KILLINGLY — State, local and community leaders this month got an up-close look at new Killingly apartment complex that offers a mix of market-value and subsidized housing on a former brownfields property where a dilapidated mill once sat.

On Tuesday, U.S. Congressman Joe Courtney, Killingly town officials and representatives from United Services and The Women’s Institute — both which played oversized roles in the reuse of the Maple Street property — toured The Mills at Killingly Apartments just weeks after more than two dozens tenants moved in.

The three-story brick-and-white-trim complex is overseen by the Demarco Management Corp. with supportive services provided to live-in clients by two United Services workers.

For more than 180 years, the Danielson skyline was dominated by the looming Powdrell & Alexander Mill until age, weather and lack of maintenance led to being deemed unsafe in 2009.

In 2013, the property was bought by The Women’s Institute Realty of Connecticut and, with roughly $14 million in state money, most of the mill was razed and the new complex erected.

“This is an example of a property being brought back to life,” Courtney said. “It’s a great achievement with a mix of occupants.”

Wanda Purcell, of Demarco, said all 25 of the subsidized apartments have been filled, though none of the seven market-value units has yet been rented. The available apartments are renting for approximately $1,400 a month, utilities included.

The tour group walked through unoccupied one-bedroom units with high ceilings, lots of closets and new appliances. A stair tower original to the former mill was rehabbed into apartments with large picture windows.

Ines Mennes, one of the case managers assigned to the complex, said her office provides a host of supportive services for tenants, some of whom she said have never lived on their own.

“We help with socialization, like how to make medical appointments, with mental health and substance abuse issue and even how to do laundry,” she said. “Some tenants will need guidance on cooking or grocery shopping, while others don’t use any of our services.”

Diane Manning, president and chief executive officer for United Services, said the property’s transformation is a tribute to Killingly’s history and location.

“The design fits here and this rejuvenation was possible only with the support of the town and its residents,” she said.

Manning said the tenants granted subsidized apartments were chosen through the Coordinated Access group, a coalition dedicated to curbing homelessness in the state.

Killingly Community Development Administrator Mary Bromm, who helped get the project off the ground, said the journey from run-down mill to new apartments was a long and complex one.

“But now we have a clean-up brownfield property with a new building that is housing low- and moderate-income families who desperately needed housing,” she said.
