The Federal Emergency Management Agency (FEMA) floodplain maps can be used to make a preliminary determination of the presence of a floodplain or floodway. You may also contact the Building & Engineering Division at 847-377-2600 to obtain a preliminary determination of the presence of a floodplain on a property.
