Updating California’s Sea-Level Rise Guidance 2023

In 2017, OST convened an Ocean Protection Council (OPC) Science Advisory Team Working Group to update California’s sea-level rise projections. The technical findings from the 2017 report were used by OPC as a basis to develop the 2018 Update of the State of California Sea-Level Rise Guidance (2018 policy document), which provided policy direction for state resource agencies to plan for future sea-level rise. In the 2018 policy document, OPC committed to updating this guidance every 5 years to keep pace with advancements in sea-level rise science. With the 2023 deadline approaching, now is the time to update this guidance with new science.

From June 2022 – June 2023, OST will convene an interdisciplinary and multi-institutional Task Force of scientific experts, policymakers, and boundary spanners to update California’s sea-level rise guidance based on recent scientific advancements. Specifically, the Task Force will:

• Synthesize the best available and most recent sea-level rise science to update California’s current statewide sea-level rise and flooding projections; and
• Develop practical and pragmatic guidance and approaches for end users to use and incorporate updated projections in state and local planning efforts.
