DCA Airplane Noise Assessment Project

The Public Community Meeting for the DCA Noise Study was held on Thursday, September 20th, 2018 at the Georgetown Day School (Lower/Middle School) at 6:30 pm. Please access the agenda and presentation for more details.

In fiscal year 2017 (FY2017), the District of Columbia initiated a study to investigate noise originating from Reagan National Airport (DCA) air traffic operations and to identify ways in which to minimize the noise effecting District residents in a manner acceptable to the Federal Aviation Administration (FAA) standards and criteria. The District’s ultimate goal is to assist FAA and the Metropolitan Washington Airports Authority (MWAA) in implementing the new Next Generation Air Transportation System (NextGen). The result of this project would be specific recommendations to FAA and MWAA for changes in Air Traffic Control (ATC) procedures to minimize noise exposure and impact to District communities while not adversely affecting the FAA’s goals of air safety and promotion of air transportation.

DCA Noise Study

The DCA Airplane Noise Assessment project is expected to accomplish the following:

  • Review all published DCA approach and departure procedures, prior noise studies, previous noise measurement reports, noise complaint files, noise monitoring data and DCA Roundtable records.
  • Model past and current noise exposure from DCA operations over the District using FAA’s Aviation Environmental Design Tool (AEDT).
  • Monitor noise exposure at locations in the District to validate noise modeling results.
  • Conduct sleep awakening analyses for District neighborhoods significantly affected by nighttime DCA flights.
  • Assess noise impact, per national standards for classroom disruption, for two schools in the District.
  • Develop alternative ATC routes and modifications to existing routes.
  • Develop recommendations for presenting to MWAA and FAA for their consideration.
  • Document conclusions and recommendations in a comprehensive assessment report.

A grant was issued in FY2017 and this Phase I effort involved background research, field noise monitoring data analysis, noise environment modeling and development of preliminary findings.

Fiscal Year 2018 Project (Phase II)

In FY2018, District awarded a grant to CSDA Design Group to continue the DCA Airplane Noise Assessment study. This study (Phase II) will build and expand on the previous year’s effort, for incorporating various supplemental noise metrics suggested by the U.S. Department of Defense (DOD) Noise Working Group (Technical Bulletin: Using Supplemental Noise Metrics and Analysis Tools, DOD Noise Working Group, December 2009). The grantee will develop comprehensive assessment reports.
