Whitepaper: Permeable Pavement and Stormwater Management by Porous Lane

Permeable pavement is an increasingly critical technology for sustainable urban water management. With mounting challenges in stormwater control, urban flooding, water quality, and waste management, permeable pavements provide a multifunctional solution, reducing runoff, filtering pollutants, supporting urban greenery, and, in some cases, closing the loop on problematic waste streams such as end-of-life tyres. This white paper synthesises evidence from several national and international studies and field trials, with a focus on the performance of Porous Lane's permeable pavement systems in Australia. It provides a review of hydrologic, environmental, mechanical, and economic outcomes, as well as policy implications for integrating permeable pavement into modern cities. Recent climate risk and stormwater management frameworks emphasise the importance of permeable pavement in adaptation to increased rainfall variability and urban flooding due to climate change. National and state guidelines (ARR4.2, Victoria 2025, South Australia) now explicitly encourage or require the adoption of such LID/WSUD measures in new developments (Australian Government, Department of Home Affairs, 2018; Water Sensitive SA, 2021).
