Extending 20 miles from Chappaqua to Yonkers, the Saw Mill River is a major natural resource in Westchester and a critical riparian corridor. It is the County’s southernmost tributary to the Hudson River and provides some of the only remaining habitat in this part of the County for a wide range of plants and animals. The swath of green land around the river is one of the few extended open space corridors below interstate 287, and it is used by thousands of bikers, joggers, rollerbladers, and fishermen.

Years of heavy land use, miles and miles of roadways, and high population density present serious challenges to the river, including flooding, pollution, streambank erosion, habitat loss, and ecosystem degradation. Groundwork Hudson Valley seeks to engage the local community in the restoration of 3 sites along the Saw Mill River. The restoration work includes planting and protecting new native trees, shrubs, and seedlings; seeding new, native grasses; installing deer fences; creating footpaths to open access to the river; placing wood chips as ground cover to protect the seedlings and paths; installing benches; and enhancing signage.

The benefits of the Saw Mill River Habitat Restoration project include enhanced biodiversity, reduced sedimentation, improved habitat for riparian dependent species, improved public access, and community awareness.
