Copies of the Comprehensive Economic Impact study of the proposed massive shopping center on Route 1 that will include a Walmart will be available at the town office and on its website by June 30, according to the town newsletter for July.

The Thomaston Planning Board will hold a public hearing Tuesday, July 19 at 6 p.m. at Watts Hall in which Planning Decisions will provide a summary presentation of the study. The study is required of the large retailer under Maine’s Informed Growth Act.

The presenters will also be able to answer questions at that meeting.

Chief Economist Charles Lawton and Vice President Frank O’Hara of Planning Decisions of Hallowell met with members of the community in March to discuss their plans for the study and gather input from the public.

Greely Associates has proposed a large shopping center on Route 1 next to Dorman’s Dairy Dream and across from Applebee’s. The largest business in the center will be a $28 million, 150,000-square-foot Walmart, if all of the plans are approved.

Because the project is more than 75,000 square feet in size, Maine’s Informed Growth Act requires that a comprehensive economic impact study of the proposed store be completed and submitted to the planning board, which will determine whether the project will have an undue adverse impact.
