<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset represents flood inundation values derived from a modified bathtub model. It employs a simplified hydrologic connection approach rather than a full engineering-grade hydrologic network analysis. To improve data clarity, presumed hydrologically unconnected inundation areas smaller than 1/10 acre have been removed to reduce noise in the underlying elevation data. Additionally, areas presumed hydrologically unconnected and larger than 1/10 acre have their expected depth values reset to an unknown placeholder (e.g., 99999) to highlight their unverified status.</SPAN></P><P><SPAN /></P><P><SPAN>The base elevation data are sourced from the most recent county LiDAR collection available at the time of the study, with datum transformations applied from NAVD88 to tidal MHHW using corresponding NOAA tide stations as control points. The methodology is adapted from NOAA’s "Detailed Method for Mapping Sea Level Rise Inundation" (January 2017): NOAA Report.</SPAN></P><P><SPAN>https://coast.noaa.gov/data/digitalcoast/pdf/slr-inundation-methods.pdf</SPAN></P><P><SPAN /></P><P><SPAN>Last Updated: 03/03/2025</SPAN></P></DIV></DIV></DIV> |
