CHAPTER 1
What Is a City For?
WHAT IS A CITY FOR? In this urban age, itâs a question of crucial importance but one that is not often asked. Long ago, Aristotle reminded us that the city is a place where people come to live, and they remain there in order to live better: âA city comes into being for the sake of life but exists for the sake of living well.â1
But what does âliving wellâ mean? Is it about accumulating as much wealth as possible? Is it about consuming amenities and collecting the most unique experiences? Is the city a way to reduce the impact of human beings on the environment? Is it about positioning the polisâthe cityâto serve primarily as an engine in the world economy? Is it about establishing the dominion of the powerful and well connected, those persons who can achieve a high quality of life near the urban core? These are the principles that often guide the thinking of most urbanists today.
I start at a different place. If we are to âlive wellâ in the city, it should, first and foremost, address the needs of future generations, as sustainability advocates rightfully state. This starts with focusing on those areas where familiesâthe new generationsâare likely to be raised, rather than primarily focusing on the individual and places where relatively few youngsters grow into adolescence and maturity. We must not forget that without parents, children, and the neighborhoods that sustain them, it would be impossible to imagine how we, as a society, could âlive wellâ or even survive as a species. This is the essence of what I call âthe human city.â
This book is not primarily an argument for any particular urban form. Urban areas now account for 55 percent of the worldâs population, up from 30 percent in 1950.2 These areas range from small towns to suburbs to megacities (cities with populations of over 10 million residents). Most have some unique qualities to offer their residents and provide solutions, economic or otherwise, for them.3 Ideally, urban areas should provide the widest range of living optionsâfrom exurbs and suburbs to a thriving urban coreâthat provide for different people at different stages of life. Living well should not be about where one should live but about how one wants to live and for whom.
Cities, in my definition, are more than what todayâs planners and urban theorists insist they must beâdense and crowded places. To some advocates, these are the only places that matter because they express âsuperiorâ urban virtues pertaining to environmental or cultural values. A few years ago, for example, Seattleâs the Stranger outright scorned the peripheryâwhere âpeople are fatter and slower and dumberââand claimed cities own âa superior way of lifeâ full of âsanity, liberalism and compassionââalthough this compassion hardly seems to apply to those benighted non-urbanites.4
Rather than dismiss the expanding city, we need to include it as part of the contiguous region of settlement, what British authorities call the âbuilt-up urban area.â5 As weâll see, this dispersion is the common reality, more or less, for almost all large cities in the world. Cities are much more than places with arresting architecture or the most attractive places for culture or tourism. Instead, a cityâs heart exists where its people choose to settle. âAfter all is said and done, heâthe citizenâis really the city,â Frank Lloyd Wright suggested. âThe city is going wherever he goes.â6
THE CULT OF DENSITY
Wrightâs observation places emphasis in the right placeâon those who live in the city. People love their places not for general reasons but for specific reasons that relate to their own needs and aspirations. In our contemporary setting, the desires of many citizens often conflict with those of urban planners and consultants. This centers largely on the dominant urbanist notionâwhat may be best called âretro-urbanismââthat cities, in order to be successful, must be made ever denser, much as they were in the late 19th and early 20th centuries. Some, including many New Urbanists, favor doing so on a somewhat human scale, with Paris-style levels of density. Others, influential perhaps more in the developing world, embrace a vision of urban density expressed boldly in high-rise apartment blocks and soaring office towers, which has defined the urban vision ever since high-rise steel frame construction began in late 1880s America.7
Perhaps the most powerful case for the high-rise city was first articulated by the brilliant architect Charles-Ădouard Jeanneret-Gris, also known as Le Corbusier. He envisioned packed buildings surrounded by vast tracts of open land.8 A bold thinker, Le Corbusier was inspired by 1920s and 1930s Manhattan, the city that most approximated his ideal. But Gothamâs many poorer districts and its ramshackle appearance offended him. To him, New York City was not dense enough, its skyscrapers âtoo small.â His goal was to conjure the city as âa miracle of machine civilizationâ with âglass skyscrapersâ that ârise like crystalsâ and serve as âa magnificent instrument for the concentration of population.â9 These cities, he believed, represented the urban future, an idea widely shared, at least broadly, by many urban thinkers today.
Le Corbusierâs work, much of which was written in the late 1920s, epitomized a kind of technological optimism, one that was centered on the application of geometry, mathematics, and mechanics to city building. âA town,â he wrote, âis a tool.â In his vision, cities required âorder,â and that order was necessary if the city was not to âthwartâ its ambitions. His theory was âa struggle against chance, against disorder, against a policy of drift.â
Le Corbusier detested the disorder of the traditional city, its mishmash of building types, its competing densities, and its street-level spontaneity. His was a city of order imposed from above, as had been the case in the earliest times; this order allowed Hellenistic cities to develop in a manner not seen in the cities of early Greece, which also tended to be somewhat haphazard in design.10 Le Corbusier, perhaps not too surprisingly, showed an unseemly admiration for dictators, be they Napoleon III, who rebuilt Paris, or Adolf Hitler, a failed artist who relished massive urban building projects. Like many of todayâs planners, Le Corbusier saw in dense developments the salvation of society. The Corbusian vision of a âcity of skyscrapersâ would allow society to make sufficient economic progress to enhance further the grandeur of the city. 11
Todayâs density advocates are rarely as audacious as Le Corbusier, but they also claim numerous benefits from their sense of a highly centralized urban âorderâ; some organizations, such as the Urban Land Institute (ULI), have been fighting decentralization and suburbanization since the late 1930s.12 There is a widespread notion that higher density will increase productivity, calm the climate, and lower living costs, albeit at the price of homeownership.13 In the following pages, I outline the retro-urbanist argument for each of these purported benefits.
THE ECONOMIC EQUATION
Some retro-urbanists, such as Richard Florida, point to studies such as those from the Santa Fe Institute that show the great productivity of large cities, claiming that âbigger, denser cities literally speed up the metabolism of daily life.â The notion that innovation needs to take place in dense urban settings is now widely accepted. Yet in reality, as the studyâs authors note, their findings were about the population of an area, not the density, and had little to do with the urban form.14
After all, many of the nationâs most innovative firms are located not in downtown cores but in sprawling regions, whether thatâs in Silicon Valley, the north Dallas suburbs, or the âenergy corridorâ west of central Houston. Dense San Francisco proper has seen a significant boom in high-tech-related business services in recent years, yet neighboring San Mateo County still holds more than five times as many jobs in software publishing as San Francisco.15 And despite the recent expansion of tech-related business in San Francisco, the majority of the Bay Areaâs total employment remains 10 miles from the city centerâand is more dispersed than even the national average.16
Likewise, most STEM (science, technology, engineering, and mathematics) employment, a large driver of economic growth, remains firmly in suburbanized areas with lower density development and little in the way of mass transit usage.17 Lower density regions as diverse as Durham, Madison, Denver, Detroit, Baltimore, Colorado Springs, and Albany are among the places with the highest shares of STEM jobs, and in many cases, they are creating new STEM jobs faster than the high-tech stalwarts. Charleston, Provo, Fayetteville, Raleigh, and Des Moines are among the fastest-growing STEM regions since 2001, each with STEM employment up at least 29 percent.18
Much has been written about how large, dense cities are the best places to grow jobs and, increasingly, to find opportunities.19 Yet in reality, the central core has become progressively less important economically, in terms of employment.20 Today, only 9 percent of employment is located in the central business districts, with an additional 10 percent in the balance of the urban cores.21
Americaâs metropolitan areas were largely monocentricâthat is, dominated by the single strong core of downtownâduring the immediate post-World War II period, but since have largely become polycentric. Job dispersion is now a reality in virtually every metropolitan area, with twice as many jobs located 10 miles from city centers as in those centers. Between 1998 and 2006, 95 out of 98 metro areas saw a decrease in the share of jobs located within three miles of downtown, according to a Brookings Institution report.22 The outermost parts of these metro areas saw employment increase by 17 percent, compared to a gain of less than 1 percent in the urban core. Overall, the report found, only 21 percent of employees in the top 98 metros in America lived within three miles of the center of their city. More than 80 percent of employment growth from 2007 to 2013 was in the newer suburbs and exurban areas.23
CITIES, SUBURBS, AND ENVIRONMENT
In addition to economic arguments, claims of environmental superiority also drive the push for densification. Some environmentalists also celebrate the demographic impact of densification, seeing in denser cities a natural contraceptive against population growth, which is seen as a major contributor to environmental destruction. Stewart Brand, founder of the green handbook Whole Earth Catalog, embraces denser urbanization, particularly in developing countries, as a way of âstopping the population explosion cold.â24
Concerns over climate change have been added to justify greater density. âWhat is causing global warming is the lifestyle of the American middle class,â insists New Urbanist architect AndrĂ©s Duany, a major developer of dense housing himself and arguably the movementâs most important voice.25 To advocates such as Duany, a return to old urban forms encourages transit riding over cars, which is one way to reduce carbon emissions.
But besides being environmentally imperative, the shift to denser development is also seen as somehow morally justified. Retro-urbanistsâthose who long for a return to the traditional pre-1950 cityârepresent a kind of moral imperative. Typically, this is cast as a choice between 4,000-square-foot McMansions and unbridled consumption on one side and more sustainable high-density urban living on the other. Columbia Universityâs Earth Institute executive director Steven Cohen speaks of a future âwith smaller personal spaces, more frequent use of public spaces, bikes, parks, high-tech media, and constant attention to oneâs environmental footprint.â26 Prince Charlesâs vision of âeco-citiesââalthough more medieval th...
