Abstract: Most of the existing underground urban stormwater infrastructures in developed cities are to a very large extent based on the modern urban sewer systems created in the second half of the 19th century in Europe. Urban stormwater management has substantially evolved during the last decades, from a separate engineering field providing a clearly delimited technical service to cities to an increasingly sophisticated and complex domain, attempting to integrate numerous objectives, functions and issues, requiring combined and interacting contributions of multiples disciplines and stakeholders (engineering sciences, environmental sciences, architecture, urban planning and design, landscape, social sciences, etc. ) with the ambition to provide more sustainable and liveable cities. However, this evolution is still not sufficiently implemented as standard practice while new social and environmental constraints, and climate change acceleration, require a much faster adaptation. Promoting innovation and evolution is fundamental to really move towards a true multidisciplinary and integrated approach, and to adapt urban stormwater management to the accelerating climate change. A non-exhaustive and non-hierarchical list of eight issues is tentatively proposed for discussion hereafter: 1) breaking silos, 2) revisit financing, 3) gentrification, 4) social inclusiveness and effectiveness, 5) water culture and meaning, 6) integrating nature, 7) accelerating climate change, and 8) promote innovation.
