Protection and restoration of a coastal settlement

The coexistence between human settlements and water is one of the most compelling challenges for urban planning. The area is known as Idroscalo (seaplane base used between 1928 and 1938), located on a spit of land between the delta of Tiber river and the Mediterranean coast, south-west from Rome, is a valuable zone for social, economic, environmental and urban interest (Somma, n.d.). The purpose of the study is to analyze the risk derived from the combined action Tiber-Tyrrhenian Sea, which affects directly the informal settlement living in the place, using specific one-dimensional hydraulic models formulated through HEC-RAS. The innovative building types proposed for the area allow social interaction maintaining the characteristics of the spontaneous community, preserving the landscape of the protected area as well as reducing the risk of hydrologic events. The key elements of the project are the economic compatibility related to the typological solution compared to conventional construction industry as well as economic recovery for the shipyard industry in the area, which has been in economic distress for more than a decade.
