A SEA wall is one of the long-term options being considered to address severe coastal erosion in Seabird.

Shire of Gingin chief executive Jeremy Edwards said they were working with the Department of Transport and landowners on short and long-term solutions.

‘Some of the long-term options that have been presented to the Shire are sea walls and groynes, but no decision has been made,’ he said.

‘We are consulting with Seabird residents and Department of Transport coastal engineers.

‘The solution is complex and meetings on this are regular.’

The Times understands at one of the meetings, property owners were shown funding options for the sea wall, estimated to cost $700,000.

Presuming the State Government provided half the funding, those options indicated it could cost individual landowners between about $16,500 and $70,000, depending on how many of the 15 affected properties contributed, and whether the Shire helped to fund it.

It also outlined a potential specified area rate levy that could be applied to 311 properties in Seabird, collecting either $250,000 or $350,000 over one or two years.

In July, the Shire poured 3000 cubic metres of sand on to the beach at the end of Turner Street as a $110,000 emergency coastal protection measure.

‘This sand nourishment is aimed at protecting this asset and so far is holding up well,’ Mr Edwards said.

He said the Shire had received a grant from the Department of Planning to undertake coastal hazards risk management adaptation planning for its entire coastline.
