Some who live in Royal Oak and Huntington Woods are saying that man-made noise from the increase in admissions, amplified music and early morning p-a announcements are disruptive.
There are also plans in the works for a new train that will run next to neighborhoods.
Ron Kagan spoke Monday regarding the complaints.
"People know when they move in here that they are living next to a place that attracts a million people a year," he said. "In 2014 we had 1.3 million. But we are well-within all of the ordinances.
"We are pretty rigorous about making sure we disturb people as little as possible. Whenever there are adjustments that need to be made we make them."
Zoo administrators want to hear your concerns.
