Answer:
Bulk zoning
Step-by-step explanation:
Bulk zoning refers to zoning regulations designed to decrease the population density of a specific area. Generally cities apply very strict bulk zoning regulations on residential areas, which should be used specifically for building homes. If you limit the maximum height of the constructions, even if you build a condominium it must not have more than 2 or 3 floors.
Sometimes bulk zoning regulations are also applied to commercial areas that are located far away from the central district. This is specially useful when you wish to separate city areas through the use of extensive commercial areas that are located on specific avenues. For example, north of ABC avenue the zoning regulations allow tall buildings, while south of that avenue only houses can be built.
