Protecting Narrowneck for the future

9 June 2017

Narrowneck Beach will be better protected as works to replenish the artificial reef and extend the seawall begin in coming weeks as part of the $18.5 million budget for coastal protection projects (2017-18).

The artificial reef, originally built in 1999, has increased the resilience of Narrowneck against the impacts of storm events and large ocean swell. 

Mayor Tom Tate said the $2 million renewal works, commencing in August, involved placing additional geotextile sand containers on the existing artificial reef using a specialised vessel. 

“The existing reef has helped protect the beach for the past 17 years. Now we need to ensure this coastal protection continues in order to retain sand on our northern beaches,” he said.

“The artificial reef lessens the erosion impacts of large waves. As these waves cross the reef, their intensity becomes less threatening to the beach. The reef promotes a build-up of sand to act as a buffer to protect the beach during storms.”

An additional 200 metre section of seawall will be renewed just south of Narrowneck at Higman St, Main Beach, at a cost of $900,000 with works commencing in July. This will complement the existing $4.2million, 600 metre seawall at Narrowneck. 

Mayor Tate said the City’s seawalls had a long and proven record of beach protection on the Gold Coast.

“Seawalls are the preferred and endorsed option as a hard coastal protection measure. They have a geotextile filter layer which prevents the leaching of sand through the seawall and they’re designed to move under wave attack,” he said.      

Works to upgrade the popular Narrowneck Oceanway along Marine Parade at Main Beach and the construction of a new amenities block are also underway.

“We are installing a new five metre-wide concrete path; viewing platforms, a picnic shelter, beach showers and benches, with a total project cost of $1.8 million,” said Mayor Tate.

“We’ve allocated $18.5million this coming year for coastal protection. Our next major projects are the Gold Coast Beach Nourishment Project and the Palm Beach Shoreline which begin this month with the arrival of a large dredge to start beach nourishment works.”

Narrowneck reef renewal is a joint initiative of the City of Gold Coast, the Queensland Government and the Australian Government. The project is partly funded through the Natural Disaster Resilience Program, a joint State and Australian Government funding program.

Both the Narrowneck reef renewal and seawall works are due for completion by December 2017. The section of Oceanway path and amenities block will be completed in September.
