Floodable parks can be designed to control flow rates and decrease flow peaksby storing excess floodwater and releasing it slowly once the risk of flooding haspassed. This type of Natural Based Solutions (NBS) can play a particularlyimportant role in mitigating potential impacts caused by surface run-off waterfrom rain, flash-floods or from small and medium sized watercourses. Otherpotential benefits that floodable parks can provide are among others, reducingthe water flow entering the public sewerage system together with deliveringamenity and biodiversity benefits.
IMPLANTATION: Soft/Medium/Hard
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.
AMORTISATION: Short term/Medium term/long term/no amortization
Actions to be implemented related to the floodable park will have a period of investment recovery up to 15 years.
