<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Vulnerability was assessed for the main Hawaiian Islands using the outputs of coastal hazard exposure modeling (provided separately). Potential impacts to coastal highways and major roads were assessed in terms of exposure to chronic flooding in the sea level rise exposure area (SLR-XA) for four future sea level rise scenarios: 0.5 foot, 1.1 foot, 2.0 feet and 3.2 feet based on the upper end of the IPCC AR5 RCP8.5 projections. This particular layer depicts floodway highways and major roads using the 3.2-ft (0.9767-m) sea level rise scenario. While the RCP8.5 predicts that this scenario would be reached by the year 2100, questions remain around the exact timing of sea level rise and recent observations and projections suggest a sooner arrival. </SPAN><SPAN><SPAN>Data compiled by the Pacific Islands Ocean Observing System (PacIOOS) for the Hawaii Sea Level Rise Viewer hosted at </SPAN></SPAN><A href="https://pacioos.org/shoreline/slr-hawaii/"><SPAN><SPAN>https://pacioos.org/shoreline/slr-hawaii/</SPAN></SPAN></A><SPAN>.

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Based on the methodology of sea level rise modeling used in the Hawaii Sea Level Rise Vulnerability and Adaptation Report (Report) and the Hawaii Sea Level Rise Viewer (Viewer), having gone through peer review and publication in the Nature Journal Scientific Reports, the results of this study are sufficiently validated to be appropriately used in land management decisions as the best available information as of the date of publication of the Report, December 2017, consistent with the intent of Act 83 SLH 2014 as amended. This Report is intended to provide a state-wide assessment of Hawaii's vulnerability to sea level rise. The location of projected impacts and economic costs from damages are estimates based on a particular sea level rise scenario. The hazard and vulnerability data and maps provided herein are based on observational data and computer-based models as described in the Report and in published research (Anderson et al., 2018). As with all models, it is important to understand the methods, assumptions, limitations, and uncertainties of the methods used. The risks associated with use or non-use of the results are assumed by the user.</SPAN></P></DIV></DIV></DIV> |
