A state juvenile residential treatment center that has been shuttered for over a decade on a property eyed by town officials as a potential source of tax revenue could finally be repurposed as Hamden seeks a developer for the 50-acre site. Officials have floated ideas such as constructing senior housing or a biomedical campus at High Meadows, but its future has been up in the air for years. The town now hopes to have a plan in place by the spring. To help identify interested parties, the town has issued a request for proposals for a consultant to market the site to potential developers. The position is known as an owners representative, according to a copy of the RFP available online. Hamden aims to start an engagement process in October, issue an RFP to developers that would be due at the start of 2023 and bring a proposal to the Legislative Council in the spring “with an anticipation that we’re going to close on the property with a developer and the state by June 30 of 2023,” Johnson said.
