Sustainable for Whom? Large-Scale Urban Development Projects and 'Environmental Gentrification'
Large, adaptive-reuse, "sustainable development" projects are all the rage these days in urban planning circles. These are projects where large pieces of abandoned or underutilized infrastructure are repurposed as centerpieces of major urban redevelopment initiatives that are couched in the rhetoric of sustainable development.
They bring positive environmental amenities to an area, including added green space, increased walkability and bicycle-friendliness, and more local shopping and retail services.
These projects are often led by local governments or their affiliate agencies and tend to involve substantial public and/or philanthropic subsidy. Examples range from New York’s High Line, to Washington, DC's 11th Street Bridge project, to Chicago's 606 Trail.
Over the last twelve years, I have studied and closely monitored one such project, the Atlanta BeltLine, and drawn some lessons from the project, particularly for cities or regions where, overall, the housing market is strong. (These lessons do not apply directly to large-scale projects in cities with declining populations or “weak market” cities. In such cities, home values and rents are likely to be stagnant or declining, and large-scale redevelopment projects that improve the desirability of declining neighborhoods are more likely to be handled without large-scale affordability problems. This is not to say that gentrification or displacement cannot occur in pockets of weak-market cities, but the scale and speed of such change is likely to be more limited.)
I have come to the conclusion that, absent a fundamentally new approach to redevelopment planning that places housing affordability at the center of the process, large-scale sustainable development projects are likely to become engines of what has been termed “environmental gentrification.”
The Atlanta BeltLine will ultimately connect 45 Atlanta neighborhoods via a 22-mile loop of trails, parks, and eventually a planned streetcar, all of which will follow abandoned railroad tracks that encircle Atlanta. According to Atlanta BeltLine, Inc., the quasi-governmental agency that is building and administering the BeltLine, as of 2016 the project consists of “four open trails; two trails under construction; seven parks; intensive planning for modern streetcar expansion; more than $3 billion in private economic redevelopment; hundreds of affordable workforce homes; free fitness classes; a linear arboretum; an urban farm; and the largest temporary public art exhibition in the South.
The BeltLine is being financed by a mix of public sector financing and corporate and foundation philanthropy, at the heart of which lies tax increment financing (TIF). As the BeltLine’s principal funding mechanism, the TIF redirects increases in property tax revenues that arise after its establishment to project-related expenses rather than to the regular general revenue budgets of the city, county, or school district. The duration of the TIF in this case is 25 years, which spans from 2005 when it was adopted to 2030 when the project is expected to be fully completed.
Projects like the BeltLine have the power to transform communities so rapidly and dramatically that they call for a new approach to planning and implementation that I call “Affordability First.”
