The verdict
Sherburne County has a nationally busy FEMA history: 10 declarations, more than 10% of counties in this registry. But the state comparison tempers that reading: the total is 44% below the Minnesota county mean. FEMA's separate National Risk Index places the county in the riskiest 46%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Sherburne County is led by Riverine Flooding (about $17.0M Expected Annual Loss, Historical Loss Ratio Relatively High), 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 Sherburne County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 59 paid claims, totaling $478.3K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $8.1K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a Minnesota county averages 17.7 federal declaration records, while Sherburne County has 10. The gap is 44% 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 carries a high composite score on FEMA's National Risk Index, 53.6/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $30.8M in annualized losses), and a Very Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. 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 4 times per year here, based on 153 historical events on record.
Declaration frequency
Nationally, Sherburne County's 10 FEMA records form a high-volume history; within Minnesota, however, the count is 44% below the county mean. 7 entries carry the Major Disaster classification. The largest incident group is Flood, appearing 4 times. The full 55-year record averages 0.2 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Sherburne 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 4 times per year |
| Hail | Relatively Moderate | an average of 6.1 times per year |
| Wildfire | Relatively Low | roughly once every 871 years |
| Tornado | Relatively Moderate | roughly once every 4 years |
| Riverine Flooding | Relatively Low | roughly once every 5 years |
| Drought | Relatively Low | 9.1 modeled event-days per year |
| Lightning | Relatively Moderate | an average of 34 times per year |
| Heat Wave | Relatively Low | 3.4 modeled event-days per year |
| Cold Wave | Relatively Low | an average of 11 times per year |
| Winter Weather | Relatively Low | an average of 17 times per year |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 15 years |
| Earthquake | Very Low | roughly once every 4,566 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Sherburne County's record, 40% 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 Sherburne 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.
