On Tuesday 30 January,
researchers from the Griffith Centre for Coastal Management held a pubic
meeting to report on findings from the
investigation of community suggested options to improve wave quality - with
a specific focus on Kirra.
The range of options that were investigated included:
1. Modifications to Big Groyne.
2. Supplementary outlet to the north.
3. Extend the 'grid system' for dredged sand to be placed further
to
the north.
4. Realign the beach profile at Kirra.
5. TRESBP operates according to current management plans.
As well as these 5 options a series of models was also undertaken that
investigate combinations of options.
The Study made 3 recommendations:
1. That the grid system for dredge spoil locations be extended to the west
and the dredge no longer deposit sand in Coolangatta Bay. 2. An
investigation into the feasibility of constructing a supplementary sand
bypass outlet and booster station should be undertaken.
3. Kirra Point Groyne needs to be addressed. As part of this investigation,
the value of cleaning up the end of the groyne or in time removing the
groyne altogether should be considered.
Note: There was a strong agreement on recommendations 1 & 2. The community
consensus was that recommendation 3 be modified to specifically call for Big
Groyne to be extended to its pre-1996 length (+30m). A fourth recommendation
from the community was that Gold Coast City Council commission the Griffith
Centre for Coastal Management to continue its investigations.
