Flood exposure & the bottom line
Taken together, these indicators place Union County at a high relative risk level, its federal disaster history outpaces most of the country, and it is worth pairing that record with forward-looking hazard maps before making insurance or relocation decisions.

FEMA NRI 8-hazard radar - Union County
How to read this radar
The radar plots Union County's relative exposure to the eight headline natural hazards used by the FEMA National Risk Index. Each axis is the qualitative NRI risk rating (Very Low through Very High) re-expressed on a 0-100 scale so that the polygon shape lets you compare a county against another at a glance. A rounder polygon means broad multi-hazard exposure; a spiky polygon means one or two dominant hazards drive most of the modeled risk.
