Columbia City anchors Rainier Valley, the corridor running south from the Central District toward Renton along the Rainier Avenue spine. The Rainier Valley is one of the most ethnically diverse ZIP codes in the United States, home to communities from East Africa, Southeast Asia, Latin America, and the Pacific Islands, as well as long-established Black and Filipino communities. Columbia City, platted in 1890, became a National Historic District in 1980 thanks to its intact Craftsman and Victorian commercial buildings; it has been revitalized in recent decades as a restaurant and arts destination without losing its neighborhood character.
The Link Light Rail, extended to Columbia City in 2009, connected this southern corridor to downtown and the airport for the first time, beginning a shift in development pressure that is still reshaping the neighborhood. Mount Rainier, the 14,411-foot stratovolcano that dominates the southeastern horizon, gives the valley its name and its most dramatic landmark. On clear days the mountain is overwhelming: an ice-covered mass that seems too large to be real, floating above the horizon, reminding everyone in the city that they live inside a geologically active landscape that operates on a timescale dwarfing any human ambition.
