Answer :
Final answer:
Zone V is the FIRM zone where wave heights can exceed 3 feet, particularly in coastal areas during storm surges. The correct option is b.
Explanation:
The question 'What FIRM zone has wave heights greater than 3 feet?' refers to Flood Insurance Rate Map (FIRM) zones used in the context of the National Flood Insurance Program in the United States. Among the options provided: Zone A is the flood insurance rate zone that corresponds to the 100-year floodplain; Zone V is the flood insurance rate zone that includes coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves; Zone B, now referred to as Zone X, is the area of moderate flood hazard; and Zone X is the area of minimal flood hazard. Therefore, the correct answer would be Zone V, as it is a zone specifically characterized by coastal areas with wave heights that can exceed 3 feet, especially during storm surges.
