On January 17, 2023, the Loudoun County Board of Supervisors (“BOS”) approved changes to Loudoun County’s Airport Impact Overlay District (“AIOD”). The AIOD is a zoning designation for properties susceptible to airport noise at or above specified levels. Properties located within the AIOD are subject to land use regulations intended to mitigate the impacts on homebuyers in the affected areas and to prevent residential development in areas where the highest noise impact is expected to occur.
