Sea level rise, driven by climate change, presents a significant threat to the modern Baylands, particularly in low-lying areas around Alameda and Oakland. As sea levels continue to rise, these areas face increased risks of flooding, erosion, and habitat loss.

 

Increased Flooding: Rising sea levels lead to higher tides and storm surges, which can inundate low-lying areas, especially during extreme weather events. In Oakland, this threatens not only natural habitats but also urban infrastructure and communities.

 

Loss of Tidal Marshes: Many of the remaining tidal marshes in the Baylands are at risk of being submerged permanently as sea levels rise, unless they can migrate inland or be artificially raised.

 

Adaptation and Resilience: In response to these challenges, there are ongoing efforts to enhance the resilience of the Baylands through restoration and adaptation strategies. These include creating living shorelines, enhancing sediment deposition to raise marsh elevations, and planning for the migration of habitats inland.

• Tidal Marsh Restoration

  • Description: Restoring and enhancing tidal marshes involves re-establishing native

  • vegetation and hydrology in degraded or former marsh areas. This can help to stabilize

  • the shoreline, reduce erosion, and provide a buffer against storm surges and high tides.

  • Benefits: Tidal marshes can absorb floodwaters, reduce wave energy, and trap sediments, which can help to elevate the marsh surface in response to rising sea levels. They also provide critical habitat for wildlife.

• Living Shorelines

  • Description: Living shorelines use natural elements like plants, sand, and rock to stabilize the coastline. Techniques might include planting native vegetation, installing biodegradable materials, and creating oyster reefs or other structures that mimic natural features.

  • Benefits: Unlike traditional hard structures like seawalls, living shorelines can adapt over time to changing conditions. They help reduce erosion, improve water quality, and provide habitat for marine life.

We will continue to:

• Engage local experts within the OAAC, Scientific Partners, and consultant team

• Use the green-to-gray spectrum, integrating nature-based features and hybrid solutions wherever feasible

• Learn from existing pilot projects, and identify where new pilot projects may be needed in the Subregion
