The Half Moon Bay Airport is located on the scenic Northern California coast about 20 miles south of San Francisco. It was constructed by the California State Highway Department for the U.S. Army in 1942. The Army turned the Airport over to the Navy following the end of WWII and the County acquired the Airport from the Navy in 1947. The Airport has served a variety of roles over the years and is currently an important business, transportation and emergency service asset to the community.

Half Moon Bay Airport provides a variety of emergency service and response functions including: Air-Ambulance and Medivac flights; law enforcement and homeland security patrols; Coast Guard sea-rescue operations; and use as a disaster relief staging site for the airlifting of emergency supplies in the event that roads are closed during a disaster or emergency.
