This Practice Paper identifies and critically examines three alternative approaches and associated design philosophies in response to the problem of urban flooding. It traces the reasons why these three approaches have emerged and discusses the attributes of each. Following this, it examines the potential of the green infrastructure approach as a means to realize ‘evolutionary resilience’ in designing urban environments for enhanced drainage management. The paper then contrasts the three alternative approaches to flood risk management and identifies some implications of advancing the green infrastructure concept in urban design activities
