WORCESTER - The License Commission Thursday approved three more licenses for the operation of adult-use marijuana retail stores in the city.

The licenses were granted to: Mayflower Medicinals Inc., 645 Park Ave.; Trichome Health Corp., 64 West Boylston St.; and Mission MA Inc., 640 Lincoln St.

That brings the total number of licenses that have been approved by the License Commission for adult-use marijuana retail stores to five.

The latest three still must receive final approval from the state Cannabis Control Commission before they can open for business.

The city is limiting the number of adult-use marijuana stores to 15 — a figure that is based on 20 percent of the number of off-premises alcohol licenses the city is authorized to issue.

There is no limit on the number of other marijuana-related businesses that do not have points of sale with the public, such as marijuana cultivators, independent testing laboratories, product manufacturers, research facilities, transporters and micro-businesses.

All three businesses have already received special permits from the Planning Board to operate.

Of the three-license requests, the License Commission expressed the most concern about Trichome's proposed storefront at 64 West Boylston St.

Commission Chairman Anthony Salvidio and Commissioner Walter Shea noted that West Boylston Street is a busy traffic area and is especially prone to having backups during the morning and evening rush hours.

"The area is congested to begin with," Mr. Salvidio said. "The Worcester Police Department has concerns about the high traffic volume and number of accidents in that area. We have no problem with what you want to do but you have to be sensitive to the traffic concerns.

"Your facility is fine; your parking is fine," he added. "Our concern is with the traffic; it's a challenging corner. We are looking for solutions. If there are problems, there will be restrictions placed on your license."

Joshua Lee Smith, a lawyer with Bowditch & Dewey representing Trichome Health Corp., said his client is sensitive to the potential traffic issues at that location. For that reason, he said, Trichome has agreed to having a 10 a.m. opening each day, after the morning traffic rush hour.

He added that the peak customer hours for retail marijuana stores tend not to coincide with the peak hours of traffic.

Mr. Smith also pointed out that the proposed storefront is in a commercial zone and it will be located in a multi-tenant building. He said there was also more than enough off-street parking for the business.

He added that there was no opposition to the proposed adult-use marijuana store at meetings that were held with neighborhood residents.

As part of the conditions of the license, the License Commission set the store's hours of operation at 10 a.m. to 10 p.m., Monday through Saturday, and 10 a.m. to 8 p.m. Sunday.

In addition, Trichome will be required to have three paid police detail officers at the site during its first 30 days of operation.

"That should help us mitigate the traffic issue," Mr. Salvidio said. "But if there are problems, we may have to go to appointments only there."

Meanwhile, the License Commission had less of a concern with the two other proposed sites.

Mr. Smith, who also represented the two other license applicants, pointed out that both proposed storefronts are in commercial corridors and both will also be in multi-tenant buildings.

He added that both also have more off-street parking than what is required under the city's zoning ordinance.

For the Mayflower Medicinals retail store at 645 Park Ave, the License Commission set its hours of operation at 9 a.m. to 7 p.m., Monday through Saturday, and 11 a.m. to 7 p.m. Sunday.

It is also requiring that one paid police detail officer be on site during the first 30 days of operations for directing traffic.

Mission MA will have a 6,100-square-foot retail store at 640 Lincoln St., where it also has cultivation and product manufacturing operations

Mr. Smith said the building is in an area that is zoned for limited manufacturing. He said the properties there are mostly industrial uses, though he added there is also some retail and warehouse properties.

He added that parking is not an issue. The site has 298 parking spaces, and of that Mr. Smith said that Mission will have the exclusive right to use 28 spaces.

The License Commission set the hours of operation for that retail store at 10 a.m. to 7 p.m. seven days a week.

It is also requiring that two paid police detail officers be on site during the first 30 days to direct traffic.

"We will continue to look at these as time goes on," Mr. Salvidio said in reference to the conditions set for the adult-use marijuana retail stores. "The problem is that some sites are wonderful with easy access in and easy access out, and some sites are a challenge.

"There isn't one blanket set of rules for everybody," he added. "There can't be given the sensitivity of the traffic flow in some areas."
