[HISTORY: Adopted by the Board of Trustees of the Village
of Sagaponack 1-17-2012 by L.L. No. 1-2012. Amendments noted where
applicable.]
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 water-borne
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 baseflow;
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; and
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 chapter 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 § 187-1 hereof. This chapter 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.
In accordance with § 10 of the Municipal Home Rule
Law of the State of New York, the Village Board of Trustees Sagaponack

(2)
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 Village of Sagaponack
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 professional engineer.
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.
D.
Submission of reports. The Village of Sagaponack Stormwater Management
Officer may require monitoring and reporting from entities subject
to this chapter as are necessary to determine compliance with this

A.
Construction completion guarantee. In order to ensure the full and
faithful completion of all land development activities related to
compliance with all conditions set forth by the Village of Sagaponack
in its approval of the stormwater pollution prevention plan, the Village
of Sagaponack 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 Village
of Sagaponack as the beneficiary. The security shall be in an amount
to be determined by the Village of Sagaponack based on submission
of final design plans, with reference to actual construction and landscaping
costs. The performance guarantee shall remain in force until the surety
is released from liability by the Village of Sagaponack, 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 Village of Sagaponack. Per
annum interest on cash escrow deposits shall be reinvested in the
account until the surety is released from liability.
B.
Maintenance guarantee. 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 Village of Sagaponack with an irrevocable
letter of credit from an approved financial institution or surety
with a principal place of business in the Town of Southampton 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 Village of Sagaponack
may draw upon the account to cover the costs of proper operation and
maintenance, including engineering and inspection costs.
The Village of Sagaponack may require entities subject to this
