Initial modelling has revealed which apartments will be exposed to “maximum” noise levels by the proposed Burswood race track, while the State’s environmental watchdog weighs up whether to launch a full assessment.

The $217 million project, that also includes an outdoor amphitheatre, has been referred to the State’s Environmental Protection Authority, which has opened a seven-day period for public comment as it decides whether to investigate further.

Main Roads WA referred the Burswood entertainment precinct to the EPA, but argued a full assessment wasn’t required under law.

EPA chair Darren Walsh said he wanted to ensure all potential impacts were identified.

“In deciding if a proposal should be assessed, the EPA considers information such as but not limited to environmental impacts, proposed management, and the number and complexity of any key environmental factors,” he said.

A major election promise, the Burswood project is fiercely opposed by some locals, the Town of Victoria Park, the Greens and the State Opposition – which has repeatedly called for it to be axed.

Supporting documents attached to the EPA referral by Main Roads WA reveal the results of preliminary testing, that found nearby residential apartment buildings would be most affected with average noise levels between 78 – 85 decibels.

While, residents on level two of 39 Bow River Crescent could be exposed to maximum levels of 91 decibels, equivalent to a power tool or tractor, during a V8 Supercar event.

The recommended safe time limit for 91dB is two hours, according to Audiology Australia.

“If this project was to fall over, it’s going to be on these noise and amenity impacts,” Greens leader Brad Pettitt said.

“(91dB) is a lot louder than living by a freeway and when you’re in a construction site you wear ear muffs and ear plugs for good reason.

“If those noise levels are going to be inside apartments then that’s a considerable amenity impact and it’s certainly going to be a lot higher for those sitting on their balconies or outside.”

The noise modelling by Lloyd George Acoustics assumed a three kilometre circuit, 67 laps per race at an average speed of 140 kilometres per hour.

The report also revealed the Government proposal is modelled on a three day V8 Supercars event, with 90-minute race durations and races Friday to Sunday during daylight hours.

The frequency of concerts at the outdoor amphitheatre is predicted to be “sporadic” and both night and day.

The Main Roads WA report stated that the Environmental Protection Authority’s (EPA) environmental objectives “can be met” and that no referral was required under law.

“The Proposal presents a unique opportunity for urban renewal and environmental enhancement in a historically degraded area,” the report said.

“With appropriate mitigation measures in place, the Proposal is not expected to result in significant residual environmental impacts.”

The referral document says no native vegetation will be cleared, but lists the loss of wetland fringing habitat, and death or injury to common fauna during construction, as potential impacts.

“A fauna management plan will be developed to relocate fauna utilising artificial habitat,” it said.

Main Roads WA says the proposal does not extend to the riverfront and will enhance the visitor experience “through improved connectivity, scenic views, and integrated public spaces” at the Burswood Peninsula.
