ATTLEBORO -- A request to rezone more than half of the Attleboro Corporate Campus to make way for hundreds of condominiums has been flatly rejected by the planning board, which could spell doom for the plan when it reaches the city council floor -- possibly next month.

The board unanimously urged the council to deny the rezoning because it would diminish industrial acreage in the face of Attleboro's long-held policy to maintain or expand its industrial base.

Planners also found that campus owner, Preferred Real Estate Investments, failed to adequately market the property, formerly owned by Texas Instruments, before deciding to use it for homes, rather than businesses.

The planning board was the second major board to come out against the plan. The Attleboro Redevelopment Authority previously voted to recommend denial because of the loss of industrial land.

The council, which has the final say, has yet to vote, but members raised serious concerns about the plan at a long and contentious hearing last month. While Preferred argued the new residential units would result in a net gain of tax revenue for the city's general fund, councilors didn't buy it, asserting the rezoning would stress city services and add costs.

Concerns about traffic were also raised, with one councilor demanding major improvements to Pleasant Street if the rezoning was to go forward.

And like the planning board, councilors raised worries about the a decline in industrial property.

Preferred is revamping the remainder of the 261-acre campus and its buildings for industrial uses and has completed deals for at least three companies, so far.

At the hearing, a spokesman said homes on the campus would make the industrial property more attractive to prospective tenants or buyers.

The residential plans call for the construction of 324 condominiums, some of which would be townhouses, on 142 acres of the campus.

To accomplish the goal, the city would see a net loss of 21.6 acres of industrial land. A total of 24.3 acres would be rezoned from industrial to general residence under the plan.

All told, 139.4 acres would be rezoned to general residence to accommodate the condominiums. Of that amount, about 118 acres are already zoned for single residence use, but a designation of general residence is needed for the condominiums.

Approximately 2.8 acres would be rezoned from single residential to industrial.

Zoning and Land Use Committee Chairman Robert Schoch said the matter will likely be discussed at the panel's July meeting, and a vote is possible. Preferred's attorney, Jack Jacobi, declined comment because he had not read the planning board's decision. The company's marketing director, Miguel Pena, did not immediately return a call.
