Chapter 13 sections 1, 2 and 9 Central Business District, Models of Urban Structure and Sprawl
Terms/Concepts • Central Business District • Concentric Zone Model • Sector Model • Multiple Nuclei Model • Peripheral Model • Sprawl
Explaining the City • Cities are ever changing but sociologist, economist, and geographers try to develop models to explain them • Not all models apply to all cities and cities may actually be a combination of many models
Central Business District • Central business district (CBD) • Best-known and most visually distinctive area of most central cities • AKA “downtown” • Usually one of the oldest districts in the city • Original site of the settlement • Visually distinct • Is the easiest part of the city to reach from the rest of the region (accessibility) • Focal point of region’s transportation network
Concentric Zone Model • Concentric Zone Model- city grows outward from a central area in a series of five concentric rings • 1. Central Business District (CBD) • 2. Zone of Transition • Industry and poorer quality housing • 3. Zone of independent workers’ homes • Modest houses occupied by stable, working-class families • 4. Zone of better residences • Mores spacious homes for middle-class families • 5. Commuter’s zone • Work in the center choose to live outside the city
Sector Model • Sector Model- city develops in a series of sectors or wedges that radiate out from the central business district
Multi-Nuclei Model • Multi-Nuclei Model- social groups are arranged around a collection of nodes of activities • Cities are complex and include more than one center around which activities revolve • Some activities are attracted to particular nodes while others are not
The Peripheral Model • Peripheral Model- consists of an inner city surrounded by large suburban residential and business areas tied together by a beltway or ring road • Has led to sprawl – progressive spread of development of new housing sites over the landscape
Important points regarding models • Human geographers have developed tools for describing cities • These models focus on different types of urban land use and their locations relative to the CBD • There are different models, but they contain many similar elements • Urban land use has changed since the models were developed and continue to change today • The models may need to be adjusted in order to reflect current land use in urban areas
