Maryland Lawmakers Push FAA to Reroute Noisy, Polluting Flights Near BWI

Nearly two years after the FAA concentrated departing jets onto a single corridor above Severn, Maryland, Sens. Chris Van Hollen and Angela Alsobrooks and Rep. Sarah Elfreth told the agency its proposed five-year repair schedule was unacceptable. The three Maryland Democrats sent a letter to FAA Administrator Bryan Bedford pressing him to accelerate changes to the concentrated flight path from Runway 15R that has subjected communities south of BWI Thurgood Marshall Airport to what the lawmakers called "harmful ultrafine particulate matter and constant noise."

The FAA had set that five-year clock in a letter dated February 19, 2026, telling the Maryland Department of Transportation and the BWI Community Roundtable that adjustments to Runway 15R departure procedures would arrive "up to five years" out, with safety projects taking priority. The specific change both the Roundtable and the lawmakers want: eliminate a navigational waypoint called WARYN, positioned south of the airport, and replace it with a minimum altitude restriction designed to scatter departing aircraft across a wider corridor rather than funneling them over the same rooftops. Done correctly, the adjustment could reduce average daily noise exposure for the hardest-hit neighborhoods by up to five decibels.

The path implemented in 2024 pushed aircraft noise in the surrounding communities to levels reaching 69 decibels, roughly the intensity of a hair dryer held to the ear. Residents across Severn, the Elmhurst neighborhood east of the airport, Parole and Edgewater in Anne Arundel County, and Elkridge and Columbia in Howard County live below this corridor. Some of those families sit eight to 15 miles from BWI yet report jet traffic loud enough to stop outdoor conversations mid-sentence.

The problem is an intensification of one dating to 2015, when BWI adopted the FAA's NextGen satellite-based navigation system. The technology allowed more aircraft to operate closer together in the same airspace, which meant planes began tracking identical paths over the same homes day after day, well past dark and before sunrise. By 2021, BWI logged more than half a million noise complaints in a single year, with Severn consistently among the communities filing the most.

The health consequences compound over time. A University of Maryland study estimated that BWI's flight-path noise will generate more than $40 million in additional healthcare costs per year over the next three decades, a cumulative burden approaching $800 million. Researchers have linked sustained aircraft noise to cardiovascular disease, coronary heart disease, anxiety, and depression.

The FAA said it would respond directly to the lawmakers. Residents who want their data counted by federal regulators can file complaints through the Maryland Aviation Administration's online noise portal; the volume of documented submissions is among the primary metrics the FAA and the Roundtable use when determining which flight path reviews move to the front of the queue.
