Walkers in the City

The Center for Real Estate and Urban Analysis at The George Washington School of Business has released Foot Traffic Ahead: Ranking Walkable Urbanism in America’s Largest Metros for 2016. The Executive Summary opens,

The end of sprawl is in sight. The nation’s largest metropolitan areas are focusing on building walkable urban development.

For perhaps the first time in 60 years, walkable urban places (WalkUPs) in all 30 of the largest metros are gaining market share over their drivable sub-urban competition—and showing substantially higher rental premiums.

This research shows that metros with the highest levels of walkable urbanism are also the most educated and wealthy (as measured by GDP per capita)— and, surprisingly, the most socially equitable. (4)

This strikes me as a somewhat over-optimistic take on sprawl, but I certainly welcome the increase in walkable urban places over a broad swath of metropolitan areas. The report’s specific findings are that

There are 619 regionally significant, walkable urban places—referred to as WalkUPs—in the 30 largest U.S. metropolitan areas. These 30 metros represent 46 percent of the national population (145 million of the 314 million national population) and 54 percent of the national GDP.

The 30 metros are ranked on the current percentage of occupied walkable urban office, retail, and multi-family rental square feet in their WalkUPs, compared to the balance of occupied square footage in the metro area. The six metros with the most walkable urban space in WalkUPs are, in rank order, New York City, Washington, DC, Boston, Chicago, San Francisco, and Seattle.

Economic Performance: There are substantial and growing rental rate premiums for walkable urban office (90 percent), retail (71 percent), and rental multi-family (66 percent) over drivable sub-urban products. Combined, these three product types have a 74 percent rental premium over drivable sub-urban.

Walkable urban market share growth in office and multi-family rental has increased in all 30 of the largest metros between 2010-2015, while drivable sub-urban locations have lost market share. The market share growth for 27 of the 30 metros is two times their market share in 2010. This is of the same or greater magnitude as the market share gains of drivable sub-urban development during its boom years in the 1980s, but in the reverse direction.

Indicators of potential future WalkUP performance show that many of the metros ranked highest for current walkable urbanism are also found at the top of our Development Momentum Ranking—namely, the metros of New York City, Boston, Seattle, and Washington, DC. This indicates that these metros will continue to build on their already high WalkUP market shares and rent premiums.

There are also some surprising metros in this top tier of Development Momentum rankings, including Detroit, Phoenix, and Los Angeles.

The most walkable urban metro areas have a substantially greater educated workforce, as measured by college graduates over 25 years of age, and substantially higher GDP per capita. These relationships are correlations, and determining the causal relationships requires further research to prove.

Walkable urban development describes trends resulting from both revitalization of the central city and urbanization of the suburbs. For nearly all metros, the future urbanization of the suburbs holds the greatest opportunity; metro Washington, DC, serves as a model, splitting its WalkUPs relatively evenly between its central city (53 percent) and its suburbs (47 percent).

Social Equity Performance: The national concern about social equity has been exacerbated by the very rent premiums highlighted above, referred to as gentrification. Counter-intuitively, measurement of moderate-income household (80 percent of AMI) spending on housing and transportation, as well as access to employment, shows that the most walkable urban metros are also the most socially equitable. The reason for this is that low cost transportation costs and better access to employment offset the higher costs of housing. This finding underscores for the need for continued, and aggressive, development of attainable housing solutions. (4, footnote omitted)

There is a lot of import here. Is there more than a correlation between walkability and the educational level of the workforce and, if so, why? Why don’t more housing affordability studies take into account transportation costs when evaluating the affordability of a given community? What is the trend line of this new direction toward urbanism and how far can it go in the face of decades of investment in car-based communities? This annual study will help us answer those questions, over time.

Zoning Rules and Income Inequality

William Fischel, a preeminent land use scholar, has recently published Zoning Rules!: The Economics of Land Use Regulation. The abstract for the book reads,

Zoning has for a century enabled cities to chart their own course. It is a useful and popular institution, enabling homeowners to protect their main investment and provide safe neighborhoods. As home values have soared in recent years, however, this protection has accelerated to the degree that new housing development has become unreasonably difficult and costly. The widespread Not In My Backyard (NIMBY) syndrome is driven by voters’ excessive concern about their home values and creates barriers to growth that reach beyond individual communities. The barriers contribute to suburban sprawl, entrench income and racial segregation, retard regional immigration to the most productive cities, add to national wealth inequality, and slow the growth of the American economy. Some state, federal, and judicial interventions to control local zoning have done more harm than good. More effective approaches would moderate voters’ demand for local-land use regulation—by, for example, curtailing federal tax subsidies to owner-occupied housing.

The book engages with many other leading land use scholars like Edward Glaeser, Robert Ellickson and Vicki Been so the reader gets a good sense of what is at stake in contemporary land use debates.

I was particularly intrigued by Fischel’s discussion of the relationship between land use policies and income inequality. He writes that, “Moving to opportunity was an important source of income equalization for the first two-thirds of the twentieth century. That migration trend has nearly stopped as a result of increased land use regulation in the high-productivity areas” on the coasts. (166-67). The book carefully parses out how such changes in land use regulation had such a big effect on people’s choices.

Too Many Parks?

Robert Ellickson has posted Open Space in an Urban Area: Might There Be Too Much of a Good Thing? to SSRN. The abstract reads,

Numerous policies encourage the preservation of open space in urban areas. Two of many examples are large-lot zoning and tax benefits to donors of conservation easements. These policies rest on the plausible inference that an open space can benefit nearby residents, for instance, by enhancing scenic vistas and recreational opportunities. But commentators tend to underestimate the costs of open space. The key advantage of urban living is proximity to other people. Open spaces reduce urban densities, increase commuting times, and foster sprawl. I advance the heretical view that a metropolitan area can suffer from having too much open space, and briefly suggest some reforms, particularly in zoning and conservation-easement policy.

This brief essay is thought-provoking, particularly for those of us in NYC. Mayor De Blasio is embarking on an ambitious plan to build or preserve 200,000 units of affordable housing and there are all sorts of land use debates raging over the appropriate level of density in the city. This essay suggests that we should model the costs and benefits of open space in order to work toward a more optimal amount of it in each community. As Ellickson notes, “Development displaced by the setting aside of open space could be pushed in one of three directions: toward the center city, toward the periphery, and beyond the region in question.” (8) This dynamic plays out differently in a city that is built up as much as NYC. But it is reflected in our discussions about density: low density in the central city pushes development outward, one way or another.

Ellickson’s insights are also relevant to the analysis of the overall land use regimes of broader regions: “Open space provides essential relief from urban asphalt and concrete. But debates over the merits of open space tend to understate the opportunity costs and negative externalities of protecting land from development.” (19) He argues that the archetypal bedroom community near NYC is “ideally situated to house commuters. Its large-lot zoning and unstinting acquisitions of open space have contributed to the further sprawl of Greater New York. There can be too much of a good thing.” (19) The essay does not give too much guidance as to how regions such as Greater New York can best address these issues, but it does raise important questions that policy makers should seek to answer.
