When siting the foundation of a building in two different flood insurance zones, design and regulatory
requirements of the most restrictive zone apply. For example, even though the majority of the foundation of
the building illustrated in Figure 4-7 is located in Zone A, Zone V requirements would apply to the entire
building.
Regulatory controls do not necessarily prevent imprudent siting of coastal buildings. Figure 4-8 shows flood
and debris damage to new construction sited in Zone A that could have been avoided had the site been
designated a Coastal A Zone, and had the structure been elevated on an open foundation. Because there
are situations where minimum requirements do not address site-specific hazards, prospective buyers should
