The updated New York State Stormwater Management Design Manual with new Technical Standards for green infrastructure was released earlier this month.
The New York State Stormwater Management Design Manual provides designers with a general overview on how to size, design, select, and locate stormwater management practices at a development site to comply with State stormwater performance standards. This manual is a key component of the Phase II State Pollution Discharge Elimination System (SPDES) general permit for stormwater runoff from construction activities from all sizes of disturbance.
This manual has been prepared by the Center for Watershed Protection for New York State Department of Environmental Conservation and made available to the Empire State Chapter of the Soil and Water Conservation Society for distribution.
The New York State Stormwater Management Design Manual is available for download at this site. Alternatively, the document may be purchased as a paper copy by sending an order form to the Empire State Chapter Soil and Water Conservation Society.
