How is the $95,000 exposure calculated?
The exposure estimate is based on industry-standard cost models: NFIP average flood insurance claims, USGS earthquake damage probability models, CAL FIRE wildfire rebuilding cost data, and historical disaster costs from OpenFEMA. It represents the estimated financial impact of the identified risks based on what these events actually cost homeowners. Individual properties will vary based on exact location, construction, elevation, and proximity to specific hazards.
