The verdict

Clark 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 32% 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 Clark County is led by Riverine Flooding (about $68.3M Expected Annual Loss, Historical Loss Ratio Relatively High), while Earthquake carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Clark County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 162 paid claims, totaling $2.3M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $14.4K 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 Clark County has 17. The gap is 32% 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 92.2/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $157.5M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Earthquake carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 46 years here.

How often does each hazard strike Clark 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.

Earthquake Relatively Moderate roughly once every 46 years
Cold Wave Relatively High roughly once every 4 years
Heat Wave Relatively Moderate 7 modeled event-days per year
Riverine Flooding Relatively Moderate roughly once every 3 years
Ice Storm Relatively High an average of 1.9 times per year
Volcanic Activity Relatively Low roughly once every 81 years
Strong Wind Relatively Moderate roughly once every 22 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Clark County's record, 35% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.

These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.

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: Earthquake

Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.

Worth noting for Clark County: the model and the federal record do NOT point at the same hazard. Earthquake carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. 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

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

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