Action Items Identified at April 10, 2012 CP3 (revisited) Meeting
Below is a summary of action items identified at the April 10, 2012 CP3(r) meeting. Resolution of
these action items is described in detail in the CP3(r) meeting summary:
• Traffic Forecasting & Capacity Analysis— Request for clarification of analysis.
Status: Expanded description of analysis to be included in FEIS.
• Red-cockaded Woodpecker- Request for clarification of effects.
Status: Updated description of effects to be included in FEIS.
• Hickman Hill Convenience Center - Request for continued coordination with local area.
NCDOT has initiated continued coordination with Craven County.
Status: Resolution will be addressed during right-of-way acquisition phase.
• Stream Mitigation— Request for clarification on mitigation of stream impacts.
Status: Question resolved via reference to "Croatan Mitigation Bank Addendum to the
NCDOT UMBI (May 2009)." (Pages 9 and 10).
• Bridge Lengths — Bridge length recommendations have been clarified and are described in
this packet.
• Corridor 2 Relocations — Requested review of Corridor 2 relocation to investigate possibility of
minimizing.
Status: Additional design review and coordination between NCDOT and USACE was
conducted. It was determined that the Lake Road interchange configuration and location
could not be altered sufficiently to avoid the relocations as reported.
Alternative 3 (LEDPA) Preliminary Design
The Preliminary Design for the Least Environmentally Damaging Practicable Alternative (LEDPA)
is shown in Exhibit 2a-d overlain on aerial photography. The LEDPA is a four-lane highway that
is divided by a 46-foot depressed median. The controlled-access facility extends from just south
of Lewis Farm Road on existing US 70 to south of McCotter Boulevard on US 70, and is
approximately 10.3 miles long. The preliminary design includes interchanges at the north and
south termini with existing US 70 and at Lake Road (SR 1756).
The horizontal alignment matches the preliminary design and corridor hearing map with the
exception of the proposed railroad bridge clearances and the paved shoulder width. The
preliminary design included 27-foot bridge clearances over existing railroads in three locations:
two over the North Carolina Railroad, and one over the Camp Lejeune Railroad. In the design, all
three of these crossings have been lowered to provide 23-feet of vertical clearance. The three
railroad bridges are all adjacent to proposed interchanges. Thus, reducing the proposed
clearance also reduces the footprint of the bridge approaches and the immediately adjacent
segments of the interchange ramps and side roads.

The currently proposed shoulders associated with the preliminary design are 12-feet wide with
10-feet of pavement.
Avoidance & Minimization to Date
The Detailed Study Alternative designated as Alternative 3 was selected as the LEDPA in
December of 1996 and then reaffirmed by the Merger Team in April of 2012. The alignment of
Alternative 3 was designed to avoid or minimize impacts to the human and natural environments
to the extent possible including the City of Havelock, Marine Corps Air Station — Cherry Point,
streams, wetlands, and RCW clusters on National Forest System lands.
In January of 2001, an Interagency Merger Process Team meeting was held to discuss
avoidance and minimization for the LEDPA. The horizontal alignment of the current preliminary
design has not changed since the functional design alignment discussed in 2001. Thus, the
current LEDPA includes the following minimization measures that were agreed upon by the
Interagency Merger Process Team on 1/18/2001:
• No ditching in wetlands
• 46-foot median
• Bridging over the Southwest Prong of Slocum Creek
• Bridging over the East Prong of Slocum Creek
After the LEDPA selection and following the publication of the 2011 DEIS, NCDOT has
coordinated with USFWS and USFS in a continued evaluation of RCW impacts associated with
the LEDPA and in accordance with Section 7 of the Endangered Species Act. Based on this
evaluation and coordination, which will be described in the FEIS, it was determined that an
attempt should be made to reduce the cleared width of the proposed project for a specific section
of highway to facilitate RCW activity. Information developed during this coordination directed that
a cleared 200-foot width would be the goal in a specific segment of alignment.
NCDOT Natural environment section conducted further RCW studies, and in coordination with
them NCDOT Roadway Design and Hydraulics Units, revised the roadway cross section to result
in a 200-foot cleared width from station 338+00 to station 393+00 (Exhibit 2b). The reduced
width was accomplished by re-design of the slopes, but maintains the median and shoulder
widths required by the design criteria for this facility.
To date, the additional minimization of impacts due to the revised design includes impacts to
wetlands (reduction of 9 acres), forested area (reduction of 5.5 acres), and the Southwest Prong
Flatwoods Natural Heritage Area (reduction of 1.5 acres). Table 2 shows the updated impacts
based on this design revision.

1. The number of build-condition impacts is lower than the number of no-build condition impacts (49) because
the proposed bypass will reduce sound levels in some locations and some residences will be taken for right
of way.
2. Impact quantities are based on the construction limits of the Preferred Alternative plus an additional 25 feet
buffer, in accordance with current NCDOT impact analysis guidelines. Direct impacts are projected to be
less than those shown in the table.
3. The proposed project may affect, but is not likely to adversely affect, the red-cockaded woodpecker.
USFWS concurrence with this biological conclusion is based,in part,on NCDOT's agreement to allow periodic
closures of the Preferred Alternative in order for CNF staff to conduct prescribed burns as management for
the RCW. Without this agreement, the USFS would be unable to conduct the necessary prescribed burns in
the vicinity of the project thus causing an indirect adverse effect on the RCW

Hydraulic Structure Recommendations (CP2A)
The Detailed Study Alternative designated as Alternative 3 was selected as the LEDPA in
Discrepancies in recommended bridge lengths, as listed in the September 6, 2011 DEIS and the
June 20, 2002 Avoidance and Minimization (CP4B) meeting minutes, have been previously noted
and discussed by the interagency team. Follow up analysis was conducted by NCDOT PDEA
and NCDOT Hydraulics Units and documented in an email to the team on July 17, 2012. Details
of this coordination are included in the April 10, 2012 Concurrence Point 2A meeting summary.
Based on the analysis and verification described above, Table 3 lists the recommended major
drainage structures for the LEDPA.

Updated Wetland Impact Calculations
A systematic error in the calculation of wetland impacts was discovered subsequent to the
publication of the DEIS. The error resulted from conversion/scaling issues in transferring data
between GIS and Microstation. The miscalculation resulted in reporting the wetland impacts for
each of the Preliminary Alternatives lower than actual measured areas. The conversion error
only applied to wetland impacts. Table 4 below shows the difference.

Table 4 shows that the reported impacts for each of the alternatives increased from 25-31 acres
based on the update. It should be noted that the LEDPA (Alternative 3) showed the highest
wetland impacts when originally selected. This has not changed, and its corrected impacts also
exhibited the lowest total increase of corrected acreages. For example: selection based on the

original numbers included consideration that Alternative 3 impacted six acres more than
Alternative 1 (a 6% difference). The updated numbers show that Alternative 3 impacts five acres
more than Alternative 1 (a 4% difference). Therefore, the corrected wetland acreages (and their
impact difference among alternatives) serve to further validate the selection of Alternative 3 as
LEDPA.
Documentation of this change will be included in the FEIS.
Stream & Wetland Impacts
Tables 5 and 6 show anticipated stream and wetland impacts associated with the LEDPA. The
stream and wetland impact calculations are based on the preliminary design footprint (slope
stakes) plus an additional 25 feet. The updated quantities are based on the latest design which
incorporates the previously described reduced cross section from station 338+00 to 393+00.
