URBAN GROWTH XIX CENTURY

• Farm productivity increase (less labor producing more output) releases some labor.

• Industrialization (shift from cottage industry to mass production).

• Demographic changes, in particular, migration. • Technological changes in transport and housing

affected density and concentration. • Economic activities, mainly industry, are

centralized and concentrated in the center of the city.

• Urban growth reinforcing itself through the expansion of commercial activities.

PLANNING ISSUES XIX CENTURY

• Public health and sanitation are among the first urban problems planners begin dealing with.

• Open space or parks become a preventive measure of some diseases.

• Housing reform, mainly housing for the poor, also became another planning topic (zoning, housing codes, etc.) .

• Levy describes planning as a fusion of art, architecture, and planning.

PLANNING ISSUES XIX CENTURY

• A breakthrough event that gave planning its very existence is the recognition of establishing some public control over the use of private land.

• Planning started to be seen as a means to deal with issues of interconnectedness and complexity giving as a a result master planning or comprehensive planning.

• Planning little by little becomes a governmental function.

THE CHICAGO PLAN & CIVIC ART

URBAN GROWTH XX CENTURY

• Decentralization forces begin emerging in tandem with improvements in transportation technology (water, railroads, electric cars, combustion engine or Ford’s model T).

• Transportation becomes more flexible and individualized (the density gradient becomes flatter).

• As the country and the population acquire wealth, particularly after WWII, population begins to move to the outskirts of the city and suburbs forming bedroom communities.

URBAN GROWTH XX CENTURY

• Economic activities, such as retail and services, slowly begin to decentralize and deconcentrate from the center. Centrality begins to lose its meaning.

• All of the above could have not been possible without federal programs such as FHA loans, National Defense Highway act of 1956, tax incentives, etc.

• Finally, industry begin to move to the suburbs and the city is transformed from a monocentric to polycentric urban form.

PLANNING ISSUES XX CENTURY • A great shift in the XX century was the acceptance of the

role of government, particularly federal, as a big planner due to the lessons of the Great Depression (TVA, highways & public parks are important examples).

• Dams & other water public works are another important example, particularly, for the Southwest.

• Urban Renewal or poor removal • Highway planning • Municipal planning (suburbanization) • Environmental planning (Late 1960s) • Equity planning (Civil rights movement) • Growth management (1980s) • Smart Growth (1990s) • Smarter growth

SIMILARITIES & DIFFERENCES

EUROPE VS. USA

• How has history influenced the development of cities?

• Why doesn’t Europe have the “problem” of the empty downtown?

• How has Europe approached the issue of housing affordability?

• Why has Europe evolved towards a more environmentally “friendly” policies?

SIMILARITIES & DIFFERENCES

DEVELOPING WORLD VS. USA• What are the key differences of the urban process? What

role does industrialization play? What role does the green revolution play?

• What are the differences in the urban hierarchy of the USA and Mexico? Urban primacy vs. rank size rule.

• How do the XIX century planning issues in the USA compare to the planning issues facing developing nations?

• Are the differences in urban development disappearing or becoming sharper?

• Are megacities such as Mexico City sustainable?

Stages of development(Peter Hall)

• First: rural to urban migration

• Second: Industrialization

• Third: Suburbanization

• Fourth: Deconcentration

• Fifth: Multicentric cities

C. Fuentes• First: the establishment of

the border open the opportunities for commerce & services.

• Second: the surge of maquiladoras (industry) reorganize the urban structure and started competing with commerce & services for location near the bridges.

• Third: the transition from a monocentric to polycentric city.
