Serpentine Reserve BMX track temporarily closed

Serpentine Reserve BMX track is temporarily closed after building materials removed from the site yesterday, and tested today, were today found to contain asbestos.

The City of Onkaparinga responded immediately yesterday to organise its collection by the council’s licenced asbestos assessor and removalist, after a quick-thinking resident notified the council of building material fragments found near the BMX track.

It’s unknown how the material came to be at the site, though it’s thought to potentially be long-ago illegally dumped material that was unearthed by contractors ahead of works to improve the bike jumps.

Council and community works to shape, improve and maintain the site’s dirt bike jumps – through the council’s Community Dig Days initiative – took place on Tuesday 16 December, but the materials weren’t identified at that time.

Soil for the dig day was tested before being delivered to the site, and the test results advised the material was suitable for use.

The council has temporarily closed the BMX track with bunting today, and is installing signage out of an abundance of caution. Temporary fencing will be installed onsite on Wednesday 24 December. The council is also reaching out to participants involved in the 16 December dig day.

The EPA is aware of the situation, and council will share more information as the remediation works progress.

This program is all about fixing and maintaining the jumps that are already here. It’s NOT a full rebuild or upgrade. So:

  • No new jumps will be added, but we will reshape and adjust the current ones to make them safer and better to ride.
  • There won’t be any new extras like benches, lights, or toilets.
  • No trees will be removed.
  • All changes will stay within the current area – no big changes or extensions.
