CHAPTER 6
BUILDINGS AND BUILDING REGULATIONS
ARTICLE II. BUILDING CODE
Section 6-20. Scope - Applicability
(b) (4) - Applications for Permits
Applications for building permits for all construction in the
coastal building zone;-i-&-net--o-f--ra tan-ems ate-l--eleelgii--ae--cle-
ceaattned--b -Ote- &-nett---0 --lift- may be required by the
Building Official to be certified by an architect or professional
engineer registered in the State of Florida. Such certification
shall state that the design plans and specifications for the
construction are in compliance with the criteria established by
this Coastal Code.
Section 6-21. Definitions
The following terms are defined for general use in the Coastal
Code:
(a) "Beach" means the zone of unconsolidated material that extends
landward from the mean low water line to the place where there
is marked change in material or physiographic form, or to the
line of permanent vegetation, usually the effective limit of
storm waves. "Beach" is alternatively termed "shore".
(b) "Breakaway wall" or "frangible wall" means a partition in-
dependent of supporting structural members that will withstand
design wind forces, but will fail under hydrestat4e
hydrodynamic wave, and runup forces associated with the design
11110 storm surge. Under such conditions, the wall shall fail in a
manner such that it breaks up into components that will
minimize the potential for damage to life or adjacent
411 property. It shall be a characteristic of a breakaway or
frangible wall that it shall have a horizontal design loading
resistance of no less than ten (10) nor more than twenty (20)
pounds per square foot.
(c) "Building Support Structure" means any structure which sup-
ports floor, wall or column loads, and transmits them to the
foundation. The term shall include beams, grade beams, or
joists, and includes the lowest horizontal structural member
exclusive of piles, columns, or footings.
(d) "Coastal Barrier Islands" means geological surface features
which are completely surrounded by marine waters that front
upon the open waters of the Gulf of Mexico, Atlantic Ocean,
Florida Bay, or Strait of Florida, and are composed of quartz
sands, clays, limestone, oolites, rock, coral, coquina,
sediment, or other material, including soil disposal, which
features lie above the line of mean high water. Mainland
areas which are separated from the mainland by artificial
channelization for the purpose of assisting marine commerce
shall not be considered coastal barrier islands.
(e) "Coastal Building Zone" means the land area 1500 feet landward
of the coastal construction control line established pursuant
to section 161.053, Florida Statutes.
(f) "Column Action" means the potential elastic instability in
piles or columns resulting in axial or lateral bending of the
member due to compressive stress.
(g) "Construction" means the carrying out of any building, clear-
ing, filling, or excavation or the making of any material
change in the size or use of any structure or the appearance
of any land. When appropriate to the context, "construction"
refers to the act of construction or the result of con-
struction.
(h) "Dune" means a mound or ridge of loose sediments, usually
sand-sized, lying landward of the beach, and deposited by
natural or artificial means.
(i) "Major Structure" includes but is not limited to residential
buildings including mobile homes, commercial, institutional,
industrial, and other construction having the potential for
substantial impact on coastal zones.
(j) "Mean High Water Line" means the intersection of the tidal
plane of mean high water with the shore. Mean high water is
the average height of high waters over a 19-year period (See
Section 177.27(15) , Florida Statutes) .
(k) "Minor Structure" includes but is not limited to
pile-supported, elevated dune and beach walkover structures;
beach access ramps and walkways; stairways; pile-supported
elevated viewing platforms, gazebos, and boardwalks; lifeguard
support stands; public and private bathhouses; sidewalks,
driveways, parking areas, shuffleboard courts, tennis courts,
handball courts, racquetball courts, and other uncovered paved
areas; earth retaining walls; sand fences, privacy fences,
ornamental walls, ornamental garden structures, aviaries, and
other ornamental construction. It shall be a characteristic
of minor structures that they are considered to be expendable
under design wind, wave, and storm forces.
(1) "Nonhabitable Major Structure" includes but is not limited to
swimming pools; parking garages; pipelines; piers; canals,
lakes, ditches, drainage structures, and other water retention
structures; water and sewage treatment plants; electrical
power plants, transmission and distribution lines, transformer
pads, vaults, and substations; roads, bridges, streets, and
highways; underground storage tanks; communications buildings
and towers; flagpoles and signs over fifteen (15) feet in
height.
(m) "NGVD" means National Geodetic Vertical Datum - a geodetic
datum established by the National Ocean Service and frequently
referred to as the 1929 Mean Sea Level Datum.
(n) "One Hundred Year Storm" means a shore incident hurricane or
any other storm with accompanying wind, wave, and storm surge
intensity having a one percent chance of being equaled or
exceeded in any given year, during any one-hundred (100) year
interval.
(o) "Seasonal High-water Line" means the line found by the inter-
section of the rising shore and the elevation of one hundred
fifty (150) percent of the local mean tidal range above mean
high water.
(p) "State Minimum Building Code" means the building code adopted
by a municipality or county pursuant to the requirements of
Section 553.73.
(q) "Substantial Improvement" means any repairs, reconstruction,
or improvement of a structure, the cost of which equals or
exceeds a cumulative total of fifty (50) percent of the market
value of the structure either:
(i) Before the repair or improvement started;
(ii) If the structure has been damaged and is being restored,
before the damage occurred.
For the purpose of this definition, "substantial improvement"
is considered to occur when the first alteration of any wall,
• ceiling, floor, or other structural part of the building com-
mences, whether or not that alteration affects the external
dimensions of the structure. The term does not, however,
11/111 include either any project for improvement of a structure to
comply with existing state or local health, sanitary, or
safety code specifications which are solely necessary to
assure safe living conditions; or any alteration of a
structure listed on the National Register of Historic Places
or the State Inventory of Historic Places.
(r) "Coastal Construction Control Line" means the landward extent
of that portion of the beach-dune system which is subject to
severe fluctuation based upon a one hundred (100) year storm
surge, strong waves, or other predictable weather conditions
as established by the Department of Natural Resources in
accordance with section 161.053, Florida Statutes.
Section 2. This Ordinance shall become effective January 1 ,
1987.
