Chittenden County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Chittenden County is led by Riverine Flooding (about $28.8M Expected Annual Loss, Historical Loss Ratio Relatively High), while Winter Weather carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Chittenden County's hazard record show?
Reading the federal records together
The NFIP claims register shows a middle-volume loss record here: 256 paid claims, totaling $4.0M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $15.7K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.
The declaration register points in the busier direction. Chittenden County's 32 federal records stand 11% above the Vermont county mean of 28.8. 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, 63.9/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $40.1M in annualized losses), and a Very Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Winter Weather carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 17 times per year here, based on 317 historical events on record.

How often does each hazard strike Chittenden 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 |
|---|---|---|
| Winter Weather | Relatively Moderate | an average of 17 times per year |
| Lightning | Relatively High | an average of 23 times per year |
| Avalanche | Relatively Moderate | roughly once every 30 years |
| Ice Storm | Relatively Moderate | roughly once every 3 years |
| Earthquake | Relatively Low | roughly once every 360 years |
| Landslide | Relatively Low | roughly once every 1 years |
| Riverine Flooding | Relatively Moderate | an average of 2.1 times per year |
| Heat Wave | Relatively Low | 2.1 modeled event-days per year |
| Hurricane | Relatively Low | roughly once every 38 years |
| Strong Wind | Relatively Moderate | roughly once every 1 years |
| Cold Wave | Relatively Low | an average of 3.5 times per year |
| Tornado | Relatively Low | roughly once every 35 years |
| Wildfire | Very Low | roughly once every 13,789 years |
| Hail | Very Low | an average of 1.1 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Chittenden County's record, 44% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.
These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.
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: Winter Weather
Winter Weather in the model means the accumulation of snow and cold that disrupts rather than destroys: road closures, roof loads, burst pipes and lost heating. Its costs land heavily on transport and on households least able to absorb an interruption.
Worth noting for Chittenden County: the model and the federal record do NOT point at the same hazard. Winter Weather carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. 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 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.
