Abstract

Infrastructure systems are critical to support sustainable and equitable urbanisation, and infrastructure is becoming more prominent within urban spatial strategies. However, the fragmented governance and delivery of spatial plans and infrastructure projects create a challenging environment to embed planning goals across the planning, delivery and operation of infrastructure systems. There is significant uncertainty around future needs and the complex ways that infrastructures influence socio-spatial relations and political-economic processes. Additionally, fragmented knowledge of infrastructure across different disciplines undermines the development of robust planning strategies. Comparative analysis of strategic spatial plans from Auckland, Melbourne and Vancouver examines how infrastructures are instrumentalised to support planning goals. Across the three cases, the analysis identified four common infrastructural modalities: rescaling socio-spatial relations through targeted intensification, intra-urban mobility upgrades and containment boundaries; re-localising socio-spatial relations to the suburban scale with 'complete communities'; protection of 'gateway' precincts; and local planning provisions to support housing affordability. By examining infrastructure through a theoretical framework for suburban infrastructures, this analysis revealed how infrastructures exert agency as artefacts shaping socio-spatial relations and through the internalisation of political-economic processes. Each modality mobilised infrastructure to support goals of global competitiveness, economic growth and 'liveability'.

FINDINGS suggest that spatial strategies should take a user-focused approach to infrastructure to meet the needs of diverse urban populations, and engage directly with the modes of infrastructure project delivery to embed planning goals across design, delivery and operations stages. Stronger institutional mandates to control land-use and provide affordable housing would improve outcomes in these city-regions.
