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 law:
(1)Â
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 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).
C.Â
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.Â
Maintenance and inspection during construction.
(1)Â
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

(2)Â
For land development activities as defined in § 171-6 of this chapter and meeting Condition A, B or C in § 171-7B(2), the applicant shall have a qualified professional conduct site inspections and document the effectiveness of all erosion and sediment control practices every seven days for sites with five acres or less exposed and twice every seven days, separated by two full days, for sites with more than five acres exposed or in accordance with the current general permit for stormwater discharges from construction activity. Inspection reports shall be maintained in a site logbook.
[Amended 4-7-2010 by L.L. No. 3-2010]
B.Â
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 Town of Union 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 Union.
C.Â

of permanent stormwater management practices (SMPs) installed in accordance
with this chapter shall ensure they are operated and maintained to
achieve the goals of this chapter. Proper operation and maintenance
also includes, as a minimum, the following:
[Amended 4-7-2010 by L.L. No. 3-2010]

The maintenance agreement shall be consistent with the terms and conditions of Schedule B of this chapter entitled Sample Stormwater Control Facility Maintenance Agreement.[1] The Town of Union, in lieu of a maintenance agreement,
at its sole discretion, may 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.
