TENDERS have been called for what Sunshine Coast Council hopes will be a permanent erosion fix for Noosa Spit.
Prospective bidders will get a better understanding of what council requires this Tuesday at a 10am project briefing at the Tewantin council chambers.
Council recently put the call out for someone to build a “submerged channel closure, a revetment wall and groyne/training wall using sand-filled geotextile mega-containers”.
The council contract would also include dredging works and foreshore nourishment to stop dramatic losses of sand – 30m in three years at Dog Beach and 45m at the upstream end of Noosa Spit. Stage one has been estimated at $1.6 million.
After deciding to adopt the International Coastal Management proposed solution, council had hoped to begin the works during the low swell period of autumn/winter.
The upstream training wall will be about 80 metres long.
Councillor Russell Green is a strong supporter of the works and believes that doing nothing is not an option.
“We are faced with losing Noosa Sound, paths, roads, recreation areas and council infrastructure – doing nothing is simply not an option.
“Obviously nothing in nature is absolute, however because of the extensive hydraulic modelling that has been done in this area we can be confident that the works will result in a near-natural shoreline alignment and will not negatively impact areas further up or down the Coast,” he said when first announcing the project commitment.
“A thorough monitoring program will measure the need to move to stage 2 works and allows a flexibility in the approach council uses to progress the project past stage 1.”
Stage two would involve building two groynes and foreshore renourishment.
