Detractors of Mangles Bay Marina, Charles Lammers and James Mumme, met with Denis Grey whose bores turned saline after Port Mandurah was developed.
Greens WA Senator Scott Ludlum fears Lake Richmond, home to rare thrombolites, will turn saline if the Mangles Bay Marina goes ahead.
Mr Grey was an opponent of the Creery Wetlands redevelopment back in the 1990s and the Point Grey Marina development, which received approval earlier this year.
He discussed the issues associated with canal development with Mr Lammers and Mr Mumme.
Cedar Woods and Landcorp, trading as Cranford Pty Ltd, want to build the marina near the current Cruising Yacht Club hardstand and nearby land, which includes a Bush Forever site.
This is similar to the Creery Wetlands ” that at the time of their development into Port Mandurah by Cedar Woods ” were an internationally recognised Ramsar Wetlands site and still are.
Mr Grey lost his water bores after they went saline, when Cedar Woods began developing Port Mandurah.
‘When we bought our home on McLarty Road it had a lovely rose garden and was owned by a champion rose grower,’ he said.
‘It was fully reticulated from a water bore on the property.’
When the development started moving ahead, Mr Grey began to have problems with his garden.
It turned out their water bore had turned from fresh water to saline.
While Cedar Woods never admitted fault for the bore turning saline, they have been paying half of Mr Grey’s water bill for more than a decade.
In a letter to the Federal Environment Minister Greg Hunt, Sen Ludlum said the Port Mandurah development is a warning not to build the Mangles Bay Marina. He claimed at least 29 bores were affected.
‘Saline intrusion into the ground water occurred at least 1000m away,’ he said.
‘Given the nearest canal in the Mangles Bay Marina will be 450m from Lake Richmond, there is a clear risk of similar saline intrusion.’
Cedar Woods state manager Stuart Duplock has promised to monitor the water quality before, during and after construction.
He said they have successfully monitored the bore water in all of their developments.
Mr Duplock said the proposal had undergone ‘the highest level of public scrutiny and an exhaustive assessment of the environmental issues’
‘We look forward to the Mangles Bay Marina delivering significant social and economic benefits by providing tourism, recreation and low-cost holiday accommodation facilities to all,’ he said
Mr Hunt is expected to make a final decision on Federal environmental approval of the project within weeks.
