The measure before the commission would create a five-member authority that would write the ballot question. The DIA is seeking a point-two mill tax increase in Wayne, Oakland and Macomb counties.
The millage would cost the owner of a $200,000 home $20 a year.
If all three counties approve it, the tax would raise $23 million for the museum. The money would pay for operations. The DIA is promising free admission to residents is counties that approve the millage.
Commissioners in Wayne and Macomb counties have already voted to create the authority.
*Correction: An earlier version of this story incorrectly stated that commissioners in Wayne and Oakland counties had voted to put the millage question on the ballot. Wayne and Macomb have done that; Oakland commissioners vote this week. Also, the money raised by the millage would pay for operations, not an operations endowment. The copy above has been corrected.
