DEC Region 3 Office
Serving the Catskills, Lower Hudson Valley and Long Island Sound
DEC Region 3 - a diverse region that covers the Lower Hudson Valley from the Long Island Sound in Westchester County to the Catskills and includes large metropolitan cities such as Yonkers and the rural landscape of Sullivan County.
We face numerous challenges and opportunities in Region 3, including protecting the Great Swamp in Putnam County, one of the largest freshwater swamps in the state, to the Shawangunk Mountains, a popular recreational destination with a remarkable array of rare plant and animal species. And throughout the region runs the majestic Hudson River, a water resource of natural and national significance. The region also includes over 200,000 acres of DEC managed state land with campgrounds, wildlife management areas, forest preserve and state forest.
The Region 3 office is located at 21 South Putt Corners Road in New Paltz.
