After hearing six hours of back and forth about the plan last week, West Hartford’s town council is expected to decide Wednesday night whether developers can put up a six-story condo building and mixed-used complex in the town center. The decision on The Arapahoe Group’s proposal is certain to disappoint plenty of people regardless of which way the vote goes. Developers consider the land some of the most under-used real estate in town, largely because much of it is a simple parking lot. Arapahoe would put up a six-story building with 58 condominiums along with a five-story building of 25 apartments above a ground-floor restaurant or store. The council will meet Wednesday at 6:30 p.m. at town hall to decide the matter.
