In the context of rapid urbanization and severity of extreme weather events related to climate change (e.g., heavy rainfall, urban flooding, droughts), stormwater management has become a major concern for urban communities. Best-management practices (BMPs) play a fundamental function in preventing flooding and protecting water quality, thus contributing to the resilience of cities in the face of extreme weather events. The objective of this paper is to identify the main BMPs used in urban environments and to classify them according to the functions they fulfill, in order to provide a structured understanding of their impact and effectiveness. In addition, the study establishes technical and environmental performance criteria that serve as a reference for ensuring regulatory compliance and the long-term sustainability of these infrastructures. Technical performance criteria are defined based on retention and infiltration parameters, while environmental performance criteria rely on pollutant removal efficiencies and compliance with predefined environmental acceptability thresholds. Finally, the paper presents a detailed flowchart of the developed evaluation tool, which describes the calculation steps required to assess the performance of each component, integrates these results into an overall performance framework, and provides direct support for the differentiated planning of maintenance needs. Future research will focus on applying the developed tool to evaluate the performance of urban stormwater BMPs using a real-world case-study city.
