California’s increasingly deadly and destructive wildfires have become so unpredictable that government officials should consider banning home construction in vulnerable areas, the state’s top firefighter says. Department of Forestry and Fire Protection Director Ken Pimlott will leave his job Friday after 30 years with the agency. In an interview with The Associated Press, he said government and citizens must act differently to protect lives and property from fires that now routinely threaten large populations. That may mean rethinking subdivisions in thickly forested mountainous areas or homes along Southern California canyons lined with tinder-dry chaparral. Yet Los Angeles County supervisors stung by California’s housing shortage approved a massive rural housing development Tuesday despite the fire danger.
