    • NCCOS Competitive Research Program (CRP) Assessment: Future surface water predictions with sea level rise and shoreline adaptation in Santa Monica Bay, California (NCEI Accession 0295695)

    Metadata Updated: November 1, 2025

    This dataset contains predictions of surface water depth (m) under 200 cm (2 m or 6.6 ft) of sea level rise and three storm scenarios by 2100. Estimates of associated socioeconomic impacts are also included. These predictions were completed in the area of Santa Monica Bay, California, specifically Venice Beach and Marina Del Rey. The model domain included ten different modeled infrastructure types to better understand the impact of natural and nature-based features (NNBFs) and conventional infrastructure to reduce sea level rise-driven flood hazards.

    Sea level rise scenario: 200 cm (2 m or 6.6 ft) by 2100.

    Storm scenarios: no storm, annual storm event, 20-year storm event, 100-year storm event.

    Modeled infrastructure types: no action (no change from current), targeted dunes, dunes in locations with elevation below 4 m NAVD88, dunes in locations with elevation below 5 m NAVD88, sea wall, sluice gate, sluice gate + targeted dune, sluice gate + dunes in locations with elevation below 4 m NAVD88, sluice gate + dunes in locations with elevation below 5 m NAVD88, sluice gate + sea wall.

    The following physical and socio-economic impacts were calculated for each modeled infrastructure type within each storm scenario: flood area, flood volume, total economic damages, residential economic damages, nonresidential economic damages, total displaced population, displaced child population, displaced senior population, displaced minority population, displaced low-income population, low construction cost estimate, high construction cost estimate, benefit-cost ratio based on low construction cost estimate, benefit-cost ratio based on high construction cost estimate.

    The file naming convention is a combination of sea level rise height (in cm), the storm scenario, and the modeled infrastructure type. For additional details, please see the data files section.
