Gli spazi pubblici aperti per la rigenerazione urbana nella prospettiva postpandemica. Indicazioni di metodo. La "best practice" del "Parco Europa Unita" in Potenza

The Sars-CoV-2 pandemic has imposed on each of us a long and difficult experience. In this crisis, both elements of criticality and change emerged: elements which had already been underway for some time. The imposition of smart working (in both public and private context) and the physical displacement restrictions (which restrained accessibility to central areas) have promptly led to the demand relocation for public services (nearby green spaces) and private commercial services. The critical issues of a settlement model that has always remained predominantly centripetal have become evident. The instances of widespread urban quality, of better quality of life, of ecosystemic rebalancing of the settlement system have become, for few moment, pressing and shared. In short time, even if not promptly followed by market trends, the level of urban rent value (in its pricing effects in shop and home rents) appeared to be widely excessive. In metropolitan areas, it was made clear that through a diversified planning of timetable and through the diversification of flows, it would be easy to restore existing mobility infrastructures, with only management measures, to excellent service levels. In this new perspective it is interesting, after fifteen years, to deepen the methods and the tools of the experience of urban regeneration, reported by many (Ispra; National Council of Architects) as "best practice", of "Europa Unita" park in Potenza. This project allows to deepen the design strategies implemented to enhance the "role of the ecological-environmental component within urban systems". This is accomplished through a "systemic approach" and with an "holistic vision" rooted in the evolutionary trends of territorial realities. The fifteen years passed since the Park inauguration allows us to go back to the method and project choises with the aims to find confirmations and any critical issues. This can be done by verifying the project at different scales as well as by studying the choices of planning tools that have governed this successful process of urban transformation.
