April 2013 Post Flood Damage Surveys

Floodplain Management Services (FPMS)

On April 18th and 19th of 2013, severe storms produced a minimum of 5 to 6 inches of rainfall across northern Illinois with localized areas receiving as much as 9 inches of rain. Within the Chicago region, the extreme rainfall resulted in major flood stages, and in some cases, record stages on the Des Plaines River, North Branch of the Chicago River, DuPage River, Fox River, and their respective tributaries.  The impending flooding impacted numerous homes, businesses, and roadways.

On May 10th of 2013, the President declared a Federal Disaster (DR-4116) for 11 affected counties in Illinois.  Over the next several months, the declaration was expanded to include 49 counties in Illinois.  As of December 2013 the Federal Emergency Management Agency (FEMA) has approved more the $163 million in individual assistance and close to $19 million in public assistance to affected communities in Illinois.

In response to the severe flooding, the Chicago District is reaching out to affected residents and businesses to complete voluntary post flood damage surveys.  This result of the surveys will help the Corps better quantify and locate damages inflicted by the April 2013 flooding.  This data will further help the Corps better plan for and respond to future flood events, as well evaluate the benefits of potential Corps projects in the area.  The public surveying activities will target 6 counties around the greater Chicagoland area (Cook, DuPage, Kane, Lake, McHenry, and Will) and will focus on four key types of flood damage:

  • Residential damages
  • Basement backup damages
  • Non-residential/ business damages
  • Public (government) damages
