Ch. 80, Flood Damage Prevention, adopted 11-8-1995 by L.L. No. 4-1995,
as amended.
The Town Board of the Town of Esopus finds that the potential
and/or actual damages from flooding and erosion may be a problem to
the residents of the Town of Esopus 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, 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 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; and,
H.
Ensure
that those who occupy the areas of special flood hazard assume responsibility
for their actions.
A.
Word
usage. 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.
See "structure."
Has the same meaning as "basement."
An enclosed area beneath the lowest elevated floor, 18 inches
or more in height, which is used to service 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-V30,
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 the 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.

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.

Any land area susceptible to being inundated by water from
any source (see definition of "flooding").
Any combination of structural and nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood
damage to real estate or improved real property, water and sanitary
facilities, structures and their contents.
Has the same meaning as "regulatory floodway."
A use which cannot perform its intended purpose unless it
is located or carried out in close proximity to water, such as a docking

with its provisions.
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

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
or construction of columns. Permanent construction does not include
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

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 alteration
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.
This chapter shall apply to all areas of special flood hazard
within the jurisdiction of the Town of Esopus, Ulster County.
A.
The areas of special flood hazard for the Town of Esopus, Community
Number 360855, are identified and defined on the following documents
prepared by the Federal Emergency Management Agency:
(1)
Flood Insurance Rate Map Panel Numbers 36111C0470E, 36111C0490E,
36111C0605E, 36111C0610E, 36111C0615E, 36111C0620E, 36111C0630E, 36111C0640E
whose effective date is September 25, 2009, and any subsequent revisions
to these map panels that do not affect areas under our community's
jurisdiction.
(2)
A scientific and engineering report entitled "Flood Insurance Study,
Ulster County, New York, All Jurisdiction" dated September 25, 2009.
B.
The above documents are hereby adopted and declared to be a part
of this chapter. The Flood Insurance Study and/or maps are on file
at Town of Esopus Building Department, 284 Broadway, Port Ewen, NY
12466.
A.
This
chapter includes all revisions to the National Flood Insurance Program
through October 27, 1997 and shall supersede all previous laws adopted
for the purpose of flood damage prevention.
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, ordinances, or local laws, the
most restrictive, or that imposing the higher standards, shall govern.
The invalidity of any section or provision of this chapter shall
not invalidate any other section or provision thereof.
No structure in an area of special flood hazard 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 Esopus 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 §§ 80-20 and 80-21 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 area 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 Town of Esopus, 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 floodplain
development permits in accordance with its provisions.
A.
Purpose. A floodplain development permit is hereby established for all construction and other development to be undertaken in areas of special flood hazard in this community for the purpose of protecting its citizens from increased flood hazards and insuring that new development is constructed in a manner that minimizes its exposure to flooding. It shall be unlawful to undertake any development in an area of special flood hazard, as shown on the Flood Insurance Rate Map enumerated in § 80-6, without a valid floodplain development permit. Application for a 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.
B.
Fees. All applications for a floodplain development permit shall
be accompanied by an application fee of $100. In addition, the applicant
shall be responsible for reimbursing the Town of Esopus for any additional
costs necessary for review, inspection and approval of this project.
The local administrator may require a deposit of no more than $500
to cover these additional costs.
The applicant shall provide the following information as appropriate.
Additional information may be required on the permit application form.
A.
The proposed elevation, in relation to mean sea level, of the lowest
floor (including basement or cellar) of any new or substantially improved
structure to be located in Zones A1-A30, AE or AH, or Zone A if base
flood elevation data are available. Upon completion of the lowest
floor, the permitee shall submit to the local administrator the as-built
elevation, certified by a licensed professional engineer or surveyor.
B.
The proposed elevation, in relation to mean sea level, to which any
new or substantially improved nonresidential structure will be floodproofed.
Upon completion of the floodproofed portion of the structure, the
permitee shall submit to the local administrator the as-built floodproofed
elevation, certified by a professional engineer or surveyor.
C.
A certificate from a licensed professional engineer or architect that any utility floodproofing will meet the criteria in § 80-16C, Utilities.
[Amended 11-19-2009 by L.L. No. 13-2009]
D.
A certificate from a licensed professional engineer or architect that any nonresidential floodproofed structure will meet the floodproofing criteria in § 80-18, Construction standards for nonresidential structures.
E.
A description of the extent to which any watercourse will be altered or relocated as a result of proposed development. Computations by a licensed professional engineer must be submitted that demonstrate that the altered or relocated segment will provide equal or greater conveyance than the original stream segment. The applicant must submit any maps, computations or other material required by the Federal Emergency Management Agency (FEMA) to revise the documents enumerated in § 80-6, when notified by the local administrator, and must pay any fees or other costs assessed by FEMA for this purpose. The applicant must also provide assurances that the conveyance capacity of the altered or relocated stream segment will be maintained.
F.
A technical analysis, by a licensed professional engineer, if required
by the local administrator, which shows whether proposed development
to be located in an area of special flood hazard may result in physical
damage to any other property.
G.
In Zone A, when no base flood elevation data are available from other
sources, base flood elevation data shall be provided by the permit
applicant for subdivision proposals and other proposed developments
(including proposals for manufactured home and recreational vehicle
parks and subdivisions) that are greater than either 50 lots or five
acres.
Duties of the local administrator shall include, but not be
limited to the following:
A.
Permit application review. The local administrator shall conduct
the following permit application review before issuing a floodplain
development permit:
(1)
Review all applications for completeness, particularly with the requirements of § 80-13, Application for permit, and for compliance with the provisions and standards of this chapter.
(2)
Review subdivision and other proposed new development, including manufactured home parks, to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is located in an area of special flood hazard, all new construction and substantial improvements shall meet the applicable standards of §§ 80-15 through 80-19, regarding general construction standards and, in particular, § 80-15A, Subdivision proposals.
[Amended 11-19-2009 by L.L. No. 13-2009]
(3)
Determine whether any proposed development in an area of special flood hazard may result in physical damage to any other property (e.g., stream bank erosion and increased flood velocities). The local administrator may require the applicant to submit additional technical analyses and data necessary to complete the determination. If the proposed development may result in physical damage to any other property or fails to meet the requirements of §§ 80-15 through 80-19, regarding general construction standards, no permit shall be issued. The applicant may revise the application to include measures that mitigate or eliminate the adverse effects and resubmit the application.
[Amended 11-19-2009 by L.L. No. 13-2009]
(4)
Determine that all necessary permits have been received from those
governmental agencies from which approval is required by state or
federal law.
B.
Use of other flood data.
(1)
When the Federal Emergency Management Agency has designated areas of special flood hazard on the community's Flood Insurance Rate Map (FIRM) but has neither produced water surface elevation data (these areas are designated Zone A or V on the FIRM) nor identified a floodway, the local administrator shall obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, including data developed pursuant to § 80-13G, as criteria for requiring that new construction, substantial improvements or other proposed development meet the requirements of this chapter.
(2)
When base flood elevation data are not available, the local administrator
may use flood information from any other authoritative source, such
as historical data, to establish flood elevations within the areas
of special flood hazard, for the purposes of this chapter.
C.

(1)
Notify adjacent communities and the New York State Department of
Environmental Conservation prior to permitting any alteration or relocation
of a watercourse, and submit evidence of such notification to the
Regional Director, Region II, Federal Emergency Management Agency.
(2)
Determine that the permit holder has provided for maintenance within
the altered or relocated portion of said watercourse so that the flood-carrying
capacity is not diminished.
D.
Construction stage.
(1)
In Zones A1-A30, AE and AH, and also Zone A if base flood elevation
data are available, upon placement of the lowest floor or completion
of floodproofing of a new or substantially improved structure, obtain
from the permit holder a certification of the as-built elevation of
the lowest floor or floodproofed elevation, in relation to mean sea
level. The certificate shall be prepared by or under the direct supervision
of a licensed land surveyor or professional engineer and certified
by same. For manufactured homes, the permit holder shall submit the
certificate of elevation upon placement of the structure on the site.
A certificate of elevation must also be submitted for a recreational
vehicle if it remains on a site for 180 consecutive days or longer
(unless it is fully licensed and ready for highway use).
(2)
Any further work undertaken prior to submission and approval of the
certification shall be at the permit holder's risk. The local
administrator shall review all data submitted. Deficiencies detected
shall be cause to issue a stop-work order for the project unless immediately
corrected.
E.
Inspections. The local administrator and/or the developer's
engineer or architect shall make periodic inspections at appropriate
times throughout the period of construction in order to monitor compliance
with permit conditions and enable said inspector to certify, if requested,
that the development is in compliance with the requirements of the
floodplain development permit and/or any variance provisions.
F.
Stop-work orders.
(1)
The local administrator shall issue, or cause to be issued, a stop-work order for any floodplain development found ongoing without a development permit. Disregard of a stop-work order shall subject the violator to the penalties described in § 80-9 of this chapter.
(2)
The local administrator shall issue, or cause to be issued, a stop-work order for any floodplain development found noncompliant with the provisions of this chapter and/or the conditions of the development permit. Disregard of a stop-work order shall subject the violator to the penalties described in § 80-9 of this chapter.
G.
Certificate of compliance.
(1)
In areas of special flood hazard, as determined by documents enumerated in § 80-6, it shall be unlawful to occupy or to permit the use or occupancy of any building or premises, or both, or part thereof hereafter created, erected, changed, converted or wholly or partly altered or enlarged in its use or structure until a certificate of compliance has been issued by the local administrator stating that the building or land conforms to the requirements of this chapter.
(2)
A certificate of compliance shall be issued by the local administrator
upon satisfactory completion of all development in areas of special
flood hazard.
(3)
Issuance of the certificate shall be based upon the inspections conducted as prescribed in § 80-14E, Inspections, and/or any certified elevations, hydraulic data, floodproofing, anchoring requirements or encroachment analyses which may have been required as a condition of the approved permit.
[Amended 11-19-2009 by L.L. No. 13-2009]

during a flood and to resist hydrostatic and hydrodynamic loads and
stresses. Electrical wiring and outlets, switches, junction boxes
and panels shall be elevated to or above the base flood elevation
unless they conform to the appropriate provisions of the electrical
part of the Building Code of New York State or the Residential Code
of New York State for location of such items in wet locations;
(2)
New and replacement water supply systems shall be designed to minimize
or eliminate infiltration of floodwaters into the system;
(3)
New and replacement sanitary sewage systems shall be designed to
minimize or eliminate infiltration of floodwaters. Sanitary sewer
and storm drainage systems for buildings that have openings below
the base flood elevation shall be provided with automatic backflow
valves or other automatic backflow devices that are installed in each
discharge line passing through a building's exterior wall; and
(4)
On-site waste disposal systems shall be located to avoid impairment
to them or contamination from them during flooding.
A.
Elevation. The following standards apply to new and substantially improved residential structures located in areas of special flood hazard, in addition to the requirements in § 80-15A, Subdivision proposals, and § 80-15B, Encroachments, and § 80-16, Construction standards for all structures.
(1)
Within Zones A1-A30, AE and AH and also Zone A if base flood elevation
data are available, new construction and substantial improvements
shall have the lowest floor (including basement) elevated to or above
two feet above the base flood elevation.
(2)
Within Zone A, when no base flood elevation data are available, new
and substantially improved structures shall have the lowest floor
(including basement) elevated at least three feet above the highest
adjacent grade.
(3)
Within Zone AO, new and substantially improved structures shall have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as two feet above the depth number specified in feet on the community's Flood Insurance Rate Map enumerated in § 80-6 (at least two feet if no depth number is specified).
[Amended 11-19-2009 by L.L. No. 13-2009]
(4)
Within Zones AH and AO, adequate drainage paths are required to guide
floodwaters around and away from proposed structures on slopes.
The following standards apply to new and substantially improved commercial, industrial and other nonresidential structures located in areas of special flood hazard, in addition to the requirements in § 80-15A, Subdivision proposals, and § 80-15B, Encroachments, and § 80-16, Construction standards for all structures.
A.
Within Zones A1-A30, AE and AH, and also Zone A if base flood elevation
data are available, new construction and substantial improvements
of any nonresidential structure, together with attendant utility and
sanitary facilities, shall either:
(1)
Have the lowest floor, including basement or cellar, elevated to
or above two feet above the base flood elevation; or
(2)
Be floodproofed so that the structure is watertight below two feet
above the base flood elevation 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.
B.
Within Zone AO, new construction and substantial improvements of
nonresidential structures shall:
(1)
Have the lowest floor (including basement) elevated above the highest
adjacent grade at least as high as two feet above the depth number
specified in feet on the community's FIRM (at least two feet
if no depth number is specified); or
(2)
Together with attendant utility and sanitary facilities, be completely
floodproofed to that level to meet the floodproofing standard specified
in § 80-18A2.
[Amended 11-19-2009 by L.L. No. 13-2009]
C.
If the structure is to be floodproofed, a licensed professional engineer
or architect shall develop and/or review structural design, specifications,
and plans for construction. A floodproofing certificate or other certification
shall be provided to the local administrator that certifies the design
and methods of construction are in accordance with accepted standards
of practice for meeting the provisions of § 80-18A2, including
the specific elevation (in relation to mean sea level) to which the
structure is to be floodproofed.
[Amended 11-19-2009 by L.L. No. 13-2009]
D.
Within Zones AH and AO, adequate drainage paths are required to guide
floodwaters around and away from proposed structures on slopes.
E.
Within Zone A, when no base flood elevation data are available, the
lowest floor (including basement) shall be elevated at least three
feet above the highest adjacent grade.
The following standards, in addition to the standards in § 80-15, General construction standards, and § 80-16, Construction standards for all structures, apply, as indicated, in areas of special flood hazard to manufactured homes and to recreational vehicles which are located in areas of special flood hazard.
A.
B.
A manufactured home that is placed or substantially improved in Zones
A1-A30, AE and AH shall be elevated on a permanent foundation such
that the lowest floor is elevated to or above two feet above the base
flood elevation and is securely anchored to an adequately anchored
foundation system to resist flotation, collapse and lateral movement.
C.
Within Zone A, when no base flood elevation data are available, new
and substantially improved manufactured homes shall be elevated such
that the manufactured home chassis is supported by reinforced piers
or other foundation elements of at least equivalent strength that
are no less than 36 inches in height above grade and are securely
anchored to an adequately anchored foundation system to resist flotation,
collapse or lateral movement.
A.
The Zoning Board of Appeals established by the Town of Esopus shall
hear and decide appeals and requests for variances from the requirements
of this chapter.
B.
The Zoning Board of Appeals shall hear and decide appeals when it
is alleged 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 Zoning Board of Appeals 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 Zoning Board of Appeals 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; and
(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,

E.
Upon consideration of the factors of § 80-20D and the purposes of this chapter, the Zoning Board of Appeals may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter.
[Amended 11-19-2009 by L.L. No. 13-2009]
F.
The local administrator shall maintain the records of all appeal
actions, including technical information, and shall 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, providing that the items in § 80-20D4
have been fully considered. As the lot size increases beyond the 1/2
acre, the technical justification required for issuing the variance
increases.
[Amended 11-19-2009 by L.L. No. 13-2009]
B.
Variances may be issued for the repair or rehabilitation of historic
structures upon determination that:
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, extraordinary
public expense, create nuisances, cause fraud on or victimization
of the public or conflict with existing local laws or ordinances.
