Full Breakdown
Palm Bay's floodplain management code sets a permit threshold for decks and patios built in coastal high hazard areas (Zone V) along the Indian River Lagoon and other flood-prone shoreline. A deck or patio thicker than 12 inches, or built with more fill than site drainage requires, cannot be approved unless a qualified registered design professional certifies no harmful diversion of floodwaters or wave runup and reflection. A deck or patio 12 inches thick or less, at natural grade, skips that extra analysis. Decks structurally attached to a building must also keep their lowest structural member at or above the design flood elevation.
Violations & Fines
Building an oversized coastal deck or patio without the required flood-engineering analysis is a Floodplain Administrator violation and can block final inspection or trigger a removal order.
