CONCURRENCE MEETING
May 15, 2002
DESIGN CONSIDERATIONS
Proposed Widening of SR 1158 (Airport Blvd.) to a multi-lane facility, from NC 42
to US 264, Wilson County
State Project 8.2341801
Federal Aid Project STP-1158(2)
TIP Project U-3823
Introduction
The North Carolina Department of Transportation (NCDOT) 2002-2008
Transportation Improvement Program (TIP) includes a project to widen SR 1158 (Airport
Blvd.) from NC 42 to US 264 in Wilson County (see Figure 1). Studies are underway in
accordance with the National Environmental Policy Act (NEPA) of 1969, as amended.
Concurrence Point•No. 1 of the NEPA/404 Merger Process, developing the purpose and
need of the proposed action, was agreed upon at the last concurrence meeting held on
December 12, 2001. Concurrence Point No. 2 is agreement of design considerations.
Project Description
SR 1158 (Airport Blvd.) connects US 264 and NC 42. US 264 is a four-lane
divided facility that functions as an east-west radial serving traffic travelling into and
through the Wilson area. NC 42 also serves as an east-west radial. It is currently being
upgraded to a four-lane divided facility as part of TIP U-3472. Merck Road connects
with Airport Blvd approximately halfway between US 264 and NC 42. SR 1158 (Airport
Blvd.) is currently a 2-lane facility approximately 2 miles in length. TIP project U-3823
proposes to widen the two-lane se,;~;on to five-lanes with curb and gutter, except for a
section in the vicinity of Bloomery Swamp, which will be widened to four-lanes. A
typical section is attached (see Figure ~,).
Road Capacity
Current year (2000) daily traffic volumes along SR 1158 (Airport Blvd.) range
from 4,000-4,500 vehicles per day (see Figure 3). By the design year (2025), traffic
volumes along SR 1158 (Airport Blvd.) are expected to range between 21,600-22,000
vehicles per day (see Figure 4).

Project Purpose
The purpose of the project is to improve capacity and improve safety along this
section of SR 1158 (Airport Boulevard).
Project Need
^ Approximately 21,600-22,000 vehicles a day will pass along SR 1158 (Airport
Blvd.), resulting in a LOS F in the design year (2025).
Project Schedule/Cost
The project scoping meeting was held on February 28, 2000. A citizen
informational workshop was held on June 27, 2000. The purpose and need meeting was
held on December 12, 2001. Detailed environmental studies have been completed.
Right-of way acquisition for the project is scheduled to being in federal fiscal year
2004 and construction is scheduled to begin in federal fiscal year 2004.
The most recent cost estimates for the project are as follows:
TIP estimate Current estimate
Construction $ 6,300,000 Construction $5,650,000
Right of Way $ 1,200,000 Right of Way $1,200,000
Total: $ 7,500,000 Total: $6,850,000
Project Alternatives
Bridge vs. Culvert
Since the wetland system in Bloomery Swamp is determined to be of high-
qualiry, NCDOT is committed to looking at the reasonableness and feasibility of bridging
in this area. It should be noted that the Hydraulics Branch recommends extending the
existing culvert. Hydraulic analysis indicates that the existing culvert passes the 100-year
flood with no overtopping. Note: references below to wetlands restored are referring to
areas underneath the proposed bridges that are now filled, but have the potential to be
converted back to the wetlands.

Curb & Gutter vs. Shoulder Section
Much discussion took place at the last team meeting regarding curb & gutter vs.
shoulder section. NCDOT would like to reiterate our belief that a curb & gutter section is
the best choice for this project. Substantial development is expected to occur along
Airport Blvd. With such development come new driveways. Highway Division 4 feels
that a curb & gutter section will allow for safer driveways than a shoulder section would
provide. Driveway cuts in a curb & gutter section provide a concentrated area where
vehicles can be expected to pull on and off the roadway whereas shoulder sections
(especially those with a shallow ditch) have the ability to open up the entire frontage of a
property for vehicles entering/exiting the roadway. With projections showing a large
increase in traffic, this safety concern becomes more of an issue. It should also be noted
that the Division feels that the City of Wilson will require developers along Airport Blvd.
to put in curb & gutter as a condition of their development anyway.
In areas where runoff from the roadway is draining to Bloomery Swamp or the
other stream, grass swales (and curb & gutter) can be constructed to provide treatment
before eventual discharge. Other treatment techniques such as pre-formed scour holes,
level spreaders, dry detention basins, diffusing flow, etc. can be incorporated as well. In
areas where offsite drainage would reach the roadway, separate grass swales can be
constructed to keep it from commingling with the road runoff. Similar measures were
taken on the NC 42 widening, currently in construction, and in the vicinity df this project.
The specifics of such treatment measures are typically discussed during Concurrence
Points 4B and 4C. These techniques can be used to meet the requirements of the Neuse
Buffer Rules.
1. No-build
The no-build alternative would not meet the purpose of the project because it
would not improve capacity or safety along this section of SR 1158 (Airport Blvd.)
2. Alternate Modes of Transportation
Considering the size and location of Wilson, alternate modes of transportation are
,,,
not considered viable alternatives for the project. Implementation of passenger rail ~'
service and/or implementation of bus service in the project area would not meet the ~
purpose of the project.
*Note -The following alternatives contain a modification to the existing hydrology of
Bloomery Swamp. A railroad bridge crossing immediately upstream of Airport Blvd. is
approximately 175 feet long. This constraint on the wetland system is likely there to stay
and should be considered in the benefit/cost analysis.

3. Widening to S lanes, extend existing culvert, add equalizer pipes over Bloomery
Swamp
This alternative would widen the existing roadway to a five-lane facility with curb
and gutter. The horizontal cross section would be reduced to four lanes in the vicinity of
Bloomery Swamp to minimize impacts to wetlands. A sealed crossing would be installed
at the railroad crossing, including gates, signal flashers, and a monolithic concrete barrier
installed in the median leading up to the crossing. The existing five-barrel culvert at
Bloomery Swamp would be extended. Two equalizer pipes (one on each side of the
culvert) would be added to improve the hydrology. This alternative would impact
approximately 0.73 acres of wetlands. The estimated structure construction cost is
$205,000. The estimated total construction cost is $5,650,000. This alternative can be
seen in Figure 5.
4. Widening to 5 lanes and construct bridge 200-feet in length
This alternative would widen the existing roadway to a five-lane facility with curb
and gutter, and afour-lane section in the vicinity of Bloomery Swamp. A sealed crossing
would be installed at the railroad crossing, including gates, signal flashers, and a
monolithic concrete barrier installed in the median leading up to the crossing. This length
of the bridge (200-feet) would proi~ide adequate surface drainage to the highest quality
portions of the downstream wetland. Because of the higher contours in the pine-
dominated portion of the floodplain, attempts to flood these areas would not be
successful. The estimated structure construction cost is $1,050,000. The estimated total
construction cost is $6,420,000. This alternative can be seen in Figure 6.
5. Widening to S lanes and construct bridge designed to reciprocate the wetlands
impacted with wetlands restored
This alternative would widen the existing roadway to a five-lane facility with curb
and gutter, and afour-lane section in the vicinity of Bloomery Swamp. A sealed crossing
would be installed at the railroad crossing, including gates, signal flashers, and a
monolithic concrete barrier installed in the median leading up to the crossing. A
proposed bridge length of 475-feet would restore approximately the same amount of
wetlands as would be impacted by the fill. Approxirr~ately 0.50 acres of wetlands would
be impacted and 0.50 acres of wetlands would be restored. The estimated structure
construction cost is $2,430,000. The estimated construction cost is $7,800,000. This
alternative can be seen in Figure 7. Note that Figure 7 refers to a 460-foot long bridge,
this is incorrect. The correct estimate is 475-feet.
