Washington Sea Grant partnered with the Jamestown S'Klallam Tribe and Adaptation International to develop a set of local sea level rise projections, and sea level scenario maps for the Jamestown S'Klallam community. The assessments are being used to identify priority adaptation actions, tribal areas or resources that are particularly vulnerable to sea level rise, and have also been integrated into community long-term planning. Additionally, Washington Sea Grant is partnering with North Olympic Peninsula Resource Conservation District and Adaptation International on a multi-sector climate change vulnerability assessment and adaptation plan, including sea level rise and coastal flooding projections for coastal communities in Clallam and Jefferson Counties.

Washington Sea Grant led the development of the Olympic National Marine Sanctuary (OCNMS) Climate Change Assessment, which examined the vulnerability of sanctuary resources to climate change. The report, intended for OCNMS staff, the OCNMS advisory committee, and the Intergovernmental Policy Council, is being used as a springboard for climate change adaptation activities in the sanctuary, and adjacent (mostly tribal) communities.
