According to the AZA, exhibit barriers made of glass or fiberglass are preferred over chain-link fences or iron bars.

Jackson said AZA officials also were concerned with the lack of financial planning needed to support the zoo's master plan.

"They had concerns our foundation for fundraising wasn't in place yet," Jackson said. "I was a little surprised by that, but I can understand where they're coming from. But they didn't really tell us anything we weren't aware of and working towards."

The zoo also was notified of the need for an on-site rapid-response team in the event a dangerous animal escapes or attacks a person. To comply with the plan, the zoo is working in conjunction with the Coal Valley Police Department. The zoo and police department have participated in two joint drills, and more are scheduled before the end of 2019.

According to the document, the zoo also has plans to purchase a CZ 550 American Safari Magnum firearm in the event a dangerous animal must be put down.
