Climate Change Vulnerability Report

Vulnerability of the Cottesloe Foreshore to the Potential Impacts of Climate Change

Cottesloe is potentially at risk from coastal erosion due to the proximity of development to the present shoreline. In light of this, the Town of Cottesloe commissioned the current study in order to ensure it is well informed and prepared to deal with any future challenges in the management and maintenance of its valuable coastal resources and infrastructure.

The main aim of the Cottesloe Climate Change Vulnerability Assessment Project was to establish potential risk to existing key coastal infrastructure under a range of future climate scenarios. The overriding objectives to achieve this aim were:

·         Analysis of contemporary coastal conditions (environmental conditions and resultant coastal change)

·         Determination of scenarios for future climate change

·         Prediction of impacts on the physical coastal environment

·         Implications of physical change for existing infrastructure.

In addition, the possible strategic alternatives for adaptation were also considered.
