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 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.
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.

prior to approval of the final stormwater design plan.
Each contractor and subcontractor identified in the SWPPP who
will be involved in soil disturbance and/or stormwater management
practice installation shall sign and date a copy of the following
certification statement before undertaking any land development activity:
"I certify under penalty of law that I understand and agree to comply
with the terms and conditions of the stormwater pollution prevention
plan. I also understand that it is unlawful for any person to cause
or contribute to a violation of water quality standards." The certification
must include the name and title of the person providing the signature,
address and telephone number of the contracting firm, the address
(or other identifying description) of the site, and the date the certification
is made. The certification statement(s) shall become part of the SWPPP
for the land development activity. A copy of the SWPPP shall be retained
at the site of the land development activity during construction,
from the date of initiation of construction activities to the date
of final stabilization.
All land development activities shall be subject to the following
performance and design criteria:
A. Technical standards. For the purpose of this article, 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 article:
(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"); and
(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").
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.
The Town may require any person undertaking land development
activities regulated by this article 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.
