the floodwaters and the effects of wave action, if applicable, expected at the site; and
1 Q. The costs of providing govemmental services during and after flood conditions including
maintena.nce and repair of public utilities and facilities such as sewer, gas, electrical and
water systems, streets and bridges.
Sec. 78-818. Conditions for issu�nce of variances. Variances shall be issued only upon:
1. Submission by the applicant, of a showing of good and sufficient cause that the unique
characteristics of the size, configuration, or topography of the site render any provision of
this article or the elevation standards of the Florida Buildzng Code inappropriate;
2. Determination by the Board of Adjustment that:
a. Failure to grant the variance would result in exceptional hazdship due to the
physical characteristics of the land that render the lot wndevelopable; increased
costs to satisfy the requirements or inconvenience do not constitute hardship;
b. The granting of a variance will not result in increased flood heights, additional
threats to public safety, extraordinary public expense, nor create nuisances, cause
fia.ua on or vicrimization of the public or conflict with existing local laws and
ordinances; and
c. The variance is the minimum necessary, considering the flood hazard, to afford
relief;
3. Receipt of a signed statement by the applicant that the variance, if granted, sha11 be
recorded in the Office of the Clerk of the Court in such a manner that it a�pears in the
chain of title of the affected parcel of land; and
4. If the request is for a variance to a11ow construction of the lowest floor of a building, or
substantial improvement of a building, below the elevation required by the Fdorfda
Building Code or required by this article a c�py in the record of a written notice from the
Floodplain Administrator to the applicant for the variance, specifying the difference
between the base flood elevation and the proposed. elevation of the lowest floor, stating
that the cost of federal flood insurance will be commensurate with the increased risk
resulting from the reduced floor elevation (up to amounts as high as$25 for $100 of
insurance coverage), and stating that construction below the base flood elevation
increases risks to life and property.

walls and sidewalks and driveways that involve the placement of fill in regulated floodways shall
meet the limitations of Sec. 78-841 of this article.
Sec. 78-SS7. Roads and watercourse crossings in regulated floodways. Roads a.nd
watercourse crossings, including roads, bridges, culverts, low-water crossings and similar means
for vehicles or pedestrians to travel from one side of a watercourse to the other side, that
encroach into regulated floodways sha11 meet the limita.tions of Sec. 78-841 of this article.
Alteration of a watercourse that is part of a road or watercourse crossing shall meet the
requirements of Sec. 78-803 of this article.
Sec. 78-858. Concrete slabs used as parl�ng pads, enclosure floors, landings, decks,
walkways, patios and similar nonstructural uses in coastal high hazard areas (Zone �. In
coastal high hazard areas, cancrete slabs used as parki.ng pads, enclosure floors, landings, decks,
walkways, patios and similar nonstructural uses are pernutted beneath or adjacent to buildings
and structures provided the concrete slabs are designed and constructed to be:
1. Structurally independent of the foundation system of the building or structure;
2. Frangible and not reinforced, so as to minimi�e debris during flooding that is capable of
causing significant damage to any structure; and
3. Have a maximum slab thickness of not more than four (4) inches.
Sec. 78-859. Decks and patios in coastal high hazard areas (Zone �. In addition to the
requirements of the Florida Building Code, in coastal high hazard areas decks and patios sha11 be
located, designed, and constructed in compliance with the following:
1. A deck that is structurally atta.ehed to a building or structure shall have the bottom of the
lowest horizontal structural member at or above the design flood elevation and any
supporting members that extend below the design flood elevation shall comply with the
foundation requirements that apply to the building or structure, which shall be designed
to accommodate any increased loads resulting from the attached deck.
2. A deck or patio that is located below the design flood elevation sha11 be structurally
independent from buildings and shuctures and their foundation systems, and shall be
designed and constructed either to remain intact and in place during design flood
conditions or to break apart into sma11 pieces to min;mi�e debris during flooding that is
capable of causing structural damage to adjacent elevated buildings and structures.
3. A deck or patio that has a vertical thickness of more than twelve (12) inches or that is
constructed with more than the minimum amount of fill necessary for site drainage shall
not be approved unless an analysis prepared by a qualified registered design professional
demonstrates no hannful diversion of floodwaters or wave runup and wave reflection that
would increase damage to adjacent buildi.ngs and structures.
25 �
4. A deck or patio that has a vertical thickness of twelve (12) in.ches or less and that is at
naiural grade or on nonstructural fill material that is similar to and compatible with local
soils and is the minimum amount necessary for site drainage may be approved without
requiring analysis of the impact on diversion of floodwaters or wave runup and wave
reflection.
Sec. 78-860. Other development in coastal high hazard areas (Zone �. In coastal high
hazazd areas, development activities other than buildings and structures shall be permitted only if
authorized by the appropriate state or local authority; if located outside the footprint of, and not
structurally atta.ched to, buildings and structures; and if analyses prepared by qualified registered
design professionals demonstrate no harmful diversion of floodwaters or wave runup and wave
reflection that would increase damage to adjacent elevated buildings and structures. Such other
development activities include but aze not limited to:
1. Bulkheads, seawalls, retaining wa11s, revetments, and similar erosion control structures;
2. Solid fences and privacy wa11s, and fences prone to trapping debris, unless designed and
consixucted to fa.il under flood conditions less than the design flood or otherwise function
to avoid obstruction of floodwaters; and
3. 4n-site sewage treatment and disposal systems defined in 64E-6.002, F.A.C., as filled
systems or mound systems.
Sec. 78-861. Nonstructural fill in coastal high hazard areas (Zone �. In coastal high hazard
areas:
l. Minor grading and the placement of minor quantities of nonstructural fill shall be
permitted for landscaping and for drainage purposes under and around buildings.
2. Nonstructural fill with finished slopes that are steeper than one unit vertical to five units
horizontal shall be permitted only if an analysis prepared by a qualified registered design
professional demonstrates no harmful diversion of floodwaters or wave runup and wave
reflection that would increase damage to adjacent buildings and structures.
3. Where authorized by the Florida. Department of Environmental Protection or applicable
local approval, sand dune construction and restoration of sand dunes under or around
elevated buildings are permitted without additional engineering analysis or certification
of the diversion of floodwater or wave runup or wave reflection if the scale and location
of the dune work is consistent with local beach-dune morphology and the vertical
clearance is maintained between the top of the sand dune and the lowest horizontal
structural member of the building.
