Columbus Zoo board discusses transparency, changes amid investigations The Columbus Zoo and Aquarium’s board of directors said they’re working with elected officials to provide transparency about tax levy spending and considering changes to how the board operates. That includes examining terms and "selection criteria," as well as how the board's chairs and assignments are decided, said Brian O'Mara, co-chair of its governance committee. "The timing is really good right now for us to just take a hard look in the mirror and say, 'What can we change about the zoo and about ourselves, as a governing and oversight body?'" O'Mara said Wednesday evening.
