Flood Zones: Burlington vs Mount Pleasant

Burlington regulates floodplain development through Chapter 119 (Floodplains) of the City Code, adopted by Ordinance No. 1942(19) on March 6, 2012. Chapter 119 establishes three districts: the FW Floodway District, the FFO Floodfringe Overlay District, and the GFP General Floodplain District. Boundaries are based on the Supplementary Floodland Zoning Map dated April 7, 1982 (and amendments) and FEMA Flood Insurance Rate Maps for the City of Burlington (Racine and Walworth Counties). The chapter is adopted under Wis. Stat. Sec. 87.30 and Wis. Admin. Code Ch. NR 116, and Burlington participates in the FEMA National Flood Insurance Program.

Division 90-490 of the Mount Pleasant Code of Ordinances is the 'Floodplain Zoning Ordinance for the Village of Mount Pleasant, Wisconsin,' adopted by Ordinance No. 19-2020 effective June 8, 2020 and amended July 24, 2023 and September 25, 2023. The ordinance is adopted under Wis. Stat. Sec. 61.35, Sec. 62.23, and Sec. 87.30 (statutory floodplain zoning) and is designed to meet Wis. Admin. Code Ch. NR 116 and 44 CFR Parts 59-72. Division 90-490 regulates all areas of special flood hazard identified as Zones A, AO, AH, A1-30, AE, VE, V1-30, or V on the FEMA Flood Insurance Rate Map for Racine County. The ordinance establishes the Floodway District (FW), the Floodfringe District (FF) within AE Zones, and the Coastal Floodplain District (CFD) within V, V1-30, and VE Zones along Lake Michigan, with separate provisions in Article VIII for nonconforming uses. The Pike River and Sorensen Creek are principal regulated waterways; the Lower Pike River is also subject to a 150-foot shoreland setback under Division 90-495.
