San Francisco Bay Sea Level Rise & Flood Strategy

Climate change doesn’t just mean a warming planet. It brings with it rising tides and more extreme weather events that endanger communities globally, and right here in the San Francisco Bay Area.

Read our San Francisco Bay Sea Level Rise & Flood Strategy to learn more about how sea level rise and flooding endanger the Bay Area, and what we can do to prepare our region.

Sea Level Rise and Flooding in the Bay Area

Local governments have been slow to update their plans to address the risks from sea level rise and flooding largely because there is currently no regional strategy or regulatory mandates in place. But climate change is already having a profound impact on our communities, and the risks posed are only increasing. Homes that don’t flood today may experience regular flooding from a variety of sources in the future.

The map below reflects a conservative projection of flooding in the Bay Area with up to 36″ of water inundation by 2050. This flooding will be the result of anticipated sea-level rise and expected storm surges of 12″ and 24″ respectively.

While California has long-standing policies to reduce the impacts of natural disasters like earthquakes and wildfires, flooding due to climate change and sea level rise is still largely left to cities and counties to address. This has led to an inconsistent and inequitable patchwork approach that leaves many communities unprepared. Explore the examples below to learn more about sea level rise and flooding near you.

Region-wide Solutions

Save The Bay is acting now to ensure that Bay Area governments create a climate-resilient regional plan for sea level rise and flooding. Our San Francisco Bay Sea Level Rise & Flood Strategy will guide our advocacy on regional flood resilience planning and help us create a more resilient region. These are the key principles:

  • Prioritize nature-based solutions

    Prioritize nature-based solutions

    such as wetland restoration, horizontal levees, and green stormwater infrastructure.
     

  • Center the voices of front-line communities

    Center the voices of front-line communities

    in flood resilience planning.
     

  • Address risks and plan for the future

    Address risks and plan for the future

    by focusing development in low flood-risk areas, and applying new building standards that reflect the latest flood risk projection.
