Guidance for Disaster Recovery Preparedness in Hawaii

Through a National Oceanic and Atmospheric Administration (NOAA) Regional Coastal Resilience Grant, the Hawaiʻi Sea Grant College Program together with the State of Hawaiʻi Department of Land and Natural Resources (DLNR), Office of Planning, and Tetra Tech, Inc., developed statewide guidance documents and tools to improve community resilience to coastal hazards and sea level rise. These guidance documents and tools support implementation of the recommendations of the Hawaiʻi Sea Level Rise Vulnerability and Adaptation Report (Hawai'i Climate Mitigation and Adaptation Commission 2017) especially to integrate sea level rise adaptation plans and policies into state, county and community plansand to develop

Oceans of Opportunity for Hawai‘i’s Future

by Cary DeringerHawai‘i, an ocean-bound state, is just beginning to discover the myriad ways the sea can counteract increasing energy demands, dwindling fresh water supplies, and worsening food shortages. To see for yourself, visit Keāhole Point on the west coast of the Big Island just south of the Ellison Onizuka Kona International Airport. There you will discover the Hawai‘i Ocean Science and Technology (HOST) Park administered by the Natural Energy Laboratory of Hawai‘i Authority (NELHA), where about 80 percent of the state’s aquaculture and marine products are generated using ingenious ocean-based technologies. Originally founded in 1974 to provide a support

Cesspools in Paradise

by Helen RaineWe take the humble toilet for granted, rarely stopping to think about where all that waste goes. But in Hawai‘i, the reality for thousands of residents is that the plumbing leads straight to a big hole in the ground. There are approximately 88,000 aging cesspools across the state, and some of that untreated waste is making its way into our streams, oceans, and drinking water, leading to illness for swimmers, paddlers, and surfers, as well as stressing our coral reefs and native fauna. Change is on the horizon, however; some innovative new solutions have reached the testing stage

Xeriscaping Conserving Water One Garden at a Time

by Jackie DudockFrom Denver to Honolulu In 1981, inspired by a passion for water conservation and public education, a special task force of the Denver Water Department, Associated Landscape Contractors of Colorado, and Colorado State University kicked-off what became a national water-efficient landscaping movement. From this partnership, the term “xeriscape” was coined and began to be used to describe techniques that, when implemented cooperatively, significantly reduce landscape and garden water use. Xeriscape: from the Greek “xeros,” meaning dry, and “scape” meaning the pattern of the landscape. By 1982, the nation’s first public xeriscape demonstration garden and education program were in

Renewing Community with Stacy Sproat-Beck

by Lurline Wailana McGregorStacy Sproat-Beck was raised in Kalihiwai, a small village between Kilauea and Hanalei on the North Shore of Kauaʻi. “It was an idyllic childhood of hukilau, farming, roaming the mountains, and swimming in the stream in what is probably one of the most beautiful places in the world,” Sproat-Beck recalls fondly. That may be one of the reasons she lives down the road from where she grew up and works nearby as the executive director of the Waipā Foundation, doing the kind of work she has known all her life.

Rising Oceans, Disappearing Waters

by Josh McDanielThe 29 atolls and five low islands of the Republic of the Marshall Islands are distinctive in both their remoteness in the central-western Pacific and the seeming precariousness of the impossibly tiny slivers of land that make up the island nation. Located about halfway between Hawaiʻi and Australia, the entire combined landmass of the Marshall Islands is about the same size as Washington D.C., or the Hawaiian island of Niʻihau, spread across an expanse of ocean the size of Mexico. About half of the total population of 53,000 lives in the capital city on Majuro Atoll, a ribbon

The Next Long Drought

Underneath, towering fronds of the hāpu‘u fern shelter a forest floor slippery with mud. Moisture-loving plants like moss and ferns cover almost every tree surface, from downed logs to upright trunks and spreading branches. And on the forest floor lies wet leaf litter, with more wet fern, wet moss, and rare plants such as the Honohono Hawai‘i jewel orchid. The ʻŌlaʻa Forest Reserve sits on the

Writing the Book on Reef Fish

by Ilima Loomis Richard Pyle recalls joining John “Jack” Randall on a diving expedition in Palau in 1985. Wanting to impress the legendary ichthyologist by discovering a new species of fish, the 18-year-old Pyle scoured the reef for unusual specimens. “Unfortunately, every time I came up with something I had never seen before, Jack not only knew exactly what it was, but shared with me an engaging anecdote about how it was first discovered — in almost all cases by Jack himself!” he wrote in a letter nominating Randall for the International Society of Reef Studies Darwin Medal, which Randall

Huli ‘ia

Huli ‘ia is an observational process documenting seasonal changes and shifts across entire landscapes, ma uka to ma kai (from the mountains to the ocean). Developed by Na Maka o Papahānaumokuākea, the Huli ‘ia process documents these natural changes over time, identifies dominant cycles of important species or natural occurrences (e.g. flowering, fruiting, presence/absence of flora/fauna, cloud formations, spawning or recruiting of fish species, etc.), and assists in identifying any correlations between species and occurrences. Those correlations help to identify the occurrence of a less visible situation (e.g. fish spawning) when a more obvious one happens (e.g. a flower species

Hawai‘i Sea Level Rise Viewer

Across the Hawaiian Islands vulnerability to coastal hazards is increasing with climate change and sea level rise and as development along our shorelines continues to expand. Access to high-resolution local hazard exposure and vulnerability data and maps is critical for communities to understand and plan for increased coastal flooding and erosion with sea level rise. The Hawai‘i Sea Level Rise Viewer serves as an online interactive atlas accompanying the Hawai‘i Sea Level Rise Vulnerability and Adaptation Report, completed in December 2017. The Report and map data in the Viewer incorporates the best-available science on sea level rise and potential impacts.

Resilience-Focused Disaster Reconstruction Planning

Hawai‘i’s coastal communities are particularly vulnerable to impacts from hurricanes, tsunamis, and other coastal disaster events due to the state’s isolated location in the Pacific and development concentrated along low-lying shores. Impacts from infrequent coastal disaster events will become more severe with climate change and sea level rise. Human impacts to coastal environments that act as natural barriers including beaches and reefs also makes our communities more vulnerable to impacts from storms and high waves. The ability to build back safer, stronger, smarter, and faster after a damaging disaster while considering potential impacts to natural and cultural resources is a

Integrating Coastal Hazards and Sea Level Rise Resilience in Community Planning

Over the past decade, Hawai‘i has progressed in recognizing and addressing coastal hazards and the need for adaptation to sea level rise. However, more work still needs to be done to translate broad-scale guidelines and scientific information into action at the local level. This project focuses on developing practical guidelines for incorporating resilience to coastal hazards and sea level rise into county general plans and community plans. In the context of this project, resilience is a community’s ability to adapt and thrive in the face of increasing coastal hazards, climate change impacts, and sea level rise through proactive planning utilizing

Only go to a public hurricane shelter if you hear on TV and radio that it is officially open. A better option may be to shelter in place if: (i) a house has no risk of flooding, (ii) is outside a hurricane storm surge zone, and (iii) is strong enough for the wind.
