The verdict

Benton County has a nationally busy FEMA history: 20 declarations, more than 46% of counties in this registry. But the state comparison tempers that reading: the total is 20% below the Washington county mean. FEMA's separate National Risk Index places the county in the riskiest 13%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Benton County is led by Riverine Flooding (about $40.3M 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 Benton County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 108 paid claims, totaling $1.5M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $13.5K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Washington county averages 24.9 federal declaration records, while Benton County has 20. The gap is 20% 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 87.1/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $69.8M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively Moderate, both critical modifiers of realized harm here. 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 92 years here.

How often does each hazard strike Benton 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.

Wildfire Relatively Moderate roughly once every 92 years
Heat Wave Relatively Moderate 7.9 modeled event-days per year
Earthquake Relatively Moderate roughly once every 174 years
Winter Weather Relatively High an average of 7.9 times per year
Riverine Flooding Relatively Moderate roughly once every 3 years
Ice Storm Relatively High roughly once every 4 years
Cold Wave Relatively Moderate roughly once every 2 years
Volcanic Activity Very Low roughly once every 76 years

What Flood declarations mean here

Flood is the most frequent declaration type on Benton County's record, 45% 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 Benton 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

Benton County's closest FEMA peer: Stafford County, VA

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