Why is this a focus area?

Yarra Ranges has some of Victoria’s most important waterways which support a variety of plants and animals, and supply more than half of Melbourne’s drinking water.

Our water systems are under pressure. Short, heavy downpours are happening more often, causing flash flooding and damage. The floods in Lilydale in October 2022 revealed that some neighbourhoods are more at risk, and we need to plan for these types of events.

Simultaneously, hotter, drier weather increases the risk of drought. This makes it even more important to protect our waterways, manage stormwater better and use water wisely so our environment and community stay healthy.

What has the community said so far?

The community wants better drainage and stormwater systems to help prevent flooding, especially in places that are most at risk.

People also want creeks, rivers and wetlands to be protected and restored. This is important not just for nature, but also for safety, recreation, cultural values and long‑term water security.

What has Council been doing in this space?

In 2024–25, Council carried out a range of projects to improve waterway health, reduce flooding and support water security, including:

• Reducing stormwater impacts each year by 61 million litres of stormwater, 373 kg of nitrogen and 24 tonnes of litter and debris with raingardens, swales and wetlands.

• Delivering the Tanks for Platypus Project to slow and gently release stormwater into Monbulk Creek. This helps stop sudden flooding in the creek and protects important places where platypus and other animals live.
