How does flooding impact Bribie Island residents?

Floods can affect us in lots of ways.

Flood water in homes and businesses can cause expensive and heartbreaking damage. Floods can also close roads, so we lose access to work, study, medical care, shops, and family support. Sometimes floods are caused by heavy rain or storms that can damage other infrastructure, like power lines, phone towers and roads. And of course, floods can be deadly for residents, drivers, and the emergency service officers trying to help them.

We will use your stories along with technical data to identify cost-effective options to reduce flooding on Bribie Island.

Moreton Bay City Council (Council) is collecting your personal information for the purpose of informing the Bribie Island Flood Hotspot Mitigation Study project. Your responses will be shared with consultants supporting delivery of this project. Council will also use your contact information to update Council’s customer information records and to contact you about the Project and other functions, services and projects of Council. Council may use the information you provide to inform our other functions, services and projects.

About the project

We are working to find cost-effective ways to reduce flooding in four identified areas on Bribie Island. We are also gathering information to support other flood mitigation and emergency preparedness projects on Bribie Island.

This study aims to identify cost-effective options to reduce flood risks to residents and businesses in the identified areas. We aim to complete this project by the middle of 2025, subject to unavoidable delays.

This study has two parts:

1. Gathering flood stories from the community to inform future potential flood mitigation work on Bribie Island

2. Undertaking a technical assessment, using community stories and other data, to identify potential solution options for four locations.

It is important to investigate the effectiveness of different options to reduce the risks from flooding. Some options may provide more benefit than others, and some could even make flooding worse.

This project does not include funding for infrastructure design or construction. Once we have identified cost-effective solutions, we will seek funding from the State and Federal Governments to start design and construction. This may include new or improved flood mitigation infrastructure, including drainage.

We know other areas are also impacted by flooding and we will continue to manage those risks.

The identified areas have clusters of buildings with what planners call "intolerable risk" of flooding. The risk level may be considered intolerable either because it experiences frequent minor flooding, or occasional significant flooding.

These areas were identified by reviewing flood data across the whole City of Moreton Bay.

Other areas requiring flood mitigation work have also been identified in other parts of City of Moreton Bay.

Flood affected areas across the entire City have been prioritised for assessment over the coming years

It’s important to investigate all the possible options to reduce flood risk. Some options may work better than others. Some may even make the problem worse, or just move the flood water to another community. This study aims to identify cost-effective solution to reduce the impact of flooding to homes and businesses in the identified priority areas.

Council takes a proactive approach to managing known flood issues within the region. Council is aware of a number of flood affected areas on Bribie Island, as well as across the entire Local Government Area. Council has created a prioritised list of areas with problematic flooding, and the floodplain team systematically investigates mitigation solutions (such as drainage upgrades, detention basins, levees etc) and/or flood risk management opportunities (such as early warning flood gauges) for these areas. There are a number of areas in the Moreton Bay Local Government Area which are on this list, and it does take time and financial resources to identify the correct solution and implement it.

    Options chosen for further investigation

    We will let you know which flood mitigation infrastructure options will be further investigated.

    Construction of infrastructure is dependent on funding provision.
