Norfolk city, VA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Norfolk city scores at the 82.4th percentile for flood hazard, rated "Relatively High" — well above the national norm for flood hazard. The hazard here is split between inland river flooding (about 1.8 times a year) and coastal storm surge (about 3.6 times a year). This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Norfolk city's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Norfolk city's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 14.1% of all residential structures in Norfolk city carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Norfolk city compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Norfolk city ranks 576 — 1 being the highest hazard nationally — and 313 by population among all 3144 counties covered here, where 1 is the largest. Norfolk city, Virginia is home to about 231,105 people across 53.275 square miles of land.
