Chemung Canal to relocate from the Ithaca Commons

(Elmira, NY) Chemung Canal Trust Company (CCTC) is announcing it will be relocating its office from the Ithaca Commons, effective May 31, 2016.

“For more than a year, we have been in lease negotiations with the landlord of our Commons office,” said Anders M. Tomson, President & Chief Operating Officer of Chemung Canal Trust Company, “unfortunately, we were just not able to reach mutually acceptable terms for our continued occupancy.”

“We had been in discussions with the landlord about redesigning the branch into something that met our requirements and allowed us to more efficiently serve the needs of our clients,” Tomson said. “Given the changing environment of banking – where less clients are “in the branch” and more clients are utilizing technology (desktops, tablets, smart phones, etc.) – the need for square footage is not nearly as significant as in previous decades,” he added.

The Commons branch is more than 12,000 square feet, spread out over three levels. Chemung Canal took possession of the office in November 2013, when it purchased the branch (along with a branch at 304 Elmira Rd. in Ithaca) from Bank of America. The lease expired on December 31, 2015.

“While the banking location for some of our clients is changing, the one thing that will not change is our commitment to provide a full menu of products and services, delivered by well-trained, highly qualified banking professionals,” Tomson said. Despite the relocation, the bank announced there will be no reduction in staffing levels, with existing employees being redeployed to CCTC’s three remaining Ithaca offices.

Chemung Canal Trust Company’s other Ithaca offices are located at: 806 West Buffalo Street (The Station), 304 Elmira Road and 909 Hanshaw Rd (Community Corners). The Elmira Road and Buffalo Street branches are less than a mile away from the Commons office. Clients will not be required to do anything to transfer their accounts to other branches.

“We are pleased to report that our three other Ithaca offices feature longer hours than were available at the Commons, and we are open on Saturdays at Elmira Road and Community

Corners,” Tomson said. Additionally each Ithaca office has a drive-up teller, a fully functional (24/7) drive-up ATM – which accepts cash and check deposits, in addition to cash withdrawals, balance inquiries and account transfers. Each branch has ample parking.
