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.

Total buffer impacts 48,587 30,440 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.

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.
