ORANGE — The town’s Economic Development & Industrial Corporation is seeking qualified developers for the potential purchase and redevelopment of the former Butterfield School at 94 South Main St. The Request for Interest, issued last week, invites individuals and organizations to submit conceptual proposals for the 2.21-acre site, which includes the 37,533-square-foot former school building built in 1878. Senior housing is a potential reuse. It kind of determined there were three potential reuses — town hall or offices, a senior center or senior housing. The former Butterfield School closed in 2015 due to declining enrollment and to help alleviate the town’s financial woes.
