BURRILLVILLE — The old clock tower, a focal point in the planned revitalization of the Stillwater Mill site, is ready for construction, the town manager told the Town Council last night.

The Burrillville Redevelopment Agency has transferred the building to Neighborworks Blackstone River Valley Alliance, which will oversee the renovation of the site.

The transaction was one of the agency’s final tasks in an overall effort to prepare the Harrisville site for mixed-income and elderly housing. The project, which includes the town’s newly completed library building, has been in the works for years.

The clock tower is regarded as one of the site’s greatest architectural assets.

Town Manager Michael C. Wood told the council that the sale of the mill building means that construction on the tower might begin within six months.

“It’s been long overdue, long-awaited,” said the council’s president, Nancy Binns. “We’re delighted it’s finally taken place.”

In other business last night, the council took the step of declaring three local roads as “public highways.”

The town’s work crews have made some effort to maintain the three roads — Shady Lane, Maple Terrace and Highland Road — for at least 20 years.

They plowed snow from the roads and filled potholes to enhance the accessibility of the roads for public safety purposes.

But the town needs to take ownership of the public ways to make any additional improvements officials said last night.

The council also voted to proclaim the month of July as Cigarette Litter Prevention Month as a way of supporting the Recreation Department’s summer-long campaign to keep Spring Lake Beach free of cigarette butts.

The council reappointed Mark Brizard to the town’s Budget Board for a three-year term and appointed Barbara Schouboe as an alternate member of the Redevelopment Agency.

The council also awarded a $150,000 bid for design work for the renovation and expansion of the police station to Saccoccio & Associates.
