AN ORDINANCE OF THE CITY OF MERIDIAN AMENDING TITLE 10
CHAPTER 6 FLOOD DAMAGE PREVENTION OF THE MERIDIAN CITY CODE
PROVIDING FOR GENERAL PROVISIONS; AND PROVIDING AN EFFECTIVE
DATE.
WHEREAS, the National Flood Insurance Program is a federal program which
enables property owners in participating communities to purchase insurance as protection
against flood losses in exchange for the adoption of community floodplain management
regulations that reduce future flood damages;
WHEREAS, the City of Meridian is a participating community in the National
Flood Insurance Program; and
WHEREAS, the regulatory standards set forth in this ordinance meet or exceed the
regulations of 44 C.F.R. Sections 59-65 and Parts 70 and 73, regarding floodplain
management, for the protection of public health, safety and welfare; and
WHEREAS, the policies expressed herein are designed to protect public health,
safety and welfare by minimizing public and private losses due to flood conditions;
NOW, THEREFORE, BE IT ORDAINED BY THE MAYOR AND CITY COUNCIL
OF THE CITY OF MERIDIAN, ADA COUNTY, IDAHO:
SECTION 1: That Title 10 Chapter 6 Flood Damage Prevention of the Meridian
City Code is hereby amended as follows:
CHAPTER 6
FLOOD DAMAGE PREVENTION
10-6-1: FINDINGS OF FACT, PURPOSE AND OBJECTIVES:
A. Findings Of Fact:
1. The . Special F'lood Hazard Areas of the City are subject to periodic
inundation which caiz results in loss of life, a~A-property dama~e, hazard to health, and
safety~~, disruption of commerce and governmental services, extraordinary public
FLOOD DAMAGE PREVENTION AMENDMENT ORDINANCE - PAGE 1 OF 19
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. These flood losses are ag rag vateds~ by the cumulative efFect of obstructions in
~,.~°„°,.:~' ~'~~a'~°~~raSpecial Flood Hazard Areas which increase flood
elevations. Development that isn~~*~s-~ ra~~~~~r "cs-i "cr rdv'-i°c~i-ii~csa~
, . inadequately flood=proofed,
elevated, or otherwise protected from flood damage also contributes to~e flood losses.
B. Statement Of Purpose: It is the purpose of this Chapter to promote the public health,
safety, and general welfare, and to minimize public and private losses due to flood
conditions in specific areas by provisions designed:
1. To protect human life and health;
2. To minimize expenditure of public money and costly flood control projects;
3. To minimize the need for rescue and relief efforts associated with flooding and
generally undertaken at the expense of the general public;
4. To minimize prolonged business interruptions;
5. To ~~~minimize damage to public facilities and utilities such as water and gas
mains, electric, telephone and sewer lines, streets, and bridges located in areas of
special flood hazard;
6. To help ~~emaintain a stable tax base by providing for the sound use and
development of areas of special flood hazard so as to minimize future flood blight
areas;
7. To ensure that infonnation regardi~ the location of Special Flood Hazard_ Areas is
read.ily available to~otential property buyers and other interested peopl_e~~
, ; and
8. To ensure that those who occupy Special Flood Hazard Areas+'~° °r°°° ^~ °~°~:°'
#~c~~~ assume responsibility for their actions.
C. Methods Of Reducing Flood Losses: In order to accomplish its purposes, this Chapter
includes methods and provisions for managin d~pment in flood prone areas to
insure that:
1. Stiuctures are designed and built to acceptable standards to be protected fi-om
