The Town Board of the Town of Cazenovia finds that the potential and/or
actual damages from flooding and erosion may be a problem to the residents
of the Town of Cazenovia and that such damages may include destruction or
loss of private and public housing, damage to public facilities, both publicly
and privately owned, and injury to and loss of human life. In order to minimize
the threat of such damages and to achieve the purposes and objectives hereinafter
set forth, this chapter is adopted.
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 to:
A. Regulate uses which are dangerous to health, safety and
property due to water or erosion hazards or which result in damaging increases
in erosion or in flood heights or velocities.
B. Require that uses vulnerable to floods, including facilities
which serve such uses, be protected against flood damage at the time of initial
construction.
C. Control the alteration of natural floodplains, stream
channels and natural protective barriers which are involved in the accommodation
of floodwaters.
D. Control filling, grading, dredging and other development
which may increase erosion or flood damages.
E. Regulate the construction of flood barriers which will
unnaturally divert floodwaters or which may increase flood hazards to other
lands.
F. Qualify for and maintain participation in the National
Flood Insurance Program.
The objectives of this chapter are to:
A. Protect human life and health.
B. Minimize expenditure 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 hazard.
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. Provide that developers are notified that property is
in an area of special flood hazard.
H. Ensure that those who occupy the areas of special flood
hazard assume responsibility for their actions.
Unless specifically defined below, words or phrases used in this chapter
shall be interpreted so as to give them the meanings they have in common usage
and to give this chapter its most reasonable application.

The areas of special flood hazard are identified by the Federal Emergency
Management Agency in a scientific and engineering report titled "Flood Insurance
Study of the Town of Cazenovia, of Madison County, New York," dated June 19,
1985, which report, with accompanying Flood Insurance Rate Maps and Flood
Boundary and Floodway Maps, is hereby adopted and declared to be a part of
this chapter. The Flood Insurance Study and maps are on file at the Cazenovia
Town Office Building, 7 Albany Street, Cazenovia, New York. (Community Panel
Numbers: 361290 0001-0020.)
No structure shall hereafter be constructed, located, extended, converted or altered and no land shall be excavated or filled without full compliance with the terms of this chapter and any other applicable regulations. Any infraction of the provisions of this chapter by failure to comply with any of its requirements, including infractions of conditions and safeguards established in connection with conditions of the permit, shall constitute a violation. Any person who violates this chapter or fails to comply with any of its requirements shall, upon conviction thereof, be fined no more than $250 or imprisoned for not more than 15 days, or both. Each day of noncompliance shall be considered a separate offense. Nothing herein contained shall prevent the Town of Cazenovia from taking such other lawful action as necessary to prevent or remedy an infraction. Any structure found not compliant with the requirements of this chapter for which the developer and/or owner has not applied for and received an approved variance under §§
93-16 and
93-17 will be declared noncompliant and notification sent to the Federal Emergency Management Agency.
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 hazard 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 Town of Cazenovia, any officer
or employee thereof or the Federal Emergency Management Agency for any flood
damages that result from reliance on this chapter or any administrative decision
lawfully made thereunder.
The Zoning Board of Appeals is hereby appointed local administrator
to administer and implement this chapter by granting or denying development
permit applications in accordance with its provisions.
A development permit shall be obtained before the start of construction or any other development within the area of special flood hazard as established in §
93-6. Application for a development permit shall be made on forms furnished by the local administrator and may include but not be limited to plans, in duplicate, drawn to scale and 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.

elevated to or above the base flood elevation.
(2) Have fully enclosed areas below the lowest floor that
are subject to flooding 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 licensed
professional engineer or architect or meet or exceed the following minimum
criteria:
(a) A minimum of two openings having a total net area of
not less than one square inch for every square foot of enclosed area subject
to flooding shall be provided.
(b) The bottom of all such openings shall be no higher than
one foot above the lowest adjacent finished grade.
(c) Openings may be equipped with louvers, valves, screens
or other coverings or devices, provided that they permit the automatic entry

B. Nonresidential construction. New construction and substantial
improvements of any commercial, industrial or other nonresidential structure,
together with attendant utility and sanitary facilities, shall either have
the lowest floor, including basement or cellar, elevated to or above the base
flood elevation or be floodproofed so that the structure is watertight below
the base flood level with walls substantially impermeable to the passage of
water. All structural components located below the base flood level must be
capable of resisting hydrostatic and hydrodynamic loads and the effects of
buoyancy.
(1) If the structure is to be elevated, fully enclosed areas
below the base flood elevation shall be designed to automatically (without
human intervention) allow for the entry and exit of floodwaters for the purpose
of equalizing hydrostatic flood forces on exterior walls. Designs for meeting
this requirement must either be certified by a licensed professional engineer
or a licensed architect or meet the following criteria:
(a) A minimum of two openings having a total net area of
not less than one square inch for every square foot of enclosed area subject
to flooding shall be provided.
(b) The bottom of all such openings shall be no higher than
one foot above the lowest adjacent finished grade.
(c) Openings may be equipped with louvers, valves, screens
or other coverings or devices, provided that they permit the automatic entry

(a) A licensed professional engineer or architect shall develop
and/or review structural design, specifications and plans for the construction
and shall certify that the design and methods of construction are in accordance
with accepted standards of practice to make the structure watertight, with
walls substantially impermeable to the passage of water and with structural
components having the capability of resisting hydrostatic and hydrodynamic
loads and the effects of buoyancy.
(b) A licensed professional engineer or licensed land surveyor
shall certify the specific elevation (in relation to mean sea level) to which
the structure is floodproofed.
(3) The local administrator shall maintain on record a copy
of all such certificates noted in this section.
C. Construction standards for areas of special flood hazard without base flood elevations. New construction or substantial improvements of structures, including manufactured homes, shall have the lowest floor, including basement, elevated to or above the base flood elevation as may be determined in §
93-12B or two feet above the highest adjacent grade where no elevation data is available.
(1) New construction or substantial improvements of structures,
including manufactured homes, shall have the lowest floor (including basement)
elevated to at least two feet above the highest adjacent grade next to the
proposed foundation of the structure.
(2) Fully enclosed areas below the lowest floor that are
subject to flooding shall be designed to automatically (without human intervention)
allow for the entry and exit of floodwaters for the purpose of equalizing
hydrostatic flood forces on exterior walls. Designs for meeting this requirement
must either be certified by a licensed professional engineer or a licensed
architect or meet the following criteria:
(a) A minimum of two openings having a total net area of
not less than one square inch for every square foot of enclosed area subject
to flooding shall be provided.
(b) The bottom of all such openings shall be no higher than
one foot above the lowest adjacent finished grade.
(c) Openings may be equipped with louvers, valves, screens
or other coverings or devices, provided that they permit the automatic entry
and exit of floodwaters.
Located within areas of special flood hazard are areas designated as floodways (see definition, §
93-4). The floodway is an extremely hazardous area due to high-velocity floodwaters carrying debris and posing additional threats from potential erosion forces. When floodway data is available for a particular site as provided by §§
93-6 and
93-12B, all encroachments, including fill, new construction, substantial improvements and other development, are prohibited within the limits of the floodway unless a technical evaluation demonstrates that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
