5 Conclusion

  ̶
The proposed works have been necessitated to address ongoing erosion issues affecting the Noosa
Harbour and Las Rias foreshore. Revetment wall reconstruction and burial is required to ensure an
appropriate terminal structure is in place to protect the foreshore while still maintaining appropriate
public access, thereby requiring a combination of revetment wall works, dredging, groyne construction
and beach nourishment.

Assessment of the receiving environment indicates that the works can be undertaken with limited and
manageable environmental impacts. Dredging will target clean sandy sediments and, subject to
standard environmental controls and pre-dredging investigations, is not expected to result in significant
water quality, sediment quality, or ecological impacts. Any disturbance associated with the works is
anticipated to be temporary and localised.

The proposed groynes and nourishment works have been designed to address the site-specific erosion
processes operating along this section of the Noosa River. The works will promote retention of
nourished sand and improve foreshore stability without materially affecting navigation, tidal flows,
channel morphology, or broader estuarine processes.

The works are consistent with the applicable planning and environmental assessment framework and
can be appropriately managed through standard construction controls and implementation of a
framework DMP. On this basis, the proposed development is considered suitable for approval.
