Frequently asked questions
How do I find out if I'm in a flood zone?▾
Enter your zip code above. GridPrepped uses FEMA National Risk Index data to show your area's flood hazard rating. For property-level Special Flood Hazard Area (SFHA) lookup, visit FEMA's NFHL viewer at msc.fema.gov.
Does a low flood risk mean I don't need flood insurance?▾
No. More than 25% of flood claims come from areas outside high-risk zones. Standard homeowners insurance does not cover flooding. Consider NFIP or private flood insurance regardless of zone.
What's the difference between a 100-year and 500-year flood?▾
A '100-year flood' has a 1% chance of occurring in any given year — not once per century. A '500-year flood' has a 0.2% annual chance. Over a 30-year mortgage, the 100-year flood has a 26% cumulative chance.
