ABSTRACT
The paper presents a semi-quantitative methodology developed to help Italian local authorities in facing multi-risk aspects in their Land Use Planning practices. The methodology acts as a pre-screening of the risks present on the territory, highlighting the areas more exposed to risk and risk interactions, also taking into account aspects neglected by the sectorial plans. A quick overview of the methodology is provided, together with a significant Italian case study: a small town in Piedmont, for which neither the land use planning related to major risk plants, nor the supra-regional plans for flood preventions were sufficient to obtain a detailed representation of the overall risk. The proposed methodology analyzed the context and evaluated the possible interactions, identifying possible environmental consequences, and then addressed further studies and interventions to the critical situations. A dedicated questionnaire was developed for the plants, to examine in depth the assets more exposed to NaTech risks.
