Utilities 'significantly damaged'
The power, transportation and sewer systems have been "significantly damaged" in the fires, Los Angeles County Public Works Director Mark Pestrella said during the briefing, as they focus on utility restoration.
There is also a "tremendous amount of debris" that needs to be cleared, he said, warning that some debris may be hazardous and toxic.
He said the reservoirs are full and "continue to be ready and at the disposal of our firefighting friends," though the municipal water system "continues to suffer poor water quality" due to the ash and debris.
"I would just say, with all caution, anyone who's remained behind, if there is any residence in your area that is burned to the ground and you are still there, you should just go ahead and boil water," he said.
