On Big Beaver Road: Detroit and the Diversity of American Metropolitan Landscapes Robert Fishman A century ago each major metropolitan region in the United States had its own distinctive landscape—its unique synthesis of geography and regional building types. From the tenements and brownstones of New York, to the four-flats and bungalows of Chicago, to the wood-framed “painted ladies” of San Francisco, American cities gloried in the small-scale, craft-oriented building industries and localized systems of finance that built their unique identi- ties. At the same time, however, overall regional form was, within the limits of differing geographies, surprisingly uniform, as American metropolitan regions converged around the model of the “centralized industrial metropo- lis” most clearly expressed in Chicago. Every major met- ropolitan region possessed (or aspired to possess) a version of Chicago’s Loop or central business district, surrounded by a “factory zone” with worker’s housing, and finally a small but prosperous “suburban ring.” Today, we are in the opposite position: building types are stultifyingly similar nationwide, yet the overall forms of metropolitan regions have become surprisingly diverse. This new combination of similarity and difference makes it difficult to “read” American metropolitan land- scapes today. It is all-too-easy to perceive nothing but undifferentiated sprawl—the coast-to-coast recurrence of Christopher Leinberger’s “nineteen standard real estate product types,” spread over an equally-standardized low- density, fragmented, automobile-dependent landscape. 1 But the very pervasiveness of this sprawl tends to hide vastly differing landscapes at the metropolitan scale. For example, a recent study of average regional densities ranked New York and Los Angeles as our two densest regions—but, of course, for opposite reasons. New York still possesses the older pattern of a sharply falling “density gradient,” whereas Los Angeles has only recently filled in to a relatively constant density over a vast urbanized area. 2 Similarly, a recent study of “job sprawl” paired Detroit with Tampa-St. Petersburg-Clearwater as two notable examples of “extremely decentralized employment metros.” But, again, the causes are starkly different. Both earn their designation as “extremely decentralized” by having only 5 percent of their jobs within three miles of the regional core, and more than 75 percent of the jobs ten miles or more from the core. But where Tampa-St. Peters- burg-Clearwater was “built decentralized,” with recent explosive job growth spread out through an extended region, Detroit as late as 1950 expressed even more strik- ingly than Chicago the basic form of the centralized industrial metropolis, with more than three-quarters of the region’s jobs and population tightly concentrated in the central city. Half a century of “urban crisis,” however, has devastated Detroit’s downtown and depopulated and dein- dustrialized its vast, once-thriving “factory zone,” so that more than three-quarters of the remaining jobs are now located outside the central city. 3 The Divided Metropolis In this kaleidoscope of metropolitan landscapes, Detroit has the melancholy distinction of faithfully following into the twenty-first century the “urban crisis” trajectory that seemed the fate of all older American cities in the 1960s and 1970s. In spite of continuous large-scale private/public investment downtown—ranging from a John Portman- designed massive hotel/office complex called the Renais- sance Center (1978), to a constantly expanding convention center, to new baseball and football stadiums, to four new gambling casinos—the Detroit downtown remains largely derelict, a landscape of abandonment that led photog- rapher Camilo Vergara to call for preserving it intact as a “national ruins park.” 4 Even worse is the surrounding factory zone, where the brownfield landscape is unparal- leled nationwide in its size and devastation. These zones of abandonment stretch almost uninter- ruptedly from downtown to the city line, making the famous “8 Mile Road” a more salient border for the region than the nearby international boundary between the United States and Canada. What this border expresses most clearly is that Detroit is the most segregated of American metro- politan regions: crossing 8 Mile means going from a central city that is 87 percent black to neighboring white working- class suburbs that are less than 2 percent minority. 5 Pros- perity also suddenly appears—both the well-maintained tract houses of highly paid automobile workers (the “blue- collar aristocracy”) in Macomb County, and the more sub- stantial affluence of neighboring Oakland County, where such suburbs as Birmingham, Troy, and Bloomfield Hills are among the wealthiest in the nation. Although the city of Detroit has declined from a peak population of nearly 2 million in 1950 to 850,000 today, the region as a whole has never shrunk, and is now home to more than 4 million people. Yet no other metropolitan region in the developed world perhaps shows so stark a pattern of concentrated poverty and concentrated affluence. 6 Although there is no single explanation for the hyper- intensity of Detroit’s divided metropolis, I would identify at least two elements that distinguish it even from other Rustbelt regions. Detroit’s sudden rise from a second- ary city in the late nineteenth century to world leadership only thirty years later as “the Motor City” meant that its Fishman / On Big Beaver Road

Imitation des enseignants

Ni prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
