Response requested:
Please provide:
    1. clarification of the number of groynes proposed. The Basis of Design report prepared by BMT
       and dated 2 April 2026 assess the functional requirements and design data is based on four (4)
       groynes recommends four groynes, however the plans of the development indicate only three (3)
       groynes are proposed
    2. information that demonstrates the proposed structures will achieve the geomorphic stability
       required to protect existing significant infrastructure on adjacent lots
    3. a revised coastal processes report and modelling outputs for the works with three (3) groynes as
       per the design as shown in the plans. The report should demonstrate:
            a. how the structure has been designed to minimise impacts to coastal processes
                 (sediment budget/ transport pathways)
            b. potential impacts on adjacent neighbouring sites from downdrift impacts
            c. how the structures occupy the minimum footprint feasible to effectively fulfil the
                 function of the structure, and provide information on the design of the structure
                 including justification of the varying groyne lengths, and
            d. a demolition plan for the existing rock revetment, as demolition of a tidal work is itself
                 a tidal work. The plan must identify the current property boundary and include tidal
                 planes (highest astronomical tide (HAT), mean high water springs (MHWS) etc.) to
                 demonstrate the location of the works in relation to the tidal environment.

2. State code 8 – PO16 Public use of and access to state coastal land
In reviewing the application material, it is understood that the reconstruction of the revetment wall is
intended to be wholly located on private land, however the plans do not reflect this. The two resorts are
located on strata parcel land (Lot 0 on BUP4021 and Lot 0 on BUP9869) with an ambulatory boundary. A
recent Identification Survey, dated 18/06/2026, confirms that the existing revetment wall extends 0.25m -
1.5m outside the property boundary onto state coastal land. Any replacement or reconstruction works
should be wholly contained within the boundaries of the freehold land and the use of state coastal land
justified and minimised to the greatest extent possible.

Response requested:
Please provide revised engineering plans (site and cross-sections) that:
   (a) clearly locates the revetment within the same lot as the building it is intended to protect
   (b) illustrates the groynes ‘attach’ to the freehold boundary
   (c) include:
         i. the location of all built structures, or structures to be modified or demolished, as a result of the
            proposed development
        ii. adjacent riverbanks, walls, sandbanks, structures, the limit of vegetation, and/or other principal
            features of the immediate area
       iii. relevant tidal planes (e.g. HAT, MHWS)
       iv. the location and setting out details for cross-sections
        v. any other information required to accurately define the area and to allow the site to be readily
            identified from the plan.

Property boundaries must be shown on all plans. All plans/drawings should include title, date and
numbering suitable to identify the plan and should be mapped to GDA2020 projection.

In accordance with s51(3) of the Planning Act, 2016, this development application is taken to be an
application for an environmental authority under the section 115 of the Environmental Protection Act 1994
