On the basis of the US approach, technical legislation for flood damage coverage through specific insurance programs has been proposed in Italy. It envisages the draft of a study (SAI: Studio per l'Assicurazione contro le Inondazioni), similar to the USA Flood Insurance Study (FIS), gathering technical information such as hydrologic-hydraulic analyses, detailed delimitation of flood-prone areas and flooding risk assessment. The economic evaluation of flood insurance programs encourages the extensive use of this tool, requiring a reduced financial effort and a softer environmental impact compared with structural flood protection measures (Reitano, 1994).
