The largely Italian-American First Ward was one of the hardest hit by urban renewal. A 46-acre (19 hectare) housing tract, labeled a slum because it had dense older housing, was torn down for multi-story, multi-racial Le Corbusier-style high rises, named the Christopher Columbus Homes. The tract had contained 8th Avenue, the commercial heart of the neighborhood. Fifteen small-scale blocks were combined into three "superblocks". The Columbus Homes, never in harmony with the rest of the neighborhood, were vacated in the 1980s. They were finally torn down in 1994.
