and enhance community and economic development.
As used in this chapter, the following terms shall have the
meanings indicated:
The flood having a one-percent probability of being equaled or exceeded in any given year. The base flood is also known as the "one-hundred-year flood." The base flood elevation at any location is as defined in § 133-3 of this chapter.
The elevation in relation to mean sea level of the crest
of the base flood.
That portion of a building having its floor subgrade (below
ground level) on all sides.
A walled and roofed structure, including a gas or liquid
storage tank that is principally above ground, including manufactured
homes, prefabricated buildings and gas or liquid storage tanks. The
term also includes recreational vehicles and travel trailers installed
on a site for more than 180 days per year.
Any facility which is critical to the health and welfare of
the population and, if flooded, would create an added dimension to
the disaster. Damage to these critical facilities can impact the delivery
of vital services, can cause greater damage to other sectors of the
community, or can put special populations at risk.
Examples of critical facilities where flood protection should
be required include: emergency services facilities (such as fire and
police stations), schools, hospitals, retirement homes and senior
care facilities, major roads and bridges, critical utility sites (telephone
switching stations or electrical transformers), and hazardous material
storage facilities (chemicals, petrochemicals, hazardous or toxic
substances).

limited to:
Demolition, construction, reconstruction, repair, placement
of a building, or any structural alteration to a building;
Substantial improvement of an existing building;
Installation of a manufactured home on a site, preparing a site
for a manufactured home, or installing a travel trailer on a site
for more than 180 days per year;
Installation of utilities, construction of roads, bridges, culverts
or similar projects;
Construction or erection of levees, dams, walls or fences;
Drilling, mining, filling, dredging, grading, excavating, paving,
or other alterations of the ground surface;
Storage of materials, including the placement of gas and liquid
storage tanks, and channel modifications or any other activity that
might change the direction, height, or velocity of flood or surface
waters.
"Development" does not include routine maintenance of existing
buildings and facilities, resurfacing roads, or gardening, plowing,
and similar practices that do not involve filling, grading, or construction
of levees.
A manufactured home park or subdivision for which the construction
of facilities for servicing the lots on which the manufactured homes
are to be affixed or buildings to be constructed (including, at a
minimum, the installation of utilities, the construction of streets,
and either final site grading or the pouring of concrete pads) is
completed before the effective date of the floodplain management regulations
adopted by a community.
The preparation of additional sites by the construction of
facilities for servicing the lots on which the manufactured homes
are to be affixed (including the installation of utilities, the construction
of streets, and either final site grading or the pouring of concrete
pads).
The Federal Emergency Management Agency.
A general and temporary condition of partial or complete
inundation of normally dry land areas from the overflow, the unusual
and rapid accumulation, or the runoff of surface waters from any source.
That portion of the floodplain outside of the regulatory
floodway.
A map prepared by the Federal Emergency Management Agency
that depicts the floodplain or special flood hazard area (SFHA) within
a community. This map includes insurance rate zones and may or may
not depict floodways and show base flood elevations.
An examination, evaluation and determination of flood hazards
and, if appropriate, corresponding water surface elevations.
The elevation of the base flood plus one foot of freeboard
at any given location in the floodplain.
These two terms are synonymous. Those lands within the jurisdiction
of the Village of Sidney, the extraterritorial jurisdiction of the
Village of Sidney, or that may be annexed into the Village of Sidney,

of the Village are generally identified as such on panel number(s)
17019C0475D of the countywide Flood Insurance Rate Map of Champaign
County prepared by the Federal Emergency Management Agency and dated
October 2, 2013. "Floodplain" also includes those areas of known flooding
as identified by the community. The floodplains of those parts of
unincorporated Champaign County that are within the extraterritorial
jurisdiction of the Village of Sidney or that may be annexed into
the Village of Sidney are generally identified as such on the Flood
Insurance Rate Map prepared for Champaign County by the Federal Emergency
Management Agency and dated October 2, 2013.
Any combination of structural or nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood
damage to real estate, property and their contents.
A form published by the Federal Emergency Management Agency
that is used to certify that a building has been designed and constructed
to be structurally dry floodproofed to the flood protection elevation.
That portion of the floodplain required to store and convey
the base flood. The floodway for the floodplains of the Right Bank
Tributary of the Salt Fork River shall be as delineated on the countywide
Flood Insurance Rate Map of Champaign County prepared by FEMA and

Illinois Department of Natural Resources/Office of Water
Resources.
The Illinois Department of Natural Resources Office of Water Resources has jurisdiction over any stream serving a tributary area of 640 acres or more in an urban area, or in the floodway of any stream serving a tributary area of 6,400 acres or more in a rural area. Construction on these streams requires a permit from the Department (17 Ill. Admin. Code 3700.30). The Department may grant approval for specific types of activities by issuance of a statewide permit which meets the standards defined in § 133-6 of this chapter.
The lowest floor of the lowest enclosed area (including 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 nonelevation design requirements of § 133-7 of this chapter.

completed on or after the effective date of the floodplain management
regulations adopted by a community.
The National Flood Insurance Program.
A vehicle which is:
Flood-related damages sustained by a structure on two separate
occasions during a ten-year period for which the cost of repairs at
the time of each such flood event on the average equals or exceeds
25% of the market value of the structure before the damage occurred.
See "floodplain."
Includes substantial improvement 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 of the permit date. The "actual start" means either
the first placement of permanent construction of a structure on a
site, such as the pouring of slab or footings, the installation of
piles, the construction of columns or any work beyond the stage of
excavation or placement of a manufactured home on a foundation. For
a substantial improvement, "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.
See "building."
Damage of any origin sustained by a structure whereby the
cumulative percentage of damage during the life of the building equals
or exceeds 50% of the market value of the structure before the damage
occurred, regardless of actual repair work performed. Volunteer labor
and materials must be included in this determination. The term includes
"repetitive loss" buildings (see definition).
Any reconstruction, rehabilitation, addition or improvement
of a structure taking place during the life of the building in which
the cumulative percentage of improvements:
"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. This term includes structures
which have incurred repetitive loss or substantial damage, regardless
of the actual repair work done.
The term does not include:
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 alteration of a structure listed on the National Register
of Historic Places or the Illinois Register of Historic Places.
The failure of a structure or other development to be fully
compliant with the community's floodplain management regulations.
A structure or other development without the required federal, state,
and/or local permits and elevation certification is presumed to be
in violation until such time as the documentation is provided.

Village Zoning Board of Appeals for a variance. The Zoning Board of
Appeals shall review the applicant's request for a variance and shall
submit its recommendation to the Board of Trustees. The Board of Trustees
may attach such conditions to the granting of a variance as it deems
necessary to further the intent of this chapter.
A.Â
No variance shall be granted unless the applicant demonstrates that
all of the following conditions are met:
(1)Â
The development activity cannot be located outside the floodplain;
(2)Â
An exceptional hardship would result if the variance were not granted;
(3)Â
The relief requested is the minimum necessary;
(4)Â
There will be no additional threat to public health, safety or creation
of a nuisance;
(5)Â
There will be no additional public expense for flood protection,
rescue or relief operations, policing, or repairs to roads, utilities,
or other public facilities;
(6)Â
The applicant's circumstances are unique and do not establish a pattern
inconsistent with the intent of the NFIP; and
(7)Â
All other state and federal permits have been obtained.
B.Â
The Zoning Board of Appeals shall notify an applicant in writing that a variance from the requirements of the building protection standards of § 133-7 that would lessen the degree of protection to a building will:
(1)Â
Result in increased premium rates for flood insurance up to $25 per
$100 of insurance coverage;
(2)Â
Increase the risk to life and property; and
(3)Â
Require that the applicant proceed with knowledge of these risks
and that the applicant acknowledge in writing the assumption of the
risk and liability.
C.Â
Historic structures. Variances to the building protection requirements of § 133-7 of this chapter which are requested in connection with reconstruction, repair, or alteration of an historic site or historic structure as defined in "historic structures" in § 133-2 may be granted using criteria more permissive than the requirements of §§ 133-6 and 133-7 of this chapter subject to the conditions that:
D.Â
Agriculture. Any variance granted for an agricultural structure shall
be decided individually based on a case-by-case analysis of the building's
unique circumstances. Variances granted shall meet the following conditions
as well as those criteria and conditions set forth in this chapter.
In order to minimize flood damages during the one-hundred-year flood
and the threat to public health and safety, the following conditions
shall be included for any variance issued for agricultural structures
that are constructed at-grade and wet-floodproofed:
(1)Â
All agricultural structures considered for a variance from the floodplain
management regulations of this chapter shall demonstrate that the
varied structure is located in wide, expansive floodplain areas and
no other alternate location outside of the special flood hazard area
exists for the agricultural structure. Residential structures or animal
confinement facilities, such as farm houses, cannot be considered
agricultural structures.
(2)Â
Use of the varied structures must be limited to agricultural purposes
in Zone A only as identified on the community's Flood Insurance Rate
Map (FIRM).
(3)Â
For any new or substantially damaged agricultural structures, the exterior and interior building components and elements (i.e., foundation, wall framing, exterior and interior finishes, flooring, etc.) below the base flood elevation must be built with flood-resistant materials in accordance with § 133-7 of this chapter.
(4)Â
The agricultural structures must be adequately anchored to prevent flotation, collapse, or lateral movement of the structures in accordance with § 133-7 of this chapter. All of the buildings' structural components must be capable of resisting specific flood-related forces, including hydrostatic, buoyancy, and hydrodynamic and debris impact forces.
(5)Â
Any mechanical, electrical, or other utility equipment must be located above the base flood elevation or floodproofed so that they are contained within a watertight, floodproofed enclosure that is capable of resisting damage during flood conditions in accordance with § 133-7 of this chapter.
(6)Â
The NFIP requires that enclosure or foundation walls, subject to the one-hundred-year flood, contain openings that will permit the automatic entry and exit of floodwaters in accordance with § 133-7B of this chapter.
(7)Â
The agricultural structures must comply with the floodplain management floodway provisions of § 133-6 of this chapter. No variances may be issued for agricultural structures within any designated floodway.
(8)Â
Wet-floodproofing construction techniques must be reviewed and approved
by the floodplain administrator and a registered professional engineer
or architect prior to the issuance of any floodplain development permit
for construction.
The degree of protection required by this chapter is considered
reasonable for regulatory purposes and is based on available information
derived from engineering and scientific methods of study. Larger floods
may occur or flood heights may be increased by man-made or natural
causes. This chapter does not imply that development either inside
or outside of the floodplain will be free from flooding or damage.
This chapter does not create liability on the part of the Village
or any officer or employee thereof for any flood damage that results
from proper reliance on this chapter or any administrative decision
made lawfully thereunder.
Failure to obtain a permit for development in the floodplain
or failure to comply with the conditions of a permit or a variance
shall be deemed to be a violation of this chapter. Upon due investigation,
the, BPO/ZA may determine that a violation of the minimum standards
of this chapter exists. The BPO/ZA shall notify the owner in writing
of such violation.
A.Â
If such owner fails after 10 days' notice to correct the violation:
(1)Â
The Village shall make application to the circuit court for an injunction
requiring conformance with this chapter or make such other order as
the court deems necessary to secure compliance with this chapter.
(2)Â
Any person who violates this chapter shall, upon conviction thereof,
be fined not less than $50 nor more than $750 for each offense.
(3)Â
A separate offense shall be deemed committed upon each day during
or on which a violation occurs or continues.
(4)Â
The Village shall record a notice of violation on the title of the
property.
B.Â
The BPO/ZA shall inform the owner that any such violation is considered
a willful act to increase flood damages and therefore may cause coverage
by a standard flood insurance policy to be suspended.
(1)Â
The BPO/ZA is authorized to issue an order requiring the suspension
of the subject development. The stop-work order shall be in writing,
indicate the reason for the issuance, and shall order the action,
if necessary, to resolve the circumstances requiring the stop-work
order. The stop-work order constitutes a suspension of the permit.
(2)Â
No site development permit shall be permanently suspended or revoked
until a hearing is held by the Board of Appeals. Written notice of
such hearing shall be served on the permittee and shall state:
(3)Â
At such hearing, the permittee shall be given an opportunity to present
evidence on his/her behalf. At the conclusion of the hearing, the
Board of Appeals shall determine whether the permit shall be suspended
or revoked.
C.Â
Nothing herein shall prevent the Village of Sidney from taking such
other lawful action to prevent or remedy any violations. All costs
connected therewith shall accrue to the person or persons responsible.
This chapter repeals and replaces other ordinances adopted by
the Sidney Board of Trustees to fulfill the requirements of the National
Flood Insurance Program, including April 6, 1998. However, this chapter
does not repeal the original resolution or ordinance adopted to achieve
eligibility in the program, nor does this chapter repeal, abrogate,
or impair any existing easements, covenants, or deed restrictions.
Where this chapter and other ordinance easements, covenants or deed
restrictions conflict or overlap, whichever imposes the more stringent
restrictions shall prevail.
