Lake Worth Beach is looking for a new city manager. Michael Bornstein, who has held the position for nine years, announced his resignation during the City Commission’s meeting Tuesday night. Bornstein’s decision follows a turbulent year in city government, marked by a shouting match between the former mayor and a former city commissioner that went viral. He was closely aligned with that mayor and two city commissioners who lost their bids for re-election in March. Bornstein will remain in office for another 60 days, and the city hopes to name a replacement before he leaves.
