How Poquoson city floods

Coastal flooding dominates the flood history of Poquoson city, accounting for the majority of recorded events over the last 30 years alongside flash floods and tropical storms. Prolonged northeast winds driven by coastal lows and high pressure systems frequently push water from the Chesapeake Bay and surrounding rivers onto land, causing minor to major tidal flooding. For example, a coastal low and high pressure system produced widespread moderate to major coastal flooding on October 12, 2025. Similarly, Tropical Storm Ophelia brought strong winds and moderate to major tidal flooding on September 23, 2023, while another low pressure surge caused moderate coastal flooding on November 15, 2024.

National Flood Insurance Program claims data shows impacts across multiple zones, with the vast majority concentrated in Zone A at 4,135 claims with an average payout of $16,956 and an average recorded water depth of 8 inches. Zone V recorded 64 claims with an average payout of $19,854 and an average water depth of 7 inches, while Zone X recorded 55 claims with an average payout of $19,680 and an average water depth of 9 inches. Zone X shaded recorded 12 claims with an average payout of $5,793 and an average water depth of 14 inches, and unknown zones recorded 23 claims with an average payout of $6,906 and an average water depth of 2 inches. Property owners in Zone A and coastal zones should pay the most attention to flood risk given the high volume of historical claims.

Where the flood claims came from

From the storm reports

Coastal Flood · Oct 12, 2025. A coastal low formed off of the Southeast coast on October 11 and slowly tracked north into October 13 before moving offshore. Meanwhile, a strong 1035mb area of high pressure lingered over the Gulf of Saint Lawrence. This resulted in a prolonged period of strong northeast to north winds across the Chesapeake Bay and coastal waters, which allowed for widespread moderate to major coastal flooding across eastern Vir…

Coastal Flood · Sep 20, 2024. The combination of strong high pressure over eastern Canada and weak low pressure off the southern New England coast, resulted in prolonged northeast, east and southeast winds which caused minor to moderate (tidal) coastal flooding across portions of the York River.

Coastal Flood · Nov 15, 2024. An area of low pressure moved across the Outer Banks and out to sea on the night of November 14 into November 15. Winds became northeast ahead of the low and northwest behind the low as it moved offshore on November 15. The result was a surge of water from the Chesapeake Bay with moderate coastal flooding reported across several areas.

Coastal Flood · Sep 23, 2023. Tropical Storm Ophelia tracked northward across east central North Carolina and up through central Virginia from early Saturday morning, September 23rd into early Sunday morning, September 24th. The combination of high pressure to the north and the storm resulted in very strong northeast, east and then southeast winds which caused moderate to major (tidal) coastal flooding across portions of the York River.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Poquoson city

If a building in Poquoson city is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
