Firefighters quickly knocked down a small brush fire in eastern Ventura County which burned close to some homes. The fire was discovered just after 4:30 Tuesday afternoon in a rugged canyon behind Arroyo Vista Street, north of Highway 101 in Newbury Park. The fire burned up to the backyards of some homes, but more than 50 Ventura County firefighters aided by helicopter water drops stopped the flames. The estimate of the size of the blaze was downgraded to about two acres. No structures were damaged. No evacuations were ordered, although some people who lived in homes on the ridgeline above the canyon were ordered to shelter in place. The cause of the fire is under investigation.
