The verdict

LaSalle Parish has a nationally busy FEMA history: 38 declarations, more than 95% of counties in this registry. But the state comparison tempers that reading: the total is 8% below the Louisiana county mean. FEMA's separate National Risk Index places the county safer than 12%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

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

What does LaSalle Parish's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 271 paid claims, totaling $3.4M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $12.6K 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 LaSalle Parish has 38. 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.

Declaration frequency

Nationally, LaSalle Parish's 38 FEMA records form a high-volume history; within Louisiana, however, the count is 8% below the county mean. 21 entries carry the Major Disaster classification. The largest incident group is Hurricane, appearing 17 times. The full 53-year record averages 0.7 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

FEMA National Risk Index

FEMA's National Risk Index places this county in the low end of the national distribution, composite score 12.2/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $5.0M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Relatively Moderate) and community resilience (Relatively High). Even the county's top-rated hazard, Hurricane, 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 15 years here, based on 22 historical events on record.

How often does each hazard strike LaSalle 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.

Heat Wave Relatively Low 22 modeled event-days per year
Ice Storm Relatively Low roughly once every 1 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on LaSalle Parish's federal record, 45% 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: Hurricane

Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.

For LaSalle Parish the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Relatively Low), and Hurricane 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.

Data-matched county comparisons

LaSalle Parish's closest FEMA peer: Suffolk County, MA

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

Against a Louisiana county mean of 41 declarations, LaSalle Parish, LA records 38, or 8% fewer. PlainHazard classifies that historical total as high activity.

  • Major Disaster is the largest group (21 of 38) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Louisiana overview
  • Nationally the county exceeds 95% of recorded county totals, but its own Louisiana benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
