As part of its storm preparation plan, the City continues to monitor 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 to prevent flooding and debris flows, and has pre-placed heavy equipment at areas sensitive to flooding and debris flows. Sheriffs Volunteers On Patrol (VOP) assist with patrolling City streets and reporting issues.

During storm events, flooding, mud and debris flows are a very real and dangerous threat to the communities affected by the Woolsey Fire. Due to an increased probability of mud and debris flows in these fire areas, it is important to plan and prepare. Prepare for lack of water, power and natural gas, non-functional traffic signals, and roads that may be impassable.

Mud and debris flows can have a devastating impact, including loss of life and home. Residents are urged to prepare for possible evacuations. Evacuation orders should not be taken lightly and are ordered because there is a threat to life and property. Evacuate early to reduce traffic congestion out of Malibu.

Due to potential storm-related power outages, it is possible that residents may not receive emergency alerts. Please monitor storm conditions on local news radio, and if possible, 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.

Road Hazards
Based on mud, debris, and other hazards, roads throughout the burn areas are subject to intermittent closures due to mud and debris flow. Use extreme caution as you drive through these areas. Watch for slippery road conditions and follow posted warnings and speed signs.

On the roads, be cautious of emergency, utility and work crews and vehicles. Approach all intersections with caution, traffic signals may be out due to storm-related power outages. Never drive into moving water. If you become isolated, seek the highest ground available and wait for help. If flooding traps you in your car, stay inside. If the water rises higher, wait on top of your car for assistance. Do not step into moving water around your car.

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.

Utilities
Know how to shut off utilities. Beware of water around electricity, including downed power lines, generators, electric appliances, and your home electrical system. There may be storm relate power outages. For current power outages, visit SCE outage center page at https://www.sce.com/outage-center.

Flood Insurance
