The Decatur Main Street Program is an economic development and physical  improvement process designed to benefit the historic central business district. The overall goal is to bring and circulate commerce in downtown Decatur. Key functions are aiding present businesses to be more successful, improving the physical attractiveness of the downtown area, and recruiting new business.

The Main Street Advisory Board has been appointed by the City Council to oversee the project. The Main Street Manager, employed by the City, coordinates the directives of the City and Main Street Advisory Board.   A volunteer organization, the Main Street Advisory Board oversees the program with committees focusing on Promotions, History, Economic Restructuring, and Merchant issues. Now in it's 15th year, the program is work in progress with many success stories to tell and many yet to come.

The Main Street approach is a comprehensive process which initiates positive steps to revitalize and maintain a healthy downtown business district.
