New York City is considering extending Manhattan island two and a half miles south into the New York Harbor with reclaimed land, forming a new neighborhood called New Mannahatta. Based on the Upper West Side, the new neighborhood would have 178 thousand housing units for 247 thousand people. It would have parks, bike and pedestrian paths and subway line extensions for routes 1 and G, helping integrate it with the rest of the city. It would also be elevated and surrounded with wetlands, helping protect against storm surges. While it would provide more housing supply, protect against climate change and generate massive real estate value, it would cost billions of dollars, take decades to complete and increase traffic in the city.
