FEMA’s Flood Insurance Rate Maps set a property’s official flood zone. The City of Tampa’s Stormwater Division will look up a city address for free at (813) 274-3101, including its flood zone, base flood elevation and any elevation certificate on file, and it also keeps maps of localized street flooding that FEMA maps can miss.
Tampa is a Class 5 community in the National Flood Insurance Program’s Community Rating System, which takes 25 percent off flood premiums inside the high-risk zones and 10 percent outside them. Whatever the zone, Florida sellers of homes must tell the buyer, at or before signing the contract, about flood damage during their ownership and any flood insurance claims or FEMA help they received.
