The verdict

Asotin County has a nationally busy FEMA history: 13 declarations, more than 17% of counties in this registry. But the state comparison tempers that reading: the total is 48% below the Washington county mean. FEMA's separate National Risk Index places the county safer than 18%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Asotin County is led by Riverine Flooding (about $3.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Wildfire carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Asotin County's hazard record show?

FEMA National Risk Index

This county's FEMA National Risk Index composite lands at 17.9/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $5.4M in annualized losses), tempered or compounded by a Relatively High social-vulnerability score and Relatively Low community-resilience score. Among the 18 modeled hazards, Wildfire carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 132 years here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 4 claims and $54.5K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

Start with the state benchmark: a Washington county averages 24.9 federal declaration records, while Asotin County has 13. The gap is 48% 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.

How often does each hazard strike Asotin 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
Wildfire Relatively Moderate roughly once every 132 years
Landslide Relatively Low roughly once every 2 years
Avalanche Relatively Low roughly once every 100 years
Heat Wave Relatively Low 3.8 modeled event-days per year
Riverine Flooding Relatively Low roughly once every 3 years
Earthquake Very Low roughly once every 848 years
Winter Weather Very Low an average of 13 times per year
Cold Wave Very Low roughly once every 11 years
Drought Very Low 29 modeled event-days per year

What Flood declarations mean here

Flood is the most frequent declaration type on Asotin 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: Wildfire

Wildfire risk in the model reflects fuel, terrain, weather and how much development sits in the wildland-urban interface. It is one of the few hazards where the exposure is materially changed by land management and building choices, not only by where the county happens to be.

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

Asotin County's closest FEMA peer: Haskell County, KS

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