Council is planning to install two short training walls (groynes) at the outlet of the Wallin Avenue stormwater drain on the Deception Bay foreshore.
This project site is beside the Wallin Family Place Park at 2-56 Captain Cook Parade, which is at the northern of the end of Deception Bay Esplanade and south of the Wallin Avenue and Captain Cook Parade intersection.
The two short groynes are to be made of heavy-duty, marine-grade, sand-filled geotextile bags. They will extend either side (north and south) of the outfall, each for a length of approximately 12 metres, approximate width 5.4 metre and height approximately 2.5 metres.
Why is Council building these groynes?
Sand tends to build-up at the outlet resulting in organic material backing up in the drain, which decomposes and causes significant odour issues.
Council’s aim is to reduce this continual build-up of sand in the drain outfall to improve the local amenity and make the stormwater drain more effective.
The project has been approved by the Queensland Parks and Wildlife Service and is not expected to impact the values of the Moreton Bay Marine Park foreshore area, such as migratory shorebird feeding and roosting.
