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 city page when you want a recognizable local reference point for comparing nearby ZIPs and counties. Since the percentile is lower than many scored areas, the address-level score is still important for finding property-specific exposure.
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 earthquake layer shown here.
