RE: Approval of the Traffic Impact Analysis (TIA) associated with the proposed
Dairy Farm Road
New Hanover County, NC
Dear Ms. Brown,
The WMPO, NCDOT, and New Hanover County staffs have reviewed the Sidbury Crossing Traffic Impact
Analysis sealed July 8, 2020. This approval is based on the following land uses as proposed in the TIA:
320 apartments (LUC 221 Multifamily Housing Mid-Rise)
Based on review of the analysis provided in the TIA report, the following improvements are required by the
developer:
SR 1336 / SR 1572 (Sidbury Road) at SR 2181 (Dairy Farm Road) (stop-controlled full movement T-
intersection)
o Extend the eastbound left turn lane to 275 feet of storage (or maximum available without
modifying the bridge).
o Construct a westbound right turn lane with taper only.
o Construct a southbound left turn lane with 50 feet of storage, 50 feet of full width deceleration,
and 200 feet of taper.
SR 1336 / SR 1572 (Sidbury Road) at SR 1318 (Blue Clay Road) (stop-controlled T-intersection)
o Realign the intersection to provide stop control for the southbound approach only, allowing the
eastbound and westbound approaches to operate free flow.
US 117 (N. College Road) at SR 1318 (Blue Clay Road) (signalized full movement intersection)
o Construct a westbound right turn lane with 150 feet of storage, 50 feet of full width deceleration
and 200 feet of taper.
o Extend the westbound left turn lane ~150 feet to connect to the two-way left-turn lane.
o Revise signal.

SR 2181 (Dairy Farm Road) at Site Access 1 (proposed stop-controlled full movement intersection)

o Provide stop control for the eastbound approach.
o Provide 100 feet of internal protected stem on the eastbound approach.
o Design site access according to NCDOT standards
SR 2181 (Dairy Farm Road) at Site Access 2 (proposed stop-controlled full movement intersection)
o Construct the site access with one ingress and one egress lanes.
o Provide stop control for the eastbound approach.
o Provide 100 feet of internal protected stem on the eastbound approach.
o Design site access according to NCDOT standards.
SR 2181 (Dairy Farm Road) at Site Access 1 (proposed stop-controlled full movement intersection)
o Construct the site access with one ingress and one egress lanes.
o Provide stop control for the eastbound approach.
o Provide 100 feet of internal protected stem on the eastbound approach.
o Design site access according to NCDOT standards.
If changes are made to the proposed site driveways and/or land 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. This approval will become null and void.
The applicant is required to obtain all applicable County and NCDOT permits for access to the road network. All
applicable NCDOT and County technical standards and policies shall apply.
Please contact me at 910-772-4170 with any questions regarding this approval.
