Homebuyer Information Guide: Overlay Districts
If you are considering buying a home or land in Loudoun County, you will want to know if it is in an Overlay District.
An overlay district is used to establish alternative land development requirements within a specific area of the county that requires special attention, such as an environmentally sensitive area or rapidly developing corridor.
The overlay is usually superimposed over conventional zoning districts. It consists of a physical area with mapped boundaries and written text spelling out requirements that are either added to, or in place of, those of the underlying regulations.
The county's overlay districts include, but are not limited to, the Airport Impact Overlay District, Floodplain Overlay District, Historic Districts
, Limestone Overlay District, Mountainside Development Overlay District, and Quarry Notification Overlay District.
For example, the Airport Impact Overlay District was established to acknowledge the unique land use impacts of airports, regulate the siting of noise sensitive uses, ensure that the heights of structures are compatible with airport operations, and complement
Federal Aviation Administration regulations regarding noise and height.
The Loudoun County Zoning Ordinance
provides detailed information about the county's overlay districts. The Loudoun County Online Mapping System
also includes overlay district information.
