How Washington County floods

Washington County experiences flood risks dominated by tropical storms and hurricanes, which account for the majority of severe weather events over the last 30 years alongside flash floods, standard floods, and storm surges. Recent historic impacts include Hurricane Dorian in September 2019 and Tropical Storm Isaias in August 2020, both bringing significant tropical weather to the region. Tropical Storm Ian followed in September 2022, producing elevated water levels, heavy rainfall of 3 to 6 inches, tropical storm-force winds, and a tornado.

NFIP claims data demonstrates that flood risks extend across multiple zones, with the highest concentration occurring in Zone A, which recorded 126 claims with an average water depth of 3 inches and an average payout of $17,757. Properties located outside of primary high-risk areas also experience significant impacts; Zone X recorded 24 claims with an average water depth of 2 inches and an average payout of $38,597, while Shaded Zone X recorded 4 claims with an average water depth of 2 inches and an average payout of $64,474. Unshaded Zone X recorded 3 claims with an average water depth of 1 inch and an average payout of $7,312. Homeowners, real estate agents, and journalists should pay close attention to properties across all mapped zones, as moderate- and low-risk areas frequently sustain substantial financial losses during major tropical events.

Where the flood claims came from

5% of Washington County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 3 inches.

From the storm reports

Tropical Storm · Sep 30, 2022. Ian initially made landfall on the west coast of Florida as a major category 4 hurricane, and then crossed into the Atlantic and moved northward, making a second landfall on the South Carolina coast near Georgetown as a category 1 hurricane. For Eastern NC, tropical storm force winds, elevated water levels, heavy rainfall of 3 to 6 inches, and a tornado were associated with Ian. Strong high pressure over New Engla…

Tropical Storm · Aug 4, 2020. Hurricane Isaias originated from a vigorous tropical wave off the coast of Africa that was first identified by the National Hurricane Center on July 23, 2020. The tropical wave gradually became more organized, and became Tropical Storm Isaias on July 30. Isaias marked the earliest ninth named storm on record, surpassing 2005's Hurricane Irene by eight days. Isaias strengthened into a Category 1 hurricane the next…

Tropical Storm · Sep 6, 2019. Hurricane Dorian was the fourth named storm, second hurricane, and first major hurricane of the 2019 Atlantic hurricane season. Dorian formed on August 24, 2019 from a tropical wave in the Central Atlantic and gradually strengthened as it moved toward the Lesser Antilles, becoming a hurricane on August 28. Rapid intensification occurred, and on August 31, Dorian became a Category 4 hurricane. On September 1, Doria…

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Washington County

If a building in Washington County 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.
