[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]

SPECIAL FLOOD HAZARD AREA
See "area of special flood hazard."
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.

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.
