The escalating impact of climate change has become a significant global concern, particularly in urban environments through the risk of flooding, due to intensified precipitation patterns. Nature Based Solu-tions (NBS), offer effective strategies for mitigating flood risks by enhancing stormwater management and promoting urban resilience. Multicriteria Analysis (MCA) has shown to be useful for identifying suitable areas for NBS, however, there is limited research on its application specifically for urban flood resilience in Sweden. Therefore, this study aims to develop a GIS-based suitability mapping framework within MCA method for allocating suitable areas for two NBS measures: Retention Pond (RP) and Detention Basin (DB), applying it to a case study in Sweden. The study employs a mixed-method approach and consists of (1) framework develop-ment through a literature review, geospatial data assessment, and key-informant interviews, and (2) application of the framework to a case study area in Sweden. In the case study area, the resulting suitability map indicates that 7.5 % of DBs and 7% of RPs met all criteria. Key-informant interviews with local experts provided valuable insights, particularly the exclusion of hazardous zones as well as emphasizing the importance of considering not only biophysical characteristics, but also socio-cultural factors. In conclusion, this study contributes to the body of knowledge on NBS suitability mapping. The findings offer guidance to climate strategists and urban planners on a municipal level, selecting optimal locations for NBS strategies for urban flood resilience and stormwater management.
