A CVS pharmacy and retail store might be coming to Marion.

A team of design and legal professionals working on behalf of development firm Mark Investments LLC briefed Planning Board members on the project Tuesday night.

Plans call for construction of a 14,600-square-foot building with a drive-thru at the corner of the intersection of Route 6 and Front Street.

“This is a large project,” Chair Stephen Kokkins said. “It’s about two-and-a-half times bigger than the footprint of any recent [commercial] building in Marion, which includes Cumberland Farms and a to be built produce and ice cream stand.”

The spot is located across the street from Cumberland Farms and is zoned for general business.

Now, the historic Captain Hadley House is on the site. To make room for the CVS, developers proposed relocating the 3,900-square-foot building to a parcel adjacent to the site, not far from its current location.

Old Rochester Community Television, an insurance agency and medical offices are Hadley House tenants.

Tuesday marked the first time that Planning Board members and the public had a chance to learn about the project. Plans were shown during an informational session that allowed for comment from the board and public.

Several audience and board members expressed dismay at the project’s size, design and potential traffic woes.

The plans would create 17 parking spaces for Hadley House customers and 65 parking spaces for the CVS. Four access points for traffic would be added along Route 6, one for the Hadley House and three for CVS while one driveway would serve traffic entering from Front Street.

Robert Michaud of the Marlborough-based MDM Transportation Consultants, Inc. presented a traffic study to board members. According to the study, conducted in August, Michaud said there would be little impact to the area.

“I can say with certainty that this is one of the locations in Massachusetts that would work quite well for a project such as this,” he said.

Citing the town’s past experience with summertime congestion at Cumberland Farms, Kokkins disagreed.

“These studies have a way of not taking into account real situations that occur,” he said. For example, they don’t consider the impact that trailers used to haul landscape equipment and boats have.

“Those have proven to be extremely difficult to handle in congested sites,” Kokkins said.

He noted that the board would hire an independent traffic consultant to review MDM’s study if the project moves forward.

Kokkins said the developer should also take into account the town’s zoning code. There are sections that require projects to be built with traffic, safety and conformance to a neighborhood’s character in mind.

“That is in our laws. This is taken seriously by the town and its residents,” Kokkins said.

Other board members noted the CVS seemed super-sized compared to the town’s need.

“I’m just not sure why this CVS is so huge,” board member Michael Popitz said. Popitz and board member Robert Lane asked if CVS corporate could downsize the plans.

Mark Investments representative Dean Holt said that wasn’t possible. The company does have plans for stores that are about 12,000 square feet, but those typically aren’t as profitable as the larger ones.

“This to me is just – wow. It doesn’t feel right and that’s my opinion, but I think it’s also a lot of people’s opinions, too,” member Steve Gonsalves said. “We’ve got to do something about this building.”

He suggested that the developer consider modeling the store’s design similar to a CVS built in Sandwich. After viewing a picture of that store members agreed the design would be a better fit for Marion.

Board members thanked everyone for their comments. Mark Investment officials have not submitted an official proposal for the board to consider.

The next Marion Planning Board meeting is scheduled for Monday, Sept. 15 at 7 p.m. in the Town House.
