Radio Amateur Civil Emergency Services (RACES)

The Radio Amateur Civil Emergency Services (RACES) program was founded in 1952. The RACES program is a volunteer group that provides communications support to the Office of Emergency Services during times of disaster. The members of the Sheriff's RACES Program are all licensed amateur radio operators who volunteer their time and service to the support of the Sheriff.

As part of their emergency planning, RACES members play an active role in preparing emergency communications support for all of the Cities within Contra Costa County. By coordinating their activities throughout the county, the members of the group are able to plan a coordinated and complete communications plan. No matter the type of emergency, the members of the RACES program will be there to provide communications support.
