In exchange for this sliver of sidewalk, public records show, the developers of 180 Water Street received permission to build nearly 47,000 square feet of office space that would not have otherwise been permitted by zoning. Multiply each of those square feet by the current asking price — which we calculate at about $455 per square foot — and the value of privately owned public spaces to property owners comes into sharp focus.
