Subject: R-5705 (NC 55 Corridor Study) Concurrence Point 3
Discussion
Hi to all,
The subject project has gone through the Merger Process, and the Merger Team was
ready to meet to discuss Concurrence Points 2A and 3(CP2A - Bridging Decisions, and
CP3 - LEDPA (Least Environmentally Damaging Practicable Alternative)). After meeting
internally and with the Corps and NC DWR, I thought the meeting issues could instead
be addressed by email. I would like to address each one here. If everyone is ok with
handling this by e-mail instead of having a meeting, let me know.
The items to be discussed are:
• Concurrence Point 2 Discussion
• CP2A Discussion
• LEDPA Discussion
• Future Merger Meetings
Concurrence Point 2 Discussion
The merger team meeting to discuss Concurrence Point 2(CP2; Alternatives Selected for
Detailed Study) was held on September 13, 2017. The merger team agreed to carry
forward Alternatives A(widening NC 55 along the existing alignment) and B(Western
Bypass). NCDOT requested concurrence from the merger team of choosing alternatives
from three corridors: the two alternatives mentioned earlier, and Alternative C(Eastern
Bypass). NCDOT staff noted that previous discussions occurred and had focused on
keeping Alternatives A& B and dropping Alternative C, since Alternative B is expected to
attract more traffic, and Alternative C impacts more wetlands. CAMPO mentioned
(from their prospective) selecting a bypass west of Angier could impact future plans for
US 401. This issue was and still is a concern for the future for CAMPO, but not enough
to impact the decision for this project. All signatory agencies of the Merger Team signed
the CP 2 form.
CP2A Discussion
The following proposed hydraulic structures were discussed. The size and locations are
based on preliminary data; drainage area, aerial mapping, and LIDAR. Minimization
opportunities will be looked at during the design phase when surveys are available:
• For Alternative A:
o A existing 8' x 4' RCBC will be extended in kind, 30-feet upstream and
33-feet down stream, at Station -L- 341+55 +/-.

• For Alternative B:
o A new 7' x 6' culvert will be installed at Station -L- 197+74 +/-,
approximately 212 feet in length, and
o Two 6' x 6' culverts will be installed at Station -L- 312+59 +/-,
Approximately 208 feet in length.
• For both Alternatives:
o An existing 30-inch RCP will be replaced by a 6'x6' at Station -L- 558+82
+/-, approximately 106 feet in length, and
o An existing 8' x 4' RCBC will be replaced by an 8' x 6' RCBC at Station -L-
587+60 +/, approximately 177 feet in length.
LEDPA Discussion
Attached is an impact matrix for Alternatives A& B. Note the number of businesses,
wetlands and streams impacted by each alternative. Yes, Alternative B does impact
more wetlands than Alternative A(due to the Alternative B being a new location
option), but it impacts fewer businesses than Alternative A. There are also no
competing resources.
Future Mer�er Meetin�s
Due to the low number of impacts for each alternative, and lack of competing resources,
I would like to request removing this project from the Merger Process at the CP2 point
and return to the Merger Process at Concurrence Points 4A (CP4A; Avoidance and
Minimization) and 4B (30% Hydraulic Review). We will move forward with selecting the
western corridor (Alternative B) as the selected alternative. Right-of-way is scheduled
for January 2020 and construction is scheduled for January 2022.
Please let me know if you have any comments or questions regarding these
measures. Hopefully this email is not confusing, I wanted to make sure the above
information sent was correct.
