The Santa Cruz County Board of Supervisors voted yesterday to have state firefighters use County fire engines in Bonny Doon rather than a state engine. The move is expected to save money and help response times to fires and other emergencies. The state engine, which is currently on Empire Grade Road, will be housed in Felton (during the rainy season) in an effort to avoid paying for a new garage in Bonny Doon, as well as avoid the costs of renting the state engine.
