[Added 12-11-2007 by L.L. No. 12-2007]
It is hereby determined that:
A.
Land development activities and associated increases in site impervious
cover often alter the hydrologic response of local watersheds and
increase stormwater runoff rates and volumes, flooding, stream channel
erosion, or sediment transport and deposition;
B.
This stormwater runoff contributes to increased quantities of waterborne
pollutants, including siltation of aquatic habitat for fish and other
desirable species;
C.
Clearing and grading during construction tends to increase soil erosion
and add to the loss of native vegetation necessary for terrestrial
and aquatic habitat;
D.
Improper design and construction of stormwater management practices
can increase the velocity of stormwater runoff, thereby increasing
stream bank erosion and sedimentation;
E.
Impervious surfaces allow less water to percolate into the soil,
thereby decreasing groundwater recharge and stream base flow;
F.
Substantial economic losses can result from these adverse impacts
on the waters of the municipality;
G.
Stormwater runoff, soil erosion and nonpoint source pollution can
be controlled and minimized through the regulation of stormwater runoff
from land development activities;
H.
The regulation of stormwater runoff discharges from land development
activities in order to control and minimize increases in stormwater
runoff rates and volumes, soil erosion, stream, channel erosion, and
nonpoint source pollution associated with stormwater runoff is in
the public interest and will minimize threats to public health and
safety.
I.
Regulation of land development activities by means of performance
standards governing stormwater management and site design will produce
development compatible with the natural functions of a particular
site or an entire watershed and thereby mitigate the adverse effects
of erosion and sedimentation from development.
The purpose of this article and Article XVII of Chapter 43, Zoning, is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing within this jurisdiction and to address the findings of fact in § 56-174 hereof. This article and Article XVII of Chapter 43, Zoning, seeks to meet those purposes by achieving the following objectives:
A.
Meet the requirements of minimum measures 4 and 5 of the SPDES General
Permit for Stormwater Discharges from Municipal Separate Stormwater
Sewer Systems (MS4s), Permit No. GP-02-02, or as amended or revised;
B.
Require land development activities to conform to the substantive
requirements of the NYS Department of Environmental Conservation State
Pollutant Discharge Elimination System (SPDES) General Permit for
Construction Activities GP-02-01 or as amended or revised;
C.
Minimize increases in stormwater runoff from land development activities
in order to reduce flooding, siltation, increases in stream temperature,
and streambank erosion and maintain the integrity of stream channels;
D.
Minimize increases in pollution caused by stormwater runoff from
land development activities which would otherwise degrade local water
quality;
E.
Minimize the total annual volume of stormwater runoff which flows
from any specific site during and following development to the maximum
extent practicable; and
F.
Reduce stormwater runoff rates and volumes, soil erosion and nonpoint
source pollution, wherever possible, through stormwater management
practices and to ensure that these management practices are properly
maintained and eliminate threats to public safety.
This article and Article XVII of Chapter 43, Zoning, shall be applicable to all land development activities as defined in Article XVII of Chapter 43, Zoning.
A.
The municipality shall designate a Stormwater Management Officer who shall accept and review all stormwater pollution prevention plans and forward such plans to the applicable municipal board. The Stormwater Management Officer may review the plans; upon approval by the City Council engage the services of a registered professional engineer to review the plans, specifications and related documents, at a cost not to exceed a fee schedule established by said governing board; or accept the certification of a licensed professional that the plans conform to the requirements of this article and Article XVII of Chapter 43, Zoning.
C.
All land development activities not subject to review as stated in § 56-176B shall be required to submit a stormwater pollution prevention plan (SWPPP) to the Stormwater Management Officer, who shall approve the SWPPP if it complies with the requirements of this article and Article XVII of Chapter 43, Zoning.
The following activities may be exempt from review under this article and Article XVII of Chapter 43, Zoning:
C.
Routine maintenance activities that disturb less than five acres
and are performed to maintain the original line and grade, hydraulic
capacity or original purpose of a facility.
D.
Repairs to any stormwater management practice or facility deemed
necessary by the Stormwater Management Officer.
G.
Cemetery graves.
H.
Installation of fence, sign, telephone, and electric poles and other
kinds of posts or poles.
I.
Emergency activity immediately necessary to protect life, property
or natural resources.
J.
Activities of an individual engaging in home gardening by growing
flowers, vegetable and other plants primarily for use by that person
and his or her family.
K.
Landscaping and horticultural activities in connection with an existing
structure.
If the provisions of any article, section, subsection, paragraph, subdivision or clause of this article and Article XVII of Chapter 43, Zoning, shall be judged invalid by a court of competent jurisdiction, such order of judgment shall not affect or invalidate the remainder of any article, section, subsection, paragraph, subdivision or clause of this article and Article XVII of Chapter 43, Zoning.
The Subdivision Regulations of the City of Yonkers are hereby
amended by adding the following to the information requirements.[1]
The site plan review regulations of the City of Yonkers are
hereby amended by adding the following to the information requirements.[1]
A stormwater pollution prevention plan consistent with the requirements of §§ 56-174 through 56-181 of this article shall be required. The SWPPP shall meet the performance and design criteria and standards in this article and Article XVII of Chapter 43, Zoning. The approved erosion control permit shall be consistent with the provisions of this article and Article XVII of Chapter 43, Zoning.
A.
Erosion and sediment control inspection.
(1)
The City of Yonkers Stormwater Management Officer may require such inspections as necessary to determine compliance with this article and Article XVII of Chapter 43, Zoning, and may either approve that portion of the work completed or notify the applicant wherein the work fails to comply with the requirements of this article and Article XVII of Chapter 43, Zoning, and the stormwater pollution prevention plan (SWPPP) as approved. To obtain inspections, the applicant shall notify the City of Yonkers enforcement official at least 48 hours before any of the following as required by the Stormwater Management Officer:
(a)
Start of construction.
(b)
Installation of sediment and erosion control measures.
(c)
Completion of site clearing.

If any violations are found, the applicant and developer shall be
notified, in writing, of the nature of the violation and the required
corrective actions. No further work shall be conducted except for
site stabilization until any violations are corrected and all work
previously completed has received approval by the Stormwater Management
Officer.
B.
Stormwater management practice inspections. The City of Yonkers Stormwater
Management Officer is responsible for conducting inspections of stormwater
management practices (SMPs). All applicants are required to submit
as-built plans for any stormwater management practices located on
site after final construction is completed. The plan must show the
final design specifications for all stormwater management facilities
and must be certified by a licensed professional engineer registered
with the State of New York.
C.
Inspection of stormwater facilities after project completion. Inspection
programs shall be established on any reasonable basis, including but
not limited to routine inspections; random inspections; inspections
based upon complaints or other notice of possible violations; inspection
of drainage basins or areas identified as higher than typical sources
of sediment or other contaminants or pollutants; inspections of businesses
or industries of a type associated with higher than usual discharges
of contaminants or pollutants or with discharges of a type which are
more likely than the typical discharge to cause violations of state
or federal water or sediment quality standards or the SPDES stormwater
permit; and joint inspections with other agencies inspecting under
environmental or safety laws. Inspections may include, but are not
limited to, reviewing maintenance and repair records; sampling discharges,
surface water, groundwater, and material or water in drainage control
facilities; and evaluating the condition of drainage control facilities
and other stormwater management practices. Any person who conducts
an inspection of the site, whether a City employee or a professional
engineer, must submit a report of his or her findings to the City.
E.
Right-of-entry for inspection. When any new stormwater management facility is installed on private property or when any new connection is made between private property and the public stormwater system, the landowner shall grant to the City of Yonkers the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection as specified in Subsection C.
A.
Construction completion guaranty. In order to ensure the full and
faithful completion of all land development activities related to
compliance with all conditions set forth by the City of Yonkers in
its approval of the stormwater pollution prevention plan, the City
of Yonkers may require the applicant or developer to provide, prior
to construction, a performance bond, cash escrow, or irrevocable letter
of credit from an appropriate financial or surety institution which
guarantees satisfactory completion of the project and names the City
of Yonkers as the beneficiary. The security shall be in an amount
to be determined by the City of Yonkers based on submission of final
design plans, with reference to actual construction and landscaping
costs. The performance guaranty shall remain in force until the surety
is released from liability by the City of Yonkers, provided that such
period shall not be less than one year from the date of final acceptance
or such other certification that the facility(ies) have been constructed
in accordance with the approved plans and specifications and that
a one-year inspection has been conducted and the facilities have been
found to be acceptable to the City of Yonkers. Per-annum interest
on cash escrow deposits shall be reinvested in the account until the
surety is released from liability.
B.
Maintenance guaranty. Where stormwater management and erosion and
sediment control facilities are to be operated and maintained by the
developer or by a corporation that owns or manages a commercial or
industrial facility, the developer, prior to construction, may be
required to provide the City of Yonkers with an irrevocable letter
of credit from an approved financial institution or surety to ensure
proper operation and maintenance of all stormwater management and
erosion control facilities both during and after construction and
until the facilities are removed from operation. If the developer
or landowner fails to properly operate and maintain stormwater management
and erosion and sediment control facilities, the City of Yonkers may
draw upon the account to cover the costs of proper operation and maintenance,
including engineering and inspection costs.
A.
Notice of violation. When the City of Yonkers determines that a land development activity is not being carried out in accordance with the requirements of this article and Article XVII of Chapter 43, Zoning, it may issue a written notice of violation to the landowner. This article and Article XVII of Chapter 43, Zoning, may be enforced by any police officer, fire fighter, sanitation enforcement officer, or any officer or employee of the Building Department or Engineering Department.
