Scores are 0–100 percentiles relative to all US counties — higher means more exposed, not that a disaster is likely this year. Event counts: NOAA Storm Events 2016–2026; earthquake counts from USGS ComCat (M3.0+, 1996–2026). See the methodology page for details.

Community vulnerability

Norfolk ranks in the 86th percentile (High) for community vulnerability — a measure of how hard disaster impacts tend to hit residents. Higher vulnerability means more displacement, worse health outcomes, and slower recovery after a disaster.

Minor flood days/yr, 1928–2026

Projected days per year of high-tide flooding, by NOAA's severity tiers based on how far water rises above the normal high tide: minor (road closures, stormwater backup — disruptive, not damaging), moderate (can damage homes and businesses), and major (threat to life and property, often requires evacuation).
