Climate Change

The City of South Perth is committed to addressing climate change. As custodians of the local environment and infrastructure, the City is actively working to understand the potential impacts of climate change, as well as taking action to prevent those impacts wherever possible. 

Climate change will affect many areas of City services including building, planning, environmental management, infrastructure, public health and community services. 

A strategic approach to climate change

The City is guided by its Strategic Community Plan 2020-2030, which includes two strategies (listed below) under the outcome Resource Management and Climate Change. 

  • Promote and implement sustainable water, land and energy management practices
  • Manage the risks associated with climate change and finite resource availability.

A review of the City’s Climate Change Strategy 2010-2015 was recently undertaken to ensure that actions remain current and based on latest scientific knowledge. The City has also undertaken a Greenhouse gas emissions forecast to establish emissions reduction targets.

Climate change risk assessment

In 2010, the City undertook a series of organisation-wide workshops to develop a risk assessment for climate change impacts. This trial project was a first in Western Australia. The purpose of the project was to undertake a review and assessment of the City’s risks in terms of the effects of actual or potential climate change impacts. The risk assessment formed the basis of the City’s approach to climate change, including its climate change strategy. 

Climate change flood risk and vulnerability 2017

The City, in partnership with Eastern Metropolitan Regional Council, the Department of Water and five other local governments, is undertaking a Flood Risk and Vulnerability Assessment of the City’s northern foreshore with the aim of producing a Floodplain Development Strategy. 

This project will provide the City with updated modelling and mapping of the northern foreshore, with consideration of the effects of climate change. This will inform and develop mitigation strategies and decision-making on proposed land use and development of flood prone land.

Foreshore vulnerability mapping 

This part of the project involves: 

  • Preparation of a digital elevation model
  • Hydraulic modelling and the assessment of Swan and Canning River tidal and storm surge water levels 
  • Revised floodplain mapping for a range of flood events.

The aim of this stage is to provide updated hydraulic modelling and mapping with consideration of the effects of climate change. This will inform decision-making and mitigation strategies regarding the use of flood prone land.

Property and infrastructure vulnerability mapping 

This stage of the project will highlight key regions that may benefit from increased protection. The overall objective is to provide risk assessment and mitigation strategies to inform decision making regarding public and private property and infrastructure. This will facilitate the development of adaptation emergency response planning activities.

Interactive flood mapping information

This part of the project will commence in July 2017, using information from previous stages of the project. This will involve developing a web-based interactive flood intelligence site to enable local government, state government and emergency management agencies to have a greater understanding of identified flood risks. This stage will also include Flood Risk Adaptation Planning for participating local governments and their stakeholders to understand, quantify and begin developing flexible adaptation options.

Climate change adaptation

The City will use the information from the climate change risk and vulnerability assessment process to develop a climate change adaptation plan.

Climate change reporting

The City is currently reviewing its sustainability reporting framework, which will inform the tools used to measure energy, emissions and water data.
