About the Project

Hawaiʻi is highly vulnerable to coastal hazards including impacts related to climate change and sea-level rise.  As sea level rise accelerates and climate and ocean conditions change, it is becoming increasingly important for island communities to develop policies and implement strategies that reduce vulnerability and increase resilience to natural hazards.  Development, infrastructure, and populations in Hawaiʻi are generally concentrated on low-lying coastal plains making communities and local economies highly vulnerable to flooding, coastal erosion, sea level rise, and coastal disaster events including tropical cyclones and tsunamis.  The overarching goal is to increase community resilience to coastal hazards and impacts from climate change and sea level rise in Hawaiʻi through three complementary projects building on the Hawai‘i Sea Level Rise Vulnerability and Adaptation Report completed by the State of Hawaiʻi in 2017 (available at climateadaptation.hawaii.gov) and other recent projects and initiatives:

The Hawai‘i Sea Level Rise Viewer

This online Viewer incorporates the best available science on sea level rise predictions for Hawai‘i including exposure to passive flooding, annual high wave flooding, coastal erosion, and a combined sea level rise exposure area. The Viewer also includes vulnerability layers depicting potential economic loss of land and structures and flooded highways.  With high-resolution interactive maps, the Viewer serves as a companion digital atlas for the State Sea Level Rise Vulnerability and Adaptation Report. This tool is accessible to communities and decision-makers across Hawai‘i allowing them to visualize and plan for the local impacts of coastal hazards and sea level rise. The Viewer was developed by the Pacific Islands Ocean Observing System under the direction of Hawaiʻi Sea Grant and the Hawaiʻi Department of Land and Natural Resources. The Viewer was completed in December 2017 along with the State Report and is available at hawaiisealevelriseviewer.org or climateadaptation.hawaii.gov.

Integrating Coastal Hazards and Sea Level Rise Resilience in Community Planning

It can be challenging to translate state-wide policy into action at the local level. This project focuses on developing practical guidelines for incorporating recommendations from the Hawai‘i Sea Level Rise Vulnerability and Adaptation Report and the Hawai‘i Climate Adaptation Priority Guidelines into the community planning process. Ultimately, this project will build capacity in state and county government to address climate change, sea level rise, and coastal hazards through appropriate entry points in the comprehensive community planning process. This project will produce an interim guidance document in April 2019 and a final in April 2020.

Resilience-Focused Disaster Reconstruction Planning

With climate change and rising sea levels, Hawai‘i is expected to experience more severe impacts from coastal disasters such as hurricanes, tsunami, and extreme high wave events. A critical aspect of community resilience is the ability to build back safer, stronger, smarter, and faster after a disaster. This project works with state and county government to promote resilience-focused recovery practices that enable communities to rebuild quickly while also protecting sensitive environmental and cultural resources and increasing preparedness for future disasters. The project will produce a guidance document with model resources, including a model recovery ordinance and model pre-disaster recovery plan framework, to be completed in December 2018.
