Full Breakdown
In Zones A1-30, AE and AH, Bryan's floodplain ordinance requires the lowest floor (including basement) of new construction and substantially improved residential structures, plus all mechanical equipment, to sit at least one foot above the FEMA base flood elevation. Manufactured homes face a stricter two-foot standard. Where no BFE data exists, the lowest floor must reach three feet above the highest adjacent grade, or two feet above the adjacent roadway crown. The floodplain administrator reviews all permits in special flood hazard areas for compliance before construction begins.
