Flood Plain and Flood Insurance Information

Do you have a question on whether a property in the Village of Downers Grove is in a Floodplain or Localized Poor Drainage Area (LPDA)? Do you need FEMA flood insurance rate map information?

  • Flood plain and LPDA information can be found using the Parcel Navigator Map
  • General information regarding our stormwater program, flood plain, LPDAs, creeks and wetlands, and the National Flood Insurance Program (NFIP) can be found on the Stormwater page. 

Residents, builders, lenders, realtors and insurance agents are welcome to contact the Public Works Department for assistance with FEMA floodplain requirements and data. Please keep in mind that mortgage lenders make the official determination for flood insurance requirements. The Village also maintains elevation certificate records.

For more information, please call 630-434-5460 and ask for the Stormwater Administrator, or email
