At its meeting on Tuesday, the Rochester City Council will talk about a potential casino sportsbook. Local voters will be able to cast ballots on the idea in November if it is ultimately approved. The suggestion will only be heard once at the meeting on Tuesday. The referendum would need to be approved in September by the City Council. Before it could be put on the ballot in November, there would also need to be a public hearing in October. On November 7, a referendum including the entire community would be held.
