The Sonoma County Department of Public Infrastructure today announced plans to refurbish a section of runway pavement and replace a deteriorating culvert following an annual inspection and report issued by the Federal Aviation Administration. The FAA, which has oversight of safety and operations at the regional airfield, conducts annual audits at all active airports with airline service in the United States to ensure compliance with federal safety regulations and provides a checklist of required improvements.
