All land development activities shall be subject to the following
performance and design criteria:
A. Technical standards. For the purpose of this article, the following
documents shall serve as the official guides and specifications for
stormwater management. Stormwater management practices that are designed
and constructed in accordance with these technical documents shall
be presumed to meet the standards imposed by this article:
(1)
The New York State Stormwater Management Design Manual (New
York State Department of Environmental Conservation, most current
version or its successor, hereafter referred to as the "Design Manual");
and
(2)
The New York Standards and Specifications for Erosion and Sediment
Control (Empire State Chapter of the Soil and Water Conservation Society,
most current version or its successor, hereafter referred to as the
"Erosion Control Manual").
B. Water quality standards. No land development activity shall off-site
transport of sediment and/or increase runoff volume.
The Board of Trustees finds that the potential and/or actual
damages from flooding and erosion may be a problem to the residents
of the Village 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. It is the
purpose of this article 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 article are:
A. To protect human life and health;
B. To minimize the 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, 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; and,
H. To ensure that those who occupy the areas of special flood hazard
assume responsibility for their actions.
Unless specifically defined elsewhere in this chapter, words or phrases used in this article shall be interpreted
so as to give them the meaning they have in common usage and to give
this article its most reasonable application.
This article shall apply to all areas of special flood hazard
within the jurisdiction of the Village.
The degree of flood protection required by this article 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 article 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 article shall not create liability
on the part of the Village, any officer or employee thereof or the
Federal Emergency Management Agency for any flood damages that result
from reliance on this article or any administrative decision lawfully
made thereunder.
The Director is hereby appointed local administrator to administer
and implement this article by granting or denying floodplain development
permits in accordance with its provisions.
The applicant shall provide at least the following information,
where applicable (additional information may be required on the permit
application form):

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 is available. Upon completion of the
lowest floor, the permittee 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, of the bottom
of the lowest structural member of the lowest floor, excluding pilings
and columns, of any new or substantially improved structure to be
located in Zones V1 — V30 or VE, or Zone V if base flood elevation
data is available. Upon completion of the lowest floor, the permittee
shall submit to the Building Inspector the as-built elevation, certified
by a licensed professional engineer or surveyor;
C. 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
permittee shall submit to the Building Inspector the as-built floodproofed
elevation, certified by a professional engineer or surveyor;
D. A certificate from a licensed professional engineer or architect
that any utility floodproofing will meet the criteria of this article;
E. Utilities: a certificate from a licensed professional engineer or
architect that any nonresidential floodproofed structure will meet
the floodproofing of this article;
F. 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 this
article;
G. Basis for establishing areas of special flood hazard. When notified
by the Director the applicant 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;
H. A technical analysis by a licensed professional engineer, if required
by the Director, which shows whether proposed development to be located
in an area of special flood hazard may result in physical damage to
any other property; and
I. In Zone A, when no base flood elevation data is 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 Director shall include, but shall not be limited
to, the following:
A. Permit application review. The Director shall conduct the following permit application review before issuing a floodplain development permit. The Director shall review all applications for completeness, particularly with the requirements of §
106-153, and for compliance with the provisions and standards of this article;
B. Review subdivision and other proposed new development, including
manufactured home communities, to determine whether proposed building
sites will be reasonably safe from flooding. If a proposed building
