[Ord. No. 1053[1] §1, 1-5-2015]
A.
Statutory Authorization. The Legislature of the
State of Missouri has in Section 89.020, RSMo. delegated the responsibility
to local governmental units to adopt floodplain management regulations
designed to protect the health, safety, and general welfare. Therefore,
the City Council of the City of St. John, Missouri ordains as follows.
B.
Findings Of Fact.
1.
Flood losses resulting from periodic inundation. The special flood hazard areas of the City of St. John, 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.
2.
General causes of the flood losses. These flood
losses are caused by the cumulative effect of development in any delineated
floodplain causing increases in flood heights and velocities; and
the occupancy of flood hazard areas by uses vulnerable to floods,
hazardous to others, inadequately elevated, or otherwise unprotected
from flood damages.
C.
Statement Of Purpose. It is the purpose of this Chapter to promote the public health, safety, and general welfare; to minimize those losses described in Section 410.010(B)(1); to establish or maintain the community's eligibility for participation in the National Flood Insurance Program (NFIP) as defined in 44 Code of Federal Regulations (CFR) 59.22(a)(3); and to meet the requirements of 44 CFR 60.3(b) 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.
3.
Protect individuals from buying lands that are unsuited for
the intended development purposes due to the flood hazard.

Editor's Note: This ordinance also repealed former Ch.
410, Flood Hazard Regulations, adopted 7-24-1995 by Ord. No. 519.
[Ord. No. 1053 §1, 1-5-2015]
A.
Lands To Which The Chapter Applies. This Chapter shall apply to all lands within the jurisdiction of the City of St. John identified as unnumbered A Zones, on the Flood Insurance Rate Map (FIRM) dated February 4, 2015, on Map Panel Numbers 29189C0201K, 29189C0202K, 29189C0203K, and 29189C0204K, as amended, and any future revisions thereto. In all areas covered by this Chapter, no development shall be permitted except through the issuance of a floodplain development permit, granted by the City Council or its duly designated representative under such safeguards and restrictions as the City Council or the designated representative may reasonably impose for the promotion and maintenance of the general welfare, health of the inhabitants of the community, and as specifically noted in Section 410.040 below.
B.
Floodplain Administrator. The Public Works Director
is hereby designated as the Floodplain Administrator under this Chapter.
C.
Compliance. No development located within the special
flood hazard areas of this community shall be located, extended, converted,
or structurally altered without full compliance with the terms of
this Chapter and other applicable regulations.
D.
Abrogation And Greater Restrictions. It is not intended
by this Chapter to repeal, abrogate, or impair any existing easements,
covenants, or deed restrictions. However, where this Chapter imposes
greater restrictions, the provisions of this Chapter shall prevail.
All other ordinances inconsistent with this Chapter are hereby repealed
to the extent of the inconsistency only.
E.
Interpretation. In their interpretation and application,
the provisions of this Chapter shall be held to be minimum requirements,
shall be liberally construed in favor of the governing body, and shall
not be deemed a limitation or repeal of any other powers granted by
State statutes.
F.
Warning And Disclaimer Of Liability. The degree
of flood protection required by this Chapter is considered reasonable
for regulatory purposes and is based on engineering and scientific
methods of study. Larger floods may occur on rare occasions or the
flood heights may be increased by man-made or natural causes, such
as ice jams and bridge openings restricted by debris. This Chapter
does not imply that areas outside unnumbered A Zones or land uses
permitted within such areas will be free from flooding or flood damage.
This Chapter shall not create a liability on the part of the City
of St. John, any officer or employee thereof, for any flood damages
that may result from reliance on this Chapter or any administrative
decision lawfully made hereunder.
G.
Severability. If any section, clause, provision,
or portion of this Chapter is adjudged unconstitutional or invalid
by a court of appropriate jurisdiction, the remainder of this Chapter
shall not be affected thereby.
[Ord. No. 1053 §1, 1-5-2015]

with existing state or local health, sanitary, building, safety codes,
regulations or the cost of any alteration of a structure listed on
the National Register of Historic Places, the State Inventory of Historic
Places, or local inventory of historic places upon determination.
B.
Specific Standards.
1.
In all areas of special flood hazard, once base flood elevation data is obtained, as set forth in Section 410.040(A)(2), the following provisions are required:
a.
Residential construction. New construction
or substantial improvement of any residential structure, including
manufactured homes, shall have the lowest floor, including basement,
elevated to one (1) foot above the base flood level.
b.
Non-residential construction. New construction or substantial improvement of any commercial, industrial, or other non-residential structure, including manufactured homes, shall have the lowest floor, including basement, elevated to one (1) foot above the base flood level or, together with attendant utility and sanitary facilities, be floodproofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall certify that the standards of this Subsection are satisfied. Such certification shall be provided to the Floodplain Administrator as required by Section 410.030(C)(7)(c).
c.
Construction of fully enclosed areas subject to flooding. Require, for all new construction and substantial improvements that
fully enclosed areas below lowest floor used solely for parking of
vehicles, building access, or storage in an area other than a basement
and that are subject to flooding shall be designed to automatically
equalize hydrostatic flood forces on exterior walls by allowing for
the entry and exit of floodwaters. Designs for meeting this requirement
must either be certified by a registered professional engineer or
architect or meet or exceed the following minimum criteria:
(1)
A minimum of two (2) openings having a total net
area of not less than one (1) square inch for every square foot of
enclosed area subject to flooding shall be provided; and
(2)
The bottom of all openings shall be no higher than
one (1) foot above grade. Openings may be equipped with screens, louvers,
valves, or other coverings or devices, provided that they permit the
automatic entry and exit of floodwaters.
2.
In all areas of special flood hazard, once floodway data is obtained as set forth in Section 410.040(A)(2), the following provisions shall apply:
a.
The designated floodway shall be based on the standard that
the area chosen for the floodway must be designed to carry the waters
of the base flood, without increasing the water surface elevation
more than one (1) foot at any point; and
b.
The community shall prohibit any encroachments, including fill,
new construction, substantial improvements, and other development
within the designated regulatory floodway unless it has been demonstrated
through hydrologic and hydraulic analyses performed in accordance
with standard engineering practice that the proposed encroachment
would not result in any increase in flood levels within the community
during the occurrence of the base flood discharge.
C.
Manufactured Homes.
1.
All manufactured homes to be placed within special flood hazard
areas shall be required to be installed using methods and practices
that minimize flood damage. For the purposes of this requirement,
manufactured homes must be elevated and anchored to resist flotation,
collapse, or lateral movement. Methods of anchoring may include, but
are not limited to, use of over-the-top or frame ties to ground anchors.
2.
Require manufactured homes that are placed or substantially
improved within unnumbered A Zones on the community's FIRM on
sites outside of a manufactured home park or subdivision; in a new
manufactured home park or subdivision; in an expansion to an existing
manufactured home park or subdivision; or in an existing manufactured
home park or subdivision on which a manufactured home has incurred
substantial damage as the result of a flood, be elevated on a permanent
foundation such that the lowest floor of the manufactured home is
elevated to one (1) foot above the base flood level and be securely
attached to an adequately anchored foundation system to resist flotation,
collapse, and lateral movement.
3.
Require that manufactured homes to be placed or substantially improved on sites in an existing manufactured home park or subdivision within unnumbered A Zones on the community's FIRM, that are not subject to the provisions of Section 410.040(C)(2) of this Chapter, be elevated so that either:
a.
The lowest floor of the manufactured home is one (1) foot above
the base flood level; or
b.
The manufactured home chassis is supported by reinforced piers
or other foundation elements of at least equivalent strength that
are no less than thirty-six (36) inches in height above grade and
be securely attached to an adequately anchored foundation system to
resist flotation, collapse, and lateral movement.
D.
Recreational Vehicles.
1.
Require that recreational vehicles placed on sites within unnumbered
A Zones on the community's FHBM or FIRM either:
a.
Be on the site for fewer than one hundred eighty (180) consecutive
days;
b.
Be fully licensed and ready for highway use. A recreational
vehicle is ready for highway use if it is on its wheels or jacking
system, is attached to the site only by quick-disconnect-type utilities
and security devices, and has no permanently attached additions; or
c.
Meet the permitting, elevation, and the anchoring requirements
for manufactured homes of this Chapter.
[Ord. No. 1053 §1, 1-5-2015]
B.
Responsibility Of The Board Of Adjustment.
1.
Where an application for a floodplain development permit or request for a variance from the floodplain management regulations is denied by the Public Works Director, the applicant may apply for such floodplain development permit or variance directly to the Board of Adjustment, as defined in Section 410.050(A).
2.
The Board of Adjustment shall hear and decide appeals when it is alleged that there is an error in any requirement, decision, or determination made by the Public Works Director in the enforcement or administration of this Chapter; provided, however, that and in addition to the St. John Municipal Code provisions applicable to the Board of Adjustment, said Board shall be bound by Section 410.050(D) and (E) herein.
C.
Further Appeals. Any person aggrieved by the decision
of the Board of Adjustment or any taxpayer may appeal such decision
to the St. Louis County Circuit Court as provided in Section 89.110,
RSMo.
D.
Floodplain Management Variance Criteria. In passing
upon such applications for variances, the Board of Adjustment shall
consider all technical data and evaluations, all relevant factors,
standards specified in other sections of this Chapter, and the following
criteria:
1.
The danger to life and property due to flood damage;
2.
The danger that materials may be swept onto other lands to the
injury of others;
3.
The susceptibility of the proposed facility and its contents
to flood damage and the effect of such damage on the individual owner;
4.
The importance of the services provided by the proposed facility
to the community;
5.
The necessity to the facility of a waterfront location, where
applicable;
6.
The availability of alternative locations, not subject to flood
damage, for the proposed use;
7.
The compatibility of the proposed use with existing and anticipated
development;
8.
The relationship of the proposed use to the Comprehensive Plan
and floodplain management program for that area;
9.
The safety of access to the property in times of flood for ordinary
and emergency vehicles;
10.
The expected heights, velocity, duration, rate of rise and sediment
transport of the floodwaters, if applicable, expected at the site;
and
11.
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, and water systems;
streets; and bridges.
E.
Conditions For Approving Floodplain Management Variances.
1.
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half (1/2) acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, provided that the provisions of Subsection (E)(2) through (6) below have been fully considered. As the lot size increases beyond the one-half (1/2) acre, the technical justification required for issuing the variance increases.
2.
Variances may be issued for the reconstruction, rehabilitation,
or restoration of structures listed on the National Register of Historic
Places, the State Inventory of Historic Places, or local inventory
of historic places upon determination provided that the proposed activity
will not preclude the structure's continued historic designation.
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.
A showing of good and sufficient cause;
b.
A determination that failure to grant the variance would result
in exceptional hardship to the applicant; and
c.
A 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.
6.
The Public Works Director shall notify the applicant in writing
that the issuance of a variance to construct a structure below base
flood level will result in increased premium rates for flood insurance
up to amounts as high as twenty-five dollars ($25.00) for one hundred
dollars ($100.00) of insurance coverage and such construction below
the base flood level increases risks to life and property. Such notification
shall be maintained with the record of all variance actions as required
by this Chapter.
[Ord. No. 1053 §1, 1-5-2015]
A.
Violation of the provisions of this Chapter or failure to comply
with any of its requirements (including violations of conditions and
safeguards established in connection with granting of variances) shall
constitute a misdemeanor. Any person who violates this Chapter or
fails to comply with any of its requirements shall, upon conviction
thereof, be fined not more than one thousand dollars ($1,000.00) and,
in addition, shall pay all costs and expenses involved in the case.
Each day such violation continues shall be considered a separate offense.
B.
Nothing herein contained shall prevent the City of St. John or other
appropriate authority from taking such other lawful action as is necessary
to prevent or remedy any violation.
[Ord. No. 1053 §1, 1-5-2015]
The regulations, restrictions, and boundaries set forth in this
Chapter may from time to time be amended, supplemented, changed, or
appealed to reflect any and all changes in the National Flood Disaster
Protection Act of 1973; provided, however, that no such action may
be taken until after a public hearing in relation thereto, at which
parties of interest and citizens shall have an opportunity to be heard.
Notice of the time and place of such hearing shall be published in
accordance with the Municipal Code of the City of St. John. At least
twenty (20) days shall elapse between the date of the required publication
and the public hearing. A copy of such amendments will be provided
to the Region VII office of the Federal Emergency Management Agency
(FEMA). The regulations of this Chapter are in compliance with the
National Flood Insurance Program (NFIP) regulations.

building permit was issued, provided that the actual start of construction,
repair, reconstruction, rehabilitation, addition placement, or other
improvements was within one hundred eighty (180) days of the permit
date. The actual start means either the first placement of permanent

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.
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would

of this definition, an improvement occurs 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 building. This term includes structures which have incurred
repetitive loss or substantial damage, regardless of the actual repair
work done. The term does not apply to:
Any project for improvement of a building required to comply
with existing health, sanitary, or safety code specifications which
have been identified by the Code Enforcement Official and which are
