Clackamas County's FEMA Risk Index score
What does Clackamas County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 816 claims and $24.3M 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 $29.8K. 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. Clackamas County's 23 federal records stand 38% above the Oregon county mean of 16.6. 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 94.9/100 (Relatively High). Expected Annual Loss is rated Relatively High (roughly $219.1M in annualized losses). Social vulnerability reads Very Low and community resilience Relatively High, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Earthquake stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 66 years here.

How often does each hazard strike Clackamas 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 |
|---|---|---|
| Earthquake | Relatively High | roughly once every 66 years |
| Landslide | Relatively Moderate | an average of 1.9 times per year |
| Volcanic Activity | Relatively Moderate | roughly once every 81 years |
| Heat Wave | Relatively Moderate | 4.9 modeled event-days per year |
| Cold Wave | Relatively High | roughly once every 3 years |
| Riverine Flooding | Relatively High | roughly once every 1 years |
| Strong Wind | Relatively High | roughly once every 13 years |
| Ice Storm | Relatively High | an average of 1.1 times per year |
| Wildfire | Relatively Low | roughly once every 1,542 years |
| Avalanche | Relatively High | roughly once every 8 years |
| Winter Weather | Relatively High | an average of 26 times per year |
| Lightning | Relatively High | an average of 8.4 times per year |
| Tornado | Relatively Low | roughly once every 7 years |
| Hail | Very Low | roughly once every 8 years |
| Coastal Flooding | Very Low | roughly once every 3 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Clackamas County's record, 35% 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: Earthquake
Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.
Worth noting for Clackamas County: the model and the federal record do NOT point at the same hazard. Earthquake carries the highest modeled rating (Relatively High), 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.
