ITAMCO's Plymouth Innovation Bid Faces a Notre Dame Clock Colfax Corner Already Started

Indiana Tool & Manufacturing Co., the Plymouth gear and precision-machining manufacturer founded in 1955, announced Oct. 10 that it will petition the City of Plymouth to annex its Michigan Road headquarters and rezone the site, the first step toward an adjacent Indiana Innovation Center and District built around advanced manufacturing, cybersecurity, and tech commercialization. President Gary Neidig said the goal is to connect Plymouth and Marshall County to the University of Notre Dame. Mayor Robert Listenberger and Council President Don Ecker Jr. both endorsed the petitions. No dollar figure or job count has been attached yet.

The complication is timing. South Bend's Colfax Corner, a 202,000-square-foot hub backed by a $30 million Lilly Endowment grant, broke ground weeks before ITAMCO's announcement and already has Notre Dame's iNDustry Labs committed through 2028. Indiana's Innovation Development District statute lets South Bend capture incremental tax revenue for up to 30 years to fund that project, so Plymouth is racing a financing clock and an attention clock at the same time, not just a zoning process.
