Sea level rise is a challenge that requires regional collaboration – from MTC, the Association of Bay Area Governments (ABAG) and regional partners – to build a resilient Bay Area. These groups are working together to identify projects and funding that can help communities adapt to the effects of sea level rise. 

Sea Level Rise in Plan Bay Area 2050+: The Resilience Project List

Plan Bay Area 2050+ is the Bay Area’s long-range plan for transportation, housing, the environment and the economy. Plan Bay Area 2050+ refined the sea level rise adaptation work from the 2023 Sea Level Rise Adaptation Funding and Investment Framework by:

  • Conducting outreach and updating the Framework cost estimate to identify a nearly $100 billion need for sea level rise adaptation projects.
  • Developing a Resilience Project List, which prioritizes sea level rise investments based on urgency (when sea level rise impacts are expected, also known as inundation timing) and project readiness (whether there is a locally proposed solution or not).

A Living Catalogue of Projects: The Bay Adapt Project and Funding Navigator

The Bay Adapt Project and Funding Navigator (Navigator), released in September 2026, is an online platform that shows sea level rise adaptation projects around the Bay Area, including their costs, benefits, funding need, and related funding opportunities. 

The Navigator was developed by the San Francisco Bay Conservation and Development Commission (BCDC) with support from MTC and ABAG. 

The project builds on previous planning efforts, including the Sea Level Rise Adaptation Funding and Investment Framework (2021-2023) and Plan Bay Area 2050+.

To begin to address the nearly $90 billion sea level rise adaptation funding gap the region faces, the Navigator helps communities, project sponsors, decision makers, and funders understand what adaptation projects are being planned across the region and where funding is needed.

Other Recent Sea Level Rise Planning Initiatives

With each of the following planning initiatives, MTC, ABAG and partners are shaping a cohesive regional response to sea level rise.

Interagency Sea Level Rise Memorandum of Understanding (MOU) (2024)

In July 2024, Bay Area agencies signed a Memorandum of Understanding (MOU) to coordinate funding and investment efforts for sea level rise adaptation. Signers include MTC, ABAG, BCDC, the Bay Area Regional Collaborative (BARC), California State Coastal Conservancy (SCC), and the San Francisco Estuary Partnership (SFEP). The purpose of the MOU is to:

  • Align agencies on a shared approach to funding and implementation.
  • Help streamline planning efforts across agencies.
  • Establish BCDC as the lead in developing the Investment Strategy, with MTC-ABAG as key partners.

Sea Level Rise Adaptation Funding & Investment Framework (2023)

The Sea Level Rise Adaptation Funding and Investment Framework study, co-led by MTC, ABAG and BCDC, was the first to quantify the Bay Area’s sea level rise adaptation needs. The study provided a foundation for future funding initiatives, such as future Plan Bay Area cycles and the Investment Strategy. The final report:

  • Identified a $110 billion need for sea level rise adaptation projects.
  • Forecasted only $5 billion in anticipated funding through 2050.
  • Provided a roadmap for securing additional resources and aligning regional investments.

Additional Recent Initiatives

MTC and ABAG’s initiatives build on work recent past efforts:

Connected Efforts from Our Partners

BCDC’s Regional Shoreline Adaptation Plan (RSAP)

The RSAP provides coordinated, actionable guidelines to help local governments create their subregional shoreline adaptation plans by 2035. 

BCDC’s Shoreline Adaptation Project Mapping Program (SAPMap)

The SAPMap is a dataset of sea level rise adaptation projects across the Bay Area, hosted on EcoAtlas,  and is  a vital tool for tracking and coordinating shoreline resilience efforts. It provides much of the underlying data for the Investment Strategy and Resilience Project List.

The San Francisco Estuary Partnership (SFEP)

SFEP helps restore wetlands and shorelines to reduce flood risk, and support climate adaptation across the Bay Area. SFEP also fosters collaboration, distributes funding and supports monitoring to scale these efforts.
