How is Wilmington zoned?
Wilmington regulates land through 24 zoning districts, and the largest by a wide margin is General Industrial at roughly 1,777 acres, nearly twice the largest residential district. That ranking reflects a port and manufacturing city where industrial land remains the dominant zoned category.
The waterfront carries its own family of four districts, numbered W-1 through W-4, running from waterfront manufacturing through waterfront manufacturing commercial and a low intensity manufacturing, commercial and recreation district to waterfront residential commercial. That last district is the largest of the four at roughly 405 acres. Having a graduated waterfront series rather than one designation lets the city transition its riverfront by degrees rather than all at once.
The residential districts are named by building type, which suits a city of historic rowhouse fabric: one family detached, one family semi detached, one family row houses, and row houses with conversions. One Family Row Houses is the largest residential district at roughly 963 acres. Apartment districts run low, low medium, medium and high density.
Commercial is graduated from neighborhood shopping through secondary business centres, central retail, central office and heavy commercial, with a special commercial district as well. Open Space covers roughly 478 acres. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
