Recent observations and projections suggest that 3 feet or more of sea level rise could occur earlier than 2100 and even as early as year 2060 under more recently published extreme scenarios (Sweet et al. As such, questions remain around the exact timing of that rise due largely to uncertainties around the future behavior of Earth’s cryosphere and global GHG emission trajectories. coastal erosion (see descriptions of individual hazard layers, below).For this reason, the Report recommends that the magnitude and rate of sea level rise be tracked as new projections emerge and the State begin planning for 3.2 feet of sea level rise now. The footprint of these three hazards were combined to define the projected extent of chronic flooding due to sea level rise, called the sea level rise exposure area (SLR-XA).DEMs used in this study are freely available from NOAA and the U. The horizontal and vertical positional accuracies of the DEMs conform to flood hazard mapping standards of the Federal Emergency Management Agency (FEMA 2012).The IPCC AR5 RCP8.5 sea level rise scenario was used in modeling exposure to passive flooding from sea level rise at 0.5, 1.1, 2.0, and 3.2 feet.Coastal hazard exposure map data were developed for the Report and Viewer by the Coastal Geology Group at UH SOEST and adapted for display and vulnerability assessment by Tetra Tech, Inc.

: The assumptions and limitations described for the three chronic flooding hazards apply to the SLR-XA.Not all hazards were modeled for each island due to limited historical information and geospatial data.The SLR-XA for the islands of Hawaiʻi, Molokaʻi, and Lānaʻi is based on modeling passive flooding only.DISCLAIMER: The data and maps in this viewer illustrate the scale, not the exact location, of potential flooding and erosion with sea level rise.The Hawaiʻi Sea Level Rise Viewer should be used only as a screening-level resource to support management decisions to address exposure and vulnerability to coastal hazards with sea level rise.
