The township of Amity Point is located at the north-eastern point of North Stradbroke Island, Queensland, Australia. The local Council engaged Water Technology (WT) to conduct a Shoreline Erosion Management Plan (SEMP) with a 20-year planning horizon. The foreshore is subject to retrogressive flow slides, while this phenomenon is not well understood, the private property owners have historically defended their properties by placing (mainly) rocks from the local quarry at the foreshore. The SEMP recognises the seawall style protection as a Flow Slide Barrier (FSB) and recommends continuous maintenance of the structure.
WT was re-engaged to scope a strategy for implementation of the SEMP recommendations. The complexity around the implementation of the SEMP is due to the many stakeholders involved, as well as inclusion of legal implications around Native Title determination and maintenance obligations of the FSB. During this process specialised disciplines such as coastal law, community engagement and coastal engineering must collaborate to cover all aspects of the plan. A technical and legal review were conducted to ensure the engineering works are feasible and suitable as well as manageable for all involved stakeholders.
More Native Title consent determinations are to be expected in the future. Which could have effect on the way Coastal Engineers have to deal with local resources and areas of cultural significance. The paper and presentation will outline how those issues can be overcome at North Stradbroke Island.
