Updating the State of California Sea-Level Rise Guidance Document

NEW: Catalyzed by direction from Governor Brown in 2016, the update to the State of California Sea-Level Rise Guidance (Guidance) reflects advances in sea-level rise science and addresses the needs of state agencies and local governments as they incorporate sea-level rise into their planning, permitting, and investment decisions.

Download and review the draft here.

The updated Guidance provides: 1) a synthesis of the best available science on sea-level rise projections and rates for California; 2) a stepwise approach for state agencies and local governments to evaluate those projections and related hazard information in decision-making; and 3) preferred coastal adaptation approaches.

The update to the Guidance was developed by the California Ocean Protection Council (OPC), in coordination with the California Natural Resources Agency, the Governor’s Office of Planning and Research, and the California Energy Commission.   This policy document relies on the scientific findings from a recently released report from the OPC’s Science Advisory Team entitled “Rising Seas in California: An Update on Sea-Level Rise,” which synthesized the current state of sea-level rise science, including advances in modeling and improved understanding of the processes that could drive extreme global sea-level rise as a result of ice loss from the Greenland and Antarctic ice sheets.

To ensure that the Guidance was understandable and useful for local and state decision-making, the update process included extensive public outreach, with interviews, listening sessions and public workshops.  Close to 400 coastal stakeholders from city, county, and regional government entities, consulting groups, non-profits, state and federal agencies and tribal representatives provided input that helped shape the framework for the Guidance update and associated web resources (which will be available on the State’s Adaptation Clearinghouse and OPC’s website in early 2018).

The public comment period on the draft Guidance is open from November 15, 2017 through December 15, 2017. All comments should be submitted by email to: COPCpublic@resources.ca.gov.  Questions can be directed to Ocean Protection Council’s Deputy Director, Jenn Eckerle at: jenn.eckerle@resources.ca.gov.

Final adoption of the Guidance is anticipated at the Ocean Protection Council’s January 31, 2018 meeting.

A need to update statewide policy

The State of California Sea-Level Rise Guidance Document, initially released in 2010 and updated in 2013, provides guidance to state agencies for incorporating sea-level rise projections into planning, permitting, investment and other decisions.

Now, the California Ocean Protection Council and the California Natural Resources Agency, in collaboration with the Governor’s Office of Planning and Research, California Energy Commission, and the California Ocean Science Trust, are updating this statewide guidance to reflect recent advances in ice loss science and projections of sea-level rise. The updated guidance will focus on the needs of state agencies and local governments. It will help cities and counties as they comply with a new law that requires them to incorporate climate change into their planning efforts.  The updated guidance document will also assist state agencies prepare for, and adapt to climate change, as directed by Governor Brown’s recent Executive Order.

Updating the science

NOW AVAILABLE: Rising Seas in California: An Update on Sea-Level Rise Science

The California Ocean Protection Council is partnering with the California Ocean Science Trust, which has been charged with leading the scientific component of the update and convening an OPC Science Advisory Team Working Group. The Working Group will compile and review the latest climate research, including considering the implications of recent scientific advances on ice loss dynamics for updating sea-level rise projections. The Working Group includes subject-matter experts in coastal processes, risk assessment, climatic change, ice loss and ice sheet behavior, and statistical modeling. The Working Group will integrate the latest findings from the peer-reviewed scientific literature into a science report that will inform the guidance document update. This science report will be presented to the California Ocean Protection Council at its April 2017 meeting.

The Working Group members are:

  • Gary Griggs, University of California Santa Cruz, OPC-SAT (Working Group Chair)
  • Dan Cayan, Scripps Institution of Oceanography, OPC-SAT
  • Bob Kopp, Rutgers University
  • Claudia Tebaldi, National Center for Atmospheric Research
  • Helen Fricker, Scripps Institution of Oceanography
  • Joe Arvai, University of Michigan
  • Rob DeConto, University of Massachusetts.

Developing science-based, user-informed policy guidance

NOW AVAILABLE: Sea-Level Rise Public Workshop Agenda

Input from users of the guidance document will be solicited at multiple points throughout the update process.  In February, March and April 2017, an Engagement Team led by Susanne Moser Research & Consulting and Climate Access, a not-for-profit organization, will conduct interviews and five listening sessions to better understand the needs of those who will use the guidance document. This input will help ensure that the updated guidance is understandable and useful for planning and decision-making.

In summer 2017, the California Ocean Protection Council and California Ocean Science Trust, with support from the Engagement Team, will convene a series of public workshops with state, regional, and local stakeholders to share the science findings and to solicit feedback on how stakeholders will utilize the guidance document. Public input on the guidance framework will help shape the updated draft policy guidance document. The Policy Advisory Committee, comprised of the California Ocean Protection Council and California Natural Resources Agency, the Governor’s Office of Planning and Research and the California Energy Commission, will prepare the updated draft guidance. This draft will then be circulated for formal public comment in the fall of 2017, with final adoption by the California Ocean Protection Council scheduled for January 2018.

Update to the State of California’s Sea-Level Rise Guidance Listening Sessions:
To ensure that the updated policy guidance is responsive to user needs, accessible, and presented in a way that serves specific decision and planning processes, the Ocean Science Trust, with support from Ocean Protection Council, has commissioned Dr. Susanne Moser and Climate Access to elicit input from planners and managers of coastal communities and assets. After an initial round of 25 one-on-one interviews to better understand these planning processes, 5 listening sessions were conducted to learn more from a wider set of stakeholders.

Each listening session was oriented toward a particular set of planners and managers. Attendees were asked to choose the one that best represents their area of work or expertise. We focused on support for planning and decision-making processes, governmental coordination, dealing with uncertainty and trade-offs, and engagement needs.
