In 1993, Atlanta received one of the first grants awarded by the federal HOPE VI program—which aimed to knock down the most decrepit public-housing projects in America and replace them with better housing—to demolish and rebuild the Techwood Homes. The demolitions took place just before the city hosted the 1996 Summer Olympics. If you went to Techwood’s site today—sandwiched between Georgia Tech and the Coca-Cola museum—you would see a commemorative plaque but almost none of the original brick buildings that fell into dilapidation. Instead, you would find yourself in Centennial Place, a mixed-income community with subsidized apartments alongside private, market-rate housing. It was intentionally designed to reduce the isolation of the urban poor—and it’s succeeding.
