About this state

FEMA disaster context for Utah

Utah has 240 county-level FEMA disaster declarations spread across 29 counties. The most common declaration type is flood. Across all counties, FEMA datasets track $545.5M in combined public and individual assistance obligations.

The counties with the heaviest disaster history are Washington County (14 declarations), Salt Lake County (12), and Utah County (12). Each county page breaks down the timeline, hazard mix, spending categories, and flood insurance signals for that specific area.

Declaration counts reflect how often FEMA formally declared a disaster or emergency affecting a county — not the total number of natural events. A single hurricane can generate declarations across dozens of counties and multiple states. The county pages linked above show the per-county detail behind these state-level totals.
