PCA - Priority Conservation Areas

There is no question that we all want parks and green spaces, and ABAG and MTC have created an opportunity to address this goal across the Bay Area.

Priority Conservation Areas, or PCAs, are regionally significant open spaces which have broad agreement for long-term protection. These are lands that are being pressured by urban development and other factors, and they are supported through local government consensus.

Over 180 PCAs have been adopted by the ABAG Executive Board. Projects located within these areas are eligible for funding through the One Bay Area Grants, or OBAG, program.

PCAs are categorized by four designations that recognize the vitality of the Bay Area’s natural systems, rural economy and the health of all residents:

  • Natural Landscapes
  • Agricultural Lands
  • Urban Greening
  • Regional Recreation

The next opportunity to nominate new PCAs will occur as part of the next iteration of Plan Bay Area, no later than 2025.

PCA Refresh

In November 2021, MTC and ABAG were awarded a grant from the Sustainable Agricultural Lands and Conservation (SALC) Program managed by the California Department of Conservation to support a refresh of the PCA planning framework. This effort kicked off in June 2022. It will identify recommendations to make the region’s conservation planning framework more data-driven and science-based by late 2023, while also incorporating a wider range of policy concerns, such as equity and resilience to climate hazards.

The project will:

  • Evaluate all aspects of the current PCA nomination, evaluation and designation process;
  • Articulate a vision for next-generation PCAs;
  • Establish clear goals and objectives;
  • Identify the needs of project applicants; and
  • Develop guidelines and resources, with an emphasis on data and mapping.

The effort will culminate in a final report of major findings, including a recommended suite of options for regional policymakers to consider with respect to planning, policy and funding.


Partnership and collaboration will be a key component of the PCA refresh. Planned activities for partner and stakeholder engagement (including with local jurisdictions) will include workshops, surveys, one-on-one and small group focused discussions, among others.
