The verdict

Two federal records point in the busier direction for Delaware County. Its 39 FEMA declarations are 59% above the New York county mean and exceed the count for 96% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 17%, based on modeled expected annual loss, social vulnerability, and community resilience.

What does Delaware County's hazard record show?

Reading the federal records together

FEMA's NFIP table contains a substantial paid-claim history for this county: 1,290 claims and $39.6M 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 $30.7K. 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. Delaware County's 39 federal records stand 59% above the New York county mean of 24.5. 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 83.3/100 (Relatively Moderate). Expected Annual Loss is rated Relatively Low (roughly $35.5M in annualized losses). Social vulnerability reads Very High and community resilience Relatively High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Riverine Flooding carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 2.3 times per year here, based on 64 historical events on record.

How often does each hazard strike Delaware 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.

Riverine Flooding Relatively Moderate an average of 2.3 times per year
Landslide Relatively Moderate an average of 2.5 times per year
Hurricane Relatively Low roughly once every 36 years
Winter Weather Relatively Moderate an average of 20 times per year
Cold Wave Relatively Moderate an average of 5 times per year
Avalanche Relatively Low roughly once every 100 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Delaware County's record, 38% 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: Riverine Flooding

Riverine Flooding is the model's measure of a watershed draining more water than its channel can carry. Unlike flash flooding it usually builds over days and is forecast in advance, which makes it the hazard where warning time most reliably converts into reduced harm.

Worth noting for Delaware County: the model and the federal record do NOT point at the same hazard. Riverine Flooding 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.

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