Charles M. Schulz - Sonoma County Airport2018 Complaint Summary

Charles M. Schulz – Sonoma County Airport 1

Charles M. Schulz - Sonoma County Airport (STS)

The Airport saw a steady decline in noise complaints throughout 2018. The Airport received 162 complaints

in 2018, showing a 69.5% decrease from the 531 complaints of 2017. This decline was a continuation from

the previous year with the departure of Allegiant Airlines. Of those 162 complaints, 150 were specific to the

Airport.

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 94% of the total. Related issues, such as flight paths, maneuvering and frequency accounted for

6%. Non-Airport-related complaints accounted for 7.4% 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 airport, number of total operations, and amount of complaints are listed below:
