DARIEN — The Darien Planning and Zoning Commission voted on Tuesday night to approve the site plan for the Commons at Noroton Heights, Federal Realty’s plan to redevelop the eastern portion of the Noroton Heights Shopping Center.

According to Planning and Zoning Chairman, the group voted unanimously in favor of the project, which includes plans to build three new buildings with 122 residential units — 67 one-bedroom, 55 two-bedroom — with first-floor commercial space. The current Stop and Shop and Walgreens will be razed to accommodate the project.

Federal debuted their plans for the area in 2015, and since the project has gone through a lengthy approval process.

“I think we as a commission addressed this pretty exhaustively,” Sini said at the group’s August meeting.
