The objective of this article is to propose a novel model for evaluating retention solutions in urban areas. This model is designed to serve as a tool to support integrated urban planning in the context of reurbanization and climate change adaptation processes. The model is both diagnostic and decision-support in nature, integrating spatial, environmental, and functional data. It analyzes these data based on a spatial dependency matrix. A comprehensive consideration of both physiographic factors (e.g., geomorphological typology and land ownership) and social and institutional factors (e.g., institutional readiness and stakeholder engagement) was undertaken. The modelling employs methodologies that are characteristic of urban and landscape design, including multi-criteria analysis, case studies, expert assessment, and Geographic Information System (GIS) tools. The assessment of the retention potential was conducted with consideration for the typology of buildings, infiltration capacity, soil permeability, and existing infrastructure. The findings of the present study demonstrate that local spatial and social conditions exert a substantial influence on the efficacy of retention implementation. The model enables the prioritization of actions and the selection of suitable solutions (context-sensitive retention strategies), thus making it a valuable instrument for designers, urban planners, and decision-makers. The proposed approach can be used in urban planning as a practical tool to support decisions on resilient city development and urban water management.
