The verdict

Two federal records point in the busier direction for Ventura County. Its 53 FEMA declarations are 86% above the California county mean and exceed the count for 99% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 1%, based on modeled expected annual loss, social vulnerability, and community resilience.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Ventura County is led by Earthquake (about $391.6M 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 Ventura County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,331 claims and $16.0M 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 $12.0K. 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. Ventura County's 53 federal records stand 86% above the California county mean of 28.5. 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 sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 99.4/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $762.2M in annualized losses). Social vulnerability reads Relatively Low and community resilience Relatively Low, 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 83 years here.

How often does each hazard strike Ventura 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.

Wildfire Relatively High roughly once every 83 years
Earthquake Relatively High roughly once every 13 years
Riverine Flooding Very High an average of 1.9 times per year

What Fire declarations mean here

Fire is the most frequent declaration type on Ventura County's record, 53% 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 Ventura 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.

Data-matched county comparisons

Ventura County's closest FEMA peer: Terrebonne Parish, LA

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

How many flood insurance claims has Ventura County filed?
Ventura County has 1,331 National Flood Insurance Program (NFIP) claims totaling $16.0M in payments, with an average of $12.0K per claim.
Does FEMA's top risk-rated hazard match the highest Expected Annual Loss in Ventura County?
No. In Ventura County, Wildfire has the highest National Risk Index rating (Relatively High), while Earthquake leads Expected Annual Loss at about $391.6M. FEMA's risk score and dollar-loss model use different inputs, so the leaders often differ.
What was the worst year for disasters in Ventura County?
The most active year for disaster declarations in Ventura County was 2020, with 5 declarations. The county has FEMA disaster data spanning 1966 to 2026.
What is the FEMA National Risk Index score for Ventura County?
According to the FEMA National Risk Index, Ventura County, California has an overall risk score of 99.4 out of 100 (Relatively High). On social vulnerability the county rates Relatively Low; on community resilience, Relatively Low. The Expected Annual Loss (EAL) score is Relatively High, representing $762.2M in annualized losses.
Which natural hazard poses the greatest risk to Ventura County?
The top hazard flagged by FEMA's NRI for Ventura County as of the latest release is Wildfire (risk rating: Relatively High). Other significant hazards include Earthquake (Relatively High) and Riverine Flooding (Very High). FEMA's modeled event frequency puts wildfire here at roughly once every 83 years. FEMA derives these ratings from historical event frequency, the assets exposed, and the community's vulnerability profile.
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.
