Airport Impact Overlay District

  1. Project Overview

    Loudoun County has initiated a Comprehensive Plan Amendment (CPAM) to update the county’s airport noise policies related to the Airport Impact Overlay District. The Airport Impact Overlay District indicates where airplane noise is anticipated to affect residential, school and commercial buildings. The current overlay district was implemented by the Board of Supervisors in the early 1990s to both prevent residential development in areas that would be affected by aircraft noise and mitigate impacts to prospective homebuyers.  

    The Metropolitan Washington Airports Authority updated the noise exposure maps for Dulles Airport in 2019. The update reflects changes in the aviation environment in the last 30 years and prepares for future changes in airport usage. Loudoun County is amending its 2019 Comprehensive Plan to update the district.

    The public is invited to learn more and provide input on the proposed new overlay district boundaries and policy changes. View the project webpage.
