View the 7 concept designs
We are asking you to consider the seven concept design options for coastal protection.
All seven options will be designed to withstand 100-year ARI design conditions and are expected to offer similar levels of erosion protection.
How the different options perform under different scenarios will only be known once detailed testing is done in the next phase.
PLEASE NOTE: The aim of this project is to consider the alignment and the type of structure that will best protect Byron Bay from coastal erosion. Once we have decided the future position of the structure, Council will work with the community to plan what may lie landward of the protection works. Car parking, recreational areas, pedestrian paths and a combination of these are possible under all 7 concept design options.

- An eighth concept was considered and assessed against the project criteria and objectives but was not feasible. See the consultant's Assessment of Alternative Option 8.
This concept is largely based on the preferred option that emerged in the 2014 investigation. It shows:
- all three groynes removed
- reconstruction of the sloping rock seawall
- a stepped concrete seawall in the popular high-use area.
By removing the groynes, this concept would create an uninterrupted shoreline and improve people’s connectivity along the beach in front of the structure.
This concept is similar to Option 1 with the groynes removed, however with a berm structure in front of the current carpark. Being closer to the water’s edge, this sloping rock seawall (berm structure) creates space for people to walk along a shared pathway at beach level.
This concept shows removal of the two short groynes and a small part of the main central groyne to create a ‘detached groyne’. This would create an uninterrupted shoreline and enable people to move all the way along the beach, while still keeping the main groyne which is perceived to provide benefits for surfing.
This concept replaces the central groyne with an artificial rounded headland offering more public space, protection, enhanced foreshore amenity and potentially enhanced surf amenity. This option would be combined with a small scale sand by-pass system built into the headland to increase sand movement from east to west.
This concept considers the reconstruction of the structure in a more landward position by 10m and removes all three groynes. The landward shift would still allow car parking as well as a shared pathway corridor while protecting the entire pool site. Options for the protection structure would be further explored once feedback on the alignment and key design elements are received from the community. However, it is envisaged that a vertical seawall would maximise beach space. It is noted that a boardwalk could be placed seaward of the protection structure to provide additional recreational foreshore space.
This concept considers a more significant shift landward of up to 30m in places. It is not based on retaining existing assets but looks at the ‘bigger picture’ of offering maximum protection to Byron Bay town centre while achieving the best result in terms of maximising beach space. This approach removes all groynes with full realignment of the structure landward and creates an uninterrupted shoreline and wider beach. This option is the most relevant option that aligns with the principle of keeping the beach as much we can while providing the greatest long-term protection. It is noted that a boardwalk could be placed seaward of the protection structure to provide additional recreational foreshore space.
This concept retains the existing structure and groynes repairing it to a contemporary standard. This approach is based on maintaining the status quo.
