Coastal and Floodplain Construction Inspector's Practice Exam

What is the maximum height for the bottom of the lowest horizontal member of the deck in relation to the bottom of the building’s lowest horizontal member?

1. 5 feet

2. 6 feet

3. 8 feet

4. 10 feet

The correct answer is: 8 feet

The maximum height for the bottom of the lowest horizontal member of the deck, in relation to the bottom of the building’s lowest horizontal member, is an important consideration when designing structures in flood-prone areas. This requirement is set to ensure that the deck remains adequately elevated above potential flooding, preventing water from causing structural damage. The correct choice highlights that the bottom of the lowest horizontal member of the deck must be no more than 8 feet above the bottom of the building's lowest horizontal member. This height provides a balance between structural safety and practicality, ensuring that decks do not exceed the recommended elevation which could make them less accessible or usable. By maintaining this specific height, builders can help prevent water intrusion during flood events, which is critical for the longevity and safety of both the deck and the associated building. It aligns with best practices in floodplain management, emphasizing the significance of complying with regulations that protect properties from flood risks.
