EXECUTIVE SUMMARY
Not applicable.

RECOMMENDATION
That Council note the report by the Project Coordinator – Flooding, Coastal and Foreshore to the
Services & Organisation Committee Meeting dated 6 November 2018 and support the completion
of a Shoreline Erosion Management Plan for Noosa Spit and Noosa Main Beach subject to
funding being provided in Budget Review 2.


REPORT
1.                       Background

In May 2018, Council received an update report on the erosion at Noosa Spit Foreshore/Noosa
Dog beach. Following that meeting, Council applied for grant funding for a Shoreline Erosion
Management Plan (SEMP) through National Disaster Resilience Program (NDRP) funding.
However, due to the large number of competitive submissions for this grant, Noosa Council was
unsuccessful in obtaining funding within this funding round.

Council staff have continued to closely monitor this coastal erosion hotspot and conducted a
detailed shoreline and bathymetric survey in July 2018, for comparison with a similar survey
conducted in July 2017. The results of this survey show an overall loss of 19,586m 3 of sand
along the foreshore. A review of aerial photography shows a shoreline recession of up to 13m
between September 2017 and 2018, which adds to the 16m experienced in the previous year.
This erosion is continuing despite the opening of the central channel (Shown in figure 1, below)
and the presence of the fallen trees, which should provide limited protection to the shoreline.
