Financial Risk Inventory
Recommended investments to protect your property value and reduce insurance liability based on your local risk profile.
Heat Wave Mitigation
Ensure attic insulation is R-49+ and consider a dual-fuel backup generator for AC.

Cold Wave Mitigation
General property maintenance and insurance review recommended.

Sources and Methodology
Spatial Aggregation
Our "Atlas" risk scores are derived using a population-weighted spatial join. Because US Zip Codes and Census Tracts do not share perfectly aligned boundaries, a simple geographic average would be misleading. We utilize US Census Block Group population statistics to identify where residents actually live within a Zip Code. We then intersect these points with FEMA National Risk Index (NRI) hazard data to calculate a weighted exposure score.
Financial Projections (EAL)
Expected Annual Loss (EAL) estimates the average economic impact of natural hazards in dollars per year. This calculation incorporates three components: Exposure (the value of structures and agriculture), Annualized Frequency (historical probability), and Historic Loss Ratio (vulnerability of the area).
