The verdict
Two federal records point in the busier direction for Plaquemines Parish. Its 45 FEMA declarations are 9% above the Louisiana county mean and exceed the count for 98% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 27%, based on modeled expected annual loss, social vulnerability, and community resilience.

What does Plaquemines Parish's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 6,086 claims and $381.7M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $62.7K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
The declaration register points in the busier direction. Plaquemines Parish's 45 federal records stand 9% above the Louisiana county mean of 41.4. 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.
FEMA National Risk Index
This county carries a high composite score on FEMA's National Risk Index, 72.9/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $28.1M in annualized losses), and a Relatively Moderate social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Hurricane stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 4 years here, based on 134 historical events on record.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 45 entries for Plaquemines Parish, including 26 Major Disaster records, 9% above the Louisiana county mean. Across the 61-year span, that works out to 0.7 declarations a year. Hurricane leads the file with 32 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Plaquemines 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.

|---|---|---|
| Hurricane | Relatively High | roughly once every 4 years |
| Coastal Flooding | Relatively High | an average of 4 times per year |
| Drought | Relatively Moderate | 28 modeled event-days per year |
| Heat Wave | Relatively Low | 11 modeled event-days per year |
| Lightning | Relatively Low | an average of 81 times per year |
| Cold Wave | Relatively Low | roughly once every 2 years |
| Tornado | Relatively Low | roughly once every 1 years |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on Plaquemines Parish's federal record, 71% 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 Plaquemines Parish the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Relatively High), 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.
