4.3 State Interests
The proposed foreshore works have been designed by a Registered Professional Engineer of
Queensland (RPEQ) to meet prevailing Australian Standards including the requirements of the
prescribed tidal works code under the Coastal Protection and Management Regulation 2017. The works
are design to provide coastal protection to the foreshore while minimising consequential impacts at the
dredging site. By taking a minimal volume of sand to a depth of 1m, there will be no material changes to
channel morphology that could otherwise impact coastal processes.

Importantly, the coastal protection works being developed is the reconstruction of the revetment wall
which will be wholly located on private land (noting the property boundary is marked by the revetment
structure); public land is not being used to protect private assets. The works will require supplement
with beach nourishment to improve their functionality and to ensure that this area of the foreshore
remains accessible to the public. In turn, beach nourishment requires groynes to ensure sufficient sand
remains on the beach. The groynes and beach nourishment, therefore, supplement the coastal
protection structure while also benefiting public access, rather than serving to directly protect private
assets.

Dredging works and marine logistics will be undertaken subject to a Notice to Mariners and associated
maritime safety arrangements to be agreed between the dredge contractor and Regional Harbour
Master.

Sand dredging is readily manageable subject to standard operational controls, as set out in the
framework DMP attached in Annex D.

4.4 Environmental Authority for ERA 16 (1) Dredging
Dredging and placement works constitute ERA 16(1)(a) for dredging 1,000 to 10,000t/yr. An
environmental assessment of these works is presented in Section 3, with no impacts to environmental
values anticipated from the dredging. This is due to dredging targeting clean sand in areas not known to
support sensitive receptors and MSES values. Sand dredging is readily manageable subject to
standard operational controls, as set out in the framework DMP attached in Annex D.

4.5 Allocation of Quarry Material                                                                            Commented [JV5]: @Daniel Wishaw /@Verity Taylor -
                                                                                                             can you confirm the dredging volume based on the
As noted in Section 2.2.2, up to 1,830m3 of dredged material will be taken from the sand shoals and          above
placed above MHWS and therefore will be subject to an allocation of quarry material. This volume of
material represents a negligible proportion of the total sand available within the lower Noosa River and
will have an immaterial effect on broader morphology and coastal processes.

Measurement of sand taken will be based on survey of the beach and groynes after construction work
as not all sand extracted from the dredge footprint will be removed from the marine environment.

Due to the lack of material environmental impact and as sand will be kept within the local coastal
system, the works are considered permissible under the approvals regime for an Allocation of Quarry
Material.
