11 (a) Outline the characteristic functions of the Central Business District (CBD). 
(b) How would you collect and record information about land-use in the CBD, when doing fieldwork in an urban area? 
(c) Assess the possible advantages and disadvantages for shops (retail outlets) of locating near the edges of urban areas rather than centrally.
5 Fig. 5 shows the planned layout of the central area of Portland, Oregon, USA. In 2006 the city’s total population was 563 000.
(a) Compare the character of land-use on the two sides of the Willamette River. 
(b) New residential development is occurring at the location marked X on Fig. 5, with the conversion of a disused warehouse into high quality apartments.
Outline the possible advantages and disadvantages of living at X, using the information in the figure and your knowledge of urban areas. 
6 Fig. 5 shows settlement dynamics in the city of Chicago and its region, USA, in 2005.
(a) Describe the location of the areas of decline shown in Fig. 5. 
(b) Compare the location of the areas of slow growth and of expansion growth in Fig. 5. 
(c) Suggest reasons why Chicago is growing in the areas shown in Fig. 5. 
12 (a) (i) Describe briefly the character of retailing (shops) in the Central Business District (CBD) of large urban areas. 
(ii) Give two reasons why there may be little residential population in central areas of cities. 
(b) Describe one or more developments in a large urban area you have studied and suggest reasons why they occurred. 
(c) Assess the success of one or more attempts to provide infrastructure (such as transport, power supply and water supply) for a city you have studied. 
11 Study Fig. 5, which shows possible changes over time in land values in an industrial city in an MEDC.
(a) Describe the changes in the relationship between land value and distance from the CBD shown on Fig. 5. 
(b) Suggest reasons why land in zone S increases in value during the declining industrial stage.
Use examples to support your answer. 
(c) To what extent do you agree that re-urbanisation (movement back to live in inner urban areas) has much to offer to people?
