Not sure if this will help, but I’m wondering if homes near brush or on hillsides in California should have sprinker systems installed on the adjacent hillsides and in brushy areas. I figure if a brush fire breaks out these systems can at least wet the nearby brush and slow down the spread of wildfire.
I remember a fire in Irvine a few years ago and the fire was along the toll road. I know there are sprinkler systems in the area and I wondered if turning them on could stop the spread of that wildfire.
