Flood Safety Information

Floodplain Information

The Repetitive Flood Loss Area Analysis for Prince William County looks at the properties in low-lying areas along inland waterways, as well as the coastal area along the Potomac River. Mitigation - or actions taken to reduce risk - to address these repetitive loss properties will ultimately be instrumental in reducing the overall costs to individual homeowners as well as the National Flood Insurance Program.

The Department of Public Works Environmental Services Division maintains elevation certificates for new and substantially improved buildings. Copies of elevation certificates can be accessed online in the interactive floodplain viewer.

We have made Flood Insurance Rate Maps (FIRMs) interactive for Prince William County in our interactive floodplain viewer. You may also print a PDF of your specific FIRM.

Purchase Flood Insurance. Homeowners and business multi-peril insurance policies do not cover losses from floods. Flood insurance policies must be purchased as a separate policy. Properties in Flood Zone A, AE, and VE are required to carry flood insurance if they have a federally backed mortgage. For properties in Flood Zone X, it is highly recommended to carry flood insurance as floods do not respect Zone X boundaries. More information is available on topics from flood insurance advice, to property protection, the hazard mitigation plan, flood safety.  Emergency Preparedness information and real-time flood gauges are available in the links below.
