Guide expansion toward safe, serviced and connected places before unplanned costs become permanent.
This page turns the subject into a public problem-solving framework: place, problem, causes, evidence, solutions, roadmap, results and contribution.
What is failing, for whom and where?
02 · Development enters floodplains or ecologically sensitive areas.
03 · Low-income households are pushed to distant, poorly connected land.

| Evidence area | What to establish | Key limitation |
|---|---|---|
| Growth | Population, household and employment scenarios | Forecasts should use ranges |
| Land | Ownership, use, vacancy and constraints | Records require ground checks |
| Capacity | Existing and funded infrastructure | Proposed capacity may be delayed |
| Access | Jobs, transit and services by travel time | Distance is not accessibility |
| Risk | Flood, heat, water stress and ecology | Historical maps may understate future risk |
