The project "MURIEL - Multifunctional Urban Retention Spaces: From Idea to Realization", funded by the German Federal Environmental Foundation, was successfully completed in June 2017. The German Federal Environmental Foundation in Osnabrück commissioned DAHLEM as part of a joint venture with the research project, which aims to show ways in which existing inner-city open spaces can be used as emergency flooding areas during heavy rainfall events. The use of public open spaces as temporary retention areas is an important and necessary contribution to municipal flooding prevention - especially with regard to climate change. The three-part documentation summarizing how such retention rooms can be implemented and what needs to be considered in the concept and design is available for download here.
Many municipalities have experienced how massive the damage caused by heavy rain can be in recent years. Targeted flood prevention against are heavy rainfall and flash floods is becoming increasingly important in this context. It represents a major challenge for the municipalities and is closely linked to the municipal adaptation to climate change. The establishment and implementation of coordinated rain risk management is on the one hand a new task. On the other hand, a flood preparedness system coordinated by the various specialist departments increases the complexity of planning and administrative processes and raises questions that are still unanswered. The project "Municipal Flood Prevention - Planners in Dialogue" of the German Institute for Urbanism (DIfU) in cooperation with DAHLEM and numerous experts from the various administrative departments of 15 German cities examined how flood prevention can be achieved within a network of municipalities. The project was funded by the German Federal Environmental Foundation (DBU) in the course of two years. The special feature of the project lies in the fact that the municipalities were represented in each case by the affected department (urban planning, environment, landscaping, roads, municipal water supply and sewerage, disaster control). In eight daily workshops, case studies were developed, where typical obstacles and problems but also possible solutions and success factors lie. Based on the practical experience of the municipalities, recommendations and solutions for administrative work within a municipality were summarized in a brochure. It serves as an aid to municipalities that want to get more involved in heavy rain protection and answers questions (FAQ) on the topics of organization, law, financing, planning/implementation and operation maintenance.
