Developer finalizes $160M purchase of U.S. Steel site in Falls Closing on its reported $160 million purchase of more than 1,800 acres of the U.S. Steel site in Falls puts NorthPoint Development a step closer to its planned $1.5 billion transformation of the property. Northpoint plans to build 10 million square feet, and possibly more, of state-of-the-art warehousing on the property in phases over the next several years. Possible tenants include Amazon, Walmart, Chewy and others. Officials from the developer could not be reached for comment, but Falls supervisors Chairman Jeff Dence said he's looking forward to watching the redevelopment take shape now that the purchase went to settlement.
