The City's response to PerthNow about the installation of synthetic turf on street verges, 13.9.24
The City’s Street Verge Improvement Policy states that approval is required for synthetic turf or hard surface treatments where more than 25 per cent of the verge is paved. Verges with hard paving or impermeable areas (such a synthetic turf) must demonstrate mitigation of the urban heat island effect through street tree planting or landscaping and verge permeability (the use of soil to allow water to soak away).
The City doesn’t support the application of synthetic grass to the entire verge as it can increase water wastage and run-off, and contributes to the urban heat island effect as it can reach up to 100 degrees on a hot day. This increases the air temperature in the vicinity, which is worsened if the area is unshaded. Synthetic turf also destroys any biodiversity in the soil through the heat it generates.
Where a mature tree exists on a verge, the installation of synthetic turf often requires soil heights to be lowered, resulting in damage to tree roots which can cause the death of mature trees.
Utility providers which house their services within the verge space will remove artificial turf if access is required and won’t necessarily replace the turf at completion of works.
The Policy has been in place for more than a decade. It has not been the subject of significant complaint and certainly not in recent times. Any complaints over the years have been dealt with on an individual basis where the City works with the complainant to find a solution. The City does not patrol verges for non-compliance.
The City has several initiatives to help with improving street verges:
Waterwise Verge Rebate – Waterwise Verge Rebate provides eligible applicants with financial support for Waterwise verge installations. Applicants have free access to professional verge designs, and these include a list of plant species. This rebate runs for a limited time to utilise seasonal rainfall.
Native Plant Subsidy Scheme – Provides residents with the opportunity to purchase subsidised native plants in May each year.
Sustainability Grants – Collective (2 or more) households can apply for funding for Waterwise verge improvement projects, up to $4,000.
Grow Local Brochures – Enables residents to select the right plants for their area and soil type.
Garden workshops – these provide advice on verge design, composting, food gardening, Waterwise plants and tips.
Bird Bath Rebates – up to $50
