NFWF (National Fish and Wildlife Foundation)

Description: The National Fish and Wildlife Foundation (NFWF) used the following sources to create a comprehensive database of Aquatic and Terrestrial Indices: Nation Oceanographic and Atmospheric Administration (NOAA) Marine Fisheries Services, Audubon, BirdLife International, and NatureServe. NFWF compiled data from these sources to create an index of priority species and their habitats.

A wildlife index of high value represents watersheds where the most priority species and their habitats are present.

The ultimate design wind speed in miles per hour, for the development of wind loads, shall be determined from Figures 1609.3(1), 1609.3(2), 1609.3(3) and 1609.3(4) in the 2020 Florida Building Code. The exact location of wind speed lines shall be established by local ordinance using recognized physical landmarks such as major roads, canals, rivers and lake shores whenever possible.

Annual occurrences of tidal flooding—exceeding local thresholds for minor impacts to infrastructure—have increased 5- to 10-fold since the 1960s in several U.S. coastal cities. The changes in high tide flooding over time are greatest where elevation is lower, local RSL rise is higher, or extreme variability is less.

In a sense, today’s flood will become tomorrow’s high tide, as sea level rise will cause flooding to occur more frequently and last for longer durations of time.

The red layer in the map represents areas currently subject to tidal flooding, often called “recurrent or nuisance flooding.”

The five relative sea level rise (RSL) scenarios shown in this tab are derived from NOAA Technical Report NOS CO-OPS 083 “Global and regional sea level rise scenarios for the United States” using the same methods as the USACE Sea Level Rise Calculator. These new scenarios were developed by the Sea Level Rise and Coastal Flood Hazard Scenarios and Tools Interagency Task Force, jointly convened by the U.S. Global Change Research Program (USGCRP) and the National Ocean Council as input to the USGCRP Sustained Assessment process and 4th National Climate Assessment. These RSL scenarios provide a revision to the (Parris et. al, 2012) global scenarios which were developed as input to the 3rd National Climate Assessment.

These RSL scenarios begin in year 2000 and take into account global mean sea level rise (GMSL), regional changes in ocean circulation, changes in Earth’s gravity field due to ice melt redistribution, and local vertical land motion.

FEMA National Flood Hazard Layer

Note: Performance and speed of data in this layer are directly dependant on FEMA as the data is generated from a map service running on their website.

Description: Effective regulatory flood hazard information is available as Geographic Information Systems (GIS) data in the form of the National Flood Hazard Layer (NFHL). The NFHL provides users with the ability to determine the flood zone, base flood elevation and floodway status for a particular geographic location. It also has National Flood Insurance Program (NFIP) community information, map panel information, cross section and hydraulic structure information, Coastal Barrier Resource System information (if applicable) and base map information, such as road, stream and public land survey data. The NFHL dataset represents the current effective flood risk data for those parts of the country where maps have been modernized. It is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Revision (LOMR). The NFHL is updated as new data reaches its designated effective date and becomes valid for regulatory use under the NFIP.

Use the vertical slider to simulate water level rise, the resulting inundation footprint, and relative depth. Click on icons in the map to view sea level rise simulations at specific locations.

Water levels are relative to local Mean Higher High Water Datum. Areas that are hydrologically connected to the ocean are shown in shades of blue (darker blue = greater depth).

Low-lying areas, displayed in green, are hydrologically "unconnected" areas that may also flood. They are determined solely by how well the elevation data captures the area’s drainage characteristics. The mapping may not accurately capture detailed hydrologic/hydraulic features such as canals, ditches, and stormwater infrastructure. A more detailed analysis, may be required to determine the area’s actual susceptibility to flooding.

Coastal Building Zone

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.
