It has been twenty months since completion of the remediation and environmental restoration works at the rear of Balmoral Oval.

The project had two main challenges. First, to design the work to ensure the contaminates were correctly contained in the long-term, whilst making the area look natural – blending into the surrounding environment – and accessible to the public. Second, to ensure that the heavy machinery used for the project did not disturb the surrounding bushland.

At completion of the earthworks there were several achievements:

  • The areas surrounding Balmoral Oval were remediated and are now safe to use for passive recreation.
  • The design and construction of the project incorporated stormwater engineering requirements that enhanced the area’s landscape and ecological function.
  • Work was on time and to budget. Budget was only increased to add value to the project such as the installation of a looping walking track through the project site and a pedestrian bridge across one of the creeks.
  • The project has created immediate habitat for local flora and fauna species and has created the foundation for a long-term sustainable natural ecosystem.
  • The bushland surrounding the site was not disturbed.

The site is now well and truly settled and there have been no defects in the earthworks. It is also pleasing to report that:

  • There are frogs present in the sediment ponds built into the stormwater lines which can be heard during the day and night. Tadpoles are also frequently spotted swimming in these waters.
  • The vast majority of the vegetation planted on the site including the macrophytes and terrestrial vegetation species have established.
  • The site is covered in Angophora costata seedlings derived from the remnant mature specimens surrounding the site.
  • The threatened plant species Acacia terminalis subsp. terminalis (Sunshine Wattle) and other local species have colonised the site on their own.
