The detailed design was endorsed with changes at the March 2025 Ordinary Council Meeting. This project informed Council as to how to best prioritise drainage upgrades that target existing deficiencies in the drainage systems.
The project reviewed the preferred Byron Drainage Strategy, and developed a plan that aims to reduce the risk of flooding in the town centre.
Construction is expected to start in mid-2025. Further information about construction will be provided in the coming months.

History of flooding
Byron Bay has a history of flooding during heavy rain, and this affects businesses and residents. It is further compounded by:
- low terrain
- ocean levels
- Belongil Creek
- Belongil Creek floodplain.
Funding

Drainage upgrades
We have received funding for the construction Town Centre Catchment and the Recreation Grounds Catchment.
- $7M for gravity drainage upgrades in the Town Centre Catchment, has been jointly funded by the Australian and NSW Governments through the Infrastructure Betterment Fund.
- $11.8M for gravity drainage upgrades in the Recreation Grounds Catchment has been funded by the Australian Government through the Emergency Response Fund administered by NSW Reconstruction Authority’s Northern Rivers Recovery and Resilience Program 22-23.
We will need additional grant funding to complete construction of the remaining stages.
Staging
The upgrade to drainage will require construction to be staged. The Town Centre Catchment design is Council's first priority, followed by the Recreation Grounds Catchment.
The detailed design for The Town Centre Catchment is complete and an Expression of Interest (EOI) was issued in December 2024, to find a suitable construction contractor to do the work.

We have upgraded the drainage and road on Lawson Street to integrate into the Byron Bay Drainage Upgrade.
Once the drainage is upgraded it will improve the quality of water that ends up on Clarkes Beach.
