The verdict

Union County has a nationally busy FEMA history: 16 declarations, more than 27% of counties in this registry. But the state comparison tempers that reading: the total is 8% below the Georgia county mean. FEMA's separate National Risk Index places the county in the riskiest 48%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Union County is led by Riverine Flooding (about $5.8M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Union 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 $672.4K. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $11.4K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Georgia county averages 17.4 federal declaration records, while Union County has 16. The gap is 8% 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, 52.5/100, rated Relatively Low. Its Expected Annual Loss rating is Very Low (roughly $11.6M in annualized losses), and a Very High social-vulnerability profile combined with Relatively Low community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 1.1 times per year here.

How often does each hazard strike Union 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
Landslide Relatively Moderate an average of 1.1 times per year
Cold Wave Relatively Moderate an average of 2.4 times per year
Wildfire Relatively Low roughly once every 455 years
Lightning Relatively Moderate an average of 61 times per year
Earthquake Relatively Low roughly once every 317 years
Tornado Relatively Low roughly once every 6 years
Ice Storm Relatively Moderate an average of 1.2 times per year
Riverine Flooding Relatively Low roughly once every 2 years
Hurricane Very Low roughly once every 49 years
Drought Relatively Low 36 modeled event-days per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Union County's federal record, 38% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Union County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Hurricane. 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.

Data-matched county comparisons

Union County's closest FEMA peer: Apache County, AZ

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Union County. Record similarity, not a safety rating.

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.
