Broadwater Parklands – Stage 3

Broadwater Parklands - Stage 3

Burchills were engaged by the City of Gold Coast Council undertake concept planning, assessments, investigations, planning and detailed design of the Southport Broadwater Parklands Stage 3. Coastal / Marine, Civil and Environmental Engineering for the proposed coastal reclamation area, rock revetment, seagrass translocation, access roads, 120 car parking spaces, four lane boat ramp, finger pontoons, parking facilities to accommodate 90 boat trailer parking bays and a floating jetting.

In collaboration with other consultants, Burchills provided design input and was responsible for gaining the necessary local and state government approvals associated with the reclamation elements of this project. This project involved widening an eroded section of foreshore to create a larger and more functional recreational asset of the local community. This was achieved through the dredging of local marine sediments from within maritime navigation channels, to reclaim around 1 ha of newly created foreshore. The reclamation created large areas of open grass land, fringed by coastal dunes areas. Pedestrian/bike walkways were also constructed as part of the Gold Coast’s “Oceanway” network. Burchills together with the project team designed the foreshore upgrade to ensure flood impacts were minimised and foreshore treatments where stable. All necessary approvals were obtained from various state assessment agencies along with construction environmental management.

Burchills have been involved in a number of elements and stages of this master planned parklands which has been developed over the past decade. Some of the relevant projects are described below.

Stage 3

Burchills were engaged by the City of Gold Coast Council undertake concept planning, assessments, investigations and detailed design of the Southport Broadwater Parklands Stage 3. The scope included the design of coastal reclamation area, rock revetment, seagrass translocation, access roads, pathways,revetments, 120 car parking spaces, four lane boat ramp, finger pontoons, parking facilities to accommodate 90 boat trailer parking bays and a floating jetting.

The proposed reclamation areas required the existing stormwater piped drainage and outlets to be relocated including a trunk 1350mm diameter stormwater pipe which was redirected through the development in order to locate the stormwater outlet beneath the fixed landing platform component of the floating jetty. Provision was made for the stormwater runoff from the proposed roadworks and car parking to be treated within bio-retention basins.Flood modelling was also undertaken utlising 1D/2D TUFLOW program to ensure no adverse impacts result from the proposed works within the coastal floodplain.
