Urban landscape planning for the systemic application of Nature-based Solutions (NbS) differs from conventional urban planning when valuing the conservation of existent biodiversity, together with managing cities’ growth and increasing the provision of Ecosystem Services (ES) for the built environment. In this context, the local government of the city of São Paulo has encouraged the installation of Bioretention cells such as rain gardens, stormwater planters, and bioswales, types of NbS, which promote a range of ES and contribute mostly to the improvement of urban runoff water quality. These minor interventions that crack concrete and create permeable spaces in the city fabric produce remarkable benefits but need technical awareness in order to ensure its long-term performance. To be effective, the urban green infrastructure for rainwater management should create interconnected spaces to incorporate systems of diffuse pollution abatement, in addition to adopting technologies that support macro drainage systems. This article presents an up-to-date framework of the implementation of Bioretention cells in the city of São Paulo highlighting its benefits and bringing a critical view of its current application. It discusses design aspects, such as structural factors and basic calculations for geometric parameters, planning and geographical considerations, monitoring and maintenance, including participative insights for planning these structures. Thus, the paper maps what has been done and what needs to be improved for enabling the effective implementation of Bioretention cells such that these NbS can be acknowledged as mainstream technologies for urban rainwater drainage in São Paulo. ; La planificación del paisaje urbano para la aplicación sistémica de Soluciones Basadas en la Naturaleza (SbN) se diferencia de la planificación urbana convencional en la valoración de la conservación de la biodiversidad existente, junto con la gestión del crecimiento de las ciudades y el aumento de la provisión de Servicios ...
