We often think of the street grid as New York’s greatest “master plan.” Officially known as the Commissioners’ Plan of 1811, this put in place the original, gridded street pattern that we still know today. But there have been several other master plans that took shape on a smaller scale within the linear configuration of Manhattan. These planned communities were largely conceived to transform blighted or underutilized areas into suburban enclaves or peaceful oases within the big city. And just like the neighborhoods that grew organically among the street grid, these master-planned areas each have a unique character. They’ve also influenced a new crop of developments, currently under construction on the West Side and in Brooklyn.
