A document prepared for the Southeast Florida Regional Climate Change Compact Steering Committee. 35 p. Concurrentiv, the National Oceanoeranhic and Atmospheric Administration (NOAA) Coastal Services Center began development of the web -based SLR and Coastal Flooding Impacts Viewer to aid visualization and adaptation planning efforts for various SLR scenarios. Pilot studies initially focused on specific geographic areas along the coasts of Delaware, Mississippi, and Alabama; however, the viewer (now called the Sea Level Rise Viewer) has been regularly updated to include a broad range of coastal areas, includingnay all of Indian River County east of Interstate 95 (1-95). For informational tmmoses. Indian River Countv was included in a similar SLR vulnerabili assessment in 2012 that was coordinated by the Seven50 initiative and the Southeast Florida Regional Partnership, which incorporated methodologies developed by the SFRCCC. The assessment, whose results were presented in the 2013 report "Analysis of the Vulnerability to Sea Level Rise of the Northern SE FL Counties in the Seven50 Planning Region" (Appendix A), evaluated three SLR inundation scenarios (e.g. 1, 2, and 3 feet of inundation) and characterized local geographic areas at potential flood risk due to potential SLR. Baseline land elevation measurements, upon which the one foot, two foot, and three foot inundation levels were mapped, were derived from Light Detection and RangingL(LiDAR) vertical elevation data that were obtained from the NOAA Coastal Services Center. These data were orieinally collected in 2007 for the Florida Department of Emergency Management (FDEM). SLR inundation mans depicted flood risks based on two levels of confidence. 80-100% certainty and 20-79.9% certainty, and were categorized as either "more likely" to be inundated or "possibly" inundated, respectively. The local maps presented in the 2013 Seven50 report, provided a clear visual comparison of the magnitude of flood -related impacts that may be encountered in Indian River County under 1, 2, and 3 -ft SLR inundation scenarios.
