FEMA flood zone rules in Pearl City, HI — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Development in Pearl City's FEMA-mapped flood zones must comply with ROH Chapter 21A, which governs special flood hazard areas, elevation standards, and flood variance procedures.
Sec. 21A-1.5 adopts FEMA Flood Insurance Rate Maps identifying special flood hazard areas. Sec. 21A-1.8 requires flood fringe elevation to or above base flood elevation. Sec. 21A-1.12 governs flood variance standards. LUO Sec. 21-9.10 also cross-references flood hazard development. Pearl City areas near Waiawa Stream, Waimano Stream, and coastal reaches of Pearl Harbor have floodplain designations. Elevation, flood openings for enclosures, and flood-resistant materials may be required. Following Chapter 21A supports community eligibility for the National Flood Insurance Program.
Non-compliant construction in flood hazard areas can result in stop-work orders, denial of certificates of occupancy, and flood insurance impacts.
