Tasmanian Climate Change Adaptation Pathways Project


Through the Tasmanian Climate Change Coastal Adaptation Pathways (TCAP) project, the City of Clarence developed a long term adaptation strategy in consultation with the community to prepare for the effects of climate change and urbanisation in four sites including the Lauderdale foreshore area. 

The TCAP project provides a phased adaptation strategy for Lauderdale to ease the effects of erosion and inundation based on the expectation that the suburb will be affected by 0.9 m sea level rise. If coastal hazards are not addressed, most of the properties in Lauderdale would be at significant risk from erosion, inundation or both. A number of natural areas fringing the suburb contain threatened species or communities and important migratory bird habitat and fish breeding grounds could also be adversely impacted.

The most challenging outcome was that although there was significant prior investigations of potential adaptation works, when the Lauderdale community’s preferred approach (beach nourishment alone for the short term) was assessed in more detail, costs were higher and practicality lower than had been expected, requiring a more intrusive and expensive approach adopted to be effective.

Risks and Impacts Addressed 
  • Coastal erosion, sea level rise/coastal inundation

  • Rising and increasingly saline watertable

  • Concern about significant growing present day erosion risk and more frequent sea water across the highway since 2000 drove both Council action and strong community engagement.

Drivers for Adaptation Action 

Ongoing history of response to impacts.

Big shift forward during 2006 - 2008 with DIICCSRTE funded Clarence City Council (CCC) and TCAP work.

Outcomes Achieved 

Detailed plans and staging for responding to short and longer term risk from present day accommodating a sea level rise of about 0.9 m.
