There’s going to be about 16 more acres to the center of the city if the City Council approves a change in zoning for four parcels in August.

And not only is a change of zoning in the offing, but the prospect of more developments on Jefferson Boulevard in the vicinity of the InterLink, according to Mayor Scott Avedisian. Avedisian is silent on the development, but land directly across Kilvert Street from the Iron Works Tavern and the site of the former Elizabeth Mills, two of the parcels under consideration for a rezoning, are thought to be sites for the latest projects.

Should the rezoning be approved – it gained approval of the Planning Board earlier this month – City Centre zoning would be expanded to include what is now D’Ambra Construction offices and asphalt plant; the former Leviton Manufacturing and Elizabeth Mill property owned by developer Michael Integlia; an L-shaped parcel bordering the Honey Dew donut and coffee shop at the intersection of Coronado Street and Jefferson Boulevard and a T-shaped combination of lots across Jefferson Boulevard from Honey Dew.

The zoning of the four parcels would be changed from a combination of light industrial, residential and general business to Intermodal and would be consistent with implementation of the Comprehensive Plan and the City Centre Warwick Master Plan, according to the Planning Department.

In its overview to the Planning Board, the master plan provides the framework for the development of up to 1.5 million square feet of office, retail, hotel and residential development in the core of the Intermodal area, which is now 37 acres. An additional development of 1 to 2 million square feet is envisioned to eventually occur in the surrounding areas.

While the area, a confluence of highway, rail and air transportation, has long been thought as prime for development, projects have been slow in evolving from the drawing board to concrete and steel. The first was the Hampton Garden Inn built on the site of the former Malleable Iron complex by Joseph Piscopio. Piscopio preserved the office building to the plant and later converted it into the Iron Works Tavern.

With the development of the InterLink, construction of the rental car garage and commuter rail platform with service from the MBTA, it was imagined additional developments would happen.

There have been plenty of ideas.

Michael D’Ambra of D’Ambra Construction drafted plans and gained city approvals to convert the long rectangular lot running south from the InterLink garage to the Airport Connector into a multi-faceted development including a hotel, parking garage, office towers and limited retail space.

Then more recently, Integlia worked out a deal to acquire the 80-acre former Leviton manufacturing property across from D’Ambra on Jefferson Boulevard. He split the property up, selling much of the massive Leviton building to Dean Warehousing; designating about 30 acres of wetlands and property requiring environmental cleanup if developed as open space; creating a buildable lot on Metro Boulevard, which has been cleared; and two other lots. One of those parcels was the site of the Elizabeth Mill built in 1875 that the city hoped to preserve as an icon of Warwick’s industrial roots. Integlia sought to re-purpose the mill with its bell tower as offices or residential, but after about a year came up with a plan to demolish the mill and build a mixed use of office and retail on the property.

While parcels across from Iron Works Tavern are considered to be imminent for development, the Planning Department looked at the entire area, concluding it made sense to include the three other parcels in the rezoning rather than doing it piecemeal as potential projects were proposed.

The City Council is scheduled to consider the rezoning for first passage at a public hearing on Aug. 12.
