RE: Approval with conditions of the Traffic Impact Analysis (TIA) associated with the proposed
US 421 Industrial Park development in New Hanover County, NC.
Dear Mr. Smith:
The WMPO, NCDOT, and New Hanover County staff have reviewed the US 421 Industrial Park development
TIA (sealed September 11, 2023). Based on the information provided and conversations held to date, it is our
understanding that this development will be built in two (2) phases and consist of the following land uses:
Phase 1 (build year 2024):
o ITE Land Use Code 130 – 500,000 SF Industrial Park
Full Build (build year 2033)
o ITE Land Use Code 130 – 3,000,000 SF Industrial Park
Based on review of the analysis provided in the TIA report, the following improvements are the responsibility of
the developer:
US 421 and I-140 EB Ramps (Existing Signalized Intersection)
Phase 1
• No improvements are required.
Full Build
• Extend the existing eastbound I-140 Off-Ramp right turn lane to provide 300 feet of storage, and
desirable full-width deceleration and taper.
• Extend the northbound right turn lane on US 421 to provide 675 feet of storage, and desirable full-
width deceleration and taper.

US 421 and I-140 WB Ramps (Existing Signalized Intersection)
Phase 1
• No improvements are required.
Full Build
• Extend the existing westbound I-140 Off-Ramp left turn lane to provide 400 feet of storage, and
desirable full-width deceleration and taper.
• Extend the existing westbound I-140 Off-Ramp right turn lane to provide 300 feet of storage, and
desirable full-width deceleration and taper.
• Extend the existing southbound right turn lane on US 421 to provide 300 feet of full-width storage,
extended back to the existing South Atlantic Services driveway access.
US 421 and Existing Access (Existing Unsignalized Intersection)
Phase 1
• No improvements are required.
Full Build
• Install a traffic signal and incorporate it into the existing closed loop system.
US 421 and Access B (Proposed Signalized Intersection)
Phase 1
• Install a traffic signal and incorporate it into the existing closed loop system.
• Construct Access B with one ingress lane and two egress lanes, configured as a left turn lane and a
thru-right lane.
• Provide an internal protected stem of 250 ft as measured from the right-of-way line.
• Construct a northbound right turn lane on US 421 with 100 feet of storage, and desirable full-
width deceleration and taper.
Full Build
• Reconfigure Access B as a left turn lane and a left-thru-right lane.
• Extend the northbound right turn lane on US 421 to provide 200 feet of storage, and desirable
full-width deceleration and taper.
If changes are made to the proposed site driveways and/or use, the current trip distribution may need to be
modified and would require a revised Traffic Impact Analysis to be submitted for review by the NCDOT, WMPO,
and New Hanover County, in which instance this approval would become null and void.
