Landscapers turf out water-guzzling plants

Emerge Associates senior landscape architect Shane Caddy is the brains behind the landscaping design on Marmion Avenue, near Butler Boulevard, which uses native plants rather than lawns.

The Department of Water is reviewing the groundwater allocations for irrigation purposes throughout Perth’s northern coast with the view to decreasing irrigation by a minimum of 10 per cent.

‘The ratio of turf to planting beds has switched dramatically, with planting beds increasing due to increasing water restrictions and the need to create more habitat locations for the black Carnaby’s cockatoo,’ Mr Caddy said.

‘Native plants are typically accustomed to the nutrient-deficient soils found on the Swan Coastal Plain which reduces the need for the use of fertilisers which can add nutrients to our waterways and groundwater resources.’

Mr Caddy said inspiration for landscaping themes in Satterley Property Group’s Brighton Estate came from its location.

‘To create a coastal, chic feel that is fun and vibrant we have used colour throughout each village as a subtle way to create difference,’ he said.

‘The closer the project develops closer to the coast the more you will see the planting palette change to suit the increased salinity levels and sand-laden winds.’

The estate has WA native peppermint trees throughout streets and parks, chosen for their shade and tolerance of salt and sand-laden winds.

The landscapers have put deciduous trees such as flowering pears and Chinese elms around the Brighton district centre and Butler train station to reduce the effects of the heat radiation from hard surfaces.
