Wrap: Supporters said the measure would keep the attraction in top shape and continue to provide free admission.

Opponents said increased sales taxes would significantly affect the poor.

The measure would create a framework by which both St. Louis City and County could offer a one-eighth percent sales tax. Those increases would require voter approval.

If either locality refused to pass the sales tax increase, they could be charged for other programs beyond admission.

The bill passed the House with one-hundred and ten votes yes and forty-three no. The Senate passed the measure with thirty-one votes yes and two no. Only the governor's signature is necessary to make the bill law.

Wrap: Opponents said the measure would affect poor Missourians the most.

Supporters said because admission to the zoo must be free they need other revenue streams.

The measure would also cap city sales taxes to two percent and county taxes to one percent. However, St. Louis County would be allowed to raise their sales tax higher than other counties.

An approved amendment would not require sales taxes be reduced if they already exceed the new caps.

The bill would also require the purpose of any local sales tax increase be disclosed to voters. The taxes collected would then have to go to that stated purpose.
