Following a wildfire, soil conditions are known to produce rock and debris flows. These flows form rapidly, and can be particularly devastating during high-intensity rainfall. Additionally, areas that are not typically prone to flooding may now be at new risk due to higher than usual flows in nearby streams and creeks.
Residents should monitor weather forecasts from the National Weather Service (NWS) and local news agencies to ensure they are prepared for any possible rain and resulting mud and debris slides. In the Woolsey Fire area, there will remain a strong possibility of rockslides and mudslides, especially along PCH, canyon roads, and areas near Malibu Creek.
If rockslides or mudslides threaten public safety, a new evacuation order may be necessary. All residents are urged to comply with any such evacuation orders and evacuate the area as quickly as possible. Residents with limited connectivity who may not receive alerts should consider pre-evacuating. Protecting your life is most important.
In preparation of expected rain, staff is clearing storm drains throughout the City and will continually monitor rainfall and stream flow for potential rockslides and mudslides, particularly in the heavily burned areas.
Sandbags are available to Malibu residents at local Los Angeles County Fire Stations, while supplies last. Residents, with valid ID, may bag up to 25 sandbags per household. Sandbags, sand and shovels will be provided. Locations will also have a supply of pre-filled sandbags at Zuma Beach, PCH and Heathercliff, and PCH and Webb Way staring on Wednesday, November 21.
LA County Public Works teams are assessing property needs throughout the City and will leave documentation indicating whether the property requires more than 25 sandbags. That document can be presented at the fire station to allow residents to fill more than 25 bags.
For additional information about how to prepare for possible mudslides or rockslides, view the City's Storm Preparation Guidelines.
LA County Public Works published a handbook on how to properly place sandbags and debris blocking materials.
Motorists should allow extra time and be prepared for significant travel delays if road closures develop. Motorists should also be aware of rocks and other debris in the roads, particularly along PCH and canyon roads, and proceed with extreme caution.
