In 1990, Atlanta was selected to hold the 1996 Summer Olympics. This led many city leaders to become concerned about the state of public housing in the city, at a time when HUD had labelled the AHA one of the worst housing authorities in the nation. On the national level, concerns about the state of public housing had led Congress to appropriate funds for HOPE VI, a program designed to revitalize public housing. In 1993, Atlanta won the first HOPE VI grant to renovate and modernize Techwood and Clark Howell Homes. At first, the idea of replacing public housing with mixed-income housing was not considered, and the entire project was to remain public housing. The Integral Group and McCormack Baron Salazar together won the contract in 1994 to demolish Techwood and build its replacement, Centennial Place. By the opening of the 1996 Olympics Techwood had been demolished, although visitors were able to tour a virtual exhibition of the project. When Centennial Place opened, the concept had changed to that of a mixed income community, with only 300 of the previous 1100 units remaining for low-income residents.
