The risk behind the insurance bill
FEMA rates Onslow County's overall natural hazard risk Relatively High among US counties. Expected annual losses to buildings, people and agriculture here run about $216 million a year, county-wide, across every building in it, not per household.
One thing to be clear about: the insurance figure above does not know about any of this. It applies your state's average premium rate to the county's median home value, because published premium data does not exist at county level. Two counties in the same state get the same rate here even when FEMA rates one of them Very High and the other Very Low. So in a high-risk county treat the insurance line as a floor, not an estimate, and get a real quote before you budget.
Ratings are FEMA's own, relative to all US counties. A high drought or heat rating also shows up in the climate figures for Onslow County.
