The Atlanta BeltLine transforms the city’s landscape with a pedestrian-friendly environment, but the public concern over the resulting gentrification has only grown since the megaproject began. In response, the city intends to mitigate any threat of its residents’ displacement with affordable housing policies – one of which is an inclusionary zoning ordinance. This study aims to identify the extent to which Atlanta’s inclusionary zoning policies to provide affordable housing. The study is based on the proposition that, to reduce the social cost of relocation, it is preferable for affordable housing to be located near neighborhoods that are either gentrifying or vulnerable to gentrification. To understand the relationship between gentrification and affordable housing in Atlanta, I developed a system for identifying the stages of gentrification. To validate my system, I compared it with the widely used identification system developed by the Urban Displacement Project. I then conducted an ordinary least squares regression analysis using these stages with the affordable housing locations as variables. The results confirmed the expansion and intensification of gentrification since construction on the BeltLine began, and in which that construction has played a critical role. The location of the city’s affordable housing showed no significant relationship with either gentrifying neighborhoods or those vulnerable to gentrification. These results further demonstrate that Atlanta’s policy for increasing its affordable housing inventory fails to pursue the public good or to mitigate gentrification by reducing the cost of relocation for displaced residents. The study concludes that supplementary policies are required to protect susceptible populations from gentrification.
