RE: Approval with conditions of the Traffic Impact Analysis (TIA) associated with the proposed
Sidbury 187 (Gore Tract) residential development in New Hanover County, North Carolina.
Dear Mr. Anastopoulo:
The WMPO, NCDOT and New Hanover County staffs have reviewed the Sidbury 187 TIA (sealed April 08, 2024).
This approval letter with conditions has been revised to reflect ongoing construction along US 117 (N
College Road) and SR 1318 (Blue Clay Road) and as a result several of the required phase 1 improvements
have been reassigned to Phase 2 of the development. Based on the information provided and conversations
held to date, it is our understanding that the proposed development will be built out in three (3) phases and
consists of the following land uses:
Phase 1 (build year 2029):
o ITE Land Use Code 210 –324 Single Family detached housing
o ITE Land Use Code 215 –144 Townhomes
Phase 2 (build year 2030):
o ITE Land Use Code 210 – 601 Single Family detached housing
o ITE Land Use Code 215 –268 Townhomes
Full Build (build year 2032):
o ITE Land Use Code 210 – 1312 Single Family detached housing
o ITE Land Use Code 215 – 442 Townhomes
Based upon the review of the analysis provided, the following improvements are required of this development:

Provide yield control for all approaches.

If changes are made to the proposed site driveways and/or land uses, the current trip distribution may need to

WMPO, and New Hanover County, in which instance this approval would become null and void.
The applicant is required to obtain all applicable New Hanover County and NCDOT permits for access to the road
network. A copy of this TIA approval shall be included with any NCDOT driveway permit application. All applicable
NCDOT and New Hanover County technical standards and policies shall apply.
