Stormwater and Green Infrastructure

Pollution from stormwater run-off, also known as non-point source pollution - can negatively impact water quality and ecosystem health and has the potential to increase flood flows and infrastructure damage during precipitation events. The County, like many others in New York, is required to implement the NYSDEC’s MS4 Stormwater program. The Department helps to coordinate this program and aims to do so in a way that not only ensures the County’s regulatory compliance but also provides technical support to other regulated municipalities in the County. Successful implementation of this program helps to protect our valuable water resources and helps to prevent flood damage.
