Protecting Your Property
Sandbags help to divert or redirect water, mud and debris from your property and help prevent soil erosion
For more information on flood debris and erosion control, view the Homeowner’s Guide for Flood, Debris, and Erosion Control.
Sandbags can help protect your property from major damage, but sandbags will not seal out water, which is why it is important to make sure your property is financially covered.
Standard homeowners insurance does not cover flooding. It is important to have protection from the floods associated with heavy rains here in San Diego County. The National Flood Insurance Program (NFIP) is available to property owners to financially protect themselves.
Understanding Your Flood Risk
FEMA’s Flood Map Service Center is the official public source for flood hazard information. There, you can find official flood maps and other resources to get a better understanding of your flood risk.
