Microsoft is proposing a 30-foot sound wall along the north side of its data center under construction in Granger. The company says the barrier could help address neighbors’ concerns about noise and vibrations.

The wall would run alongside the Indiana Toll Road, between Currant Road and Bittersweet Road. County Economic Development Director Bill Schalliol says Microsoft brought forward the proposal after hearing feedback from the community. It would require a zoning variance.

The wall could reduce sound by an estimated 13-and-a-half to 16-and-a-half decibels. It would be visible to drivers on the toll road, but not to nearby neighborhoods. Some residents remain concerned about the data center’s eventual noise, while others say the toll road already creates considerable sound.

The data center is still years from completion. Microsoft’s proposal is scheduled for a St. Joseph County Board of Zoning Appeals hearing Thursday at 1:30 p.m.
