All land development activities shall be subject
to the following performance and design criteria:
A. Technical standards. For purposes 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, 2005, most current version or its successor, hereafter referred
to as the "Erosion Control Manual").
B. Equivalence to technical standards. Where stormwater management practices are not in accordance with technical standards, the applicant or developer must demonstrate equivalence to the technical standards set forth in Subsection
A 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.
