Flood Information

Preparedness

Localized floods are typical after heavy periods of sustained rain. If you live in a low-lying area, near a creek, or floodplain you are likely aware of this danger.  Yet in San Luis Obispo County we also have the possibility of flooding after a levee break or dam failure.  Preparation is much the same for any type of flooding you are at risk for. 

Flood

 


Before a flood

  • Determine whether you live in a flood zone. Use the link at the bottom of this page to check!
  • Find out if you have flood insurance.
  • Avoid building in a floodplain unless you will be elevating your home.
  • Seal walls in basements with waterproofing compounds to avoid seepage.

If you suspect a flood

  • Move furniture and valuables to higher floors in your home.
  • Turn on the local radio or TV station for up to date news.
  • Be prepared to evacuate. Grab your disaster supply kit, pets, and valuables.


As you are evacuating

  • Do not drive through water of unknown depth. 1 foot of water can float a vehicle.
  • Do not drive through rushing water. 2 feet of water can wash away even large trucks and SUVs.
  • Avoid downed power lines.
  • Do not drive around barricades. Roads or bridges may be washed out.
