Los Angeles Mayor Karen Bass issued an executive order late Monday that her office said "will expedite the rebuilding of homes, businesses and communities" devastated by local wildfires.

"This order is the first step in clearing away red tape and bureaucracy to organize around urgency, common sense and compassion," Bass said in a statement. "We will do everything we can to get Angelenos back home."

The order was issued as dangerous wind conditions threatened additional homes across the Southern California area.

"This unprecedented natural disaster warrants an unprecedented response," Bass said.

A mayor's office press release said the executive order will coordinate debris removal from all impacted areas, expedite all building permit activity and take immediate action to make 1,400 units of housing available.

The order also set a one-week deadline for all city departments to list relief needed from state and federal authorities.
