What is the definition of an "urban district"?

The definition of an "urban district" refers to areas where business or residential structures are situated at intervals of less than 100 feet. This signifies a concentration of development that distinguishes urban districts from rural or less-developed areas. The close proximity of structures suggests a more populated, developed environment, indicative of urban planning and land use that supports higher density living and commercial activities.

Other options do not meet the criteria for an urban district, as they describe characteristics of different types of areas. Options related to green spaces or zones lacking structures indicate suburban or rural settings, while agricultural zones are specifically tied to farming and open land use, which contrasts with the dense built environment characteristic of urban districts. Thus, understanding the spatial arrangement of structures is key to identifying an urban district, making the choice that indicates less than 100 feet between structures the correct definition.
