Abstract

Deteriorated urban textures , particularly in central city cores, face complex and intertwined challenges across physical, social, economic, and environmental dimensions—challenges that conventional and fragmented interventions have failed to resolve. This study aims to analyze physical intervention scenarios and document the developmental trajectory of Modarres Street in Kermanshah. It examines the current conditions, evaluates implemented plans, and critiques non-participatory approaches lacking foresight. The research methodology combines documentary analysis, field observation, and social surveying using a validated and reliable questionnaire (Cronbach’s alpha = 0.81). Findings reveal that an exclusive focus on street widening and physical restructuring—without regard for social structure, historical identity, or resident participation—has led to spatial fragmentation and diminished social attachment. Moreover, land-use changes that ignore the cultural and economic capacities of the area have favored speculative interests at the expense of heritage values. In contrast, the presence of centralized management, latent physical potentials, and proximity to the traditional bazaar offer opportunities for participatory regeneration and sustainable development. Ultimately, the study emphasizes the necessity of integrating scenario writing, land readjustment, and participatory planning into future-oriented interventions to restore identity, enhance urban livability, and promote social sustainability in deteriorated urban contexts.
