[R.O. 2016 § 415.010; Ord. No. 175-98 § 1, 1-13-1998]
The legislature of the State of Missouri
has in Chapter 89, RSMo., delegated the responsibility to local governmental
units to adopt regulations designed to protect the health, safety
and general welfare. Therefore, the City Council of the City of Park
Hills, Missouri, ordains as follows.
[R.O. 2016 § 415.020; Ord. No. 175-98 § 1, 1-13-1998; Ord. No. 632-05 §§ 1
— 2, 7-12-2005; Ord. No. 958-11 § 1, 5-10-2011]
A. Flood Losses Resulting From Periodic Inundation.
The special flood hazard areas of the City of Park Hills, Missouri,
are subject to inundation which results in loss of life and property,
health and safety hazards, disruption 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. General Causes Of The Flood Losses. These
flood losses are caused by:
1.
The cumulative effect of development
in any delineated floodplain causing increases in flood heights and
velocities; and
2.
The occupancy in flood hazard areas
by uses vulnerable to floods, hazards to others, inadequately elevated,
or otherwise unprotected from flood damages.
C. Methods Used To Analyze Flood Hazards.
The Flood Insurance Study (FIS) that is the basis of this Chapter
uses a standard engineering method of analyzing flood hazards which
consist of a series of interrelated steps.
1.
Selection of a base flood that is
based upon engineering calculations which permit a consideration of
such flood factors as its expected frequency of occurrence, the area
inundated, and the depth of inundation. The base flood selected for
this Chapter is representative of large floods which are characteristic
of what can be expected to occur on the particular streams subject
to this Chapter. It is in the general order of a flood which could
be expected to have a one percent (1%) chance of occurrence in any
one (1) year as delineated on the Federal Insurance Administrator's
FIS, and illustrative materials for St. Francois County with an effective
date of June 16, 2011, as amended, and any future revisions thereto.
2.
Calculation of water surface profiles
are based on a standard hydraulic engineering analysis of the capacity
of the stream channel and overbank areas to convey the regulatory
flood.
3.
Computation of a floodway required
to convey this flood without increasing flood heights more than one
(1) foot at any point.
4.
Delineation of floodway encroachment
lines within which no development is permitted that would cause any
increase in flood height.
5.
Delineation of flood fringe, i.e.,
that area outside the floodway encroachment lines, but still subject
to inundation by the base flood.
[R.O. 2016 § 415.030; Ord. No. 175-98 § 1, 1-13-1998]
A. It is the purpose of this Chapter to promote the public health, safety and general welfare; to minimize those losses described in Article
I, Section
415.020(A); to establish or maintain the community's eligibility for participation in the National Flood Insurance Program (NFIP) as defined in 44 CFR 59.22(a)(3); and to meet the requirements of 44 CFR 60.3(d) by applying the provisions of this Chapter to:
1.
Restrict or prohibit uses that are
dangerous to health, safety, or property in times of flooding or cause
undue increases in flood heights or velocities;
2.
Require uses vulnerable to floods,
including public facilities that serve such uses, be provided with
flood protection at the time of initial construction; and
3.
Protect individuals from buying lands
that are unsuited for the intended development purposes due to the
flood hazard.
[R.O. 2016 § 415.040; Ord. No. 175-98 § 1, 1-13-1998]

of the applicable floodproofing design requirements of this Chapter.
MANUFACTURED HOME

is built on a permanent chassis and is designed for use with or without
a permanent foundation when attached to the required utilities. The
term "manufactured home" does not include a "recreational vehicle."

for which the start of construction commenced on or after the effective
date of an initial FIRM or after December 31, 1974, whichever is later,

the start of construction commenced on or after the effective date
of a floodplain management regulation adopted by a community and includes
any subsequent improvements to such structures.

include provisions for operating costs and allowances.
SPECIAL HAZARD AREA
An area having special flood hazards and shown on a FHBM,
FIRM or FBFM as Zones (unnumbered or numbered) A and AE.
START OF CONSTRUCTION
Includes substantial improvements, 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 one hundred eighty (180) days of the permit
date. The "actual start" means 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, the installation
of streets and/or walkways, excavation for a basement, footings, piers,
foundations, the erection of temporary forms, nor installation on
the property of accessory structures, such as garages or sheds not
occupied as dwelling units or not 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.
STATE COORDINATING AGENCY

by the Governor of the State or by State Statute at the request of
the Administrator to assist in the implementation of the National
Flood Insurance Program (NFIP) in that State.
STRUCTURE
For floodplain management purposes, a walled and roofed building,
including a gas or liquid storage tank, that is principally above
ground, as well as a manufactured home. "Structure" for insurance
purposes means a walled and roofed building, other than a gas or liquid
storage tank, that is principally above ground and affixed to a permanent
site, as well as a manufactured home on a permanent foundation. For
the latter purpose, the term includes a building while in the course
of construction, alteration or repair, but does not include building
materials or supplies intended for use in such construction, alteration
or repair, unless such materials or supplies are within an enclosed
building on the premises.
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 other improvements
of a structure, the cost of which equals or exceeds fifty percent
(50%) of the market value of the structure before "start of construction"
of the improvement. This term includes structures which have incurred
"substantial damage," regardless of the actual repair work performed.
The term does not, however, include either:
1.
Any project for improvement of a
structure to correct existing violations of State or local health,
sanitary, or safety code specifications that have been identified
by the local Code Enforcement Official and which are the minimum necessary
to assure safe living conditions; or
2.
Any alteration of a "historic structure,"
provided that the alteration will not preclude the structure's continued
designation as a "historic structure."
VARIANCE
A grant of relief to a person from the terms of a floodplain
management regulation. Flood insurance requirements remain in place
for any varied use or structure and cannot be varied by the community.
VIOLATION
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 elevation certificate,
other certifications, or other evidence of compliance required by
this Chapter is presumed to be in violation until such time as that
documentation is provided.
WATER SURFACE ELEVATION
The height, in relation to the National Geodetic Vertical
Datum (NGVD) of 1929 (or other datum where specified) of floods of
various magnitudes and frequencies in the floodplain.
