Description: This dataset shows a summary of the Census Bureau's TIGER/Line (2023) roadways exposed to future flooding from sea level rise (SLR) and current flooding from hurricane storm surge and floodplains.. Roads were analyzed for exposure to future flooding under twenty SLR scenarios (every half-foot of SLR, from 0.5-feet to 10-feet of SLR above mean higher high water). Roads were also analyzed for exposure to flooding from hurricane storm surge zones and FEMA floodplains. Current flood exposure and future SLR flood exposure was then summarized for the entire length of the original road and attributes were added to represent the percentage and feet of flooded roadway per flood scenario. The road segments are sourced from the U.S. Census Bureau's TIGER/Line data (All Lines County-based Shapefiles) this dataset is from December 5th, 2023.Please Note: TIGER Roads segments classified as ramps were not included in the flood analysis. Elevated road segments, such as ramps, are often incorrectly identified as flooded. This is because the inundation models were created using a bare earth model DEM, which represents ground elevations. In cases of elevated roads, the DEM reports the land under the roadway and not the road surface.

Description: This polygon depicts the possible extent of the Coastal Building Zone (CBZ) of the state of Florida, based on the Florida Statutes s. 161.54 Definitions and s. 161.55 Requirements for activities or construction within the coastal building zone. The criteria to define the extent of the zone varies, depending whether there is a Coastal Construction Control Line (CCCL) in the area or not, and whether it is in the mainland or in a coastal barrier island. Coastal barrier islands were defined as geological features surrounded by marine waters fronting the open waters of the Gulf of Mexico or the Atlantic Ocean, not separated from the mainland by artificial channelization. The criteria used to delineate the boundaries is detailed below: Mainland Areas with CCCL – Limits cover from the Mean High Water (MHW) line to a line 1,500 feet landward from the CCCL. The distance was measured perpendicular to every segment of the CCCL, with the CBZ boundary being the line formed by connecting the landward-most point of all measurements taken. Coastal Barrier Islands with CCCL – Limits cover from the MHW line to either a line 5,000 feet landward from the CCCL measured perpendicularly, or the entire island, whichever is less. Smaller islands attached to the main island were considered part of the coastal barrier island when delineating the CBZ area.Mainland Areas without CCCL – Limits cover all the land seaward from the most landward boundary of the velocity zone (V-zone) fronting upon the Gulf of Mexico or the Atlantic Ocean. Coastal Barrier Islands without CCCL – Limits cover from the MHW line to the landward boundary of the island. All land area in the Florida Keys located within Monroe County is included in the CBZ.161.54 Definitions.https://m.flsenate.gov/Statutes/161.54 161.55 Requirements for activities or construction within the coastal building zone.https://m.flsenate.gov/Statutes/161.55 For issues with this data please contact Jeohusua Lugo at Jeohusua.Lugo@FloridaDEP.gov

Description: This polygon shapefile or featureset depicting Surge Zones, was created using a Surge Modeling application created for the Florida Statewide Regional Evacuation Update Study. The data was derived from National Hurricane Center SLOSH model runs on all the NOAA SLOSH basins throughout Florida. The runs create outputs for all different storm simulations from all points of the compass. Each direction has a MEOW (maximum envelope of water) for each category of storm (1-5), and all directions combined result in a MOMs (maximum of maximums) set of data. The MOMs are used in this surge model. The application uses three input parameters or data: elevation (from LIDAR), SLOSH basin results, and contiguous shoreline or sea polygons. The LIDAR data used has been converted to a DEM with 5ft pixel resolution. All processing takes place at the same raster resolution, so the resulting surge polygons (if 5ft) are a spline curve-fitting representation loosely following the outer third of each pixel. The shoreline features are used to process only contiguous surge zones for each category storm, so there are no lower surge "islands" in the interior of the surge output features.This version is clipped against a 2004, 1:12000 shoreline produced by the Florida Wildlife Conservation Commission (http://atoll.floridamarine.org/Data/Metadata/SDE_Current/fl_12k_2004_poly.htm) and contains detailed attributes summarizing population and facility counts within each zone.

Description: 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:Area at Risk Due to Sea Level Rise:Regional MHHW grids were extracted from NOAA’s VDatum standalone datum conversion package.Regional VDatum MHHW grids (rasters) were mosaiced into a statewide MHHW raster.The VDatum MHHW grid was transormed to use the North American Vertical Datum of 1988 (NAVD88) and units of feet.Two feet were added to the MHHW NAVD88 raster to account for the FDEP threshold for tidal flooding.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.Create a flood inundation raster by subtracting the elevations on the MHHW raster from topographic elevations.Topographic elevations are provided by the FDEM as part of a 2018 statewide LiDAR project.Convert flood inundation raster to a vector polygon format.Clean flood inundation polygon to remove small, isolated inundation polygons that are not hydraulically connected to a tidal flooding source.Coastal Building Zone: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.380.0937 Definitions: https://m.flsenate.gov/Statutes/380.0937For issues with this data please contact Jeohusua Lugo at Jeohusua.Lugo@FloridaDEP.gov

Description: This dataset contains the boundaries of Florida's 67 counties. The interior county boundaries are from the US Census Bureau's TIGER data. The coastal boundaries are from the previous version of CNTBND and are used by Florida Department of Transportation's Efficient Transportation Decision Making (ETDM) process for display purposes. GeoPlan maintains 3 county boundary layers: COUNTYSHORE_AREAS, CNTBND, and COUNTY. These 3 layers will all have the same interior boundaries and different coastal boundaries. The interior boundaries come from the MAF/TIGER Database that is updated yearly by the US Census Bureau. The coastal boundaries differ in the following way: 1) COUNTYSHORE_AREAS - FWRI's detailed shoreline layer (updated periodically) 2) CNTBND - moderately generalized shoreline designed for ETDM display, sourced from historic US Census Bureau data 3) COUNTY - highly generalized shoreline designed for ETDM display, sourced from historic US Census Bureau data
