How to read the location signal
This page uses the representative local model area around the county or parish centroid for Oglala Lakota County, South Dakota. That local model area is roughly 5 square kilometers, so the score is a practical place-level signal for browsing and comparison. The building-level view comes from entering a street address.
The confidence value is unavailable or very limited in this snapshot, so the page should be treated as a starting point.

Why building details matter
A street-address score can account for the unique characteristics of a specific building, including age, construction type, roof shape and condition, occupancy, elevation, defensible space, drainage, terrain, and nearby exposure. Those details can change resilience or susceptibility around the same location-level score.
Use this county page as the broadest browse layer before drilling into city and ZIP pages. Since the percentile is elevated, it is worth comparing nearby pages before relying on the area score alone.
Use the PerilScore app to enter a street address and see the full property-specific score.
The local score is the starting point
A specific building can perform differently from the surrounding area. The PerilScore street-address check adds building age, construction type, roof details, occupancy, elevation, defensible space, drainage, terrain, and nearby exposure to the hail layer shown here.
