Are You Prepared?

Floods are the most common natural disaster in the United States. Floods cause more deaths and damage than any other severe weather event. In San Luis Obispo County, flooding most commonly occurs after periods of heavy rain and winter storms.  San Luis Obispo County is also at risk of a levee break or dam failure which can cause flooding in inundation areas.

Winter storms cause flooding, mudslides and other issues, such as power outages. Take small steps to prepare, survive, and be safe before, during, and after the storm. Help protect yourself and your family during the winter storm and flood season.

If you are in need of sandbags, you can purchase them here. Many locations around the county have sand available to residents.  Bringing your own sandbags and shovel is neccessary at most locations.
