Full Breakdown
Chapter 113 requires all development in flood hazard areas mapped on the Miami-Dade Flood Insurance Study to meet Florida Building Code and ASCE 24 flood-resistant construction standards, administered by the city's floodplain administrator. The construction regulation board reviews permits and variance requests but is barred from ever approving a lowest floor, or dry-floodproofing level, below the base flood elevation shown on the FIRM. Critical facilities such as hospitals and fire or police stations face a higher bar: elevation or dry floodproofing to the 500-year flood elevation plus one foot. Detached accessory structures built below BFE need flood-resistant materials and utilities raised to BFE plus one foot.
Violations & Fines
Building without a required floodplain permit, or below the mandated elevation, is a violation under Sec. 113-8; the floodplain administrator can issue stop-work orders, and continuing work after one draws statutory penalties.
