Dulles International Noise Contour Map Update

The Metropolitan Washington Airports Authority is undertaking an effort in 2018 to update the noise contour maps for Washington Dulles International Airport. The objective of this effort is to provide updated noise contour maps that can help guide land use compatibility planning in the region.

(Please Note: The noise contour map update effort for Dulles International is unrelated to the Airports Authority's efforts working with the communities surrounding Ronald Reagan Washington National Airport (DCA) through the DCA Community Working Group.  For information on the DCA Community Working Group activity, please click here).

There are several reasons the Airports Authority decided to embark on this effort at this time:

  • There have been changes in the aviation environment since the early 1990s, when the existing Airport Overlay Districts were established, and the future vision for Dulles International should reflect these changes.
  • Flight tracks and overall utility of the airfield at Dulles International have evolved and will continue to evolve with implementation of FAA’s NextGen modernization program.
  • The FAA is modifying flight procedures to allow for the triple simultaneous runway operations at Dulles International during low visibility conditions or Instrument Flight Rules (IFR), which will likely increase utility and capacity at Dulles International.

The progress for this noise contour map update effort can be viewed here. The noise contour map process generally includes:

  1. Inventory | Evaluate current and future plans, describe existing operation conditions
  2. Forecast | Determine full-build scenarios, determine maximum potential operations, determine potential aircraft runway use and flight tracks
  3. Noise Modeling | Calculate existing aircraft noise exposure levels, calculate potential aircraft noise exposure levels for full-build scenarios, determine appropriate composite of potential scenarios
  4. Conclusions | Recommend potential aircraft noise exposure contour for land use planning

To update the noise contour maps for Washington Dulles International Airport, the Airports Authority formed a Local Jurisdictional Stakeholder Working Group, comprised of Airports Authority interdisciplinary staff, appointed professional technical staff from local governments (including Fairfax County, the Town of Herndon and Loudoun County), our airline partners' representative and key Federal Aviation Administration officials whose participation will be essential to the success of this effort. The noise contour map update process will involve regular meetings of the Working Group during the next ten months with work concluding by or before February, 2019. Fairfax County, Town of Herndon and Loudoun County professional staff on the Working group have been named to the Working Group by their respective County Executive, Town Manager and County Administrator. Staff were chosen from these three localities because a noise county map update for Dulles International is essentially a mapping effort, with a product outcome that most directly guides local land use planning in the immediate geographic vicinity of the Airport. 

Local government staff participating in the Working Group are listed here:   

Periodically, the Airports Authority will post information online that is relevant to the noise contour map update process. This information may also include material that has been reviewed by the Working Group. During 2018, new information was posted in April, June, August and November. In 2019, new information was posted in February. Individuals who wish to access this information can click below: 

Three times during this process, the Airports Authority has hosted Public Workshops on-site and at a location near Washington Dulles International Airport. The Public Workshops included an opportunity for individuals interested in this process to personally visit with noise contour map update subject matter experts who are familiar with the effort underway at Dulles International.

Consolidated information and comments from the June 27th and June 28th Public Workshops is posted here.   A synopsis of the comments recevied during these two Publuic Hearings has been summarized as Answers to Frequently Asked Questions (FAQ's).  Click here for the FAQ's from the June 27th and June 28th Public Workshops.

Throughout this process and during the Public Workshops, the Airports Authority welcomes questions, comments and general input from the larger community. You can submit questions and comments at any time -- and, based on comments or input received, this webpage may be updated with answers to Frequently Asked Questions.

On April 19, 2019, the Metropolitan Washington Airports Authority formally requested that Fairfax County and Loudoun County consider integrating the updated noise contours into their land use planning. Copies of this correspondence is found here:
