Piermont Marsh encompasses 1,017 acres and lies at the southern edge of the village of Piermont, four miles south of Nyack in Rockland County. The Piermont Marsh is on the western shore of the Tappan Zee. The site occupies two miles of shoreline south of the mile-long Piermont Pier and includes the mouth of Sparkill Creek and extensive tidal shallows. Piermont Marsh habitats include brackish tidal marsh, shallows and intertidal flats. The Sparkill Creek drains 11.1 square miles of watershed. There is a picnic area on Paradise Avenue in Piermont. Nearby, Tallman Mountain State Park offers many recreational opportunities.

A new Draft Piermont Marsh Reserve Management Plan (PDF, 4.43 MB) is available for public review. It will guide marsh management, habitat restoration, resource stewardship, public access, education programs, and research at the Piermont Marsh Reserve for the next decade.

The adoption of the Piermont Marsh Reserve Management Plan is classified as a Type I action under the State Environmental Quality Review Act (SEQR). NYSDEC, as lead agency, has performed a coordinated review and determined (PDF, 211 KB) that the adoption of the draft plan will not result in a significant adverse environmental impact.
