PLAN261 Lecture Notes - Lecture 5: Federal Housing Administration, Concentric Zone Model, Urban Sprawl
Document Summary
The classic industrial city (1850-1945) has a concentric zone model, consisting of a central business district (cbd), surrounded by factory/warehousing zone, working class communities, middle class suburbs, all connected by railways. The working class is closer to the cbd because they can"t afford transportation. Ww2, so the zones are wider, there is some restructuring, and more transportation. There are new urban centres, deindustrialized services, and an urban beltway. The post-industrial city (1975-current) has more restructuring, some decline (income, socio-economic status of some residents), gentrification, diversification, and suburbs (ethnic, economic status, industrial). There are shopping centres and edge cities (usually offices). The us and canada use land ineffectively (dispersed urban form). Some cities consume more land (eg: pittsburgh, us). Also, santiago (1890-2002) had a huge increase in urban sprawl in 1920 due to the vehicle. Since ww2, north american cities went through radical change.
