Tronconi Segarra & Associates, an accounting and business consulting firm, is proposing a $4.6 million office building in Clarence where it would combine many of its operations.

Tronconi Segarra would team up with McGuire Development on creating a 20,000-square-foot building at 8321 Main St., between Transit and Harris Hill roads.

Tronconi Segarra was founded in 1985 and has offices in Amherst, Clarence and Niagara Falls. If the new building is developed, Tronconi Segarra would combine its Amherst and Clarence operations into that location, but it would continue to operate its Niagara Falls office, said James Dentinger, president of McGuire Development,

In documents filed with the Clarence Industrial Development Agency, Tronconi Segarra said the facility would help create more than 50 jobs in the next five years, as well as retain 86 employees who are currently based in Buffalo Niagara.

“A major part of this project is expansion and more efficient use of space,” Dentinger said.

Tronconi Segarra said it has conducted a nationwide search over the past three years for the “most economically viable location for its headquarters.” The firm said its business has grown to serve clients in more than 30 states and that its professionals frequently travel to perform audit work, tax and financial consulting, business management and strategic planning for its corporate clients.

In 2011, Tronconi Segarra acquired Domachowski, Kempisty & Salvatore, an all-woman accounting firm in Clarence.

If the new office building goes forward, plans call for demolishing a home on the 2.3-acre property. The project is contingent on receiving approval from the town and securing financial assistance from the Clarence IDA, Dentinger said. The agency’s board members were briefed on the project Thursday; a public hearing is expected to be scheduled for the Clarence IDA’s April 18 meeting.

In other business Thursday, the Clarence IDA:

• Decided to stop paying – at least for now – the Coalition for Community Building, which advocates on behalf of area IDAs in Albany. The Clarence IDA’s most recent agreement with the CCB, at a rate of $500 a month, expired in December. The agency paid the CCB for January but has not made a monthly payment since then. The Clarence IDA said it will discuss whether to revive its connection with the CCB when the agency has its strategic planning session this spring.

• Agreed to lease an office, for $350 per month, at the Clarence Chamber of Commerce’s location on Main Street, primarily for use by its economic development officer, Jim Rash. The agreement includes receptionist services and use of a conference media room.
