Most major cities in Australia expect significant infill development over the coming decades. Without significant intervention, 'business as usual' is expected to have considerable influence on the hydrology, resources efficiency, liveability and amenity of our cities. This project aims to develop and apply a performance framework to understand infill impacts, create design options and processes through case studies, and identify improved governance options and arrangements.

The project builds on previous CRCWSC research that developed an urban metabolism framework  (Project B1.2 Catchment scale landscape planning for water sensitive city-regions in an age of climate change), documented best practice water sensitive urban design (Project D5.1 Urban intensification and green infrastructure: towards a water sensitive city), and identified the cooling effects of water sensitive practices in urban renewal works (Project B3.2 The design of the public realm to enhance urban microclimates). The project will also utilise a range of existing CRCWSC tools and products such as the WSC Toolkit (Project D1.5 Water Sensitive Cities Modelling Toolkit) and the WSC Index (Project D6.2 Developing a Water Sensitive Cities Index).

The project principally focuses on developments from individual lots through to the precinct scale. To achieve its objectives, the project will work closely with the TAP (Tools and Products) program, IRP3 (Evidence-based integrated urban planning across different scales) and IRP2 (Comprehensive economic evaluation framework). The work will be underpinned by strong stakeholder engagement, overseen and chaired by an end-user steering committee. Ultimately, the work is expected to contribute to improved infill governance.


This project will deliver the following outputs:

  • An infill development evaluation framework to understand and manage infill impacts. The framework focuses primarily on quantifying hydrological performance of infill and related design. It allows identification of opportunities specific to different developments.
  • A catalogue of water sensitive design options for different scale typologies.
  • Identification of improved governance arrangements in conjunction with real world projects with modelling analysis to support selection of optimal outcomes.
  • Case studies that have applied the infill development evaluation framework.
