MACHIAS, Maine — Dollar Tree officials are hoping the store proposed for 86 Dublin St. will open in May.

“Obviously, it could be a little earlier or a little later,” said Shelley Davis, spokeswoman for the chain, which is headquartered in Chesapeake, Virginia.

Davis said Wednesday that Dollar Tree expects to hire 12 to 15 permanent part-time workers and one or two full-time managers for the store. The company also will hire seasonal help as needed.

Dean Associates Architectural and Interior Design of Wakefield, Massachusetts, filed a building permit application with the local planning board on Dollar Tree’s behalf Nov. 6. The planning board approved the proposal at its meeting Dec. 2.

James Dean of Dean Associates told the members of the planning board that he estimates renovations will take six weeks. The store will need another week and a half to stock before opening, according to planning board minutes.

Davis said she did not know when work would begin.

“The scope of work will be primarily interior in nature, no expansion of the building footprint is proposed,” the application states.

The project is estimated to cost $140,000, according to the application.

Davis confirmed Dollar Tree has leased the building for five years with an option to renew for another five years and then another five years after that.

The building has been unoccupied since 2007 when Rite Aid moved to its current location next door.
