Flooding is a temporary overflow of water onto land that is normally dry. Floods are the most common natural disaster in the United States. Failing to evacuate flooded areas or entering flood waters can lead to injury or death.

Floods may:

  • Result from rain, snow, coastal storms, storm surges and overflows of dams and other water systems.
  • Develop slowly or quickly. Flash floods can come with no warning.
  • Cause outages, disrupt transportation, damage buildings and create landslides.


  • Sign up for AlertSCC by going to to receive critical information from the County when flooding is going to occur in your area. Your information is safe and you may opt-out at any time.

These sites are stocked with either filled sandbags or sand and empty bags for self-filling and require you to bring your own shovel. Please bring assistance for loading heavy bags, if necessary. 



Keep creeks clean and flowing.  Trash and debris in creeks can block the flow of water and cause flooding. Help us keep creeks flowing by reporting downed trees, blockages or illegal dumping.
