U-5828 (NC 54 Bypass/McCrimmon Pkwy Phase II) Permit Modification Request
U 5828_McCrimmon - Phase 2 PCN Modification Pages 201E0619.pdf; Attachments
On behalf of the Town of Morrisville, Kimley-Horn is submitting the at[ached 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 construc[ Phase II of the NC 54 Bypass project (NCDOTTIP# U-5828) in
Morrisville to extend McCrimmon Parkway froin 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 6eing 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 wlvert outlets. NCDOT stated that they have seen bank-only protection fail on multiple NCDOT projeds, and the
Town proposes to utilize countersunk riprap at the wlvert outlets to provide long-term stabilization while not resulting
in any loss of waters or streain function. Additionally, a design change was made at Site 7 which reduced the leng[h 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 impad 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 irnpacts 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 impact.
