Project specifications
The naturalisation of Tarralla Creek represents a strategic shift from purely flood conveyance to a community-led project delivering many benefits for current and future generations. The creek’s transformation into a meandering, sustainable watercourse, running through an expansive 12,500 m² wetland system, filters and cleans the water, improves biodiversity through habitat creation, and manages flooding issues for the catchment. Passive recreation opportunities and lookouts surround the wetland, re-engaging the community with the place and water, all linked by a network of walking paths that enhance universal access routes.

Project details
Innovation
The Tarralla Creek project stands out for its innovative approach in transforming a neglected urban waterway into a thriving ecosystem and community asset. Key innovations include the daylighting of the underground creek to its natural watercourse, creating a 12,500 m² wetland for stormwater management and biodiversity enhancement, and integrating Blue Green Infrastructure principles to improve water quality and reduce flood risks. The project's design incorporates biophilic elements such as extensive planting, walking paths, and cultural-inspired structures like Coreten steel picnic shelters and a bird hide, fostering a deep connection between residents and the natural environment. Community engagement was integral, with local input shaping the project's development and ongoing stewardship, setting a benchmark for sustainable urban renewal and ecosystem restoration in Melbourne.
Maintenance
The maintenance of the Tarralla Creek project will be ensured through a comprehensive management plan that includes regular monitoring and upkeep of the naturalized watercourse, wetland, and planted areas. Maroondah City Council, in collaboration with project stakeholders, will oversee routine tasks such as vegetation management, litter removal, and infrastructure upkeep to maintain water quality and ecosystem health. Community engagement will play a crucial role in stewardship activities, including educational programs and volunteer opportunities. Sustainable practices, such as water-efficient irrigation and native plant selection, will be integrated into ongoing maintenance to promote ecological resilience and long-term sustainability of the site as a valuable urban green space.
Project ecology
The Tarralla Creek project implemented several strategies to reduce, reuse, and recycle waste throughout its development. Construction materials were sourced locally wherever possible to minimize transportation emissions, and recycled materials were prioritized for use in infrastructure. Waste generated during construction was segregated on-site to facilitate recycling of materials such as concrete, timber, and metals. The project also minimized waste by carefully planning material quantities and reusing excavated soil and vegetation where suitable. Additionally, sustainable practices were incorporated into the design and maintenance of the site, including water-efficient landscaping and energy-efficient lighting. These efforts contributed to reducing the project's environmental footprint and promoting responsible resource management in line with sustainable development principles.
Biophilic design
The Tarralla Creek project incorporates several elements of biophilic design, including the restoration of the natural watercourse and the creation of a 12,500 m² wetland, which reconnect people with nature through direct contact with water and diverse plant life. The extensive planting of over 87,000 aquatic and terrestrial plants enhances biodiversity and creates natural habitats that attract wildlife. The inclusion of walking paths, lookouts, and passive recreation areas encourages outdoor activities and community engagement with nature. Design elements such as Coreten steel picnic shelters and a bird hide inspired by traditional eel traps integrate natural materials and cultural references, fostering a deeper connection to the local environment and heritage.
Users
The users of the Tarralla Creek project include local residents who benefit from enhanced recreational spaces, improved aesthetics, and increased biodiversity. Community groups, such as schools and scout groups, utilize the area for educational and citizen science projects. Visitors from nearby regions come for leisure activities and cultural engagement, drawn by features like picnic shelters and bird hides inspired by indigenous designs. Additionally, environmental enthusiasts and wildlife observers enjoy the restored natural habitats, while the broader community benefits from the project's contributions to flood management, water quality improvement, and climate resilience.

Please describe aspects of the project contributing to sustainable urban development?
The Tarralla Creek project contributes to sustainable urban development by transforming a neglected waterway into a vibrant, naturalized ecosystem that integrates water management, habitat creation, and community engagement. The project’s wetland system treats stormwater and enhances water quality, while extensive planting improves biodiversity and green space. By incorporating Blue Green Infrastructure principles, the project ensures long-term ecological resilience and reduces urban heat island effects. Additionally, the design promotes passive recreation, cultural engagement, and educational opportunities, fostering a deeper connection between the community and the environment. This holistic approach supports environmental sustainability, social well-being, and economic vitality, creating a more livable and resilient urban area.
How the project contributes to climate adaptation?
The Tarralla Creek project contributes to climate adaptation by incorporating Blue Green Infrastructure principles, which enhance resilience to climate impacts such as flooding and heatwaves. The creation of a wetland and the restoration of the natural watercourse improve stormwater management, reducing flood risks and enhancing water quality. Extensive planting of over 87,000 aquatic and terrestrial plants increases urban green space, mitigating the urban heat island effect and providing cooler, shaded areas. These actions create a more resilient ecosystem that can better adapt to climate changes, supporting both environmental sustainability and community well-being.
How is the project supporting local biodiversity and urban ecosystems?
The Tarralla Creek project supports local biodiversity and urban ecosystems by daylighting the creek, creating a 12,500 m² wetland to treat stormwater, and planting over 87,000 aquatic and terrestrial plants, which enhance habitats and water quality. Natural watercourse features like riffles and meanders oxygenate the water and create microhabitats, boosting species diversity. The project also includes educational opportunities and culturally inspired elements to foster community engagement and stewardship. By integrating Blue Green Infrastructure principles, the project ensures long-term sustainability and resilience, transforming the creek into a thriving, biodiverse urban ecosystem that benefits both wildlife and residents.
