Measures for flood and hydrogeological risk reduction (Mission 2 – Component 4 - Investment 2.1)

The Italian territory is characterised by a significant degree of hydrogeological instability, which has been exacerbated by the effects of climate change.

This risk has a detrimental impact not only in the quality of life but also in the economic activity of the areas most exposed to this risk.

Italy’s Recovery and Resilience Plan provides this measure divided into two lines of action, with Protezione Civile and “Commissioner of Emergency for the reconstruction in the territories of Emilia Romagna, Tuscany, and Marche” affected by the May 2023 floods (Commissario per la ricostruzione nel territorio della regione Emilia Romagna, Toscana e Marche), as responsible Administration, respectively.

Regarding the first line of action, a broad and comprehensive set of interventions shall be undertaken to restore damaged public structures and infrastructures (type E interventions) and reduce residual risk strictly connected to the event and aimed primarily at protecting public and private safety (type D interventions).

The second line of action shall include interventions identified by the Commissioner of Emergency in particular the provinces of Ascoli Piceno, Bologna, Ferrara, Fermo, Firenze, Forli-Cesena, Modena, Pesaro-Urbino, Ravenna, Reggio-Emilia, Rimini.

The interventions shall concern:

• Interventions to restore waterways and increase protection against floods.

The interventions shall include as far as possible nature-based solutions.

The interventions should also promote, to the extent possible, the adoption of sustainable soil and land management practices for supporting long term-resilience of soils, for stopping soil degradation and for mitigating the impacts of climate change;

• Rehabilitation interventions of the local and provincial road network.

The interventions may include technical works to complementary infrastructures (including bridges) that have suffered damage and need to be repaired;

• Interventions to restore public buildings, including public houses and health centres.

The investment shall not foresee the installation or replacement of gas boilers, or the purchase of vehicles.

The investment is financed by Italy’s Recovery and Resilience plan by EUR 1534.4 million 2.1 whole

As part of the investment, the project is located along the SP 170 del Massello, in the municipality of Massello.

The planned works are distributed on the left orographic side of the basin of the Germanasca Torrent of Massello and insist on the provincial road, along the stretch between km 3+000 ca and km 4+500 ca.

The planned interventions are aimed at mitigating the risk of instability of the slope and improving the safety of vehicle transit and will consist of cleaning and scaling of the potentially unstable rocky plagues and in consolidation of rocky plagues with systems of protection against falling boulders (eg traction nets, bolts and rope bindings).

In addition, as a consolidation of the road body and in view of the reuse of material from the debris, where possible, will proceed to the execution of modest under-walls.
