AN ORDINANCE AMENDING CHAPTER 611, BUILDING
CODE, OF THE CODE OF ORDINANCES OF THE CITY
OF CAPE CANAVERAL, BREVARD COUNTY, FLORIDA;
REPEALING SECTION 611.10, APPENDIX "S",
COASTAL CONSTRUCTION BUILDING CODE, IN ITS
ENTIRETY; ADOPTING THE STATE OF FLORIDA 1986
MODEL COASTAL CONSTRUCTION BUILDING CODE;
REPEALING ALL PORTIONS OF THE CODE IN
CONFLICT HEREWITH; PROVIDING AN EFFECTIVE
DATE.
WHEREAS, the City of Cape Canaveral has previously adopted
the State of Florida's Model Coastal Construction Building Code;
and
WHEREAS, the State of Florida has amended said Code, it is
now incumbent upon the City to amend their coastal regulations;
NOW, THEREFORE, BE IT ORDAINED by the City Council of the
City of Cape Canaveral, Brevard County, Florida, as follows:
SECTION 1. Chapter 611, "Building Code ", is amended by
deleting Section 611.10 in its entirety and replacing with the
following:
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 contained
herein shall constitute the "Coastal Construction
Code" for construction within 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 severe storms
occurring along the coastal area of the City of Cape
Canaveral, which fronts on 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 properties.
The Coastal Code is site specific to the coastal build-
ing 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 the more restrictive design
shall apply. No provisions in this chapter shall be
construed to permit any construction in any area pro-
hibited by city, county, state or federal regulation.

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 vegeta-
tion, 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 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 characteris-
tic 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, Atlan-
tic Ocean, Florida Bay, or Straits of Florida, the
land area between the seasonal high -water line and a
line 1500 feet landward from the coastal construc-
tion 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
conditions as established by the Department of Natural
Resources in accordance with Section 161.053, Florida
Statutes.
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
alterations in the size or use of any existing struc-
ture or the appearance of any land. When appropriate
to the context, "construction" refers to the act of
construction or the result of construction.
Dune means a mound or ridge of loose sediments,
usually sand - sized, deposited by natural or artificial
means, which lies landward of the beach.
Major Structure includes but is not limited to
residential buildings including mobile homes, commer-
cial, 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 pri-
vate 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, aviar-
ies, and other ornamental construction. It shall be a
characteristic of minor structures that they are con-
sidered to be expendable under design wind, wave, and
storm forces.
Mobile Home means manufactured housing which con-
forms to the Federal Manufactured Housing Construction
and Safety Standards or the Uniform Standards Code ANSI
A -119.1 pursuant to Section 320.823, Florida Statutes.
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;

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.
Seasonal High -Water Line means the line formed by
the intersection of the rising shore and the elevation
of 150 percent of the local mean tidal range above mean
high water.
State Minimum Building Code means the Standard
Building Code referred to in Section 611.01 of this
Chapter.
Substantial Improvement means any repair, reconstruc-
tion, 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
structural 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 neces-
sary to assure safe living conditions; or any alter-
ation of a structure listed on the National Register of
Historic Places or the State Inventory of Historic
Places.
Sec. 611.104.1 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
damage may be found in the reference documents listed
in Section 611.105.1.
Sec. 611.104.2 Structural Requirements for Major
Structures.
A. Design and Construction. Major structures,
except for mobile homes, shall be designed and con-
structed in accordance with Section 1205 of the 1986
revisions to the 1985 Standard 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 construc-
tion 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.
ORDINANCE NO. 34 -86

C. Elevation, Floodproofing, and Siting. All
major structures shall be designed, constructed and
located in compliance with the National Flood Insur-
ance Regulations as found in 44 CFR Parts 59 and 60,
or Chapter 624, Flood Damage Prevention, whichever
is more restrictive.
Sec. 611.104.3 Design Conditions.
A. Velocity Pressure. Major structures, except
mobile homes, shall be designed in accordance with
the requirements of Section 1205 of the 1986 revi-
sions to the 1985 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 conditions. Foundation design and
construction of a major structure shall consider all
anticipated loads acting simultaneously with live
and dead loads. Erosion computations for foundation
design shall account for all vertical and lateral
erosion and scour producing forces, including local-
ized scour due to the presence of structural compo-
nents. Foundation design and construction 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 con-
trol lines established or updated since June 30,
1980. Upon request, the Department of Natural

Resources may provide 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
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 Protec-
tion 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 recog-
nized methodologies which produce equivalent design
criteria.
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.
D. Hydrostatic Loads. Calculations for hydro-
static loads shall consider the maximum water pres-
sure 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 eleva-
tion to which the confined water would freely rise
if unconfined. Vertical hydrostatic 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 surf-
aces. Hydrostatic loads on irregular or curved
geometric surfaces shall be determined by consider-
ing the separate vertical and horizontal components
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. 611.104.4 Structural Requirements for Nonhab-
itable 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 stand-
ards 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 condi-
tions. 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. 611.104.5 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 min-
imum adverse impact on the beach and dune system and
shall comply with the applicable standards of construc-
tion found in the Standard Building Code.
Sec. 611.104.6 Location of Construction. Con-
struction, 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 buf-
fering and protection capability of the dune is not
diminished.
Sec. 611.104.7 Public Access. Where the public has
established an accessway through private lands to lands
seaward of 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 conven-
ience to the public;
B. Approved by the local government and approved
by the Department of Natural Resources whenever
improvements are involved seaward of the coastal
construction control line; and
C. Consistent with the coastal management ele-
ment of the local comprehensive plan adopted pursu-
ant to Section 163.3178, Florida Statutes.
