FLOODING SCENARIO | Proposal
North eastern Hisingen is not the only area within Gothenburg that is at risk in a future extreme flooding scenario, this is something that the city of Gothenburg is well aware of (Göteborgs stad). The city of Gothenburg is counting a 3,8 m sea-level rise as an extreme situation that could potentially occur around 2100, but is more likely to occur around 2150-2250 (Göteborgs stad). This sea-level rise in combination with heavy rainfall creates a future situation in which current uses on North eastern Hisingen will not be able to function as they do today. This means that changes and adaptations will be necessary to keep the area usable in some way.

Instead of trying to work against the water, the aim was early on set on working with the water. This would mean that the area might not be suitable for the current functions, since they will not function in a flooding scenario. Instead of aiming at preserving the current functions we decided on changing the character of the area and let it flood where it eventually will flood. To do so, a large floodable green area/park is proposed along the river banks. To prevent rain-water run off from flooding current and future residential areas green corridors are proposed along the main water flows. These have the potential of both cleaning and slowing down the water, but also to highlight the qualities of water in your surroundings.
