15-1-3 BASE FLOOD ELEVATION. This Code's protection standard is the
base flood. The best available base flood elevation data are listed below. Whenever a
party
disagrees with the best available data, the party may fmance the detailed engineering
study needed to replace the existing data with better data and submit it to the Federal
Emergency Management Agency for approval.
[See: NFIP Requirement: 44 CFR 60.3(b).]
(A) The base flood elevation for each of the floodplains delineated as an "A
Zone" on the Flood Insurance Rate Map of the City shall be according to the best data
available from Federal, State or other sources. Should no other data exist, an
engineering
study must be financed to determine base flood elevations.
(B) The base flood elevation for the floodplains of those parts of
unincorporated Jasper County that are within the extraterritorial jurisdiction of the City, or
that may be annexed into the City, shall be as delineated on the loo-year flood profiles
of the
Flood Insurance Study of Jasper County prepared by the Federal Emergency
Management
Agency.

15-1-4 DUTIES OF THE BUILDING OFFICIAL. The Administrator shall
be responsible for the general administration of this Code and ensure that all
development
activities within the floodplains under the jurisdiction of the City meet the requirements of
this
Code. Specifically, the Administrator shall:
(A) Process development permits in accordance with Section 15-1-5;
(B) Ensure that all development in a floodway (or a floodplain with no
delineated floodway) meets the damage prevention requirements of Section 15-1-6.
(C) Ensure that the building protection requirements for all buildings subject
to Section 15-1-7 are met and maintain a record of the "as-built" elevation of the lowest
floor
(including basement) or floodproof certificate;
[See: NFIP Requirements: 44 CFR 60.3(b)(5)(iii) and 59.22(a)(9)(iii).]
(D) Assure that all subdivisions and annexations meet the requirements of
Section 15-1-8;
(E) If a variance is requested, ensure that the requirements of Section 15-1-9
are met and maintain documentation of any variances granted;
(F) Inspect all development projects and take any and all actions outlined in
Section 15-1-11 as necessary to ensure compliance with this Code;
(G) Assure that applicants are aware of and obtain any and all other required
local, state and federal permits;

15-1-5 DEVELOPMENT PERMIT. No person, firm, corporation, or
governmental body, not exempted by state law, shall commence any development in the
floodplain without first obtaining a development permit from the City. The Administrator
shall not issue a development permit if the proposed development does not meet the
requirements of this Code.
(A) Application Documents. The application for development permit shall
be accompanied by:
(1) drawings of the site, drawn to scale showing property line
dimensions;
(2) existing grade elevations and all changes in grade resulting from
excavation or filling;
(3) the location and dimensions of all buildings and additions to
buildings, and
(4) the elevation of the lowest floor (including basements) of all
proposed buildings subject to the requirements of Section 15-1-
7 of this Code.
(B) Elevation Comparisons. Upon receipt of an application for
development permit, the Administrator shall compare the elevation of the site to the
base flood
elevation. Any development located on land that can be shown by survey data to have
been
higher than the base flood elevation as of the date of the site's first Flood Insurance
Rate Map
identification is not in the floodplain and therefore not subject to the requirements of this
Code.
The documentation of the existing ground elevation at the development site and
certification that this ground elevation existed prior to the date of the site's first Flood
Insurance Rate Map identification.
[ED. NOTE: Although survey data may show the development site to be entirely
above the base flood elevation, a Letter of Map Amendment (LOMA) will still be
required to remove the site from the mapped floodplain for insurance requirements.]

15-1-6 PREVENTING INCREASED FLOOD HEIGHTS AND
RESULTING DAMAGES. Within the City's floodplains, the following standards shall
apply:
[NFIP Requirements: 44 CFR 60.3(a)(4)(1), 60.3(c)(10), and 60.3(d)(3).]
(A) Except as provided in Section 15-1-6(B), no development shall be
allowed which, acting in combination with existing and anticipated development, will
cause
any increase in flood heights or velocities or threat to public health and safety. The
following
specific development activiiies shall be considered as meeting this requirement:
(1) Barge fleeting facilities meeting the conditions of
IDOT/DWR Statewide Permit No.3;
(2) Aerial utility crossings meeting the conditions of IDOT/DWR

disposal systems may be permitted providing all manholes or
other above ground openings located below the flood protection
elevation are watertight.
(C) All other activities defined as development shall be designed so as not to
alter flood flows or increase potential flood damages.
[ED. NOTE: This section sets minimum subdivision design review and recording
standards when subdivisions are located within a floodplain. It also provides guidance
for other activities dermed as "development" which may occur in a floodplain. NFIP
Requirement: 44 CFR 60.2(c)
NFIP Requirement: 44 CFR 60.3(b)(3) only applies to subdivisions greater than
five (5) acres or fifty (50) lots.
All new plats recorded must show the location of any floodplains and must be
signed, sealed, and certified by an Illinois Registered Land Surveyor as per the

(5) 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) The applicant's circumstances are unique and do not establish a
pattern inconsistent with the intent of the NFIP; and
(7) All other required local, state and federal permits have
been obtained.
[65 ILCS Sec. 5/11-13-4 and 5/11-13-5 establishes specific
municipal zoning variance criteria.]
(B) Notification of Applicant. The Administrator shall notify an applicant
in writing that a variance from the requirements of the building protection standards of
Section
15-1-7 would lessen the degree of protection to a building will:
(1) Result in increased premium rates for flood insurance
up to Twenty-Five Dollars ($25.00) for One Hundred Dollars
($100.00) of insurance coverage;
(2) Increase the risks to life and property; and
(3) Require that the applicant proceed with knowledge of these risks
and that the applicant acknowledge in writing the
assumption of the risk and liability.
[NOTE: The Standard Flood Insurance Policy permits an
insurance adjustor to not pay for damage that was caused by
something the owner did which increased the hazard to the
property. Section 1316 of the National Flood Insurance Act
authorizes local officials to request denial of flood insurance
for buildings in violation of local floodplain codes.]
( C) Variances to the building protection requirements of Section 15-1-7 of
this Code requested in connection with the reconstruction, repair or alteration of a site or
building included on the National Register of Historic Places or the Illinois Register of
Historic Places may be granted using criteria more permissive than the requirements of
Section 15-1-19 (A)(1-5).
[NOTE: Communities in the NFIP are required to maintain a record of all
variance actions, including justification for their issuance, and report them to FEMA.
FEMA may review variances and suspend a community from the NFIP if the review
"indicates a pattern inconsistent with the objectives of sound floodplain management..."]

15-1-10 DISCLAIMER OF LIABILITY. The degree of protection required by
this Code 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 Code
does not
imply that development either inside or outside of the floodplain will be free from flooding
or
damage. This Code does not create liability on the part of the City or any officer or
employee
thereof for any flood damage that results from reliance on this Code or any
administrative
decision made lawfully thereunder.

15-1-11 PENALTY. 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 Code. Upon due investigation, the Administrator may determine
that
a violation of the minimum standards of this Code exist. The Administrator shall notify the
owner in writing of such violation.
(A) If such owner fails, after ten (10) days' notice, to correct the violation:
(1) The City may make application to the Circuit Court for an
injunction requiring conformance with this Code or make
such other order as the court deems necessary to secure
compliance with this Code.
(2) Any person who violates this Code shall, upon conviction
thereof, be fined not less than Seventy-Five Dollars ($75.00) nor
more than Seven Hundred Fifty Dollars ($750.00).
(3) A separate offense shall be deemed committed upon each day
during or on which a violation occurs or continues.
(B) The City Attorney 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.
(C) Nothing herein shall prevent the City from taking such other lawful
action to prevent or remedy any violations. All costs connected therewith shall accrue to
the
person or persons responsible.

15-1-12 ABROGATION AND GREATER RESTRICTIONS. This Code
repeals and replaces other ordinances adopted by the City Council to fulfill the
requirements of
the National Flood Insurance Program including: However, this Code
does not repeal the original ordinance adopted to achieve eligibility in the Program. Nor
does
this Code repeal, abrogate, or impair any existing easements, covenants or deed
restrictions.
Where this Code and other ordinance easements, covenants or deed restrictions
conflict or
overlap, whichever imposes the more stringent restrictions shall prevail. [See: NFIP
Requirement: 44 CFR 60.2(B).]
