The verdict

Doña Ana County has a nationally busy FEMA history: 10 declarations, more than 10% of counties in this registry. But the state comparison tempers that reading: the total is 20% below the New Mexico county mean. FEMA's separate National Risk Index places the county in the riskiest 4%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Doña Ana County is led by Riverine Flooding (about $133.2M Expected Annual Loss, Historical Loss Ratio Relatively High), while Drought carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Doña Ana County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 208 paid claims, totaling $4.9M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $23.5K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a New Mexico county averages 12.5 federal declaration records, while Doña Ana County has 10. The gap is 20% 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 96.1/100 (Relatively High). Expected Annual Loss is rated Relatively Moderate (roughly $163.6M in annualized losses). Social vulnerability reads Relatively High and community resilience Very Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Drought stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at 74 modeled event-days per year here, based on 2,772 historical events on record.

How often does each hazard strike Doña Ana 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
Drought Relatively High 74 modeled event-days per year
Riverine Flooding Relatively High an average of 2.5 times per year
Winter Weather Very High an average of 2.4 times per year
Lightning Very High an average of 52 times per year
Hail Relatively High roughly once every 2 years
Heat Wave Relatively Moderate 4.4 modeled event-days per year
Earthquake Relatively Moderate roughly once every 661 years
Wildfire Relatively Low roughly once every 3,254 years
Cold Wave Relatively Moderate roughly once every 9 years
Ice Storm Relatively Moderate roughly once every 24 years
Strong Wind Relatively Moderate roughly once every 3 years
Landslide Very Low roughly once every 2 years

What Flood declarations mean here

Flood is the most frequent declaration type on Doña Ana County's record, 30% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.

Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.

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: Drought

Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.

Worth noting for Doña Ana County: the model and the federal record do NOT point at the same hazard. Drought carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. 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-matched county comparisons

Doña Ana County's closest FEMA peer: New Hanover County, NC

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