City of Genova

Nature-based solutions that address key climate- and water-related challenges have been implemented in Genova’s Lagaccio district, which is a central and densely populated district characterised by disorganised post-war urbanisation mainly formed by residential multi-story buildings and derelict sites. The Lagaccio district occupies a core area of Genova, connecting the old port, the historic town centre and the 850 hectare Peralto natural park with its historical architectural structures.

The Municipality of Genova has transformed the Gavoglio area in the Lagaccio district into a 10,000 m² urban park. The former military barracks in the area have been demolished and the area has developed into a public, inclusive and sustainable urban park built by almost entirely nature-based solutions. All functions of the park have been designed to be compatible with nature and the project involved the implementation of 12 different nature-based solutions.

The park is intended to create a welcoming and sustainable public area through the implementation of green spaces, such as rows and bunches of trees and lawns. The new green spaces have been connected to the existing nearby green areas, which has created a green corridor in which it is possible to increase biodiversity and decrease urban heat stress, ensuring a well-functioning ecosystem. Further, cultivation areas offering space for urban farming and orchards have been implemented as well as a green wall.

The city has also improved water management and quality on site through innovative collection, depuration and reuse of stormwater runoff to irrigate new trees and other vegetation in the Gavoglio area. An infiltration basin and bioswale have been created to collect, store and clean stormwater before its gradual release into water courses, while permeable surfaces have been deployed to provide aquifer recharge. A rain garden, which allows runoff from nearby urban areas to be absorbed, has been installed as well as an underground water retention basin. Gabions, log crib walls and slope afforestation have been installed in the park to increase slope stability and prevent landslides.
