The report’s recommendations are designed for simple and realistic implementation by planning authorities and developers across a broad range of uses, including office, industrial and residential developments.
Proposed changes include increasing canopy cover, maximising areas of irrigated vegetation and setting planning controls on the amount of water-resistant surfaces. These changes can contribute to a 75 per cent reduction in stormwater runoff compared to current standards.
Sydney Water Managing Director, Roch Cheroux said the report showcases the smart planning techniques that will guide development across Western Sydney and other growth communities, reducing the Urban Heat Island Effect through more effective design principles and catchment management.
“The report was commissioned to help influence the design of buildings, open spaces, streetscapes and green corridors to deliver a true Parkland City, in what is currently one of the hottest and driest parts of Greater Sydney.
“The best practice examples from across Australia challenge the business-as-usual approach, and show how landscape-led design, which captures and uses all water resources, is both achievable and realistic.
“Furthermore, implementing cooling actions such as permeable surfaces, tree planting, vegetation and irrigation will provide welcome relief to communities in Western Sydney, with modelling showing the number of extreme, very strong and strong heat-stress days per summer, decreases dramatically from 47 to 19 days.”
