The Town Board of the Town of Babylon finds that the potential
and/or actual damages from flooding and erosion may be a problem to
the residents of the Town of Babylon and that such damages may include
destruction or loss of private and public housing, damage to public
facilities, both publicly and private 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;
and
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, 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; and
H.
Ensure that those who occupy the areas of special flood hazard assume
responsibility for their actions.
A.
Unless specifically defined below, words or phrases used in this
chapter shall be interpreted so as to give them the meaning they have
in common usage and to give this chapter its most reasonable application.

As used in this chapter, the following terms shall have the meanings
indicated:
A request for a review of the local administrator's interpretation
of any provision of this chapter or a request for a variance.
A designated AO, AH or VO Zone on a community's Flood Insurance
Rate Map (FIRM) with a one-percent-or-greater annual chance of flooding
to an average annual depth of one to three feet where a clearly defined
channel does not exist, where the path of flooding is unpredictable
and where velocity flow may be evident. Such flooding is characterized
by ponding or sheet flow.
The land in the floodplain within a community subject to
a one-percent-or-greater chance of flooding in any given year. This
area may be designated as Zone A, AE, AH, AO, A1-A30, A99, V, VO,
VE, or V1-V30. It is also commonly referred to as the base floodplain
or one-hundred-year floodplain. For purposes of this chapter, the
term "special flood hazard area (SFHA)" is synonymous in meaning with
the phrase "area of special flood hazard."
The flood having a one-percent chance of being equaled or
exceeded in any given year.
That portion of a building having its floor subgrade (below
ground level) on all sides.
A wall that is not part of the structural support of the
building and is intended through its design and construction to collapse
under specific lateral loading forces without causing damage to the
elevated portion of the building or the supporting foundation system.
See "structure."
Has the same meaning as "basement."
An area of special flood hazard extending from offshore to
the inland limit of a primary frontal dune along an open coast and
any other area subject to high velocity wave action from storms or
seismic sources. The area is designated on a FIRM as Zone V1-V30,
VE, VO or V.
An enclosed area beneath the lowest elevated floor, 18 inches
or more in height, which is used to serve the underside of the lowest
elevated floor. The elevation of the floor of this enclosed area,
which may be of soil, gravel, concrete or other material, must be
equal to or above the lowest adjacent exterior grade. The enclosed
crawl space area shall be properly vented to allow for the equalization
of hydrostatic forces which would be experienced during periods of
flooding.
Any man-made change to improved or unimproved real estate,
including but not limited to buildings or other structures, mining,
dredging, filling, paving, excavation or drilling operations or storage
of equipment or materials.
A nonbasement building:
Built, in the case of a building in Zones A1-A30, AE, A A99,
AO, AH, B, C, X or D, to have the top of the elevated floor, or in
the case of a building in Zones V1-30, VE, or V, to have the bottom
of the lowest horizontal structure member of the elevated floor, elevated
above the ground level by means of pilings, columns (posts and piers),
or shear walls parallel to the flow of water; and
Adequately anchored so as not to impair the structural integrity
of the building during a flood of up to the magnitude of the base
flood.
In the case of Zones A1-A30, AE, A, A99, AO, AH, B, C, X, or
D, "elevated building" also includes a building elevated by means
of fill or solid foundation perimeter walls with openings sufficient
to facilitate the unimpeded movement of floodwaters.
In the case of Zones V1-V30, VE, or V, "elevated building" also
includes a building otherwise meeting the definition of "elevated
building," even though the lower area is enclosed by means of breakaway
walls that meet the federal standards.
The federal agency that administers the National Flood Insurance
Program.
The collapse or subsidence of land along the shore of a lake
or other body of water as a result of erosion or undermining caused
by waves or currents of water exceeding anticipated cyclical levels
or suddenly caused by unusually high water level in a natural body
of water, accompanied by a severe storm, or by an unanticipated force
of nature, such as a flash flood or an abnormal tidal surge, or by
some similarly unusual and unforeseeable event which results in flooding
as defined in (1)(a) above.
An official map of the community published by the Federal
Emergency Management Agency as part of a riverine community's Flood
Insurance Study. The FBFM delineates a regulatory floodway along watercourses
studied in detail in the Flood Insurance Study.
An examination, evaluation and determination of the flood
hazards and, if appropriate, corresponding water surface elevations,
or an examination, evaluation and determination of flood-related erosion
hazards.
An official map of a community, issued by the Federal Emergency
Management Agency, where the boundaries of the areas of special flood
hazard have been designated as Zone A but no flood elevations are
provided.

damage to real estate or improved real property, water and sanitary
facilities, structures and their contents.
Has the same meaning as "regulatory floodway.”F
A use which cannot perform its intended purpose unless it
is located or carried out in close proximity to water, such as a docking
or port facility necessary for the loading and unloading of cargo
or passengers, shipbuilding, and ship repair facilities. The term
does not include long-term storage, manufacturing, sales, or service
facilities.
The highest natural elevation of the ground surface, prior
to construction, next to the proposed walls of a structure.
Any structure that is:
Listed individually in the National Register of Historic Places
(a listing maintained by the Department of the Interior) or preliminarily

by the Secretary of the Interior; or
Individually listed on a local inventory of historic places
in communities with historic preservation programs that have been
certified either:
The person appointed by the community to administer and implement
this chapter by granting or denying development permits in accordance
with its provisions. This person is often the Building Inspector,
Code Enforcement Officer, or employee of an engineering department.
lowest floor of the lowest enclosed area (including basement
or cellar). An unfinished or flood-resistant enclosure, usable solely
for parking of vehicles, building access, or storage in an area other
than a basement area is not considered a building's lowest floor,
provided that such enclosure is not built so as to render the structure
in violation of the applicable nonelevation design requirements of
this chapter.
A structure, transportable in one or more sections, which
is built on a permanent chassis and designed to be used with or without
a permanent foundation when connected to the required utilities. The
term does not include a recreational vehicle.

adopted by the community and includes any subsequent improvements
to such structure.
Has the same meaning as "base flood."
A contiguous or nearly contiguous mound or ridge of sand
with relatively steep seaward and landward slopes immediately landward
and adjacent to the beach and subject to erosion and overtopping from
high tides and waves during major coastal storms. The inland limit
of the primary frontal dune occurs at the point where there is a distinct
change from a relatively steep slope to a relatively mild slope.
At least 51% of the actual cash value of the structure, excluding
land value, is above ground.
A vehicle which is:
Built on a single chassis;
Four hundred square feet or less when measured at the largest
horizontal projections;
Designed to be self-propelled or permanently towable by a light
duty truck; and
Not designed primarily for use as a permanent dwelling but as
temporary living quarters for recreational, camping, travel or seasonal
use.
The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height as determined by the Federal Emergency Management Agency in a Flood Insurance Study or by other agencies as provided in § 125-14B of this chapter.
Naturally occurring accumulations of sand in ridges or mounds
landward of the beach.
The date of permit issuance for new construction and substantial
improvements to existing structures, provided that actual start of
construction, repair, reconstruction, rehabilitation, addition placement,
or other improvement is within 180 days after the date of issuance.
The actual start of construction means the first placement of permanent
construction of a building (including a manufactured home) on a site,
such as the pouring of a slab or footings, installation of pilings

land preparation (such as clearing, excavation. grading, or filling),
or the installation of streets or walkways, or excavation for a basement,
footings, piers or foundations, or the erection of temporary forms,
or the installation of accessory buildings, such as garages or sheds
not occupied as dwelling units or not part of the main building. For
a substantial improvement, the actual "start of construction means
the first alteration of any wall, ceiling, floor, or other structural
part of a building, whether or not that alteration affects the external
dimensions of the building.
A walled and roofed building, including a gas or liquid storage
tank, that is principally above ground, as well as a manufactured
home.
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would
equal or exceed 50% of the market value of the structure before the
damage occurred.
Any reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceeds 50% of the market
value of the structure before the "start of construction" of the improvement.
The term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions;
or
Any alteration of an historic structure, provided that the alterations
will not preclude the structure's continued designation as an "historic
structure."
A grant of relief from the requirements of this chapter which
permits construction or use in a manner that would otherwise be prohibited
by this chapter.
