Coastal Building Zone
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.
