An increasingly common land use pattern allows for subdivisions with smaller lot sizes and little or no setback and sideyard requirements while keeping the same density ratios. These are known as:

• A. Cluster zoning
• B. Green belt
• C. Planned unit developments
• D. Agricultural preserve

Answer: (C)

Planned unit developments are a zoning approach that lets a developer create a master plan for a neighborhood with flexible standards, such as smaller lots and reduced or waived setbacks and side-yard requirements, while keeping the overall density the same as under conventional zoning. The idea is to cluster homes and provide shared open space or common amenities, which preserves density but allows more efficient layout and design flexibility. This matches the pattern described: smaller lots with little setback yet the same density. The other options represent different concepts—green belts and agricultural preserves are protective open-space or farmland tools, while clustering is related but not the formal development framework that guarantees a master plan and flexible standards.
