[Ord. No. 1190 Art. 1 §A, 12-8-2011]
The legislature of the State of Missouri has in Section 79.110,
RSMo., delegated the responsibility to local governmental units to
adopt floodplain management regulations designed to protect the health,
safety, and general welfare. Therefore, the Board of Aldermen of the
City of Mound City, Missouri ordains as follows.
[Ord. No. 1190 Art. 1 §B, 12-8-2011]
A. Flood Losses Resulting From Periodic Inundation. The special
flood hazard areas of the City of Mound City, 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 of flood hazard areas by uses vulnerable to floods, hazardous
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 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 Holt County dated January 6, 1988,
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.
[Ord. No. 1190 Art. 1 §C, 12-8-2011]
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 Code of Federal Regulations (CFR) 59.22(a)(3); and to meet the requirements of 44 CFR 60.3(c) 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.
