Title: Urban Sprawl in North America: Where Will It End


1
Urban Sprawl in North America Where Will It End?
  • Chapter 5

2
I. Geoterms
  • A. Metropolitan Area a major population center
    made up of a large city and the smaller suburbs
    and towns that surround it.
  • B. Rural Fringe the small towns, farms, and open
    spaces that lie just beyond a citys suburbs.
  • C. Suburb a developed area at the edge of a city
    that is mainly homes. Many suburbs also have
    stores and businesses.

3
  • D. Urban Core the older part of a big city.
    Often the urban core serves as the downtown or
    central business district of a city.
  • E. Urban Fringe the ring of small towns and
    suburbs that surround a big city.
  • F. Urban Sprawl the rapid, often poorly planned
    spread of development from an urban area outward
    into rural areas.

II. The Geographic Setting
  • A. The Old Walking City The Urban Core
  • 1. Urban Core started during colonial times. This
    is the heart of the town (Downtown) where people
    could walk from their home to businesses.
  • 2. 1890s, street cars and trains were developed
    and people began to live further away and commute
    into the city. People moved outward along rail
    lines.

5
  • B. Suburbs Around the City The Urban Fringe
  • 1. 1920s, cars were using paved roads so people
    didnt have to live along rail lines.
  • 2. Common use of cars allowed housing farther
    away from the urban core. Suburbs ringed cities
    forming an urban fringe.
  • 3. Old city cores decayed as people and
    businesses moved out and started new town centers.

6
  • C. Where City Meets Country The Rural Fringe
  • 1. Rural Fringe is where there are farms, open
    space, and fewer people.
  • 2. These areas grow and urban sprawl begins.

7
III. The Case for and Against Urban Growth
  • A. Urban Growth Creates Needed Homes
  • 1. Rural land is cheaper and building homes here
    is less expensive
  • 2. People usually believe it is better to raise a
    family in the suburbs
  • 3. New construction creates jobs. New homes
    require purchases.
  • 4. More taxes are paid to the government for the
    infrastructure.

8
  • B. Urban Sprawl Damages the Environment
  • 1. New homes take away animal and plant habitat
  • 2. Urban sprawl creates pollution from more cars
    and waste

9
IV. Portland, Oregon, 1973
  • A. Growth Threatens the Willamette Valley
  • 1. Willamette Valley known for roses, farms, and
    orchards
  • 2. Portlands growing population and urban sprawl
    would destroy this environment.

10
  • B. Difficult Decision How Best to Grow?
  • 1. The state looked at several options. One
    option was to allow urban growth to continue, but
    for each acre developed, the state would require
    that another acre be set aside to be preserved as
    open space
  • 2. A second option was to not allow any more
    building to go on
  • 3. A third option allowed growth, just not in the
    Willamette Valley

11
V. Portland Plans for Smart Growth
  • A. Urban Growth Boundaries Limit Sprawl
  • 1. Urban Growth Boundaries
  • A. A legal border that separates urban land from
    rural land
  • B. Growth is allowed in the borders, but not in
    the rural area
  • 2. Metro was developed as a regional government
    to plan the growth within the boundaries.

12
  • B. Mixed Use Helps Portland to Grow Up, Not Out
  • 1. Today, Portland is a compact,
    controlled-growth area
  • 2. Public transit system (buses, streetcars)
    reduce the need to drive
  • 3. Mixed-use developments allow for mixed housing
    and business (apartments above a store)
  • 4. Advocates of the program say people drive
    less, thus less pollution
  • 5. Opponents say people cannot find large homes
    on big lots, thus not meeting the desires of the
    people

13
VI. Toronto, Ontario, 1999
  • A. Building Up and Filling In Limits Sprawl
  • 1. Toronto has a long history, so by 1960s, the
    urban core was run down
  • 2. 1965, Toronto started Infill where old urban
    core is rebuilt and empty space is filled in
    instead of sprawling out.
  • 3. By the 1970s, Toronto rebuilt itself into a
    modern city

14
  • B. Rapid Growth on Torontos Rural Fringe
  • 1. By 1990s, urban sprawl took over farmland,
    forests, and wetlands.
  • 2. Traffic increased and so did the pollution
  • 3. They considered various plans (mixed-use
    development, ban all growth in rural areas, limit
    growth only to certain areas)

15
VII. Toronto Plans for 30 Years of Growth
  • A. Planning for Future Growth
  • 1. The Official Plan allowed growth in 25 of the
    city
  • 2. It allowed growth in the old urban core and on
    the waterfront.
  • 3. Public transportation was to be expanded
  • 4. Mixed-use and infill were to be developed

16
  • B. Concerns About Infill
  • 1. Developers said it was too costly because they
    had to clean up the old before building new.
  • 2. Current residents of the urban core felt that
    it would become too crowded

17
VIII. Atlanta, Georgia, 1998
  • A. Rapid Growth Leads to Traffic Jams
  • 1. 1990s, Atlanta metropolitan area led the USA
    in urban sprawl
  • 2. Animal and plant habitat was being destroyed
  • 3. Residents drove more miles every day than
    drivers anywhere else in the world

18
  • B. Air Pollution Threatens Highway Funds
  • 1. Air pollution increased
  • 2. Respiratory ailments increased
  • 3. Atlanta violated the federal Clean Air Act and
    was in jeopardy of losing federal highway funds.
  • 4. Various options were studied

19
IX. Atlanta Fights Pollution with Public Transit
  • A. A Regional Transportation Authority was
    created
  • 1. Focus was on public transit
  • 2. Three goals were stressed
  • A. Reduce traffic jams
  • B. Reduce the amount of air pollution from cars
  • C. Reduce poorly planned development

20
  • 3. They encouraged people to get out of their
    cars
  • A. Encourage people to walk to shops and jobs
  • B. Encourage people to walk or bike through new
    bike trails and walking paths
  • C. Built new rails, subways, and bus lines

21
  • B. Atlanta Continues to Grow
  • 1. Atlanta now meets federal air-quality
    standards
  • 2. Urban sprawl still occurring
  • 3. Pollution still a problem
  • 4. Water supply a concern
  • 5. Mixed-use development taking place
  • 6. New homes in rural areas still being built

22
X. Beginning to Think Globally
  • A. Cities Continue to Sprawl
  • 1. USA and Canada still growing
  • 2. Need for housing still growing
  • 3. Concerns for the environment still present
  • B. Sprawl is a Worldwide Problem
  • 1. More people moving to cities, needing housing
  • 2. Mumbai is good example

23
XI. Global Connection
  • A. Why might some regions have more metropolitan
    areas than others?
  • B. Why are there so many cities with more than 5
    million people in Asia?
  • C. What special problems might urban sprawl
    create for poor countries?
