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.
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.
