<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset contains the possible extent of the Area at Risk Due to Sea Level Rise of the state of Florida, based on the Florida Statute s. 380.093(3)(d)3.b. Requirements for activities or construction within the coastal building zone. The Area at Risk Due to Sea Level Rise is defined as any location that is projected to be below the threshold for tidal flooding within the next 50 years by adding sea level rise using the highest of the sea level rise projections required by Florida Statute s. 380.093(3)(d)3.b. For purposes of this paragraph, the threshold for tidal flooding is 2 feet above mean higher high water. This area expands upon the Coastal Building Zone of Florida, defined by Florida Statutes s. 161.54 Definitions and s. 161.55. The criteria used to delineate the boundaries is detailed below:</SPAN></P><P><SPAN STYLE="font-weight:bold;">Area at Risk Due to Sea Level Rise:</SPAN></P><OL><LI><P><SPAN>Regional MHHW grids were extracted from NOAA’s VDatum standalone datum conversion package.</SPAN><SPAN /></P></LI><LI><P><SPAN>Regional VDatum MHHW grids (rasters) were mosaiced into a statewide MHHW raster.</SPAN><SPAN /></P></LI><LI><P><SPAN>The VDatum MHHW grid was transormed to use the North American Vertical Datum of 1988 (NAVD88) and units of feet.</SPAN><SPAN /></P></LI><LI><P><SPAN>Two feet were added to the MHHW NAVD88 raster to account for the FDEP threshold for tidal flooding.</SPAN><SPAN /></P></LI><LI><P><SPAN>An additional 1.82’ were added to the MHHW NAVD88 raster to account for sea level rise using 20222 NOAA Intermediate sea level rise projections for the 2070 planning horizon.</SPAN><SPAN /></P></LI><LI><P><SPAN>Create a flood inundation raster by subtracting the elevations on the MHHW raster from topographic elevations.</SPAN></P><UL><LI><P><SPAN>Topographic elevations are provided by the FDEM as part of a 2018 statewide LiDAR project.</SPAN></P></LI></UL></LI><LI><P><SPAN>Convert flood inundation raster to a vector polygon format.</SPAN><SPAN /></P></LI><LI><P><SPAN>Clean flood inundation polygon to remove small, isolated inundation polygons that are not hydraulically connected to a tidal flooding source.</SPAN></P></LI></OL><P><SPAN STYLE="font-weight:bold;">Coastal Building Zone:</SPAN></P><P><SPAN>The Coastal Building Zone of Florida was merged with the final dataset to ensure that all original Coastal Building Zone areas were included in the Area at Risk Due to Sea Level Rise dataset.</SPAN></P><P><SPAN>380.0937 Definitions: </SPAN><A href="https://m.flsenate.gov/Statutes/380.0937" STYLE="text-decoration:underline;"><SPAN>https://m.flsenate.gov/Statutes/380.0937</SPAN></A></P><P><SPAN>For issues with this data please contact Jeohusua Lugo at Jeohusua.Lugo@FloridaDEP.gov</SPAN></P></DIV></DIV></DIV> |
