Vanport: The City That Disappeared in an Afternoon

The notice went up on May twenty-seventh, nineteen forty-eight. It was a single sheet of paper posted at the doors of the housing project offices. "Remember," it read, "the dike is safe at present. You will be warned if necessary. You will have time to leave."

Three days later, at four seventeen in the afternoon, the railroad dike on the west side failed.

Vanport was the second-largest city in Oregon. It had been built in one hundred ten days in nineteen forty-two on Columbia River floodplain, a wartime emergency housing project for Kaiser Shipyard workers. At its peak it held forty-two thousand people. By the spring of nineteen forty-eight it held roughly eighteen thousand five hundred, including approximately six thousand three hundred Black residents who lived there not by preference but because restrictive racial covenants made it impossible for them to rent or buy in most Portland neighborhoods. The Housing Authority of Portland had already used those covenants, quietly, to concentrate its Black tenants in Vanport rather than scatter them across the city.

When the dike failed, the water moved fast. Within minutes it was chest-high in the lower blocks. People grabbed children and ran. The entire city was under water within a single hour.

The official death toll from the flood stood at approximately fifteen. Some accounts, accounting for residents who died of illness and exposure in the weeks that followed, place the figure as high as twenty-six. What is established is that virtually every one of the eighteen thousand five hundred residents lost everything they owned.

The aftermath was its own catastrophe. Black Vanport residents had almost nowhere to go. Racial covenants still covered most of Portland. Several families made their way to the Albina neighborhood in Northeast Portland, already the city's most concentrated Black district. They crowded into housing that was not built for the numbers now arriving. Landlords in Albina knew it.

The Housing Authority issued no formal apology. Several lawsuits were filed. None resulted in compensation. The "dike is safe" notice, published just hours before the failure, would become one of the most quoted documents in Oregon civil-rights history.

The site is now Delta Park and the Columbia Slough wetlands. There is no formal landmark. Most of what Vanport was has been reclaimed by the river that erased it.
