What is an Overlay Zone?

An overlay consists of a mapped area which is subject to additional standards in excess of your zoning to ensure protection of a specific resource or guide development within a certain area. For example, in Oregon City there are five overlay districts including:

  • Willamette River Greenway Overlay District: Protection of views from the Willamette River
  • Natural Resource Overlay District: Protection of streams, wetlands and wildlife habitat
  • Historic Overlay District: Preserve historic properties and districts with design standards
  • Flood Management Overlay District: Assure the floodplain does not increase in size and all structures within the floodplain are safe
  • Geologic Hazards: Protection of sloped, landslide and other hazardous areas
