Full Breakdown
Kansas City designates the building official as floodplain administrator under Sec. 28-32. Before any development in a numbered or unnumbered A, AE, AO, or AH flood zone, owners must file a written floodplain development permit application describing the work, its fair market value, and whether it sits in the floodway or flood fringe (Sec. 28-34). New or substantially improved residential structures must have the lowest floor, including the basement, elevated at least one foot above the base flood elevation, with elevation certified by a Missouri-licensed surveyor, engineer, or architect (Sec. 28-52(1)).
Violations & Fines
Building without a floodplain permit is an ordinance violation carrying a fine up to $1,000 plus costs; each day the violation continues is a separate offense, and the site is presumed non-compliant until permit records are produced.
