In 2012 and 2013, GRA was contracted to conduct monitoring and Phase I and II survey for a development on the Upper West Side of Manhattan.
The property lies on the long-buried former bank of the Hudson River. GRA has documented the prehistoric surface of the island, waterfront posts within a small harbor dating to the first half of the 19th century, and 10,000 household artifacts pre-dating the turn of the century. GRA also documented a well-preserved stockyard pavement which was constructed in the last quarter of the 19th century, traces of the original Hudson River Railroad, the corner of a small stone building foundation, and a well. We are reconstructing the built and natural features of the local landscape in three dimensions, in order to analyze and illustrate the growth of the city over time.
GRA is presently in the final stages of analysis and reporting for this project.
