[HISTORY: Adopted by the Board of Trustees of the Village of Groton 3-23-1987
as L.L. No. 3-1987. Sections 109-8B and 109-11B(1) amended
at time of adoption of Code; see Ch. 1, General Provisions, Art. I. Other
amendments noted where applicable.]
The Board of Trustees of the Village of Groton finds that the potential
and/or actual damages from flooding and erosion may be a problem to the residents
of the Village of Groton 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.Â
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.Â
Require that uses vulnerable to floods, including facilities
which serve such uses, be protected against flood damage at the time of initial
construction.
C.Â
Control the alteration of natural floodplains, stream
channels and natural protective barriers which are involved in the accommodation
of floodwaters.
D.Â
Control filling, grading, dredging and other development
which may increase erosion or flood damages.
E.Â
Regulate the construction of flood barriers which will
unnaturally divert floodwaters or which may increase flood hazards to other
lands.
F.Â
Qualify for and maintain participation in the National
Flood Insurance Program.
The objectives of this chapter are to:
A.Â
Protect human life and health.
B.Â
Minimize expenditure of public money for costly flood
control projects.
C.Â
Minimize the need for rescue and relief efforts associated
with flooding and generally undertaken at the expense of the general public.
D.Â
Minimize prolonged business interruptions.
E.Â
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.Â
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.Â
Provide that developers are notified that property is
in an area of special flood hazard.
H.Â
Ensure that those who occupy the areas of special flood
hazard assume responsibility for their actions.
A.Â
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.

permitted within such areas will be free from flooding or flood damages. This
chapter shall not create liability on the part of the Village of Groton, 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.
B.Â
The Village of Groton does not guarantee, warrant or
represent that any structure or other improvements designed and constructed
in accordance with this chapter will not be subject to flood damage and hereby
disclaims any liability on the part of the village or any of its officers,
employees, agents or contractors or anyone else acting in behalf of the village
for any injuries or damages that may occur as a result of reliance upon and
compliance with these regulations or the issuance of a permit or of any other
action taken by the village and the aforesaid agencies and persons pursuant
to this chapter or from the failure to comply with any provision of these
regulations or if the work has not been properly performed.
The Code Enforcement Officer is hereby appointed the local administrator
to administer and implement this chapter by granting or denying development
permit applications in accordance with its provisions.

If the structure is to be floodproofed:
[1]Â
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, with structural components
having the capability of resisting hydrostatic and hydrodynamic loads and
effects of buoyancy.
[2]Â
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)Â
The local administrator shall maintain on record a copy
of all such certificates noted in this subsection.
C.Â
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 § 109-12B, or two feet above the highest adjacent grade where no elevation data is available.
(1)Â
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)Â
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)Â
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

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 § 109-4, Definitions and word usage.) 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 §§ 109-6 and 109-12B, 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.Â
The Zoning Board of Appeals, as established by the Village
of Groton, shall hear and decide appeals and requests for variances from the
requirements of this chapter.
B.Â
The Zoning Board of Appeals 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.Â
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.Â
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)Â
The danger that materials may be swept onto other lands
to the injury of others.
(2)Â
The danger to life and property due to flooding or erosion
damage.
(3)Â
The susceptibility of the proposed facility and its contents
to flood damage and the effect of such damage on the individual owner.
(4)Â
The importance of the services provided by the proposed
facility to the community.
(5)Â
The necessity to the facility of a waterfront location,
where applicable.
(6)Â
The availability of alternative locations for the proposed
use which are not subject to flooding or erosion damage.
(7)Â
The compatibility of the proposed use with existing and
anticipated development.
(8)Â
The relationship of the proposed use to the Comprehensive
Plan and floodplain management program of that area.
(9)Â
The safety of access to the property in times of flood
for ordinary and emergency vehicles.
(10)Â
The costs to local governments and the dangers associated
with conducting search and rescue operations during periods of flooding.
(11)Â
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)Â
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.Â
Upon consideration of the factors of Subsection D 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.
F.Â
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.Â
Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half (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 § 109-16D(1) through (12) have been fully considered. As the lot size increases beyond the one-half (1/2) acre, the technical justification required for issuing the variance increases.
B.Â
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 contributing structures procedures set forth in the remainder
of this section.
C.Â
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.Â
Variances shall not be issued within any designated floodway
if any increase in flood levels during the base flood discharge would result.
E.Â
Variances shall be only issued upon a determination that
the variance is the minimum necessary, considering the flood hazard, to afford
relief.
F.Â
Variances shall only be issued upon retrieving written
justification:
(1)Â
A showing of good and sufficient cause;
(2)Â
A determination that failure to grant the variance would
result in exceptional hardship to the applicant; and
(3)Â
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.Â
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 resulting from lowest floor elevation.
