Flooding

In a flood, emergency managers may ask you to either evacuate or shelter in place, depending on the area of impact, and most importantly, what will keep you and your family safest. To be prepared for either scenario, we recommend building both a go-bag and a stay box. Each should include the essential supplies you’ll need to stay safe and comfortable for 3–5 days. To prepare, you can also:

• Make a Plan. Know how you'll find and stay in touch with your family during a flood. Identify safe evacuation routes and places to go if you need to leave your home.
• Protect your home. Take steps to reduce flood damage:
  • Have a few sandbags  on hand before the winter months start.
  • Keep leaves and other yard waste out of gutters and storm drains.
  • Elevate utilities like electrical panels, heating systems, and appliances if possible.
  • Move vehicle to higher ground if possible.
  • Check your home’s flood risk using the Marin County Natural Hazards Map.
  • Consider obtaining flood insurance. A standard homeowner’s insurance policy does not cover flood damage. 

During disasters or life-threatening events, public safety agencies will issue emergency alerts. However, advance preparation and situational awareness are equally important. Take time to learn about the different types of warnings so you’ll know what actions to take.

1. If instructed to evacuate, do so immediately.
   1. Never drive around barricades.
   2. Avoid walking or driving through floodwater.
   3. Just six inches of moving water can knock you down, and one foot can sweep a vehicle away.
2. If instructed to shelter-in-place, stay indoors.
3. Move to higher ground or a higher floor to stay above rising floodwater. Do not become trapped in a basement or attic.
4. Stay calm. This will help you make safer choices for yourself and those around you. 

Check the Marin County Public Emergency Portal for local up-to-date information. 

• Pay attention to authorities for information and instructions.
• Return home only when told it is safe.
• Avoid floodwaters as they may be contaminated or electrically charged.
• Be aware of the risk of electrocution. Do not touch electrical equipment if it is wet or if you are standing in water.
