Platte County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Platte County is led by Riverine Flooding (about $2.6M Expected Annual Loss, Historical Loss Ratio Relatively High), while Wildfire carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Platte County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 25.7/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $5.9M in annualized losses), tempered or compounded by a Very High social-vulnerability score and Very Low community-resilience score. Even the county's top-rated hazard, Wildfire, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 329 years here.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 1 claim and $0 paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.
The declaration register points in the busier direction. Platte County's 8 federal records stand 40% above the Wyoming county mean of 5.7. 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.

How often does each hazard strike Platte 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 |
|---|---|---|
| Wildfire | Relatively Low | roughly once every 329 years |
| Winter Weather | Relatively Moderate | an average of 18 times per year |
| Cold Wave | Relatively Moderate | an average of 3.6 times per year |
| Hail | Relatively Low | an average of 3 times per year |
| Ice Storm | Relatively Low | roughly once every 35 years |
| Lightning | Relatively Low | an average of 47 times per year |
| Landslide | Very Low | an average of 1.3 times per year |
| Earthquake | Very Low | roughly once every 1,134 years |
| Drought | Relatively Low | 77 modeled event-days per year |
| Tornado | Relatively Low | roughly once every 2 years |
| Riverine Flooding | Very Low | roughly once every 1 years |
| Strong Wind | Relatively Low | roughly once every 2 years |
| Heat Wave | Very Low | 0.3 modeled event-days per year |
| Avalanche | Very Low | roughly once every 100 years |

What Fire declarations mean here
Fire is the most frequent declaration type on Platte County's record, 25% of its declarations. Wildfire is the one hazard here with its own dedicated federal instrument: the Fire Management Assistance Grant, which appears in this data as an FM record. An FMAG can be authorised while a fire is still burning, on a timescale of hours, because its purpose is to reimburse the cost of fighting a fire that threatens to become a major disaster.
That distinction matters when comparing counties. An FM declaration is not a presidential major disaster declaration and does not carry the same assistance programmes, so a fire-heavy county's total is not directly comparable with a hurricane-heavy county's total unless the declaration types are separated, which is why they are listed separately on this page.
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.
For Platte County the two measures on this page point the same way: Wildfire is the county's highest-rated modeled hazard (Relatively Low), and Fire declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.
National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.
