TAUNTON — There’s a battle brewing in Westville over a proposed retail marijuana shop on the west end of Winthrop Street/Route 44.

A letter from the Greater Westville Neighborhood Association to the Taunton City Council argues against granting a special permit for a retail pot shop at 400 Winthrop St.

A convenience store with a beer and wine license called 44 Express in recent years has been doing business at the location.

The city council so far has granted three special permits to retail-oriented marijuana businesses — all of which must get state approvals and then a local license in order to open for business.

Taunton has set a limit of five as the number of retail pot shops that eventually will be allowed within city limits.

There are now three retail marijuana special-permit applications pending for a .7-mile stretch of Route 44.

The letter from the association posits that a marijuana shop at 400 Winthrop St. would exacerbate an area that already has its share of serious traffic congestion.

It cites the installation of traffic lights this past year next to a new gas station and convenience store — which now includes a Dunkin’ inside the building — at the corner of North Walker and Winthrop streets, directly across from 400 Winthrop St.

Traffic traveling west on 44 during peak hours sometimes backs up as far as a quarter mile, the letter claims.

The letter — which describes Westville as “a mix of residential neighborhoods, an elementary school and several businesses” — claims that a traffic study commissioned by the applicant was conducted before the new convenience store and gas station opened.

The letter also argues that 11 of the 23 parking spaces being proposed to accommodate the 2,100-square-foot marijuana store will be reserved for employees.

City council member Barry Sanders, who previously voted in favor of the three special permits that so far have been granted, would not say how he would vote Tuesday night.

Sanders said he’s received a number of emails from constituents who are concerned about the proposal for 400 Winthrop St., which he said is not particularly surprising considering the issue at hand.

He did, however, say he doesn’t object to the idea of a retail pot shop replacing a liquor store or convenience store that sells beer and wine.

“I’m not a big marijuana guy,” Sanders said. “I don’t touch the stuff and am not interested in it, but in terms of social impact it has a much lower negative effect than alcohol.”

Peter Cullen, who owns the 400 Winthrop St. parcel, said he doesn’t think the retail marijuana shop will worsen traffic conditions.

“Any time you have a daily rush hour you have backups. It just happens, and it’s normal. It’s called gentrification,” he said.

Cullen, who also owns an adjacent parcel at 403 Winthrop St., where a Dunkin’ used to operate, says the number of parking spaces at 400 Winthrop St. will total 30, not 23 — which he said is twice the required number of spaces for a building of that size.

“If you put a Family Dollar there you would have twice the traffic, and no one would say anything,” said Cullen, who added that “I’m trying to help myself as a landlord and get a little more rent.”

Cullen said the applicant, Fairhaven-based Bask Inc., has a proven track record in the legal marijuana industry.

“The end user,” he said, referring to Bask, “will pass the litmus test.”

Bask Inc. already operates a medical marijuana facility in Fairhaven.

In addition to Taunton, the company is trying to establish cultivation and processing facilities in Freetown and a retail shop in Fairhaven.

Cullen, who is trying to sell the site of the former standalone Dunkin’, said the city will collect as much as $400,000 in taxes and revenue from the 400 Winthrop St. pot shop if it eventually opens for business.

Sanders said if the matter comes to a vote Tuesday night he will consider the inherent basis of a special permit.

“It really is about suitability of location,” he said.
