CROSSING RESEARCHES Crosslands: resilience a in the periurban river spaces of the Mediterranean coast.The case of Val Polcevera.

Since the crisis of the industrial sector and the disposal of many factories, the conversion, reuse, and reactivation of industrial dismissed peri-urban hydric areas have been an important topic for architects and urban planners from the late nineties. Peripheral rivers areas, (as the Val Polcereva territory) now incorporated in the city development, have the chance to reinvent themselves as a new polarity in the grown metropolitan area, focusing not only on the essential re-naturali- zation and natural recovery of the stream system, but also on the urban values of the riverfront, as civic and human infrastructure.
