A public hearing about the proposed expansion of the Edgartown Stop & Shop store is slated to begin Thursday before the Martha’s Vineyard Commission.

The project will be reviewed as development of regional impact. The hearing is scheduled to begin at 6 p.m. at the Edgartown library.

Stop & Shop’s proposal calls for constructing a 15,952-square foot addition to the existing 25,000-square-foot supermarket on Upper Main street. An Edgartown National Bank branch next to the Stop & Shop would be demolished and reconstructed elsewhere on the property. The project includes reconfiguring the existing parking lot, adding parking spaces, and changing the location of one of the driveways exiting the property.

Plans also include renovating the existing store, which was built in 1965 as an A&P supermarket. The company plans to move the pharmacy now located at the Triangle to inside the store and add improvements including more check-out stations.

The company’s plans first came before the Edgartown planning board nearly two years ago. In a slightly changed process, review began at the town level with several hearings before the planning board. The project was sent to the commission in January of this year.

During public hearings before the planning board, residents and abutters raised concerns about noise and traffic in the Upper Main street area, a notoriously congested spot during summer months.

If permits are in place, construction could begin in the spring of 2018 with a goal of opening in 2019, according to documents filed with the Martha’s Vineyard Commission. The store would remain open during construction.
