            requirements. It should be noted that if the PO has no relevance to the proposed
            development a response of “not applicable” and a statement as to why it is not relevant is
            required (Refer to Attachment 1 for detailed responses to PO’s).

Development Description
2.      Issue:
        The applicational material currently does not include a detailed description of the proposed
        development and a description of the existing site conditions.

            Action:
            The following material should be provided:

                     a description of the land intended to be developed, including the property address,
                      tenure, and real property description of the land
                     a description of the development methodology, including:
                          o any operational works occurring on site and expected timeframes.
                          o staging of the development if applicable.
                          o measures employed to minimise impacts to the local receiving environment
                     a detailed and appropriately scaled drawings and/or plans which clearly identify the
                      location of proposed development, including
                          o location of all built structures, or structures to be modified or demolished,
                               as a result of the proposed development
                          o adjacent riverbanks, walls, sandbanks, structures, the limit of vegetation,
                               and/or other principal features of the immediate area
                          o relevant tidal planes (e.g. Highest Astronomical Tide (HAT), Mean High
                               Water Springs)
                          o the location and setting out details for cross-sections
                          o any other information required to accurately define the area and to allow
                               the site to be readily identified from the plan.
                     photos of the existing revetment that demonstrate the need for replacement (i.e.
                      areas of structural failure). Please also note that demolition of a tidal work is
                      considered a tidal work thus please include demolition plans including design
                      drawings that clearly show what is being demolished.

            All plans/drawings should include title, date and numbering suitable to identify the plan and
            should be mapped to GDA2020 projection.

State code 11 – Removal, destruction or damage of marine plants
3.        Issue:
          Based on the application material provided, it is unclear on the area of impact to marine
          plants. This information is required to assess whether the application meets State code 11:
          Removal, destruction or damage of marine plants (State code 11).

            Action:
            Provide plans showing the area in square metres of marine plants that will be impacted by
            the proposed works. This should be accompanied by supporting information on the type of
            marine plants (species and maturity) and if the impacts are proposed to be permanent or
            temporary.

4.          Issue:
            Hard structures within soft sediment environments are considered to be a last resort option
            where no other lesser impact option is viable. This is because hard structures cause
            accelerated erosion to adjacent areas, known as the end wall effect. Replacing soft
            sediments with hard structures permanently alters the substrate and habitat, impacting the
            fisheries resources that depend on them.

            Proposals impacting marine plants must demonstrate they follow an avoid, minimise,
            mitigate hierarchy. It must first be demonstrated that all reasonable efforts have been made
            to avoid the impact (e.g. managed retreat, setting a buried revetment back from the
