11 FEMA disaster declarations (1965-2020), with a FEMA National Risk Index rating of Relatively High. Most common hazard: Flood.
The verdict
Two federal records point in the busier direction for Denver County. Its 11 FEMA declarations are 8% above the Colorado county mean and exceed the count for 12% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 5%, based on modeled expected annual loss, social vulnerability, and community resilience.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Denver County is led by Riverine Flooding (about $93.6M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Very High). EAL and risk score use different inputs; they need not agree.

The NFIP claims register shows a middle-volume loss record here: 242 paid claims, totaling $719.4K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $3.0K 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. Denver County's 11 federal records stand 8% above the Colorado county mean of 10.2. 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.
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 95.2/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $222.0M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Hail stands out as the sharpest exposure here, rated Very High. FEMA's modeled frequency puts that hazard at an average of 8.3 times per year here, based on 315 historical events on record.

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 | Very High | an average of 8.3 times per year |
| Lightning | Very High | an average of 52 times per year |
| Tornado | Relatively High | roughly once every 6 years |
| Strong Wind | Relatively High | an average of 1.2 times per year |
| Riverine Flooding | Relatively High | roughly once every 1 years |
| Cold Wave | Relatively High | an average of 1.3 times per year |
| Winter Weather | Relatively High | an average of 14 times per year |
| Earthquake | Relatively Moderate | roughly once every 1,490 years |
| Landslide | Relatively Moderate | roughly once every 36 years |
| Volcanic Activity | Very Low | roughly once every 10,000 years |
| Heat Wave | Relatively Low | 1 modeled event-day per year |
| Wildfire | Very Low | roughly once every 1,685 years |
| Drought | Very Low | 21 modeled event-days per year |
| Ice Storm | Very Low | roughly once every 64 years |

Flood is the most frequent declaration type on Denver County's record, 36% 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.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

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 Denver County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Very 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.

Understanding disaster data
Denver County's NFIP claims file (242 claims) and FEMA declaration history measure different federal records - this guide separates them from modeled NRI risk.
Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.
This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.
