Pettinaro to Provide Barley Mill Update at Wednesday Meeting

Greg Pettinaro will discuss next steps for the highly anticipated redevelopment of Barley Mill Plaza at a community meeting on Wednesday night

The developer who plans to bring a Wegmans grocery store to Barley Mill Plaza will update the community on construction plans, traffic issues and next steps related to the site at a public meeting Wednesday night.

Greg Pettinaro, CEO of Pettinaro, said that DelDOT had recently completed a traffic study that he will share at the meeting on Wednesday, September 25th at A.I. duPont High School (50 Hillside Road in Wilmington) at 7 pm.


Pettinaro said a completed traffic study indicated that three major intersections around the Barley Mill site – 141/48, 141/Barley Mill Road and 141/Montchanin Road – are already considered by DelDOT to be “failing” (according to wait times at traffic lights). However, Pettinaro says the mixed-use plans for the site will actually alleviate some traffic issues, by distributing car movement in and out of the site at various times of day rather than just the early morning and pre-dinner rush hours.

In order for his project to move forward, Pettinaro will seek a traffic waiver from New Castle County Council, which meets on October 22nd.

This is a new site plan for the Barley Mill Plaza development. Greg Pettinaro will discuss the slight changes between this plan and his initial plan at the meeting on Wednesday night.

“We’re hoping a traffic waiver will allow us to build our property without major improvements to the intersections,” said Pettinaro. “DelDOT is not recommending major improvements because those improvements would be out of character to the area – a flyover over 141 or widening it into the open space and making it four lanes – those kids of improvements, which would be out of character for the neighborhood.”

Pettinaro told us that since the last community meeting regarding the project, the company has received its Board of Adjustment approval.

He plans to also update the community on construction efforts to salvage some of the buildings at the current site. Many were gutted in an attempt to renovate some of the buildings. Once they are demolished, Pettinaro says the materials will be recycled.


“We spent about six months trying to refurbish them and we just couldn’t do it. There just isn’t enough interest in the existing layouts and low ceiling office suites,” he said.

Pettinaro also said they plan to unveil “minor” design changes to the 500,000 square foot proposal first unveiled in February, including building elevations, walking paths and possible new layouts surrounding the retail and residential communities. Small facade changes to the townhomes may also be shared. The changes were based on feedback from community members and the New Castle County Department of Land Use.

The height restriction at the site is 50 feet. But Pettinato says they will come in under that. The site will include:
• 33 townhouses
• 80 four-story flats
• 152,200 sq. ft. of retail in two shopping strips with restaurants, shops, and a coffee shop
• 161,000 square feet of office space
• 11 acres of green space

Wegmans will anchor the new Barley Mill Plaza site

If Pettinaro receives approvals in February, then they would break ground in the spring of 2020 and turn over the pad site to Wegmans in the spring of 2021. Wegmans would open in the spring of 2022.

Pettinaro’s February presentation to a full house at the Greenville high school was favorably received by an audience that included many residents who had vocally opposed the initial plans for a 2.8 million square foot colossus proposed by another developer.  

Attendees cheered the news the upscale grocer Wegmans had agreed to build a store, along with Pettinaro’s description of townhouses and retailers that will inhabit the firmer DuPont Company campus.

  • 141 and Lancaster Pike should be grade separated with ramps. Otherwise congestion like the 202 and RT 1 PA crossing will occur. If the intersection is failing now, I don t know how the argument that this development, because of its nature of the development will eliminate this issue. Further the “ramps being out of character for the area” is an inappropriate suggestion: by the nature of building a high density project, you have already changed the character.

  • I like your idea of ramps in the long term; and to clarify, I think Pettinaro was referring to the “flyover” as being out of character, not ramps. As for the project changing the character of the area, I agree with you there, as well. However, I believe the character will actually be improved, as a grim, deteriorating business park is transformed into something vibrant and useful.
