What a report contains

The USPR Score ranks a ZIP area's modelled natural-hazard losses against every US ZIP area, from 0 to 100. It is built on FEMA's National Risk Index, which estimates expected yearly building losses from 17 hazards including flooding, hurricanes, tornadoes, earthquakes and wildfire. The national median is about $132 a year per $100,000 of building value. How the score is calculated

The flood map section counts buildings in each FEMA flood zone, so you can see how much of the area sits in the Special Flood Hazard Area where flood insurance can be mandatory.

Flood insurance figures are real policies, not models: the number of National Flood Insurance Program policies in force, their median annual cost and the area's claims history back to 1978.

Environmental sites are named, with their distance and EPA status: Superfund National Priorities List sites, Toxics Release Inventory reporters and brownfields.

A due diligence checklist lists the steps the data points to, such as an Elevation Certificate, a Phase I environmental site assessment or the 2027 flood map change.
