The Sea Level Rise Policy Guidance document was unanimously adopted for use by the Coastal Commission on Wednesday, August 12, 2015. It provides an overview of the best available science on sea level rise for California and recommended methodology for addressing sea level rise in Coastal Commission planning and regulatory actions. It is intended to serve as a multi-purpose resource for a variety of audiences and includes a high level of detail on many subjects. Since the document is not specific to a particular geographic location or development intensity, readers should view the content as a menu of options to use only if relevant, rather than a checklist of required actions.

Changes in Draft Revisions

August 2015 Adopted Guidance

The adopted Sea Level Rise Policy Guidance includes revisions that resulted from Commission discussions and two public comment periods. The most significant of these revisions include:

  • A discussion of Safeguarding California and recent Executive Orders
  • A new section on using scenario-based analysis to approach sea level rise planning
  • A new section on storms, extreme events, abrupt change, and sea level rise
  • A new section on sea level rise adaptation planning and environmental justice, as well as the unique challenges faced by low-income communities
  • A revised chapter on sea level rise adaptation strategies, including additional strategies
  • An expanded chapter on the legal context of adaptation planning, with additional detail on seawalls in the context of existing and new development
  • New text clarifying the scope of the document and potential applicability to other planning documents
  • New text recognizing the increasing demand for funding for sea level rise adaptation planning
  • Additional Next Steps describing future Commission work

These revisions were coordinated with other California state efforts related to climate change and adaptation, including the 2014 Safeguarding California document produced by the California Natural Resources Agency. The revised Draft reflects the broad concepts and strategies in Safeguarding California - particularly the Coast and Oceans chapter - and complements it by providing information specific to the Coastal Act, including Local Coastal Programs and Coastal Development Permits. A discussion of relevant presidential and gubernatorial Executive Orders has also been incorporated to the document.
