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

This database consists of a series of maps showing the estimated inundation of Hawaii shorelines caused by sea-level rise (SLR) of 1, 2, and 3 feet. 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). Details on map datasets and their usage to determine estimates of Hawaii sea-level rise can be found in the 2019 State of Hawaii Statewide Coastal Highways Project Report
