A company bought a parcel beside Waterfront Square towers along the Delaware River and plans a residential development at site, the broker who handled the deal announced Monday.

Michael Barmash of Colliers International said in a statement that Pier 35 1/2 - same name as the site - acquired the 2.13-acre tract from SA Group Properties on April 29.

Barmash did not immediately return a phone message regarding pricing details and specifics about the buyer's plans.
