Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Kendall County is led by Riverine Flooding (about $33.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Cold Wave carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Kendall County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 174 paid claims, totaling $3.1M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $18.1K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Kendall County's 13 federal records stand 1% above the Illinois county mean of 12.9. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 80.2/100 (Relatively Low). Expected Annual Loss is rated Relatively Moderate (roughly $74.8M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Cold Wave stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 5.2 times per year here, based on 98 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 13 entries for Kendall County, including 7 Major Disaster records, 1% above the Illinois county mean. Across the 47-year span, that works out to 0.3 declarations a year. Snowstorm leads the file with 4 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Kendall County?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Hazard NRI Risk Rating Recurrence
Cold Wave Relatively High an average of 5.2 times per year
Tornado Relatively Moderate roughly once every 4 years
Strong Wind Relatively High an average of 6.3 times per year
Riverine Flooding Relatively Moderate an average of 1 time per year
Earthquake Relatively Low roughly once every 707 years
Heat Wave Relatively Low 3.5 modeled event-days per year
Winter Weather Relatively Low an average of 14 times per year
Drought Relatively Low 6.8 modeled event-days per year
Ice Storm Relatively Low roughly once every 1 years
Lightning Relatively Low an average of 44 times per year
Landslide Very Low roughly once every 19 years
Hail Very Low an average of 4.4 times per year
Wildfire Very Low roughly once every 10,968 years
Hurricane Very Low roughly once every 100 years

What Snowstorm declarations mean here

Snowstorm is the most frequent declaration type on Kendall County's record, 31% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.

The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Cold Wave

Cold Wave measures exposure to extreme cold rather than to snow. Its harm is concentrated in health effects, burst infrastructure and energy demand spikes, and it falls hardest where the building stock and the grid were not built with sustained cold in mind.

For Kendall County the two measures on this page point the same way: Cold Wave is the county's highest-rated modeled hazard (Relatively High), and Snowstorm declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data-matched county comparisons

Kendall County's closest FEMA peer: Okeechobee County, FL

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Kendall County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.

Kendall County has 174 National Flood Insurance Program (NFIP) claims totaling $3.1M in payments, with an average of $18.1K per claim.
Does FEMA's top risk-rated hazard match the highest Expected Annual Loss in Kendall County?
No. In Kendall County, Cold Wave has the highest National Risk Index rating (Relatively High), while Riverine Flooding leads Expected Annual Loss at about $33.7M. FEMA's risk score and dollar-loss model use different inputs, so the leaders often differ.
What was the worst year for disasters in Kendall County?
The most active year for disaster declarations in Kendall County was 2020, with 2 declarations. The county has FEMA disaster data spanning 1973 to 2020.
What is the FEMA National Risk Index score for Kendall County?
According to the FEMA National Risk Index, Kendall County, Illinois has an overall risk score of 80.2 out of 100 (Relatively Low). On social vulnerability the county rates Very Low; on community resilience, Very High. The Expected Annual Loss (EAL) score is Relatively Moderate, representing $74.8M in annualized losses.
Which natural hazard poses the greatest risk to Kendall County?
Based on FEMA NRI data, the highest-risk natural hazard in Kendall County is Cold Wave (risk rating: Relatively High). Other significant hazards include Tornado (Relatively Moderate) and Strong Wind (Relatively High). FEMA's modeled event frequency puts cold wave here at an average of 5.2 times per year, drawn from 98 historical events on record. The underlying methodology weighs historical event frequency against exposed assets and community vulnerability.
Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

What this means for Kendall County

Kendall County, IL has 13 federal declaration records, 1% more than the Illinois county mean of 13; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 7 of 13 records; the category describes past federal action, not the next likely hazard. Illinois overview
  • The state benchmark and national rank point the same way: this count tops the Illinois mean and the totals for 17% of 3,266 U.S. counties. Most-disaster rankings
  • Use the data guide to separate this mid-volume insurance-claims file from declaration counts and modeled NRI risk. Disaster-data guide

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
