Implications for the Community and the Territory The approval of the hazard zone plan represents a fundamental step for the safety and planning of Lavizzara's territory. The technical analyses and on-site inspections carried out have made it possible to precisely identify the risk areas and define the necessary interventions to prevent future disasters. ### Comparison with the Previous Situation Before the flood, Vallemaggia did not have a detailed plan of the hazard zones.

These interventions aim to prevent future floods and protect the local community. The authorities have already started designing the final interventions, which will be implemented in the coming months. ### Community Involvement The population of Lavizzara has been involved from the beginning in the process of defining the hazard zone plan. The authorities have presented the results of the technical and historical-geological analyses, involving the community in planning the interventions. This participatory approach is fundamental to ensuring that the measures adopted are effective and accepted by the local population. ## Recommended tools For an updated estimate, use the net salary calculator and the CHF-EUR exchange comparator.
