Federal geologists have released new research to identify potential flash flooding and debris flows in areas where hillsides were stripped bare by the Hill and Woolsey brush fires.
The United States Geological Survey maps show the likelihood of debris flow generation, and estimates of flow magnitude.
The 96,000 acre blaze was fully contained last Wednesday. It destroyed more than 1600 structures. The maps show elevated flooding and debris flow issues in parts of the Conejo Valley, but the highest risk spots are in Los Angeles County, in the Malibu area.
