As climate change continues to impact coastal regions, the National Oceanic and Atmospheric Administration (NOAA) has developed an invaluable tool to help residents visualize future changes in their city. Their interactive map provides a detailed look at how rising sea levels could reshape Los Angeles’ coastline and beyond.
Given Los Angeles’ broad coastline, monitoring potential future changes is crucial. As sea levels rise, the potential transformation of coastal landscapes poses a significant concern for residents. To assist Angelenos in visualizing these potential impacts, the interactive map developed by NOAA’s allows users to explore how various sea levels could affect L.A. County.
Examining the map reveals projected impacts from Santa Monica to Newport Beach. For instance, even under the most extreme projections of a 10-foot rise in sea levels, much of Los Angeles County would remain above water. However, specific areas like Venice, Marina del Rey, and Playa Vista could experience significant changes by 2100. Venice might see increased flooding, while Marina del Rey and Playa Vista could face elevated risks of high tide flooding and coastal erosion.
Expanding the view beyond L.A. County — parts of central Santa Barbara would also be at risk of flooding, and most areas around the San Francisco Bay could experience substantial sinking.
The interactive tool allows users to zoom in and explore how different sea level scenarios across the U.S. might reshape these areas, with predictions extending to 2100 and potential rises under the most severe conditions. Tools include six tabs to explore: Sea Level Rise, Local Scenarios, Mapping Confidence, Marsh Migration, Vulnerability, and High Tide Flooding.
