Flooding can happen in many places. Even if your home is not in a high-risk flood area, the places you visit might be. Know what to do before, during and after one occurs.

Before a Flood


What causes a flood? 

Heavy rainfall, long periods of rain, rapid snowmelt, clogged drains, dam breakage, levee failure, overflowing bodies of water (i.e. streams, rivers, and lakes). 

They can be slow or fast. They can injure people and animals, cause loss of utilities, disrupt transportation, create land movement, and damage property.

  • Monitor the news and stay aware of weather conditions. If you live near a lake, river, or creek, check local river gauges. If you live on a slope and it has been raining a lot, be ready for possible land movement
  • Evacuate the area if you think a flood may occur or if you are told to do so by local authorities. It’s critical that you know how to stay informed.
  • Stay out of flood waters, off bridges with fast-moving water, and away from power lines or objects touching power lines.
  • Bring in or secure outdoor items, such as lawn furniture, grills, and trash cans.
  • Turn off electrical power when there is standing water or fallen power lines, or before you evacuate. Turn off gas and water supplies before you evacuate.

If You Need Shelter

During a disaster, the Red Cross and the County help people who are displaced from their homes. They set up shelters (or “Disaster Resources Centers”) to connect people with services and provide a place to sleep for the first few days. Contact 211info to find resources near you.

After a Flood


Preventing Injury

Do not walk or swim through floodwater. It can be very unsafe. It may contain sharp objects, chemicals, human waste, animal waste, power lines, or other dangerous items. 

Preventing Illness

  • Do not drink, cook with, clean with, or bathe in flood water - it could make you very sick. 
  • Local officials will provide information about the safety of your water. Stay informed and sign up to receive alerts. 
  • Know how to treat water and handle food when the power goes out. 
  • Wash your hands with soap and clean water every time you touch flood water and before every meal. 
  • Do not allow children or pets to play in floodwater areas or play with toys that have been contaminated.
