Mayor Thad Birmingham has decided to not sign the agreement between the city and the Sturgeon Bay Historical Society for the Teweles and Brandeis grain elevator.  According to Common Council President Kelly Catarozoli, she talked with City Administrator Josh Van Lieshout and a League of Municipalities attorney on Thursday to confirm that the contract that was approved by the council and upheld by overturning the mayor’s veto is binding.  Christie Weber, president of the Sturgeon Bay Historical Society, says according to the city attorney, Birmingham’s signature is not necessarily affecting the agreement between the two parties that gives the city ownership of the granary.  Birmingham’s tenure as mayor ends in the coming days as David Ward will be sworn in with four new council members at City Hall on Friday and take their respective seats on the common council next Tuesday.  Van Lieshout could not be reached for comment on Thursday.
