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
soil 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 and resulting disturbed areas;
H. The regulation of stormwater runoff discharges from land
development activities controls and minimizes increases in stormwater runoff
rates and volumes, soil erosion, stream channel erosion, and nonpoint source
pollution associated with stormwater runoff and is in the public interest,
as it will minimize threats to public health and safety.
I. Regulation of land development and other land-disturbing
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 residents of the Town and to address the findings in §
85-1 above. 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 and disturbance 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
and disturbance activities in order to reduce flooding, siltation, increases
in stream temperature, and soil erosion and maintain the integrity of stream
channels.
D. Minimize increases in pollution caused by stormwater
runoff from land development and disturbance 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.
F. Reduce stormwater runoff rates and volumes, soil erosion
and nonpoint source pollution, wherever possible, through stormwater management
practices and ensure that these management practices are properly maintained
and eliminate threats to public safety.

under this chapter shall have the meaning as set forth in this section.

capacity or original purpose of a facility.
D. Repairs to any stormwater management practice or facility
deemed necessary by the Stormwater Management Officer.
E. Any part of a subdivision if a plat for the subdivision
has been approved by the Planning Board on or before the effective date of
this chapter.
F. Land development activities for which a building permit
has been approved on or before the effective date of this chapter.

with an existing structure.
All land development activities shall be subject to the following performance
and design criteria:
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

A above and the SWPPP shall be prepared by a licensed professional.
C. 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.
The Town may require any person undertaking land development activities
regulated by this chapter to pay reasonable costs at prevailing rates for
review of SWPPPs, inspections, or SMP maintenance performed by the Town or
performed by a third party for the Town.
