Stormwater management is fundamental to restoring the health of the Saw Mill River. Stormwater causes recurrent flooding events, and also has a direct impact on water quality, habitat, and public access. Improving stormwater management in the Saw Mill Watershed is even more crucial given the impact of climate change. More and more, extraordinary weather events are becoming the norm in Westchester County. Nor’easters, tropical storms and severe thunderstorms have deluged Westchester with greater frequency and intensity. With intense development throughout the Saw Mill Watershed, and specifically along the Saw Mill River floodplain, permeable surface is becoming rare, resulting in more flooding, bank erosion, low filtration and deterioration of sewer utilities.
