In the wake of climate change and rising water levels the city of Dordrecht is looking for alternative ways to prepare for coming threats other than keep raising the current dikes. In an exploration a suggestion is made to use the southern side of the island as a buffer for excess water. This research takes that suggestion a step further and upgrades it towards a room for the river project. In contrast to normal room for the river projects this case is located on a city border where the city even has wishes to expand. Within this research the city dynamics that have implications for the dike in the room for the river plan are identified. A research by design process was aimed at working towards a solution to account for these city dynamics as well as future water safety needs. This resulted in a framework for the placement of a number of mounds. Mounds that are scaled up to be able to accommodate different types of developments as well as be able to have integrated solutions for self reliance and sustainability.
