What is an "overlay district"?

An "overlay district" refers to a specific zoning classification that is superimposed over existing zoning districts. This concept allows local governments to apply additional regulations and guidelines to particular areas without altering the underlying zoning classifications that are already in place.

The overlay district can be used to achieve various goals such as preserving historical character, protecting environmentally sensitive areas, promoting certain types of development, or managing specific land uses within a defined area. By layering these additional regulations on top of the existing zoning, communities can target specific issues or characteristics of a neighborhood while maintaining the overall structure of the existing zoning plan.

This distinction is important because it highlights how overlay districts facilitate more nuanced planning and development strategies that address specific community needs or characteristics, rather than completely revamping existing zoning codes.
