This interactive tool is intended to provide an online atlas to support the Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report and provide map data depicting projections for future hazard exposure and assessing economic and other vulnerabilities due to rising sea levels.
Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report (2017) Hawaiʻi Climate Change Mitigation and Adaptation Commission, Prepared by Tetra Tech, Inc. and the State of Hawaiʻi Department of Land and Natural Resources, Office of Conservation and Coastal Lands, under the State of Hawaiʻi Department of Land and Natural Resources. This report provides the first state-wide assessment of Hawaii’s vulnerability to sea level rise and recommendations to reduce our exposure and sensitivity to sea level rise and increase
our capacity to adapt.
State of Hawaiʻi Statewide Coastal Highway Program Report (2019) Oceana Francis, Ph.D., P.E., Horst Brandes, Ph.D., P.E., Guohui Zhang, Ph.D., David Ma, Ph.D. State of Hawaii Department of Transportation Highways Division An assessment of Hawaii’s roads and highways in vulnerable coastal areas. A central focus is the costs of coastal erosion and road degradation brought on by sea level rise impacts.
County Guidance

West Kauʻai Community Vulnerability Assessment (2020) University of Hawaiʻi Sea Grant College Program. The product of work with local west side communities that sought to identify vulnerabilities and generate ideas for adapting to climate change. Recommendations for the West Kauaʻi Community Plan, a separate, but related process, were also generated.
City Guidance  
Climate Change Brief  (2018) City and County of Honolulu Office of Climate Change, Sustainability, and Resiliency. This brief describes the local, regional, and global impacts of climate change as documented by peer-reviewed scientific literature and credible empirical data sources. It provides a benchmark for the commission, attesting to the Climate Change Commission’s concerns, underpinning the Commission’s decisions and recommendations, and serving to inform those the Commission serves.
Climate Ready O’ahu Web Explorer, City and County of Honolulu Office of Climate Change, Sustainability, and Resiliency. This mapping tool features data from the City, state, and federal governments and represents best available science for a variety of climate change stressors and other regulatory layers on O‘ahu. 
Sea Level Rise and Climate Change: Final White Paper (2018) Primary Urban Center Development Plan, University of Hawai’i Sea Grant College Program. A topical white paper summarizing critical trends, data, and preliminary recommendations for sea level rise and climate change adaptation in urban Honolulu.
Sea Level Rise Guidance (2018) City and County of Honolulu Office of Climate Change, Sustainability, and Resiliency. This report builds on findings in the Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report (2017), Sweet et al. (2017), USGCRP (2017), Sweet et al. (2018), and other scientific literature to provide specific policy and planning guidance on responding to sea level rise by the City.
Shoreline Setback Guidance: ROH Ch. 23 (2019) City and County of Honolulu Office of Climate Change, Sustainability, and Resiliency.
