Kankakee County ranks as relatively moderate risk

Kankakee County's composite risk score of 88.23 exceeds Illinois's state average of 54.46 by 62%, earning a relatively moderate risk rating. The county's primary exposure stems from exceptionally high flood (92.46) and tornado (85.91) risks, making it one of the state's more vulnerable areas.

Second-highest risk among Illinois counties

At 88.23, Kankakee County ranks among the very highest-risk counties in Illinois, exceeded only by a handful of counties including Kane County. The county's flood and tornado scores are among the most severe statewide.

Riskier than most surrounding counties

Kankakee County's 88.23 score substantially exceeds Kendall County (80.25) to the west and Johnson County (51.08) to the south. Only Kane County to the north approaches similar risk levels in the region.

Floods and tornadoes create urgent hazards

Kankakee County faces exceptional flood risk of 92.46 and tornado risk of 85.91, both among the highest in Illinois. Earthquake risk of 80.47 rounds out the county's multi-hazard profile, though wildfire exposure remains manageable at 20.26.

Flood and storm insurance are essential

Kankakee County residents must maintain active flood insurance and comprehensive homeowners coverage for tornado damage—these are non-negotiable given the county's extreme exposure. Elevating utilities, installing storm shutters, and identifying a safe room are practical protective measures for this high-risk location.

Risk Verdict

At the 88th percentile nationally, Kankakee County sits in the upper half of U.S. counties for natural disaster exposure. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Kankakee County residents.

Hazard Breakdown

Flood risk is Kankakee County's dominant natural hazard, ranked at the 92th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 86th percentile nationally. Additional tracked hazards include earthquake (80th percentile), hurricane (27th percentile), wildfire (20th percentile).

Preparedness Context

At the 92th percentile nationally for flood risk, Kankakee County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Alongside flooding, tornado exposure at the 86th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Kankakee County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

The Illinois county average is 33.8 composite points below Kankakee County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
