Climate Risk for Zip Code 52338
Financial Exposure & Physical Hazard Analysis
Risk Summary
The primary drivers of climate-related financial risk in zip code 52338 are Tornado, Inland Flooding, and Strong Wind. This area also faces an unusually high intensity for Cold Wave, Hail, Drought, Wildfire, and Landslide compared to national averages.
Understanding the Dollars
Expected Annual Loss (EAL) is a statistical average of property damage for this entire zip code over a standard year across all properties.
- / It represents the "average cost" rather than a guaranteed yearly bill.
- / It can be used to compare the relative risk from different hazards and across different neighborhoods.

Financial Risk Inventory
Recommended Mitigation Strategies
Recommended investments to protect your property value and reduce insurance liability based on your local risk profile.
Tornado Mitigation
Reinforce garage doors and consider a FEMA-approved safe room or storm cellar.
Inland Flooding Mitigation
Install a smart sump pump with battery backup and extend downspouts 10ft from foundation.
Strong Wind Mitigation
Trim large trees back from the roofline and reinforce roof-to-wall connectors (hurricane straps).
Cold Wave Mitigation
General property maintenance and insurance review recommended.
Hail Mitigation
Replace roof with Class 4 impact-resistant shingles to significantly lower insurance premiums.
Drought Mitigation
General property maintenance and insurance review recommended.
Wildfire Mitigation
Create a 5ft 'non-combustible' zone around your home using gravel or pavers instead of mulch.
Landslide Mitigation
Professional slope stabilization and foundation drainage inspection is highly recommended.
Methodology and Sources
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).
