Urban Geography
Urban refers to highly developed areas where businesses, people, and industry cluster.
Not limited to big cities….also includes sub-urban areas.
Where are people and activities distributed in urban areas?
What patterns develop in urban areas?
Central Business District (CBD)
Aka “Downtown”
Less than 1% of land area
High % of services, public institutions
High accessibility
Focal point of transportation
Who locates in the CBD?
Retailers w/ high threshold
Ex. Department stores
Now replaced by malls
Retailers w/ high range
Specialists, unique shops
Retailers serving downtown workers
Office supplies, coffee shops, dry cleaning, fast food restaurants
Characteristics of the CBD

High traffic levels.
Chicago
Downtown Traffic
Road and Rail In Chicago
Where is the CBD?
Chicago at Night
Land Use in CBD’s
Land is expensive in CBD’s
Tokyo, London, NYC
High cost of land forces vertical and underground expansion
Skyscrapers
Underground cities
Worlds Most Expensive Land
Cost of Land per square meter 1. Monte Carlo, Monaco –
$47,5782. Moscow, Russia – $20,8533. London, England – $20,7564. Tokyo, Japan – $17,9985. Hong Kong – $16,1256. New York, USA – $14,8987. Paris, France – $12,1228. Singapore – $9,7019. Rome, Italy – $9,16610. Mumbai, India – $9,163
Land in LDC’s might be closer to $3-15 per square meter
Rural land is cheaper than urban land
Not Found in CBD’s
Industry
Have relocated to suburban areas
Old industrial areas (harbors/ piers) are now tourist attractions
Ex. Navy Pier
Residents
Fluctuation: originally rich mansions and crowded apts., then suburbs, now “empty nesters” return in search of nightlife, entertainment, etc.
Skyscrapers
Montreal, Quebec, Canada
Underground Tunnel System in Montrea
Urban Models
3 models, all developed in Chicago
Why Chicago?
Flat (prairie)
Few physical features that interrupt growth (except Lake Michigan)
Predict how cities will develop
Where will different groups of people live in urban areas?
Concentric Zone Model
E.W. Burgess
City grows outward in a series of rings
5 Rings
1. CBD
2. Transition (industry/ poor housing)
3. Working class
4. Better homes
5. Commuters/ suburbs
Concentric Zone Model
Burgess’ Concentric Zone Model
Sector Model
Homer Hoyt
City develops in sectors (sections/ wedges) not rings.
Industry and retail develop along transportation lines
Sector Model
Multiple Nuclei Model
Harris and Ulmann
Multiple nodes (centers) around which activities revolve.
Certain activities choose to locate in certain nodes.
Ex.
Bookstores and bars near college campus
Hotels and warehouses near airport
Multiple Nuclei Model
Dallas TX (Concentric and Sector)
Latin American Model
Wealthiest residents live in CBD and long a commercial spine.
CBD features a market and town square, left over from colonial days.
Sub-Saharan African Model
DeBlij
3 CBD’s
Colonial (vertical)
Traditional (single story shops)
Market Area (open air market)
Satellite townships on the edge.
Informal Settlements
Squatter settlements, favelas (Brazil), townships (Africa), slums, etc.
175 million world wide
Large numbers of people migrate to cities rapidly; cities cannot keep up with growth.
Poorly constructed houses.
Lack basic services: schools, water, electricity, paved roads, sewers.
Mumbai, India
Brazil
Soweto, South Africa
