Alamo Plaza redevelopment project gets new leadership to move forward Nirenberg asked Councilman Robert Trevino to resign from his role on the committee on Monday Tags: SAN ANTONIO – Plans to redevelop the Alamo Plaza must move forward with a new design and leadership team, according to an announcement by San Antonio Mayor Ron Nirenberg. Nirenberg said he needed a leader that is on board with changes to the project and announced the removal of District 1 Councilman Roberto Trevino as the lead person in the committee. “The position that Councilman Trevino has taken, which is that the Cenotaph can’t move -- then the Alamo Plan is dead, is not tenable. It’s not gonna move,” Nirenberg said.
