Description: Regional SLR inundation vulnerability was mapped using a modified bathtub method recommended by NOAA CSC and agreed-to by the Compact. The traditional version of the bathtub method applies a flat, single-value water surface to the variable land surface. However, applying a single-value regional water surface across all of SE Florida was not deemed an appropriate approach by either NOAA or the Compact. Water level readings at NOAA stations along the SE Florida coast reveal considerable regional elevation differences. The modified approach entailed using a modeled, varying water tidal surface that takes into account the observed tidal datum variability in South Florida. Based on the Compact’s SLR projection for the SE FL region, the one foot scenario is predicted to occur between 2040-2070, 2 foot from 2060 – 2115 and 3 foot from 2075-2150.Uncertainty in the tidal surface and the elevation data is presented in two categories: (1) More likely to be inundated defined as 100-75% certainty of a given location having an elevation below sea level at high tide for a given scenario and (2) Possibly inundated defined as 25-74.9% certainty.
