Give more space for riversstrengthening the containment of floods upstream, “setting back” the current embankments and making them resistant to overflowing. To elaborate And implement innovative strategies for the phenomena of slope failure, given the high number of landslides (over 80 thousand), mostly newly activated following the events of last May. Again: temporary safeguard measures for prevent an increase in urban planning burden, excluding new constructions in flooded areas, or at risk of landslides, outside the urbanized perimeter, pending the updating of the Basin Plans. These are, in extreme summary, some of the guidelines contained in the Preliminary special plan, document provided for by the decree to deal with the emergency caused by the flood events of May 2023, converted into law 100/2023. The rule provides for the preparation of five special plans, thematic; this, relating to interventions on situations of hydrogeological instabilityand the drivers of all the others.
The report of Floor was coordinated by the Po River District Basin Authority, in collaboration with the Emilia-Romagna Region, within the working group chaired by the support structure of the Extraordinary Commissioner for Reconstruction and composed, among others, of the hydraulic authorities, University, Upi, Anci, Metropolitan City of Bologna, Ispra, Forestry Carabinieri. The Regional Council of Emilia-Romagna took note, on Monday 22 April, of the Plan adopted by the Commissioner extraordinary for the Reconstruction, as stated in the Coordination Cabin and shared the temporary safeguard measures adopted by the competent District Basin Authority. Today the presentation of the preliminary document to the Legislative Assembly, in the Territory, Environment, Mobility Commission. The Preliminary special plan contains the first intervention strategies they planning addresses. It will be updated and completed in June 2024 when it sees the light Definitive special plan which will also include the list of structural and non-structural works and interventions. Furthermore, the Region will soon launch a path of active community involvement who were affected by the flood, citizens, the productive world and administrations. A path that aims at sharing the information contained in the Special Plans and actively listening to the requests coming from the territories.
The events of May 2023
From 1 to 3 May 2023, the territory of Emilia-Romagna was affected by hydro-meteorological events of exceptional intensity which caused serious critical issues particularly in the provinces of Forlì-Cesena, Ravenna, Bologna, Modena and Reggio Emilia. On 16-17 May, a further extremely intense meteorological event occurred which, in addition to affecting the territories of the indicated Romagna provinces and that of Bologna, also heavily affected the territory of the province of Rimini. These events caused landslides and floods resulting in the isolation of many localities, the evacuation of numerous families from their homes, serious damage to linear infrastructures, agricultural companies, public and private buildings, hydraulic defense works and the network of essential services. The gravity of the events immediately highlighted the need for a paradigm shift: planning, as well as programming And implementation of interventionsfrom urgent ones financed by commissioner ordinances to more complex structural and non-structural ones, will need a phased approach which will have to be based on a progressive update of hydrological, hydraulic, geological and geomorphological knowledge and on the definition and sharing of defense strategies and new territorial planning to be applied in the affected areas. Hence, the need to develop a special Plan.
