The Dandenong IWM Forum is governed by an open and transparent IWM planning process. This process assumes a holistic, whole-of-cycle approach to determine water cycle solutions, considering regulatory accountabilities and delivery responsibilities. Each organisation has an important role to play in the decision-making and management of the catchment’s water, resources and assets. Port Phillip Bay.

Guiding principles for collaboration The purpose of the Dandenong IWM Forum is to provide a collaborative platform for overseeing, supporting IWM Forum and, where necessary, facilitating water’s contribution to resilience and liveability in Victoria. Applying an IWM approach, the Forum will: • Consider the collective community needs in the regional context IWM Working Group and develop an overall strategic direction accordingly. • Complement and feed into existing water and land planning processes, collaborative networks, forums and associations. • Commit best endeavours to facilitate IWM Project IWM Project IWM Project multi-stakeholder initiatives, share Group Group Group organisational expertise and advance sectoral learnings.

Regional context The Dandenong IWM Forum Area encompasses some of Victoria’s most iconic waterways and landscapes. The catchment covers an area of approximately 1,236 km2, extending in the northeast from the foothills of the Dandenong Ranges south to Mornington Peninsula on Port Phillip Bay. It includes regional catchments flowing into Port Phillip Bay from Port Melbourne to Point Nepean. The landscape of the Dandenong catchment varies from mountainous forested areas, wetlands and coastal beaches, to densely populated and expanding areas on Melbourne’s fringe. While the Forum Area includes several Population particularly those surrounding verdant national parks abundant in Dandenong, Cranbourne and native vegetation and wildlife, less The Dandenong IWM Forum Area Frankston.

The region sustains a range of for many suburbs across the region, recreational activities, including tourism, fishing, boating, cycling, walking and beach escapes. Commercial activities in the catchment include viticulture, horticulture and livestock production, as well as notable manufacturing, technology and education sectors. The Dandenong catchment includes areas of significant value where Aboriginal people have lived for thousands of years. Archaeological evidence from the Dandenong Ranges shows Aboriginal people lived in this region over 35,000 years ago. St Andrews Beach.

Chapter 2 Vision and strategic outcomes By valuing water in its entirety, the Dandenong catchment is a well-planned, healthy, resilient and thriving environment for people and nature – now and into the future. Collaboration to develop The seven primary strategic outcome These outcomes acknowledge the shared vision and areas to achieve this vision, as well the breadth of water plans, strategic outcome areas as the secondary outcome areas environmental strategies and nested beneath each primary area, land use plans developed by The IWM Forum demonstrates a were developed collaboratively each partner organisation. robust and transparent process by the IWM Forum partners. of collaboration amongst local governments and a range of stakeholders with an interest in water. Central within this process are the community values, local interests and place-based opportunities represented by each Forum member organisation. The IWM Forum recognises the valuable contribution of these many and diverse actors in supporting a transformative approach to the planning and management of our wider water cycle. Each of these organisations played a leading role in determining a shared vision for IWM unique to each of the five metropolitan Melbourne catchments. Waterways Estate, Edithvale.
