1. Definition of Urban Sprawl • From: Suburban Nation: The Rise of Sprawl and the Decline of the American Dream: “An abstract system of carefully separated pods of single use. Daily needs are located within driving distance…”
2. The Components of Urban Sprawl • Five strictly segregated components of sprawl: • Housing subdivisions (“clusters” or “pods”; exclusively residential; income segregated) • Shopping centers (“strip centers,” “malls,” “power centers,” “big box retail”) • Office parks (“business parks’; workplaces only, isolated from other uses) • Civic institutions (“community “centers,” but surrounded and isolated from urban fabric by parking lots: everybody must drive to them) • Roadways (transportation space: streets & parking now the 2nd largest consumer of land in American metro areas after residential)
3. Leapfrog Development • Leaving behind undeveloped parcels of land as development takes place farther and farther out from the center • Development is discontinuous • Impacts: Excessive travel, air pollution, wasted time, loss of sense of community • Zoning may almost mandate such patterns • Land is often held for speculative purposes
