Flood Zone V is a high-risk coastal flood zone where wave action is part of the concern. In Washington, V zones can matter for properties near the Pacific Coast, Puget Sound, the Strait of Juan de Fuca, and other shoreline areas.
V zones are different from standard river flood zones because the risk can include coastal flooding, wave action, high tides, king tides, storm surge, shoreline erosion, and fast-moving water. Coastal flooding can also be affected by sea level rise, local weather, shoreline shape, and how water moves through bays, inlets, and low-lying coastal areas.
Flood Nerd take: V zones are not just “another flood zone.” They are coastal high-risk zones. If a Washington property is in Zone V or VE, the insurance review needs to be tighter: elevation, foundation, lender requirement, building details, and NFIP vs private options all matter.
