ARTICLE I. IN GENERAL 
Sec. 17-l. Short Title. 
This cChapter shall be known as the Floodplain Management Ordinance of the City of 
Glendale with Rules and Regulations pursuant to the provisions of The Flood Disaster Protection 
Act and The National Flood Insurance Act, as amended.  
(Res. No. 4742, § 1(Exh. A),11-13-13) 
Sec. 17-2. Statutory authorization. 
Through A.R.S. § 48-3610 (Assumption of Powers and Duties), the Arizona State Legislature 
enabled the cCity of Glendale to assume the powers and duties for floodplain management and 
adopt regulations in conformance with A.R.S. § 48-36039 (Floodplain Delineation) designed to 
promote the public health, safety, and general welfare of its citizenry. Therefore, the City Council 
of Glendale, Arizona does ordain as follows: 
(Res. No. 4742, § 1(Exh. A), 11-13-13) 
Sec. 17-3. Findings of fact. 
(a) The Special fFlood hHazard aAreas of the cCity of Glendale are subject to periodic inundation 
which may results in loss of life and property, health and safety hazards, disruptions of 
commerce and governmental services, extraordinary public expenditures for flood protection 
and relief, and impairment of the tax base, all of which adversely affect the public health, 
safety, and general welfare.  
(b) These flood losses aremay be caused by the cumulative effect of obstructions in areas of 
sSpecial fFlood hHazards Areas which increase flood heights and velocities, and when 
inadequately anchored cause, damage uses in other areas. Uses that are inadequately 
floodproofed, elevated, or otherwise protected, from flood damage also contribute to the flood 
loss.  
(Res. No. 4742, § 1(Exh. A), 11-13-13) 
Sec. 17-4. Statement of Purpose. 
(a) It is Tthe purpose of this cChapter is to provide floodplain management regulations for all 
subdivision of land, construction of dwelling, commercial or industrial structures, or uses 
which may divert, retard or obstruct floodwater and threatenpromote public health, safety, 
orand the general welfare, and provide for the establishment of minimum flood protection 
elevations and flood damage prevention requirements for uses, structures and facilities which 
are vulnerable to flood damage; provide for the coordination by the council with all other 
interested and affected political subdivisions and state agencies, and to minimize public and 
private losses due to flood conditions in specific areas by provisions designed to:  
(1) To pProtect human life and health;

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 3 of 36 
 
(2) To mMinimize expenditure of public money for costly flood control projects;  
(3) To mMinimize the need for rescue and relief efforts associated with flooding and 
generally undertaken at the expense of the general public;  
(4) To mMinimize prolonged business interruptions;  
(5) To mMinimize damage to public facilities and utilities such as water mains, and gas 
mains, electric lines, telephone lines, and sewer lines, streets and bridges located in areas 
of sSpecial fFlood hHazard Areas;  
(6) To hHelp maintain a stable tax base by providing for the secondsound use and 
development of areas of sSpecial fFlood hHazard Areas so as to minimize future flood 
blight areas caused by flooding; and  
(7) To insure that potential buyers are notified that property is in an area of special flood 
hazard;  
(8) To insure that those who occupy the areas of special flood hazard assume responsibility 
for their actions; and,  
(97) To Participate in and maintain eligibility for stateflood insurance and disaster relief.  
 
Sec. 17-5. Methods of reducing flood loss. 
(ba) In order to accomplish its purposes, this cChapter includes methods and provisions forto:  
(1) Restricting or prohibiting uses which are dangerous to health, safety and property due to 
water or erosion hazards, or which result in damaging increases in erosion or in flood 
heights or velocities;  
(2) Requireing that uses vulnerable to floods, including facilities which serve such uses, be 
protected against flood damage at the time of initial construction;  
(3) Controlling the alteration of natural floodplains, stream channels, and natural protective 
barriers, which help accommodate or channel flood waters;  
(4) Controlling filling, grading, dredging, and other development which may increase flood 
damage; and,  
(5) Preventing or regulateing the construction of flood barriers which will unnaturally divert 
flood waters or which may increase flood hazards in other areas.  
(6) These regulations take precedence over any less restrictive conflicting local laws, 
ordinances and codes.

any source. See "fFlood or flooding."  
Floodplain Administrator: The public works administrator or his designee who is assigned to 
administer and enforce the floodplain management regulations.  
Floodplain Board: The City Council of the City of Glendale shall be the Floodplain Board. 
In the event the Floodplain Board must recuse itself from deciding a matter, the Board of Directors 
of the Flood Control District of Maricopa County shall hear such Floodplain disputes or floodplain 
variances to provide the appropriate enforcement of this ordinanceChapter.  
Floodplain management: The operation of an overall program of corrective and preventive 
measures for reducing flood damage and preserving and enhancing, where possible, natural 
resources in the floodplain, including but not limited to emergency preparedness plans, flood 
control works, floodplain management regulations, and open space plans. 
Floodplain management regulations: This Chapter and other Zzoning ordinances, 
subdivision regulations, building codes, health regulations, special purpose ordinances (such as 
floodplain ordinance, grading ordinance and erosion control ordinance) and other applications of 
police power which control development in flood-prone areas. Thise term describes such federal, 
state or local regulations in any combination thereof, which provide standards for the purpose 
ofpreventing and reducing flood loss and damage prevention and reduction.  
Floodproofed: Watertight with walls substantially impermeable to the passage of water and 
with structural components having the capability of restricting hydrostatic and hydrodynamic loads 
and effects of buoyancy.  
Floodproofing: Any combination of structural and nonstructural additions, changes, or 
adjustments to non-residential structures which reduce or eliminate risk of flood damage to real 
estate or improved real property, water and sanitary facilities, structures and their contents by 
means other than elevation.

hazard" and the extent of the depths of associated flooding. Such a system typically includes dams, 
reservoirs, levees or dikes. These specialized flood modifying works are those constructed in 
conformance with sound engineering standards.  
Flood-related erosion: The collapse or subsidence of land along the shore of a lake or other 
body of water as a result of undermining caused by waves or currents of water exceeding 
anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body 
of water, accompanied by a severe storm, or by an unanticipated force of nature, such as a flash 
flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which 
results in flooding.  
Flood-related erosion area or Flood-related erosion-prone area: A land area adjoining the 
shore of a lake or other body of water, which due to the composition of the shoreline or bank and 
high water levels or wind-driven currents, is likely to suffer flood-related erosion damage.  
Flood-related erosion area management: The operation of an overall program of corrective 
and preventative measures for reducing flood-related erosion damage, including but not limited to 
emergency preparedness plans, flood-related erosion control works, and floodplain management 
regulations.  
Floodway: The channel of a river or other watercourse and the adjacent land areas that must 
be reserved in order to discharge the base flood without cumulatively increasing the water surface 
elevation more than a designated height. Also referred to as the "Regulatory Floodway."  
Fraud and victimization: As related to Section 17-29 of this ordinance, means that the 
variance granted must not cause fraud on, or victimization of, the public. In examining this 
requirement, the City Council will consider the fact that every newly constructed building adds to 
government responsibilities and remains a part of the community for fifty to one hundred years. 
Buildings that are permitted to be constructed below the base flood elevation are subject during all 
those years to increased risk of damage from floods, while future owners of the property and the 
community as a whole are subject to all the costs, inconvenience, danger, and suffering that those 
increased flood damages bring. In addition, future owners may purchase the property, unaware 
that it is subject to potential flood damage, and can be insured only at very high flood insurance 
rates.  
Flood Zones: As shown on the Flood Insurance Rate Maps (FIRMs) by Title 44 CFR § 60.5, 
as amended. 
Zone A: No Base Flood Elevations determined. 
Zone AE: Base Flood Elevations determined. 
Zone AH: Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevations 
determined. 
Zone AO: Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths 
determined. For areas of alluvial fan flooding, velocities also determined. 
Zone X (unshaded): Areas determined to be outside the 0.2% annual chance floodplain.

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 8 of 36 
 
Zone X (shaded): Areas of 0.2% annual chance flood; areas of 1% annual chance flood with 
average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected 
by levees from 1% annual chance flood. 
Freeboard: An additional one (1) foot of height above the BFE is used as a factor of safety 
in determining the level at which a structure’s lowest floor must be elevated or dry floodproofed 
to be in accordance with this Chapter. 
Functionally dependent use: A use which cannot perform its intended purpose unless it is 
located or carried out in close proximity to water. The term includes only docking facilities, port 
facilities that are necessary for the loading and unloading of cargo or passengers, and ship building 
and ship repair facilities, but does not include long-term storage or related manufacturing facilities.  
Governing body: The local governing unit, i.e., county or municipality that is empowered to 
adopt and implement regulations to provide for the public health, safety and general welfare of its 
citizenry.  
Hardship: As referenced in Section 17-29 of this ordinanceChapter, the definition of 
exceptional hardship is the hardship be exceptional, unusual, and peculiar to the property involved. 
that would result from a failure to grant the requested variance. The Floodplain Board requires that 
the variance be exceptional, and peculiar to the property involved. Mere economic or financial 
hardship alone is not exceptional. Inconvenience, aesthetic considerations, physical handicaps, 
personal preferences, or the disapproval of one's neighbors likewise cannot, as a rule, qualify as 
an exceptional hardship. TheAll of these problems listed maycan be resolved, or may be required 
to be resolved, through other means without granting a floodplain variance, even if the alternative 
is more expensive, or requires the property owner to build elsewhere or put the parcel to a 
differentce use other than originally intended.  
Highest aAdjacent gGrade (HAG): The highest natural elevation of the ground surface prior 
to construction next to the proposed walls of a structure.  
Historic Structure: Any structure that is:  
(1) Listed individually in the National Register of Historic Places (a listing maintained by 
the Department of Interior) or preliminarily determined by the Secretary of the Interior 
as meeting the requirements for individual listing on the National Register;  
(2) Certified preliminarily determined by the Secretary of the Interior as contributing to the 
historical significance of a registered historic district or a district preliminarily 
determined by the Secretary to qualify as a registered historic district;  
(3) Individually listed on a state inventory of historic places in states with historic 
preservation programs which have been approved by the Secretary of Interior; or  
(4) Individually listed on a local inventory of historic places in communities with historic 
preservation programs that have been certified either:  
a. 
By an approved state program as determined by the Secretary of the Interior; or  
b. 
Directly by the Secretary of the Interior in states without approved programs.

structures, such as closure and drainage devices, which are constructed and operated in accordance 
with sound engineering practices.  
Lowest floor: The lowest floor of the lowest enclosed area, (including a basement)see 
“Basement”. An unfinished or flood resistant enclosure, usable solely for parking of vehicles, 
building access or storage in an area other than a basement area is not considered a building's 
lowest floor; provided, that such enclosure is not built so as to render the structure in violation of 
the applicable non-elevation design requirements of this cChapter.  
Manufactured home: A structure, transportable in one or more sections, which is built on a 
permanent chassis and is designed for use with or without a permanent foundation when 
attachedconnected to the required utilities. For floodplain management purposes the term 
"manufactured home'' also includes mobile homes, park trailers, travel trailers and other similar 
vehicles placed on a site for greater than one hundred eighty (180) consecutive daysThe term 
“manufactured home” does not include a “recreational vehicle”.

(FIRM) are referenced.  
New construction: For the purposes of determining insurance rates, structures for which the 
"start of construction" commenced on or after the effective date of an initial Flood Insurance Rate 
Map or after December 31, 1974, whichever is later, and includes any subsequent improvements 
to such structures. For floodplain management purposes, "new construction" means structures for 
which the "start of construction" commenced on or after December 6, 1984, and includes any 
subsequent improvements to such structure.  
New manufactured home park or manufactured home subdivision: A parcel (or contiguous 
parcels) of land divided into two (2) or more manufactured home lots for rent or sale for which the 
construction of facilities for servicing the lot (including, at a minimum, the installation of utilities,

velocity of the flow of water, or due to its location, its propensity to snare or collect debris carried 
by the flow of water, or its likelihood of being carried downstream.  
One-hundred-year flood or 100-year flood: The flood having a one percent (1%) chance of 
being equaled or exceeded in any given year. See "Base flood".

4001-4128, as amended.  
Program deficiency: A defect in a community's floodplain management regulations or 
administrative procedures that impairs effective implementation of those floodplain management 
regulations or of the NFIP standards.  
Public safety and nuisance: As related to Section 17-16 and 17-62 of this ordinanceChapter, 
means that the granting of a floodplain variance must not result in anything which is injurious to 
safety or health of an entire community or neighborhood, or any considerable number of persons, 
or unlawfully obstructs the free passage or use, in the customary manner, of any navigable lake, 
or river, bay, stream, canal, or basin.  
Reach: The longitudinal segments of a stream, wash or watercourse which may include, but 
not be limited to, the segment of the flood hazard area where flood heights are primarily controlled 
by man-made or natural obstructions or constrictions.  
Recreational vehicle. For purposes of this ArticleChapter only, a recreational vehicle is defined as 
a vehicle which is:  
(1) Built on a single chassis;  
(2) 400 square feet or less when measured at the largest horizontal projection;  
(3) Designed to be self-propelled or permanently towable by a light-duty truck; and  
(4) Designed primarily not for use as a permanent dwelling but as a temporary living 
quarters for recreational, camping travel, or seasonal use.  
Regulatory Flood Elevation (RFE): An elevation one (1) foot above the Base Flood Elevation 
for a watercourse for which the base flood elevation has been determined and shall be determined 
by the criteria developed by the Director of the Arizona Department of Water Resources for all 
other watercourses.  
Regulatory floodway: The channel of a river or other watercourse and the adjacent land areas 
that must be reserved in order to discharge the base flood without cumulatively increasing the 
water surface elevation more than a designated height. 
Remedy a violation: To bring the structure or other development into compliance with state 
or local floodplain management regulations, or, if this is not possible, to reduce the impacts of its 
noncompliance. Ways that impacts may be reduced include protecting the structure or other 
affected development from flood damages, implementing the enforcement provisions of the

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 11 of 36 
 
ordinanceChapter or otherwise deterring future similar violations, or reducing federal financial 
exposure with regard to the structure or other development.  
Riverine: Relating to, formed by, or resembling a river (including tributaries), stream, brook, 
etc.  
Sheet flow area: See "Area of shallow flooding".  
Special Flood Hazard Area (SFHA): An area in the floodplain subject to a one percent (1%) 
or greater chance of flooding in any given year. It is shown on the Flood Insurance Rate Map 
(FIRM) as zZone A, AO, AHl-30, or AE, A99 or AH.  
Start of construction: Includes substantial improvement and other proposed new development 
and means the date the building permit was issued, provided the actual start of construction, repair, 
reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days 
from the date of the permit. The actual start date means either the first placement of permanent 
construction of a structure on a site, such as the pouring of slabs or footings, the installation of 
piles, the construction of columns, or any work beyond the stage of excavation; or the placement 
of a manufactured home on a foundation. Permanent construction does not include land 
preparation, such as clearing, grading, and filling; nor does it include the installation of streets 
and/or walkways; nor does it include excavation for a basement, footing, piers or foundations or 
the erection of temporary forms; nor does it include the installation on the property of accessory 
buildings, such as garages or sheds not occupied as dwelling units or not as part of the main 
structure. For a substantial improvement, the actual start of construction means the first alteration 
of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration 
affects the external dimensions of the building.  
Structure: A walled and roofed building, including a gas or liquid storage tank that is 
principally above ground; a manufactured home is a structure. For floodplain management 
purposes, a structure is a walled and roofed building that is principally above ground, where walled 
is considered “two or more outside rigid walls” and roofed is “a fully secured roof.” The term 
includes gas and liquid storage tanks and manufactured homes. The terms “structure” and 
“building” are used interchangeably in the NFIP regulations and this bulletin. Floodplain managers 
must use professional judgment to determine which proposed development projects are “walled 
and roofed,” and thus regulated as structures, and which proposed projects are regulated as 
development. 
Substantial damage: Damage of any origin sustained by a structure whereby the cost of 
restoring the structure to its before-damaged condition would equal or exceed fifty percent (50%) 
of the market value of the structure before the damage occurred.  
Substantial improvement: Any reconstruction, rehabilitation, addition, or improvement tof a 
structure, the cost of which equals or exceeds fifty percent (50%) of the market value of the 
structure before the "start of construction" of the improvement. This term includes structures which 
have incurred "substantial damage," regardless of the actual repair work performed. However, the 
term does not include either:  
(1) Any project for improvement of a structure required to comply with existing violations 
or to comply with state or local health, sanitary or safety code specifications which have

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 12 of 36 
 
been identified by the local code enforcement official and which are the minimum 
necessary to assure safe living conditions; or

b. 
Review all development permits to determine that all necessaryrequired permits 
have been obtained from those federal, state or local governmental agencies from 
which prior approval is required.  
c. 
Review all development permits to determine if the proposed development 
adversely affects the flood carrying capacity of the area of special flood hazard. For 
purposes of this chapter, "adversely affects" means that the cumulative effect of the 
proposed development when combined with all other existing and anticipated 
development will not increase the water surface elevation of the base flood more 
than one (1) foot at any point.  
dc. Determine that the site is reasonably safe from flooding.

Sec. 17-29. Variance Procedures; Nature of Variances; Appeals. 
(a) Nature of Variances. The variance criteria set forth in this section of the ordinance are based 
on the general principle of zoning law that variances pertain to a piece of property and are not 
personal in nature. A variance may be granted for a parcel of property with physical

characteristics so unusual that complying with the requirements of this ordinance would 
create an exceptional hardship to the applicant or the surrounding property owners. The 
characteristics must be unique to the property and not be shared by adjacent parcels. The 
unique characteristic must pertain to the land itself, not to the structure, its inhabitants or the 
property owners.  
(b) It is the duty of the City of Glendale to help protect its citizens from flooding. This need is so 
compelling and the implications of the cost of insuring a structure built below the regulatory 
flood elevation are so serious that variances from the flood elevation or from other 
requirements in the flood ordinance are rare. The long-term goal of preventing and reducing 
flood loss and damage can only be met if variances are strictly limited. Therefore, the variance 
guidelines provided in this ordinance are more detailed and contain multiple provisions that 
must be met before a variance can be properly granted. The criteria are designed to screen out 
those situations in which alternatives other than a variance are more appropriate.  
(c) Administrative Appeals Board.  
(1) The Administrative Appeals Board of the City of Glendale shall hear and decide appeals 
and requests for variances from the requirements of this ordinance.  
(2) The Administrative Appeals Board shall hear and decide appeals when it is alleged there 
is an error in any requirement, decision, or determination made by the Floodplain 
Administrator in the enforcement or administration of this ordinance.  
(3) In passing upon such applications, the Administrative Appeals Board shall consider all 
technical evaluations, all relevant factors, standards specified in other sections of this 
ordinance, and:  
a. 
The danger that materials may be swept onto other lands to the injury of others;  
b. 
The danger of life and property due to flooding or erosion damage;  
c. 
The susceptibility of the proposed facility and its contents to flood damage and the 
effect of such damage on the individual owner;  
d. 
The importance of the services provided by the proposed facility to the community;  
e. 
The necessity to the facility of a waterfront location, where applicable;  
f. 
The availability of alternative locations for the proposed use, which are not subject 
to flooding or erosion damage;  
g. 
The compatibility of the proposed use with existing and anticipated development;  
h. 
The relationship of the proposed use to the comprehensive plan and floodplain 
management program for that area;  
i. 
The safety of access to the property in time of flood for ordinary and emergency 
vehicles;  
j. 
The expected heights, velocity, duration, rate of rise, and sediment transport of the 
flood waters expected at the site; and,

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 25 of 36 
 
k. 
The costs of providing governmental services during and after flood conditions, 
including maintenance and repair of public utilities and facilities such as sewer, gas, 
electrical, water system and streets and bridges.  
(4) Upon consideration of the factors of Section 17-29(c) and the purposes of this ordinance, 
the Administrative Appeals Board may attach such conditions to the granting of 
variances as it deems necessary to further the purposes of this ordinance.  
(5) Any applicant to whom a variance is granted shall be given written notice over the 
signature of a community official that:  
a. 
The issuance of a variance to construct a structure below the base flood level will 
result in increased premium rates for flood insurance up to amounts as high as 
$25.00 for $100.00 of insurance coverage, and  
b. 
Such construction below the base flood level increases risks to life and property; 
and  
c. 
The land upon which the variance is granted shall be ineligible for exchange of state 
land pursuant to the flood relocation and land exchange program provided by 
A.R.S. § 26-301 et seq., as amended. A copy of the notice shall be recorded in the 
office of the Maricopa County Recorder and shall be recorded in a manner so that 
it appears in the chain of title of the affected parcel of land.  
(6) The Floodplain Administrator shall maintain a record of all variance actions, including 
justification for their issuance and report such variances issued in its biennial report 
submitted to Federal Emergency Management Agency.  
(d) Conditions for variances.  
(1) Generally, variances may be issued for new construction and substantial 
improvements to be erected on a lot of one-half acre or less in size contiguous to 
and surrounded by lots with existing structures constructed below the base flood 
elevation, provided the procedures of Articles II and III of this ordinance have been 
fully considered. As the lot size increases beyond one-half acre, the technical 
justification required for issuing the variance increases.  
(2) Variances may be issued for the repair, rehabilitation or restoration of structures 
listed in the National Register of Historic Places or the State Inventory of Historic 
Places, upon a determination that the proposed repair or rehabilitation will not 
preclude the structures continued designation as a historic structure and the variance 
is the minimum necessary to preserve the historic character and design of the 
structure.  
(3) Variances shall not be issued within any designated floodway if any increase in flood 
levels during the base flood discharge would result.  
(4) Variances shall only be issued upon a determination that the variance is the minimum 
necessary, considering the flood hazard, to afford relief.  
(5) Variances shall only be issued upon a:

(Additions are indicated by underline; deletions by strikethrough) 
 
Page 26 of 36 
 
a. 
Showing of good and sufficient cause;  
b. 
Determination that failure to grant the variance would result in exceptional hardship 
to the applicant;  
c. 
Showing that the use cannot perform its intended purpose unless it is located or 
carried out in close proximity to water. This includes only facilities defined in 
Section 17-5 of this ordinance in the definition of "Functionally Dependent Use"; 
and,  
d. 
Determination that the granting of a variance will not result in increased flood 
heights, additional threats to public safety, extraordinary public expense, create 
nuisances, cause fraud on or victimization of the public or conflict with existing 
local laws or ordinances.  
e. 
Any variance granted must be recommended to, and approved by, the City Council 
acting as the Floodplain Board.

ARTICLE V. FLOODPLAIN VARIANCE PROCEDURE 
Sec. 17-61. Floodplain Variance Procedures; Nature of Floodplain Variances; Appeals. 
(a) Nature of Floodplain Variances. The floodplain variance criteria set forth in this section of 
the Chapter are based on the general principle of zoning law that variances pertain to a piece 
of property and are not personal in nature. A floodplain variance may be granted for a parcel 
of property with physical characteristics so unusual that complying with the requirements of 
this Chapter would create an exceptional hardship to the applicant or the surrounding property

owners. The characteristics must be unique to the property and not be shared by adjacent 
parcels. The unique characteristic must pertain to the land itself, not to the structure, its 
inhabitants, or the property owners.  
(b) It is the duty of the City of Glendale to help protect its citizens from flooding. This need is so 
compelling and the implications of the cost of insuring a structure built below the rRegulatory 
fFlood eElevation are so serious that floodplain variances from the flood elevation or from 
other requirements in the flood ordinance are rare. The long-term goal of preventing and 
reducing flood loss and damage can only be met if floodplain variances are strictly limited. 
Therefore, the floodplain variance guidelines provided in this Chapter are more detailed and 
contain multiple provisions that must be met before a floodplain variance can be properly 
granted. The criteria are designed to screen out those situations in which alternatives other 
than a floodplain variance are more appropriate.  
(c) Administrative Appeals Board.  
(1) The Administrative Appeals Board of the City of Glendale shall hear and decide appeals 
and requests for floodplain variances from the requirements of this Chapter.  
(2) The Administrative Appeals Board shall hear and decide appeals when it is alleged there 
is an error in any requirement, decision, or determination made by the Floodplain 
Administrator in the enforcement or administration of this ordinance.  
(3) In considering such applications, the Administrative Appeals Board shall consider all 
technical evaluations, all relevant factors, standards specified in other sections of this 
Chapter, and:  
a. 
The danger that materials may be swept onto other lands to the injury of others;  
b. 
The danger of life and property due to flooding or erosion damage;  
c. 
The susceptibility of the proposed facility and its contents to flood damage and the 
effect of such damage on the individual owner;  
d. 
The importance of the services provided by the proposed facility to the community;  
e. 
The necessity to the facility of a waterfront location, where applicable;  
f. 
The availability of alternative locations for the proposed use, which are not subject 
to flooding or erosion damage;  
g. 
The compatibility of the proposed use with existing and anticipated development;  
h. 
The relationship of the proposed use to the comprehensive plan and floodplain 
management program for that area;  
i. 
The safety of access to the property in time of flood for ordinary and emergency 
vehicles;  
j. 
The expected heights, velocity, duration, rate of rise, and sediment transport of the 
flood waters expected at the site; and,

k. 
The costs of providing governmental services during and after flood conditions, 
including maintenance and repair of public utilities and facilities such as sewer, gas, 
electrical, water system and streets and bridges.  
(4) Upon consideration of the factors of Section 17-61(c) and the purposes of this Chapter, 
the Administrative Appeals Board may attach such conditions to the granting of 
floodplain variances as it deems necessary to further the purposes of this Chapter.  
(5) Any applicant to whom a floodplain variance is granted shall be given written notice 
over the signature of a community official that:  
a. 
The issuance of a variance to construct a structure below the Regulatory Base Flood 
Elevation will result in increased premium rates for flood insurance up to amounts 
as high as $25.00 for $100.00 of insurance coverage, and  
b. 
Such construction below the base flood level increases risks to life and property; 
and  
(6) The Floodplain Administrator shall maintain a record of all floodplain variance actions, 
including justification for their issuance. 
Sec. 17-62. Conditions for a Floodplain Variance. 
(a) Conditions for floodplain variance shall only be issued:  
(1) Upon a determination that the granting of a floodplain variance will not result in 
increased flood heights, additional threats to public safety, extraordinary public expense, 
create nuisances, cause fraud, victimization of the public, or conflict with existing local 
laws, Chapters or ordinances  
(2) Upon a determination that the floodplain variance is the minimum necessary, 
considering the flood hazard, to afford relief.  
(3) Floodplain Variances shall not be issued within any floodway if any increase in the Base 
Flood Elevation would result. 
(4) Upon showing of good and sufficient cause: 
a. 
Upon determination that failure to grant the floodplain variance would result in 
exceptional hardship to the applicant; and 
b. 
Upon showing that the use cannot perform its intended purpose unless it is located 
or carried out in close proximity to water. This includes only facilities defined in 
Section 17-6 of this Chapter in the definition of "Functionally Dependent Use".   
(5) 
Generally, floodplain variances may be issued for new construction and substantial 
improvements to be erected on a lot of one-half acre or less in size contiguous to and 
surrounded by lots with existing structures constructed below the Regulatory Flood 
Elevation, provided the procedures of Articles II and III of this chapter have been fully 
considered. As the lot size increases beyond one-half acre, the technical justification 
required for issuing the floodplain variance increases.
