CHAPTER 612
COASTAL CONSTRUCTION CODE
Sec. 612. 01 Title. The provisions contained herein
shall constitute the "Coastal Construction Code" for
construction within the City of Cape Canaveral ,
Florida.
Sec. 612 . 03 Purpose. The purpose of the Coastal
Construction Code is to provide minimum standards for
the design and construction of buildings and structures
to reduce the harmful effects of hurricanes and other
severe storms occurring along the coastal area of the
City of Cape Canaveral, which fronts the Atlantic Ocean.
These standards are intended to specifically address
design features which affect the structural stability
of the beach, dunes, and topography of adjacent proper-
ties. The Coastal Construction Code is site specific
to the coastal building zone 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 restric-
tive design shall apply. No provisions in this chapter
shall be construed to permit any construction in any
area prohibited by city, county, state or federal
regulation.
Sec. 612 .05 Applicability. The requirements of
this Coastal Construction Code shall apply to the fol-
lowing types of construction in the coastal building
zone and on coastal barrier islands in the City of Cape
Canaveral . [No]
A. The new construction of , or substantial improve-
ment to major structures, nonhabitable major
structures, and minor structures as defined herein.
ORDINANCE NO. 7-90

B. Construction which would change or otherwise
have the potential for substantial impact on coastal
zones ( i .e . excavation, grading, paving) .
C. Construction located partially within the
coastal building zone.
D. Reconstruction, redevelopment or repair of a
damaged structure from any cause which meets the defin-
ition of substantial improvement as defined herein.
Sec. 612. 07 Exceptions. The requirements of this
chapter shall not apply to the following:

building permit was issued prior to the effective date
of this code.
D. Construction extending seaward of the seasonal
high-water line which is regulated by the provisions of
Section 161 . 041 , Florida Statutes ( i .e . groins ,
jetties, moles, breakwaters, seawalls, piers, revet-
ments, beach nourishment, inlet dredging, etc . ) .
E. Construction of non-habitable major structures
as defined herein, except for the requirements of
Section 612 . 19 .
F. Construction of minor structures as defined here-
in, except for the requirements of Section 612 .21 .
G. Structures listed in the National Register of
Historic Places or the State Inventory of Historic
Places.
H . Construction for improvement of a major struc-
ture to comply with existing state or local health,
sanitary, or safety code specifications which are
solely necessary to assure safe living conditions.
Sec. 612 .09 Application for Permits. Applications
for building permits for construction in the coastal
building zone, if not of normal or usual design, may be
required by the Building Official to be certified by an
architect or professional engineer registered in the
State of Florida. Such certifications shall state that
the design plans and specifications for the construc-
tion are in compliance with the criteria established by
this Chapter.
Sec. 612 . 11 Definitions. The following terms are
defined for general use in the Coastal Construction
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 vege-
tation, usually the effective limit of storm waves .
"Beach" is alternatively termed "shore" .
ORDINANCE NO. 7-90
PAGE 3 OF 10
Breakaway Wall or Frangible Wall means a partition
independent of supporting structural members that will
withstand design wind forces, but which will fail under
hydrodynamic, 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 which minimize the potential for damage to
life or adjacent property. It shall be a character-
istic of a breakaway or frangible wall that it shall
have a horizontal design loading resistance of no less
than 10 nor more than 20 pounds per square foot.
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 horizon-
tal structural member exclusive of piles, columns, or
footings.
Coastal Barrier Islands means geological surface
features above mean high water which are completely
surrounded by marine waters , that front upon the open
waters of the Gulf of Mexico, Atlantic Ocean, Florida
Bay, or Straits of Florida and are composed of quartz
sands, clays, limestone, oolites, rock, coral, coquina,
sediment, or other material, including soil disposal .
Mainland areas which were separated from the mainland
by artificial channelization for the purpose of assist-
ing marine commerce shall not be considered coastal
barrier islands.
Coastal Building Zone means :
a. For mainland areas which front directly upon
the open waters of either the Gulf of Mexico,
Atlantic Ocean, Florida Bay, or Straits of Florida,
the land area between the seasonal highwater line
and a line 1500 feet landward from the coastal con-
struction control line.
b. For mainland areas where a coastal construc-
tion control line has not been established, the
coastal building zone shall be the land area seaward
of the most landward velocity zone (V-zone) boundary
line established by the Federal Emergency Management
Agency and shown on the Flood Insurance Rate Maps.
c. For coastal barrier islands , the land area
between the seasonal high-water line and a line 5000
feet landward from the coastal construction control
line or the entire island, whichever is less.
d. For coastal barrier islands on which no
coastal construction control line has been estab-
lished, the land area seaward of the most landward
velocity zone (V-zone) boundary line established by
the Federal Emergency Management Agency and shown on
the Flood Insurance Rate Maps .
Coastal Construction Control Line means the landward
extent of that portion of the beach-dune system which
is subject to severe fluctuations based upon a 100-year
storm surge, storm waves, or other predictable weather

Construction means the building of or substantial
improvement to any structure or the clearing, filling
or excavation of any land. It shall also mean any alte-
rations in the size or use of any existing structure or
the appearance of any land. When appropriate to the
context, "construction" refers to the act of construc-
tion or the result of construction.
Dune means a mound or ridge of loose sediments, usu-
ally sand-sized, deposited by natural or artificial
means, which lies landward of the beach.
Major Structure includes but is not limited to resi-
dential 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.
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

detic datum established by the National Ocean Service
and frequently referred to as the 1929 Mean Sea Level
Datum.
One Hundred Year Storm, or 100-Year Storm means a
shore incident hurricane or any other storm with accom-
panying wind, wave, and storm surge intensity having a
one percent chance of being equalled or exceeded in any
given year, during any 100-year interval .

the intersection of the rising shore and the elevation
of 150 percent of the local mean tidal range above mean
high water .
ORDINANCE NO. 7-90
PAGE 5 OF 10
State Minimum Building Code means the Standard Build-
ing Code referred to in Section 611 . 01 of this Chapter .
Substantial Improvement means any repair , recon-
struction, or improvement of a structure, the cost
of which equals or exceeds a cumulative total of 50
percent of the market value of the structure, either
(a) before the repair or improvement is started, or (b)
if the structure has been damaged and is being
restored, before the damage occurred.
For the purposes of this definition, "substantial
improvement" is considered to occur when the first
alteration of any wall, ceiling, floor , or other struc-
tural part of the building commences, whether or not
that alteration affects the external dimensions of the
structure . The term does not, however, 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 alterations of
a structure listed on the National Register of Historic
Places or the State Inventory of Historic Places.
Sec. 612 . 13 Coastal Construction Requirements.
Construction within the coastal building zone shall
meet the requirements of this Chapter. 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 dam-
age may be found in the reference documents listed in
Section 612 . 27 .
Sec. 612 . 15 Structural Requirements for Major Struc-
tures.
A. Design and Construction. Major Structures ,
except for mobile homes, shall be designed and
constructed in accordance with Section 1205 of the Stan-
dard Building Code using a fastest-mile wind velocity
of 110 miles per hour . Major structures, except mobile
homes , shall also comply with the applicable standards
for construction found elsewhere in this code.
B. Mobile Homes . Mobile homes shall conform to the
Federal Mobile Home Construction and Safety Standards
or the Uniform Standards Code ANSI A119 . 1 , pursuant to
Section 320 . 823, Florida Statutes, as well as the
requirements of Paragraph C. , below.
C . Elevation, Floodproofing , and Siting . All major
structures shall be designed, constructed and located
in compliance with the National Flood insurance Regu-
lations as found in 44 CFR. Parts 59 and 60, or Chapter
624 , Flood Damage Prevention, whichever is more restric-
tive.
Sec. 612. 17 Design Conditions.
A. Velocity Pressure . Major structures, except
mobile homes, shall be designed in accordance with the
requirements of Section 1205 of the Standard Building
Code using a minimum fastest-mile wind velocity of 110
or 115 mph as appropriate. These minimum design
pressures are as follows:

B. Foundations . 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 con-
ditions. Foundation design and construction of a major
structure shall consider all anticipated loads acting
simultaneously with live and dead loads. Erosion compu-
tations 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 . Foundation design and con-
struction shall provide for adequate bearing capacity
taking into consideration the type of soil present and
the anticipated loss of soil above the design grade as
a result of localized scour. Erosion computations are
not required landward of coastal construction control
lines established or updated since June 30, 1980 . Upon
request, the Department of Natural Resources may pro-
vide information as to those areas within coastal
building zones where erosion and scour of a 100-year
storm event is applicable.
C . Wave Forces. Calculations for wave forces
resulting from design storm conditions on building foun-
dations 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 pro-
fessionally recognized methodologies which produce
equivalent design criteria. Breaking, broken, and
ORDINANCE NO. 7-90
PAGE 7 OF 10
nonbreaking waves shall be considered as applicable.
Design wave loading analysis shall consider vertical
uplift pressures and all laterial pressures to include
impact as well as dynamic loading and the harmonic in-
tensification resulting from repetitive waves.
D. Hydrostatic Loads. Calculations for hydrostatic
loads shall consider the maximum water pressure result-
ing 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 deter-
mined using the maximum elevation to which the confined
water would freely rise if unconfined. Vertical hydro-
static loads shall be considered both upward and
downward on horizontal or inclined surfaces of major
structures ( i .e . , 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 vertical and horizontal compon-
ents acting simultaneously under the distribution of
the hydrostatic pressures.
E . Hydrodynamic Loads . Hydrodynamic loads shall
consider the maximum water pressures resulting from the
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.
Sec. 612 . 19 Structural Requirements for Nonhabit-
able 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 stan-
dards of construction found in the Standard Building
Code. All sewage treatment and public water supply
systems shall be flood-proofed to prevent infiltration
of surface water anticipated under design storm
conditions. Underground utilities , excluding pad trans-
formers 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. 612. 21 Structural Requirements for Minor Struc-
tures. Minor structures need not meet the specific
structural requirements of Sec. 612 . 15 , 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 in
the Standard Building Code.
Sec. 612 . 23 Location of Construction. Construc-
tion, except for elevated walkways , lifeguard support
stands , piers , beach access ramps, gazebos, and coastal
or shore protection structures, shall be located a suf-
ficient 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
diminished.

Sec. 612 . 25 Public Access. Where the public has
established an accessway through private lands to lands
seaward to mean high tide or water line by prescrip-
tion, 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 approved by
the Department of Natural Resources whenever improve-
ments are involved seaward of the coastal construction
control line; and
C. Consistent with the coastal management element
of the local comprehensive plan adopted pursuant to
Section 163 . 3178, Florida Statutes.
Sec. 612 . 27 References . Assistance in determining
the design parameters and methodologies necessary to
comply with the requirements of this chapter may be
