What is an overlay zone and a plan district?

Overlay zones consist of regulations that address specific subjects that may be applicable in many areas within the City.

Plan districts consist of regulations that have been tailored to a specific area of the City.

Both overlay zones and plan districts are applied in conjunction with a base zone and modify the regulations of the base zone.
