How can the West End neighbourhood in Brisbane city plan for climate change from the ground up?
Several hundred designers and planners workshopped ideas with residents in 2019. These ideas have been further brainstormed by Kurilpa Futures community group in 2020. The resulting ideas form a compelling and practical list of actions for both community and government to act.
The report was edited by environmental planner Mark Allen and John Mongard in August, 2019.
2 Degrees: Design for Climate Adaptation
This climate adaptation co-design workshop has been prepared by John Mongard Landscape Architects and is intended to be able to be used by any group within their own neighbourhood. Grass roots action is likely to be the forerunner for governmental action. In many parts of Australia communities can prepare themselves for the shifting climate, in the coming years.
Purpose of a neighbourhood climate strategy
In the increasingly complex and confusing world of climate change, we need shared, simple and sensible thinking about what helps us to respond effectively as a community. As we face decisions and advocate changes that affect our community, we can choose to embrace our diverse world views, engage our concerns about climate risks, and act to thrive as a community in our neighbourhood.
A climate framework
Our climate strategy focuses on resilient adaptation: an approach to climate adaptation that understands and respects the world views and the shared needs of our community and which intentionally designs and develops the urban setting to respond to our shared applications. For us this involves three community actions:
- Resetting: Expectations
- Regaining: Knowledge, Skills & Assets
- Rebounding: From Setbacks
For more detail about getting up a neighbourhood climate framework, refer to: The Kurilpa Climate Strategy (by John Mongard, Bob Spiers and Pam Burke, located at www.mongard.com.au).
Workshop background
By the year 2030 it is projected that our climate will have altered by 2 degrees in temperature above pre-industrial times. Our cities and places will need to be adapted for this climate shift: within ten years.
Communities, planners and designers will need to strongly alter their patterns and practices to achieve this adaptation. This workshop aims to make people think about actions required to ramp up and prepare for this climate shift.
Workshop outcomes
This report summarises the ideas and actions suggested during the summit workshop ,which was attended by over 150 people.
Designers, educators,community members and other attendees were faciliated by 8 landscape architects and planners, working in groups of 7-10 people ,and brainstorming around seven local areas within the Kurilpa Penninsula.
Workshop scenario: planning for the summer of 2030 (+2d)
The climatic shift is most likely to be of impact in our summers. In Brisbane, we will see a shift to a more hotter style climate: longer summers with more extreme heat days, less rainfall and more frequent and strong storm events. Hot dry wind will reduce humidity and increase fire risks. Impacts from flooding and overland water will likely increase in many low and water prone neighbourhoods.
Urban heat stress will increase particularly in open and hard city areas. We will find it harder to move around or cool down in our neighbourhoods. Urban heat stress will increase particularly in open and hard city areas. We will find it harder to move around or cool down in our neighbourhoods, homes and streets.

Summary ideas for adapting to water/storms/drought
Water Sensitive Urban Design (WSUD)
Apply and utilize Water Sensitive urban Design (WSUD) principles and techniques to existing and new development. These include:
- Swales *****
- Permeable paving *****
- Channeling and harvesting overland flow within and between sites to reduce impacts of flooding, sustain vegetation and create habitat. Techniques include rain gardens, targeted tree species, ponds, billabongs and street gardens. *****
- Street tree programs that target flood and drought resistance. ****
- Urban forests
- Riverside parks that can be flooded during significant rain/storm events.
Harvesting & Capture
Utilize significant rain/storm events to capture and harvest water for purposeful reuse. This is to be achieved by:
- Designing underground water storage tanks in parks, gardens and under roads. *****
- Creating water-retaining spaces in parks such as reed beds and temporary wetlands. ****
- Neighborhood-scale overland flow collection and water quality treatment.
Biodiversity
Urban biodiversity can be protected and enhanced by:
- Creating water habitats in urban areas. ****
- Protecting mangrove ecosystems and undertaking flood tolerant planting along the river. **
Building Codes
Introduce and/or amend building codes to improve built environment resilience to impacts of extreme weather. Improvements to building codes could include:
- Allowing for underground power systems to improve cyclone resilience.
- Requiring roof /wall framing systems and building codes to design for more frequent and intense storm, flood and drought conditions.
- Reducing building footprints on sites to enable greater scope for flood and water management.
