This article is not intended to interfere with, abrogate, or
annul any other local law, rule or regulation, statute, or other provision
of law. The requirements of this article should be considered minimum
requirements, and where any provision of this article imposes restrictions
different from those imposed by any other local law, rule or regulation,
or other provision of law, whichever provisions are more restrictive
or impose higher protective standards for human health and/or the
environment shall be considered to take precedence. Construction activities
that involve land disturbance may also require additional compliance
measures detailed in other regulations and/or local laws.
In accordance with Article 21 of the Village Law of the State
of New York and Article 3 of the Municipal Home Rule Law of the State
of New York, the Village Board of Trustees has the authority to enact
laws for the purpose of promoting the health, safety, or general welfare
of the Village, including the protection and preservation of the property
of its inhabitants. By the same authority, the Village Board of Trustees
may include in any such law provisions for the appointment of any
municipal employees to effectuate and administer such law.
All persons shall comply with the requirements of this article,
unless a written request is filed to waive the requirements in part
or whole. Requests to waive any requirements of this article shall
be submitted to the Village for approval.
A. The minimum requirements, for stormwater management may be waived
in whole or in part upon written request of the applicant, provided
that at least one of the following conditions applies:
(1) It can be demonstrated that the proposed development is not likely
to impair attainment of the objectives of this article.
(2) Alternative minimum requirements for on-site management of stormwater
discharges have been established in a stormwater management plan that
has been approved by the Village, and the implementation of the plan
is required by local law. These practices are encouraged in order
to minimize the reliance on structural practices. Credit in the form
of reductions in the amount of stormwater that must be managed can
be earned through the use of nonstructural practices that reduce the
generation of stormwater from the site. These nonstructural practices
are explained in detail in the manual Better Site Design: A Handbook
for Changing Development Rules in Your Community. Applicants wishing
to obtain credit for use of nonstructural practices must ensure that
these practices are documented and remain unaltered by subsequent
property owners.
(3) Provisions are made to manage stormwater by an off-site facility.
The off-site facility is required to be in place, to be designed and
adequately sized to provide a level of stormwater control that is
equal to or greater than that which would be afforded by on-site practices
and there is a legally obligated entity responsible for long-term
operation and maintenance of the stormwater practice.
(4) The Village finds that meeting the minimum on-site management requirements
is not feasible due to the natural or existing physical characteristics
of a site.
(5) Nonstructural practices will be used on the site that reduce:
(a)
The generation of stormwater from the site;
(b)
The size and cost of stormwater storage; and
(c)
The pollutants generated at the site.
B. In instances where one of the conditions above applies, the Village
may grant a waiver from strict compliance with these stormwater management
provisions, as long as acceptable mitigation measures are provided.
However, to be eligible for a variance, the applicant must demonstrate
to the satisfaction of the Village that the variance will not result
in the following impacts to downstream waterways:
(1) Deterioration of existing culverts, bridges, dams, and other structures;
(2) Degradation of biological functions or habitat;
(3) Accelerated stream-bank or streambed erosion or siltation;
(4) Increased threat of flood damage to public health, life, property.
C. Furthermore, where compliance with minimum requirements for stormwater
management is waived, the applicant will satisfy the minimum requirements
by meeting one of the mitigation measures selected by the Village.
Mitigation measures may include, but are not limited to, the following:
(1) The purchase and donation of privately owned lands, or the grant of an easement to be dedicated for preservation and/or reforestation (dedication or easement of land, see §
276-21 below). These lands should be located adjacent to the stream corridor in order to provide permanent buffer areas to protect water quality and aquatic habitat.
(2) The creation of a stormwater management facility or other drainage
improvements on previously developed properties, public or private,
that currently lack stormwater management facilities designed and
constructed in accordance with the purposes and standards of this
article.
(3) Monetary contributions (fee in lieu of, see §
276-21 below) to a dedicated fund for stormwater management activities.
Unless judged by the Village to be exempt or granted a waiver,
the following performance criteria shall be addressed for stormwater
management at all sites:
A. All site designs shall establish stormwater management practices
to control the peak flow rates of stormwater discharge associated
with specified design storms and reduce the generation of stormwater.
These practices should seek to utilize pervious areas for stormwater
treatment and to infiltrate stormwater runoff from driveways, sidewalks,
rooftops, parking lots, and landscaped areas to the maximum extent
practical to provide treatment for both water quality and quantity.
B. All stormwater runoff generated from new development shall not discharge
untreated stormwater directly into a jurisdictional wetland or local
water body without adequate treatment. Where such discharges are proposed,
the impact of the proposal on wetland functional values shall be assessed
using a method acceptable to the Village. In no case shall the impact
on functional values be any greater than that allowed by the Army
Corps of Engineers (ACE) or the appropriate state agency responsible
for natural resources.
C. Annual groundwater recharge rates shall be maintained by promoting
infiltration through the use of structural and nonstructural methods.
At a minimum, annual recharge from the post-development site shall
mimic the annual recharge from predevelopment site conditions.
D. In order to protect stream channels from degradation, specific channel
protection criteria shall be provided as prescribed in the Village
Design Criteria and/or the New York State Stormwater Management Design
Manual.
E. Stormwater discharges to critical areas with sensitive resources
may be subject to additional performance criteria, or may need to
utilize or restrict certain stormwater management practices.
F. Stormwater discharges from land uses or activities with higher potential
pollutant loadings, known as "hotspots," may require the use of specific
structural STPs and pollution prevention practices.
G. Prior to design, applicants are required to consult with the Village
to determine if they are subject to additional stormwater design requirements.
H. The calculations for determining peak flows, WQv, as found in the
New York State Stormwater Management Design Manual, shall be used
for sizing all stormwater management practices.
The applicant shall consult the Village's Design Criteria and
the New York State Stormwater Management Design Manual for guidance
and requirements related to stormwater management design criteria.
These manual(s) cover items such as but not necessarily limited to:
A. Minimum control requirements.
D. Pretreatment requirements.
E. Treatment/geometry conditions.
F. Environmental/landscaping standards.
H. Nonstructural stormwater practices.
All applicants are responsible for maintaining the grading of
the site so that it is consistent with the approved as-built plans.
There shall be no post-construction alterations to the landscape that
are not included on the approved landscape plan. Temporary landscape
alterations, such as those associated with utility excavations and
landscaping activities, must be restored to conditions that are consistent
with the approved as-built plans.
