Overlay District

An overlay district is a zoning tool that applies additional regulations or incentives to a specific geographic area, supplementing the underlying zoning code. 

Overlay districts are used to address unique conditions or goals, such as historic preservation, environmental protection, or urban design standards. They allow for tailored planning solutions without replacing existing zoning, enabling communities to balance development with conservation or revitalization objectives. Examples include historic districts, floodplain overlays, and transit-oriented development (TOD) overlays, which promote context-sensitive growth and enhance community character.
