UNION, Maine — A national discount store that has been trying for a year to enter the Knox County market has now set its sights on this rural town.

An application to build a Dollar General Store at the intersection of Route 17 and Townhouse Road was filed Wednesday with Union by Nobis Engineering from Concord, N.H.

The town planning board will hold a pre-application meeting on the proposal on Nov. 10. The meeting will start at 6:30 p.m. in the rear meeting room of the town office.

The proposal calls for a 9,100-square-foot store.

Code Enforcement Officer Grant Watmough said the site plan review process will take multiple meetings. The property is zoned commercial, the code officer said.

Dollar General has 12,500 stores in 43 states, according to its website.

Dollar General has tried to locate a store in two other nearby Knox County towns. In February, Dollar General approached Thomaston about building a store on the Thomaston Green on Route 1. The proposal was rejected because it failed to meet the town’s design standards.

Citizens gathered petitions and there will be a referendum to limit the size of stores in that area of town to a maximum of 2,500 square feet. A special town meeting to approve that zone change is set for 7 p.m. Nov. 21.

After being rebuffed by Thomaston, Dollar General proposed in September building a store in Warren at the intersection of the Manktown Road near the Waldoboro townline. This site is about 6 miles south of the Thomaston property.

Code Officer Melody Sainio said that Dollar General then considered two other sites in Warren, both also on Route 1 — one near Ande’s Variety and the other across from the Maritime Farms store.

Sainio said Thursday that she was in contact with the developer two weeks ago and was told the company was not interested in being put on the October agenda.
