PRESSURE is mounting on the City of Swan to join the growing list of Perth councils outlawing synthetic turf to protect tree canopy and combat the rising urban heat island (UHI) effect felt in residential neighbourhoods.

The call for change follows successful bans in Fremantle, Victoria Park, and Subiaco, where artificial grass has been restricted to protect public health and the environment.

Local resident Catherine Dixon claims the installation of plastic lawns ruins local aesthetics while driving up temperatures in residential neighbourhoods.

“Synthetic turf has been documented to reach temperatures over double or triple the air temperature,” Ms Dixon said.

“They’re significantly hotter than natural grass, concrete, and asphalt which can put people at risk of burns and heat-related illnesses.

“Not to mention houses that have artificial grass (almost always) have nearly zero trees.”

The City of Swan’s own urban forest plan confirms that an increase in a neighbourhood’s heat can affect people’s health alongside the health of native wildlife that live in the area.

“The EPA has noted that heat-wave related deaths in Perth could more than double by 2050 as a result of the UHI effect and climate change,” the 2022 report said.

“Green corridors and streetscapes are critical in supporting biodiversity, and mitigating heat as (Perth’s) population approaches 3.5 million by 2050.”

Ms Dixon argues the city should completely ban the use of synthetic turf and switch to alternative natural grass, plants and trees.

“The trend in new developments installing fake grass is not helping our heat island or tree canopy,” she said.

“It looks ugly, weeds still grow, it fades in colour, it doesn’t hold its shape, and it smells.

“It’s time for the City of Swan to join the list and ban its use.”

City of Swan Mayor Tanya Richardson confirmed that while the city hasn’t yet pursued a total ban, they remain firmly opposed to the trend of replacing natural surfaces with synthetic turf.

“While the City of Swan does not currently ban the use of synthetic turf on verges, it is discouraged,” she said.

“Waterwise verges with native plants and mulch increase water efficiency and stormwater infiltration, creating a cooling effect, and provide habitat for local wildlife.

“Additionally, the greening of verges can be beneficial for human health and wellbeing, improving aesthetics and saving money.

“Residents who plan to install synthetic turf must obtain permission from the city.”
