A large roof can still have a tight ground footprint. Airspace, street use, and active loading areas have to fit the same plan.
State field guide
North Carolina’s original five guides cover a two-state metro, a coastal-border community, the capital region, and two Piedmont manufacturing centers. Durham joined in a separate city-proper population pass. Each place changes the airspace, access, weather, and ground-control questions that belong in an early lift study.
The original guide set follows the five largest metropolitan statistical areas containing North Carolina territory in the Census Bureau’s July 1, 2025 estimates. Metropolitan divisions are excluded. Moyock serves as the North Carolina planning anchor for the second-ranked Virginia Beach-Chesapeake-Norfolk metro because it is a Census-defined place in Currituck County with an adopted county small-area plan. Durham-Chapel Hill ranks sixth among those metros. Whole-metro counts select the original guides and do not measure city population or lifting demand.

A large roof can still have a tight ground footprint. Airspace, street use, and active loading areas have to fit the same plan.

An occupied street can be harder to clear than an open roof. Durham’s utility work and planned manufacturing campus make the ground footprint worth mapping first.

Interstate access and an airport manufacturing campus do not erase the separate controls on ramps, industrial parcels, and public roads.

Open-looking parcels can still be constrained by drainage, homes, roadside utilities, and one busy route to the Virginia line.

Airport traffic, freight routes, and occupied research campuses make the support path as important as the rooftop set point.

The local airport schedule, a city closure permit, and overdimension ground transport can all affect the same work window.
