How much flood risk does Greater Bridgeport Planning Region actually carry?
Greater Bridgeport Planning Region lands at the 94.8th percentile of FEMA's National Risk Index for flooding, "Very High" territory — among the highest flood hazard in the country — with the hazard split between inland river flooding (about 3.5 times a year) and coastal storm surge (about 6.2 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.
