Don’t know your Flood Zone?
To find out if a property is in a Special Flood Hazard you can search by address or parcel with the SJC Flood Zone Viewer.
You can also find a wealth of information in the SJC iMap including Evacuation Routes, Flood Hazards, Storm Surge Zones, Costal Construction Control Line, Wind Borne Debris Areas and much more.
For an official floodplain determination, questions about CRS and/or file copies of Elevation Certificates, please contact our Floodplain Management Team.
Floodplain Development Permit Requirements
Any development in the floodplain requires a construction permit. If you suspect that illegal floodplain development is occurring call the St. Johns County Code Enforcement at (904) 827-6800.
Local Flood Hazards
The Local Flood Hazard Flooding in St. Johns County is primarily caused by heavy rainfall in short periods of time, commonly associated with thunderstorms, and from seasonal high tides. The greatest flood threats come from tidal surges that accompany coastal storms, tropical storms and hurricanes. For local precipitation data reports, visit the St. Johns County Water Management District.
For many people, their home and its contents represent their greatest investment. Property losses due to flooding are not covered under most standard homeowners’ insurance policies. You can protect your home and its contents with flood insurance through the National Flood Insurance Program (NFIP).
The NFIP is a federal program established by Congress in 1968, which enables property owners to buy flood insurance at reasonable rates in participating
communities. In return, participating communities conduct flood management measures designed to protect life and property from future flooding.
The NFIP is administered by the Federal Emergency Management Agency (FEMA) through its Federal Insurance Administration (FIA). St. Johns County has participated in the NFIP since 1973.
To find out more about flood insurance for your property and its contents, contact your insurance agent. There is a 30-day waiting period before a flood insurance policy takes effect, so don’t wait until a storm threatens before purchasing the flood insurance you need.
Drainage System Maintenance
A community can lose a portion of its drainage system carrying or storage capacity due to dumping, debris, soil erosion and sedimentation, and overgrowth of vegetation. When this happens, flooding occurs more frequently and reaches higher elevations, subjecting properties otherwise protected to unnecessary risk of damage. Keep grass clippings and other debris out of storm water drainage systems to prevent clogging and loss of storm water storage and treatment capacity.
If you experience any localized drainage problems, including illegal stream dumping, please notify the County Road and Bridge Department at (904) 209-0246, so that the problem can be corrected.
