[HISTORY: Adopted by the Town Board of the
Town of Greenport 8-2-1989 by L.L. No. 5-1989.[1], [2] Amendments noted where applicable.]
The Town Board of the Town of Greenport finds
that the potential and/or actual damages from flooding and erosion
may be a problem to the residents of the Town of Greenport 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 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 the 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.
A.
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

The areas of special flood hazard have been
identified by the Federal Emergency Management Agency in a scientific
and engineering report entitled "Flood Insurance Study, Town of Greenport,
New York, Columbia County," dated November 15, 1989, with Flood Insurance
Rate Maps enumerated on Map Index No. 361319 0001-0010, dated November
15, 1989. The above documents are hereby adopted and declared to be
a part of this chapter and are filed at the Town Hall, Town Hall Drive,
Hudson, New York 12534.
A.
This chapter is adopted in response to revisions to
the National Flood Insurance Program, effective October 1, 1986, and
shall supersede all previous laws adopted for the purpose of establishing
and maintaining eligibility for flood insurance.
B.
In their interpretation and application, the provisions
of this chapter shall be held to be minimum requirements, adopted
for the promotion of the public health, safety and welfare. Whenever
the requirements of this chapter are at variance with the requirements
of any other lawfully adopted rules, regulations or ordinances, the
most restrictive or that imposing the higher standards shall govern.
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 be 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 Greenport 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 §§ 69-16 and 69-17 will be declared noncompliant, and notification will be 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 Greenport, 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 Building Inspector 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 § 69-6. 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.
A.
Application stage. The following information is required,
where applicable:

improvements of any resident structure shall:
(1)
Have the lowest floor, including basement or cellar,
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.

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 to
the base flood level.
(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 and exit of floodwaters.
(2)
If the structure is to be floodproofed:

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, with structural components having the capability
of resisting hydrostatic and hydrodynamic loads and 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.

including manufactured homes, shall have the lowest floor, including
basement, elevated 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, § 69-4.) 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 §§ 69-6 and 69-11B, 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.
A.
The Planning Board as established by the Town Board
shall hear and decide requests for variances from the requirements
of this chapter.
B.
The Planning Board shall hear and decide appeals when
it is alleged that there is an error in any requirement, decision
or determination made by the local administrator in the enforcement
or administration of this chapter.
C.
Those aggrieved by the decision of the Planning Board
may appeal such decision to the Supreme Court pursuant to Article
78 of the Civil Practice Law and Rules.
D.
In passing upon such applications, the Planning Board
shall consider all technical evaluations, all relevant factors, standards
specified in other sections of this chapter and:
(1)
The danger that materials may be swept onto other
lands to the injury of others.
(2)
The danger to life and property due to flooding or
erosion damage.
(3)
The susceptibility of the proposed facility and its
contents to flood damage and the effect of such damage on the individual
owner.
(4)
The importance of the services provided by the proposed
facility to the community.
(5)
The necessity to the facility of a waterfront location,
where applicable.
(6)
The availability of alternative locations for the
proposed use which are not subject to flooding or erosion damage.
(7)
The compatibility of the proposed use with existing
and anticipated development.
(8)
The relationship of the proposed use to the Comprehensive
Plan and floodplain management program of that area.
(9)
The safety of access to the property in times of flood
for ordinary and emergency vehicles.
(10)
The costs to local governments and the dangers
associated with conducting search and rescue operations during periods
of flooding.
(11)
The expected heights, velocity, duration, rate
of rise and sediment transport of the floodwaters and the effects
of wave action, if applicable, expected at the site.
(12)
The costs of providing governmental services
during and after flood conditions, including search and rescue operations,
maintenance and repair of public utilities and facilities, such as
sewer, gas, electrical and water systems and streets and bridges.
E.
Upon consideration of the factors of Subsection D and the purposes of this chapter, the Planning Board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
F.
The local administrator shall maintain the records
of all appeal actions, including technical information, and report
any variances to the Federal Emergency Management Agency upon request.
A.
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, provided that the items in § 69-16D(1) through (12) have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
B.
Variances may be issued for the reconstruction, rehabilitation
or restoration of structures and contributing structures listed on
the National Register of Historic Places or the State Inventory of
Historic Places, without regard to the procedures set forth in this
chapter.
C.
Variances may be issued by a community for new construction
and substantial improvements and for other development necessary for
the conduct of a functionally dependent use, provided that:
D.
Variances shall not be issued within any designated
floodway if any increase in flood levels during the base flood discharge
would result.
E.
Variances shall only be issued upon a determination
that the variance is the minimum necessary, considering the flood
hazard, to afford relief.
F.
Variances shall only be issued upon receiving written
justification of:
(1)
A showing of good and sufficient cause;
(2)
A determination that failure to grant the variance
would result in exceptional hardship to the applicant; and
(3)
A determination that the granting of a variance will
not result in increased flood heights, additional threats to public
safety or extraordinary public expense; create nuisances; cause fraud
on or victimization of the public; or conflict with existing local
laws or ordinances.
G.
Any applicant to whom a variance is granted for a
building with the lowest floor below the base flood elevation shall
be given written notice that the cost of flood insurance will be commensurate
with the increased risk.
