A Stanmore Bay homeowner is investigating whether a large sinkhole and subsidence in her backyard could be connected with the Mariner Rise subdivision on Link Crescent, behind the property.
The subdivision was completed by McConnell Development at the end of 2017. It included building a large retaining wall behind homes that overlook the site, in Elan Place. Properties there got a small bit of extra land, which was backfilled to make the wall.
Lynne Davidson has lived in her Elan Place home since the end of 2014. She says when the retaining wall went in, especially the piles, her house shook.
She says a few months later she noticed a gradual sinking of one corner of her back garden. An apple tree is now leaning to one side.
The 76-year-old says things got worse recently, including cracks in the soil and paving, and more slumping.
The week before Easter, her shower, bath, sink and toilet all began filling up with water.
Plumbers discovered a hole around 2m wide and deep beneath the pipe in Lynne’s garden. Lynne says fixing the problem is proving expensive and may cost her several thousand dollars.
She is contacting McConnell Development outlining the problem.
The company’s senior development manager, Matt Anderson told Hibiscus Matters that once they hear from Lynne, they will investigate.
