This dataset is an ArcGIS map package containing the Operational Landscape Units and nature-based shoreline adaptation opportunities described in the San Francisco Bay Shoreline Adaptation Atlas. The map package includes the following layers:

  • Operational Landscape Units, including the following components:
    • Primary
    • Submerged 
    • Contributing watershed
  • Adaptation Measures, including suitability for:
    • Nearshore reefs
    • Submerged aquatic vegetation
    • Mudflat augmentation
    • Beaches
    • Tidal marshes
    • Polder management
    • Ecotone levees [Version 2. See Technical Update (SFEI 2021) for details]
    • Migration space preparation
    • Green stormwater infrastructure
    • Creek-to-baylands reconnection

This GIS dataset is not an adaptation plan. The dataset provides information on the suitability of nature-based measures according to the methods detailed in the San Francisco Bay Shoreline Adaptation Atlas. Additional study, planning, and engineering will be required to refine these opportunities.
