NYC Flood Exposure by Sewershed
Most of New York City drains to a combined sewer, and every property shares its pipe with thousands of neighbors. A sewershed is the area that drains to one combined sewer overflow outfall, as mapped by NYC DEP. When rain overwhelms that pipe, the whole sewershed feels it, which makes it the right scale for understanding sewer backup and stormwater exposure on your block.
