In recent decades, the increasing frequency and intensity of natural disasters has highlighted the urgent need to enhance urban resilience, placing environmental risk reduction among global priorities. Although the importance of integrating resilience strategies into urban planning is now widely acknowledged, local community engagement remains limited. Investing in resilience means not only strengthening response and adaptive capacities but also promoting well-being, social cohesion, and territorial competitiveness. This paper presents the findings of a case study supporting the revision of the detailed plan for the historic town of the municipality of Pollenza (MC), located in a high seismic risk area in central Italy. The research introduces a dynamic method for assessing urban exposure in public open spaces, based on a quantitative index that integrates morphological, functional, and temporal parameters. This approach enables a comparative evaluation of alternative scenarios of urban regeneration and socio-economic development, highlighting how specific design strategies influence urban risk levels and offering guidance for more resilient and inclusive urban planning.
