The verdict

Kitsap County has a nationally busy FEMA history: 16 declarations, more than 27% of counties in this registry. But the state comparison tempers that reading: the total is 36% below the Washington county mean. FEMA's separate National Risk Index places the county in the riskiest 8%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Kitsap County is led by Earthquake (about $119.6M Expected Annual Loss, Historical Loss Ratio Very High), while Landslide carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Kitsap County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 229 paid claims, totaling $4.2M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $18.3K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Washington county averages 24.9 federal declaration records, while Kitsap County has 16. The gap is 36% 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 92.3/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $158.3M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Landslide stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 2.8 times per year here.

How often does each hazard strike Kitsap 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 High an average of 2.8 times per year
Earthquake Relatively High roughly once every 30 years
Heat Wave Relatively Moderate 4 modeled event-days per year
Coastal Flooding Relatively Moderate an average of 3.2 times per year
Riverine Flooding Relatively Moderate roughly once every 28 years
Volcanic Activity Very Low roughly once every 1,000 years
Tsunami Relatively Low roughly once every 18 years
Winter Weather Relatively Low an average of 6.3 times per year

What Flood declarations mean here

Flood is the most frequent declaration type on Kitsap County's record, 38% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

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 Kitsap County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. 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

Kitsap County's closest FEMA peer: Washington County, AR

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