Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Muscatine County is led by Riverine Flooding (about $10.1M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Muscatine County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 355 paid claims, totaling $5.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $15.9K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Muscatine County's 21 federal records stand 9% above the Iowa county mean of 19.3. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

This county carries a high composite score on FEMA's National Risk Index, 57.8/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $20.3M in annualized losses), and a Relatively Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 4.3 times per year here, based on 164 historical events on record.

How often does each hazard strike Muscatine 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
Hail Relatively Moderate an average of 4.3 times per year
Strong Wind Relatively High an average of 6.4 times per year
Drought Relatively Moderate 9.7 modeled event-days per year
Heat Wave Relatively Low 7.3 modeled event-days per year
Ice Storm Relatively Moderate roughly once every 2 years
Lightning Relatively Moderate an average of 45 times per year
Landslide Relatively Low roughly once every 11 years
Winter Weather Relatively Moderate an average of 15 times per year
Riverine Flooding Relatively Low an average of 2.5 times per year

What Flood declarations mean here

Flood is the most frequent declaration type on Muscatine County's record, 48% 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: Hail

Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.

Worth noting for Muscatine County: the model and the federal record do NOT point at the same hazard. Hail 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

Muscatine County's closest FEMA peer: Butte County, SD

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