READ NOWMr Winchester said he did not know about plans for a retaining wall with a 1.8m fence adjacent to their properties until it was too late.
‘It will be the equivalent of a two-storey house,’ he said. ‘Mirvac argue that it has to be built up for the topography of the development, but what about our topography?
‘We want it built at normal level.’
Ms Richards said the wall and fence would be like a huge mountain, blocking out the light. She said her property would be devalued.
Mr Wincherster plans to make a deposition to Mandurah Council on March 25.
A Mirvac spokesman said the Overall Development Plan (ODP) was approved by the WA Planning Commission (WAPC).
‘Mirvac documented and submitted all plans necessary to WAPC and the City of Mandurah,’ he said.
‘The City fulfilled public notice and public comment requirements prior to endorsing the ODP.’
The spokesman said works adjacent to existing properties on Vanessa Road required the replacement of existing rear boundary fences to provide appropriate retaining.
‘Mirvac’s civil contractors have communicated with all residents to notify and co-ordinate the construction of new 1.8m Colorbond fencing, and in some instances due to varying ground levels, a small amount of retaining wall along the rear boundaries,’ he said. ‘
He said Mirvac had regularly updated the Seascapes Residents Association on the progress of the construction.
