Tool risk reduction measures

100 RISK REDUCTION MEASURES

Infiltrating pavements/permeable surfaces; unsealing

Permeable paving is designed to allow rainwater to infiltrate through the surface, either into underlying layers (soils and aquifers), or be stored below ground and released at a controlled rate to surface water. Sealed surfaces can be replaced by different materials, such as gravel turf, grass pavers, concrete pavers with drainage or porous concrete. This is suitable for parking lots, cycling paths, walking paths and access roads, terraces and yards.

Fields of action
Forests, Farmland, Buildings, Settlement areas
Additionally to flood risk reduction by storing surface runoff, the measure has medium or high possible benefits for the following biophysical impacts and ecosystem services: Increase infiltration and/or groundwater recharge; Filtration of pollutants; Intercept pollution pathways; Reduce erosion and/or sediment delivery
