If the district in which such a project will occur is outside a city's central business district (as that district is defined by resolution of the city council, which definition is binding and conclusive), then, of the private development forecast for a development project by the development financing plan for the district in which the project will occur, a maximum of twenty percent (20%) of the plan's estimated square footage of floor space may be proposed for use in retail sales, hotels, banking, and financial services offered directly to consumers, and other commercial uses other than office space. The twenty percent (20%) limitation in the preceding sentence does not apply to development financing districts located in a development tier one area, as defined in G.S. 143B-437.08 and created primarily for tourism-related economic development, such as developments featuring facilities for exhibitions, athletic and cultural events, show and public gatherings, racing facilities, parks and recreation facilities, art galleries, museums, and art centers.
The total land area within development financing districts in a unit, including development financing districts created pursuant to G.S. 160A-515.1, may not exceed five percent (5%) of the total land area of the unit. For the purposes of this section, land in a district created by a county that subsequently becomes part of a city, town, or incorporated village does not count against the five-percent (5%) limit for the city, town, or incorporated village unless the city, town, or incorporated village and the county have entered into an agreement pursuant to G.S. 159-107(e). A county may not include in a district created pursuant to this section any land that, at the time the district is created, is inside a city, town, or incorporated village.
