The spread of residential land use across the region, a large proportion of which is held under private
ownership means that development of climate change adaptation options that impact upon private
residential development will need to involve engagement with a very large group of people across with
wide demographic characteristics. A suitable engagement strategy will need to be developed to ensure
effective two way flow of information and community buy-in.
Figure 9.6
summarises residential land uses which are located outside of Residential Zones. In West
Torrens, these are predominantly located in Commercial and Industrial Zones, while in Port Adelaide
Enfield, they predominate in the Port Adelaide Regional Centre Zone and in the Coastal Marina Zone.
Residents living in residential properties in non-residential zones may be subjected to the impacts of other
uses, such as heavy vehicle movements, noise and visual appearance. In addition, residential
development located outside of residential zones is less likely to be replaced with residential development
upon the redevelopment of the land in comparison with residential development in residential zones.
9.2.1.1. Climate Change Impacts and Implications for Residential Land Use
Climate change impacts on residential land will vary from location to location, and may include:
x
Flooding and inundation from sea level rise, storm surge, and episodic rises in surface waters.
x
Higher temperatures on structures (houses, roads) and private open spaces.
x
Hydrological changes that may cause drying of land, ground movement, and changes in structural
integrity.
These direct impacts may result in how residential land is used and managed in the future. For
example, the use and management of private outdoor space may change as a result of water shortages
(or more expensive water) and warmer summer temperatures. Support services such as waste
management may also need to be reviewed to ensure suitable levels of amenity. Consumer preferences
(e.g. built form including shaded areas, pools, rainwater tanks, power generation) and behaviours (e.g.
mobility, consumption of resources) may also change, which can lead to a change in overall development
patterns. It is also suggested that a significantly warmer climate can impact on the attractiveness of a
city, which affects population growth and labour migration (Estiri, 2012).
Some residential areas may be less able to accommodate new building technologies or features aimed at
improving energy efficiency and occupant ambience due to existing built form or policy settings that
address issues that include interface, heritage protection, siting and appearance of structures.
Stage 2 of the WARCCAP should examine in detail the potential effects that a modified climate will have
on residential land use planning including a review of existing tools that will serve to support climate
change adaptation (e.g. planning policy, building code, administrative practices, engineering codes).
