Climate-Adjusted Hazard Data · Model Version 1.0
Washington experiences riverine flooding from atmospheric river events and snowmelt, particularly in the Skagit, Nooksack, and Chehalis river valleys. Urban flooding affects the Puget Sound metro area. Lahar hazard from Mount Rainier represents a unique volcanic-flood compound risk for the Puyallup and Nisqually valleys.
CivilSense computes a Climate-Adjusted Hazard Score (0–10) for flood hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and peer-reviewed research. All score components are transparent and returned in API responses.
These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
