S5 Geography Urban Land Use, Paper 3: new towns and planning conflicts
Paper 3 works from Hong Kong urban structure and new town aims to land use conflicts, density and population, plot ratio and flat numbers, and finally the link between density and quality of life.
Focus Population is density times area, floor area is site times plot ratio, shares divide by total area, and a plot ratio change scales floor area and flat numbers proportionally.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | High density high rise development, an axis along rail corridors, and core business districts around Victoria Harbour | Steep terrain and scarce flat land push the city upward and along rail corridors, with Central and East Tsim Sha Tsui as core business districts. |
| 2 | Housing next to a container yard, where night time loading noise and heavy vehicles disturb residents | When uses are mixed the external costs of business fall on nearby households, so planning separates noxious uses. |
| 3 | 204 000 people | Population is density times area, and 24 000 times 8.5 is 204 000. |
| 4 | To decentralise population, provide local jobs and supply a full range of community facilities | New towns aim at self containment so residents can work and use schools and hospitals locally, cutting cross district travel. |
| 5 | 18 000 square metres | Floor area is site area times plot ratio, so 2400 times 7.5 is 18 000. |
| 6 | 6500 km | Twenty six times 250 is 6500, and long journeys add to traffic pressure and emissions. |
| 7 | 15 per cent | Fourteen point four over ninety six times 100 is 15 per cent. |
| 8 | About 33.3 per cent denser | Thirty six thousand over twenty seven thousand is 1.333, so A is about a third denser. |
| 9 | 1600 flats | Floor area scales with plot ratio, and 8 over 5 is 1.6, so 1000 times 1.6 is 1600. |
| 10 | High density with good transport, parks and community facilities can still support a good quality of life, so per capita space and provision must be judged together | Density is only one indicator, and planning quality and facilities matter as much. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
