These FIRMs are used in identifying whether a land or building is in flood zone and, if so, which of the different flood zones are in effect.

On the new maps in Palm Beach County, about 5,000 properties have moved to a high-risk flood zone, also considered a "special flood hazard area," from a low- or medium-risk flood zone.
