Scott County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Scott County is led by Riverine Flooding (about $39.9M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Strong Wind carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Scott County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 2,265 claims and $34.9M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $15.4K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
The declaration register points in the busier direction. Scott County's 20 federal records stand 4% 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 84.9/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $66.5M in annualized losses). Social vulnerability reads Very Low and community resilience Very High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Strong Wind stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 6.3 times per year here, based on 238 historical events on record.

How often does each hazard strike Scott 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 |
|---|---|---|
| Strong Wind | Relatively High | an average of 6.3 times per year |
| Hail | Relatively High | an average of 4 times per year |
| Riverine Flooding | Relatively Moderate | an average of 3.5 times per year |
| Winter Weather | Relatively High | an average of 16 times per year |
| Heat Wave | Relatively Moderate | 7.2 modeled event-days per year |
| Ice Storm | Relatively High | roughly once every 2 years |
| Lightning | Relatively High | an average of 43 times per year |
| Drought | Relatively Moderate | 9.3 modeled event-days per year |
| Tornado | Relatively Moderate | roughly once every 2 years |
| Cold Wave | Relatively Moderate | an average of 6.5 times per year |
| Earthquake | Relatively Low | roughly once every 970 years |
| Landslide | Relatively Low | roughly once every 8 years |
| Wildfire | Very Low | roughly once every 1,689 years |
| Hurricane | Very Low | roughly once every 174 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Scott County's record, 55% 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: Strong Wind
Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.
Worth noting for Scott County: the model and the federal record do NOT point at the same hazard. Strong Wind 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.
