Sec. 611.10 Appendix "S ", Coastal Construction
Building Code, established. The State of Florida's
Model Coastal Construction Code is hereby adopted as
Appendix "S ", Coastal Construction Building Code, of
the 1985 edition of the Standard Building Code. For
clarity, the numerals to the right of the decimal in
this chapter shall correspond to the same numerals in
other appendixes to the Standard Building Code. For
example, 611.101 of the City Code shall correspond to §
101, etc.
Sec. 611.100.1 Title. The provisions herein
contained shall constitute the "Coastal Construction
Building Code" for the City of Cape Canaveral, Florida,
and shall be referred to as the "Coastal Code ".
Sec. 611.101.1 Purpose. The purpose of the
Coastal Code is to provide minimum standards for the
design and construction of buildings and structures to
reduce the harmful effects of hurricanes and other
natural disasters occuring along the coastal areas of
the City of Cape Canaveral. These standards are
intended to specifically address design features which
affect the structural stability of the beach, dunes,
and topography of adjacent properties. The Coastal
Code is site specific to the coastal building zone and
coastal barrier islands as defined herein and is not
applicable to other locations. In the event of a
conflict between this chapter and other chapters of
this code, the requirements resulting in more
restrictive design shall apply. No provisions in this
chapter shall be construed to permit any construction
in any area prohibited by local city, county or state
regulation.
Sec. 611.102.1 Applicability. The requirements
of this Coastal Code shall apply to the following types
of construction in the City of Cape Canaveral.
A. The new construction of, or improvement to
major structures, nonhabitable major structures, and
minor structures as defined herein.
B. Construction which would change or alter the
character of the shoreline (e.g., excavation, grading,
paving). The Coastal Code does not apply to minor work
in the nature of normal beach cleaning or debris
removal.
Sec. 611.102.2 Existing Structures. The
requirements of this chapter shall not apply to
existing structures, structures under construction, or
structures for which a valid and unexpired building
permit was issued or applied for prior to the adoption
of the Coastal Code.
Sec. 611.102.3 Multi -Zone Structures. For
structures located partially in the coastal building
zone the requirements of the Coastal Code shall apply
to the entire structure.
Sec. 611.102.4 Construction Seaward of Mean High
Water. Structures or construction extending seaward of
the mean high water line which are regulated by Section
161.041, Florida Statutes, (e.g., groins, jetties,
moles, breakwaters, seawalls, revetments, beach

nourishment, inlet dredging, etc.), are specifically
exempt from the provisions of this chapter. In
addition, the Coastal Code does not apply to piers,
pipelines, or outfalls which are regulated pursuant to
the provisions of Section 161.053, Florida Statutes.
Sec. 611.102.5 Applications for Permits.
Applications for building permits for all construction
in the coastal building zone and on coastal barrier
islands, if not of normal or usual design as determined
by the Building Official, shall be certified by an
architect or professioanl 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.
Sec. 611.103.1 Definitions. The following terms
are defined for general use in the Coastal Code.
Beach means the zone of unconsolidated material
that extends landward from the mean low water line to
the place where there is a 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 ".
Breakaway wall or frangible wall means a
partition independent of supporting structural members
that will withstand design wind forces, but will fail
under hydrostatic, wave, and runup forces associated
with the design 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 property.
Building Support Structure means any structure
which supports 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.
Coastal Barrier Islands means geological 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 were separated from the mainland by artifical
channelization for the purpose of assisting marine
commerce shall not be considered coastal barrier
islands.
Coastal Building Zone means the land area 1500
feet landward of the coastal construction control line
established pursuant to Section 161.053, Florida
Statutes. For those coastal cities and counties for
which no coastal construction control line has been
established, the "coastal building zone" is defined as
that land area 3,000 feet landward from the mean high
water line. On coastal barrier islands, the "coastal
building zone" is defined as the area 5,000 feet
landward from the coastal construction control line or
the entire island, whichever is less. On barrier
ORDINANCE NO. 4 -86

MICROFILMED AUG 87
islands for which no coastal construction control line
has been established, the "coastal building zone" is
the area 5,000 feet landward from the mean high water
line or the entire island, whichever is less.
Column Action means the potential elastic
instability in piles or columns resulting in axial or
lateral bending of the member due to compressive
stress.
Construction means the carrying out of any
building, clearing, 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, "constuction" refers to the
act of constuction or the result of construction.
Dune means a mound or ridge of loose sediments,
usually sand - sized, lying landward of the beach, and
deposited by natural or artificial means.
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.
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 nineteen (19) year period. (See Section
177.27(15), F.S.).
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.
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.

this code. All structures shall be designed so as to
minimize damage to life, property and the natural
environment. Assistance in determining the design
parameters to minimize such damage may be found in the
reference documents listed in Section 611.301.6.
Sec. 611.104.2 Structural Requirements for Major
Structures
A. Foundations All major structures shall be
anchored to their foundations in such a manner as to
prevent flotation, collapse, or lateral displacement.
Foundation design and construction shall consider all
anticipated loads resulting from design storm
conditions, including wave, hydrodynamic, hydrostatic,
and wind loads acting simultaneously with dead loads.
Erosion computations for foundation design shall
account for all vertical and lateral erosion and
scour - producing forces, including localized scour due
to the presence of structural components.
1. Pile Foundations shall be required for
buildings located in Federal Emergency Management
Agency Flood Insurance Rate Map "V" (velocity) zones or
where impacted by wave action.
(a) Pile dimensions, spacing and embedment
shall be designed consistent with the requirements of
the site, taking into account all vertical, lateral,
erosion and scour - producing forces.
(b) Piles shall be driven to a penetration
which achieves adequate bearing capacity taking into
consideration the anticipated loss of soil above the
design grade.
(c) In addition to the normal foundation
analysis, the pile foundation analysis shall consider
piles in column action, where appropriate, from the
bottom of the support structure to the design grade.
(d) Consideration shall also be given to the
degree of exposure to wave attack and the resulting
impact loads on lateral or diagonal bracing between
piles.
2. Monolithic Foundations may be permitted in
Federal Emergency Management Agency Flood Insurance
Rate Map "A" or "B" zones or in locations not impacted
by wave action.
(a) Monolithic foundations may be used if
soil conditions permit and if located at an elevation
which minimizes their effect on the beach and adjacent
properties. Due consideration shall be given to their
vulnerability to erosion under design storm conditions.
(b) In the event that a monolithic foundation
is used, the maximum elevation of the top of the slab
is to be below the design scour depth (see Chapter
5.28, Shore Protection Manual, U.S. Army Corps of
Engineers, 4th edition, 1984) unless positive methods
are provided to prevent scour.
ORDINANCE NO. 4 -86
PAGE 5 OF 10
MICROFILMED AUG 87
(c) Other types of spread footings such as
running footers or pads may be permitted when positive
methods are provided to prevent scour.
B. Understructures. No substantial walls or
partitions shall be constructed beLow the level of the
first finished floor. This does not preclude the
construction of:
1. Stairways
2. Shearwalls essentially perpendicular to
breaking waves
3. Shearwalls essentially parallel to breaking
waves which do not exceed a maximum of twenty (20)
percent of the building length
4. Wind or sand screens constructed of fabric or
wire mesh
5. Light open lattice partitions with individual
wooden lattice strips no greater than three - quarter
(3/4) inch thick or three (3) inches wide
6. Elevator shafts
7. Breakaway or frangible walls; or
8. Substantial walls constructed above the wave
action and storm surge expected under design storm
conditions.
C. Buildings and Floor Elevations. The minimum
elevation for the underside of the building
support structure (excluding foundation) shall be above
the elevation of the design breaking wave crests or
wave uprush superimposed on the storm surge with
dynamic wave setup expected under design storm
conditions. The elevation of the storm surge with
dynamic wave setup shall be either the elevation
established by the Florida Department of Natural
Resources Coastal Construction Control Line Study or
the base flood elevation for the specific area
established by the Federal Emergency Management Agency
as determined by the design engineer.
D. Erosion and Design Grade. The elevation of
the soil surface to be used in the design of
foundations, calculation of pile reactions and bearing
capacities shall not be greater than that which would
result from the erosion reasonably anticipated as a
result of design storm conditions. Calculation of the
design grade shall take into account localized scour
due to the presence of structural components. Erosion
computations for foundation design shall consider all
vertical and lateral erosion and scour - producing
forces.
E. Wave Force Design.
1. Calculations for wave forces resulting from
design storm conditions on building foundations and
superstructures may be based upon the minimum criteria
and methods prescribed in the Naval Facilities
Engineering Command Design Manual, NAVFAC DM -26, U.S.
Department of Navy Shore Protection Manual, U.S.

Department of the Army Corps of Engineers; U.S.
Department of the Army Coastal Engineering Research
Center Technical Papers and Reports; the Technical and
Design Memoranda of the Division of Beaches and Shores,
Florida Department of Natural Resources; or other
professionally recognized methodologies which produce
equivalent design criteria.
2. Breaking, broken, and nonbreaking waves shall
be considered as applicable. Design wave loading
analysis shall consider vertical uplift pressures and
all lateral pressures to include impact as well as
dynamic loading and the harmonic intensification
resulting from repetitive waves.
F. Hydrostatic Loads. Calculations for
hydrostatic loads shall consider the maximum water
pressure resulting from a fully peaked, breaking wave
superimposed upon the design storm surge with dynamic
wave setup. Both free and hydrostatic loads shall be
considered. Hydrostatic loads which are confined shall
be determined using the maximum elevation to which the
confined water would freely rise if unconfined.
Vertical hydrostatic loads shall be considered both
vertically downward and upward on horizontal or
inclined surfaces of major structures (e.g., floors,
slabs, roofs, walls). Lateral hydrostatic loads shall
be considered as forces acting horizontally above and
below grade on vertical or inclined surfaces.
Hydrostatic loads on irregular or curved geometric
surfaces shall be determined by considering the
separate vertial and horizontal components acting
simultaneously under the distribution of the
hydrostatic pressures.
G. Hydrodynamic Loads. Hydrodynamic loads shall
consider the maximum water pressures resulting from he
motion of the water mass associated with the design
storm. Full intensity loading shall be applied on all
structural surfaces above the design grade which would
affect the flow velocities.
H. Design Conditions - General.
1. Foundations for all major structures shall be
designed for the horizontal and vertical pressures
generated by wave forces between the elevation of the
design breaking wave crests or wave uprush superimposed
upon the storm surge and the stable soil elevation of
the site.
2. All major structures, except mobile homes,
shall be designed to withstand one hundred forty (140)
mph windspeeds. Horizontal wind velocity pressures
shall not be less than the values given below:

3. Appropriate shape factors shall be applied for
resistance against overturning and uplift as required
elsewhere in this code. Internal pressures on internal
walls, ceilings and floors resulting from damaged
windows or doors shall also be considered in the design
unless the specified windows and doors have been tested
by an approved testing agency and have been shown to be
capable of withstanding the design pressures required
herein.
4. Mobile homes shall conform to the Federal
Mobile Home Construction and Safety Standards of the
Uniform Standards Code ANSI book A- 119.1, pursuant to
§320.823, Florida Statutes, in addition to the other
requirements contained in this chapter.
Sec. 611.104.3 Structural requirements for
Nonhabitable Major Structures. Nonhabitable major
structures need not meet the specific structural
requirements of Sec.. 611.104.2, except that they shall
be designed to produce the minimum adverse impact on
the beach and dune system and shall comply with the
applicable standards of construction found elsewhere in
this code. All sewage treatment and public water
supply systems shall be flood - proofed to prevent
infiltration of surface water expected under design
storm conditions. Underground utilities, excluding pad
transformers and vaults, shall be flood - proofed to
prevent infiltration of surface water expected under
design storm conditions or shall otherwise be designed
to function when submerged under such storm conditions.
Sec. 611.104.4 Structural Requirements for Minor
Structures. Minor structures need not meet the
specific structural requirements of Sec. 611.104.2,
except that they shall be designed to produce the
minimum adverse impact on the beach and dune system and
shall comply with the applicable standards of
construction found elsewhere in this code.

Construction except for elevated walkways, lifeguard
support stands, piers, beach access ramps, gazebos, and
coastal or shore protection structures, shall be
located a sufficient distance landward of the beach to
permit natural shoreline fluctuations and to preserve
dune stability. Construction, including excavation,
may occur to the extent that the natural storm
buffering and protection capability of the dune is not
dimished.
Sec. 611.104.6 Public Access. Where the public
has established an accessway through private lands to
lands seaward of mean high tide or water line by
prescription, prescriptive easement, or any other legal
means, development or construction shall not interfere
with such right of access unless a comparable
alternative accessway is provided. The developer shall
have the right to improve, consolidate, or relocate
such public accessways so long as they are:
A. Of substantially similar quality and
convenience to the public;
B. Approved by the local government; and
