Through the spatial development concept adopted in 2019, the Swiss city of Baden has committed itself to active urban development. With the consensual approval of the residents' council, this process starts with the project Oberstadt+ in the form of a co-creation between science, administration, practice and social actors. In contrast to conventional planning procedures, the project uses a GIS-based four-dimensional approach (space and time) to link quantitative and qualitative indicators on inner development with a longer planning horizon. This new approach is intended to overcome the limitations of two-dimensional short-term planning and involve various stakeholders early and throughout in a participatory process. We use ArcGIS Urban, which is based on ArcGIS Pro and Online, for 3D modelling urban land use and design variations, development scenarios and interactive live presentations in various private meetings and public workshops. Furthermore, we use ArcGIS StoryMaps for presentation and documentation and are now venturing into Experience Builder to increase public engagement. Oberstadt+ is a pilot based on the results of the SNF research project "How to grow". Working a broad range of stakeholders and supported by various ArcGIS products, an evidence-based, resilient vision of the urban future is being developed. The process and the results could serve as a model for the redevelopment of other 10-minute-neighborhoods. We have found that combining GIS data with 4D urban visualizations allows stakeholders to understand complex issues and identify long-term visions and intermediate development steps needed to support transformation of 10-minute-neighborhoods into healthy ones. The project supports the development planning of Baden's adjacent to downtown Oberstadt district. This is to be redesigned into a walkable, dense, urban residential 10-minute-neighborhood. Oberstadt+ can therefore serve as an example on how the urban transition to a resilient society can be accelerate using 4D-Geodesign.
