Urban shrinkage has been the subject of extensive attention within the planning community, especially so in light of recent projections that global population will soon reach sustained decline. In the United States, a relatively large number of cities and regions have experienced increased distress over the past two decades, according to measures relating to population and economic decline, or vacant and abandoned housing. But with overall immigration on the wane and birthrates at record low levels, the problems associated with falling populations have suddenly become a concern for planners everywhere. Population decline can significantly reduce the quality of life for residents: extreme examples include severely degraded infrastructure in Flint, MI and social unrest in Baltimore, MD.

The following collection of excerpts, mostly from the book's first chapter, are reprinted with permission of the authors and the publisher.

Hope for Shrinking Cities

The cover of the book Supporting Shrinkage: Better Planning and Decision-Making for Legacy Cities.The good news is that there are opportunities to address municipal decline issues by using tools of planning and policy design that take advantage of recent innovations in data analytics and information technology. We are talking about prospective and prescriptive analyses. These are intended to provide stakeholders with specific, evidence-based responses using principles of decision sciences applied to spatial data. These responses are rooted in principles of inclusion, engagement, empowerment, and advocacy with, by, and for localized and traditionally underrepresented communities. In our new book Supporting Shrinkage: Better Planning and Decision-Making for Legacy Cities (SUNY Press), we present, with our co-authors, promising examples of data-driven decision making for shrinking cities and distressed communities, and hint at new applications that can leverage data and technology for greater positive impacts. We argue that decisions informed by qualitative and quantitative data and analytic methods, implemented through accessible and affordable technologies, and based on notions of social impact and social justice, can enable residents to play a leading role in the positive transformation of their distressed communities.

The Baltimore Experience

As the U.S. was emerging from the Great Recession in 2013, Maryland received $550 million from the General Mortgage Servicing settlement of a lawsuit against the nation’s five largest mortgage servicers for abuses associated with foreclosure abuses, fraud, and unethical mortgage servicing practices (Maryland Attorney General, undated). The city of Baltimore used $10 million of these funds to support efforts towards acquisition and demolition of 4,000 blighted properties, resident relocation and homeowner down payment assistance under the Vacants to Value (V2V) program. 

To gain insight into the process by which planners decided which vacant properties to acquire and demolish, our research team used a Community-Based Operations Research approach to develop a computer model to model the values that the city’s team brought to their task and then interviewed them about their decision-making. 

We learned that the overriding concern for planners was the level of distress across the neighborhoods, and the primary decision-making conflict was between targeting money toward revitalizing one area versus spreading the funds more equitably across the city emerged as a theme within the development of action plans while working with a limited budget. Some City officials expressed the opinion that targeting funds in a more strategic manner would have a larger impact, while others emphasized the importance and political necessity of the equitable distribution of demolition dollars across the city.

Based on the interviews we conducted, the City’s criteria for this selection process seemed to center around the themes of blight elimination, neighborhood stability, support of existing redevelopment efforts, large-scale demolition, targeted investment, and equal distribution of funds across the city. Using decision modeling methods, we generated a range of vacant parcel re-use strategies that balance competing objectives and provide planners with multiple development alternative strategies that provide a basis for conversations with community stakeholders.

Lessons for Supporting Shrinkage

The development of a model for improving decision-making in Baltimore (and elsewhere) proved key and can be more broadly generalized to other communities addressing shrinkage. Decisions regarding housing and community development informed by analytic planning models, and planning support systems based on these models, can and should reflect the perspectives of multiple stakeholders, facilitate active participation across diverse groups, address a wide variety of active and passive land uses, and be rooted in principles of inclusion, engagement, empowerment, and advocacy. Such planning methods and technologies have the potential to transform our notion of what more widely available data and smart cities can do with and for shrinking cities, declining regions, and distressed communities. But for shrinking cities to take advantage of these methods, they will need a commitment to community engagement, good governance, and appropriate technical expertise.
