Name: Sea-Level Rise - 7 ft MHHW

Display Field: Event

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Projected sea level rise inundation polygons for MHHW at 7ft sea level rise. Data from the NACCS RI save points were analysed and spatially scaled to develop a series of projected flood inundation surfaces to visualize multiple storm return periods and sea level rise scenarios. Mean projections were used for events with a return period of 10 years or less, while the upper 95% confidence interval (CI) values were applied to events with return periods 25 years and greater to provide an extra measure of protection. These NACCS-derived flood surfaces show projected water levels with the widely used bath tub models.These data are primarily for planning, educational, and awareness purposes only and should not be used for site-specific analysis, navigation, or permitting. • The mapping does not incorporate future changes in coastal geomorphology (coastal erosion) and assumes present conditions (no adjustments for climate change) will persist, which will not be the case. The digital elevation model used to map sea level rise and flooding does not incorporate a detailed hydro-connectivity analysis, or engineering grade hydrologic analysis.
