Alternative Text Description for Coastal Building Zone (CBZ)

TABLE OF CONTENTS

MAP OVERVIEW

This map shows the Coastal Building Zone (CBZ) for the state of Florida, a regulatory boundary that defines areas subject to special construction requirements along the coast. The CBZ represents the possible extent of zones where coastal building regulations apply, as defined by Florida Statutes. The zone's boundaries vary based on whether a Coastal Construction Control Line exists in the area and whether the location is on the mainland or a coastal barrier island. The map displays this regulatory zone as a continuous boundary following Florida's entire coastline along both the Gulf of America and Atlantic Ocean.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida and its coastal areas. Major cities labeled on the map include Pensacola in the northwest panhandle, Tallahassee in the north-central region, Jacksonville on the northeast coast, Palm Coast south of Jacksonville, Orlando in the central interior, Tampa on the west-central coast, Cape Coral on the southwest coast, and Fort Myers on the lower west coast. The map extends from the Georgia-Florida border in the north to the Florida Keys in the south. The western coastline borders the Gulf of America, while the eastern coastline borders the Atlantic Ocean. Notable geographic features labeled include the Coastal Plain in the north, Apalachicola National Forest in the northwest, Everglades National Park in the south, Dry Tortugas National Park west of the Keys, and Great White Heron National Wildlife Refuge in the Keys. The Straits of Florida are labeled in the southernmost waters.

KEY INSIGHTS

The Coastal Building Zone follows the entire perimeter of Florida's coastline as a continuous regulatory boundary. The zone encompasses all coastal barrier islands completely, including the extensive chain of the Florida Keys. Along mainland coastal areas, the CBZ extends inland from the shoreline as a band of variable width. The zone is notably wider in some mainland sections and narrower in others, reflecting the different regulatory criteria applied based on the presence or absence of Coastal Construction Control Lines. All land area in the Florida Keys within Monroe County is included within the CBZ, making the entire island chain subject to coastal building regulations. The zone creates an unbroken regulatory perimeter around Florida's peninsula and panhandle coasts.

VISUAL ELEMENTS

Coastal Building Zone (CBZ)

This layer represents the regulatory boundary defining areas subject to coastal construction requirements under Florida law.

Coastal Building Zone Boundary (bold dashed black line)

Appearance:

The Coastal Building Zone is depicted as a bold dashed black line that traces the entire Florida coastline.

Distribution:

The boundary line appears along Florida's entire Gulf of America coastline from Pensacola through the panhandle and down the west coast to the Keys, and along the entire Atlantic coastline from the Keys north through the east coast to Jacksonville and the Georgia border.

Notable locations:

The boundary completely encompasses all of the Florida Keys and coastal barrier islands. Along the mainland, the boundary extends inland from the shoreline at varying distances. The zone is particularly prominent around the panhandle region near Apalachicola National Forest, around the Tampa Bay area, along the southwest coast near Cape Coral, throughout the Everglades coastal region, and along the entire Atlantic coast.

Spatial patterns:

The CBZ boundary creates a continuous perimeter following the natural coastline, including all bays, inlets, and coastal irregularities. The inland extent varies along the coast, appearing wider in some mainland sections and narrower in others based on regulatory criteria. Coastal barrier islands and the Florida Keys are entirely enclosed within the zone boundary.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map depicts a regulatory zone rather than a physical geographic feature. The Coastal Building Zone is established by Florida law to control construction activities in coastal areas vulnerable to storm damage and erosion. The extent of the zone varies based on specific statutory criteria including the presence of a Coastal Construction Control Line (CCCL), whether the area is mainland or a coastal barrier island, and the distance from the Mean High Water line or V-zone boundaries. The zone serves as a planning and regulatory tool for coastal development management. Areas within the CBZ are subject to specific construction requirements and permitting processes designed to protect coastal resources and ensure structural safety in high-hazard coastal environments.

DATA CONTEXT

Data Source:

This dataset was created by the Florida Department of Environmental Protection based on criteria defined in Florida Statutes Section 161.54 (Definitions) and Section 161.55 (Requirements for activities or construction within the coastal building zone). The delineation incorporates Mean High Water lines, Coastal Construction Control Lines, V-zone boundaries, and identification of coastal barrier islands. For issues with this data, contact Jeohusua Lugo at Jeohusua.Lugo@FloridaDEP.gov. Data source layer name: CBZ_JUN21.

Definition Query:

No definition query or filter criteria was applied to this dataset.

Scale Information:

The map shows a statewide view of Florida appropriate for understanding the overall extent of the Coastal Building Zone across the entire state. This scale is suitable for general planning and policy visualization but not for site-specific regulatory determinations.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The dataset is dated June 2021 (CBZ_JUN21).

Limitations:

This polygon depicts the "possible extent" of the Coastal Building Zone, indicating the boundary represents an approximation based on statutory criteria rather than a surveyed regulatory line. Site-specific determinations of CBZ boundaries should be verified with official regulatory sources. The delineation of coastal barrier islands as geological features surrounded by marine waters and fronting open ocean waters involves interpretation. The criteria for measuring distances perpendicular to Coastal Construction Control Lines and determining island extents may result in generalized boundaries at this mapping scale.

Map Coverage:

The map covers the entire state of Florida and its adjacent coastal waters, extending from the Georgia border in the north to the Dry Tortugas in the south, and from the Gulf of America in the west to the Atlantic Ocean in the east. Portions of southern Georgia and southern Alabama are visible for geographic context.
