28 September 2020 Darren Cheeseman MP Chair Legislative Assembly Environment and Planning Committee Inquiry into Environmental Infrastructure for Growing Populations Parliament House Spring Street EAST MELBOURNE VIC 3002 Dear Mr Cheeseman, SUBMISSION TO THE INQUIRY INTO ENVIRONMENTAL INFRASTRUCTURE FOR GROWING POPULATIONS I welcome the opportunity to provide Infrastructure Victoria’s views to the Legislative Assembly Environment and Planning Committee Inquiry into Environmental Infrastructure for Growing Populations. The inquiry is a valuable opportunity for Parliament to consider Victoria’s requirements and demand for environmental infrastructure, and I am pleased Victorians are being provided the opportunity to have their say on this important infrastructure type. As an infrastructure body, Infrastructure Victoria is focused on infrastructure responses that address the economic, social and environmental needs of Victorians. In Victoria’s 30-year Infrastructure Strategy, published in 2016, we identified the importance of increasing the amount and quality of green infrastructure in urban settings to support a range of outcomes, including creating open space for planned and incidental exercise, improving biodiversity by increasing forested and planted areas, helping reduce urban temperatures, and supporting water-sensitive design to mitigate flooding events. From our consultation with local communities in densifying suburbs, safe, adaptable multi-functional spaces and green space are essential in managing the impacts of greater residential densities and providing for growing populations. We have seen that people have heavily used green public open spaces during the COVID-19 pandemic, further demonstrating its health and resilience value. Infrastructure Victoria is currently further reviewing the importance of environmental and green infrastructure as we update Victoria’s 30-year Infrastructure Strategy. A draft of the updated Strategy will be released for public consultation later this year, ahead of delivery of the final updated strategy to Parliament in 2021. If you or the Committee would like to discuss Infrastructure Victoria’s submission, references or approach to updating Victoria’s 30-year Infrastructure Strategy, please contact me or Mr Charles Waingold, Director of Networks and Planning, Sincerely, Michel Masson Chief Executive Officer Infrastructure Victoria Level 33, 140 William St, Melbourne 3000 | T (03) 9936 1737 infrastructurevictoria.com.au OFFICIAL SEPTEMBER 2020 SEPTEMBER Inquiry into Environmental Infrastructure for Growing Populations Infrastructure Victoria submission to the Environment and Planning Committee Official 1 About us Infrastructure Victoria is an independent advisory body, which began operating on 1 October 2015 under the Infrastructure Victoria Act 2015. Infrastructure Victoria has three main functions: • preparing a 30-year infrastructure strategy for Victoria, which is refreshed every three to five years • providing written advice to government on specific infrastructure matters • publishing original research on infrastructure-related issues Infrastructure Victoria also supports the development of sectoral infrastructure plans by government departments and agencies. The aim of Infrastructure Victoria is to take a long-term, evidence- based view of infrastructure planning and raise the level of community debate about infrastructure provision. Infrastructure Victoria does not directly oversee or fund infrastructure projects.

Introduction Infrastructure Victoria welcomes this opportunity to provide a submission to the Legislative Assembly Planning and Environment Committee Inquiry on Environmental Infrastructure for Growing Populations. As an independent infrastructure advisory body, Infrastructure Victoria is focused on infrastructure responses that address the economic, social and environmental needs of Victorians. Environmental infrastructure is an increasingly important infrastructure type to address all of these needs. Infrastructure Victoria’s work commonly refers to environmental infrastructure as ‘green infrastructure’, which is broadly defined to include parks, green open space, green spaces, green links and corridors, nature reserves, woodlands and bush, open countryside, private gardens, sporting fields, and all vegetation. We have defined the various terminology used in this report in Figure 1. In Victoria’s 30-year Infrastructure Strategy, published in 2016, we identified the importance of increasing the amount and quality of green infrastructure in urban settings to support a range of outcomes, including creating open space for planned and incidental exercise, encouraging everyday trips by walking and cycling, improving biodiversity by increasing forested and planted areas, helping reduce urban temperatures and supporting water-sensitive design to mitigate flooding events.1 From our consultation with local communities in densifying suburbs, safe, adaptable multi-functional spaces and green space are essential in managing the impacts of greater residential densities.2 We have seen that people have heavily used green public open spaces during the COVID-19 pandemic, further demonstrating its health and resilience value. Vegetation cover is falling in Melbourne and particularly on private property. This is due to a variety of factors including larger houses covering more land, more intense uses of land such as townhouses and apartments, and general removal of vegetation. Vegetation is important in urban areas as it can contribute to ameliorating urban heat islands. Work done by Infrastructure Victoria maps heat vulnerability which highlights where additional vegetation planting should be prioritised (see 3.2.3 below). These observations and trends are similarly applicable to areas across Victoria experiencing trends in growth and development, particularly urban areas of Victoria’s larger towns and regional centres. To improve the benefits to Victorians, we recommend key actions including creating an interconnected network of open spaces, improving the quality of and access to existing space, and a better use of existing publicly owned land for the public to benefit from environmental infrastructure. We also explore the need to address challenges with open space contribution schemes, how to better offset the removal of vegetation by development, and how to better fund open spaces. Infrastructure Victoria is currently further reviewing the importance of environmental and green infrastructure as we update Victoria’s 30-year Infrastructure Strategy, which will consider metropolitan Melbourne as well as Victoria’s regions more broadly. A draft of the updated Strategy will be released for public consultation later this year, ahead of delivery of the final updated strategy to Parliament in 2021. OFFICIAL4 Inquiry into Environmental Infrastructure for Growing Populations Figure 1: Definitions Term Definition Green infrastructure A natural life support system. Its elements work together to improve the environmental health of an area and mitigate the effects of climate change.3 This includes parks, green open space, green spaces, green links and corridors, nature reserves, woodlands and bush, open countryside, private gardens, sporting fields, and all vegetation. This can also include green walls, Water Sensitive Urban Design, green tram tracks, roof gardens and community gardens. Green links and corridors A strip of land that provides for general movement and/or habitat to support wildlife within an urban environment, which could allow the movement of wildlife along it. Common green corridors include railway embankments, riverbanks and roadside grass verges, along with linear parks.4 Also see ‘interconnected open space network’. Green open space Areas that are publicly accessible, have some vegetation, and generally support some recreational activity (including parks, sports fields and nature reserves)5 Interconnected open space network Areas of green space that are connected through green links. Green links can be green open spaces (such as parks), linear green spaces (bike and walking paths), or tree canopy coverage on streets. An interconnected network promotes the movement of species (biodiversity benefits), encourages active transport,
