The verdict
Nevada County has a nationally busy FEMA history: 23 declarations, more than 62% of counties in this registry. But the state comparison tempers that reading: the total is 19% below the California county mean. FEMA's separate National Risk Index places the county in the riskiest 10%; that score models loss and vulnerability rather than counting declarations.

Nevada County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Nevada County is led by Riverine Flooding (about $37.4M Expected Annual Loss, Historical Loss Ratio Very High), while Wildfire carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Nevada County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 63 paid claims, totaling $1.1M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $18.2K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
Start with the state benchmark: a California county averages 28.5 federal declaration records, while Nevada County has 23. The gap is 19% 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 89.9/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Moderate (roughly $80.6M in annualized losses). Social vulnerability reads Relatively Moderate and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Wildfire stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 87 years here.

How often does each hazard strike Nevada 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 High | roughly once every 87 years |
| Landslide | Relatively Moderate | an average of 2.3 times per year |
| Earthquake | Relatively Moderate | roughly once every 30 years |
| Riverine Flooding | Relatively Moderate | roughly once every 1 years |
| Avalanche | Relatively High | roughly once every 3 years |
| Lightning | Relatively Moderate | an average of 14 times per year |
| Winter Weather | Relatively Moderate | an average of 28 times per year |
| Volcanic Activity | Very Low | roughly once every 833 years |
| Heat Wave | Relatively Low | 4.3 modeled event-days per year |
| Hail | Relatively Low | roughly once every 6 years |
| Tornado | Very Low | roughly once every 11 years |
| Strong Wind | Very Low | roughly once every 14 years |

What Fire declarations mean here
Fire is the most frequent declaration type on Nevada County's record, 30% 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 Nevada County the two measures on this page point the same way: Wildfire is the county's highest-rated modeled hazard (Relatively High), 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.

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.
