The project of the tram infrastructure and the new connected road network involves both the construction of new public green areas and the redevelopment of existing ones. The types of landscaping vary from the flowerbeds between the tramway and the road network, to roundabouts, to mitigation areas along the embankments, up to the redevelopment and integration of existing green areas, such as Viale F. Rosselli near the city center and the ones located in the Piagge district.
The landscape project includes the planting of new trees of different species and the creation of flower beds, hedges and lawn areas with different compositions depending on the location along the tramway route.
One of the objectives of the project is the improvement of the conditions of the urban environment crossed by the new tram infrastructure, thanks to the many environmental, aesthetic, social and psychological benefits brought about by the presence of greenery. Increasing biodiversity is another main goal of the project, and it is obtained by using a variety of tree, shrub and herbaceous species that will contribute to the improvement of the microclimate and will encourage the development and diffusion of local fauna.
Generally, plant species with ecological characteristics and resistance to the existing highly urbanized conditions improve the quality of the microclimate. This will be particularly effective in larger open spaces and above all in the Piagge district, where a selection of species of local origin are planted with the aim of performing a landscape and ecological mending with the pre-existing environmental network.
The management of rainwater is addressed by the use of solutions included in the broader theme of green infrastructure, and in particular among the Sustainable Urban Drainage Systems or SUDS. The primary objectives of these solutions are the reduction of peak flows in urban areas, water treatment, prevention of groundwater pollution, without at the same time neglecting the aesthetic aspect and thus creating pleasant, rich of biodiversity and possibly recreational spaces.
