Hawaii Map Series of Sea Level Rise Inundation of +1, 2, and 3 feet for the Ocean Hazards Database

Published: 5 September 2019| Version 2 | DOI: 10.17632/xf33cd2sd5.2


This database consists of a series of maps showing estimated inundation by sea-level rise (SLR) of +1, 2, and 3 feet on Hawaiian Islands. Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report. Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and county street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Shoreline datasets are provided by NGS (2017). Future SLR for +1 ft, +2 ft, and +3 ft are shown with respect to mean higher high water (MHHW). Please read ‘Description-Map of Sea Level Rise Inundation for +1, 2,3 ft.docx’ for detailed information.
