Frequently Asked Questions

Is this an official flood risk assessment?

No — this is a simplified, illustrative estimate only. For official flood zone determination (required for insurance and many mortgage decisions), consult FEMA's Flood Map Service Center or a licensed surveyor.

Why does elevation matter so much for flood risk?

Lower-elevation properties are more susceptible to both storm surge and inland flooding from heavy rainfall, since water naturally flows toward and accumulates in lower areas relative to surrounding terrain.

Do I need flood insurance if I'm not in a designated flood zone?

It's worth considering — a significant share of flood claims occur outside officially designated high-risk flood zones, since flooding can result from unusual weather events, drainage issues, or nearby development changes not reflected in older flood maps.
