Wanneroo City councillors will consider the report on a revised design at their meeting tonight, April 2, which said shoreline erosion and the rock location meant a previous design of concrete steps was not suitable.
It said a consultant found the design endorsed by the council in May 2012 was no longer suitable as more sand erosion had occurred since the original concept was prepared and a survey had shown the rock layers more accurately.
‘The proposed concrete staircase has been replaced with a light weight aluminium supporting structure with fixed fibre reinforced recycled plastic step treads,’ it said.
‘The revised beach access structure is considered to be more sustainable and flexible, and will allow the City to modify it at minimum costs in the future should adjustment be required to accommodate the constantly eroding shoreline.’
The City had budgeted $119,600 for the project, but according to the report, the revised design would require an additional $36,903, which could be covered in the 2013-14 budget.
If elected members endorse the revised design tonight, residents will be sent details of the changes and a questionnaire.
‘As the beach access structure has changed from its original intent, it is intended to letter drop those residents that had originally been advised of the proposed works,’ the report said.
At last week’s briefing session, March 26, infrastructure director Dennis Blair said if the City received negative responses during public consultation, it would go back to the council, but if feedback was positive, they would proceed with seeking development approval from the WA Planning Commission.
