A developer has been fined $100,000 for storing sand on a conservation wetland near Kwinana.

Mammoth Construction Pty Ltd pleaded guilty to breaching the Planning and Development Act 2005 in the Rockingham Magistrates Court recently.

The company admitted to breaching the conditions of subdivision approval and developing without approval for the storage of bulk sand in the conservation wetland off Treeby Road, known as Sandy Lake.

Along with the $100,000, Mammoth Construction Pty Ltd was also ordered to pay court costs of $3093.

City of Kwinana Chief Executive Officer Wayne Jack said the result was a testament to the diligence and thorough work of the City’s Compliance and Planning teams.

“This successful prosecution also sends a strong message to other developers that the City will pursue serious non-compliance,” Mr Jack said.
