County
(a) Plans shall show that construction of the 'Lowest finished floor meets the
elevation criteria listed below or engineered properly to a site specific design and
certified by a Registered architect or Professional engineer; when conflict exists
between the FIRM Elevation and others, the higher elevation shall be required:
i. FIRM Elevation - the elevation that has been established by the Flood
Insurance Study (FIS).
ii. Paved Road - a minimum of 18 inches above the crown of the nearest street or
interior finished roadway system if finished with paving; in the event that the
nearest street or interior finished roadway system is located on an evacuation
route, a minimum of 18 inches above the crown of the nearest side street; or
iii. Graded or unfinished Road - 24 inches above the crown if graded or otherwise
unfinished, or
iv. Mean Sea Level — Finished Lowest Ffloors should be no lower than
elevation 5.7 feet in relation to NAVD of 1988 Jwith an allowable exception
for the bottom of the lowest horizontal structural member of the Lowest floor
of accessory structures within the V-Zones as described in SECTION FIVE
(DX13)(h)] or
v. Water Management Design-
1. Buildings with projects which have water management routing and
storage facilities designed and built for a 25 year, 3 day storm event in
accordance with South Florida Water Management District's criteria may
use a finished Lowest floor elevation in accordance with the project's
water management designed 100 year zero discharge elevation or the
FIRM elevation, whichever is higher.
2. Buildings which are not within projects having water management storage
facilities designed and built for a 25 year, 3 day storm event in accordance
with South Florida Water Management District's criteria shall use a
finished Lowest floor elevation of 18 inches above the adjacent roadway
crown elevation or the FIRM elevation, whichever is higher.
(b) On parcels where unusual topographic conditions exist and the above standard
conditions cannot be reasonably applied, the Building Official will consider
requests to decrease the finished Lowest floor elevation. All requests will require
an analysis, by a Professional engineer, of the 25 year, three (3) day storm event
and the 100 year, 3 day storm event using zero discharge, for the entire discharge,
for the entire drainage basin in which the proposed Structure is located.
Reductions may be allowed on the basis of the analysis, but in no case shall the
finished Lowest floor be less than the FIRM.
(c) Slabs for garages, carports, screen enclosures, etc., must be at least equal in
elevation to the crown of the nearest street.

Page 9 of 11
(2) Variances may be issued for New construction and Substantial improvements and
for other Development necessary for the conduct of a Functionally dependent use
provided that
a) The criteria of Sub-section F, and Paragraphs (1), (3) and (4) of this Sub-section D
are met, and
b) The Structure or other Development is protected by methods that minimize
Flood damages during the Base flood and create no additional threats to Public
safety.
(3) Variances shall only be issued when there is:
a) A showing of good and sufficient cause;
b) A determination that failure to grant the Variance would result in exceptional
Hardship; and
c) A determination that the granting of a Variance will not result in increased Flood
heights, additional threats to Public safety or extraordinary public expense, cause
fraud on or victimization of the public, or conflict with existing local laws or
ordinances.
(4) Variances shall only be issued upon a determination that the Variance is the minimum
necessary deviation from the requirements of this Ordinance, considering the Flood
hazard, to afford relief.
(5) The County Manager shall maintain the records of all Variance actions and report any
Variances to the Federal Insurance Administration upon request.
(6) Any applicant to whom a Variance is granted shall be given written notice that
when a Structure is permitted to be built with the ILowest habitable floor elevation
below the BFE the cost of Flood insurance will be commensurate with the increased
risk resulting from the rased ILowest floor being placed
below the Base flood elevation.
(7) Upon consideration of the factors listed above and the purpose of this Ordinance, the
Board of Zoning Appeals may attach such conditions to the granting of Variances as it
deems necessary to further the purposes of this Ordinance.
E. HISTORIC STRUCTURES.
Variances may be issued for the feeenstftietien7 repair or rehabilitation or--restoration of
Historic Structures structures - - • . . • - - . - • • ' - --
upon a determination that the proposed repair or rehabilitation will not preclude the

structure's continued designation as a Historic structure and the variance is the minimum
necessary deviation from the requirements of this Ordinance to preserve the historic
character and design of the structure.
F. STRUCTURES IN REGULATORY FLOODWAY.
Variances shall not be issued within any designated Floodway if any impact in Flood
conditions or increase in Flood levels during the Base flood discharge would result.
SECTION FIVE: INCLUSION IN THE CODE OF LAWS AND ORDINANCES.
The provisions of this Ordinance shall be made a part of the Code of Laws and
Ordinances of Collier County, Florida. The Sections of the Ordinance may be renumbered or re-
lettered to accomplish such, and the word "Ordinance" may be changed to "section," "article," or
