    Metadata Updated: September 2, 2022

    More MetadataThe Airport Impact (AI) Overlay District is a zoning overlay district administered by the Loudoun County Department of Building and Development.  The Department is responsible for all development approvals, review procedures, modifications and density calculations in the AI as governed by Article IV, Division C: "Environmental Impact Districts", Section 4-1400 of the Revised 1993 Zoning Ordinance.

    (1)  Washington Dulles International Airport:  The FAA PART 150 Noise Compatibility Programs, Washington Dulles International Airport, August, 1992, and

    (2)  Leesburg Municipal Airport:  Environmental Assessment Report.  October, 1985.
