FEMA flood zone rules in East Honolulu, HI — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Development in East Honolulu's FEMA-mapped flood zones falls under ROH Chapter 21A, which governs special flood hazard areas, flood fringe elevation standards, and flood variance procedures.
Sec. 21A-1.5 adopts the FEMA Flood Insurance Rate Maps identifying special flood hazard areas. Sec. 21A-1.8 requires new construction in the flood fringe to elevate to or above base flood elevation. Sec. 21A-1.12 governs flood variance standards. LUO Sec. 21-9.10 cross-references development in flood hazard areas. East Honolulu floodplains include portions of Hawaii Kai drainageways, Kuliouou Stream, and coastal areas subject to tsunami inundation. Compliance supports eligibility for the National Flood Insurance Program.
Building without proper elevation or a flood-compliant design, or ignoring flood hazard requirements, can result in stop-work orders, denial of certificates of occupancy, and insurance consequences.
