Advances in the Integration of Sustainable Drainage Systems into Urban Planning: A Case Study

Climate change is arguably the greatest challenge facing cities today. Its severe consequences have created the need for sustainable urban planning. In this regard, Sustainable Drainage Systems (SuDS) have contributed in recent years to alleviating environmental problems caused by soil sealing and enhancing the resilience of cities to climate change. However, in most cases, the level of implementation is limited to solving environmental problems caused by inadequate urban planning. To change this, in recent years some countries have proposed recommendations to integrate these systems into their urban planning regulations, but these have been general and have not defined specific measures. This paper proposes to achieve this goal by using case studies of three countries with similar characteristics (Spain, Italy and France). A common framework for the integration of SuDS in planning has been proposed that can be exported to other similar places. The urban scales of intervention have been defined (city, neighborhood and street), as well as the actions to be carried out (analysis, planning and regulatory measures) and the urban plans to which they should be applied. This proposal represents an advancement in the application of SuDS as a primary control measure. This breakthrough will significantly improve the resilience of the cities of the future, making them more resilient to the effects of weather and climate change.
