Floodplain Maps

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

DuPage Regulatory Flood Maps


The DuPage County Regulatory Flood Maps are used by the Village of Lisle and DuPage County when reviewing permit applications for new buildings, additions, decks, sheds, and grading. These maps are revised by the county on a regular basis and can vary from the FIRMs. These maps are large files and may load slowly.
