The Federal Emergency Management Agency (FEMA) issues maps that are used to regulate development projects in the floodplain and establish flood insurance rates. These maps are called Flood Insurance Rate Maps or FIRMs. The Village of Lisle Floodplain Map is a simplified look at the floodplains in Lisle. To review a detailed map of the floodplain, use the Village's Online Floodplain Map.
