Supporters of the tax say it aims to bring more attractions, including a penguin, 1,000 new construction jobs, and will more than double the number of zoo workers.
But there is one costly catch.
Every time you go out to eat in Jackson or Clay counties, you'll pay an added 1/8 cent sales tax.
Senior researchers with the Mid-America Regional Council said that would amount to about $16 per person, per year.
"That stuff does eventually translate into economic prosperity," said Jeff Pinkerton, senior researcher with the Mid-America Regional Council. "They'll be more jobs available because of it, people are going to travel here to visit to see the zoo and just for a point of pride."
They also say with the increase in population expected in the area, that would also translate into added revenue for the zoo.
