Aircraft Noise - What is the City Doing? 
The City is aware of the recent increased flight activity over parts of Cupertino from various area airports, including San Jose International Airport (SJC), San Francisco International Airport (SFO), and smaller airports such as Palo Alto (PAO) and San Carlos (SQL). This has impacted some Cupertino neighborhoods near the Sunnyvale border.

The City has no direct authority over airspace and is limited in its ability to address resident aircraft noise concerns. However, the City is committed to preserving and enhancing the quality of neighborhoods by maintaining or reducing the levels of noise generated by transportation facilities, including airports. Based on resident complaints, the City is closely monitoring actions by the San Mateo County Board of Supervisors and their efforts to reroute specific incoming SQL flights over Sunnyvale and parts of Cupertino.

What Can I Do? 
To aid our efforts, and to better inform discussions with Congressman Ro Khanna and the FAA, we encourage you to voice your concerns with the operating entities directly responsible for the noise/traffic. If aircraft noise is bothering you, the best thing that people can do is to contact the appropriate airport. Providing the airport with as much detail as possible will help with recording an accurate report. The FAA has also coordinated an ombudsman to gather and log complaints for the region. Please include the FAA Aviation Noise Ombudsman when filing complaints.

Identifying Aircraft
When contacting the appropriate agency, it is best to have some identifying information about the aircraft. All aircraft flying in this area are on radar and can be tracked (click on "View WebTrak"). This site allows you to click on a particular aircraft to see the tail number, current altitude, and speed (Image A) and includes current decibel readings at various noise monitor sites (Image B); a legend is also provided which shows the types of aircraft displayed (Image C).

Where to Report?
Airports are responsible for their noise impact on the communities they occupy. These noise impacts include noise from arrivals and departures, as well as noise from aircraft in a flight path within the immediate vicinity of the airport. Most airports have staff that respond to airport noise issues, or you can ask for the airport manager. Airport noise issues and concerns should first be addressed to the appropriate staff at the local airport. Many airports also have their noise abatement information and contact information published on their website. The City encourages residents to express their concerns about aviation-related noise to the appropriate agency as noted below.
