Full Breakdown
Lafayette City-Parish Consolidated Government's floodplain code requires new construction and substantial improvements to any residential structure in a mapped special flood hazard area to elevate the lowest floor -- including basement, garage, or carport -- at least 12 inches above the base flood elevation (BFE). Attached utilities like HVAC, plumbing, and electrical must also sit 12 inches above BFE. Nonresidential buildings get the same 12-inch elevation rule or can be floodproofed instead. The requirement applies inside the City of Lafayette and the unincorporated parish alike -- Broussard, Carencro, Duson, Scott, Youngsville, and Milton set their own rules.
Violations & Fines
Building below the 12-inch freeboard mark without a floodproofing certification is a misdemeanor punishable by up to $100 per day and 30 days in jail; each day of noncompliance is a separate violation.
