Submitted in Originality Declaration section

The "Aitken Creek Oasis" project is a conceptual design for a case study at Aitken Creek, where we acted as developers to design an innovative urban development that diverges significantly from traditional approaches. Our nature-positive suburban design includes three main characteristics. Firstly, it increases housing density by incorporating medium-density Victorian Government standard townhouses with three floors. Secondly, it establishes a large nature reserve dedicated to grassland frogs an

Research details

Breef research description

The "Aitken Creek Oasis" project focuses on developing an innovative urban design concept for Aitken Creek in Melbourne's northern suburbs. This project aims to address urban growth challenges while enhancing biodiversity and promoting sustainable water management. Key features include medium-density housing integrated with a nature reserve for endangered species and a secondary creek with phytodepuration wetlands. Modeled under Water Sensitive Urban Design (WSUD) principles, this concept demonstrates the feasibility of achieving climate-resilient suburban development that improves environmental quality and community well-being.

Research outcomes

Is the research a precursor to expected follow up research?

Yes, the research serves as a precursor to expected follow-up research. Its innovative approach in integrating Green Infrastructure (GI) and sustainable urban development practices sets a foundation for further studies. Future research could explore scaling up these strategies in larger urban contexts, refining methods for biodiversity conservation and water management, and assessing long-term socio-economic impacts. This continuity aims to advance knowledge and application of GI in urban planning, addressing ongoing challenges and opportunities for enhancing environmental sustainability and community well-being.

How does the research address the issue of water stewardship?

The research addresses water stewardship through innovative Green Infrastructure (GI) strategies. It includes phytodepuration wetlands and natural water treatment systems to manage stormwater and treat greywater, enhancing water quality and conserving resources. By promoting recycled greywater for irrigation and integrating sustainable water management practices like rainwater harvesting, the research ensures efficient water use and minimises impact on natural water systems. Overall, these efforts demonstrate a commitment to improving ecosystem health and advancing water stewardship in urban environments.

How does the research address the human well-being aspects of GI?

The research promotes the health and well-being of residents by fostering a socially connected community that is diverse and integrated. All buildings are designed for accessibility, with 10% of housing reserved for high accessibility requirements. These measures ensure that the community is inclusive and supportive of diverse needs, enhancing overall quality of life and social cohesion among residents.

How does the research address the economic aspects of GI?

The research addresses the economic aspects of Green Infrastructure (GI) through several strategic approaches. Firstly, by integrating sustainable water management practices such as greywater irrigation and natural water treatment systems, the project reduces operational costs associated with water supply and treatment. This includes savings on water bills for residents and municipalities alike. Secondly, the project significantly reduces costs related to pollution removal, particularly nitrogen, benefiting waterways and the bay managed by Melbourne Water. This proactive approach not only minimizes environmental impact but also avoids potential fines and expenditures associated with water quality management. Thirdly, promoting medium-density housing and energy-efficient building standards reduces long-term maintenance and utility costs while enhancing overall affordability and livability for residents. Additionally, creating social amenities and recreational spaces within the GI framew

How does the research address the environmental sustainability aspects of GI?

The research addresses environmental sustainability aspects of Green Infrastructure (GI) through several key strategies. Firstly, it implements phytodepuration wetlands and natural water treatment systems along a secondary creek to manage stormwater runoff effectively, reduce pollution, and improve water quality. These systems also serve a dual purpose by treating greywater from residential areas, enhancing water conservation and reducing demand on potable water supplies. Secondly, the project integrates green spaces and native vegetation, which contribute to urban cooling, air quality improvement, and carbon sequestration, thereby mitigating the urban heat island effect and supporting climate resilience. Thirdly, by promoting medium-density housing and energy-efficient building standards, the research reduces overall environmental footprint and resource consumption, fostering sustainable urban development practices. Overall, the research demonstrates how GI can play a crucial role in

How does the research address social aspects of GI?

The research addresses social aspects of Green Infrastructure (GI) in several ways. Firstly, it integrates social amenities such as lagoons, trails, sport areas, playspaces, and cooling areas, which enhance community well-being by providing recreational spaces for residents. These amenities not only promote physical activity and leisure but also foster social interaction and community cohesion. Secondly, the design includes accessible green spaces and community gardens within the buildings, promoting a sense of ownership and stewardship among residents. Thirdly, by incorporating phytodepuration wetlands and enhancing natural landscapes, the project improves aesthetic quality and environmental awareness, contributing to a healthier and more livable urban environment. Overall, the research demonstrates how GI can positively impact social dynamics by creating inclusive and engaging spaces that enhance quality of life within urban settings.

How does the research address the topic of biodiversity?

The research addresses biodiversity through several strategic approaches. Firstly, it designates a significant portion of the project site as a nature reserve specifically tailored to accommodate endangered local species such as grassland frogs and other native wildlife. This reserve aims to restore and enhance natural habitats, including native grasslands, ensuring the preservation of biodiversity within the urban environment. Secondly, the project integrates green infrastructure elements like phytodepuration wetlands along a secondary creek, which not only serves as a natural water treatment system but also creates additional habitats for local flora and fauna. By implementing these measures, the research actively promotes biodiversity conservation while demonstrating sustainable urban development practices.

What types of GI multifuncionality are addressed by the nominated research?

The nominated research addresses several key functions of Green Infrastructure (GI) in urban development. It focuses on biodiversity enhancement through the creation of habitats for endangered species within a dedicated nature reserve and secondary creek with phytodepuration wetlands. Additionally, the project integrates stormwater management strategies, utilizing these wetlands to treat residential water runoff effectively, reducing pollution and managing stormwater flow. Social amenities are enhanced through the inclusion of lagoons, trails, and water play areas, promoting community well-being and providing recreational spaces. Furthermore, the design of medium-density housing supports climate resilience efforts by mitigating urban heat island effects and improving energy efficiency, thereby fostering sustainable urban growth and environmental stewardship.
