Consultation extended on Quinns Rocks erosion management options


Two options for long-term coastal management were proposed for Quinns Beach, with one (top) to add a groyne and alter existing groynes. The other (bottom) proposed relocating the car park as well.

COMMUNITY concerns at information sessions for proposed coastal management options in Quinns Rocks have prompted the City of Wanneroo to extend public consultation.

The City held two sessions at Gumblossom Community Centre on April 27, outlining two options for long-term management of the Quinns Beach area.

Both options proposed building a fourth groyne at Queenscliff Park, north of the existing structures, which would be modified, and adding sand to the beach.

One option also proposed to relocate the car park on Ocean Drive, remove the toilet block – which last month had mosaics installed – and revegetate the dunes.

Consultants Cardno prepared the Quinns Beach Long Term Coastal Management Study report for the City after assessing potential coastal management options address ongoing erosion at Quinns Beach.

“Erosion and coastal management has a long history at Quinns Beach; early anecdotal evidence suggests that Quinns Beach has been experiencing erosion since at least the 1940s,” the report said.

It said the option to relocate the car park 30m south of Fred Stubbs Park was preferred because of its “low capital and maintenance cost, and the alternative amenity provided”.

The option to extend the three existing groynes ranked second “due to its predicted ability to best protect” the car park and dog beach.

Assets director Harminder Singh said the sessions provided information on two proposed long-term management options for the Quinns Rocks coastline.

“Attendees were provided with information and plans for the two options and invited to ask questions,” he said.

“Attendees requested additional time to review the newly released draft stage two study report and so the deadline for community feedback to the City was extended to Friday, May 13.

“This extension has been advertised on the City’s website, Facebook page and in local newspapers.

“A detailed summary of the community’s feedback will be prepared after the extended feedback period closes.

“The community’s feedback summary will be posted on the City’s website on May 20 and posted out to all attendees who registered their address.

“Community feedback will be considered during the council’s decision making process and during the detailed design stage of the project which will follow.”

The City also recently invited comments on the first part of its Coastal Hazard Risk Management and Adaptation Plan, prepared by MP Rogers and Associates.

The study analysed the potential impact of sea level rise on the City’s coastline and identified residential areas, infrastructure and assets that may be at risk of being impacted over the next 100 years.

It held a community information session in Two Rocks on April 20 and will hold another at Anthony Waring Clubrooms, Clarkson from 6pm today.

At its April 5 meeting, the council agreed to advertise a draft coastal assets planning policy based on that study for a 42-day public comment period, which started on April 8.

Acting planning and sustainability director Mark Dickson said was advertised for 21 days in error, and the City reopened the public comment period today, extending the closing date to May 31.

At the same meeting, it agreed not to proceed with a feasibility study for an ocean pool in Quinns Rocks because the recommended location was “not connected to existing or proposed coastal structures”.

A Cardno location assessment included in the April 5 report said an ocean pool would not contribute to erosion management measures.

On April 26, the council awarded a three-year contract to Carramar Resource Industries to supply and delivery sand to Quinns Beach.

Works to be undertaken this month (May) were expected to cost about $140,000 and be partially coverd by a Transport Department grant.

“Anticipated annual beach re-nourishment costs are $50,000 to $250,000, depending on the volume of sand required at the time of the works,” the council report said.
