The verdict

Kent County has a nationally busy FEMA history: 17 declarations, more than 32% of counties in this registry. But the state comparison tempers that reading: the total is 6% below the Delaware county mean. FEMA's separate National Risk Index places the county in the riskiest 15%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Kent County is led by Riverine Flooding (about $23.5M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), 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 Kent County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 375 paid claims, totaling $3.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.5K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Delaware county averages 18.0 federal declaration records, while Kent County has 17. The gap is 6% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 84.5/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $55.8M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively 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 roughly once every 1 years here, based on 15 historical events on record.

How often does each hazard strike Kent 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 roughly once every 1 years
Winter Weather Relatively High an average of 7.8 times per year
Hurricane Relatively Moderate roughly once every 9 years
Heat Wave Relatively Moderate 5.2 modeled event-days per year
Drought Relatively Moderate 5.5 modeled event-days per year
Riverine Flooding Relatively Moderate an average of 1.4 times per year
Earthquake Relatively Low roughly once every 728 years
Lightning Relatively Moderate an average of 34 times per year
Coastal Flooding Relatively Moderate an average of 3.7 times per year
Tornado Relatively Moderate roughly once every 3 years
Ice Storm Relatively Moderate roughly once every 2 years
Wildfire Relatively Low roughly once every 1,176 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Kent County's federal record, 41% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

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.

Worth noting for Kent County: the model and the federal record do NOT point at the same hazard. Cold Wave carries the highest modeled rating (Relatively High), while the county's declaration history is led by Hurricane. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

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

Kent County's closest FEMA peer: Henderson County, TX

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Kent 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.

How many flood insurance claims has Kent County filed?
Kent County has 375 National Flood Insurance Program (NFIP) claims totaling $3.6M in payments, with an average of $9.5K per claim.
Does FEMA's top risk-rated hazard match the highest Expected Annual Loss in Kent County?
No. In Kent County, Cold Wave has the highest National Risk Index rating (Relatively High), while Riverine Flooding leads Expected Annual Loss at about $23.5M. FEMA's risk score and dollar-loss model use different inputs, so the leaders often differ.
What was the worst year for disasters in Kent County?

What is the FEMA National Risk Index score for Kent County?
According to the FEMA National Risk Index, Kent County, Delaware has an overall risk score of 84.5 out of 100 (Relatively Moderate). On social vulnerability the county rates Relatively Low; on community resilience, Relatively High. The Expected Annual Loss (EAL) score is Relatively Moderate, representing $55.8M in annualized losses.
Which natural hazard poses the greatest risk to Kent County?
FEMA's NRI data points to Kent County as of the latest release is Cold Wave (risk rating: Relatively High). Other significant hazards include Winter Weather (Relatively High) and Hurricane (Relatively Moderate). FEMA's modeled event frequency puts cold wave here at roughly once every 1 years, drawn from 15 historical events on record. The underlying methodology weighs historical event frequency against exposed assets and community vulnerability.
