A.
Technical standards. For the purpose of this chapter,
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 chapter:
(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");
(2)
New York Standards and Specifications for Erosion
and Sediment Control (Empire State Chapter of the Soil and Water Conservation
Society, 2004, most current version or its successor, hereafter referred
to as the "Erosion Control Manual");
(3)
New York State Department of Environmental Conservation
"Instruction Manual for Stormwater Construction Permit";
(4)
Best management practices established by Resolution
of the Town Board, which may be updated from time to time.
B.
Water quality standards. Any land development activity
shall not cause an increase in turbidity that will result in substantial
visible contrast to natural conditions in surface waters of the State
of New York.
A.
Maintenance during construction.
(1)
The applicant or developer of the land development
activity shall at all times properly operate and maintain all facilities
and systems of treatment and control (and related appurtenances) which
are installed or used by the applicant or developer to achieve compliance
with the conditions of this chapter. Sediment shall be removed from
sediment traps or sediment ponds whenever their design capacity has
been reduced by 50%.
(2)
The applicant or developer or their representative
shall be on site at all times when construction or grading activity
takes place and shall inspect and document the effectiveness of all
erosion and sediment control practices. Inspection reports shall be
completed every seven days and within 24 hours of any storm event
producing 0.5 inch of precipitation or more. The reports shall be
delivered to the Stormwater Management Officer and also copied to
the site logbook.
B.
Maintenance easement(s). Prior to the issuance of
any approval that has a stormwater management facility as one of the
requirements, the applicant or developer must execute a maintenance
easement agreement that shall be binding on all subsequent landowners
served by the stormwater management facility. The easement shall provide
for access to the facility at reasonable times for periodic inspection
by the approving authority of the Town of East Fishkill to ensure
that the facility is maintained in proper working condition to meet
design standards and any other provisions established by this chapter.
The easement shall be recorded by the grantor in the office of the
County Clerk after approval by the counsel for the Town of East Fishkill.
C.
Maintenance after construction. The owner or operator
of permanent stormwater management practices installed in accordance
with this chapter shall be operated and maintained to achieve the
goals of this chapter. Proper operation and maintenance also includes,
as a minimum, the following:
(1)
A preventive/corrective maintenance program for all
critical facilities and systems of treatment and control (or related
appurtenances) which are installed or used by the owner or operator
to achieve the goals of this chapter.
(2)
Written procedures for operation and maintenance and
training new maintenance personnel.
D.
Maintenance agreements. The Town of East Fishkill
shall approve a formal maintenance agreement for stormwater management
facilities binding on all subsequent landowners and recorded in the
office of the County Clerk as a deed restriction on the property prior
to final plan approval. The maintenance agreement shall be consistent
with the terms and conditions as set forth by the Town Attorney and
the Building Inspector. The Town of East Fishkill, in lieu of a maintenance
agreement, at its sole discretion, may establish a drainage district
to accept dedication of any existing or future stormwater management
facility, provided such facility meets all the requirements of this
chapter and includes adequate and perpetual access and sufficient
area, by easement or otherwise, for inspection and regular maintenance.

A.
The Stormwater
Management Officer shall develop, implement and enforce a program
to reduce pollutants in stormwater runoff to the small MS4 from construction
activities that result in a land disturbance of greater than or equal
to 5,000 square feet within the New York City watershed area.
B.
Standards.
At a minimum, the program must provide the equivalent protection to
the New York State Department of Environmental Conservation general
permit for stormwater discharges from construction activity and should
include the following standards:
(1)
Requiring
erosion and sediment controls designed in accordance with the most
current version of the technical standards in the New York Standards
and Specification for Erosion and Sediment Control for all construction
activities that serve between 5,000 square feet and one acre of land.
(2)
Inspections
shall be performed to insure compliance with this regulation.
C.
Postconstruction
management. Projects of less than one acre which are within the New
York City watershed area that are part of a larger common plan of
development or sale shall be inspected postconstruction in accordance
with the most current version of the technical standards in the New
York State Stormwater Management Design Manual, including the enhanced
phosphorous removal of designed standards. The postconstruction stormwater
management controls are to be designed in accordance with the final
version of the enhanced phosphorous removal design standards by September
30, 2008.
D.
Retrofit
programs. A program shall be established for identified areas that
are identified with erosion and/or pollutant loading problems. The
project will be based on the phosphorous reduction potential of the
specific retrofit being constructed/installed, the ability to use
standard proven technologies and the economic feasibility of constructing/installing
the retrofit.
