Flood Risk Profile

Why Illinois Has High Water Damage Risk

Chicago's combined sewer system (storm + sewage share the same pipes) backs up into basements 20–30 times per year during heavy rain — making basement flooding the #1 property damage type in the state

  • Combined sewer overflow into basements
  • Lake Michigan storm surge on North Shore
  • Illinois/Kankakee River flooding
  • Spring snowmelt overwhelm
Winter Freeze Risk: Significant — Chicago averages 35 days below 20°F annually; Lake Michigan's wind chill can reach -40°F; exposed pipes in uninsulated crawlspaces freeze every winter
