduced the temporary
disturbance by 86 LF. The areas changing as a result of this modification have been
called out via red text in the attached revised PCN table. As a result, the proposed
changes in the impact totals will require less mitigation due to the addition of
countersunk riprap and a shortened culvert. The proposed stream mitigation has
decreased from 752 linear feet to 694 linear feet.
Similarly, these changes in design have resulted in changes to the previously permitted
buffer impacts. As shown in the attached revised tables, permanent buffer impacts at
Site 3 have increased by 2,756 square feet in Zone 1 and 676 square feet in Zone 2.
Buffer impacts at Site 3 have been deemed Allowable with Mitigation, and as a result,
the mitigation required has increase. The proposed buffer mitigation has increased from
165,746 square feet to 175,028 square feet.
Additionally, small modifications to wetland impact sites 4, 6, 7, and 8 are proposed to
stabilize the inlets at culvert installations and prevent future erosion and down-cutting
of the wetland substrate as water flows into the correctly-installed pipe (which places
the invert below wetland substrate). The anticipated erosion/down-cutting has been
observed by NCDOT on similar roadway projects, and the modification will help prevent
this problem. The modified impact quantities have been called out via red text in the
attached revised PCN table, and the net change resulting from the modification at each
site is included next to each quantity. The net result of the wetland modifications is an
increase of 0.008 acre of permanent impact and a decrease of 0.061 acre of temporary
i m pact.

6i. Comments: Unavoidable impacts to the riparian buffers of streams SD, SE, and SH will result from the road construction. The
riparian buffers will be crossed perpendicularly to minimze impacts. According to the NRB Buffer Rules, impacts at Site 2 are
"allowable" (road crossings that impact greater than 40 LF but equal to or less than 150 LF), and impacts at Sites 1 and 3 are
"allowable with mitigation" (road crossings that impact greater than 150 LF or 1/3rd-acre of riparian buffer).
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to jurisdictional wetlands, streams, and riparian buffers have been avoided and minimized to the extent practical. The
alignment will tie into the existing section of McCrimmon Parkway to minimize new construction length and impacts. The
alignment has been located along the topographic ridge as much as practical to avoid larger stream and wetland systems
located in the bottomlands adjacent ot the project area. The alignment was also located intentionally to minimize earthwork and
grading required, reducing the required fill slopes along the alignment and limiting stream and wetland impacts.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to streams within the corridor will be minimized to the extent practical throughout the construction process by avoiding
stream and wetland features where practical. Equipment staging and construction access will be located in upland areas
throughout the corridor, and silt fencing will be installed around the permitted limits of distrubance to ensure all equipment is
located within the project corridor at all times near stream and wetland areas. Sediment control measures will be used to reduce
stormwater impacts to receiving waters and minimze runoff from the construction sites.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for � Yes ❑ No
impacts to Waters of the U.S. or Waters of the
State?
2b. If yes, mitigarion is required by (check all that apply): � DWQ � Corps
� Mitigation bank
2c. If yes, which mitigation option will be used for this
project? ❑ Payment to in-lieu fee program
� Permittee Responsible Mitigation

Mitigation credits for the proposed project will be provided from the "Morrisville Community Park Stream & Riparian Buffer
Mitigation Site" as discussed with the USACE and NCDWR and multiple meetings and in communications through late 2016
and early 2017. The mitigation site will provide 694 linear feet of stream mitigation credits, and will provide 175,028 square
feet of riparian buffer mitigation credits.
6. Buffer Mitigation (State Regulated Riparian Buffer Rules) — required by DWQ
6a. Will the project result in an impact within a protected riparian buffer that � Yes ❑ No
requires buffer mitigation?
6b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation. Calculate the
amount of mitigation required.

Zone 2 Road Construction 26,501 1.5 39,752
6f. Total buffer mitigation required: 175,028
6g. If buffer mitigation is required, discuss what type of mitigation is proposed (e.g., payment to private mitigation bank,
permittee responsible riparian buffer restoration, payment into an approved in-lieu fee fund).
Mitigation for unavoidable impacts to riparian buffers of stream SD and SH will be provided by the "Morrisville Community
Park Stream & Riparian Buffer Mitigation Site". The mitigation site will provide 175,028 riparian buffer credits as discussed
outlined in the NCDWR closeout documentation for the mitigation site and as confirmed by NCDWR at various meetings and
in conversations held in late 2016 and early 2017. Mitigation credits have been fully constructed and closed out with
NCDWR and the USACE.
