How to Determine if There are Public Drainage Facilities on Your Property
Flood Control Webcams
The San Diego County Flood Control District maintains several webcams at selected low water crossings throughout the county. You can view streaming video from the cameras to see the current state of the low water crossings.
The County currently maintains three webcams: the Quarry Road Dip on Spring Valley Creek in Spring Valley, the Sandia Creek Road Dip on the Santa Margarita River in Fallbrook, and the Country Club Road Dip on Escondido Creek in Harmony Grove.
Sandbags help to divert or redirect water, mud and debris from your property and help prevent soil erosion.
Free sand and sandbags are available to residents and business throughout San Diego County at the following locations:
Sandbags are also available at these retail vendors.
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.
Residents in recent wildfire burn areas should be aware of the increased potential for mud slides, debris flow, and severe flooding. The San Diego County Adverse Weather Map displays the 100-year Floodplain, recent fire burn areas, and weather alerts.
