Attention Malibu Park Neighborhood and Surrounding Properties:
Due to the amount of localized mud and debris flows that have occurred during the December and January storms, privately owned, manmade drainage channels, creeks, and other stormwater systems may have been impacted. These systems typically require yearly maintenance and clearance of mud and debris by property owners. It is critical for property owners to maintain stormwater drainage to minimize negative impacts to the surrounding community. Please reach out to your neighbors to make sure private stormwater systems are cleared before, during, and after storms.

- See detailed maps of the areas in Malibu that are at risk for post-fire flooding, mudslides and debris flows on the City's Flood Vulnerability Maps page - https://www.malibucity.org/924/Flood-Vulnerability-Maps
- As part of its storm preparation plan, the City monitors storm conditions, and crews are patrolling and clearing roads of rocks and debris, clearing storm drains and culverts to prevent flooding, placing temporarily concrete k-rails as needed to prevent flooding and debris flows, and has heavy equipment staged at areas sensitive to flooding and debris flows. Sheriff’s Volunteers on Patrol (VOP) will assist with patrolling City streets and reporting issues.
- During storm events, flooding, mud and debris flows are a very real and dangerous threat, especially in the Woolsey Fire burn area. Prepare, water or gas outages, non-functional traffic signals, hazardous driving conditions and roads that may be impassable.
- Prepare for possible evacuations. Evacuation orders should not be taken lightly and are ordered because there is a threat to life and property.
- People with mobility issues or large animals, should consider evacuating early.
- Due to potential storm-related power outages, it is possible that residents may not receive emergency alerts. Please monitor storm conditions on local news and the National Weather Service at https://www.weather.gov/lox. If heavy rain persists, do not wait for evacuation orders - leave early.

Stay away from flood control channels, catch basins, canyons and natural waterways, which are susceptible to flooding during periods of heavy rain. Check on your neighbors, particularly those who are elderly or live alone. People who live on gated properties should leave gates open to prevent mud and debris from locking them in, and to ensure access for emergency responders. Move trashcans and cars off the street to help prevent flooding.
If you see someone who has been swept into moving water, do not enter the water and attempt a rescue. Call 911 for emergency rescue personnel and, if possible, throw them a flotation device.
