How is flood risk determined?
FEMA conducts a Flood Insurance Study (FIS) of a region to identify the community’s risk levels. The FIS includes statistical data for river flow, storm tides, rainfall, topographic surveys, as well as hydrologic and hydraulic analyses. After examining the FIS data, FEMA creates a map delineating the different areas of flood risk.

Enter your property’s location in the FloodSmart.gov risk assessment tool. My home is in a floodplain. Am I at high risk for flooding? Yes. Buildings in floodplains, or Special Flood Hazard Areas (SFHAs), are at high risk for flood damage. Some floodplains experience frequent flooding, while others are affected only when there is a severe storm. As a homeowner in a floodplain, it’s not so much a question of if a flood will damage your property as when. That’s why the law requires you to have flood insurance. Did you know that an SFHA home has a 26% chance of being flooded over a 30-year period, as compared to
Flood risk is determined by use of all available information for each community. Historical flood data, rainfall and river-flow data, topography, wind velocity, tidal surge, flood control measures, development (existing and planned), community maps, and other data are all elements used in determining flood risk. 4. How does the County participate in the National Flood Insurance Program? When the County joined the NFIP, it adopted and began to enforce minimum floodplain management standards. FEMA worked closely with the State and the County to identify flood hazard areas, flooding risk and to establish minimum floodplain management standards. The floodplain management standards are designed to prevent new development from increasing the flood threat and to protect new and existing buildings from anticipated flood events. 5. What is a Flood Insurance Rate Map? (FIRM) A FIRM is a map on which FEMA has delineated both the areas of special flood hazards and the risk premium zones applicable
