The verdict

Union Parish has a nationally busy FEMA history: 36 declarations, more than 94% of counties in this registry. But the state comparison tempers that reading: the total is 13% below the Louisiana county mean. FEMA's separate National Risk Index places the county in the riskiest 50%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Union Parish is led by Riverine Flooding (about $5.6M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Ice Storm carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Union Parish's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 379 paid claims, totaling $9.0M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $23.8K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Louisiana county averages 41.4 federal declaration records, while Union Parish has 36. The gap is 13% 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

FEMA's data shows an elevated National Risk Index composite of 49.7/100 for this county (Relatively Low rating). Expected Annual Loss comes in at Very Low (roughly $10.6M in annualized losses). Social vulnerability (Very High) and community resilience (Relatively Low) both factor into how that raw exposure plays out on the ground. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 1.3 times per year here, based on 87 historical events on record.

Declaration frequency

Nationally, Union Parish's 36 FEMA records form a high-volume history; within Louisiana, however, the count is 13% below the county mean. 21 entries carry the Major Disaster classification. The largest incident group is Hurricane, appearing 17 times. The full 49-year record averages 0.7 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Union Parish?

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.

Ice Storm Relatively High an average of 1.3 times per year
Strong Wind Relatively High an average of 3.8 times per year
Heat Wave Relatively Low 21 modeled event-days per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Union Parish's federal record, 47% 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: Ice Storm

Ice storms load power lines and tree limbs with accumulating freezing rain until they fail. The characteristic cost is infrastructure and multi-day power loss across a wide area rather than structural damage to buildings, which is why their consequences often outlast the weather that caused them.

Worth noting for Union Parish: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Relatively High), 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.

Union Parish's closest FEMA peer: Orange County, NY

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Union Parish. 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.

Data Sources & Methodology

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.

What this means for Union Parish

Against a Louisiana county mean of 41 declarations, Union Parish, LA records 36, or 13% fewer. PlainHazard classifies that historical total as high activity.

  • Major Disaster is the largest group (21 of 36) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Louisiana overview
  • Nationally the county exceeds 94% of recorded county totals, but its own Louisiana benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
