Flooding and stormwater management

Flooding and stormwater management

We are undertaking various flood and stormwater management initiatives, aimed at building a more resilient and liveable Manningham and to facilitate robust planning for the future.

This page provides information relating to the Integrated Water Management Strategy and Manningham Flood Mapping Project.

Help shape Manningham’s water future

Our draft Integrated Water Management (IWM) Strategy guides how we can contribute to maintaining our liveability, improve waterway health and support community wellbeing.

The draft strategy will guide the management of all sources of water over the next 10 years. It will also address emerging challenges such as population growth, climate change and increasing flood and drought risk.

There are a number of opportunities for you to learn more about the draft IWM Strategy and chat with the team. These include:

• Warrandyte Riverside Market on Saturday 1 November
• Park Orchards Market on Saturday 15 November
• Tunstall Square Market on Sunday 30 November

A drop-in session at MC2, Doncaster. between 6:00pm and 8:00pm on Wednesday 3rd December, registrations are required.

Manningham Flood Mapping Project

Under Regulation 148 of the Building Regulations 2018, Council is now required to prepare mapping for areas under its control that are liable to flooding.

Planned for completion in 2025, the Manningham Flood Mapping Project is being delivered by Melbourne Water and Manningham Council.

It will provide maps indicating flood extents for the regional and local drainage networks in Manningham, for a range of probable storm events.

Flood mapping involves computer modelling, which simulates how stormwater runoff travels through catchments.

Current and reliable flood mapping information is essential to understand and manage flood risk. It is used to:

• assess the frequency, severity and location of flood risks within catchments
• better plan and prioritise mitigation activities
• plan for future development
• build community awareness; and
• inform emergency management planning.

The flood mapping process will also be informed by the latest available data and guidance recommended under the 2019 version of Australian Rainfall and Runoff.

A new Stormwater Management Strategy for Manningham

We’re developing a Stormwater Management Strategy to help identify, manage and reduce flood risk to people, property, infrastructure and the environment.

The Strategy will guide our planning and investment in the long-term Capital Works Program to support a healthy, safe and resilient community.
