A developer unveiled plans Tuesday to install a Wegmans grocery store as part of a sweeping plan to redevelop Barley Mill Plaza in Greenville. 

Newport developer Gregory Pettinaro, who owns the now defunct DuPont Co. office complex at the intersection of Del. 141 and Lancaster Pike, showed the public plans to build upscale residences, shops and office space along with the grocery store on the 56-acre property.

The project is planned to be 464,844-square-feet and is planned to include retail stores, restaurants, townhomes and apartments, and two office buildings.
