Objective

To guarantee the hydrogeological and hydraulic safeguard of already built areas or improve the pre-existing conditions.

Description

The construction actions in areas subject to hydraulic risk must include hydraulic compatibility measures that include the disposal of rainwater through the creation of reservoir and lamination systems; construction of adequate rainwater drainage systems for paved areas; construction of sewer and disposal lines; prohibition of covering waterways.

Expected results

Reduced vulnerability of buildings to flood damage not only due to climate change in already critical inhabited areas but also to ordinary events.

Result indicators

Volume of stored or drained water [m³]
Disposal lines [m²]
