From gray to green infrastructure: Rethinking the Lecco’s waterfront

he impending urbanization of two-thirds of the global population poses a pressing challenge for cities: the urgent need for sustainability. This encompasses not only meeting climate targets but also addressing the burgeoning demand for green public spaces amidst limited urban land availability, exacerbated by ongoing urban densification. Consequently, streets are emerging as pivotal arenas for fostering sustainable urban living and mobility. One-third of urban land worldwide is currently occupied by streets and parking lots, offering a significant opportunity for repurposing into vibrant public realms. Municipal administrations globally are recognizing the potential of transforming underutilized urban infrastructure into multifunctional public spaces. In this context, the city of Lecco, nestled along Lake Como's eastern shore, serves as a compelling case study. Historically disconnected from its lakefront, Lecco experienced significant urban planning changes with the construction of the Lungopiave street in 1928. This road, intended to connect Lecco to neighboring regions, created a stark divide between the urban center and the lakeshore. Despite subsequent traffic rerouting with the opening of tunnels beneath Mount San Martino, Lecco remained detached from its waterfront and its potential recreational offerings. In response, a design competition in 2019 sought to revitalize the city's relationship with its waterfront. Building upon these initiatives, this thesis aims to propose a design solution that responds to contemporary urban needs by reestablishing the connection between the city and nature.
