HYPE Sustainability was engaged by the ABOUT EAST OF ABERLINE Warrnambool City Council (WCC) to undertake analysis into low carbon and climate resilient Located approximately 4 kilometres north east from Warrnambool, the responses that can inform the East of Aberline East of Aberline (EoA) site covers an area of 360 hectares and has the Precinct Structure Plan. potential to deliver 4,000 dwellings for the region. This report has been developed through research, The site is bounded by pastoral and grazing land to the north and east beyond Wangoom and Horne road, and residential development to the analysis and targeted engagement. The objective of south east of the site along Aberline and Boiling Down road. this report is to highlight and analyse opportunities that are relevant to the location and scale and identify While EoA is largely cleared, the presence of ecological assets such as Tozer Reserve, and Russell Creek dissect the site and provide an implementation pathway for these in the Precinct opportunities to integrated biodiversity conservation with residential Structure Plan. development to create a climate resilient community. Undertaking this review now as part of Precinct PURPOSE OF THIS DOCUMENT Structure Plan development will ensure that sustainability is a core driver for the future planning of This report represents the first stage of the project. It highlights relevant the precinct. technical and policy context and stakeholder perspectives. The purpose is to highlight opportunities for low carbon and climate resilience and a number of mechanisms which can be used to drive those opportunities. This project has adopted the category headings in the Sustainable Subdivisions Framework for the analysis - consistent IMAGE: TOZER RESERVE AND RUSSELL CREEK ARE PROPOSED TO with work recently led by HIP V.

SPACE (SOURCE: SPIIRE) The Sustainable Subdivisions Framework (SSF) sets out a series of sustainable built environment opportunities which can be influenced The seven Framework categories include: through the development planning and subdivision planning processes. _ Site Layout and Liveability Sustainable subdivisions can be facilitated through a number of planning stages including Precinct Structure Plans, Development _ Streets and Public Realm Plans, and through provisions already contained within the Planning _ Energy Scheme. The Framework responds specifically to the subdivision stage, _ Ecology but recognises precinct structure planning as a foundation of good _ Integrated Water Management (IWM) subdivisions and the building level opportunities if mechanisms such as Design Guidelines are adopted to control them. _ Urban Heat _ Circular Economy (Materials and Waste) These opportunity areas are core to developing a climate responsive precinct and pursued because of their importance to planning at this scale and in this location. © COPYRIGHT HIP V.

Government’s commitment under the Climate Change These could be emissions from fuel use, refrigerants and electricity Act 2017 to reduce greenhouse gas emissions for generation taking place on-site in the precinct Victoria to zero net emissions by 2050, which requires _ Scope 2 emissions include offsite emissions from purchased immediate action to reduce carbon emissions in the electricity, heat, cooling and steam (i.e. energy produced outside the geographic boundary of the precinct but consumed within the built environment. precinct) There is strong support in State policy for embedding _ Scope 3 emissions include all indirect emissions that occur as a result of the activities of the precinct, but occur from sources outside the sustainability into new Precincts.

The majority of these are Scope 1 and 2 emissions, however the waste category includes some Scope 3 emissions.
