New York-based Sky Harbour Group is trying to build a private jet hub at Hillsboro Airport (HIO) for 30 large private jets that would cause a significant increase in jet flights and jet noise over Tualatin, King City, Progress Ridge, Beaverton, Aloha, Hillsboro, and North Plains, passing 2,300 feet above Bull Mountain, and 1,500 feet above Cooper Mountain. We have filed a land use appeal to fight this, and we need your help to fund it:

Negative Impacts of Sky Harbour's Proposal:

• Frequent noise events under the flight path and near the airport
• Air Pollution: Ultra-fine particles, VOCs, black carbon, NOx, CO2
• No limitation on operating hours. No cap on jet flight activity
• Hangars would be located directly across the street from the library.
• Library and sidewalks would be hit with with jet blast and loud jet noise.
• Reduction in property values and quality of life

The flight path could be right above your house: [map]

Carbon Footprint

Private jet travel is the most carbon-intensive mode of passenger transport.
Fuel Consumption for a Private Jet: (Bombardier Global 7500)

• Burns 1000 gallons of fuel the first 30 minutes of flight (take-off and climb)
• Burns 500 gallons per hour at cruise speed. 700 gallons per hour at top speed
• 14X more pollution per-passenger-mile than a commercial jetliner
• Average fuel economy of 1 mile per gallon (1 MPG)

Realtime Flight Monitoring

If you want to know if the plane that just flew over your house is heading to Hillsboro, check the real-time tracking map on ADS-B Exchange. If you click on an airplane, it will show you their entire flight path.

No New Business Will Come Because of This Project

• The Port has provided no evidence that this project will attract new companies to Washington County. Companies choose locations based on: tax structure, cost of doing business and workforce availability
• Private jet convenience is not a site selection factor. Intel is a perfect example: They chose this region for tax benefits and workforce, not the airport.
• Landing private jets is a perk, not a driver of economic development. This project benefits wealthy private jet owners, not the local economy.

Don’t Blame Residents — They Bought Near a Non Commercial Airport

• The Hillsboro Airport is officially classified as a non commercial, non cargo, General Aviation airport. Homes near HIO are not discounted on Redfin, Zillow, or RMLS because the airport has historically had very low jet activity.
• Many residents have lived here 20–40+ years. They bought near a small plane airport, not a private jet hub. The sudden shift to 16–30 private jets per day is a major change in airport use and it deserves a full environmental impact study. This is not a case of “you should have known better.” It is a case of residents facing impacts they were never warned about.
