This note DES 8, originally published in November 1995, was reviewed by Steve King in November 2000. This summary page includes recent updates to the topic since publication. This Note outlines the energy efficiency and sustainability issues to be considered in residential site planning; and discusses ways of planning subdivisions to preserve existing vegetation, to minimise site disturbance and exposure to bushfire hazards, and to reduce pollution of waterways due to stormwater and urban run-off. It is supported by a companion Note on Residential Site Development.
