WORCESTER - The Worcester Redevelopment Authority is poised to move forward on renovations to Union Station to accommodate the new headquarters of the state Cannabis Control Commission.

The WRA board is being asked to authorize an amendment to its design services agreement with Nault Architects Inc., in the amount of $170,000, to provide for renovation of 13,700-square feet of office space on the second floor of Union Station.

The space will be leased to the state Division of Capital Asset Management and Maintenance for offices for the commission.

The WRA board is scheduled to take up the contract amendment at its meeting Friday morning.

DCAMM recently gave "conditional acceptance" to the city's proposal to have the Cannabis Control Commission move its headquarters into Union Station, which was one of 10 sites under consideration in Worcester for the agency.

The commission voted in April to make Worcester its permanent headquarters, with a satellite office in the Boston area.

No formal announcement of the move has been made by DCAMM or the Cannabis Control Commission.

DCAMM is making the decision and handling negotiations for the lease, with input from the commission, according to Michael E. Traynor, the city's chief development officer and executive director of the WRA.

The Cannabis Control Commission is the state agency that oversees the fledgling legal marijuana industry in Massachusetts. It is now housed in temporary offices in Boston's Financial District and its lease there ends in May.

The commission is expected to bring as many as 50 employees to Union Station, and additional foot traffic. It is looking for a 10-year lease. It would become the first state agency to have its main office in Worcester.

The second-floor space in Union Station offered to the Cannabis Control Commission was formerly occupied by the Central Massachusetts Regional Planning Commission and Vanasse Hangen Brustlin Inc., a civil engineering firm. They both moved to other office space in downtown Worcester, and the space is now vacant.

In another Union Station-related matter before the WRA board, Robert "Gus" Giordano, who owns and operates Maxwell-Silverman's Banquet and Conference Center and Luciano's Restaurant at Union Station, is requesting use of the space at the station formerly occupied by Byblos Lounge, later known as the Lava Lounge.

The space is off the east end of the station's Great Hall, opposite where Mr. Giordano has his restaurant. The space has been vacant since July, when the WRA board terminated the lease for the Lava Lounge. The Lava Lounge had received citations for violating provisions of its liquor license, overcrowding and fire safety issues.
