Coastal and Floodplain Construction Inspector's Practice Exam

What is the maximum allowable height for the deck in relation to BFE in V zones?

1. 2 feet

2. 3 feet

3. 4 feet

4. No maximum height

The correct answer is: 3 feet

In coastal flood zones, particularly in V zones which are areas susceptible to high-velocity floodwaters, the design and construction of structures must comply with specific regulations to ensure safety and durability. The maximum allowable height for the deck above Base Flood Elevation (BFE) is crucial for minimizing risks associated with flooding. The correct answer is that the maximum allowable height for a deck in relation to BFE in V zones is 3 feet. This height restriction is designed to reduce the potential for damage from debris and strong currents during flood events, as well as to prevent the deck from becoming a floating obstacle that could impact the structural integrity of the building or the safety of occupants. By limiting the height to 3 feet, regulations maintain a balance between functionality of outdoor spaces and the need for heightened safety in flood-prone areas. Structures built too high could also pose problems for proper water drainage and lead to increased risk of structural failure during extreme weather. This maximum height can be seen as an integral part of the overall floodplain management strategy to enhance resilience against natural hazards while encouraging responsible construction practices.
