The verdict

Kauai 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 17% below the Hawaii county mean. FEMA's separate National Risk Index places the county in the riskiest 16%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Kauai County is led by Riverine Flooding (about $47.7M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Kauai County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,495 claims and $47.7M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $31.9K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.

Start with the state benchmark: a Hawaii county averages 20.6 federal declaration records, while Kauai County has 17. The gap is 17% 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 84.4/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $60.9M in annualized losses). Social vulnerability reads Relatively Low and community resilience Very High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 6 years here.

How often does each hazard strike Kauai 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
Landslide Relatively Moderate roughly once every 6 years
Wildfire Relatively Moderate roughly once every 203 years
Riverine Flooding Relatively Moderate an average of 5.8 times per year
Lightning Relatively High an average of 79 times per year
Tsunami Relatively Moderate roughly once every 2 years
Hurricane Relatively Low roughly once every 10 years
Coastal Flooding Relatively Low roughly once every 4 years
Earthquake Very Low roughly once every 1,182 years
Drought Very Low 4.2 modeled event-days per year
Tornado Very Low roughly once every 119 years
Strong Wind Very Low roughly once every 150 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Kauai County's federal record, 29% 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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Kauai County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively Moderate), 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

Kauai County's closest FEMA peer: Kleberg County, TX

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