THE City of Wanneroo Council will consider a report on beach access in Two Rocks at its next meeting.

The council referred the report back earlier this month for further information from consultant MP Rogers and Associates.

The April 4 report recommends the council accept the second option for stairs at the northern Sceptre Court location, where the previous stairs were.

The recommendation also asks Mayor Tracey Roberts to seek an urgent meeting with Transport Minister Rita Saffioti and Butler MLA John Quigley to discuss funding and long-term solutions to coastal erosion north of Two Rocks Marina.

“Costs for the detailed design and construction of the recommended beach access structure and viewing platform will be approximately $250,000,” the report said.

“Actual design and construction costs are subject to market conditions at the time of tendering and therefore may vary with the concept-level cost estimate.

“Currently $400,000 is listed for consideration in the draft 2017-18 Capital Works Program.”

The Two Rocks Beach Action Group has advocated for a modified octunda structure that incorporates a viewing platform if more funding is available, but the report said a staircase remained the preferred option.

“Based on MP Rogers concept-level cost estimates, the Modified Octunda option is expected to cost approximately $600,000,” it said.

“Without consideration of the cost criteria in the multi-criteria analysis, northern locations option 2 remains as the preferred option in the technical assessment undertaken by MP Rogers, due to low environmental impacts and community support.”

The report said its benefits included being at the location preferred by most residents, existing infrastructure such as parking, a shower and concrete path, plus that the solution would account for ongoing erosion issues.

“MP Rogers have based the setback distance of the staircase on five years of shoreline retreat, plus storm-induced erosion for an extreme weather event,” it said.

“The recommended staircase material is fibre-reinforced plastic due to the benefits associated with durability, design life and maintenance – this material is also more fire-resistant than timber.”

The report said all foundations of the structure could be piled into bedrock for long-term stability, provided there was ongoing maintenance.

At the March 28 council briefing session, coast projects manager Rory Ellyard said the stairs would have a functional design life of 15 years, although it would have a 25-year structural design life.

“It may need to be closed seasonally like the previous staircase was,” he said.
