The Batavia School Board will be voting on its 2020 (payable 2021) tax levy Tuesday night, 11/17, 7pm. Agenda here: https://go.boarddocs.com/il/bps101/Board.nsf/Public. 
As usual, they will be increasing taxes by the maximum allowed by law, so your property taxes will be going up. From the agenda:

You can and should let your thoughts be known to the Board, at the meeting or using the button at right to email, but don’t expect it to make a difference. The only thing that could stop the incessant tax increases would be a new School Board.

If you would like to run for School Board (or any other office), petitions can be circulated now. Filing dates are Dec. 14-21.
