FEMA flood zone rules in Mililani Mauka, HI — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Most Mililani Mauka parcels sit on elevated terrain outside special flood hazard areas, but ROH Chapter 21A still governs any properties mapped within FEMA flood zones.
Chapter 21A regulates floodplain development. Key sections include 21A-1.5 adopting FEMA FIRMs for special flood hazard areas, 21A-1.8 requiring elevation to or above base flood elevation for flood fringe properties, and 21A-1.12 establishing flood variance standards. LUO Sec. 21-9.10 cross-references development in flood hazard areas. Much of Mililani Mauka sits on Zone X higher ground, but drainage swales and stream corridors can carry mapped flood zones. Residents near streams or designated drainage features should check the FIRM and follow elevation, flood-proofing, and variance procedures if their parcel is mapped as special flood hazard area.
Building below base flood elevation or ignoring mapped flood hazards in drainage corridors can lead to permit problems, insurance issues, and required retrofits.
