Oregon Air

We want to breathe clean air.

Oregon Air is opposed to Sky Harbour's proposed hangar expansion that would enable a 6X increase in jet flights into Hillsboro Airport (HIO) directly over Stafford, Tualatin, King City, Bull Mountain, Cooper Mountain, Beaverton, and Aloha. Currently 3-6 jet flights per day would increase to 16-30 per day by 2031. Flight altitudes would be less than 1500 feet feet above Cooper Mountain descending towards Hillsboro. Check out the Flight Path Map to learn more.



Oregon Air advocates for clean air and neighborhood livability in Washington County, Oregon. Founded in 2018 by a group of local residents who were impacted by offensive compost odors from Grimm's Fuel in Tualatin. As a result of community efforts, Metro provided Grimm's with a $750,000 grant for a $1.5M conversion to aerated static pile (ASP) composting. This has significantly reduced offsite odor complaints. In 2026, we installed a community air quality sensor in the Pony Ridge neighborhood to sample the air and collect real-time data.
