The area known as ‘delle roccette’ on the Tonale and Mendola Road shortly after Passo Mendola is subject to rockfall, avalanche and debris flow events. To mitigate risks derived from natural hazards, structural and non-structural mitigation measures have been adopted, such as the establishment of an avalanche commission to provide decision-making support to the Road Service. The evaluation of both efficiency and effectiveness of the measures taken, has been validated by the degree of acceptability of residual risk of human life loss before and after mitigation strategies have been applied.
Keywords: rockfall, avalanches, risk management, mitigation measures, acceptable risk, maintenance, avalanche commission.
