The map contains separate layers for sea level rise from NOAA's Sea Level Rise Viewer Tool, and layers for other relevant variables produced by the Coastal Resilience Evaluation and Siting Tool (CREST), acquired in Spring 2023. This project was done by Ana Paula Tommasini Canestrelli as part of the Master of Advanced Studies in Marine Biodiversity and Conservation (2023) at Scripps Institution of Oceanography (SIO), under SIO's Human Ecology Lab. Methods: Sea level rise and more frequent and intense storms are drivers of increased coastal flooding, so an analysis of different coastal flooding scenarios based on geographic information system datasets available online was prepared to provide a visual indication of the impacts expected. The dataset contains separate layers for sea level rise from NOAA's Sea Level Rise Viewer Tool, and layers for other relevant variables produced by the Coastal Resilience Evaluation and Siting Tool (CREST), acquired in Spring 2023. ArcGIS Pro was used to overlay the coastal flooding datasets found with the geographical boundaries of the La Fortaleza and San Juan National Historic Site World Heritage Site, according to the most recent boundary modification adopted by UNESCO in 2016 (La Fortaleza and San Juan National Historic Site in Puerto Rico – Maps). This analysis made it possible to quantify the area of the La Fortaleza and San Juan National Historic Site World Heritage Site affected under different scenarios and to identify which locations within the site are most threatened.
