Broadwater Parklands

In collaboration with other consultants, Brad Comley from Burchills Engineering Solutions has been involved in the design of a mangrove offset as part of the Gold Coast Broadwater Parklands Project.

In order to offset marine habitat losses associated with reclamation aspects of the project, a 1.2 hectare mangrove wetland is in the process of being created. The mangrove wetland has been designed to improve the quality of stormwater discharged into the Broadwater and increase the diversity in marine habitat within the Southport Parklands. Newly created yabbie banks and sea grass beds will also help to compensate for direct losses of similar habitats.

Surface levels and profiles have been established and rehabilitation (fabrication) works are currently being undertaken through propagule and seedling installation. This involves a combination of the collection of mangrove propagules from within the local area and the translocation of seedlings from the port of Brisbane. Propagules and seedlings are installed by hand, directly into the newly created substrates.

When finished, the mangrove will add to the Broadwater Parklands ecological and recreational values.
