The floodable park provides a surface which has capacity to absorb the flow peaks. This NBS is deployed with trees adapted to live in temporary flood conditions (Fraxinus spp., Betula spp., Salix spp.,etc.). This arboreal series will be installed to form a new urban ecosystem to improve and preserve the biodiversity.
The degree of intervention in the environment will mainly depend on the volume of earth from the ground to be excavated and then transported to create the depression used as detention basin.
Actions to be implemented related to the floodable park will have a period of investment recovery up to 15 years.
