Capitol Planning Region, CT: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Capitol Planning Region scores at the 99th percentile for flood hazard, rated "Relatively High" — well above 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 3.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Capitol Planning Region
31.8% of the homes FEMA requires to carry flood insurance in Capitol Planning Region — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 653 policies against 2,055 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.5% of all residential structures in Capitol Planning Region carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
