From the Washington County Insider:

November 4, 2019 – West Bend, WI – West Bend Common Council has unanimously voted to appoint Council President Steve Hoogester as acting mayor until the April 7, 2020 election.

According to City Attorney Ian Prust, said Hoogester can still retain his seat as District 6 alderman and he does not have to run for council again just by taking this post.

Prust said, should there be a tie vote on an issue, Hoogester has to notify the council ahead of time that he will abstain as alderman to make a vote as mayor.

City administrator Jay Shambeau and Prust said a tie situation would be extremely rare as a council member would need to be absent to create a situation for a tie vote to occur.

This seems like a good way to address the issue.
