The Contra Costa RACES Mission is to train, organize and deploy radio amateurs in support of agencies and organizations in Contra Costa County.

Communications system failures can be caused by a natural disaster, human caused disaster, or even a terrorist attack. RACES fills an important need during a critical communications system failure or overload that puts the public at risk.
