a drive-through window and large parking lot surrounded and intersected with trees. Landscape architect Dan Kiley chose specific types of trees and foliage in order to integrate the bank with its neighboring buildings and help shade the inside of the bank. He used littleleaf linden trees as the basis of the space, with euonymus as ground cover and seasonal spring bulbs, begonias, geraniums, and chrysanthemums as accents. The goal was to create a green space in the middle of downtown Columbus and provide the city with some breathing room. Since the bank building is lower than the surrounding buildings, its landscape feels more park-like. As the number of automobiles on the streets grew in the early 1950s, spaces like this helped relieve the congestion of busy downtown areas. Bank closure On September 18, 2009, the Indiana Department of Financial Institutions closed the Irwin Union Bank and Trust Company and named the Federal Deposit Insurance Corporation (FDIC) as receiver. First Financial Bank of Hamilton, Ohio, purchased all deposits and virtually all assets of Irwin Union Bank and participated in a loss-share transaction jointly with the FDIC. The FDIC estimated that the cost to the Deposit Insurance Fund (DIF) for both institutions was $850 million. Cummins ownership In 2010, Cummins purchased the building from First Financial and announced its intention to remodel the bank and associated buildings at a cost of $5.25 million. First Financial would continue to occupy the building until its new facility is completed in 2012. Cummins then expects to complete renovations by summer 2014. The Saarinen-designed structure will be used for a corporate conference center and meeting space.
