2015 Complaint Summary

Charles M. Schulz - Sonoma County Airport (STS)

The Runway Safety Improvement Project maintained Sonoma County Airport’s compliance with FAA standards and further enhanced operational safety in 2015. The Airport recorded a total of 229 complaints in 2015, which represents a 33% reduction from 2014, which had a total of 343 complaints. Of these 229 complaints, 200, or 87%, were Airport –related (as defined at the bottom of page 3 of this report).

Having weathered temporary shifts in air traffic during 2014 due to the 6-month closure of Runway 14- 32 (during which period many residents lodged complaints for the first time), the Airport enjoyed fewer complaints in 2015, especially early in the year. The Airport recorded 152 complaints from first and second time callers in 2015, compared to 193 in 2014. New callers still inquired if there were changes to the flight pattern, perhaps indicating lingering effects from the previous year’s closure. First and second time callers accounted for 66% of overall complaints in 2015.

The noise complaints were generated from all over Sonoma County, at various times of the day and night, primarily involving airline, corporate, and general aviation aircraft. A breakdown of Airport-related complaints shows that concerns about noise and low-flying craft account for the largest percentage, with a combined 73% of the total. Related issues, such as overflights and maneuvering, accounted for 27%. Non- Airport-related complaints accounted for 13% of the total.

The Airport contacted other airports in the larger Bay Area to assess how noise complaints as STS compare geographically. In total, the Airport collected data from seven area airports, which vary in size and number of operations. The airports, number of total operations, and number of complaints are listed below:
