[Ord. No. 678 §1(Art. 1, A
— B), 1-10-2005]
A. The
legislature of the State of Missouri has in Chapter 89 Section 89.020,
RSMo., delegated the responsibility to local government units to adopt
floodplain management regulations designed to protect the health,
safety and general welfare. Therefore, the Board of Aldermen of the
City of Oakland ordains as follows.
B. Findings Of Fact.
1. Flood losses resulting from periodic inundation. The special flood hazard areas of the City of Oakland, Missouri,
are subject to periodic inundation which results in loss of life,
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 by
the occupancy in flood hazard areas by uses vulnerable to floods,
hazardous to others, inadequately elevated, or otherwise unprotected
from flood damages.
3. 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.
a. 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 dated August
23, 2000, as amended, and any future revisions thereto.
b. 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.
c. Computation of a floodway required to convey this flood without increasing
flood heights more than one (1) foot at any point.
d. Delineation of floodway encroachment lines within which no development
is permitted that would cause any increase in flood height.
e. Delineation of floodway fringe, i.e., that area outside the floodway
encroachment lines but still subject to inundation by the base flood.
[Ord. No. 678 §1(Art. 1, C), 1-10-2005]
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
415.010(B); 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(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.
