Chauncey Harris’ Peripheral Model• Peripheral Model (similar to Urban Realms)

– Urban area =• Inner CBD • Suburbs (different income levels) surround CBD (these suburbs turn into..?)• Offices, malls, etc. mixed in to service people• All tied together by “BELTWAYS”

• Density gradient (amount of land & people on it) decreases as distance from CBD increases

- extensive v. intensive• Benefits from suburban life?

– Less crime– Better education– More individual space (large house, yard, garage)– Less traffic

• Problems?– Urban sprawl– Creates segregation (zoning laws)

Peripheral Model of Urban Areas

The central city is surrounded by a ring road (beltway), around whichare suburban areas and edge cities, shopping malls, office parks,

industrial areas, and service complexes.

Urban Styles Around the WorldAmerican v. European cities

– Rich Americans → suburbs– Rich Europeans → CBD w/ rural country homes

– Poor Americans → city in low density, dispersed government housing (less funded over time)

– Poor Europeans → “high density” suburbs near the city (high-rise subsidized housing - concentrations of poor people create MAJOR problems)

– Only 2% of USA in government housing; More of Europe (30%)

Peripheral Urban Areas• Most LDCs put poor in suburbs & rich in CBD • Griffin-Ford (Latin American) Model = CBD with

wheel-like spokes• Often grid-like organization with central plaza &

boulevard (Spanish influence)• Squatter settlements (a.k.a. favela, barrio, slum,

shantytown, bustee, kampongs,…“disamenity sector”) in suburbs start as illegal, temporary squatters on the periphery/city’s edge – 2009 FRQ
