Full Breakdown
Independence's Floodplain Management Ordinance sets the local freeboard standard: new construction or substantial improvement of a residential structure, including manufactured homes, in a mapped special flood hazard area must have its lowest floor, including any basement, elevated to one foot above the base flood elevation shown on the FEMA Flood Insurance Rate Map. Mechanical and HVAC equipment must be elevated or floodproofed to that same level. A Missouri-licensed land surveyor, engineer, or architect must certify the lowest-floor elevation, and the Municipal Services Director, as floodplain administrator, keeps that certification on file before issuing a floodplain development permit.
Violations & Fines
Building without a floodplain development permit, or below the required elevation, is a misdemeanor punishable by a fine up to $500 per day the violation continues.
