The project presented aims to make the Naples waterfront a safe and efficient promenade between city and sea, enable to face up to climate risks through the pedestrianisation of a good part of it (without, however, significantly hindering vehicular transit given that a special carriageway is foreseen for any critical issues) and the introduction of a series of innovative solutions for the recovery, treatment and re-use of rainwater, as part of the sustainable management of urban drainage.
