This paper uses content analysis of urban planning and guiding documents to research and evaluate relative adaptation approaches by categorising and comparing relevant indicators of progress. The scope of the paper is covering the 33 coastal municipalities that experience particularly exposure to negative consequences of climate change induced sea level rise. The findings indicate that the number of municipalities that address sea level rise has increased notably (∼43%) based on planning documents during the past ten years (2013−2022), which supports international trends of increased attention to urban climate change adaptation. Furthermore, the content analysis qualitatively shows based on a newly developed categorization the large variation in planning documents used by municipalities in terms of purpose and approach. Lastly, a comparison of the municipalities indicates that, while there are notable differences in approach and progress, municipalities with established adaptation plans are similarly structured in terms of ambition and level of detail, and could be considered frontrunners in sea level rise adaptation work. Thus, paper provides - based on a replicable and innovative method - current comparative results about progress in latest practices of planning management, relevant as a potential benchmark and/or blueprint for similar adaptation measures of urban coastal communities worldwide.
