Works on dog beach hit a snag

DOG Beach's $1.6million stage one restoration has struck a serious snag that has called a halt to the Noosa River project, which began on September 26.

The tender dredge brought in to help repair years of unchecked erosion on Noosa Spit (which claimed 30m to 45m of the beach and spit in a three year period) has found the going much harder than expected.

And the problem is deeply rooted in all that subsidence, which saw collapsing trees and even pathways claimed by the relentless water.

Last week, a council spokesman and councillor Russell Green both confirmed a more heavy duty dredging system was being sought to complete the necessary works, to allow for an upstream training wall, which would be about 80m long.

"Work on the first stage of the Noosa Spit dog beach erosion project has been temporarily delayed, due to a significant amount of vegetation being found below the sand shoal, that caused difficulties with the dredging," the spokesman said.

"The council is currently assessing offers from two other contractors to get another dredging contractor engaged. Work is likely to resume in early November."

Cr Green likened the unexpected delay to a home builder digging foundations expecting sand and hitting rock debris.

He said the council was determined to get on with the job that 1045 petitioners demanded it carry out to save a popular recreation area.

The council said the first part of the work involved construction of the submerged channel closure, immediately upstream of the existing rock wall near the area of dog beach.

Work was to begin in August, but due to technical delays finally started with the removal of dead vegetation and broken concrete paving in late September.

The dead vegetation is to be mulched and used for restoration of disturbed areas on the spit.

The council said the reason for the works was the "alarming erosion between 2006 and 2009", which saw 30m eroded at Dog Beach, and 45m at the upstream end of Noosa Spit.

The artificially created peninsula of the Noosa Spit, which protects Noosa Sound from the sea, was eroding at a rapid rate and the council feared a possible eventual breakthrough, exposing properties to currents and wave action. After stage one, the council will monitor the effectiveness of the work for two years to determine if additional works will be required.
