§ 86-7. Performance and design criteria for stormwater management and erosion and sediment control.

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 specifications and standards for stormwater management. Stormwater management practices that are designed and constructed in accordance with the documents set forth herein 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, or any amendments thereto, 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 (or most current version), or any amendments thereto, hereafter referred to as the "Erosion Control Manual.")

B. 

Equivalence to technical standards. Where stormwater management practices are not in accordance with the technical specifications or standards, the applicant or developer must demonstrate to the satisfaction of the Stormwater Management Officer that the SWPPP, as prepared by a New York State registered landscape architect (RLA), a certified professional in sediment and erosion control (CPESC) or a professional engineer (PE) licensed in the State of New York, is equivalent to the technical specifications or standards.

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.
