Water & Stormwater
View the Orange County Water Master Plan (PDF).
A watershed plan is essentially an intermunicipal comprehensive plan that focuses on water resources. Watershed plans are intended to provide a management framework for restoring impaired water bodies as well as for safeguarding healthy water bodies. The rationale for watershed management is that if we properly manage activities on land, then we will be protecting water quality.

The Phase II Stormwater Program of the New York State Department of Environmental Conservation (NYSDEC) requires certain municipalities and other entities that operate Municipal Separate Storm Sewer Systems (MS4s) to prepare and implement a Stormwater Management Plan. Orange County is considered an MS4 area, subject to these regulations.
The Orange County MS4 Annual Report for 2020 is accepting public comment now through May 28, 2020.
