ST. LOUIS (AP) — St. Louis could be the next city to raise its minimum wage significantly if Mayor Francis Slay has his way.

Slay spokeswoman Maggie Crane on Tuesday confirmed that the Democratic mayor wants to raise the city’s minimum. She says a starting point for discussion is $15 per hour by Jan. 1, 2020, but details are still being ironed out.

Alderman Shane Cohn is expected to file a formal bill Friday.

The federal minimum wage has remained at $7.25 since 2009, prompting some cities like Seattle, Chicago and San Francisco to raise the standard on their own.

Missouri lawmakers last month passed a bill stripping cities’ ability to adopt local policies, including a local minimum wage. But cities with a different minimum wage in place before Aug. 28 would be exempt.
