Columbus County, NC: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Columbus County scores at the 64.6th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.1 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
32.6% of the homes FEMA requires to carry flood insurance in Columbus County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 232 policies against 711 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 2.2% of all residential structures in Columbus County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
