The Legislature of the State of Connecticut
has, in § 7-194 of its General Statutes, as amended, delegated
the responsibility to local governmental units to adopt regulations
designed to promote the public health, safety, and general welfare
of its citizenry.
It is the purpose of this chapter to promote
the public health, safety and general welfare within the City and
to minimize public and private losses due to flood conditions in the
floodway and flood-fringe areas in the City and to protect the aquifer
within said areas by provisions designed to:
A. Protect human life and health;
B. Minimize expenditures of public money for costly flood-control
projects;
C. Minimize the need for rescue and relief efforts associated
with flooding and generally undertaken at the expense of the general
public;
D. Minimize prolonged business interruptions;
E. 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 hazards;
F. Help maintain 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;
G. Ensure that potential buyers are notified that property
is in an area of special flood hazard; and
H. Ensure that those who occupy the areas of special
flood hazard assume responsibility for their actions.
In order to accomplish its purposes, this chapter
includes methods and provisions for:
A. Restricting or prohibiting uses which are dangerous
to health, safety, and property due to water and erosion hazards,
or which result in damaging increases in erosion or in flood heights
or velocities;
B. Requiring that uses vulnerable to floods, including
facilities which serve such uses, be protected against flood damage
at the time of initial construction;
C. Controlling the alteration of natural floodplains,
stream channels, and natural protective barriers, which help accommodate
or channel floodwaters;
D. Controlling filling, grading, dredging, and other
development which may increase flood damage;
E. Preventing or regulating the construction of flood
barriers which will unnaturally divert floodwaters or which may increase
flood hazards in other areas;
F. Protecting the aquifer for use as a public water supply,
by limiting the amount of impervious surface within the floodplain
area, and reducing the effect of de-icing salts, chemicals and other
pollutants.

stringent restrictions shall prevail.
In the interpretation and application of this
chapter, all provisions shall be:
A. Considered as minimum requirements;
B. Liberally construed in favor of the governing body;
C. Deemed neither to limit nor repeal any other powers
granted under the state statutes.
The degree of flood protection required by this
chapter is considered reasonable for regulatory purposes and is based
on scientific and engineering considerations. Larger floods can and
will occur on rare occasions. Flood heights may be increased by man-made
or natural causes. This chapter does not imply that land outside the
areas of special flood hazards or uses permitted within such areas
will be free from flooding or flood damages. This chapter shall not
create liability on the part of the City of Meriden, any officer or
employee thereof, or the Federal Insurance Administration, for any
flood damages that result from reliance on this chapter or any administrative
decision lawfully made thereunder.
A development permit shall be obtained before construction or development begins within any area of special flood hazard established in §
110-7. Application for a development permit shall be made on forms furnished by the administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions, and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing.

of such notification to the Federal Emergency Management Agency (FEMA).
(2) Require that flows equal to or greater than those
presently encountered be maintained. Changes to existing flood-carrying
capacities shall not adversely affect upstream or downstream floodways
or watercourses.
(3) Require that flood stages and water surface heights
be substantially maintained at their present elevations.
E. Interpretation of FIRM boundaries: make interpretations where needed as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions). The person contesting the location of the boundary shall be given an opportunity to appeal the interpretation as provided in §
110-20A.
F. Assure that subdivision proposals and proposals for
other developments, including their utilities and drainage, are located
and designed to be consistent with the need to minimize flood damage.
G. Require that all subdivision proposals and other proposed
new developments and substantial improvements include base flood data.
H. Require new water and sewer systems (including on-site
systems) to be located and designed to avoid impairment and to minimize
infiltration into and exfiltration out of the system.
I. Require anchoring to prevent flotation and lateral
movement of any type of structural development.
J. Assure, through inspection of permitted activities,
that compliance with this chapter is maintained.
K. Grant permits for regulated use activities as defined in §
