Flood Zones
Chapter 17.88 of the Brookfield Municipal Code establishes the Floodplain District, regulating areas of special flood hazard identified as Zones A, AO, AH, A1-30, and AE on the FEMA Flood Insurance Rate Map (FIRM). Floodplain boundaries are based on the FEMA Flood Insurance Study for the City of Brookfield, Waukesha County, dated November 5, 2014. Permits are required for all development within the 100-year floodplain - including buildings, additions, remodeling, fences, raised gardens, fire pits, fill, and excavation. The ordinance distinguishes between the Floodway District (FW), where conveyance is required, and the Floodfringe District (FF). Alterations require FEMA and Wisconsin DNR review through the Letter of Map Change (LOMC) process.
