Noosa holds the Spit erosion line in costly battle
NOOSA is destined to be forever "throwing money" at its river mouth to help protect exclusive Noosa Sound properties.
That is according to Mayor Tony Wellington, who said it was unfortunate but true that "we'll be forever playing catch up here, because the natural river mouth has been so altered".
"It can no longer behave in the way nature intended it," Cr Wellington told the general committee meeting while discussing the latest report on the Noosa Spit shoreline erosion management plan.
The council has major concerns about the impact of a spit break through on Noosa Sound properties and has sought legal advice on possible future litigation and ways to mitigate the risk.
"We now have a situation where the river mouth wants to do what it traditionally should be doing and that is moving up and down the coast," Cr Wellington said.
"And instead we're trying to keep it in one place, trying to train it. The end result is that we will be forever throwing money at our river mouth and main beach, because we've created and artificial situation there."
The mayor said the area would require ongoing repair, as changes done in one section of the river mouth system had an impact elsewhere.
He said the previous measures put in place to protect Doggie Beach by Sunshine Coast Regional Council were "going to inevitably have all manner of repercussions which we are only gradually discovering".
"I accept that in the past dredging etc, was considered to be an appropriate response.
"It would be nice if we were gathering greater information about how to deal with dynamic systems like river mouths so that in the future we can spend less money on trying to control mother nature."
Cr Ingrid Jackson said it was important to have an expert report on this erosion problem, while Cr Joe Jurisevic said the council needed to look for the most ideal solution rather than relying on ideas of the past.
"It may be that we resort to the same sort of thing, but I await the shoreline erosion management plan with bated breath," Cr Jurisevic said.
"Trying to find a solution to this for the long-term will be a challenge."
Cr Frank Pardon said he was against rock walls and believed a previous Noosa Council had the right idea by creating sandbank protections through pumping.
Cr Brian Stockwell said the shoreline erosion management plan study would help the council to understand the flow-on effect of interventions, while Cr Jess Glasgow said the work done on Main Beach showed "we can bring the sands back".
"Hopefully in the future we will save Noosa Pde."
