Chicago FAQ
Is my Chicago property in a flood zone?
Check FEMA's Flood Insurance Rate Maps (FIRMs) for your address. Areas along the Chicago River, North Shore Channel, and some lakefront sections are in Special Flood Hazard Areas requiring flood insurance and elevated construction.
Do I need flood insurance in Chicago?
If your property is in a FEMA-designated Special Flood Hazard Area and you have a federally backed mortgage, flood insurance is required. It is recommended for all properties near waterways regardless of zone designation.
Skokie FAQ
Is my Skokie property in a flood zone?
Most of Skokie is not in a mapped FEMA Special Flood Hazard Area, but portions near the North Shore Channel are. Check the FEMA Flood Map Service Center by address. Urban flooding from sewer backups can affect properties outside mapped zones.
Do I need flood insurance?
Mortgages on properties in SFHAs typically require NFIP flood insurance. Properties outside SFHAs can still buy preferred-risk NFIP policies, and given Skokie's history of urban flooding, coverage is worth considering even outside mapped zones.
What can I do about basement flooding?
Skokie's overhead sewer conversion program and flood control improvements help many properties. Install a backwater valve, overhead sewer conversion, and sump pump with battery backup. Contact Public Works at (847) 933-8427 about resident assistance programs.
