Lower Manhattan expansion (original) (raw)

The expansion of the land area of Lower Manhattan in New York City by land reclamation has, over time, greatly altered Manhattan Island's shorelines on the Hudson and East rivers; as well as those of the Upper New York Bay. The extension of the island began with European colonialization and continued in the 20th century. Incremental encroachment as well as major infrastructure have added acreage to the island. Since the passage of the Rivers and Harbors Act of 1899 all projects which extend into navigable waterways follow federal regulation and are overseen by the United States Army Corps of Engineers.
