The Sonoma Air Attack Base was established in 1964 and is located at the northeast corner of the Sonoma County Airport, north of Santa Rosa.
Sonoma responds to an average of 300 calls per year. Staff at the base consists of one battalion chief, one fire captain, one fire apparatus engineer, and six firefighters. The complement of aircraft located at Sonoma includes one OV-10 Bronco and two S-2T airtankers.
On average, the base pumps about 300,000 gallons of retardant a year. With the base’s pumps, four loading pits and equipment, Sonoma has a possible peak output of 120,000 gallons of retardant each day.
The base’s immediate response area covers 4,000 square miles and includes Marin County and portions of the CDF Sonoma-Lake-Napa, Santa Clara, San Mateo-Santa Cruz, and Mendocino Units.
