Compact city with corridors/green wedges
Long-range growth with environment focus
Perth and Peel@3.5million, issued by the Western Australian Planning Commission in 2018, is a long-range framework for accommodating a metropolitan population of 3.5 million. Its key moves are consolidation of growth within a defined urban footprint, intensification around rail corridors and activity centres, and protection of green wedges and environmentally sensitive lands, elaborated through sub-regional frameworks. It is paired with strategic environmental assessment of the region's bushland and water systems.
The framework marks Perth's attempt to break with one of the most dispersed, car-dependent growth patterns of any Australian city, continuing a lineage of metropolitan strategies from the 1955 Stephenson–Hepburn plan onward. Its coupling of urban consolidation targets with region-scale environmental assessment has been noted as an Australian innovation. Debate persists over whether infill targets are achievable against entrenched greenfield development interests.
