Editor's Note: This local law superseded former Ch. 48,
Flood Hazard Areas, which consisted of the following: Art. I, Flood
Hazard Reduction, adopted 3-11-1975; and Art. II, Review of Development
Proposals, adopted 4-22-1978.
The Town Board of the Town of Kingsbury finds that the potential
and/or actual damages from flooding and erosion may be a problem to
the residents of the Town of Kingsbury and that such damages may include
the 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:
A.
To protect human life and health.
B.
To minimize expenditure of public money for costly flood-control
projects.
C.
To minimize the need for rescue and relief efforts associated with
flooding and generally undertaken at the expense of the general public.
D.
To minimize prolonged business interruptions.
E.
To minimize damage to public facilities and utilities such as water
and gas mains; electric, telephone and sewer lines; and streets and
bridges located in areas of special flood hazard.
F.
To 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.
To provide that developers are notified that property is in an area
of special flood hazard.
H.
To 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
application.

[Amended 6-12-1989 by L.L. No. 1-1989]
A.
The areas of special flood hazard have been identified by the Federal
Emergency Management Agency on Flood Insurance Rate Maps enumerated
on Map Index No. 361235 0001-0004, dated September 7, 1979.
B.
The above documents are hereby adopted and declared to be a part
of this chapter and are filed at the Town Clerk's office, Town
of Kingsbury.
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 will 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 shall prevent the Town of Kingsbury from taking such 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 §§ 145-16 and 145-17, 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 that 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 Kingsbury, 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 Code Enforcement Officer of the Town of Kingsbury 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 of any other development within the area of special flood hazard as established in § 145-6. 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:
(1)
Elevation, in relation to mean sea level, of the proposed lowest
floor, including basement or cellar, of all structures.
(2)
Elevation, in relation to mean sea level, to which any nonresidential
structure will be floodproofed.
(3)
When required, a certificate from a licensed professional engineer or architect that the utility floodproofing will meet the criteria in § 145-13C(1).
(4)
Certificate from a licensed professional engineer or architect that the nonresidential floodproofed structure will meet the floodproofing criteria in § 145-14B.
(5)
Description of the extent to which any watercourse will be altered
or relocated as a result of proposed development.
B.
Construction stage. Upon placement of the lowest floor or floodproofing
by whatever means, it shall be the duty of the permit holder to submit
to the local administrator a certificate of the as-built elevation
of the lowest floor or floodproofed elevation in relation to mean
sea level. The elevation certificate shall be prepared by or under
the direct supervision of a licensed land surveyor or professional
engineer and certified by the same. When floodproofing is utilized
for a particular building, the floodproofing certificate shall be
prepared by or under the direct supervision of a licensed professional
engineer or architect and certified by the same. Any further work
undertaken prior to submission and approval of the certificate 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.

(4)
Base flood elevation data shall be provided for subdivision proposals
and other proposed developments, including proposals for manufactured
home parks and subdivisions, greater than either 50 lots or five acres.
E.
Encroachments.
(1)
All proposed development in riverine situations where no flood elevation data is available (unnumbered A Zones) shall be analyzed to determine the effects on the flood-carrying capacity of the areas of special flood hazard set forth in § 145-12A(3). This may require the submission of additional technical data to assist in the determination.
(2)
In all areas of special flood hazard in which base flood elevation data is available pursuant to § 145-12B or 145-13D(4) and no floodway has been determined, the cumulative effects of any proposed development, when combined with all other existing and anticipated development, shall not increase the water surface elevation of the base flood more than one foot at any point.
In all areas of special flood hazard where base flood elevation data has been provided as set forth in § 145-6, Basis for establishing areas of special flood hazard, and § 145-12B, Use of other base flood and floodway data, the following standards are required:
A.

of any residential 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 shall be required for every square foot of enclosed
area subject to flooding.
(b)
The bottom of all such openings shall be no higher than one
foot above the lowest adjacent finished grade.
(c)

B.
Nonresidential construction.
(1)
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 to the base flood level.
(a)
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:
[1]
A minimum of two openings having a total net area of not less
than one square inch shall be required for every square foot of enclosed
area subject to flooding.
[2]
The bottom of all such openings shall be no higher than one
foot above the lowest adjacent finished grade.
[3]
Openings may be equipped with louvers, valves, screens or other
coverings or devices, provided that they permit the automatic entry
and exit of floodwaters.
(b)
If the structure is to be floodproofed:
[1]
A licensed professional engineer or architect shall develop
and/or review structural design, specifications and plans for 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.
[2]
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.
(2)
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.
(1)
New construction or substantial improvements of structures, 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 shall be required for every square foot of enclosed
area subject to flooding.
(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, § 145-4). 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 § 145-12B, 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.
A.
The Planning Board as established by the Town of Kingsbury shall
hear and decide appeals and requests for variances from the requirements
of this chapter.
B.
The Planning Board 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 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 § 145-16D and the purpose 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 § 145-16D(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:
(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.
(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.
