Objective

Maximize run-off of rainwater.

Description

Restriction of pavements and building areas of individual building plots, use of specific pavement materials that are water permeable. The effectiveness of infiltration has to be specifically calculated for each project, depending on soil type, groundwater level, amount of paved areas.

Expected results

Reduced risk of flood, reduced risk of running dry of the surface during drought periods.

Result indicators

Area of water permeable pavements [m²]
