Total Value: $190,000

The site was located along the Esplanade in Peppermint Grove, therefore all works needed to be completed to high standard. This project involved demolition of an existing limestone retaining wall and replacing it with a limestone biscuit rock headland to provide a more stable and wider beach. Included in the headland were beach access stairs at two sites constructed from carefully selected biscuit rock grouted into position. Existing storm water drainage was upgraded with a gross pollutant trap and redirected within the headland. Finally landscaping was completed to the site including revegetation using low native plants on the crest of the headland, beach renourishment, construction of a cement stabilised limestone access track, irrigation and planting of semi-mature peppermint and tuart trees.

• Liaising with key stakeholders including the Shire of Peppermint Grove, The Department of Biodiversity, Conservation and Attractions (DBCA), The Department of Planning, Lands and Heritage, Seashore Engineering, Heritage tree arborists, Scotch College, mooring owners and local residents;
