Some of these require buffers to manage odour and noise and some also require licensing to manage impacts from industrial emissions and the disposal of waste products such as treated waste water. Australian Standards are in place to manage impacts from aircraft noise.
Greater Sydney, particularly its rural lands, is at risk from biosecurity hazards such as pests and diseases that could threaten agriculture, the environment and community safety. Biosecurity hazards are managed through the Greater Sydney Peri Urban Biosecurity Program.
Effective land use planning and design can reduce the exposure to natural and urban hazards and build resilience to shocks and stresses. Growth and change need to be considered at a local level when making structural decisions about the region’s growth, and when considering cumulative impacts at district and regional levels. Current guidelines and planning controls minimise hazards and pollution by:
- avoiding the placement of new communities in areas exposed to existing and potential natural hazards
- managing growth in existing neighbourhoods that are exposed and vulnerable to natural hazards
- in exceptional circumstances, reducing the number of people and the amount of property vulnerable to natural hazards, through the managed retreat of development
- using buffers to limit exposure to hazardous and offensive industries, noise and odour
- designing neighbourhoods and buildings that minimise exposure to noise and air pollution in the vicinity of busy rail lines and roads, including freight networks
- cooling the landscape by retaining water and protecting, enhancing and extending the urban tree canopy to mitigate the urban heat island effect (refer to Objective 25, Objective 30, and Objective 38).
The wellbeing and social cohesion of a community can affect a community’s ability to prepare, respond to and recover from acute shocks, noting there are different levels of vulnerability between communities. Planning for strong and cohesive communities is set out in the Liveability Chapter.
