Coastal and Floodplain Construction Inspector's Practice Exam

Which flood zone is referred to as Zone V on flood hazard maps?

1. A low-risk area for flooding

2. An area subject to high-velocity wave action

3. An area with minimal rainfall

4. A dry creek bed

The correct answer is: An area subject to high-velocity wave action

Zone V on flood hazard maps signifies areas subject to high-velocity wave action, typically found along coastlines where the risk of flooding is exacerbated by storm surges and wave effects during severe weather events. This designation is crucial for understanding potential flood risks and implementing appropriate construction standards to mitigate damage. In Zone V, buildings must be elevated above the base flood level and adhere to stringent design considerations because of the dynamic forces that waves can exert. This preparation protects structures and occupants from the destructive impacts of flooding, which are particularly pronounced in areas susceptible to such powerful wave action. The other options refer to conditions that do not align with the characteristics of Zone V. Low-risk flood areas and minimal rainfall pertain to zones that may have reduced or negligible flooding risk, while a dry creek bed does not represent a floodplain area that would be categorized as Zone V. Understanding these classifications is essential for effective land use planning and floodplain management, ultimately ensuring safety and resilience in coastal environments.
