PORTLAND — Officials in Maine’s largest city are reviewing a proposal to increase the minimum wage from $7.50 an hour to $10.68 an hour over the next two years.

The Portland Press Herald reported a Portland City Council committee began reviewing Mayor Michael Brennan’s plan on Thursday. The process of reviewing the law will likely take until at least November.

Brennan wants to bump the city’s minimum wage in steps, from $7.50 to $9.50 an hour on Jan. 1 and then to $10.10 an hour in 2016 and $10.68 an hour in 2017. The wage would then rise every year through cost-of-living adjustments.

The proposal could make Portland Maine’s first city to enact a local wage increase. Some local business owners say the hike is too dramatic.
